A fast heat exchange device for chemical industry

Abstract

The invention discloses a quick heat exchange device used in the chemical industry. The quick heat exchange device comprises a box body and a base, wherein a PLC is arranged on one side of the box body; a first baffle is arranged in the box body; two groups of temperature monitors which are distributed in a symmetric manner are arranged on the two sides of an electromagnetic valve separately; two groups of third air guide pipes which are distributed in a symmetric manner are arranged on the two sides of the box body separately; more than twenty two fourth air guide pipes are arranged between the third air guide pipes and the box body; the ends, close to the box body, of the fourth air guide pipes extend into the box body and are connected with each of the first baffle and a second baffle; and a steam electromagnetic valve is arranged at one end of each of the third air guide pipes. The quick heat exchange device used in the chemical industry has the benefits as follows: the electromagnetic valve is arranged on the first baffle and the second baffle, mixing heat exchange is realized, through the design of a steam box, both preheating and quick heat exchange are realized, the steam electromagnetic valve is arranged at one end of each of the third air guide pipes, so that the safety of the heat exchanger is improved, the heat exchange efficiency is increased, the size is small and the operation is simple and convenient.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a rapid heat exchange device for chemical industry. Background technique [0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger. Heat exchangers play an important role in chemical, power, food and many other industrial productions. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers. They are widely used in Higher heat exchange efficiency is usually required during use. For example, the patent application publication number CN 105509516 A discloses a rapid heat exchange device for chemical industry. , the extension edge and the top of the vertical pipe body are welded and fixed on the inner side wall of the stepped through hole, the lower end of the vertical pipe body has a connecting small-diameter pipe, which is connected to the sma...

Heat exchangers play an important role in chemical, power, food and many other industrial productions. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers. They are widely used in Higher heat exchange efficiency is usually required during use. For example, the patent application publication number CN 105509516 A discloses a rapid heat exchange device for chemical industry. , the extension edge and the top of the vertical pipe body are welded and fixed on the inner side wall of the stepped through hole, the lower end of the vertical pipe body has a connecting small-diameter pipe, which is connected to the small-diameter pipe sleeve and clamped in the connecting through-hole. The outer wall of the diameter tube is welded and fixed on the inner wall of the connecting through hole, but the above patents cannot achieve mixed rapid heat exchange and preheating during use, the function is too single and simple, and the heat exchange efficiency is low
