Abstract

The invention relates to a method and device for preparing ammonium sulfate and sodium bicarbonate from sodium sulfate and ammonium bicarbonate, comprising pretreating the stock solution of sodium sulfate and the stock solution of ammonium bicarbonate, so that the sodium sulfate and ammonium bicarbonate pass through the electric field In the electrodialysis unit, the sodium ions and sulfate ions in the sodium sulfate stock solution and the ammonium ions and bicarbonate ions in the ammonium bicarbonate stock solution are recombined to form ammonium sulfate solution and sodium bicarbonate solution, and the ammonium sulfate solution and bicarbonate The sodium solution is exported to the evaporation crystallization unit to obtain ammonium sulfate crystals and sodium bicarbonate crystals. The present invention re-pairs the ions of the sodium sulfate stock solution and the ammonium bicarbonate stock solution through the electrodialysis module provided to form a concentrated solution, and obtains high-purity sodium bicarbonate crystals and ammonium sulfate crystals by evaporating and crystallizing the concentrated solution. The overall process There is no external agent in the process, which saves the cost of drug addition, the process flow is short, the required equipment occupies a small area, and the utilization rate of raw material agents is higher.

Description

technical field [0001] The invention relates to the field of chemical technology, in particular to a method and a device for preparing ammonium sulfate and sodium bicarbonate from sodium sulfate and ammonium bicarbonate. Background technique [0002] Soda ash, scientific name sodium carbonate (Na 2 CO 3 ), the form is usually white powder, it is not easy to decompose under high temperature conditions, it is easily soluble in water, and its aqueous solution is alkaline. Soda ash is an important basic chemical raw material and one of the two alkalis in the "three acids and two alkalis". It has the reputation of "the mother of chemical industry". It occupies a very important position in the national economy. The soda ash industry is a resource-dependent low-threshold industry. As an important basic industrial raw material, no matter whether it is soda ash or glass, there is no competitive substitute under the current technical conditions. Ammonium sulfate ((NH 4 ) 2 SO 4...
