System for automatically cleaning inner pipe walls of heat exchanger

Abstract

The invention discloses a system for automatically cleaning inner pipe walls of a heat exchanger, and provides a technology used for cleaning dirt on the inner pipe walls of the heat exchanger. The system is characterized in that a plurality of opening dirt cleaning rings form dirt cleaning ring groups; two ends of each stainless steel wire for connecting the dirt cleaning ring groups in series are fixed on movable end plates arranged at two ends of the heat exchanger; the movable end plates are connected with a front push arm and a rear push arm at two ends through shafts; the push arms are fixed on a heat exchanger casing through brackets and drive all opening dirt cleaning ring groups by hydraulic pressure or other power to perform reciprocating motion, the push arms on two sides are started periodically to drive the end plates to perform reciprocating motion at a slow and constant speed, and the dirt cleaning ring groups also perform the reciprocating motion in pipes at the slow and constant speed to clean up dirt on the inner pipe wall surfaces. The system for automatically cleaning the inner pipe walls of the heat exchanger is convenient to operate, low in failure rate, small in investment and low in equipment cost and can perform full automatic operation, and further, the friction coefficient of the system is very small, so that the inner pipe walls cannot be damaged.

Description

Technical field: [0001] The invention is a technology applied to cleaning the inner pipe wall dirt of shell-and-tube heat exchange equipment, heat pump evaporators and condensers. The invention has the advantages of simple structure, low operating cost, small water resistance and low failure rate, and is especially suitable for occasions with active biological pollution sources. Background technique: [0002] With the rapid development and application of heat exchange equipment technology, the energy utilization rate has been improved. The successive development and application of various new and high-efficiency heat exchange equipment has produced huge social and economic benefits, but one of the important problems that still exists is the scaling problem on the inner wall of the tube. At present, the methods for dealing with scaling on the inner wall of heat exchanger tubes are as follows: 1. Improve the water quality of the water entering the equipment and strengthen the...

Problems solved by technology

These two methods of cleaning can only be carried out after the equipment is stopped, and both will cause varying degrees of damage to the inner wall of the tube, greatly reducing the effective operating time and service life of the equipment
