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

Abstract

A heat exchanger with a flushing function belongs to the technical field of heat exchanger cleaning. It is characterized in that: the heat exchange tubes (101) are arranged in multiple rows along the radial direction of the heat exchanger (1), and the number of heat exchange tubes (101) contained in each row is equal, and the flushing tubes of the distribution plate (21) The number of (17) is equal to the number of heat exchange tubes (101) contained in each column, and the distance from each flushing tube (17) to the center of the distribution plate (21) and the corresponding position of the heat exchange tubes (101) to The distance between the center of the heat exchanger (1) is equal, and the side of the distribution plate (21) is provided with a water inlet (20) corresponding to the flushing pipe (17) one by one, and the pushing mechanism is connected with the distribution plate (21) and drives the distribution plate (21) MOVEMENT. The heat exchanger with flushing function realizes the online cleaning of the heat exchanger, which is convenient and thorough, ensuring the heat exchange efficiency of the heat exchanger, and the cleaning of the heat exchange tubes will not hinder the use of the heat exchanger .

Description

technical field [0001] A heat exchanger with a flushing function 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 using There will be scale in the heat exchange tube of the shell and tube heat exch...
