EHT (Extra High Tension) self-cleaning energy-saving environment-friendly device and manufacture method thereof

Abstract

The invention relates to an EHT (Extra High Tension) self-cleaning energy-saving environment-friendly device for strengthened heat transfer and descaling in a heat exchange pipe and a manufacture method thereof. The device comprises rotors, a rotating shaft, stoppers and hangers, wherein the plurality of rotors are fixed on the rotating shaft at segments, 2-200 rotors are arranged at each segment, rotors which are limited at each segment have the total length of 100-2000 mm, the rotating shaft is a flexible soft shaft, and the difference between the outside diameter of each rotor blade and the inside diameter of the heat exchange pipe is from 0.1 mm to 3 mm. The manufacture method comprises the following steps of: firstly, respectively manufacturing the rotors, the rotating shaft, the stoppers and the hangers; then, mounting the rotors on the rotating shaft segmentally; limiting the rotors with the stoppers at the tail ends of the rotors at each segment; penetrating the rotating shaft with the rotors into the heat exchange pipe; mounting the hangers at both ends of the heat exchange pipe; and fixing the rotating shaft on the hangers through the stoppers. The EHT (Extra High Tension) self-cleaning energy-saving environment-friendly device and the manufacture method thereof have the advantages of wide sphere of applications, remarkable strengthened heat transfer and descaling effects, convenient counting and measuring, high mounting efficiency and convenient and simple operation.

Description

technical field [0001] The invention relates to a device for enhancing heat transfer and anti-fouling and decontamination in heat exchange tubes of equipment such as shell-and-tube heat exchangers, heat exchange reactors, condensers, and evaporators. , particularly relates to a device and a manufacturing method for installing and fixing interpolation elements in sections, limiting positions, improving heat transfer enhancement, and anti-scaling and descaling effects. Background technique [0002] Energy saving and emission reduction in today's society is a key technology that the whole world attaches great importance to, especially in many fields such as petroleum, chemical industry, thermal power, nuclear power, metallurgy, light industry, aviation components, and ship vehicles. Many heat exchangers are applied Among them, the shell and tube heat exchanger is the most widely used, but the inner wall of these heat exchange tubes generally has layered dirt, which leads to an ...

AI Technical Summary

Problems solved by technology

Several self-rotating rotors are installed on the rotating shaft, and when the rotor is fixed in the axial direction, the device does not optimize the structural characteristics, performance parameters, arrangement of the rotors, structure of the fixing frame, etc., and it is difficult to achieve a more satisfactory Enhanced heat transfer and anti-scaling and descaling effects
