Title: Scrubbing water treatment for the simultaneous removal of SO2 and NOx from gases
Inventor: HOELTER HEINZ DIPL ING
IPC: B01D53/68
Filed: 1985-08-31
Abstract: In the main application P 3526003.3, the scrubbing water treatment in the simultaneous removal of SO2 and NOx is described, a part-stream of the scrubbing circulation being treated with Ca(OH)2 at pH 12-pH 13, CaSO3 and CaSO4 being partly precipitated and iron being completely precipitated. In addition, the reduction of the Fe III ions and the formation of CaSO4 are described. It has now been found that the precipitation with Ca(OH)2 is performed particularly effectively by employing calcium hydroxide for the precipitation of a part-stream of the scrubbing water circulation and optimal precipitation conditions are achieved by establishing the sulphite concentration in the scrubbing circulation between 5 and 15 g/l and the sulphate concentration between 30 and 80 g/l and improving the gypsum quality by complexing agents. Flue gas and/or CO2 are introduced during the precipitation process. The calcium hydroxide can be added in solid form or as a suspension with fresh water and/or scrubbing liquid to the SO2/NOx purification for precipitation.

Title: Liquid-cooled electrical machine
Inventor: WULF HELMUT DIPL ING
IPC: H02K9/19
Filed: 1986-01-16
Abstract: The invention relates to a liquid-cooled electrical machine which is constructed as an electric motor and is used as an alternative drive - in addition to an internal combustion engine drive - for a bus. In order to be able to cool such an electric motor with a high power concentration and a small structural volume without any problems, a water jacket is placed around the stator. In addition, the rotor is provided with a cooling circuit which is integrated in the rotor and is either constructed as a heat tube and emits its heat directly to the cooling circuit or can be acted on directly by cooling water. A centrifugal pump (rotary pump) is integrated in the rotor, which pump utilises the density difference between the cold cooling medium and the hot cooling medium in order to maintain circulation. The same water can be used as the cooling medium as that which is also used for cooling the internal combustion engine which is likewise installed on the bus.

Title: Treatment of gas scrubber effluents
Inventor: FORM MICHAEL DIPL CHEM DR
IPC: C02F1/58
Filed: 1986-05-16
Abstract: For the treatment of effluent from a gas scrubber, in which sulphur dioxide and nitogen oxides are separated from waste gases, a process is proposed, by means of which the costs for final storage of the non-utilisable residual materials can be considerably lowered. For this purpose, the pH in a part stream of the scrubbing water circulation is adjusted to 0.5-2 by addition of mineral acid, and CaSO4 and H4EDTA are separated off. Subsequently, the part stream is not evaporated as hitherto usual, but the S-N compounds contained therein are first hydrolysed, the part stream is then neutralised and stripped of ammonia before it is evaporated and any Na2SO4 is separated off in the form of Glauber's salt. In addition to a cost saving of about 40 % in the final storage of the non-utilisable residual materials, marketable products, namely ammonia and gypsum, are recovered in the process according to the invention.

Title: Method for making uniform and preferably dividing a flowing carrier fluid, non-uniformly loaded with solids, and apparatus for carrying out the method
Inventor: MOHR KARL-HEINZ PROF DR ING
IPC: F23K3/02
Filed: 1986-08-08
Abstract: The invention relates to a method for making uniform and preferably dividing a flowing carrier fluid, non-uniformly loaded with solids, and an apparatus for carrying out the method. The solids, for example coal dust, are separated from the carrier fluid, for example air, in an apparatus combined to form a module, the solids, which are present in strand and non-uniformly, are settled and collected and added back to the fluid uniformly. The mixture made uniform can be fed to downstream apparatuses, e.g. burners, which demand a uniform distribution of solids over the flow cross section, or the mixture can be divided by a divider into any desired number of mixture part-streams and then fed, for example, to a plurality of burners, each mixture part-stream containing roughly the same amount of solids and fluid. The separation of solids and fluids can advantageously be carried out by a tangential or axial cyclone and the settling and collecting of the solid strands with the aid of a short-term reservoir. The division of the mixture made uniform can be carried out by the aid of a geometric cross-section subdivision. The apparatus exhibits a low pressure drop and low abrasion and can be designed to be pressure- and explosion-resistant. <IMAGE>
