Description

Technical Field

[0001] This utility model relates to the field of environmental protection technology, specifically a waste gas treatment device that allows for the recycling of waste gas. Background Technology

[0002] In modern industrial production activities, industries such as chemical, power, and metallurgy continuously generate industrial waste gases containing pollutants such as sulfides and particulate matter. If these untreated waste gases are directly released into the atmosphere, they will not only damage the ecological environment and cause environmental problems such as acid rain and smog, but also cause serious harm to the human respiratory and cardiovascular systems, threatening public health.

[0003] Currently, most of the existing waste gas treatment equipment on the market adopts single spray purification or simple adsorption treatment methods, which have technical drawbacks: traditional spray devices are mostly fixed structures with limited spray range, making it difficult for the purification liquid to fully contact the waste gas, resulting in low removal efficiency of harmful components (such as sulfides) in the waste gas, and failing to meet increasingly stringent environmental emission standards.

[0004] Based on this, a waste gas treatment device that allows for the recycling of waste gas is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0005] The purpose of this invention is to provide a waste gas treatment device that allows for the recycling of waste gas, in order to solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A waste gas treatment device for recyclable waste gas includes a purification tank and a liquid injection tank. The top wall of the purification tank is provided with an exhaust port. A drive box is fixedly connected through the purification tank. A spray assembly is installed in the drive box. A water inlet pipe is installed on the side wall of the purification tank. The liquid injection tank is fixedly connected to the purification tank by a bracket. A water inlet is provided on the side wall of the liquid injection tank. A valve is provided at the water inlet. One end of the water inlet pipe is connected to the liquid injection tank and the other end is connected to the spray assembly. An air inlet hole is provided on the side wall of the purification tank. A drain outlet is provided on the bottom wall of the purification tank.

[0007] Based on the above technical solutions, this utility model also provides the following optional technical solutions: In one alternative embodiment: the spray assembly includes a rotating pipe and spray pipes. The drive box is connected to the rotating pipe via bearings. Three circumferentially distributed spray pipes are arranged around the rotating pipe. Each spray pipe has several spray holes. The portion of the rotating pipe located inside the drive box is fixedly connected to a first synchronous pulley. The drive box is connected to a first rotating shaft via bearings. A motor is mounted on the side wall of the drive box. The output end of the motor is connected to the first rotating shaft. The first rotating shaft is fixedly connected to a second synchronous pulley. The second synchronous pulley and the first synchronous pulley are coupled together by a synchronous belt.

[0008] In one alternative: each of the three spray pipes has a mounting rod fixedly connected to its spray hole, and the mounting rod is connected to a rotating shaft II via a bearing. Several fan blades II are arranged around the rotating shaft II.

[0009] In one alternative: the rotating tube is provided with a plurality of fan blades on its periphery.

[0010] In one alternative: a water outlet pipe is provided between the injection tank and the drain outlet on the bottom wall of the purification vessel, and a circulation pump is installed on the water outlet pipe.

[0011] In one alternative embodiment, a filter plate is provided at the bottom of the purification vessel.

[0012] In one alternative: a purification chamber is provided at the exhaust port at the top of the purification vessel, and the top and bottom walls of the purification chamber are provided with openings, and an activated carbon plate is installed inside the purification chamber.

[0013] In one alternative: a second filter plate is installed inside the purification chamber.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes a motor-driven synchronous belt pulley transmission structure to rotate the rotating pipe and spray pipe, thereby achieving rotating spraying of the purified liquid. This significantly expands the spraying range, allowing the purified liquid to fully contact the waste gas and substantially improving the absorption efficiency of harmful gases such as sulfides.

[0015] The second fan blade installed inside the spray hole of this utility model rotates under the impact of water flow, which can spread the purification liquid in all directions, further increasing the contact area between the purification liquid and the exhaust gas and enhancing the purification effect; at the same time, the first fan blade on the side of the rotating pipe rotates synchronously with the spray pipe, which can gather the exhaust gas on the side of the fan blade, promote the directional reaction between the purification liquid and the exhaust gas, and reduce the escape of harmful gases.

[0016] The purification tank at the top of this utility model is equipped with a second filter plate (HEPA filter) and an activated carbon plate in sequence. It can first filter out the fine particulate pollutants remaining in the exhaust gas, and then dehumidify through activated carbon adsorption, realizing a multi-stage treatment of "spray purification + particulate filtration + adsorption dehumidification" to ensure that the emitted gas meets the standards.

[0017] This invention constructs a purification liquid circulation system through an outlet pipe and a circulation pump. The filter plate at the bottom of the purification vessel can filter out impurities carried in the purification liquid, allowing the purification liquid to flow back to the injection tank for reuse, reducing the consumption of purification liquid and lowering the processing cost.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] In one embodiment, such as Figures 1-5 As shown, a waste gas treatment device for recyclable waste gas includes a purification vessel 1 and a liquid injection tank 6. The top wall of the purification vessel 1 is provided with an exhaust port. A drive box 4 is fixedly connected through the purification vessel 1. A spray assembly is installed in the drive box 4. A water inlet pipe 5 is installed on the side wall of the purification vessel 1. The liquid injection tank 6 is fixedly connected to the purification vessel 1 through a bracket.

An air inlet hole is provided on the side wall of the purification vessel 1, and a drain outlet is provided on the bottom wall of the purification vessel 1.

[0026] Pour the purification liquid (such as desulfurizing agent) into the injection tank 6, start the circulation pump 7, the circulation pump 7 drives the purification liquid through the water inlet pipe 5 into the rotating pipe 9, and then spray it out from the spray hole of the spray pipe 10. At the same time, the industrial waste gas is discharged into the purification tank 1 through the air inlet of the purification tank 1. The discharged air is purified by the purification liquid, such as desulfurization, to remove sulfur-containing gases from the waste gas and prevent the waste gas from being directly discharged and polluting the atmosphere.

[0027] In one embodiment, the spray assembly includes a rotating pipe 9 and spray pipes 10. The drive box 4 is connected to the rotating pipe 9 via bearings. Three circumferentially distributed spray pipes 10 are arranged around the rotating pipe 9. Each spray pipe 10 has a plurality of spray holes. The portion of the rotating pipe 9 located inside the drive box 4 is fixedly connected to a first synchronous pulley 12. The drive box 4 is connected to a first rotating shaft 15 via bearings. A motor 3 is installed on the side wall of the drive box 4. The output end of the motor 3 is connected to the first rotating shaft 15. The first rotating shaft 15 is fixedly connected to a second synchronous pulley 13. The second synchronous pulley 13 and the first synchronous pulley 12 are connected by a synchronous belt 14.

[0028] Start motor 3, which drives rotating shaft 15 to rotate. Rotating shaft 15 drives rotating tube 9 to rotate through the cooperation of synchronous pulley 13, synchronous belt 14, and synchronous pulley 12. Rotating tube 9 drives spray pipe 10 to rotate, spraying the purified liquid in a rotating manner, expanding the spray range, and ensuring full contact with the exhaust gas to improve the purification effect of the exhaust gas.

[0029] In one embodiment, each of the three spray pipes 10 has a mounting rod 18 fixedly connected to its spray hole. The mounting rod 18 is connected to a rotating shaft 16 via a bearing. Several fan blades 17 are arranged around the rotating shaft 16.

[0030] When the purified liquid passes through the spray hole of the spray pipe 10, it will cooperate with the fan blade 2 17 inside. The water flow will drive the fan blade 2 17 to rotate. While the fan blade 2 17 is rotating, it can also make the purified liquid flow spread in all directions, further expanding the spray range and making full contact with the exhaust gas.

[0031] In one embodiment, a plurality of fan blades 11 are provided on the circumference of the rotating tube 9.

[0032] During the rotation of the second rotating shaft 16, the spray pipe 10 will rotate, which will also drive the fan blade 11 to rotate. The rotation of the fan blade 11 will concentrate the exhaust gas around the fan blade 11, which is more conducive to the reaction between the purification liquid and the concentrated exhaust gas, and to the absorption of harmful gases in the exhaust gas.

[0033] In one embodiment, a water outlet pipe 8 is provided between the injection tank 6 and the drain outlet on the bottom wall of the purification vessel 1, and a circulation pump 7 is installed on the water outlet pipe 8.

[0034] Through the action of the circulating pump 7, the purified liquid is recycled in the purification vessel 1, and fully reacts with the waste gas discharged into the purification vessel 1.

[0035] In one embodiment, a filter plate 19 is provided at the bottom of the purification vessel 1.

[0036] The purified liquid can be filtered through filter plate 19.

[0037] In one embodiment, a purification box 2 is provided at the exhaust port at the top of the purification vessel 1. The top and bottom walls of the purification box 2 are provided with openings, and an activated carbon plate 20 is installed inside the purification box 2.

[0038] Adsorption and dehumidification of activated carbon plate 20.

[0039] In one embodiment, a second filter plate 21 is installed inside the purification box 2.

[0040] Filter plate 21 is a HEPA filter to prevent any residual particulate pollutants from being released into the air.

[0041] The above embodiments disclose a waste gas treatment device that allows for the recycling of waste gas. Its specific working principle and process are as follows: S1: Pour the purification liquid (such as desulfurizing agent) into the injection tank 6, start the circulation pump 7, the circulation pump 7 drives the purification liquid through the water inlet pipe 5 into the rotating pipe 9, and then sprays it out from the spray hole of the spray pipe 10. At the same time, the industrial waste gas is discharged into the purification tank 1 through the air inlet of the purification tank 1. The air discharged is purified by the purification liquid, such as desulfurization, to remove sulfur-containing gases in the waste gas and prevent the waste gas from being directly discharged and polluting the atmosphere. S2: Start motor 3. Motor 3 drives rotating shaft 15 to rotate. Rotating shaft 15 drives rotating tube 9 to rotate through the cooperation of synchronous pulley 13, synchronous belt 14, and synchronous pulley 12. Rotating tube 9 drives spray tube 10 to rotate, so as to spray the purification liquid in a rotating manner, expand the spray range, fully contact the exhaust gas, and improve the purification effect of the exhaust gas. S3: When the purified liquid passes through the spray hole of the spray pipe 10, it will cooperate with the fan blade 2 17 inside. The water flow will drive the fan blade 2 17 to rotate. While the fan blade 2 17 is rotating, it can also make the purified liquid flow spread to the surroundings, further expanding the spray range and fully contacting the exhaust gas. S4: Some pollutant particles in the exhaust gas will also fall downwards upon contact with the purification liquid, landing above filter plate 19. S5: The purified air moves upward and enters the purification chamber 2. It first passes through filter plate 21, which is a HEPA filter to prevent any residual particulate pollutants from being released into the air. The air passing through filter plate 21 then passes through activated carbon plate 20 for adsorption and dehumidification before finally being released into the air. The purified liquid can be filtered through filter plate 19 and returned to the injection tank 6. Then, through the action of circulation pump 7, the purified liquid is recycled in the purification vessel 1, fully reacting with the waste gas discharged into the purification vessel 1. After a period of time, the purified liquid can be discharged by removing one end of the outlet pipe 8 from the bottom of the purification vessel 1.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
