Description

Technical field [0001] The invention belongs to the technical field of descaling, and specifically relates to a bipolar pulse descaling method and descaling device. Background technique [0002] The fouling problem of high-power central air conditioners, boilers, heat exchange equipment or pipes has always been a major problem that plagues people. The hard scale on the pipe wall of the heat exchange equipment will greatly reduce the parameters of the exchanger, and the fouling of the pipe will affect the flow of the system. , Therefore had to be cleaned. [0003] Existing cooling circulating water descaling generally adds scale inhibitors, corrosion inhibitors, and bactericidal algaecides to the circulating water, but the scale inhibitors and corrosion inhibitors do not reduce the concentration of scale-forming factor ions in the water, as the evaporation concentration of the cooling water As it gets higher and higher, the chemical method cannot avoid the formation of scale, and t...

AI Technical Summary

Problems solved by technology

[0002] The scale problem of high-power central air conditioners, boilers, heat exchange equipment or pipelines has always been a major problem for people. The hard scale on the tube wall of heat exchange equipment will greatly reduce the parameters of the exchanger, and the scale of the pipeline will affect the flow of the system. , and thus had to be cleaned

[0003] For descaling of existing cooling circulating water, scale inhibitors, corrosion inhibitors, and bactericides and algaecides are generally added to the circulating water, but the scale inhibitors and corrosion inhibitors do not reduce the ion concentration of scaling factors in the water. The scale is getting higher and higher, and the chemical method cannot avoid the formation of scale, and the final water change and discharge during cleaning will cause secondary pollution

[0004] Others, such as ultrasonic method, electronic descaling method, etc., have low conversion efficiency, and only change the crystal form of scale, and cannot reduce water hardness

[0005] There are also electrochemical treatment technologies such as direct current electrolysis, which have shortcomings such as excessively high voltage, unavoidable polarization effects, and electrolytic efficiency becoming lower and lower after electrode fouling and oxidation, and the overall descaling effect is not very obvious.
