Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water treatment, in particular to an electric pulse descaling device. BACKGROUND

[0002] The scaling problem of high-power central air conditioners, boilers, heat exchange equipment or pipelines has been a major problem that has plagued people. The hard scale on the wall of the heat exchange equipment can greatly reduce the parameters of the exchanger, and the scaling of the pipeline can affect the flow of the system, so that cleaning has to be performed.

[0003] The existing descaling of cooling circulating water generally adds scale inhibitors, corrosion inhibitors, bactericides and algae inhibitors to the circulating water, but the scale inhibitors and corrosion inhibitors do not reduce the concentration of scale-forming factor ions in the water. With the evaporation of the cooling water, the concentration becomes higher and higher, and the chemical method cannot avoid the formation of scale. Moreover, the final water change and cleaning cause secondary pollution; other methods such as ultrasonic and electronic descaling have low efficiency and can only change the crystalline form of scale, but cannot reduce water hardness; and the direct current electrolysis method of electrochemical treatment technology has the problems of high voltage and cannot avoid polarization effect, and the overall descaling effect is not very obvious.

[0004] In view of the above problems, the Chinese invention patent with the patent number CN103241844B discloses a bipolar pulse descaling method and a descaling device thereof, which uses safe low voltage for descaling, has high efficiency and low energy consumption, completely solves the problem of electrode polarization effect, and adds a negative potential collecting electrode outside the double electrodes, effectively adsorbs the main components of calcium, magnesium and other scale-forming substances, greatly enhances the descaling effect, does not cause secondary pollution, and also has the functions of rust removal, corrosion delay, sterilization and algae inhibition, effectively prolonging the service life of the equipment.

[0005] The bipolar pulse descaling scheme disclosed in the above-mentioned invention patent greatly enhances the descaling effect to a certain extent. The calcium, magnesium and other metal ions in the electrolyzed water react to form calcium silicate, magnesium carbonate, calcium hydroxide and magnesium hydroxide in the area of the collecting electrode, and are attached in the form of loose needle-shaped crystals; but manual cleaning is still needed frequently, otherwise the scale accumulation will be difficult to clean after hardening, which will affect the electrolysis and adsorption efficiency and seriously affect the use efficiency of the entire device.

[0006] In view of the problem that the electrode sheet needs manual participation for frequent cleaning of scale, the existing technology generally adopts the mode that the scraper driven by power is closely attached to the electrode sheet and regularly slides along the length direction or width direction of the electrode sheet to shovel off the scale on the electrode sheet (for example, the Chinese utility model patent with the patent number CN214457046U discloses a cooling circulating water treatment equipment, after the cooling circulating water enters the box reactor, the scaling ions in the cooling circulating water are precipitated under the electrolysis of the anode plate and the cathode plate, adhere to the surface of the cathode plate, and then the cleaning device with the main body of the scraper structure automatically cleans the scale adsorbed on the surface of the cathode plate, instead of manual cleaning of the scale, improves the work efficiency and reduces the labor burden of workers); in the use process of this mode, the damage to the electrode sheet and the scraper is large, and after a certain period of use, the wear of the two will easily lead to the increase of the difficulty of scale removal (the scale is more closely combined with the electrode sheet after the wear of the electrode sheet) and the reduction of the scale removal effect.

[0007] Therefore, there is a need for an electric pulse scale removal device which can automatically complete the scraping of scale on the electrode sheet, has less damage to the electrode sheet and the scraper during the scraping process, and has relatively strong scale removal effect. SUMMARY
