Abstract

The invention provides anhydrous sodium sulfate production equipment which comprises a nitrate dissolving tank, a feed pump, a first heat exchanger, a circulating pump, a second heat exchanger, a condensate pump, a centrifugal machine, a DTB evaporation crystallizer, an MVR (Mechanical Vapor Recompression) compressor and a steam supplementing pipeline. According to the anhydrous sodium sulfate production equipment disclosed by the invention, the nitrate dissolving energy consumption is reduced by utilizing heat of the feed liquid discharged by the DTB evaporation crystallizer and the mother liquor discharged by the centrifugal machine, the anhydrous sodium sulfate production equipment is simple in technical process, compact in equipment arrangement and reasonable in energy utilization, andmultiple advantages of saving investment, shortening the process flow, reducing the cost, comprehensively utilizing resources, protecting the environment and the like are fully achieved; moreover, the anhydrous sodium sulfate production equipment has the advantages that the product liquidity is excellent, the stock bin is difficult to block, the stored material is difficult to agglomerate, the drying energy consumption is reduced, the dust pollution is reduced, the product cost is low.

Description

technical field [0001] The invention belongs to the field of sodium sulfate production, and in particular relates to a production equipment for sodium sulfate. Background technique [0002] Sodium sulfate generally refers to sodium sulfate. Sodium sulfate is a salt formed by the combination of sulfate radical and sodium ion. Sodium sulfate is soluble in water and its aqueous solution is weakly alkaline, soluble in glycerin but not in ethanol. Sodium sodium sulfate is mainly used in detergent, soda sulfide, sodium sulfide, papermaking, glass, textile, printing and dyeing, vinylon and other industries. The existing sodium sulfate production equipment mostly adopts the multi-effect evaporation method, but the multi-effect evaporation method occupies a large area, the control system is relatively complicated, and the nitric acid dissolution tank needs to be additionally equipped with a forced circulation heater, and the operating cost is high. Contents of the invention [000...
