Innovative Multiple-Effect Evaporator for Cost-Effective Wastewater Treatment in The Environmental Industry

Application
Single-effect forced circulation evaporator is a high-efficiency and energy-saving concentrator. It works under condition of vacuum and low temperature, has features of high flow velocity, rapid evaporation, free of fouling. It is suitable for concentration of viscosity and high concentration materials and is widely supplied in crystallization, production of fruit jam, flesh type juice, etc.
Features
1. Evaporation under vacuum condition, low evaporating temperature,
2. Continuous input and output
3. Forced circulating evaporation, make feed liquid at high viscosity and high concentration easily evaporated, not easy fouling, shorter concentrating time,
4. Independent heater and separator, convenient for washing and replacing tubes.
5. All parts are made from stainless steel, parts contact with materials are polished finish, external parts are pickling or matte finishing.

Structure Principle
Single-effect forced circulation evaporator is composed of heater, 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: Two sets of vertical type tubular heater connect in series. 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.
