The use of plate heat exchanger plate cleaning agents can effectively remove scale, rust, and other deposits from the heat exchanger plates. Here are the detailed steps for use:
Preparation of the Cleaning System: First, prepare a cleaning circulation system, including acid-resistant pumps and piping. Ensure that the amount of cleaning agent is at least equal to the normal working volume of the heat exchanger. If the viscosity of the dirt is high, it may be necessary to increase the amount of cleaning agent.
Circulation Cleaning: Use a pump to continuously circulate an adequate amount of cleaning agent into the interior pipes of the heat exchanger for no less than 1 hour. The longer the circulation time, the cleaner the result. Depending on the severity of the dirt, it may be necessary to add more cleaning agent in time or replace it with a new one.
Rinsing and Neutralization: After the cleaning is complete, drain the residual liquid inside and use cold or warm water to circulate and flush the interior pipes of the heat exchanger until all residual liquid is completely flushed out. As needed, a "neutralization treatment agent" can be used to neutralize before discharge.
Passivation Treatment: After the water rinse is qualified, circulate and add a "passivation pre-filming agent" for passivation treatment to enhance the corrosion resistance of the copper tubes. Stop the circulation after the solution concentration in the entire system is evenly mixed and soak for 2-3 hours.
Inspection and Maintenance: During the cleaning process, it is important to check for system leaks and remove loose dirt inside the coils. In addition, regular cleaning and maintenance can extend the service life of the equipment.
Please note that when using cleaning agents, follow the manufacturer's instructions and take necessary safety precautions. If you are unsure how to operate, it is recommended to consult a professional.
