Micro-channel heat exchange process and equipment

Abstract

The invention relates to the technical field of micro-channel heat exchange, and discloses a micro-channel heat exchange technology and equipment which comprises a first working table plate, box body supporting legs are fixedly connected to the top of the first working table plate, a box body is fixedly connected to the tops of the box body supporting legs, and a first pipeline fixedly penetrates through one side of the box body. Through the arrangement of the heat dissipation device, a first valve is opened and closed to enable hot liquid to flow into the heat dissipation device from a first pipeline, a third valve is opened to enable cold liquid to flow into a third channel pipe to flow into the heat dissipation device, the problems that traditional mechanical equipment cannot dissipate heat of liquid, safety accidents are prone to occurring are solved, and the effects of mechanical heat dissipation and stable and safe production are achieved.

Description

technical field [0001] The invention relates to the technical field of microchannel heat exchange, in particular to a microchannel heat exchange process and equipment. Background technique [0002] The casing heat exchanger is currently the most widely used heat exchanger in petrochemical production. It is mainly composed of shell (including inner shell and outer shell), U-shaped elbow, stuffing box and so on. The required pipes can be made of ordinary carbon steel, cast iron, copper, titanium, ceramic glass, etc. The tubes are generally secured to supports. Two different media can flow in the opposite direction (or in the same direction) in the tube to achieve the purpose of heat exchange. When performing reverse heat exchange, hot fluid enters from the upper part, while cold fluid enters from the lower part, and heat is transferred from one fluid to the other through the inner tube wall. The distance that the hot fluid flows from the inlet end to the outlet end is call...

AI Technical Summary

Problems solved by technology

The distance that the hot fluid flows from the inlet end to the outlet end is called the tube side. The fluid enters through the connecting pipe of the shell and is introduced from one end of the shell to the other end. The heat exchanger that transfers heat in this way is called Shell-side casing heat exchangers; currently, casing-type heat exchangers are widely used in petrochemical, refrigeration and other industrial sectors on the market; at present, researchers at home and abroad have proposed many improvement schemes for casing-type heat exchangers. In order to prolong the service life of the tubular heat exchanger, the maintenance, cleaning and disassembly of the tubular heat exchanger are troublesome now. Therefore, a microchannel heat exchange process and equipment are needed
