Description

Technical Field

[0001] This invention belongs to the field of landfill leachate treatment technology, specifically relating to a special oxidation device for landfill leachate. Background Technology

[0002] Oxidation treatment of landfill leachate is an important method for treating leachate generated in landfills. Leachate is a liquid formed during the landfill process when rainwater, groundwater, and other water seep into the landfill. It contains large amounts of organic matter, ammonia nitrogen, heavy metals, and other pollutants.

[0003] Electrocatalytic oxidation is an emerging technology for treating landfill leachate, utilizing electrochemical methods to degrade organic pollutants in the leachate through electrode catalytic reactions. However, most existing landfill leachate oxidation treatment equipment uses a fixed oxidation process, requiring the leachate to remain in the oxidation tank for a certain period before discharge. This oxidation method is inefficient, with limited oxidation capacity per cycle, and results in significant sediment buildup in the leachate, necessitating regular cleaning of the oxidation tank and hindering continuous oxidation treatment of landfill leachate. Utility Model Content

[0004] The purpose of this invention is to provide a special oxidation device specifically for landfill leachate, which can perform flow oxidation of landfill leachate, thereby increasing the treatment efficiency of leachate and reducing the deposition of stains in leachate.

[0005] The specific technical solution adopted in this utility model is as follows:

[0006] A special oxidation device for landfill leachate includes a housing, the right end of which is not sealed. Two connecting pipes are fixedly connected to the side wall of the housing, and a sealing cover is fitted to the right side wall of the housing. Several electrode plates are arranged in the inner cavity of the housing. The electrode plates are spiral-shaped, and two conductive rods are fixedly connected to the side wall of the electrode plates. A support plate is slidably connected to the inner cavity of the housing. The support plate has a cavity inside and several through holes on its side wall. The other end of each conductive rod extends into the cavity, and a conductive component is arranged in the cavity. Two fixing plates are fixedly connected symmetrically to the upper and lower sides of the housing.

[0007] The conductive component includes an electrode sheet fixedly connected to the inner wall of the cavity, a conductive rod abutting against the electrode sheet, and a wire fixedly connected to the other end of the electrode sheet, the wire extending to the outside of the sealing cover.

[0008] The inner wall of the box has two limiting grooves, which penetrate through the end face of the box, and the support plate is movably connected to the limiting grooves.

[0009] The conductive rod is fitted with a sealing sleeve on its side wall, which abuts against the side wall of the support plate. Several screws are movably connected to the side wall of the sealing sleeve, and the screws are threadedly connected to the support plate.

[0010] The sealing cover has two flanges on its side wall, and bolts are movably connected to the side wall of the flanges. The bolts are threaded to the sealing cover, and the wire passes through the flange.

[0011] The flange sidewall is fitted with a sealing ring, which is located between the sealing cover and the flange.

[0012] The technical effects achieved by this utility model are as follows:

[0013] This utility model discloses a special oxidation device specifically designed for landfill leachate. Through the cooperation of the tank, sealing cover, electrode plate, and conductive components, multiple tanks can be connected in series according to actual oxidation requirements. This allows the leachate to flow through multiple tanks for oxidation before being discharged. The flow oxidation method allows the leachate to flow fully on the electrode surface, increasing the contact area between the leachate and the electrode, thereby enhancing the effect of the electrocatalytic reaction. Furthermore, under flow conditions, the flow of leachate can carry away the reaction products generated on the electrode surface, preventing these products from inhibiting the electrocatalytic reaction and increasing the reaction rate.

[0021] To make the purpose and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0022] like Figure 1-Figure 5 As shown, a special oxidation device for landfill leachate includes a housing 1. The right end of the housing 1 is not sealed. Two connecting pipes 2 are fixedly connected to the side wall of the housing 1. A sealing cover 3 is installed on the right side wall of the housing 1. Several electrode plates 4 are arranged in the inner cavity of the housing 1. The electrode plates 4 are spiral-shaped. Two conductive rods 5 are fixedly connected to the side wall of the electrode plates 4. A support plate 7 is slidably connected to the inner cavity of the housing 1. A cavity 8 is opened inside the support plate 7. Several through holes 9 are opened on the side wall of the support plate 7. The other end of the conductive rods 5 extends into the cavity 8. A conductive component is arranged in the cavity 8. Two fixing plates 17 are fixedly connected symmetrically to the upper and lower sides of the side wall of the housing 1.

[0023] like Figure 2 and Figure 3 As shown, the conductive component includes an electrode plate 10 fixedly connected to the inner wall of the cavity 8, a conductive rod 5 abutting against the electrode plate 10, and a wire 11 fixedly connected to the other end of the electrode plate 10, the wire 11 extending to the outside of the sealing cover 3.

[0024] Among them, the electrode sheet 10 can be made of elastic material. When the conductive rod 5 contacts the electrode sheet 10, the elastic properties of the electrode sheet 10 can always be tightly attached to the conductive rod 5, which is used to supply power to multiple electrode plates 4.

[0025] Two limiting grooves 6 are provided on the inner wall of the housing 1. The limiting grooves 6 penetrate through the end face of the housing 1. The support plate 7 is movably connected to the limiting grooves 6. The other end of the support plate 7 is detachably mounted on the sealing cover 3. When the electrode plate 4 needs to be removed for cleaning, the sealing cover 3 is opened, and the support plate 7 and the electrode plate 4 are removed together. Then the support plate 7 is removed from the sealing cover 3, and the electrode plates 4 can be removed one by one for maintenance.

[0026] like Figure 3 As shown, a sealing sleeve 12 is fitted onto the side wall of the conductive rod 5. The sealing sleeve 12 abuts against the side wall of the support plate 7. Several screws 13 are movably connected to the side wall of the sealing sleeve 12, and the screws 13 are threadedly connected to the support plate 7. By using the sealing sleeve 12 to seal the conductive rod 5 and the through hole 9, it is possible to prevent leachate from entering the cavity 8 and causing a short circuit, thereby achieving a highly efficient sealing effect.

[0027] like Figure 4As shown, the sealing cover 3 has two flanges 14 on its side wall. Bolts 15 are movably connected to the side wall of the flanges 14, and the bolts 15 are threadedly connected to the sealing cover 3. The wire 11 passes through the flanges 14. A sealing ring 16 is installed on the side wall of the flanges 14, and the sealing ring 16 is located between the sealing cover 3 and the flanges 14. On the one hand, it can seal the sealing cover 3 to prevent leakage of leachate; on the other hand, it can limit and seal the wire 11, facilitating the connection of the wire 11 to external power supply equipment and control equipment.

[0028] The working principle of this utility model is as follows: First, according to the oxidation treatment requirements, a specified number of tanks 1 are connected by fixing plates 17, and the tanks 1 are connected end to end by external pipes. Then, wires 11 are connected to external power supply equipment. Then, the leachate is discharged into the first tank 1, and the electrode plate 4 is energized to oxidize the leachate. The leachate flows through multiple tanks 1 through pipes. After flowing into the last tank 1, the oxidation process is completed and the leachate is discharged. The use of flow oxidation treatment can effectively improve the treatment efficiency of leachate.

[0029] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
