The invention relates to the technical field of electrochemical water treatment, in particular to electrochemical water treatment equipment.
Background
At present, for industrial circulating water treatment systems in China, water quality stabilizing agents are generally added to improve the concentration multiple of the circulating water system, so that the water supplementing amount of new water and pollution discharge treatment are reduced. Traditional water quality stabilization agents mainly include: corrosion inhibitors, scale inhibitors, bactericides and the like for controlling scale formation and corrosion of pipelines and equipment in a circulating water system have the following problems in addition to high cost of medicaments for water quality treatment and high running cost every year: (1) The chemical agent is used in a large amount, and the environment is polluted in the transportation and storage processes; (2) The medicament itself can form suspended matters and precipitates in a circulating water system to pollute the quality of the circulating water; (3) After the medicament is added, the conductivity of the circulating water system is increased, and the pollution discharge of the system is accelerated; (4) The sewage contains water treatment agent, and secondary pollution can be generated to the environment along with the discharge of industrial sewage.
In order to solve and improve the problems, researchers at home and abroad put forward and perfect an advanced oxidation technology method for treating circulating cooling water, and the method has good effect by comprehensively utilizing light, sound, electricity, magnetism or nontoxic reagent catalytic oxidation technology to treat organic sewage. Advanced oxidation technology can treat organic pollutant components which are difficult to degrade before and have great harm to biological environment, thereby becoming the front edge of current sewage treatment research and application. The electrochemical water treatment technology is used as one of advanced oxidation technologies, and is a good choice of industrial circulating cooling water treatment technology due to the advantages of cleanliness, environmental friendliness, low water consumption and the like.
The electrochemical water treatment technology is a technical process of generating a large amount of free radicals through a series of designed chemical reactions, electrochemical processes or physical processes in specific electrochemical water treatment equipment under the action of an externally applied electric field, and further degrading pollutants in wastewater by utilizing the strong oxidizing property of the free radicals, and has incomparable advantages compared with other water treatment technologies as a clean treatment process, and is an important method for solving the negative problems caused by using chemical agents in the field of industrial water treatment. The electrochemical circulating water quality stabilization treatment technology has good effects of corrosion inhibition, scale inhibition, sterilization and algae removal, the circulating water applying the technology does not need to be added with any chemical agent, and the forced sewage is small in quantity, so that not only can the agent cost and the water supplementing cost be saved, but also the technology has good effects of energy conservation, emission reduction and environmental protection.
In order to realize water treatment, the electrochemical water treatment equipment used in the prior art is provided with direct current by a direct current power supply, an anode plate is connected with a positive electrode, a cathode plate is connected with a negative electrode, electrochemical reaction is carried out, and a large amount of OH is generated on the cathode in the reaction process - In OH - Participation inThen, a reduction reaction is generated on the surface of the cathode to synthesize CaCO 3 (Ca 2+ +CO 3 2- ＝CaCO 3 ∈) and Mg (OH) 2 And other poorly soluble materials that adhere directly to the cathode to form a fouling layer; the anode plate surface is oxidized to generate a large amount of active oxidizing substances such as OH - 、Cl - O and O 3 、H 2 O 2 、Cl 2 And substances such as HClO and the like are used for sterilizing, killing algae and removing scale.
In the existing electrochemical water treatment equipment, circulating water to be treated mostly flows through a reaction area of the equipment in an S-shaped baffling waterway path, for example, an electrochemical water treatment device disclosed in China patent publication No. CN209367873U (publication No. 2019, 9, 10) is provided, wherein an S-shaped curve baffling waterway is formed by processing staggered water passing holes on a cathode plate, and the circulating water gradually fills the whole box body in the S-shaped path through the water passing holes after entering the box body of the equipment from a water inlet and flows out from a water outlet. Because the baffling waterway path prolongs the water flow treatment path, the same box volume and the same treatment time require water flow to flow through the box at a faster speed, so that the water flow is easy to wash scale forming substances accumulated near the cathode plate, thereby reducing the treatment efficiency of the equipment. In addition, the box body of the device is a closed box body, and the inside of the box body bears larger water pressure in the water treatment process, so that the treatment capacity of a single electrochemical water treatment device is limited.
In addition, scale formed on the cathode plate of the electrochemical water treatment equipment can lead to passivation of the polar plate if the scale is not removed for a long time, so that the later electrolysis efficiency and effect of the electrochemical water treatment equipment are affected. In order to facilitate the removal of scale on the cathode plate, some electrochemical water treatment devices are provided with an automatic scale removal system, a scraper is driven by a motor to scrape the scale on the surface of the cathode plate through rotary motion, and then the scraped scale is discharged out of the device through a pipeline. However, the scaling and descaling of the above equipment are required to be performed in a shutdown state, that is, the water inlet and the water outlet are required to be closed and the electrode power is required to be turned off in the descaling process, and the water treatment process of the device is stopped, so that the descaling process of the device can affect the working efficiency of the electrochemical water treatment.
In addition, the current electrochemical water treatment equipment is provided with a fixed number of cathode plates and anode plates, a group of single power supplies are used for supplying power to all the cathode plates and anode plates in the equipment, and when the water treatment equipment is used for water treatment, all the cathode plates and anode plates are subjected to electrochemical reaction after the power supply is connected, so that the water treatment capacity and the water treatment capacity of the equipment are fixed and not adjustable, and the water quality and the water volume adaptability of the electrochemical water treatment equipment to a circulating water system are poor.
