Granted: 1988-03-24
Abstract: According to the invention, a round pipe is fitted vertically into the longitudinal duct of an air outlet device, as outlet pipe, said round pipe being mounted in a guide pipe, which is fixed to the outer wall of the ventilation duct, so as to be displaceable and/or rotatable in the axial direction. The round pipe has one or more air inlet openings constructed as a segment cutout. The rotary slide valve, arranged on the inside of the round pipe, can be displaced over the segment cutout, thereby making it possible to regulate the volume flow.

Title: Process for the continuous preparation of potassium sulphate from sodium sulphate
Inventor: SCHERZBERG HEINZ DR
IPC: C01D5/08
Filed: 1993-11-22
Granted: 1995-01-26
Abstract: The invention relates to a process for the continuous preparation of potassium sulphate from sodium sulphate by reaction of the sodium sulphate to give glaserite and glaserite mother liquor, reaction of the glaserite with potassium chloride and water to give potassium sulphate and potassium sulphate mother liquor and evaporation of the glaserite mother liquor with crystallisation of sodium chloride. To simplify the process substantially, particularly no longer to have to carry out a refrigeration of the glaserite mother liquor and a crystallization of Glauber's salt, it is proposed according to the invention   that the composition of the glaserite mother liquor be set to molar ratios of K2 : SO4 > 3 : 1 to a maximum of 5 : 1 and Na2 : SO4 > 6 : 1 to a maximum of 11 : 1, that there be drawn from this glaserite mother liquor, by evaporation at from 75 to 115 DEG C, from 29 to 42% of the water present, but at most that amount so that precipitation of sulphates, in particular of glaserite, is just avoided, that the pure sodium chloride which crystallizes out during the evaporation be separated off and that the hot crystal-free evaporation solution thus obtained be used, after cooling to below 40 DEG C, directly as KCl-containing suspension for the preparation of glaserite.
