Tubular heat exchanger

Abstract

A tubular heat exchanger belongs to the field of heat exchangers and comprises a shell and a shell cover, a heat source inlet and a heat source outlet are formed in the shell, a cold source inlet and a cold source outlet are formed in the shell cover, a vertical tube plate is arranged in the shell, a horizontal first partition plate is fixedly mounted on one side of the tube plate, and a second partition plate is fixedly mounted on the other side of the tube plate. Two transverse circular grooves, a connecting groove and a connecting hole are formed in the shell, the heat source inlet and the heat source outlet are communicated with the right sides of the corresponding circular grooves respectively, and the two circular grooves are communicated through the connecting hole. Compared with an existing U-shaped tubular heat exchanger, firstly, the U-shaped tubular heat exchanger is provided with the connecting grooves, the heat exchange tubes on the upper side are communicated with the heat exchange tubes on the lower side, only the straight tubes need to be cleaned during cleaning, and the problem that a U-shaped pipeline in an existing device is difficult to clean through a high-pressure water gun is solved; a user can detach the heat exchange pipe and the first spiral shaft to clean and maintain the heat exchange pipe and the first spiral shaft.

Description

technical field [0001] The invention belongs to the field of heat exchangers, in particular to a shell and tube heat exchanger. Background technique [0002] In recent years, my country's energy industry has vigorously strengthened the research on energy-saving technologies, and has continuously achieved new results in energy conservation and consumption reduction. As a high-efficiency heat transfer device that can transfer more heat in a smaller area, heat pipes have been widely used in various fields. Heat pipes not only have higher heat transfer efficiency than traditional materials, but also have the characteristics of compact structure, small mass, low noise, and no transmission components. It plays an important role; the U-shaped tube heat exchanger is a kind of tube-and-tube heat exchanger. The heat exchanger bends the heat exchange tube into a U-shaped structure to reduce the space occupied by the heat exchange tube. In addition, The heat exchange tubes of the heat...

Problems solved by technology

Heat pipes not only have higher heat transfer efficiency than traditional materials, but also have the characteristics of compact structure, small mass, low noise, and no transmission components. It plays an important role; the U-shaped tube heat exchanger is a kind of tube-and-tube heat exchanger. The heat exchanger bends the heat exchange tube into a U-shaped structure to reduce the space occupied by the heat exchange tube. In addition, The heat exchange tubes of the heat exchanger can expand freely, and cleaning by high-pressure water gun is the most commonly used cleaning method for the heat exchange tubes of the tube-and-tube heat exchanger. The cleaning cost is low, but the heat exchange tubes of the U-shaped tube heat exchanger It is difficult to clean with a high-pressure water gun, and the cleaning effect is poor. When cleaning, the U-shaped pipe fittings will change the direction of the high-pressure water flow, causing the high-pressure water flow to rush to the cleaner, which poses a safety hazard. In addition, the baffle plates of the existing heat exchanger are staggered up and down. distribution, when the heat exchanger stops exchanging heat, there will still be heat source liquid remaining between the lower baffles and cannot be discharged
