Description

Technical Field

[0001] This utility model relates to the field of industrial ultrapure water treatment technology, and in particular to a wastewater recycling and reuse device for industrial ultrapure water. Background Technology

[0002] Industrial ultrapure water contains virtually no impurities, including microorganisms, particulate matter, and organic matter. It has wide applications in various fields, including electronics, pharmaceuticals, and chemicals. However, the rinsing water in the later stages of ultrapure water treatment contains a certain amount of oxidants such as hydrogen peroxide or ozone. If this rinsing water is directly discharged into the wastewater system, it may affect the normal operation of the biochemical system in the wastewater treatment system or increase the load on the wastewater treatment system.

[0003] A wastewater recycling and reuse device for industrial ultrapure water, application number CN202020904099.9, is described. The device includes a reducing agent inlet on the side surface of a tank, an inlet pipe A connected to the side surface of the tank, and a reduction tank connected to the lower end of the inlet pipe B. Ultraviolet lamps are evenly distributed on the inner surface of the reduction tank. The reduction tank is connected to the tank via a connecting pipe with a control valve in the middle. An outlet pipe is located at the lower end of the side surface of the tank, and an oxidation-reduction potentiometer is installed on the inner surface of the tank. For ultrapure water containing both ozone and hydrogen peroxide, the ozone in the ultrapure water is catalytically reduced using ultraviolet light of a specific wavelength. Then, a reducing agent is added to reduce the hydrogen peroxide. The remaining oxidant in the treated water is then catalytically decomposed by an activated carbon filter, resulting in the lowest possible oxidation-reduction potential in the effluent. The remaining oxidant in the ultrapure water is then catalytically decomposed again by the activated carbon filter before being discharged. However, after use, dirt remains on the side wall of the tank, making it difficult for users to clean the tank and affecting the subsequent treatment effect. Utility Model Content

The ultraviolet lamp uses a specific wavelength of ultraviolet light to catalytically reduce the ozone in the ultrapure water. The ultrapure water containing hydrogen peroxide is then discharged into treatment tank 1. The activated carbon filter box 3 is existing technology. Its principle is mainly based on the physical and chemical adsorption of activated carbon, which can effectively adsorb impurities in liquids. The oxidation-reduction potentiometer 4 is existing technology. It is an instrument used to measure the oxidation-reduction potential in a solution. It is a physical quantity that measures the balance between oxidants and reductants in a solution and reflects the ability of electron transfer in the solution. It can detect the reaction status of the solution. The processing tank 1 is equipped with a heating component, a stirring component and a cleaning component. The processing tank 1 has a working port.

[0022] The cleaning assembly includes a mounting bracket 5 fixedly connected to the upper end face of the treatment tank 1. A first motor 6 is fixedly mounted on the upper end face of the mounting bracket 5. A rotating ring 7 is rotatably connected to the inner wall of the working port. A fixed bracket 8 is rotatably connected to the rotating ring 7. The fixed bracket 8 is fixedly connected to the upper end face of the treatment tank 1. A connecting pipe 9 rotatably passes through the fixed bracket 8. A multi-head nozzle 10 is fixedly connected to the connecting pipe 9. A water supply pipe 11 is rotatably connected to the connecting pipe 9. A first rotating gear 12 is fixedly connected to the side wall of the connecting pipe 9. A second rotating gear 13 and a third rotating gear are rotatably connected to the upper end face of the fixed bracket 8. The first rotating gear 12 and... The second rotating gear 13 meshes with each other, the first rotating gear 12 and the third rotating gear mesh with each other, the rotating end of the first motor 6 is fixedly connected to the second rotating gear 13, the upper end face of the rotating ring 7 is fixedly connected to the toothed ring 14, the toothed ring 14 and the third rotating gear mesh with each other, the lower end face of the rotating ring 7 is fixedly connected to the connecting frame, two scrapers 15 are fixedly connected to the connecting frame, the upper end face of the treatment tank 1 is fixedly connected to the limit frame 16, the water pipe 11 passes through the limit frame 16, one end of the water pipe 11 is provided with a water supply device, which can deliver pressurized water into the water pipe 11, so that the water flow is sprayed out from the multi-head nozzle 10;

[0023] The heating assembly includes a heating chamber 17 on the processing tank 1, with multiple heating rods fixedly installed on the inner wall of the heating chamber 17. A temperature sensor 18 is installed on the processing tank 1. The temperature sensor 18 is existing technology and can detect the temperature of the solution in the processing tank 1, which will not be described in detail here. The stirring assembly includes a second motor fixedly installed on the lower end face of the processing tank 1. A rotating rod is rotatably connected to the inner wall of the processing tank 1. The rotating end of the second motor is fixedly connected to the rotating rod. Multiple stirring rods 19 are fixedly connected to the side wall of the rotating rod. The stirring assembly can stir the solution and accelerate the reaction rate of the solution. The processing tank 1 is connected to an injection pipe 20 and a drain pipe.

[0024] The treatment tank 1 is connected to an infusion pipe, on which a solenoid valve is installed. The activated carbon filter box 3 is installed at the end of the infusion pipe away from the treatment tank 1. The solenoid valve is existing technology, which controls the opening and closing of the valve by generating a magnetic field through an electromagnet. The main components are the electromagnet and the valve body. When energized, the electromagnet generates a strong magnetic field, attracting the armature, which causes the valve core to overcome the spring force, gravity, and other forces, opening the valve core, and the valve is in the open state. When de-energized, the electromagnet loses its magnetism, the magnetic field disappears, and the valve core is closed by the spring force, gravity, and other factors, and the valve is in the closed state. This will not be elaborated further here.

[0025] The detailed working process of this utility model is as follows:

[0026] If the ambient temperature is too low during the processing operation, the temperature inside the processing tank 1 can be controlled by using a heating rod in conjunction with a temperature sensor 18, thereby ensuring the processing efficiency of the device. When it is necessary to clean the inside of the processing tank 1, the first motor 6 starts working, the second rotating gear 13 starts rotating, and the first rotating gear 12 starts rotating, causing the connecting pipe 9 to rotate on the fixed frame 8. At the same time, water is injected into the water supply pipe 11, causing water to spray out from the multi-head nozzle 10 to automatically rinse the inner wall of the processing tank 1, reducing the workload of the staff. Meanwhile, the first rotating gear 12 drives the third rotating gear to rotate, and the third rotating gear drives the gear ring 14 to rotate, causing the rotating ring 7 to rotate. This allows the scraper 15 to scrape off the stains attached to the inner wall of the processing tank 1, improving the cleaning effect. Moreover, the scraping direction is opposite to the rotation direction of the multi-head nozzle 10, resulting in a better cleaning effect.
