Scale removing device for heat exchange pipe

Abstract

The invention discloses a scale removing device for a heat exchange pipe. The scale removing device comprises a cooling beam (2), a spray gun (3) and a spray nozzle (4), wherein the cross section of the cooling beam (2) is of a C-shaped tubular structure; the spray gun (3) is arranged in an internal chamber of the cooling beam (2) through a spray gun sleeve (1); and the spray nozzle (4) extends out of the cooling beam (2) through a C-shaped gap. According to the technical scheme, the spray gun can rotate in the cooling beam, and also can be moved by stepping; spraying particular mediums are sprayed on a heat exchanger full of dirt through the spray gun at a high speed for removing the scale, so as to achieve the purpose of efficiently removing the scale and improving the working efficiency of the heat exchanger, and as a result, the purpose of saving energy and reducing the consumption can be achieved; the spray gun is cooled through cooling water in the cooling beam, therefore, the problem that the spray gun cannot work with high efficiency due to excessive heat during running in a high temperature condition can be avoided.

Description

technical field [0001] The invention belongs to the technical field of heat exchange in industrial production, in particular to the heat exchange technology of metallurgical production. Specifically, the invention relates to a heat exchange tube descaling device. Background technique [0002] The heat exchange stations of metallurgical enterprises are frequently used, and the working environment of the heat exchange tubes is quite harsh, so that the heat exchange tubes will be covered by the dirt generated in the production within a short time. The compactness and adhesion of the dirt are very high. If the dirt is not cleaned for a long time, the heat exchanger will lose its function; the heat exchange efficiency of the heat exchanger will decrease rapidly and cannot meet the process requirements. In some cases, it will even seriously affect the use of subsequent equipment and increase potential risks. . Contents of the invention [0003] The invention provides a heat e...
