Workers need to hold a cleaning gun (high-pressure water gun or mechanical cleaning gun) and clean the interior of each small pipe in the heat exchanger tube bundle one by one. This operation method has obvious defects:

[0004] 1. There are safety hazards in the working environment: After the pipes in the heat exchanger tube bundle have been in operation for a long time, the toxic and harmful gases and high-temperature media remaining inside bring potential health risks to the workers who rely solely on manual labor.
