Description

Technical Field

[0001] The present invention relates to the technical field of electrochemical water treatment equipment, and particularly to an electrochemical water treatment equipment with continuous scale removal and high-efficiency sterilization functions. Background Art

[0002] Electrochemical water treatment technology refers to a technical process in which, under the action of an externally applied electric field, in a specific electrochemical water treatment device, through a series of designed chemical reactions, electrochemical processes or physical processes, a large number of free radicals are generated, and then the strong oxidizing property of the free radicals is used to degrade pollutants in wastewater.

[0003] At present, there are still some deficiencies in the existing electrochemical water treatment devices: 1. In the existing electrochemical water treatment device, a cathode plate and an anode plate are installed inside. A direct current is provided by a direct current power supply, with the positive pole connected to the anode plate and the negative pole connected to the cathode plate for electrochemical reactions. However, during the reaction process, due to the generation of a large amount of OH - on the cathode, in the presence of OH - , it is very easy for insoluble substances such as CaCO3↓ and Mg(OH)2 to adhere to the surface of the cathode plate, forming a scaling layer, and the scaling layer will seriously affect the normal reaction of the cathode plate, reducing the treatment efficiency and quality.

[0004] 2. Currently, the electrochemical water treatment equipment in use usually also needs to be equipped with a combined treatment of bactericidal agents, which is very easy to produce residues or secondary pollution, and the sterilization effect is not ideal. Summary of the Invention

[0022] Among them, the high-efficiency pulse power supply is connected to the high-efficiency chlorine-evolving columnar anode through a cable, and the high-frequency power supply is connected to the cathode plate through a cable.

[0023] Further preferably, the first anode is a chlorine-evolving columnar anode, and the second anode is a sheet anode.

[0024] Further preferably, 4 groups of first anodes are arranged between the first cathode plate and the second cathode plate close to the water inlet.

[0025] Further preferably, a fixing seat 13 is provided on the inner wall of the chemical reaction cylinder body, a slot is provided on the fixing seat, and a frame that is movably connected to the slot is provided on the outer ring of the cathode plate.

[0026] Further preferably, a sampling port is provided on the water inlet.

[0027] The descaling assembly includes a main drive shaft 101, a rotary drive device 102, an inclined surface slag scraping knife 103, and a tool holder 104. The main drive shaft is axially arranged in the chemical reaction cylinder body, and through holes allowing the main drive shaft to pass through are concentrically arranged on the cathode plates. One end of the main drive shaft passes through the cathode plate and extends to the chemical reaction cylinder body and is connected to the rotary drive device. Multiple groups of tool holders are arranged on the main drive shaft, and one group of tool holders corresponds to one cathode plate. Two inclined surface slag scraping knives are arranged on one tool holder, so that one inclined surface slag scraping knife is closely attached to the front surface of the cathode plate, and the other inclined surface slag scraping knife is closely attached to the back surface of the cathode plate. The length of the inclined surface slag scraping knife is greater than or equal to the radius of the cathode plate. When the main drive shaft rotates under the action of the rotary drive device, the two inclined surface slag scraping knives rotate axially driven by the main drive shaft to synchronously scrape the two surfaces of the cathode plate.

[0028] Further preferably, a set of inclined surface slag scraping knives can be provided on the tool rest, or two sets (with an included angle of 180°) or more inclined surface slag scraping knives can be provided. As Figure 4 shown, it is a schematic diagram of using two sets of inclined surface slag scraping knives.

[0029] Further preferably, the rotary drive device includes a drive motor, and the output end of the drive motor is directly or connected to the main transmission shaft through a speed reducer.

[0032] When the electrochemical water treatment equipment is in use, the water to be treated is first introduced into the chemical reaction cylinder body through the water inlet for treatment: direct current is provided by a DC power supply, the positive electrode is connected to the second anode, and the negative electrode is connected to the cathode plate for electrochemical reaction. An oxidation reaction occurs on the surface of the second anode, generating a large amount of active oxidation substances, such as OH - 、Cl - and O 3 、H2O2、Cl2、HClO and other substances (bactericides) for sterilization, algae removal and scale removal; at the same time, 4 high chlorine evolution rod-shaped anodes at the front end are connected to a pulse power supply, and an adjustable current is input, so that the 4 chlorine evolution anodes can generate up to 1 kg of chlorine gas and other hydroxyl radicals at most, to further increase the sterilization ability, and no additional chemicals need to be added.

[0033] Among them, since the substances (bactericides) generated in this application will flow into the water tank through the water outlet, the concentration of bactericides in the water tank can be monitored in real time by a detection device to adjust the current level of the pulse power supply of this application, so as to adjust the efficiency of the chlorine evolution rod-shaped anodes.

[0034] When after a certain service life or the treatment efficiency / effect is lower than the preset threshold, the descaling component is started: the main transmission shaft is driven to rotate at 3 - 5 r / min by a reduction motor, and the inclined surface slag scraping knives corresponding to each cathode plate on the main transmission shaft slowly scrape off the water scale on the cathode plate. The scraped water scale precipitates to the bottom of the chemical reaction cylinder body by its own gravity and is discharged through the sewage outlet.

[0035] The beneficial effects of an electrochemistry water treatment device with continuous scale removal and high-efficiency sterilization functions according to the present invention are as follows: It can not only effectively improve the performance and efficiency of sterilization, algae removal, and scale removal, save energy and reduce emissions, but also generate sterilizing substances by itself, without adding extra agents, which can save a lot of costs and is cleaner and more environmentally friendly.
