Chemical plant plate heat exchanger failure problems appear after we seem to have no good way, in fact, in the first time you can do a lot of things to solve or avoid the emergence of more problems or delay production, the following details of these methods.

Chemical plant plate heat exchanger mainly in three areas: first, scaling. Fouling will reduce the heat transfer coefficient and will also cause the plate channel blockage. The plate has a large number of support a contact, is a solid surface impurities or fibers easy to collect where it is easy to make the fluid to form a kind of local stagnation and scaling.

Precautionary measures.

1?The equipment is not suitable for working under dirty or easy scaling conditions.

2?When the medium uses unsoftened cooling water, the working temperature should be set below 50 degrees.

Second, blockage. Because of the small gap of the flow channel, the diameter of foreign matter is greater than 1.5~3.0mm will be easy to block the channel, resulting in equipment failure.

Preventive measures: Install coarse filters or flushing systems and other devices at the inlet of the medium to prevent blockage and improve the heat exchange effect.

Third, leakage. Because of seal failure caused by leakage within the working environment pressure, except for the factors of the equipment, mainly related to the rapid changes in pressure and temperature. The instantaneous pressure drop caused by the shock will generally be 2 to 3 times higher than normal, causing the rubber gasket position to change, which leads to seal failure. Another situation is when the temperature changes too quickly, the elasticity of the gasket does not match the sealing preload, resulting in a lower pressure-bearing capacity of the equipment than the rated design pressure, causing leakage.

Preventive measures.

1. Try to avoid the impact phenomenon in actual use or operation.

2. Take other measures to make the seal preload match.

3. In actual use, the process of temperature and pressure increase should be as slow as possible.
