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

Embodiment 1

[0042] Such as Figure 1~2 As shown: the heat exchanger 1 is a cylindrical shape with closed ends, the heat exchanger 1 is arranged horizontally, and a plurality of heat exchange tubes 101 are arranged at intervals in the heat exchanger 1, and both ends of the heat exchange tubes 101 extend out to exchange heat At the corresponding end of the heat exchanger 1, the heat exchange tube 101 is arranged parallel to the axis of the heat exchanger 1, and a plurality of fins are arranged at intervals along the axial direction in the heat exchanger 1. The fins are semicircular, and the heat exchange tube 101 passes The fins are fixedly connected with the heat exchanger 1, which facilitates the installation of the heat exchange tube 101, increases the heat exchange area, and improves the heat exchange efficiency. Both ends of the heat exchanger 1 are provided with flanges coaxially.

[0043] A water inlet tube is coaxially installed at the left end of the heat exchanger 1, and an end of th...

Embodiment 2

[0055] Such as Figure 8~11 As shown, the difference between embodiment 2 and embodiment 1 is that the heat exchange tubes 101 in the heat exchanger 1 are arranged in multiple rows at intervals, and each row is provided with multiple heat exchange tubes 101 at intervals along the radial direction of the heat exchanger 1. . Only a distribution plate 21 is provided in the transition cylinder 3, and a plurality of scouring tubes 17 are provided on the distribution disk 21. The scouring tubes 17 are provided at one end of the distribution disk 21 close to the heat exchanger 1. The number of scouring tubes 17 is related to the number of scouring tubes 17 in each column. The number of heat exchange tubes 101 is equal, and the distance between each flushing tube 17 and the center of the distribution plate 21 is equal to the distance between the corresponding heat exchange tube 101 in each column and the center of the heat exchanger 1. The side of the distribution plate 21 is provided...

Abstract

A heat exchanger with a disc flushing device 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). The tubes (17), the flushing tubes (17) correspond to the heat exchange tubes (101) one by one and are arranged coaxially with the corresponding heat exchange tubes (101), and the pushing mechanism is connected with the flushing chambers (16) one by one and pushes them to translate; The mechanism includes a feed motor (4), a conversion motor (5), a screw (11) and a cam (19). The output shaft of the feed motor (4) is connected to the screw (11) and drives the screw (11) to rotate synchronously, and the conversion The output shaft of the motor (5) links to each other with the cam (19) and drives the cam (19) to rotate. The heat exchanger with the disc flushing device realizes the online cleaning of the heat exchanger without hindering the use of the heat exchanger.

Description

Technical field [0001] A heat exchanger with a disc flushing device belongs to the technical field of heat exchanger cleaning. Background technique [0002] Shell-and-tube heat exchanger, also known as tube-and-tube heat exchanger, is a partition type heat exchanger with the wall of the tube bundle enclosed in the shell as the heat transfer surface. This kind of heat exchanger has a simple structure and reliable operation. It is made of structural materials (mainly metal materials) and can be used under high temperature and high pressure. It is currently the most widely used type. [0003] Oilfields usually use shell-and-tube heat exchangers to recover the geothermal energy of the oilfield, so as to use geothermal heat to increase oil temperature, reduce oil viscosity, and facilitate oil transportation. Because the water at the oilfield site contains too much oil and impurities, it is used during use. There will be scale in the heat exchange tubes of the shell-and-tube heat exchan...
