Description

Technical Field

[0001] The utility model relates to the technical field of deaerator equipment, in particular to a novel shell and tube heat exchanger which is convenient for cleaning. Background Art

[0002] Shell and tube heat exchanger is a common heat exchange equipment used to transfer heat between two different media. In order to maintain its effectiveness and performance, regular internal cleaning is necessary. The goals of internal cleaning usually include removing scale, sediment, algae, corrosion products, etc. to ensure the heat transfer efficiency of the heat exchanger. Steps and methods for cleaning the inside of a shell and tube heat exchanger:

[0003] Shut down the equipment: Before cleaning, make sure to shut down and isolate the shell and tube heat exchanger to avoid accidents during cleaning.

[0004] Drain the medium: Drain the medium in the heat exchanger to ensure that the system is in a safe state.

[0005] Removing the End Covers: If possible, remove the end covers of the shell and tube heat exchanger to allow easier access to the interior.

[0006] Inspect the tube bundle: Inspect the tube bundle (collection of tubes) to determine if there is any visible corrosion, dirt or deposits.

[0007] However, the existing method of cleaning shell and tube heat exchangers is relatively complicated. It is usually necessary to remove the end cover and then use a cleaning tool to clean the inside of the heat exchanger. However, this method requires the end cover to be removed during actual operation and the deep inside of the heat exchanger cannot be effectively cleaned, resulting in low work efficiency.
