Technical Field

The utility model relates to a mirabilite production facility, especially a high potential difference powder conveying equipment.

Background

Anhydrous sodium sulfate is also called anhydrous sodium sulfate, anhydrous sodium sulfate; white fine crystals or powder, easily soluble in water, hygroscopic, odorless, and nontoxic. Sodium sulfate forms heptahydrate and decahydrate, and heptahydrate (Na2SO4 & 7H2O) is white orthorhombic crystal. The anhydride was converted on heating to 24.4 ℃. Sodium sulfate is reduced to sodium sulfide when reacting with carbon at high temperature; therefore, the method is widely used for manufacturing sodium sulfide, sodium silicate and the like, and is also used for processes of papermaking, glass, printing and dyeing, synthetic fiber, leather making, food, chemical engineering and the like. In addition, the catalyst is also used as a blending agent of non-ferrous metal ore dressing, porcelain glaze, rubber, chemical fertilizer and light materials, and is also an additive of cement and concrete and a catalyst for synthesizing and preparing organic chemical products.

The traditional process flow of preparing the mirabilite is to evaporate and concentrate the mirabilite water to form supersaturated solution of the mirabilite, separate out mirabilite crystal by centrifugation, and then dry the mirabilite crystal to prepare the mirabilite, and the mirabilite produced like this will agglomerate after being stored for a certain time, thereby causing much inconvenience in use.

In chinese patent No. CN: 00112995.3 discloses a method for producing thenardite by cooling, hot melting and hot melting tower, mainly using cooling saltwater to crystallize saltwater, then removing crystal water from saltwater crystal by hot melting, although the method has short process flow, the power consumption is large, most mainly using refrigerator to circularly cool saltwater, because the method is an open process flow, at the same time, the method can only use intermittent production mode; the mirabilite thus obtained is finally caked after being piled up for a long time.
