Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of heat exchanger scaling cleaning, in particular to a heat exchanger scaling cleaning device. Background Art
[0002] The main reasons for the scaling and blockage of the heat exchanger tube bundle are that the total hardness, calcium hardness, concentration ratio and conductivity of the cooling water exceed the standard, and the scale, sludge, oil, dust and other coverings gather on the tube bundle. If the above problems are not effectively controlled in time, then the scaling of the heat exchanger tube bundle will become worse and worse in a long and certain operation cycle, and eventually lead to complete blockage of some tube bundles, which will seriously threaten the safe and stable operation of the unit. Therefore, when the heat exchange tube bundle is completely blocked, how to clear the tube bundle in time with the shortest maintenance time, the least maintenance personnel input and the most labor-saving method, so that the equipment can be put into operation quickly, is a difficult problem to be solved in the maintenance work;
[0003] In the prior art, it is difficult to clean the inner wall of the heat exchanger and the outer side of the pipe when in use, and the staff needs to clean it manually. The inner wall of the pipe needs to be unblocked by a drill bit, and the drill bit can only clean the pipes one by one, which makes the working time longer and the working efficiency lower. Therefore, we propose a heat exchanger scaling cleaning device. Utility Model Content
