Improved capillary tube heat exchanger

Abstract

The invention discloses an improved capillary tube heat exchanger and relates to the technical field of heat exchangers. The improved capillary tube heat exchanger comprises a heat exchange box. The top of the heat exchange box is connected with a box cover through bolts in a sealing mode. According to the improved capillary tube heat exchanger, filtered heat exchange liquid is delivered into an annular pipeline along a connecting pipeline and flows down along hollow holes; impact force of heat exchange liquid on capillary heat exchange tubes can be reduced, and the travel distance of the heatexchange liquid in the heat exchange box can be increased, so that heat exchange is carried out more thoroughly. Meanwhile, the heat exchange liquid flows in the heat exchange box to continuously scour floating supports to drive scale removing sleeves to slide up and down along the capillary heat exchange tubes so as to clean water scale adhering to the surfaces of the capillary heat exchange tubes. The improved capillary tube heat exchanger can wash out the surfaces of the capillary heat exchange tubes all the time during heat exchange and effectively prevent the situation that much water scale coagulates to the surfaces of the capillary heat exchange tubes and reduces the heat exchange effect, the service life of the heat exchanger is prolonged, and the heat exchange efficiency of the heat exchanger is improved.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to an improved capillary heat exchanger. 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, petroleum, power, food and many other industrial productions. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc., and are widely used . In the partition wall heat exchanger, two fluids with different temperatures flow in the space separated by the wall, through the heat conduction of the wall and the convection of the fluid on the wall surface, heat exchange is performed between the two fluids. Partitioning wall heat exchangers include shell and tube, casing and other types of heat exchangers. Partitioning wall heat exchanger is currently the most widely used heat...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the existing technology, the present invention provides an improved capillary heat exchanger, which solves the problem that because the capillary heat exchanger has a large contact area with the heat exchange liquid, scale is extremely easy to adhere to the surface after a long time of use, which affects the heat exchange effect. , needs to be cleaned frequently, and the capillary heat exchange pipe itself has low strength. When in use, it is easy to bend or even break under the washing of high water flow, which limits its scope of use.
