Plate heat exchanger

The steps for putting a plate heat exchanger into operation are as follows: 1. Check whether the plate heat exchanger is installed correctly, including whether the pipe connections are tight and whether the flanges are securely fixed. 2. Pipes and valves for connecting the cold medium and the hot medium. 3. Open the valves for the hot medium inlet and outlet, close the valves for the cold medium inlet and outlet, and adjust the outlet valves to be fully open or partially open as needed. 4. Turn on the pump to drain the condensate from the heat exchanger until no gas remains inside it. 5. If preheating is required, it can be done before operation. During preheating, heating should be carried out to the set temperature based on actual conditions. 6. Concentrated brine is fed into the plate heat exchanger as a refrigerant, and the flow rate and temperature are adjusted by controlling the inlet and outlet valves. 7. When condensate water is used as a heat transfer medium and fed into the plate heat exchanger, it is also necessary to control the flow rate and temperature by regulating the inlet and outlet valves. 8. During normal operation, the heat exchanger needs to be monitored and maintained to ensure its proper functioning and to maintain good heat exchange efficiency. It should be noted that the interior of the heat exchanger needs to be inspected and cleaned before each operation to ensure it is clean and hygienic. Additionally, if it is being used for the first time, more thorough inspection and testing are also required to ensure its safe and reliable operation. .

First, introduce cold water when starting up; once the cold water circulation is stable, then introduce the refrigerant； When shutting down, turn off the refrigerant first and then run cold water for a while to prevent it from freezing.
