Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically to an activated carbon adsorption device for waste gas. Background Technology

[0002] Waste gas refers to harmful gases generated during industrial production, transportation, and agricultural activities. It usually needs to undergo a series of treatments such as filtration and adsorption before being released into the atmosphere. The treatment of waste gas generated during the preparation of 2,4-dichloro-5-fluorobenzoyl chloride is of paramount importance.

[0003] Currently, when treating waste gas, the waste gas is usually introduced into an adsorption filter box, where activated carbon adsorbs and filters the waste gas. Then, the filtered gas is introduced into the subsequent process through the exhaust port for further treatment.

[0004] In the existing technology, filter boxes can be roughly divided into drawer type and top-loading bottom-discharge type filter boxes. When replacing the activated carbon in the filter screen of the top-loading bottom-discharge type filter box, the discharge port at the bottom of the box is usually opened to discharge the activated carbon in the filter element. After discharge, the discharge port at the bottom is closed, the inlet port at the top of the box is opened, and new activated carbon is filled into the box.

[0005] However, during the process of adding activated carbon, there is no component to buffer the falling speed of the activated carbon. When the activated carbon falls directly from a height to the bottom of the box, the impact force generated by gravity may cause the particles to break or the surface to become pulverized, resulting in dust flying around. Furthermore, the fine powder after breakage may clog the filter element pores and reduce the adsorption efficiency.

[0006] Therefore, it is necessary to provide an activated carbon adsorption device for waste gas to solve the above problems.

[0007] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0008] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide an activated carbon adsorption device for waste gas, which achieves the effect of buffering the activated carbon when it falls.

[0009] To solve the above-mentioned technical problems, the technical solution of this utility model is: a waste gas activated carbon adsorption device, including a housing; a filter assembly, which is disposed inside the housing, the filter assembly including: at least two sets of skeleton frames, which are installed inside the housing, and at least two sets of perforated plates are provided on the skeleton frames, the perforated plates having mesh holes; at least two sets of feeding plates, which are disposed below the perforated plates and are inclined; at least two sets of buffer plate groups, which are disposed on the perforated plates; wherein: the buffer plate group has two sets of inclined plates arranged alternately.

[0010] Furthermore, the top of the box is provided with at least two sets of inlets, the bottom of the box is provided with at least two sets of outlets, and both the outlets and inlets are provided with sealing doors. The buffer plate group is located between the inlet and the discharge plate.

[0011] Furthermore, an air inlet is provided at one end of the enclosure, and an air outlet is installed at the other end of the enclosure. Connecting plates are provided between at least two sets of frame frames.

[0012] Furthermore, the interior of the box is equipped with a striking assembly, which includes at least two sets of fixing boxes installed on the bottom wall of the box. The fixing boxes are located below the material feed plate, and the interior of the fixing boxes has cavities.

[0013] Furthermore, a motor is installed on the fixed box, and a rotating shaft is installed at the output end of the motor. The rotating shaft is rotatably installed inside the fixed box, and a turntable is installed at one end of the rotating shaft. The turntable is located inside the cavity.

[0014] Furthermore, the fixed box has two sets of push rods that slide inside, and a slider is installed at one end of both sets of push rods. The slider has a groove.

[0015] Furthermore, a fixing rod is provided at a position away from the center of the turntable, and part of the fixing rod is slidably disposed inside the slide groove. A main gear is fixedly sleeved on the rotating shaft, and the main gear is located on one side of the turntable.

[0016] Furthermore, a rotating rod is rotatably mounted on the fixed box, with a secondary gear fixedly sleeved at one end of the rotating rod. The secondary gear meshes with the main gear, and a cam is fixedly mounted at the other end of the rotating rod.

[0017] By adopting the above technical solution, this utility model has the following beneficial effects: by setting up the buffer plate group, the activated carbon will first come into contact with the buffer plate group when it falls from the feed inlet, and then gradually and slowly fall into the bottom of the mesh plate through the inclined surface of the buffer plate group, so that it is stored between each set of mesh plates, thereby achieving the effect of buffering the activated carbon when it falls.

[0027] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0028] like Figure 1 and Figure 3 As shown, this application provides an activated carbon adsorption device for waste gas, including a housing 1, which is assembled from multiple sets of plates. A filter assembly 2 is installed inside the housing 1. This filter assembly 2 is used to adsorb impurities in the waste gas. Specifically:

[0029] The filter assembly 2 includes an air inlet 21 fixedly installed at one end of the housing 1. The air inlet 21 is adapted to be connected to the exhaust gas pipeline in the previous process to introduce the exhaust gas into the housing 1 for adsorption and filtration. An air outlet 22 is fixedly installed at the other end of the housing 1. The air outlet 22 is adapted to be connected to the processing equipment in the next process to introduce the filtered exhaust gas into the subsequent processing equipment.

[0030] Multiple sets of feed inlets 23 are provided at the top of the box 1 to facilitate the introduction of activated carbon into the box 1 through the feed inlets 23 during feeding. Multiple sets of discharge outlets 29 are provided at the bottom of the box 1 to facilitate the discharge of activated carbon from the discharge outlets 29. Both the discharge outlets 29 and the feed inlets 23 are equipped with sealing doors (not shown in the figure) to seal the discharge outlets 29 and the feed inlets 23.

[0031] like Figures 2-3 As shown, multiple sets of vertically arranged skeleton frames 25 are fixedly installed inside the box 1. The four perimeters of each skeleton frame 25 are provided with perforated plates 26 to enclose the four perimeters of the skeleton frame 25.

[0032] Furthermore, there is a gap between adjacent perforated plates 26 to form a storage area. The upper and lower ends of the storage area are not closed. The upper and lower ends of the storage area are located at the inlet 23 and the outlet 29, respectively, so that activated carbon can be introduced into the interior of the skeleton frame 25 through the inlet 23, stored in the storage area through the perforated plates 26, and discharged from the outlet 29 during discharge.

[0033] The perforated plate 26 has multiple sets of mesh holes to facilitate the passage of introduced gas and its contact with activated carbon. Under the adsorption of activated carbon, impurities inside the gas are adsorbed and discharged to the next process through the mesh holes and the gas outlet 22.

[0034] A connecting plate 24 is installed between multiple sets of skeleton frames 25 to connect the skeleton frames 25, thereby improving the stability of the skeleton frames 25. In each storage area, multiple sets of feeding plates 28 are fixedly installed below the mesh plate 26. The feeding plates 28 are inclined, and the upper end of the feeding plates 28 is fixedly connected to the mesh plate 26. The lower end of the feeding plates 28 is set at the discharge port 29 so that the activated carbon can fall more smoothly under the action of the inclined surface of the feeding plates 28 when it is discharged.

[0035] Multiple sets of buffer plate groups 27 are provided above the feed plate 28. Each buffer plate group 27 consists of two sets of symmetrical and staggered inclined plates, and the buffer plate group 27 is located below the feed inlet 23.

[0036] Thus, when activated carbon is fed through the feed inlet 23, it is buffered by two sets of inclined plates before falling, which slows down its falling speed and avoids the impact force generated by gravity when it falls freely from a height to the bottom of the box 1, which may cause the particles to break or the surface to pulverize.

[0037] Inside the housing 1, there is a striking component 3, which is adapted to strike the mesh plate 26, thereby shaking off the material clogging the mesh when the activated carbon is discharged.

[0038] like Figures 3-5As shown, the striking component 3 includes multiple sets of fixing boxes 31 fixedly installed on the bottom wall of the housing 1. The fixing box 31 is located below the material feeding plate 28, and the interior of the fixing box 31 has a cavity (not shown in the figure). A motor 32 is fixedly installed on the fixing box 31.

[0039] The output end of the motor 32 is fixedly mounted with a rotating shaft, which is rotatably mounted inside the fixed box 31. One end of the rotating shaft is fixedly mounted with a turntable 37, which is located inside the cavity. Thus, under the drive of the motor 32, the rotating shaft is driven to rotate, which in turn drives the turntable 37 to rotate inside the cavity.

[0040] Two sets of push rods 35 are slidably arranged inside the fixed box 31. A slider 36 is fixedly installed at one end of the two sets of push rods 35. A sliding groove is opened on the slider 36. A fixed rod 371 is arranged at a position away from the center of the turntable 37. Part of the fixed rod 371 is slidably arranged inside the sliding groove.

[0041] In the initial state, the fixed rod 371 is located at the upper end of the chute. When the turntable 37 rotates continuously, it drives the fixed rod 371 to rotate back and forth, thereby driving the fixed rod 371 to move from the upper end to the lower end in the chute in a back-and-forth cycle, which in turn drives the two sets of top rods 35 to move back and forth left and right, thereby knocking on the mesh plates 26 on both sides, so that the material blocked on the mesh plates 26 falls off.

[0042] A main gear 39 is fixedly sleeved on the rotating shaft. The main gear 39 is located on one side of the turntable 37. A rotating rod 33 is rotatably mounted on the fixed box 31. A secondary gear 38 is fixedly sleeved on one end of the rotating rod 33. The secondary gear 38 and the main gear 39 are meshed and connected. Both the secondary gear 38 and the main gear 39 are located inside the cavity. Thus, when the rotating rod 33 rotates, it synchronously drives the main gear 39 to rotate, which in turn drives the secondary gear 38 and the rotating rod 33 to rotate.

[0043] A cam 34 is fixedly installed at the other end of the rotating rod 33. The cam 34 is located below the feed plate 28, so that when the rotating rod 33 rotates, the cam 34 is driven to rotate synchronously.

[0044] It should be noted that the protrusion of the cam 34 is made of elastic material, and when the cam 34 rotates to the vertical position, it will contact the bottom of the feed plate 28, thereby reciprocatingly striking the feed plate 28, which can accelerate the falling speed of the activated carbon when it is discharged.

[0045] In summary, when feeding, open the closed door of the feed inlet 23 and feed the activated carbon into the feed inlet 23. The activated carbon entering the mesh plate 26 will come into contact with multiple sets of buffer plates 27 in succession, so that the feeding speed is buffered. This avoids the activated carbon from falling directly from a height to the bottom of the box 1, which may cause the particles to break or the surface to pulverize due to the impact force generated by gravity acceleration. After feeding is completed, close the closed door and use it.

[0046] In use, the exhaust gas is introduced through the air inlet 21 and enters the mesh plate 26 through the mesh, where it comes into contact with activated carbon to adsorb impurities in the exhaust gas. The adsorbed gas is then discharged through the mesh of the mesh plate 26 and enters the subsequent equipment for treatment through the exhaust port.

[0047] When the activated carbon needs to be replaced after a long period of use, open the closed door of the discharge port and the activated carbon will be discharged from the discharge port. At the same time, start the striking component 3 to strike the mesh plate 26, so that the material blocking the mesh of the mesh plate 26 is vibrated and dislodged. At the same time, strike the discharge plate 28 to speed up the discharge of activated carbon.

[0048] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
