Description

Technical Field

[0001] The utility model belongs to the technical field of water treatment equipment, and in particular relates to a positive and negative electrode adsorption composite water treatment device. Background Art

[0002] Circulating cooling water is widely used as a cooling medium in industrial production facilities. However, during its circulation, cooling water can cause corrosion, scaling, and dirt deposits on heat exchanger equipment. Scaling reduces the equipment's heat transfer efficiency and increases energy consumption. Oxidation and corrosion can seriously shorten the service life of pipes and equipment, producing yellow rusty water and causing under-rust corrosion. Microbial growth can also form deposits within pipes, reducing the water's cross-sectional area, increasing flow resistance, and reducing heat transfer efficiency.

[0003] In the existing technology, to avoid the accumulation of dirt, large particles of impurities contained in the cooling medium are removed through two methods: chemical dosing and electronic descaling. Chemical dosing removes scale by adding scale inhibitors, slow-release agents, bactericides, etc. into the pipeline. However, these chemicals are corrosive and have side effects on pipelines and equipment. In addition, the cost of adding them is high and they affect the environment, which is completely inconsistent with energy conservation and environmental protection requirements. Electronic descaling treatment uses an anti-scaling water treatment device and electronic high-frequency and overclocking technology. It has a certain effect, but it is a physical method and has no filtering function. In actual operation, the effect is not ideal. At the same time, because high-frequency and overclocking technologies are immature and there is no online water quality detection and remote control, it is impossible to understand the changes in water quality at any time.

[0026] In the description of the present invention, it should be understood that the terms "one end", "the other end", "outside", "upper", "inside", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0027] The present invention will be further described below with reference to the accompanying drawings.

[0028] like Figure 1 As shown, a combined anode-cathode adsorption water treatment device comprises a water treatment tank 1, a filter 2, a cleaning assembly 3, and cathode-cathode plates 4. The water treatment tank 1 is constructed of stainless steel. A water inlet 5 and a water outlet 6 are provided on the side walls of the tank 1, respectively, for inputting treated wastewater and outputting treated clean water. Multiple anode-cathode plates 4 are evenly arranged within the tank 1 and can adsorb charged particles in the treated wastewater, significantly reducing the concentration of dissolved salts, colloidal particles, and other charged species in the channel water. This desalination, hardness reduction (calcium and magnesium ions), and purification of the water are achieved, achieving descaling, anti-scaling, sterilization, and algae removal.

[0029] like Figure 2As shown, a partition plate 7 is provided in the water treatment tank body 1, which divides the space in the water treatment tank body 1 into an upper cavity and a lower cavity. Among them, the water inlet 5 on the water treatment tank body 1 is connected to the upper cavity, and the water outlet 6 is connected to the lower cavity. A water passage connecting the upper cavity and the lower cavity is provided on the partition plate 7. The filter screen 2 is provided at the outlet of the water passage, and can filter large particles of impurities in the treated sewage during the process of transporting the treated sewage from the upper cavity to the lower cavity. The cleaning component 3 is provided on the top of the water treatment tank body 1, which can brush off impurities adsorbed on the filter screen 2, thereby extending the service life of the filter screen 2.

[0030] In this embodiment, the filter screen 2 is a 300-500 mesh stainless steel filter screen. The cathode and anode plates 4 are made of titanium and platinum. The cathode and anode plates 4 include a cathode plate 4-1 and an anode plate 4-2. The distance between the cathode and anode plates 4 is 10 cm.

[0031] When power is applied, the ions in the treated sewage water will migrate to the cathode plate 4-1 or anode plate 4-2 with opposite charges, be adsorbed on the corresponding cathode plate 4-1 or anode plate 4-2, and form a double electric layer on the surface of the corresponding electrode plate. The ions or charged particles are enriched and concentrated on the electrode surface.

[0032] The water treatment tank 1 comprises a cover and a treatment tank body. The treatment tank body is a tank structure with an open top. The cover is detachably fixed to the top of the treatment tank body by bolts.

[0033] Cleaning assembly 3 includes a drive motor 3-1 and a cleaning brush 3-2. The top end of cleaning brush 3-2 is rotatably connected to the cover and can rotate under the drive of drive motor 3-1. The cleaning end of cleaning brush 3-2 extends into filter 2, and during rotation, it removes large particles of impurities filtered by filter 2, causing them to settle at the bottom of filter 2.

[0034] Furthermore, a sewage outlet 8 is provided at the bottom of the treatment tank body. The bottom of the filter screen 2 is connected to the sewage outlet 8 through a sewage pipe. An electric valve is provided on the sewage outlet 8 to control the conduction or cutoff of the sewage outlet 8.

[0035] In this embodiment, a differential pressure detector is installed on the main body of the treatment tank to detect the pressure difference between the upper and lower chambers. This is to prevent a pressure difference from forming inside and outside the filter 2 when the mesh of the filter 2 becomes clogged. The differential pressure detector detects the pressure difference between the inside and outside of the filter 2 and outputs a signal. The differential pressure alarm receives the signal and activates the drive motor 3-1, which in turn drives the cleaning brush 3-2 to clean the filter 2, allowing the filter 2 to function normally.

[0036] Furthermore, the cover is provided with an exhaust port 9. An exhaust valve is provided at the end of the exhaust port 9 to enable or disable the exhaust port 9. When the pressure detector detects that the pressure in the upper chamber is too high, the exhaust port 9 can be opened to avoid damage to the treatment tank body.

[0037] When the treated sewage is purified and the cleaning process is completed, clean water is introduced into the water inlet 5, and the electric valve controls the discharge port 8 to be open. The large particles of impurities removed by the cleaning brush 3-2 are discharged through the discharge pipe and the discharge port 8, effectively preventing excessive large particles of impurities from adhering to the filter 2 and affecting the water purification efficiency.

[0038] Furthermore, water inlet flange and water outlet flange are respectively provided at the edges of the water inlet 5 and the water outlet 6. The water inlet 5 and the water outlet 6 can be connected to the water outlet pipe and water inlet pipe in different circulating water systems through the water inlet flange and the water outlet flange.

[0039] Furthermore, an online water quality detector is provided on the water outlet 6 for detecting the water quality of the treated sewage output through the water outlet 5, and transmitting the water quality status data obtained from the detection to the computer room control terminal, so that the operating personnel can remotely monitor and control the water quality of the output treated sewage.

[0040] In this embodiment, the water quality online detector adopts an online conductivity detector to detect the cleanliness of water quality.

[0041] The working principle of this utility model is as follows:

[0042] During the cleaning process, the treated sewage is introduced from the water inlet 5. At the same time, the cathode and anode electrodes 4 are energized, which absorb the dissolved salts, colloidal particles and other charged substances in the treated sewage while electrolyzing the treated sewage to produce ozone and residual chlorine that can kill bacteria, thereby completing the further purification of the treated sewage.

[0043] When the treated sewage is transported from the upper cavity to the lower cavity, it will first pass through the filter 2 at the outlet of the water channel. Large particles of impurities are filtered through the filter 2, completing further purification of the treated sewage.

[0044] When the treated sewage is purified and the cleaning process is complete, clean water is introduced into the water inlet 5. The drive motor 3-1 is activated through pressure differential control. The cleaning brush 3-2 rotates under the control of the drive motor 3-1, brushing off large particles of impurities attached to the filter 2. The electric valve controls the flow of sewage outlet 8. The large particles of impurities removed by the cleaning brush 3-2 are discharged through the sewage pipe and sewage outlet 8. At the same time, by short-circuiting the cathode plate 4-1 and the anode plate 4-2, the ions adsorbed by the cathode plate 4-1 and the anode plate 4-2 are released, and the cathode plate 4-1 and the anode plate 4-2 are regenerated.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
