Problems solved by technology

[0003] In order to solve the problem of insufficient cleaning torque of the existing self-rotating plastic spiral bond in the heat transfer tube with a flow rate below 0.8m / s and the wear problem of the steel wire spiral cleaning technology, the present invention proposes a dirt cleaning plastic spiral device with enhanced heat transfer fluid power, The fast swirling flow formed by the tube-side liquid passing through the screw-type nozzle fixing device impacts the screw power wheel to significantly strengthen the rotation torque of the plastic screw, so that it can be transmitted at the medium and low flow rates of the largest number of 0.4m / s to 0.8m / s. Widely used in thermal equipment
At the same time, plastic is used to solve the wear problem between the steel wire helix and the heat transfer tube wall,

Abstract

Disclosed is a technology of automatic scale removal and scale prevention of plastic cladding helix or plastic helical band in a heat transfer tube by rotational vibration driven by hot fluid in the tube. The technical structure is simple, and is convenient for use.

Description

technical field [0001] The invention relates to a heat transfer fluid power enhanced dirt cleaning plastic screw device. It is suitable for all kinds of heat transfer equipment with shell and tube structure, such as descaling and anti-scaling in the tubes of heat exchangers, condensers, evaporators and other equipment, as well as heat transfer enhancement. Background technique [0002] Chinese patent ZL91213000.8 and literature (Experimental Research on Automatic Rotating Helical Heat Transfer Technology, Chemical Equipment Technology, 1997, N5, P4-8) reported a kind of steel wire helix in the heat transfer tube for descaling and anti-scaling and its heat transfer enhancement technology. Driven by the flow energy of the heat transfer liquid in the tube, the steel wire helix rotates by itself, scrapes the dirt on the inner wall of the tube, and has the function of online, automatic and continuous cleaning and anti-scaling; due to the diversion effect of the steel wire helix,...
