[0002] Waste gas treatment refers to the process of collecting, purifying and treating waste gas generated in industrial production, energy utilization and other activities. At present, in order to improve the treatment effect of waste gas, plasma treatment is used.

[0003] After searching, the patent number CN219333731U discloses a low-temperature plasma waste gas treatment device, which uses the flow of exhaust gas to blow the impeller, thereby driving the incomplete gear, and driving the mounting frame to slide through the engagement with the rack surface. When the incomplete gear rotates until the notch is opposite to the rack surface, the mounting frame is reset under the action of the spring, thereby realizing the back and forth wiping of the dust removal plate by the scraper plate, avoiding dust accumulation and reducing the dust removal effect, and further deteriorating the waste gas treatment effect of the plasma reaction device.

[0004] However, the dust removal plate is fixedly arranged inside the device. As the processing time increases, even if the dust on the dust removal plate can be cleaned, the dust will continue to increase and block the filter space, thereby reducing the exhaust gas treatment effect.

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] The utility model embodiment discloses a low-temperature plasma waste gas treatment device.

[0025] The utility model provides Figure 1-3 A low-temperature plasma waste gas treatment device shown includes a treatment device 1 and an air inlet pipe 2 and an air outlet pipe 3 connected at both ends of the treatment device 1. Both ends of the treatment device 1 are provided with air vents that cooperate with the air inlet pipe 2 and the air outlet pipe 3. A low-temperature plasma device 4 is fixedly arranged inside the treatment device 1. Two strip holes are provided on the top of the treatment device 1. Dust filter screens 5 are slidably penetrated in the two strip holes. Baffles 6 are fixedly arranged at both ends of the dust filter screens 5. A sealing ring 17 is fixedly sleeved on one side of two adjacent baffles 6. The sealing ring 17 contacts and cooperates with the treatment device 1. A vertical plate 7 is fixedly arranged on the top of the treatment device 1. A switching application mechanism for switching the two dust filter screens 5 is provided between the vertical plate 7 and the two dust filter screens 5. The switching application mechanism includes an adjusting plate 8. A support rod 9 is fixedly penetrated at the upper end of the interior of the vertical plate 7. The adjusting plate 8 is rotatably sleeved on the outer side of the support rod 9. Two symmetrically arranged sliding holes 10 are provided inside the adjusting plate 8. Slide rods 11 are fixedly penetrated inside the two baffles 6. The slide rods 11 are slidably arranged in the slide holes 10.

[0026] When the treatment device 1 is performing exhaust gas treatment, the left dust filter 5 is arranged in the treatment device 1. At this time, the exhaust gas enters the treatment device 1 through the intake pipe 2, and the large particle impurities inside the exhaust gas are preliminarily cleaned through the dust filter 5. Then the low-temperature plasma device 4 is started to perform fine treatment on the exhaust gas. After the exhaust gas treatment, the gas flows outward through the exhaust pipe 3. When the exhaust gas treatment is performed for a long time, the adjustment plate 8 can be rotated so that the adjustment plate 8 rotates around the support rod 9. In this process, the slide bar 11 and the slide hole 10 cooperate to enable the slide bar 11 to drive the upper baffle 6 to move longitudinally, so that the two dust filters 5 can be switched. At this time, the right dust filter 5 enters the treatment device 1, and the left dust filter 5 moves out of the reaction device 1. After the position of the dust filter 5 is determined, the dust on the surface of the dust filter 5 outside the reaction device 1 can be cleaned, so that the dust filter 5 can be used continuously for many times to improve the exhaust gas treatment effect.

[0027] In order to be able to fix the position of the dust filter 5 after the positions of the two dust filter screens 5 are switched, as shown in FIG. Figure 2-3 As shown, a fixing plate 12 is fixedly provided at the rear end of the support rod 9, a sliding plate 13 is slidingly sleeved on the rod wall of the support rod 9, positioning rods 14 are fixedly penetrated at both ends of the sliding plate 13, a plurality of symmetrically arranged positioning grooves 15 are provided on the back side of the adjusting plate 8, the positioning rod 14 passes through the adjusting plate 8 and is inserted into the positioning groove 15, a spring 16 is sleeved on the rod wall of the support rod 9, and both ends of the spring 16 are fixedly connected to the adjusting plate 8 and the fixing plate 12 respectively, and a drawing groove 18 is provided on the side wall of the positioning rod 14.

[0028] Before switching the two dust filters 5, the two positioning rods 14 are pulled through the pull grooves 18, so that the positioning rods 14 drive the slide plate 13 to move and squeeze the spring 16. At this time, the positioning rod 14 is away from the positioning groove 15, and then the adjustment plate 8 can be rotated to drive the two dust filters 5 to switch positions. After the position of the dust filter 5 is determined, the positioning rod 14 is released. Under the elastic force of the spring 16, the slide plate 13 drives the positioning rod 14 to be inserted into the positioning groove 15 again, and the position of the adjustment plate 8 and the dust filter 5 is determined to ensure stable exhaust gas treatment.

[0029] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
