LAMELLAR CONSTRUCTION FOR TREATING LIQUIDS

Abstract: The lamellar construction serves for treating liquids, in particular for the separation of solid and/or liquid particles from a liquid or for the contacting of the liquid with a gaseous substance or for the biological treatment by using e.g. a dropping body or a dipper rotatable disc or for cooling or degassing the liquid. The lamellar construction contains mutually parallel channels. The walls of the channels are expediently formed by circular cross-section partitioning elements with advantageously identical radius of the circular arcs, and in such a manner that the edges of the individual circles are disposed at the centres of the inside of the adjacent circular element or are connected thereto. The centre point of the circular arcs coincides with the every second intersection point of the square or rectangular matrix. In the intermediate spaces being formed around the intersection points of the square or rectangular matrix incorporating simultaneously the centres of the circular arcs, between the circular partitioning elements, one or more partitioning elements provided with downwards and/or upwards directed channel-like profiles or independent inserts are arranged, which are forming further channels being parallel with the former ones with partly or completely separated spaces, in the pitch lines of the square or rectangular matrix or lying symmetrically thereto.

Description: LAMELLAR CONSTRUCTION FOR TREATING LIQUIDS Techn ? cal field The present invention concerns a lamellar con¬ struction for treating liquids, principally 5 for the separation of solid and/or liquid particles from a liquid or for the contacting of the liquid with a gaseous substance or for the biological treatment by using e.g. a dropping body or a dipper rotary disc, or cooling of the liquid o or degassing of the liquid, containing mutually parallel channels, the wall of the channels being formed by circular cross-section partitioning elements in such a manner that the edges of the individual circles a re disposed at the 5 centres of the inside of the adjacent cir¬ cular element or are connected thereto, and the centre-point of the arcs coincide with the every second intersection point of a square or rectangular matrjx. o Background art Up-to-date water and effluent purification tech¬ nologies have throughout the world required the establishment of modern equipment for the separa¬ tion of liquids, in particular from the point of view of ecology (environmental protection). In course of several activities involving the water and effluent purification as well as thickening of sludges gra i tat i oneI separation OMPI ' of solid and/or liquid particles from a li¬ quid represents a fundamental demand. The task of sedimentation lies in ensuring an effluent being free of floating substances, 5 while the thickening of the sludges aims the production of a possibly densest sludge. Se¬ dimentation and thickening represent timely and spatially simultaneous processes. For the separation of particulate and/or sus- o pended solid materials from liquids by uti liz¬ ing the force of gravitation several gravita¬ tional sed imenfators with lamellar plates and divided spaces are known. In these sedimenta- tors, if possible, laminar flow conditions are 5 to be realized, which requires a possible small value of the Reynolds number. In order to ob¬ tain optϊmal _ sedimentation, the Reynolds-number is to be reduced, a-t the same time, the so- called Froude-number characterizing the flow o stability is to be increased. The sed imenfators hitherto known having been provided with plates or tubes, could not meet the requirements, accordingly their efficiency is restricted, as a result their size (space- 5 requirement) is large and hence they are un¬ economical, furtheron several operational dϊs- advantaαes are involved. Beside the tasks directed to sedimentation and thickening it might be necessary to separate o grav i tational ly substances from a liquid having a smaller specific gravity than that of the li¬ quid (water), as a consequence, these substances are floating on the surface of the liquid and water, respectively, therefrom they can be re¬ moved by the aid of special equipment. These equipment are called flotaion equipment or traps for floated matter. Regarding to their basic principle, the flota¬ tion equipment are substantially identical with the sed imentators, however, while sedimentϊng, the floating contamination used to be collected 1o in the surroundings of the bottom of the basin, whi le in the traps for floated matter it wi ll be accumulated on the water surface. The known floating equipment are unable to ensure with an ' optimal volume the dwelling period in the 5 equipment needed for the process, since the treat¬ ing surface related to the unit of volume is not sufficient at all, accordingly, their production and operation will be uneconomical. The efficiency of said equipment can be promoted o by flotation, in course of which air or gas bubb¬ les are injected, thus promoting the ascension of the floating particles. The eff ' cience of the hitherto known flotation equipment is restricted. For reasons similar to 5 those mentioned previously, the equipment are relatively uneconomical, so the equipment serv¬ ing for contacting different phases - in partic¬ ular liquids and gaseous media -, as well as the equipment serving for biological treatment hav- o ing a simi lar design. With one of the known OMPI dripping equipment to be considered as a modern desing, the lamellae having been bent in a trapezoidal line between cylinder mantles are yielding the contacting or biological treating 5 surfaces. By such an establishment treatment with a high efficiency cannot be obtained, since the contacting surface related to the unit of volume is relatively small. When outlining the invention, we started from o the solution having been described in the spe¬ cification of DE-OS 3 002 417. In said specifi¬ cation a lamellar construction has been de¬ scribed containing mutually parallel channels, the walls of the channels being formed by cir- 5 cular cross-section partitioning elements - preferably with identical radii - in such a manner that the edges of the individual circles are disposed at the centres of the insides of the adjacent circular elements or are connected o thereto, and that the centre-point of the arcs coincide with the every second intersection point of a square or rectangular matrix. It may be advantageous, if the pitch or spacing of said matrix is greater than the radius of 5 the circles. In order to increase the specific surface planar partitioning elements may be interposed between the circular cross-section partitioning elements along the lines of said matrix. o The lamellar construction having been described O PI in the specification of DE-OS 3 002 417 can be advantageously used for performing diverse sepa¬ ration tasks. The liquid to be treated can be led through the lamellar construction having 5 been build-in with an inclination into the pro- ber basin or receiver, i .e. through the chan¬ nels thereof, from the top or from the bottom, grav ϊ tat ional ly or pressurized. Disclosure of Invention 1o The task of the invention is partly to eliminate the disadvantageous features of the known equip¬ ment serving for the treatment of liquids, partly to provide a lamellar structure, which - ' compar¬ ed to the.known equipment - is representing an 15 equipment with a more efficient and more econom¬ ical operation. A further task lies in to es¬ tablish favourable conditions in the known equipment serving for different operations, in order to ensure the advantages of efficiency o and econo i calness - beside other surplus effects - as well as in course of performing gravitational sedimentation, as with flotation equipment, aeration, biological treatment, etc. Economical design and operation can be obtain- 5 ed in such a manner if we succeed to increase the specific surface, i.e. the treating surface related to the unit of volume. According to the invention the task set is solv¬ ed in such a manner that at the lamellar con¬ o struction according to the DE-OS 3 002 417 - as OMPI described in the preface - in the intermedi¬ ate spaces being formed between the circular partitioning elements, around the intersection points of the square or rectangular matrix in¬ corporating simultaneously the centres of the circular arcs, one or more partitioning elements provided with downwards and/or upwards directed channel-like profiles or Independent inserts are applied, which are forming further channels o being parallel with the former ones with partly or completely separated spaces, in the pith li¬ nes of the square or rectangular matrix or ly¬ ing symmetrically thereto. Both the downwards and/or upwards directed chan- 5 nel-like profile of the further partitioning element and the independent insert may have the most diverse shapes and cross-sections, accord¬ ingly, channels of the most different formation and cross-section, respectively, will be obtained. o So e.g. the downwards and/or upward ^ s directed channel-like profiles or the independent inserts may consist of arc-sections having been position¬ ed in the same sense as the circular partition¬ ing elements, being interconnected by a straight 5 section in the vicinity of the vertical pitch line of the matrix, running perpendicularly thereto. The channel-like profiles or the independent in¬ serts may have the shape of an open trapezoid, o furtheron the independent inserts may be compos¬ ed of two trapezoids lying opposite to each other. O It is possible to form the channel-like pro¬ files as squares, or in relation to the hori¬ zontal pitch line of the matrix as standing or lying rectangular profiles. 5 With a preferred embodiment of the invention the channel-like profile is formed as a semi -c ϊ rcular arc, or in case of an independent insert it may consist of one single insert having the shape of a circular arc, or of a double circular arc ly- 1o ing opposite to each other, running parallel or being turned to each other, at last of circular arcs forming mutually a closed or drawn apart circle, resp. of circles drawn apart and turned to each other with their convex parts. The cir- 15 cular arcs are arranged symmetrically in relation to the intersection point of the matrix. In a given case the circular arcs are interconnected by means of a straight section. It may be considered as advantageous, if the o channel-like profi le has the shape of an arcuate angle, or the independent insert is having the cross-section of an arcuate angle, an isosceles or uπisosceles arcuate square, respectively in a given case- cons ist i ng of arc elements drawn 5 apart. The channel-like profi le may advantageously have the shape of an ellipse, parabole or a siπe-wawe, however, a profile of the shape with facing S- l i nes can be also used. o With a preferred embodiment of the invention OMPI the channel-like profile Is formed in a U- shape, si ultaneously, the independent insert may also comprise one or two U-shaped inserts with parallel or diverging shanks. One single 5 insert may be drawn apart. In case of two in¬ serts they may be arranged opposite to each other or with the back-side turned to one an¬ other. It may be advantageous, if the channel-like o profile has the shape of a simple or double triangle, respectively, and the independent insert is consisting of one or two closed or open triangular profiles, in a given case with straight sheet sectioπ(s) being connected 5 thereto. With a further preferred embodiment the channel- -like profile has the shape of a semi-hexagon or the independent insert, has the cross-sec¬ tion of a closed hexagon. o An embodiment may be also considered as advan¬ tageous, with which the partitioning element Itself is formed in a channel-Like manner be¬ ing-connected to the two adjacent circular partitioning elements. 5 Beside the shapes already enumerated we wish to mention some further preferred embodiments of the independent insert. The independent insert may consist of one or two pairs of sheets diverging upwards; in case ^ ΕE _ OMFI of two pairs of sheets, they may be arranged identically or in a reversed manner. The independent insert may consist of one or more parallel, straight sheets; in case of several sheets, they are arranged under resp. beside each other and symmetrically with the intersection point. With a further preferred embodiment the cross- section of the independent insert is showing o the shape of an isosceles cross, the shanks of which are lying in the pith * lines" of " the matrix or they are enclosing an angle of 45 therewith. In a given case on the ends of the chanks sheet-sections - lying perpendicularly 5 thereto - may be arranged. A preferred cross-section of the independent insert consists of a rectangle having been arranged in the direction of the vertical pitch line of the matrix, as well as of a triangle o having been placed at the upper end thereof. With a preferred embodiment the independent insert is formed of a concentric double pipe- i nsert . It is possible to form the independent insert with a cross-section composed of one or more I-profiles, in case of more than one l-profile they are arranged beside each other and/or above one another, whereby on the end of the web OMPI - l o ¬ ot the l-profile, straight sheets or sheets having been bent at an angle are arranged perpendicularly to said web. It may be advantageous, if the independent in¬ sert consists of a planar sheet having been arranged in the vertical pith line of the mat¬ rix, while in the vicinity of the two ends thereof there is a double L-insert built-up of sheet-parts protruding perpendicularly to the , o left and to the right, respectively. The independent insert ma ' e formed horizont¬ ally as an H-shape lying symmetrically to the intersection point, In this case sheet-parts are arranged on the ends of the shanks, expediently 15 bent at an angle of 45 . Simultaneously, the independent insert may be formed of four sheets with a broken contour, while one shank each is running parallel with the vertical pitch line of the matrix and the other o shanks are forming a quadratic shape standing on Its corner. It may be considered as advantageous, if the independent insert is composed of four L-shapes, where the longer shanks of the L-shapes are 5 running parallel with the vertical pitch line of the matrix, whereas the shorter ones a re staying outwards from said pitch line. At last an embodiment is also possible, with O PI which the independent insert consists of two squares standing on their corners and having been arranged symmetrically to the intersec¬ tion point, drawn apart, i .e. being open in 5 the range of the corners, out of which the smaller one is located in the larger one. The lamellar construction according to the invention can be advantageously used for gra¬ vitational sedimentϊng or flotation equipment, 1o as well for sludge thickeners. With such con¬ structions the solid and/or liquid particles - which particles have a smaller specific gravity than that of the liquid - are as¬ cending on the upper partitioning elements 15 of the Inclined channels, resp, along thereof, onto the surface of the liquid, while the so¬ lid and/or liquid particles having a greater specific gravity than that of the liquid, are descending between the slant partitioning o elements to the lower parts of the liquid spa¬ ce, along the lower surfaces and edges resp. The matter thus separated, Leaving the lamellar construction according to the invention can be transported in a concentrated state for further 5 use, storage or annihilation, e.g. to incinera¬ tors . The advantage of the invention lies in the opti¬ mal material separation, since the treating sur¬ face is larger in relation to the streaming ve¬ o locity. As a result, a smaller volume of plant is required, so as to reduce the space or ground OMPI requirements while also reducing the investment and running costs. A further main advantage lies in that it can be built-in easily into already existing objects, 5 whereby the capacity thereof can be considerably increased. A futher advantageous feature is that the lamel¬ lar construction can be prefabricated, enabling economical and easy transport, simultaneously o montage in situ is also shorter. Instead of in situ assembling the lamellar construction can be prefabricated and transported in a steel-frame, similarly to a container, and simply lifted to its final place. In course of maintenance it t 5 can be simply lifted either as single elements or in an assembled state, accordingly, repair, washing and cleaning do not involve problems. The elements itselves can. be made of different materials, always taking ecoπomical ϊty and the o required function into consideration.

Oϋ_l"5.' i - - £ .!__.«__.1 Best Mode of Carrying out the Invention. Referring to the Fig. 1 it ' may be well seen that the lamellar construction - Indicated by the position number 1 in its entirety - is 5 built-up of the circular elements 2, which are meeting in every second intersection point of the square matrix consisting of the horizontal pitch lines 3 and the vertical pitch lines 4, while the centres of the circular arcs o are also coinciding with every second inter¬ section point 5. The Intermediate space 6 is formed around said intersection points 5 and forms substantially a channel. Between the circular partitioning elements 2 mutually intersecting 5 each other the channels 7 are formed. The pitch or spacing "t" of said matrix is somewhat larger than the radius "r" of the circular partitioning elements 2. In order to be able to increase the specific o surface related to the unit of colume, In the channel 6 the horizontal partition element 8 has been arranged, provided with a channel - like profile 8a - dierecfed downwards - in the vicinity of the intersection point 5. Said profile 5 8a consists of circular arcs having the same arching as the circular partitioning elements 2 configing the lower part of the channel 6, the circular arcs are interconnected at the bottom by a straight section running perpendicularly o to the pitch Line 4. The cross-sect-ion having been completed by the chanel-like profile has an increased specific surface resulting in a O PI considerable surplus both with., separation and the so-called "contacting" treatment of the liquids. In case of separation, collecting of the se- dimented sludges and floccules are facilitated in the channel, since in the lamellar con¬ struction 1 having been arranged ascew, the sludges may slide-off in an easier manner, where there s a s ludge dra i n i ng channel in the i n.termed i ate space 6. The partitioning 1o elements 8 having been build-in between the circular partitioning elements 2, as well as the channel-like profiles thereof, furtheron the independent—inserts - to be specified in detail later - are increasing about by 2o-4o# 5 the specific surface related to the unit of volume, resulting in a considerable surplus with all kinds of lamellar liquid treatment. The relatively large moistened periphery re¬ lated to the unit of the surface ensures a o relatively low so-called "hydraulic radius" - value, resulting in a low Reynolds-number. In such a manner a laminar stream and an In¬ creased separation can be achieved. In Fig. 2 the channel-like profile 8b of the 5 partitioning element 8, directed upwards, is to be seen. This arrangement is to be consi¬ dered as advantageous, when the separation of substances having a smaller specific gravity than that of the liquid, so e.g. oils and o fats, is involved. Such a substance is collec¬ ted in the channel part pointing upwards and is streaming upwards in the channels towards the surface of the liquid, where It is accu¬ mulated and can be removed in a concentrated state therefrom. In Fig. 3 the combination of the embodiments 5 according to Fig. 1 and 2, respectively, can be seen, where the profiles 8a and 8b are arranged symmetrically in relation to the horizontal pitch line 3. This arrangement is to be considered as advantageous when the o lamellar construction is positioned vertically, i.e. the direction of the channels is also vertical, so e.g. when applied in degassing cooling towers or as dripping bodies, i.e. when the lamellar construction is performing 5 its function as a space-filling body and w ' here the largest possible contacting surface has been required. The solution according to the invention can be advantageously used, when the lamellar o construction is applied in a biological water purifier provided with a so-called dipping - or rotatable dis. In this case the lamellar construction is formed as a rotatable horizon- tal cylinder, which is immersed into the II- 5 quid to be treated, e.g. into the sewage about to two-third of its volume. In this case too the establishment of a specifically large con¬ tacting surface is of utmost importance, since in such a manner a more advantageous oxygen o transfer, the more intense decomposition of the organic substances can be achieved, ac¬ cordingly, the efficiency of sewage purific f - ^--- - energy requirement of the liquid treating system can be reduced, yielding further energy sav i ngs . In Fig. 4 a preferred embodiment of the chan¬ nel-like profi le may be seen, with which the channel-like profile 9a directed downwards and 9b directed upwards are formed with S-shaped side-walls turned towards one another, and with slightly arched longitudinal sides. In Fig. 5 to 15 some further preferred embodi¬ ments of the independent insert a re to be seen; for the sake of order it should be mentioned that a large number of inserts consisting of similar elements and formed in a simi lar man- ner can be used without departing from the scope of the invention. _ Q MPI
