Description

Technical Field

[0001] The utility model relates to the technical field of waste gas absorption devices, and specifically to an organic waste gas absorption device. Background Art

[0002] Air pollution is currently a prominent environmental problem in my country, and industrial waste gas is the main source of air pollution. A large amount of industrial waste gas is discharged into the air, which not only pollutes the environment, but also endangers people's health. In order to control air pollution, the country will temporarily stop some industrial production departments, which also causes certain losses to the national economy. The most difficult to deal with industrial waste gas is organic waste gas, and these organic waste gases mainly include hydrocarbons, aldehydes, acids, amines, etc. The emission of these organic waste gases not only endangers people's health, but also causes waste of resources. Therefore, the treatment of organic waste gas has always been the focus and difficulty of people's attention. In the process of organic waste gas treatment, due to the relatively simple structure of the existing organic waste gas absorption device, when the internal filter structure of the device needs to be cleaned or replaced, the filter structure needs to be disassembled once, but the existing organic waste gas absorption device is more troublesome to disassemble and install, and the practicality is poor.

[0003] After searching, the existing patent (publication number: CN216604694U) discloses an organic waste gas absorption device, which includes a first processing shell, a second processing shell, a third processing shell and an easy-to-disassemble component. The lower edge of the first processing shell is fixed with a first processing shell annular connecting plate, the upper edge and the lower edge of the second processing shell are respectively fixed with a second processing shell upper side annular connecting plate and a second processing shell lower side annular connecting plate, and the upper edge of the third processing shell is fixed with a third processing shell annular connecting plate. The utility model can make the disassembly or installation between the first processing shell, the second processing shell and the third processing shell more convenient and quick, and thus facilitate the cleaning of the exhaust gas particle filter and the activated carbon adsorption layer after long-term work.

Among them, the waste gas filter component 4 includes two filter components 41, and the two filter components 41 are connected by a limiting middle plate 42. The arrangement of the two filter components 41 enables the filter components 41 to work alternately inside the treatment frame 1, which is convenient for rapid replacement of waste gas treatment materials.

[0031] See also Figure 2 , Figure 3 , Figure 4 as well as Figure 5 The filter component 41 includes a first filter frame 411 and a second filter frame 413. One end of the first filter frame 411 is fixedly connected to the limiting middle plate 42. The lower side of the other end of the first filter frame 411 is rotatably connected to the second filter frame 413 through a rotating shaft 412. The end of the second filter frame 413 away from the limiting middle plate 42 is fixedly connected to a push-pull outer plate 414, and the end of the push-pull outer plate 414 away from the second filter frame 413 is fixedly connected to a handle 415. Under the action of the rotating shaft 412, the second filter frame 413 can be flipped downward from a horizontal state, while the second filter frame 413 cannot be flipped upward from a horizontal state. The first filter frame 411 and the second filter frame 413 placed horizontally can stably contain materials such as activated carbon for waste gas treatment. In the actual working process, a mesh plate can also be equipped to cover the upper side of the material.

[0032] Two splicing strips 105 are symmetrically fixed on the processing frame 1. A through slot 103 is provided on the processing frame 1 located at the lower side of the splicing strip 105, for sliding the first filter frame 411 and the second filter frame 413, so that the two first filter frames 411 can work alternately inside the processing frame 1. The limiting middle plate 42 is slidably connected to the inside of the processing frame 1 and is located between the two splicing strips 105. A lap groove 104 is provided on the outer wall of the processing frame 1 located on one side of the splicing strip 105, for bridging the push-pull outer plate 414. Fixed grooves 101 are provided on the outer wall of the processing frame 1 located on both sides of the lap groove 104, for bridging the fixed block 417, and bolt holes 102 matching the fastening bolts 416 are provided inside the fixed groove 101. Two fixed blocks 417 are symmetrically fixed on the push-pull outer plate 414, and fastening bolts 416 are threadedly connected inside the two fixed blocks 417. Under the combined action of the fastening bolts 416 and the bolt holes 102 , one of the filter components 41 can be stably fixed inside the processing frame 1 .

[0033] See also Figure 1 , Figure 2 as well as Figure 6 , a plurality of protection frames 5 are arranged on the outer wall of the processing frame 1, and the protection frames 5 correspond to the exhaust gas filter components 4 one by one, and are used to protect the filter components 41 on the exhaust gas filter components 4 that are outside the processing frame 1. The protection frame 5 includes a fixed frame 53 fixedly connected to the outer wall of the processing frame 1, and the lower end of the fixed frame 53 is in an open state. A baffle 51 is slidably arranged on the outer wall of the fixed frame 53 away from the processing frame 1, and a handle 52 is fixed on the outer wall of the baffle 51. A slide groove 55 is opened on the outer wall of the fixed frame 53 on the side close to the baffle 51, and a slide rod 54 is fixed on the outer wall of the baffle 51 on the side close to the fixed frame 53, and the slide rod 54 slides and fits with the slide groove 55. The cross-sectional shapes of the slide rod 54 and the slide groove 55 are both T-shaped. Under the joint action of the sliding rod 54 and the sliding groove 55, the baffle 51 can slide smoothly on the fixed frame 53 through the handle 52, and the friction between the sliding rod 54 and the sliding groove 55 is greater than the sum of the gravity of the baffle 51 and the handle 52, so that the baffle 51 can stay at any position on the fixed frame 53. The port of the fixed frame 53 away from the processing frame 1 is closed by the baffle 51, and the filter component 41 on the inner side of the fixed frame 53 can be shielded and protected.

[0034] Working principle and use process: When working, one filter component 41 of the exhaust gas filter assembly 4 is placed inside the processing frame 1, and the other filter component 41 is located outside the processing frame 1 (refer to Figure 3), the filter component 41 inside the processing frame 1 contains materials such as activated carbon for waste gas treatment. At this time, the push-pull outer plate 414 on the filter component 41 inside the processing frame 1 is laid in the overlap groove 104, and the limit middle plate 42 is laid on the side of the splicing bar 105 close to the inside of the processing frame 1. The filter component 41 is stably fixed inside the processing frame 1 by fastening bolts 416 and bolt holes 102. The filter component 41 outside the processing frame 1 can flip the second filter frame 413 downward from a horizontal state under the action of the rotating shaft 412 (refer to Figure 2 ), at this time, the port of the fixed frame 53 away from the processing frame 1 is closed by the baffle 51, so that the filter component 41 inside the fixed frame 53 can be shielded and protected. After a long period of waste gas treatment, when it is necessary to replace the material on the filter component 41 inside the processing frame 1, the new material is placed on the filter component 41 outside the processing frame 1 in advance, and the filter component 41 is pushed into the processing frame 1. During this process, the filter component 41 originally located inside the processing frame 1 will be pushed out synchronously, so as to realize the rapid replacement of the two filter components 41. In addition, it is convenient to clean and organize the filter component 41 located on the outside.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
