Inorganic Salt Effluent Desalination Double effect Self cleaning Evaporator

Application

Double-effect Self-cleaning Evaporator is flexible for various kinds of wastewater, including Inorganic Wastewater and organic wastewater, such as Sodium chloride wastewater, Phenylalanine wastewater, sodium sulfate wastewater, ammonium chloride wastewater, glycine, barium chloride wastewater, zinc sulfate wastewater, calcium chloride wastewater, ammonium sulfate wastewater, etc.

Wastewater treatment evaporator works under vacuum condition, has large heat exchange area per unit volume, forced circulation to avoid scaling and fouling. It could be supplied not only for treating wastwater, but also producing inorganic salts and concentrating materials which are thick and viscosity.

Structure and Principle

 Double-effect Self-cleaning Evaporator is composed of 1st effect heater, 2nd effect heater, 1st effect separator, 2nd effect separator, vapor-liquid separator, condenser, vacuum pump, forced circulation pump, discharging pump, condensate pump, electrical cabinet, operation platform and all the pipe fittings, valves, instruments and etc.

Heater: vertical type tubular heater . The feed liquid is pumped into the first heater by forced circulation pump, then enters into the second heater. The heated liquid flow downwards in tubes, and flow into separator by tangential direction, better performance of vapor-liquid separation.

Separator: vertical type, the secondary steam is discharged from the top, pass through a vapor-liquid separator before entering into condenser. The bottom of separator is connected with a forced circulation pump.

Vapor-liquid separator: is used to prevent tiny liquid drops produced during evaporation from escaping with secondary steam, reducing loss of feed liquid and prevent pollution to pipeline and cooling water.

Condenser: condensate the huge secondary steam produced during evaporation into liquid by cooling water, making concentration carrying on smoothly. Meanwhile, separate non-condensable vapor from secondary steam and cooling water, make it easily pumped out by vacuum pump to guarantee vacuum degree.
