Tube plate installation structure of quick-connection shell-and-tube heat exchanger

Abstract

The invention relates to a tube plate installation structure of a quick-connection shell-and-tube heat exchanger, and belongs to the field of a heat exchanger which is universally used in the chemical industry, the petroleum, the power, the food and other industrial departments. A main realization method is as follows: a single heat exchanging tube nest port is internally provided with connection threads and additionally provided with a connection solenoid cap, the solenoid cap is a hollow solenoid, the connection solenoid cap is externally provided with threads which are symmetric to the threads inside each single heat exchanging tube nest port, and the end part is provided with a cap body. The quick connection structure is characterized in that each single heat exchanging tube nest port presses a tube plate, the connection solenoid cap penetrates through the tube plate, the outer threads are screwed with the inner threads inside the heat exchanging tube nest, the cap body presses the tube plate, a hollow pipeline is connected with the heat exchanging tube nest, the heat exchanging fluid medium can conveniently pass through, thus a plurality of heat exchanging tube nests are effectively connected with the tube plate, the welding difficulty can be avoided, and a single tube nest is easy to replace.

Description

Technical field: [0001] The utility model relates to a tube plate installation structure of a quick-connected tube and tube heat exchanger, which belongs to the field of heat exchanger equipment commonly used in chemical industry, petroleum, power, food and other industrial sectors. Background technique: [0002] Heat exchangers are widely used in chemical, petroleum, power, food and other industrial sectors. As general equipment, traditional tubular heat exchangers mostly use heat exchange tubes, which are welded to the tube sheet. Two different The medium flows from the inside of the tube and the outside of the tube to exchange heat. Since the heat exchange tubes need to be intensively welded on the heat exchange tube plate, sometimes even thousands of them, so if these solder joints are welded or desoldered, it will affect the use of the equipment. , and the detection and replacement of a single heat exchange tube is also inconvenient.
