Description

Technical Field

[0001] This utility model specifically relates to the technical field of waste gas treatment devices, and more specifically to a high-efficiency cyclone spray waste gas treatment device. Background Technology

[0002] With the acceleration of industrialization, a large amount of waste gas is emitted from industrial production, causing serious pollution to the atmospheric environment and threatening ecological balance and human health. In order to reduce waste gas pollution and protect the ecological environment, countries have formulated strict waste gas emission standards. Enterprises must treat the waste gas generated during the production process to meet the emission standards before it can be discharged.

[0003] Traditional cyclone scrubbing towers also have some operational problems. For example, the scrubbing liquid in some cyclone scrubbing towers is typically used only once, leading to high waste gas treatment costs and resource waste. Furthermore, when treating certain complex waste gases, the scrubbing liquid reacts with the waste gas to generate solid waste or contain a large amount of particulate matter. Direct discharge or recycling of untreated scrubbing liquid will reduce the treatment effect and may also clog pipes and nozzles, affecting the normal operation of the equipment. Additionally, some cyclone scrubbing towers do not consider the effective management and utilization of the bottom circulating water, which may affect the treatment effect and equipment lifespan due to impurity accumulation and water quality changes. Utility Model Content

[0004] The purpose of this utility model is to provide a high-efficiency cyclone spray type waste gas treatment device. By installing the waste gas and wastewater filtration device and the spraying device into the outer shell of the cyclone spray tower, the tower body can realize water circulation when treating waste gas, thereby improving water resource utilization and reducing industrial costs; thus solving the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-efficiency cyclone spray exhaust gas treatment device, comprising:

A filter screen is provided on one side of the circulating water tank and is connected to the water tank.

[0009] As a further technical solution of this utility model, the bottom of the base is connected to the mounting bracket, and the top end is also connected to the tower body.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-8 In this embodiment of the utility model, a high-efficiency cyclone spray type exhaust gas treatment device includes a cyclone spray tower shell 1, an exhaust gas and wastewater filtration device 3 is provided inside the cyclone spray tower shell 1, and a spray device 2 is installed on one side.

[0030] The waste gas and wastewater filtration device 3 includes a circulating water tank 31, which is located at the upper end of the base 12. The inner side of the upper end of the circulating water tank 31 is provided with a grille 32. The bottom of the grille 32 is provided with a double-layer activated carbon filter plate 33, which is also located on the inner side of the upper end of the circulating water tank 31. A filter screen 34 is provided on one side of the circulating water tank 31, and the filter screen 34 is connected to the water tank 21.

[0031] The base 12 is connected to the mounting bracket 11 at the bottom and to the tower body 13 at the top. The side surface of the tower body 13 is regularly provided with an air inlet 14 and two observation ports 15. The top of the tower body 13 is provided with a top cover 16, and the upper end of the top cover 16 is provided with an air outlet 17.

[0032] The water tank 21 has a maintenance port 22 at the top, a level gauge 23 at one end, a water supply pipe 24 and a drain pipe 25 on one side, and the other end is connected to a water pump 26. The other end of the water pump 26 is connected to a spray pipe 27.

[0033] By adopting the above technical solution, the sprayed liquid flows to the circulating water tank 31 after spraying. The design of the circulating water tank 31, the grid 32, the double-layer activated carbon filter plate 33, and the filter screen 34 realizes the recycling of the sprayed liquid, reduces the waste of water resources, and lowers the cost of waste gas treatment. At the same time, the multi-stage filtration treatment of the sprayed liquid by the grid 32, the double-layer activated carbon filter plate 33, and the filter screen 34 ensures the quality of the sprayed liquid and avoids the impact of water quality problems on the waste gas treatment effect and the stability of equipment operation.

[0034] In this embodiment, the spray pipe 27 is regularly provided with two liquid distribution pipes 28, which are connected to the middle and upper activated carbon filter screen 39 and the upper activated carbon filter screen 310 respectively. The liquid distribution pipe 28 is provided with multiple spiral nozzles 29.

[0035] The upper and middle activated carbon filter screens 39 and 310 are connected to the inner wall of the tower body 13. The upper and middle activated carbon filter screen 39 is located at the bottom of the upper activated carbon filter screen 310, and the upper end of the upper activated carbon filter screen 310 is connected to the demisting layer 311. The bottom of the upper and middle activated carbon filter screen 39 is provided with a lower and middle activated carbon filter screen 38. The bottom of the lower and middle activated carbon filter screen 38 is connected to the upper swirl fan 37. The bottom of the upper swirl fan 37 is provided with a lower activated carbon filter screen 36. The bottom of the lower activated carbon filter screen 36 is connected to the lower swirl fan 35. The bottom of the lower swirl fan 35 is provided with a circulating water tank 31.

[0036] The lower swirl fan 35, the lower activated carbon filter 36, the upper swirl fan 37, and the middle and lower activated carbon filter 38 are all connected to the inner wall of the tower body 13, and the air inlet 14 is located between the upper swirl fan 37 and the lower activated carbon filter 36.

[0037] By adopting the above technical solution, when treating the exhaust gas, the lower swirl fan 35 and the upper swirl fan 37 create a swirling flow in the exhaust gas. The dual swirl fan configuration greatly increases the contact area and time between the exhaust gas and the spray liquid and the multi-layer activated carbon filter, thereby improving the removal efficiency of various pollutants in the exhaust gas. The multi-layer activated carbon filter further enhances the adsorption capacity for different types of pollutants, ensuring that the discharged exhaust gas can reach a high purification standard. After being treated by multiple layers, the exhaust gas finally passes through the demister layer 311, which removes the water mist carried in the exhaust gas, allowing the purified dry exhaust gas to be discharged from the air outlet 17 at the top of the top cover 16, achieving highly efficient purification.

[0038] The working principle of this utility model is as follows: the exhaust gas containing pollutants enters the device from the air inlet 14 on the side surface of the tower body 13. The exhaust gas first comes into contact with the lower swirl fan 35. The high-speed rotation of the lower swirl fan 35 causes the exhaust gas to generate swirling motion. Under the action of centrifugal force, the larger particulate pollutants in the exhaust gas are thrown towards the inner wall of the tower body 13 and fall into the circulating water tank 31 under the action of gravity. Then, the exhaust gas passes through the lower activated carbon filter 36. The adsorption effect of the activated carbon further removes some impurities and harmful gases in the exhaust gas.

[0039] The pre-treated exhaust gas continues to rise and encounters the upper swirl fan 37, generating swirl again to enhance the mixing effect between the exhaust gas and the subsequent treatment medium. At the same time, the water in the water tank 21 is pressurized by the water pump 26 and reaches the liquid distribution pipe 28 through the spray pipe 27, and is sprayed out by the spiral nozzle 29 to form a spray liquid. During the process of full contact with the swirling exhaust gas, the spray liquid absorbs water-soluble pollutants in the exhaust gas, such as acidic or alkaline gases. The mixture of exhaust gas and liquid after spraying continues to rise and passes through the middle and lower activated carbon filter screen 38, the middle and upper activated carbon filter screen 39 and the upper activated carbon filter screen 310 in sequence. The multi-layer activated carbon filter screen further adsorbs the residual pollutants in the exhaust gas and the small particles in the spray liquid, purifying the exhaust gas while playing a certain filtering role in the spray liquid. After being treated by multiple layers, the exhaust gas finally passes through the demister layer 311. The demister layer removes the water mist carried in the exhaust gas, so that the purified dry exhaust gas is discharged from the air outlet 17 at the top of the top cover 16.

[0040] When treating exhaust gas, the exhaust gas is swirled by the lower swirl fan 35 and the upper swirl fan 37. The dual swirl fan configuration greatly increases the contact area and time between the exhaust gas and the spray liquid and the multi-layer activated carbon filter, thereby improving the removal efficiency of various pollutants in the exhaust gas. The multi-layer activated carbon filter further enhances the adsorption capacity for different types of pollutants, ensuring that the discharged exhaust gas can meet a high purification standard. After being treated by multiple layers, the exhaust gas finally passes through the demister layer 311. The demister layer removes the water mist carried in the exhaust gas, allowing the purified dry exhaust gas to be discharged from the air outlet 17 at the top of the top cover 16, achieving high-efficiency purification.

[0041] The circulating water tank 31 collects pollutants and spray liquid falling from the inner wall of the tower body 13. The grid 32 on the inner side of the upper end of the circulating water tank 31 first intercepts larger solid impurities. The double-layer activated carbon filter plate 33 further adsorbs impurities and harmful substances in the water. The filter screen 34 on one side of the circulating water tank 31 transports the pre-filtered water to the water tank 21 to realize the recycling of water. The level gauge 23 on the water tank 21 can monitor the water level in real time. The water supply pipe 24 is used to replenish the water lost due to evaporation. The drain pipe 25 can periodically discharge the impurities and sewage accumulated at the bottom of the water tank.

[0042] After being sprayed, the spray liquid flows into the circulating water tank 31. The design of the circulating water tank 31, the grille 32, the double-layer activated carbon filter plate 33, and the filter screen 34 realizes the recycling of the spray liquid, reduces water waste, and lowers the cost of waste gas treatment. At the same time, the multi-stage filtration treatment of the spray liquid by the grille 32, the double-layer activated carbon filter plate 33, and the filter screen 34 ensures the quality of the spray liquid and avoids the impact of water quality problems on the waste gas treatment effect and the stability of equipment operation.
