Abstract

The utility model relates to a heat exchanger with a fork type flushing device, which belongs to the technical field of heat exchanger cleaning. It is characterized in that: there are multiple flushing chambers (16) spliced ​​into a ring coaxial with the heat exchanger (1), and each flushing chamber (16) is provided with a plurality of flushing chambers (16) on the side close to the heat exchanger (1). Tubes (17), flushing tubes (17) are in one-to-one correspondence with the heat exchange tubes (101) and coaxially arranged with the corresponding heat exchange tubes (101). The pressure of the liquid in the heat exchange tube (101) is greater than the pressure of the liquid in the heat exchange tube (101); the water inlets (20) of the multiple flushing chambers (16) are respectively connected to the water outlet of the delivery pump (8) through the water inlet pipe (7), and the flushing chamber ( 16) A fixed ring (6) is arranged on the outside, and the water inlet pipe (7) is installed on the fixed ring (6) at intervals. The heat exchanger with the fork-type flushing device realizes the online cleaning of the heat exchanger without hindering the use of the heat exchanger.

Description

technical field

[0001] The utility model relates to a heat exchanger with a fork type flushing device, 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 using There will be scale in the heat e...
