Technical Field

[0001] The utility model belongs to the technical field of heat exchangers, and in particular relates to a descaling device for a heat exchanger. Background Art

[0002] A heat exchanger is a device that transfers heat between fluids. It is widely used in processes such as heating, cooling, evaporation, and condensation. It allows the fluid to flow in a shell and exchange heat through tubes or plates. Heat exchangers are used in many industrial fields, such as petrochemicals, food and beverages, medicine, energy, etc.

[0003] During the use of the heat exchanger, water passes through the interior of the heat exchanger. The water contains dissolved minerals. When the water flows in the heat exchanger and is heated, its temperature rises and its solubility decreases, causing mineral ions to precipitate and deposit on the internal surface of the heat exchanger to form scale. The formation of scale will reduce the heat exchange efficiency of the heat exchanger, increase energy consumption, and may even cause equipment blockage and damage. In order to improve the heat exchange efficiency of the heat exchanger and increase the service life of the heat exchanger, the interior of the heat exchanger needs to be cleaned. A cleaning liquid will be introduced into the interior of the heat exchanger to clean the scale inside the heat exchanger with the cleaning liquid. The residue after cleaning is discharged from the interior of the heat exchanger with the water. When cleaning the heat exchanger, a large amount of water is needed, resulting in a waste of resources. The problem with the above technology is that a large amount of water is needed to clean the scale inside the heat exchanger, and the cleaned water contains large residues and cannot be recycled, resulting in a waste of resources.
