Technical field
The present invention relates to a kind of equipment that reclaims ammonium chloride from glycin mother liquid, specifically comprise two effect evaporation concentration equipments and continuous crystallisation equipment.
Background technology
Take Mono Chloro Acetic Acid and liquefied ammonia as the raw material production glycine, contain two kinds of materials of glycine and ammonium chloride in the solution after having reacted simultaneously; After isolating glycine by methanol extraction, contain a large amount of ammonium chloride byproducts in its mother liquor.If the mother liquor that these are contained to a large amount of ammonium chlorides is discarded, not only can causes environmental pollution, and cause the waste of resource.To be that the mother liquor that will contain ammonium chloride is concentrated in vaporizer separate and obtain ammonium chloride product by intermittent type cooling crystallizer, separating machine traditional equipment.There are the shortcomings such as continuity of operation is poor, production capacity is limited, the plant area area is large in this equipment.
Summary of the invention
The object of the present invention is to provide a kind of equipment that reclaims ammonium chloride from glycin mother liquid, comprise evaporation concentration equipment and continuous crystallisation equipment.I effect well heater top connects I single-effect evaporator opening for feed, the bottom of I single-effect evaporator connects respectively II effect well heater top and I effect well heater bottom, wherein the I single-effect evaporator is positioned on II effect well heater, both form liquid level difference, II effect well heater top connects II single-effect evaporator opening for feed, II single-effect evaporator top is imitated separator by II and is connected I effect well heater steam inlet, and II single-effect evaporator bottom connects II effect well heater bottom and connects the flasher opening for feed by discharging pump; Flasher bottom discharge port is connected with continuous crystallizer top fed mouth by discharging pump, and continuous crystallizer bottom discharge mouth sets gradually thickener, whizzer and feed bin from top to bottom by liquid level difference.
Described I single-effect evaporator imitates separator by I and I effect condenser is connected with vacuum buffer tank; The flasher top is imitated condenser by I and is connected with vacuum buffer tank, and wherein vacuum buffer tank is connected vacuum pump.
The carrier pipe of described flasher connects the opening for feed of flasher by discharging pump.
Described continuous crystallizer discharge port is connected with the continuous crystallizer opening for feed by discharging pump and interchanger.
