1. Function description: an evaporator (temperature 25-40 ºC) for treating water-based liquid based on vacuum and heat pump technology;

3.1,technological process:
    The liquid to be treated is sucked into distilling chamber D01, and vacuum is generated in the distilling chamber under the action of G01. The feedback signal from EV01 liquid level sensor is sent to PLC, and the PLC controls VM02 to open and close. The bottom of the distillation chamber consists of a coil heat exchanger E01. The refrigerant R134A of the heat pump circuit flows into the heat exchanger E01. The liquid to be treated contacts the E01 heat exchanger and is heated to boil. The steam rises through the demister. The refrigerant generated by the steam and E02 exchanges heat and cold through the circulating water in G02 and F01. The distillate and non condensable gas are taken together and sent to the storage tank D02 by G01. The distillate is discharged through overflow, and the non condensable gas and liquid are discharged together. The concentrate is discharged through valves VM01 and G03 after the cycle is completed;

3.2,vacuum system
   The vacuum system is composed of a multi-stage centrifugal pump and an ejector. The ejector adopts the Venturi principle and uses the distillate produced by the evaporator as the motor power fluid. The efficiency of the vacuum system depends on the temperature of the motor fluid. The opening of valve VM03 can destroy the vacuum in the evaporation chamber;

3.3,Heat pump circuit
   The heat required for evaporating liquid and the cooling capacity required for condensing steam are provided by the heat pump circuit. The refrigerant in the gas phase is compressed by the compressor, flows into the E01 plate heat exchanger, and releases the heat to the liquid. The refrigeration after releasing the heat is cooled. The auxiliary fin radiator K02 starts the secondary heat exchange according to the set conditions, and any excess heat is released to the environment. The liquid phase refrigerant flows through the filter to the expansion valve. After throttling, the refrigerant with low temperature and pressure is generated, which is used to condense the cooling capacity required by the steam;

3.4,Auxiliary liquid 
Foam inhibitor is supplied by valve VM04;

1. Installation requirements

The machine is designed to be installed in a safe area with non corrosive atmosphere. The indoor horizontal surface is flat and can support the weight of the equipment itself; There must be a space around the equipment to ensure smooth operation of users and maintenance personnel, and allow cold air to pass through the ventilator. The characteristics of liquid connections and pipes are as follows:

Serial No	description	type	caliber	requirement
1	Liquid inlet to be treated	Reserved internal teeth	1 inch internal tooth
2	Concentrate discharge outlet	Reserved internal teeth	1 inch internal tooth
3	Defoamer inlet	Reserved air pipe orifice	6 cm straight plug
4	Distillate outlet	Reserved internal teeth	6 internal teeth
5	Tap water inlet	Reserved internal teeth	1 inch internal tooth

  The non condensable gas that may be discharged is discharged into the pipeline through the distillate.
The following facilities are required for equipment operation:
