Solutions to the clogging of stainless steel heat exchanger

(Summary description)The clogging of the stainless steel heat exchanger is a headache for many friends. Generally, particles with a diameter greater than 1.5~3mm are easy to block the plate passage (the flow channel gap of the plate heat exchanger is small, generally 2.5~6mm), the pressure drop of the equipment deteriorates sharply, which causes the stainless steel heat exchanger to be greatly blocked due to the blockage.

Information

The clogging of the stainless steel heat exchanger is a headache for many friends. Generally, particles with a diameter greater than 1.5~3mm are easy to block the plate passage (the flow channel gap of the plate heat exchanger is small, generally 2.5~6mm), the pressure drop of the equipment deteriorates sharply, which causes the stainless steel heat exchanger to be greatly blocked due to the blockage. Reduce the heat exchange capacity, seriously causing the continuous production interruption of the equipment. Therefore, it is urgent to solve the problem of the blockage of the stainless steel heat exchanger.

stainless steel heat exchanger
The stainless steel heat exchanger manufacturers have summarized the experience for many years and found out three ways to solve the blockage of the stainless steel heat exchanger:
1. When designing and installing, a coarse filter or backwashing device can be installed at the medium inlet of the stainless steel heat exchanger, which can effectively prevent the blockage of the plate heat exchanger.
2. The stainless steel heat exchanger should not be used in a dirty or fouling environment (unless other effective measures are added). The operating temperature of the heat exchanger should be controlled at about 50°C or lower.
3. When using unsoftened cooling water as the cooling medium, avoid the sensitive temperature of the precipitation of calcium and magnesium ions in the medium. According to the different characteristics of the heat exchange medium of the heat exchanger, periodic chemical cleaning or disassembly and washing is also very effective.
During the use of the stainless steel heat exchanger, it is difficult to maintain the original performance due to deterioration of the seal ring and adhesion of stains, and various problems such as liquid leakage sometimes occur. In order to make the stainless steel heat exchanger be able to be used more long-term, stably, and in a good condition, regular maintenance is indispensable.
