Description

Technical Field

[0001] The utility model relates to the technical field of waste gas purification, in particular to a waste gas purification device. Background Art

[0002] Waste gas purification is a work to treat industrial waste gas generated in industrial places. Since industrial waste gas contains a large amount of harmful substances, such as nitrogen oxides, sulfur oxides, volatile organic compounds, particulate matter, etc., these substances not only pollute the environment, but also cause serious harm to human health. The main purpose of waste gas purification is to reduce the harmful effects of waste gas on the environment and human health. Common waste gas purification methods include absorption, adsorption, condensation and combustion.

[0003] The patent with application number CN202223177508.8 discloses a VOCs waste gas purification device, which belongs to the field of waste gas purification, including a waste gas treatment equipment body, one end of the waste gas treatment equipment body is provided with a waste gas inlet end, and a pretreatment device is provided at the waste gas inlet end. Through the pretreatment device, the particle interception net in the interception box is used to achieve the effect of intercepting dust particles, and the internal environment of the interception box is heated by the electric heating wire and the VOCs waste gas passing through is dried. The removal of dust particles and water vapor in the incoming waste gas can reduce the adsorption treatment pressure of the waste gas treatment equipment, and is also conducive to the waste gas treatment equipment to quickly purify the waste gas to meet the emission standards. Through the cleaning component set, the lifting brush body is driven by the electric telescopic rod to scrape the particle interception net and the collection box with the cleaning brush block. The automatic and regular cleaning of the particle interception net can relieve its filtering pressure, and the cleaning of the inner wall of the collection box can improve the inconvenience of efficient removal after the dust sticks to the wall.

[0004] However, this patent intercepts dust particles through a particle interception net to reduce the adsorption treatment pressure of the exhaust gas treatment equipment. However, the particle interception net has a large resistance to gas flow, which slows down the gas flow speed, thereby increasing the energy consumption of the filtering equipment in disguise.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0024] like Figures 1 to 6 As shown, the utility model is an exhaust gas purification device comprising: a box body 1, a bottom plate 2 fixedly connected to the box body 1, a dust removal component 4 supporting the box body 1, an air inlet 3 opened on the box body 1, the exhaust gas enters the box body 1 through the air inlet 3, the dust removal component 4 pre-treats the dust in the exhaust gas, and a purification device 5 fixedly installed on the box body 1. The purification device 5 is an activated carbon adsorption layer installed inside the box body 1, and a filter component 6 performs secondary filtration on the exhaust gas.

[0025] The dust removal assembly 4 includes a connection box 41 fixedly connected to the air inlet 3, a cavity 42 opened on the connection box 41, a water supply pipe 43 coiled on the cavity 42, a nozzle 44 fixedly connected to the water supply pipe 43, a water pump 45 fixedly connected to the water supply pipe 43, and the water pump 45 is fixedly installed on the bottom plate 2. The dust removal assembly 4 also includes a connection sleeve 46 fixedly connected to the connection box 41, a drain port 47 opened on the connection sleeve 46, a drain pipe 48 fixedly connected to the drain port 47, a filter box 49 fixedly connected to the drain pipe 48, and a filter box 49 fixedly connected to the filter box 49. In the collecting box 410 on the filter box 49, water is pumped by a water pump 45 to flow through the water supply pipe 43 to the nozzle 44 for spraying to form water mist, so that when the exhaust gas passes through, the water mist can absorb the dust in the exhaust gas to prevent the dust from entering the box body 1. After the water mist absorbs the dust in the exhaust gas, a water flow is formed, which flows into the filter box 49 through the drain port 47 and the drain pipe 48, and can filter large particles in the exhaust gas and recover the large particles at the same time, so as to prevent the large particles from generating greater pressure on the subsequent purification structure. In addition, the water mist has less resistance to the exhaust gas and has a simple structure.

[0026] The filter box 49 is connected to the collection box 410, and both the filter box 49 and the collection box 410 are provided with water outlets. The filter box 49 is provided with a feed inlet on its upper surface. The wastewater is simply filtered through the filter box 49 and then discharged to the collection box 410. Both the filter box 49 and the collection box 410 can discharge the sewage through the water outlets. The feed inlet on the filter box 49 can be placed with a sampling device to extract the sewage inside the filter box 49, so as to facilitate the detection of the composition and content of the sewage.

[0027] The filter assembly 6 includes a support block 61 fixedly connected to the housing 1, a slide groove 62 provided on the support block 61, a slider 63 slidably connected to the slide groove 62, a threaded rod 64 threadedly connected to the slider 63, a forward and reverse motor 65 fixedly connected to the threaded rod 64, the forward and reverse motor 65 fixedly connected to the surface of the housing 1, a fixed frame 66 fixedly connected to the slider 63, a filter 67 fixedly connected to the fixed frame 66, the filter 67 filters the exhaust gas again to reduce the processing pressure of the purification device 5, a fixed plate 68 fixedly connected to the fixed frame 66, a sealing strip 69 fixedly connected to the side of the fixed plate 68, and a sealing groove 610 provided on the housing 1. The sealing groove 610 and the sealing strip 69 cooperate with each other to enable the fixed plate 68 to fit the surface of the housing 1 When the filter 67 is on the surface, the surface of the fixed plate 68 and the box body 1 are sealed. When the filter 67 needs to be replaced, the forward and reverse motor 65 is started to drive the threaded rod 64 to rotate. The threaded connection between the threaded rod 64 and the slider 63 drives the slider 63 to slide inside the slide groove 62. At the same time, the slider 63 is limited by the slide groove 62 to avoid sliding, so that the fixed frame 66 drives the filter 67 to slide out from the inside of the box body 1, which is convenient for maintenance personnel to replace. Then the forward and reverse motor 65 reverses to drive the filter 67 into the inside of the box body 1, and at the same time makes the fixed plate 68 fit against the surface of the box body 1. At this time, the sealing strip 69 enters the inside of the sealing ring, which can seal the connection between the fixed plate 68 and the box body 1, thereby improving the convenience of replacing the filter 67 of the device without manual opening.

[0028] Working principle: The water flow is pumped by the water pump 45 through the water supply pipe 43 to the nozzle 44 to spray out to form water mist, so that when the exhaust gas passes through, the water mist can absorb the dust in the exhaust gas to prevent the dust from entering the box body 1. The water mist absorbs the dust in the exhaust gas to form a water flow, which flows into the filter box 49 through the drain port 47 and the drain pipe 48. Then the exhaust gas is filtered through the filter 67 and the purification device 5 to complete the treatment of the exhaust gas. Then, when the filter 67 needs to be replaced, the forward and reverse motor 65 is started to drive the threaded rod 64 to rotate, and the filter 67 is replaced. The threaded connection between the threaded rod 64 and the slider 63 drives the slider 63 to slide inside the slide groove 62. At the same time, the slider 63 is limited by the slide groove 62 to prevent sliding, so that the fixed frame 66 drives the filter 67 to slide out from the inside of the box body 1, which is convenient for maintenance personnel to replace it. Then the forward and reverse motor 65 reverses to drive the filter 67 into the inside of the box body 1, and at the same time makes the fixed plate 68 fit the surface of the box body 1. At this time, the sealing strip 69 enters the inside of the sealing ring, which can seal the connection between the fixed plate 68 and the box body 1.
