How to clean a graphite heat exchanger?

For the cleaning work of the five ink heat exchanger, chemical cleaning methods can be used. Before cleaning, it should be confirmed that the surface of the equipment is in a clean state, without obvious defects, and there should be a passivation protective film on the surface. Each component should be inspected one by one, and if the defect is severe, necessary replacement should be carried out before cleaning.

When disassembling the various components of a graphite heat exchanger, the first priority is to solve the bolts used for connection. Attention should be paid to avoiding the use of hammers or other destructive tools to violently disassemble the bolt parts. Of course, using cutting or other methods is not allowed. When lifting and transporting graphite heat exchangers and other components, attention should be paid to avoiding collisions as much as possible to avoid damage to the equipment.

Before carrying out dismantling work, it is necessary to carefully observe each component, such as tube sheets, graphite blocks, etc., for any signs of damage, and whether there are any signs of leakage inside the graphite heat exchanger. Conduct a water pressure test to ensure that there are no signs of leakage in the various components of the equipment before it can be put into use.

A pressure test should be conducted on the graphite heat exchanger to check for any leaks. If there are any, they must be plugged before chemical cleaning can be carried out. The addition of cleaning medium should ensure that it fills the entire interior of the equipment and no dead corners are allowed to occur.
