Description

Technical Field

[0001] The present application relates to the technical field of mechanical cleaning equipment, and more specifically, to a heat exchanger cleaning device. Background Art

[0002] A heat exchanger is an energy-saving device that transfers heat between two or more fluids at different temperatures. Heat exchangers are divided into plate heat exchangers, shell and tube heat exchangers, hybrid heat exchangers, etc., of which plate heat exchangers are more commonly used. They are heat exchangers that are separated by plates at a certain distance. Long-term use of the heat exchanger will cause more scale impurities to be attached to the plates, and thus requires professional cleaning equipment to align and clean them. Most cleaning devices on the market use high-pressure water guns to flush and clean the plates through the high-pressure impact force of water.

[0003] However, most of the existing heat exchanger cleaning devices on the market require a handheld water spray gun to wash the heat exchanger plates one by one. When a large number of heat exchanger plates need to be cleaned, the labor cost will be greatly increased, which is time-consuming and labor-intensive, and greatly reduces the work efficiency of cleaning the heat exchanger plates.
