Description

Technical Field

[0001] The utility model relates to the technical field of heat exchanger tube bundle cleaning, in particular to a heat exchanger tube bundle cleaning device. Background Art

[0002] Heat exchangers are the most commonly used heat exchange equipment in chemical production equipment. Heat exchangers use the temperature difference between hot and cold media to exchange heat inside and between heat exchange tubes to ensure that the temperature of the cooled medium reaches the process conditions. After the cooler has been used for a period of time, dirt deposits will inevitably appear on the heat exchange surface, resulting in scaling. The dirt can significantly reduce the life of the heat exchanger. The thermal resistance of the dirt deposits is high, which greatly reduces the thermal conductivity. The dirt seriously causes blockage, reduces the fluid flow rate, increases the flow resistance of the fluid medium, and increases energy consumption. Therefore, it is necessary to clean and descale the heat exchanger. The quality and duration of the heat exchanger operation are closely related to whether the daily maintenance, cleaning and maintenance are timely.

[0003] At present, we mainly use high-pressure water cleaning to clean the heat exchanger tube bundle, that is, use a pressure water truck to increase the water pressure to a suitable kilogram, and then use a cleaning nozzle to insert into the tube bundle for cleaning to rinse the dirt on the tube wall. Through actual operation verification, it is found that as the operating time increases, more and more scale will remain in the tube wall after high-pressure water cleaning. At this time, if high-pressure water cleaning is used alone, the overall cleaning effect will become very poor, and the operation cycle of the heat exchanger cannot be guaranteed at all. Therefore, it is urgent to study how to quickly and efficiently clean the dirt on the tube wall without affecting the heat exchange efficiency of the heat exchanger. Utility Model Content
