Core rotation type shell-and-tube heat exchanger

Abstract

The invention relates to a shell-and-tube heat exchanger and particularly relates to the core rotation type shell-and-tube heat exchanger which comprises a shell body (4), wherein two ends of the shell body (4) are provided with a left seal head (1) and a right seal head (10), wherein the upper end of the left seal head (1) is provided with a tube pass outlet connecting pipe (2), the lower end of the right seal head (10) is provided with a tube pass inlet connecting pipe (11), the upper end of the shell body (4) is provided with a shell inlet connecting pipe (3),the lower end of the shell body (4) is provided with a shell pass outlet connecting pipe (12), a rotating heat transfer core (19) is installed inside the shell body (4), two ends of the rotating heat transfer core (19) are provided with revolving members (9), unprecedented perturbation is increased into the heat exchanger, dead zones which exist possibly are eliminated, fluid velocity of some heat transfer areas is increased greatly, heat transfer dead areas in a diving wall type heat exchanger in the prior art are eliminated entirely, and convection current heat exchanging efficiency of the heat exchanger and heat transfer effect of the heat exchanger are improved remarkably.

Description

technical field [0001] The invention relates to a shell-and-tube heat exchanger, in particular to a core-rotating shell-and-tube heat exchanger. Background technique [0002] At present, shell and tube heat exchangers are widely used in energy, power, petrochemical and other industries. With the emergence of energy crisis, the improvement of energy utilization and conservation requirements makes it particularly important to improve the performance of heat exchangers. The existing enhanced heat transfer technology of the tube side of the shell-and-tube heat exchanger mainly increases the degree of fluid turbulence and expands the heat transfer area by changing the shape characteristics of the heat transfer surface or adding inserts in the tube, so as to achieve enhanced heat transfer and achieve Energy saving purpose. Nevertheless, there is still much room for improvement in the heat exchange effect of the shell-and-tube heat exchanger. Many of the shell-and-tube heat exchan...

Problems solved by technology

Nevertheless, there is still much room for improvement in the heat exchange effect of the shell-and-tube heat exchanger. Many of the shell-and-tube heat exchangers have a poor heat exchange effect in the center of the heat exchange tube, and there are flow dead ends at the connection between the baffle and the shell. Area, serious fouling needs to be cleaned frequently or the heat exchange effect is not ideal although there is no dead zone
