Embodiment

[0011] Example: The structure of the sodium chloride evaporation crystallization device provided by the present invention is as figure 1 As shown, it includes a first effect evaporation unit 1, a second effect evaporation unit 2 and a third effect evaporation unit 3 connected in sequence. The purpose of saving steam is achieved by adopting a multi-effect device, and each effect evaporation unit is The circulation pump is used for forced circulation, so that the material has a faster processing speed and evaporation speed in the system.

[0012] The first effect evaporation unit 1 is connected to the steam input pipe, and the steam passes through the heaters of the first effect evaporation unit 1, the second effect evaporation unit 2 and the third effect evaporation unit 3 and then is condensed and recovered, and the temperature is sequentially reduced. The first effect evaporation unit 1 is connected to the feeding tank 5, and the sewage containing sodium chloride passes through ...

Abstract

The invention discloses a sodium chloride evaporation crystallization device which comprises a first effect evaporation unit, a second effect evaporation unit and a third effect evaporation unit which are connected in sequence, the first effect evaporation unit is connected with a steam input pipe and a feeding groove, a gas phase tube of the third effect evaporation unit is connected to a surface condenser, a crystal slurry pipe of the third effect evaporation unit is connected to a centrifuge, the centrifuge is provided with a solid salt output end and a mother liquor tube, and the mother liquor tube is connected to a mother liquor tank; a throttling gear is arranged on a connecting pipe of a separator and heating column tubes in the first effect evaporation unit, the second effect evaporation unit and the third effect evaporation unit; a vacuum pump is arranged on the surface condenser, and the surface condenser and a cooling tower form a cooling loop; evaporation condensate tubes of the second effect evaporation unit, the third effect evaporation unit and the surface condenser are connected to a condensate collection groove. The sodium chloride evaporation crystallization device has the advantages of high operation concentration and less reflux mother liquor.

Description

Technical field [0001] The invention relates to an evaporation separation equipment, in particular to a sodium chloride evaporation crystallization device. Background technique [0002] Evaporative crystallization devices are widely used in the chemical industry, non-ferrous metal industry, pesticide industry, food industry, pharmaceutical industry, and wastewater treatment in ammonia desulfurization, mining and smelting, steel mills, oil fields and other industries. Through the recovery of crystals in the wastewater, the pure Environmental protection governance and compliance discharge are deepened into environmental protection governance and comprehensive utilization. Not only can the ammonium chloride, potassium chloride, sodium chloride and other crystals in the waste water be recycled and reused, but the evaporated water can meet the national discharge standards. [0003] Due to the characteristics of sodium chloride materials, the solubility of sodium chloride is not affecte...
