Description

Technical Field

[0001] This invention relates to the field of electrochemical water treatment technology, and in particular to an electrochemical water treatment device. Background Technology

[0002] Electrochemical water treatment refers to the process of degrading pollutants in wastewater through specific chemical reactions, electrochemical processes, or physical processes under the influence of electrodes or an applied electric field. This method is carried out in a specific electrochemical reactor, utilizing the chemical substances generated by electrode reactions and physical processes to achieve pollutant removal and water purification.

[0003] Electrochemical water treatment technology exhibits excellent corrosion inhibition, scale inhibition, and bactericidal and algae-killing effects. Circulating water treated with this technology requires no chemical additives and generates minimal forced wastewater discharge, saving on chemical and makeup water costs while also providing significant energy savings, emission reduction, and environmental protection benefits. As a clean treatment process, electrochemical technology offers unparalleled advantages compared to other water treatment technologies and is a crucial method for addressing the negative consequences of using chemical agents in industrial water treatment.

[0004] In electrochemical water treatment, ions in the water undergo a series of chemical reactions under the influence of an electric field. This is especially true for circulating water containing large amounts of calcium. 2+ Mg 2+ Metal ions and CO3 2- HCO3 - Anions, such as CaCO3 and MgCO3, can easily combine under appropriate conditions to form precipitates, thus forming scale.

[0005] Scale can cover the electrode surface, hindering the electrolysis reaction and causing a decrease in efficiency. The scale layer on the electrode surface reduces the current transmission efficiency, thus affecting the electrolysis reaction. Scale increases the resistance of the electrode, leading to increased power consumption. To maintain the same treatment effect, it may be necessary to increase the current intensity, further increasing energy consumption. Scale can also corrode the electrode material, causing the electrode surface to become rough and even corroded. This not only affects the service life of the electrode but may also cause equipment failure. Summary of the Invention

[0030] Example 1

[0031] like Figures 1-6 As shown:

[0032] An electrochemical water treatment device includes a purified water tank 1, which has an inlet 102 and an outlet 103 that penetrate the side wall of the purified water tank 1, and support legs 2 are installed at the bottom of the purified water tank 1 near the four corner edges.

[0033] In this embodiment, the water inlet 102 is located on the left side wall of the purified water tank 1, and there are two water inlets 102 arranged horizontally side by side; the water outlet 103 is located on the right side wall of the purified water tank 1, and there are two water outlets 103 arranged horizontally side by side.

[0034] An inlet pipe 3 and an outlet pipe 4 are installed at the inlet 102 and outlet 103 on the side wall of the purified water tank 1, respectively. A filter screen 14 is installed at the inner end of the outlet pipe 4.

[0035] The inlet pipe 3 and the outlet pipe 4 are connected to the inlet 102 and the outlet 103 respectively via a T-shaped water pipe.

[0036] Symmetrically arranged shelf plates 101 are installed at the bottom of the left and right side walls of the purified water tank 1. A support frame 5 spanning the purified water tank 1 is provided on the purified water tank 1, and the bottom of the support frame is set on the shelf plate 101.

[0037] The support frame 5 includes two external brackets. A crossbeam 6 spanning the purified water tank 1 is provided on the top of the external brackets. A tripod 7 is provided at the bottom of the crossbeam 6 near both ends. The tripods 7 are connected by a crossbar 601. The bottom of the external brackets is installed on the shelf 101.

[0038] An electrode rod 8 is installed on the crossbar 601 and is located inside the purified water tank 1. The top of the electrode rod 8 is connected to the crossbar 601, and a support pad 801 is provided between the bottom of the electrode rod 8 and the inner bottom surface of the purified water tank 1.

[0039] The electrode rods 8 are vertically arranged in a rectangular array.

[0040] A descaling cylinder 9, which slides along the electrode rod 8, is fitted onto the electrode rod 8. The descaling cylinder 9 is cylindrical, and scrapers are provided at both ends of the descaling cylinder 9. The blades of the scrapers are in close contact with the outer wall of the electrode rod 8. By reducing the contact area between the descaling cylinder 9 and the scale on the electrode rod 8, the pressure is increased, thereby enabling better removal of scale.

[0041] The descaling cylinders 9 are connected by a connecting rod 901.

[0042] The support frame 5 is connected to the reciprocating drive device located inside the purified water tank 1 via the support rod 10. In this embodiment, the reciprocating drive device is an electric telescopic rod 11. The moving end of the electric telescopic rod 11 is connected to the connecting rod 901, and the fixed end of the electric telescopic rod 11 is connected to the support rod 10.

[0043] The electric telescopic rod 11 is set vertically and parallel to the electrode rod 8.

[0044] The bottom of the purified water tank 1 is provided with a scale storage tank 12, and the bottom of the scale storage tank 12 is provided with a discharge port 1201. A discharge cover 13 can be detachably installed at the discharge port 1201.

[0045] The specific usage and function of this embodiment are as follows:

[0046] In this invention, the operator operates the inlet pipe 3 to deliver electrochemical water into the purified water tank 1. The electrode rod 8 is energized to precipitate scale in the electrochemical water. The descaling cylinder 9 slides up and down under the action of the electric telescopic rod 11 to clean the scale generated on the electrode rod 8. After the scale is scraped off by the descaling cylinder 9, it flows with the water flow to the outlet 103. The water flows out through the outlet pipe 4. The filter screen 14 intercepts the scale, and the intercepted scale accumulates in the scale storage tank 12. After the equipment stops running, the discharge cover 13 is opened to clean the scale.

[0047] This invention improves the stability of the electrode rod by using a support pad that slides up and down the descaling cylinder to remove scale from the electrode rod, thus preventing damage to the equipment caused by pulling down the electrode rod when removing stubborn scale. Furthermore, the descaling cylinder with a scraper and a reciprocating drive device scrape away scale from the electrode rod, preventing scale buildup and improving the electrolysis efficiency of the electrode rod. This avoids increased power consumption and reduced motor lifespan due to increased resistance from scale buildup, thereby enhancing descaling efficiency and improving the electrochemical water treatment effect.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
