Description

Technical Field

[0001] The utility model relates to the technical field of desulfurized wastewater treatment, and particularly relates to a zero-emission treatment device for desulfurized wastewater. Background Art

[0002] Desulfurized wastewater refers to wastewater containing sulfide pollutants such as sulfur dioxide, usually generated in industrial production or energy production processes such as coal combustion and oil combustion. These pollutants can cause harm to the environment and human health, so treatment is required to reduce their impact on the environment. Zero-emission treatment means that through various technical means and processes, the pollutants generated in industrial production processes such as wastewater and waste gas are discharged to an extremely low level or even zero. This treatment method aims to protect the environment, reduce pollution to natural resources such as the atmosphere and water bodies, and achieve the coordinated development of industrial production and environmental protection. Since desulfurized wastewater contains various pollutants such as suspended solids and supersaturated sulfites, direct discharge will pollute the environment. Therefore, when discharging desulfurized wastewater, a zero-emission treatment device is usually used to treat the desulfurized wastewater. Through the zero-emission treatment device, the pollutants in the desulfurized wastewater can be effectively removed, and at the same time, the surrounding water environment can be protected, avoiding pollution to water resources such as surface water and groundwater, and thus reducing the harm to the ecosystem and human health.

[0003] When treating desulfurized wastewater through a zero-emission treatment device, in order to intercept impurity particles and suspended solids in the desulfurized wastewater, a filter plate is usually arranged inside the treatment tank to filter the impurity particles and suspended solids through the filter plate. After long-term use, the attachment of impurity particles and flocculants on the surface of the filter plate will cause accumulation. Since the impurity particles and flocculants cannot be well cleaned, the accumulation of impurity particles and flocculants is likely to cause the holes of the filter plate to be blocked, which will affect the filtering effect of the filter plate and the flow of desulfurized wastewater, thus reducing the treatment quality and efficiency of desulfurized wastewater. Therefore, in order to solve the above problems, a zero-emission treatment device for desulfurized wastewater is proposed. Content of the Utility Model

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-5 , an embodiment provided by the present invention:

[0023] The first motor 21 and the second motor 31 used in this application are products that can be directly purchased on the market, and their principles and connection methods are all well-known prior arts to those skilled in the art, so they will not be described in detail here.

[0024] A desulfurized wastewater zero-discharge treatment device includes a box body. The box body includes a processing tank 1. An adding port 11 is arranged at the top of the processing tank 1. A water inlet 12 is arranged at the top of the processing tank 1. A processing chamber 13 is arranged inside the processing tank 1. A filter plate 14 is fixedly connected inside the processing tank 1. A drainage port 15 is fixedly connected to the surface of the processing tank 1. Through the arrangement of the water inlet 12, desulfurized wastewater can be discharged into the inside of the processing chamber 13. Through the arrangement of the adding port 11, a flocculant can be put into the processing chamber 13. After the desulfurized wastewater and the flocculant react in the processing chamber 13, by opening the discharge pipe at the bottom of the processing chamber 13, the desulfurized wastewater can be filtered through the filter plate 14. The filter plate 14 can intercept impurity particles and suspended matters in the desulfurized wastewater. Through the arrangement of the drainage port 15, the treated desulfurized wastewater can be discharged;

[0025] Inside the processing box 1, a impurity removal mechanism is provided. The impurity removal mechanism includes a reciprocating lead screw 2, which is movably connected to the inside of the processing box 1. A first motor 21 is fixedly installed on the surface of the processing box 1, and the output end of the reciprocating lead screw 2 is fixedly connected to the output end of the first motor 21. A moving block 22 is movably connected to the surface of the reciprocating lead screw 2. A fixed rod 23 is fixedly connected to the lower surface of the moving block 22. An activity rod 25 is movably connected to the inside of the fixed rod 23. A brush plate 26 is fixedly connected to the bottom end of the activity rod 25. A waste discharge port 28 is opened inside the processing box 1, and a sealing plate 29 is arranged inside the waste discharge port 28. By rotating the reciprocating lead screw 2, the moving block 22 can drive the brush plate 26 to move back and forth. The movement of the brush plate 26 and the filter plate 14 rub against each other, which can clean the surface of the filter plate 14, avoid the accumulation of particulate impurities and suspended matters on the filter plate 14, and prevent the filter plate 14 from being blocked.

[0026] Furthermore, the impurity removal mechanism further includes a spring 24, which is fixedly connected to the inner wall of the fixed rod 23. A limiting rod 27 is fixedly connected to the inner wall of the processing box 1. A sealing gasket 210 is fixedly connected to the surface of the sealing plate 29. An insertion block 211 is fixedly connected to the surface of the sealing plate 29. A fixed block 212 is fixedly connected to the surface of the processing box 1. A slot 213 is opened inside the fixed block 212. A bolt 214 is threadedly connected to the inside of the fixed block 212. Through the arrangement of the limiting rod 27, the moving block 22 can be limited, thereby avoiding the deviation of the moving block 22 and ensuring the stability of the movement of the brush plate 26.

[0027] Furthermore, one end of the spring 24 is fixedly connected to the fixed rod 23, and the other end of the spring 24 is fixedly connected to the activity rod 25. The moving block 22 is movably connected to the limiting rod 27. Through the arrangement of the spring 24, a certain force can be applied to the activity rod 25, so that the brush plate 26 can better contact the surface of the filter plate 14 and ensure the cleaning effect of the brush plate 26 on the filter plate 14.

[0028] Furthermore, the insertion blocks 211 are in two groups and fixedly connected to the sealing plate 29. The fixed blocks 212 are in two groups and fixedly connected to both sides of the processing box 1. The fixed blocks 212 are fixed to the insertion blocks 211 through bolts 214. Through the arrangement of the bolts 214, the insertion blocks 211 and the fixed blocks 212 can be fixed and disassembled, which is convenient for the installation and removal of the sealing plate 29. Thus, by removing the sealing plate 29, it is convenient for impurity particles to be discharged through the waste discharge port 28.

[0029] Furthermore, a mixing mechanism is provided inside the treatment chamber 13. The mixing mechanism includes a rotating rod 3, which is movably connected to the inside of the treatment tank 1. A second motor 31 is fixedly installed at the top of the treatment tank 1. Stirring rods 32 are fixedly connected to the surface of the rotating rod 3, and scraping plates 33 are fixedly connected to the surface of the rotating rod 3. Support rods 34 are fixedly connected to the inner wall of the treatment chamber 13, and connecting blocks 35 are fixedly connected to the tops of the support rods 34. A first conical gear 36 is fixedly connected to the bottom end of the rotating rod 3. A stirring plate 37 is movably connected to the inside of the connecting block 35, and a second conical gear 38 is fixedly connected to the surface of the stirring plate 37. By driving the rotation of the stirring rods 32 and the scraping plates 33 through the rotating rod 3, the stirring rods 32 can mix the desulfurized wastewater and the flocculant, thereby improving the reaction rate. At the same time, the setting of the scraping plates 33 can prevent the suspension from adhering to the inner wall of the treatment chamber 13.

[0030] Furthermore, the rotating rod 3 is fixedly connected to the output end of the second motor 31. The rotating rod 3, the first conical gear 36, and the second conical gear 38 are all movably located inside the connecting block 35. Through the setting of the first conical gear 36 and the second conical gear 38, when the first conical gear 36 rotates under the action of the rotating rod 3, the second conical gear 38 can drive the stirring plate 37 to rotate. Thus, the stirring plate 37 can turn the desulfurized wastewater at the bottom layer of the treatment chamber 13, enabling the desulfurized wastewater at the bottom layer to react better with the flocculant.

[0031] Working principle: During use, the first motor 21 is electrically connected to an external power source. The staff starts the first motor 21 by pressing the switch. The first motor 21 operates to drive the reciprocating lead screw 2 to rotate. The moving block 22 is limited by the limiting rod 27 and will move back and forth under the action of the reciprocating lead screw 2. Thus, the fixed rod 23 and the movable rod 25 drive the brush plate 26 to move accordingly. By moving the brush plate 26, the impurity particles, flocs, etc. on the filter plate 14 can be cleaned. By turning the bolt 214, the fixation between the insertion block 211 and the fixed block 212 can be released, and then the sealing plate 29 can be pulled out from the impurity discharge port 28, enabling the impurity particles, flocs, etc. to be discharged through the impurity discharge port 28. The setting of the spring 24 can apply a certain force to the movable rod 25. Thus, when the brush plate 26 is worn to a certain extent, it can still be in contact with the surface of the filter plate 14, thereby achieving cleaning; by inserting the insertion block 211 into the inner side of the slot 213 and then fixing the insertion block 211 and the fixed block 212 through the bolt 214, at this time, the sealing gasket 210 is closely attached to the surface of the treatment tank 1, and the sealing of the impurity discharge port 28 by the sealing plate 29 can be achieved;

[0032] The second motor 31 is electrically connected to an external power supply. The operator starts the second motor 31 by pressing a switch. The operation of the second motor 31 drives the rotating rod 3 to rotate. The stirring rod 32 will rotate accordingly under the action of the rotating rod 3, enabling the stirring of the desulfurized wastewater and the flocculant in the treatment chamber 13, and thus realizing the mixing reaction. The first conical gear 36 will rotate under the action of the rotating rod 3. Then, the second conical gear 38 will rotate accordingly under the action of the first conical gear 36, driving the stirring plate 37 to rotate. Thus, the stirring plate 37 can turn over the desulfurized wastewater at the bottom layer of the treatment chamber 13, so that the bottom-layer desulfurized wastewater can better mix and react with the flocculant. The scraper 33 can also rotate under the action of the rotating rod 3 and scrape the inner wall of the treatment chamber 13 during rotation, thus preventing the flocculated suspended matter from adhering to the inner wall of the treatment chamber 13.

[0033] The above is only the preferred embodiment of the present invention and does not impose any form of limitation on the present invention.
