Problems solved by technology

Pitting corrosion of the pipe fittings will cause the equipment to fail to meet the design and use requirements, and it will be repaired or even scrapped in advance. At the same time, there will be safety hazards; coking and fouling will lead to a decrease in the efficiency of mass transfer and heat transfer of the equipment, and increase energy consumption.
[0003] In the prior art, for pipe fittings products in confined spaces, especially large-scale equipment, the inner surface of pipe fittings with a length of more than several meters is electrochemically treated, and the anode current is limited by the material, length, electrolyte, and distance between the electrode wire and the cathode and other factors, resulting in uneven distribution of internal current in the product and affecting product quality

Abstract

The invention provides an in-tube electrolytic brush head device which comprises a device main body (1), a graphite sliding block (2) and a spring (3), and is characterized in that the device main body (1) is a hollow tube body, a sliding block mounting hole (10) is formed in the surface of the tube body of the device main body (1), the spring (3) is connected with the graphite sliding block (2), and the graphite sliding block (2) is embedded in the sliding block mounting hole (10) of the device main body (1). The specially designed anode is used for electrolyzing the inner wall of the long tube section by section; the anode structure is changed, and current loss and non-uniformity caused by the length of the to-be-treated pipe fitting are reduced; and a stepping mode is adopted, so that the power-on time can be effectively controlled, and the surface quality uniformity of the product is ensured. The method is small in product size limitation, simple in construction, small in investment and convenient for quality control.

Description

technical field [0001] The invention relates to the field of anti-corrosion, in particular to an electrolytic brush head device in a tube. Background technique [0002] In petrochemical refining units, many parts use pipes, such as heat exchangers. In practical applications, corrosion and coking fouling will appear on the inner surface of the pipe fittings. Once the pitting corrosion occurs in the pipe fittings, the equipment will not meet the design requirements, and it will be repaired in advance or even scrapped, and there will be potential safety hazards. [0003] In the prior art, for pipe fittings products in confined spaces, especially large-scale equipment, the inner surface of the pipe fittings with a length of several meters or more is electrochemically treated, and the anode current is limited by the material, length, electrolyte, and cathode of the electrode wire. and other factors, resulting in uneven distribution of current within the product and affecting pr...
