An inner tube spinning type purification and thermal conduction reinforced spiral -curved tooth tube

Abstract

A inner tube rotating type purification and heat transfer reinforcement plastic helical tooth tube, wherein free rotating plastic helical tooth tube can be arranged in the heat transfer tube, whose inner chamber is stuffed by liquid or balls having good fluidity and an same integral density as that of the heat-transfer fluid in the tube, thus keeping the suspended state constantly. The tube by the invention effective reinforces the convective heat transfer, the heat transfer coefficient is increased by over 55%, thus can be widely used in the automatic purification and scale prevention for various type of low flow rate column tubes type heat transfer equipment.

Description

technical field [0001] The invention relates to a plastic spiral tooth tube with self-rotating cleaning and enhanced heat transfer in the tube. It is suitable for various heat transfer equipment with shell and tube structure, such as heat exchanger, condenser, evaporator, etc. 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, the steel wire spiral rotates under the drive of the flow energy of the heat transfer liquid in the tube, 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 spiral, the liquid flows in a spiral line and the steel wire The spiral has a disturbing...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is the wear problem existing in the above-mentioned self-rotating steel wire helical line cleaning technology and the problem that the low flow rate (in the range of 0.2m / s-0.7m / s) heat transfer equipment is difficult to apply. The plastic helical tooth tube with enhanced cleaning and heat transfer will not wear the heat transfer tube wall, but also double the rotation cleaning torque, which can be widely used in low flow rate heat transfer equipment
