A machine for cleaning the inner wall of heat exchanger tubes, using a mobile cleaning device inside the tubes.

Abstract

Page 1 of 1 Summary of the invention. A machine for cleaning the inner walls of heat exchanger tubes, using a mobile cleaning device. Inside the pipe It is an invention that can be modified from existing heat exchangers, including the drive system. Using condensate minimizes the risk of contamination to the product. Cleaning devices use metal in the form of twisted discs or shaped like bottle brushes, with a specific diameter. The outer diameter is smaller than the inner diameter of the heat exchanger tube and its length is approximately the same as the tube length. It is inserted into the tube. 1. Heat exchangers are located throughout the pipes, and they operate continuously during use. This invention improves the heat transfer efficiency of shell & tubular heat exchangers. Tubes maintain high efficiency at all times, resulting in increased product production, reduced cleaning downtime, reduced chemical usage, and... The amount of water used is reduced due to decreased downtime and less damage to heat exchanger tubes from cleaning the equipment. Mechanical It can be used with both vertical and horizontal shell and tube heat exchangers at various speeds. Flow rate not exceeding 1.5 meters / second. Suitable for all types of products with high viscosity or high levels of impurities. (The images used for publication are Figures 3, 4, and 7.)
