Heat exchanger with brushing function and convenient-to-replace cleaning ball

Abstract

The invention discloses a heat exchanger with a brushing function and a convenient-to-replace cleaning ball, and belongs to the technical field of heat exchangers. The heat exchanger is characterizedthat multiple columns of heat exchange pipes (101) are arranged in the radial direction of the heat exchanger (1), multiple brushing pipes (17) are arranged at the end, close to a water inlet tube, ofa distributing plate (21), the range of each brushing pipe (17) to the center of the distributing plate (21) is the same as the range from the heat exchange pipe (101) in the corresponding position of the brush pipe to the heat exchanger (1), and the brushing pipes (17) are allowed to in butt joint with the heat exchange pipes (101) one by one; a transparent pipe (27) is arranged between a cleaning ball flow returning pipeline and a water outlet end of the heat exchange pipe (101), a return ball valve (28) is arranged between the transparent pipe (27) and the cleaning ball returning pipeline,and a discharging valve (29) is connected with a water outlet end of the transmission pipe (29). The heat exchanger has the advantages that online cleaning of the heat exchanger is achieved by the heat exchanger with the brushing function and the convenient-to-replace cleaning ball, and the replacement of the cleaning ball is convenient.

Description

technical field [0001] The utility model relates to a heat exchanger with a flushing function for convenient replacement of cleaning balls, which belongs to the technical field of heat exchanger cleaning. Background technique [0002] The shell-and-tube heat exchanger, also known as the shell-and-tube heat exchanger, is a wall-type heat exchanger that uses the wall of the tube bundle enclosed in the shell as the heat transfer surface. This heat exchanger has a simple structure, reliable operation, and can be used in various Made of structural materials (mainly metal materials), it can be used under high temperature and high pressure, and is currently the most widely used type. [0003] Oil fields usually use shell-and-tube heat exchangers to recover geothermal energy in oil fields, so as to use geothermal heat to increase oil temperature, reduce oil viscosity, and facilitate oil transportation. Because the water in the oil field contains too much oil and impurities, when usi...

Problems solved by technology

[0003] Oil fields usually use shell-and-tube heat exchangers to recover geothermal energy in oil fields, so as to use geothermal heat to increase oil temperature, reduce oil viscosity, and facilitate oil transportation. Because the water in the oil field contains too much oil and impurities, it is necessary to There will be scale in the heat exchange tube of the shell and tube heat exchanger. The existence of scale will affect the heat exchange efficiency of the heat exchanger, hinder the flow of water through the heat exchange tube, and affect the use of the heat exchanger. Therefore, it is necessary to replace it regularly. The heat exchanger is cleaned, but in the existing cleaning process, it is necessary to stop using the heat exchanger before cleaning the heat exchanger, which affects the use of the heat exchanger, and because the cleaning cycle is short, it is necessary to stop the heat exchange frequently The use of the heat exchanger greatly affects the use of the shell-and-tube heat exchanger, and the cleaning is not thorough
