Description

Technical Field

[0001] The utility model relates to the technical field of descaling of reaction vessels, in particular to a descaling device for an electrolytic descaling reactor. Background Technique

[0002] An electrolytic descaling reactor electrolyzes circulating cooling water to precipitate calcium ions and magnesium ions in the water on the cathode surface in advance, and then uses a descaling mechanism to remove them, so as to reduce the hardness of the circulating cooling water, protect the heat exchanger and improve the heat exchange efficiency. The electrolytic descaling reactor assembly mainly includes: an anode, a cathode, a descaling motor, inlet and outlet valves, a sewage discharge valve, a control system, a motor bracket and a descaling mechanism. When the circulating cooling water passes through the electrolytic descaling reactor, the cathode releases electrons to form a high-concentration hydroxide ion solution. This environment with a high pH value of about 13 causes calcium and magnesium ions in the water to precipitate out of the water and form water-insoluble crystals adsorbed on the inner wall of the cathode of the electrolytic reaction chamber. Then, removing the crystals completes the descaling process.

[0003] The existing Chinese utility model patent with the reference publication number of CN206529316U discloses a descaling device for an electrolytic descaling reactor. The descaling device uses a brush cage skeleton made of plastic material to avoid metal corrosion, and the detachable strip brush assembly facilitates the replacement of the strip brush. The brush cage skeleton is continued to be used, saving the use cost; a positioning tension bar is used to connect the bottom frame and the upper frame into an integrated brush cage skeleton structure; and a plurality of tension bar installation grooves are uniformly arranged along the circumferential direction of the frame ring, and the positioning tension bars are correspondingly installed to support the formed brush cage skeleton; the positioning tension bar and the frame ring are welded and fixed by a hot-melt material to form a stable brush cage skeleton structure, providing a basis for the installation of the strip brush assembly and also facilitating the long-term use of the brush cage skeleton.

[0004] When the above-mentioned descaling device is in use, it can only be cleaned in one direction, so that the dirt on the inner wall of the reaction chamber is not convenient to be fully cleaned. Moreover, when the cleaning brush plate is disassembled and assembled, special tools are required, which is rather inconvenient. Therefore, those skilled in the art provide a descaling device for an electrolytic descaling reactor to solve the problems raised in the above background technique. Content of the Utility Model
