Description

Technical Field

[0001] The utility model relates to the technical field of heat exchanger equipment, in particular to a batch fine washing device for heat exchanger plates. Background Art

[0002] The plate heat exchanger is a high-efficiency heat exchanger made of a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between various plates, and heat is exchanged through the plates. The plate heat exchanger is an ideal equipment for liquid-liquid and liquid-steam heat exchange. It has the characteristics of high heat exchange efficiency, low heat loss, compact and light structure, small footprint, wide application, and long service life. However, during production and use, as time goes by, the surface of the heat exchanger plate is prone to scaling, which affects the heat exchange efficiency. Therefore, it is necessary to clean the plate heat exchanger.

[0003] Chinese utility model patent CN218847013U describes a device for cleaning plate heat exchanger plates, which uses a lifting roller mechanism to perform the first cleaning of the plate, and the operator uses a movable roller mechanism to perform a second cleaning of the corners or missed brushing places according to the first cleaning situation. This cleaning method can effectively avoid the situation of inadequate cleaning, but manual pushing is still required during the cleaning process, and only one-side cleaning can be performed at a time, and batch cleaning cannot be achieved, and the efficiency is average. In addition, Chinese utility model patent CN210718777U describes a structure for cleaning plate heat exchanger plates, by setting clamping columns on the left and right sides of the heat exchanger plate to clamp and fix the heat exchanger plate, and setting bristles and nozzles on the front and back sides of the heat exchanger plate to clean the heat exchanger plate. This plate heat exchanger plate can clean the plate by itself, and can clean the two side walls of the plate at the same time, which improves the cleaning efficiency to a certain extent. However, the bristles are of brush type, and the friction during cleaning is smaller than that of a roller brush, and the cleaning power is average. In addition, this structure is not equipped with a wastewater treatment device. If the wastewater is directly discharged, it is easy to cause environmental pollution.

[0004] Therefore, in view of the above problems, a heat exchanger plate batch fine washing device is proposed to solve the above problems. Utility Model Content
