Description
Technical Field
The utility model belongs to the technical field of filtration equipment, in particular to intelligence electrochemistry scale removal device.
Background
The electrochemical descaling belongs to a novel high-tech technology encouraged by the state and is an effective means for gradually replacing or substituting the treatment of the circulating cooling water chemical dosing methodThe principle is that calcium and magnesium ions in weak alkaline environment water with pH of 9-13 are formed near an electrolytic cathode through an electrode group consisting of the cathode and the anode by utilizing the electrolytic technology to generate CaCO under the alkaline environment near the cathode3、Mg(OH)2And the like, thereby achieving the purpose of removing the hardness and alkalinity in water, namely reducing or avoiding the surface scaling of heat exchange equipment, improving the heat exchange effect, and simultaneously generating free chlorine, ozone and other substances which can sterilize and algae-killing under the action of current in the weakly acidic environment near the anode, so that the scale inhibition, corrosion inhibition, sterilization and algae-killing functions of chemical agents can be reduced or replaced by the electrolytic water descaling technology, the concentration multiple of circulating water is greatly improved, energy is saved, the environment is protected, the circulation multiple of water is improved, the wastewater discharge is reduced, no chemical agent is added, and the secondary pollution caused by the chemical agent is avoided. Cathode scaling of the electrolytic water descaling device needs to be removed in time in the operation process, otherwise, not only is the electrolytic voltage increased to reduce the descaling effect, but also the electrode short circuit is possibly caused to cause equipment damage and rejection, so that the cathode descaling directly influences the safe and economic operation of electrolytic water descaling, but the cathode descaling is very difficult due to the fact that the distance between the cathode and the anode of the electrolytic water descaling needs to be controlled within the range of 3-20cm and the electrode plate form. In addition, the water content of the dirt cleaned after descaling is very large, even reaches more than 90%, so that the dirt cleaned after descaling is only treated by a natural precipitation method, and the sediment treatment is difficult.
However, (1) the electrode group of the existing water electrolysis descaling device generally adopts a plate type structure, and the cathodes and the anodes are alternately arranged, so that the structure is compact, the occupied area is reduced, the equipment cost is reduced, the unit processing capacity can be improved, and the equipment maintenance and management are convenient. In fact, the cathode plate is not easy to remove after scaling in the electrolytic water descaling process, manual rapping or high-pressure water washing is generally needed after the cathode plate is dismantled, and the labor intensity is increased. The cathode is relatively difficult to remove and manually remove, so the manual removal time is determined by the scale deposition thickness of the cathode plate, and the manual removal is carried out when the scale deposition thickness of the cathode plate reaches a certain degree (generally to 20-50mm thickness). The electrode group adopting manual removal cannot be removed in time due to manual removal, the electrolytic voltage and the electrolytic current are affected when the cathode scaling reaches more than 3mm, the electrolytic voltage and the electrolytic current are gradually increased along with the increase of the cathode scaling thickness, the scaling capability is lower, and the energy consumption is increased.
(2) Part of the electrode group adopting the scraper type descaling mode only adopts plate electrodes, compared with a net type structure, the electrode descaling capacity of the plate structure is lower, the electrode spacing of the plate structure polar plate is generally 100mm, so that the electrolytic voltage and current are higher, and the energy consumption is increased. In addition, the scraper descaling mode has a good effect on soft scale attached to the polar plate, but has a poor effect on hard scale on the polar plate, so that the hard scale on the polar plate of the scraper descaling electrode can be gradually increased, the electrolytic voltage and current are also increased along with the extension of the running time, and the cathode needs to be periodically removed for manual removal.
(3) The electrode basket type electrolytic water descaling equipment only can increase the diameter of the electrode basket and increase the distance between electrode groups in order to use a scraper to replace manual scale scraping. The electrode basket type electrolytic water descaling equipment unit has small water treatment amount, and needs a plurality of pieces of equipment to run in parallel in order to increase the treatment amount, so that the equipment has high cost and large occupied area, the electrolytic voltage and current are high, and especially when the treatment amount of circulating cooling water is large, the unit equipment can not be used due to too much occupied area.
(4) The electrode group adopting the reversed electrode for cathode cleaning has good cleaning effect, but the cathode is changed into the anode when the electrode is reversed, so that an acid environment is caused near the polar plate, the polar plate is corroded, and the service life of the cathode is greatly shortened.
(5) The cleaning after the cathode scaling of the existing electrochemical descaling device adopts the mode of manual mechanical cleaning such as a rapping hammer and the like, which wastes time and labor, the water content of the dirt washed by adopting a high-pressure water gun washing mode is too large, and the dirt can only be treated by adopting a mode of natural sedimentation in a sedimentation tank, so that the automatic control cannot be realized.
The electrode group adopting the reversed electrode for cathode cleaning has good cleaning effect, but the cathode is changed into the anode when the electrode is reversed, so that an acid environment is caused near the polar plate, the polar plate is corroded, and the service life of the cathode is greatly shortened.
