Patent GB-171370-A (GB)
IPC: B01D9/00
Filed: 1921-10-14
Abstract: 171,370. Aktieselskabet de Norske Saltverker. Nov. 9, 1920, [Convention date]. Crystallizing; separate heater and evaporator apparatus.-Granular crystals, for example, of sodium chloride, are obtained from solutions by supersaturating a solution out of contact with crystals by evaporation or by cooling, and circulating the supersaturated solution through a mass of crystals which are caused to grow. The agitation of the mass of crystals may cause the formation of spherical granules. The solution drawn from an evaporating-chamber b, Fig. 1, is forced by a pump g through a superheater a and pipe i back to the evaporating-chamber. Evaporation takes place at the upper surface o and the supersaturated solution is drawn upwards through an inner chamber e containing a mass of crystals.. When the crystals have attained a certain size they fall against the flow of the liquid into the base of the vessel e and are discharged through an opening h and through a. pipe m to an elevatorn. Curved baffles q inside the vessel e cause all parts of the crystal mass. to pass over the opening h. A current of liquid admitted to the base of the chamber b passes upwards through the opening h to prevent passage of small crystals. When the solubility of the substance does not increase rapidly with the temperature, the solution may be passed through the superheater a, Fig. 2, directly into the crystallizing vessel e and thence into the evaporating vessel b. The small crystals may be removed from the circulating current of solution by filtration, centrifugal treatment, or by settling, or the discharge opening h may be arranged so that some small crystals are discharged with the large crystals. Supersaturation of the solution may be effected by cooling the solution at the surface o of the vessel b, the superheater a being dispensed with. The evaporation or cooling may be accelerated by blowing air through the solution. Small crystals are added to the circulating current to serve as nuclei. The Specification as open to inspection under Sect. 91 (3) (a) describes also that to prevent fine crystals being carried from the crystallizing vessel, fresh solution may be fed 'by a jet discharging into an open coiled pipe or a chamber in the upper part of the vessel e. This subject-matter does not appear in the Specification as accepted.
