Online cleaning device for cooler

Abstract

The invention provides an on-line cleaning device for a cooler. The on-line cleaning device comprises a backflow mechanism, a storage mechanism and a supply mechanism which are connected in sequence,the backflow mechanism is connected with a water return pipeline of the cooler, and the supply mechanism is connected with a water inlet pipeline of the cooler. When the cooler needs to be cleaned, awater inlet valve in the water inlet pipeline and a water return valve in the water return pipeline are closed, a feeding valve and a feeding pump 7 in the supply mechanism and a material return valvein the backflow mechanism are opened, cleaning liquid in the storage mechanism is promoted to form closed circulation between the cooler and the storage mechanism, water scale in the cooler is removed, and the reacted medicine liquid and the water scale are discharged through a discharging hole. According to the on-line cleaning device, the cooler does not need to be dismounted, online cleaning is achieved, the device is simple and efficient, and stable operation of a unit is not affected.

Description

technical field [0001] The invention relates to an online cleaning device for a cooler, which belongs to the technical field of heat exchange and cooling. Background technique [0002] In the normal production process of the power plant, there are strict standards for the temperature control of various working fluids. In order to meet the requirements of the production process, it is necessary to add heat exchange devices, oil coolers for the oil system, water ring vacuum pumps and closed The cooling device for desalinated water is used to control the temperature of various media through the countercurrent and downstream exchanges of cold and hot media. [0003] Since the cooling water of the cooler comes from circulating water, scaling on the water side of the cooler gradually occurs in the later stage of operation, resulting in a decrease in the flow area of ​​the water side, an increase in the end difference of the cooler, and poor cooling effect, which cannot meet the ne...

AI Technical Summary

Problems solved by technology

The following problems will occur during the dismantling and cleaning process: During the dismantling and cleaning of the cooler, the system has no spare equipment. Once there is a problem with the operating equipment, the spare cooler cannot be cut into the system in time for operation, which will bring hidden dangers to the stable operation of the unit; the existing power plant Most of the coolers in the country use plate coolers. The plate coolers have strict requirements on the installation process during disassembly and assembly. After reassembly, internal leakage between the heat exchange media is prone to occur. On the other hand, disassembling and cleaning the cooler will cause the cooler The gasket between is damaged, increasing the maintenance cost
