The heat exchanger is divided into plate heat exchanger, spiral heat exchanger, tubular heat exchanger, tank heat exchanger, etc. the materials are mostly stainless steel or copper. Generally, the secondary water is easy to scale, so it should be cleaned and descaled in time to avoid affecting the heat exchange. The plate heat exchanger can be disassembled and soaked for cleaning.

The heat exchanger can be cleaned with solid acid pickling and scale remover, which has strong corrosion inhibition, no corrosivity to the equipment, good safety and no danger to the construction personnel. The agent shall be dissolved evenly during cleaning, soaked in warm water below 60 ℃ or circularly cleaned, and appropriate amount of cleaning corrosion inhibitor can be added during cleaning (optional). After cleaning, hrc-q103 neutralizing and passivating agent should be added. Neutralize the residual acid to form a passivation film on the metal surface to prevent the formation of floating rust. After passivation, it can be washed repeatedly with clean water.
