Description

Technical Field

[0001] The utility model relates to the technical field of tail gas treatment, in particular to a tail gas recovery adsorber used for chemical activated carbon production. Background Art

[0002] Activated carbon is a porous carbonaceous material that is used in many industries for its wide range of adsorption properties. Activated carbon is a specially treated carbon, which is mainly made through two steps of carbonization and activation. It can adsorb various organic and inorganic compounds from gaseous or liquid media to separate the mixture, or be used to remove pollutants to purify air or water. The physical and chemical properties of activated carbon make it a preferred material in many industrial and environmental applications. Exhaust gas is produced during the processing of activated carbon. The exhaust gas contains carbon powder, and the exhaust gas needs to be processed through a recovery adsorber.

[0003] At present, when treating the exhaust gas, the exhaust gas is introduced into the front-end collecting box of the adsorber, the carbon powder is collected after being isolated by the filter, and the gas is treated by the rear-end adsorber and then discharged.

[0004] Although the above working method can complete the separation of solid and gas impurities, it also has the following problems: since the exhaust gas treatment is in a continuous working state, the above filter needs to be cleaned after working for a period of time to prevent carbon powder from clogging the filter and thus affecting the subsequent air intake efficiency. Manual intervention is required for multiple maintenance of the filter and collection of the scattered carbon powder, which increases the difficulty of manual collection and is not convenient for use in actual work.

[0005] In view of this, this application is hereby filed. Utility Model Content

[0006] The purpose of the utility model is to provide a tail gas recovery adsorber for chemical activated carbon production to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the utility model provides a tail gas recovery adsorber for chemical activated carbon production, comprising: a box body, an air inlet pipe, an exhaust pipe, and a filter box;

[0008] An intake pipe and an exhaust pipe are respectively installed on the front end face and the rear end face of the box body. An intake box is installed at the end of the intake pipe located on the inner wall of the box body. An intake hose is installed on the rear end face of the intake box. There are two groups of intake hoses arranged at intervals. The intake hoses are communicated with the front end face of the filter box. The filter box is integrally arranged in an arched structure, with a top surface and an arc surface structure. A filter screen plate is installed on the rear end face of the filter box. The rear end face of the filter screen plate is hermetically connected to the exhaust hose of the exhaust pipe. There are two groups of exhaust hoses arranged at intervals. The exhaust hoses are communicated with the exhaust box. A lead-out pipe is installed at the bottom of the filter box. The upper part of the lead-out pipe is a rectangular structure with a tapered setting, and the lower part is a rectangular pipe structure.

[0009] In one embodiment, a partition is installed at the lower part inside the box body. There is a spacing between the inner top surface of the partition and the bottom surface of the box body, and an independent sealed cavity is formed therebetween. There is a liquid injection pipe and a liquid discharge pipe outside the cavity. Water is pre-injected into the inside of the partition. There is a spacing between the water surface and the top surface of the partition. A notch is opened in the middle of the top surface of the partition. The bottom end of the lead-out pipe penetrates through the notch and extends above the water surface.

[0010] In one embodiment, rubber stop strips are installed at intervals on the inner wall of the notch. The rubber stop strips are used to block the dispersion of toner, and at the same time can provide an unobstructed moving path for the lead-out pipe.

[0011] In one embodiment, there are two groups of filter boxes arranged at intervals. The top surface of the filter box is obliquely installed and connected to the installation pipe through a connecting rod. The installation pipe is sleeved on the installation shaft. The installation shaft is installed on the front and rear end faces of the upper part inside the box body. Gears are installed on both sides of the installation pipe.

[0012] In one embodiment, a cylinder is installed on the right top surface of the box body. The cylinder is installed and connected to a push rod. The left end of the push rod is installed and connected to a fixed rod. The bottom surface of the fixed rod penetrates through the first limit groove on the top surface of the box body and is installed and connected to a rack. The tooth surface of the rack is meshed with the gear.

[0013] In one embodiment, contact heads are installed on the inner wall surfaces of both sides of the box body. The contact heads are arranged oppositely. The contact heads and the middle part of the lead-out pipe are in the same plane.

[0014] In one embodiment, a vertical rod is installed laterally at the bottom of the fixed rod. The bottom of the vertical rod penetrates through the second limit groove on the top surface of the partition and is connected to a stirring plate. The stirring plate is integrally in a corrugated plate structure. Two groups of stirring plates are arranged in a relatively inclined manner.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] 1. Through the structural settings of the filter box and the outlet pipe, it helps to quickly discharge the toner from the filtering range of the filter screen plate, and it falls along the inclined wall surface, eliminating the need for manual cleaning operations multiple times and avoiding the problem of filter screen blockage during continuous operation.

[0017] 2. The cylinder drives the push rod and the fixed rod to reciprocate within the first limit groove, and then drives the rack to drive the gear to rotate reciprocally, synchronously driving the installation shaft and the installation pipe to rotate, causing the lower filter box and the outlet pipe to swing intermittently and reciprocally. This makes the filtered toner accelerate its fall under the action of the swing, preventing it from accumulating at the filter screen plate. At the same time, the swing of the outlet pipe helps to evenly distribute the toner in the water below the partition, restricting the dispersion path.

[0018] 3. When the outlet pipe swings, it continuously contacts the contact head, generating small-amplitude vibrations on the wall surface of the outlet pipe, which helps to increase the falling speed of the toner and reduce the possibility of the toner adhering to the wall surface. The vertical rod continuously moves under the drive of the fixed rod, causing the stirring plate to form fluctuations in the water, which helps the toner to quickly dissolve in the water.

[0026] The front end face and the rear end face of the box body 1 are respectively installed with an intake pipe 2 and an exhaust pipe 3. The end of the intake pipe 2 located on the inner wall of the box body 1 is installed with an intake box 21. The rear end face of the intake box 21 is installed with an intake hose 22.

The filter box 4 is arranged in an arched structure as a whole, and its top surface is a curved surface structure. The rear end face of the filter box 4 is installed with a filter plate 41. The rear end face of the filter plate 41 is sealed with the exhaust hose 32 of the exhaust pipe 3. The exhaust hose 32 is connected, and two groups of them are arranged at intervals. The exhaust hose 32 is connected to the exhaust box 31. A derivation pipe 42 is installed at the bottom of the filter box 4. The upper part of the derivation pipe 42 is a tapered rectangular structure, and the lower part is a rectangular tube structure. The exhaust gas containing carbon powder is transported from the intake pipe 2 to the inside of the filter box 4, and after being filtered by the filter screen 41, the carbon powder falls into the derivation pipe 42 below, and gradually moves downward along the extension path of the derivation pipe 42. After the powder is removed, the exhaust gas is discharged from the exhaust pipe 3 to the gas adsorber for treatment.

[0027] Preferably, in one embodiment, Figures 2-3 As shown, a partition 5 is installed at the lower part of the box body 1, and a gap is left between the inner top surface of the partition 5 and the bottom surface of the box body 1, forming an independent sealed cavity therebetween. An injection pipe and a discharge pipe are provided outside the cavity. Water is pre-injected into the interior of the partition 5, and a gap is left between the water surface and the top surface of the partition 5. A notch 51 is provided in the middle of the top surface of the partition 5, and the bottom end of the outlet pipe 42 passes through the notch 51 and extends above the water surface, which helps to fuse the falling carbon powder with water to prevent the carbon powder from floating.

[0028] Preferably, in one embodiment, Figures 2-3 As shown, rubber baffles 52 are installed at intervals on the inner wall of the notch 51 . The rubber baffles 52 are used to prevent carbon powder from scattering and provide an unobstructed moving path for the outlet pipe 42 .

[0029] Preferably, in one embodiment, Figures 2-3As shown, there are two groups of filter boxes 4 arranged at intervals. The top surface of the filter box 4 is obliquely installed and connected to the installation pipe 62 through the connecting rod 61. The installation pipe 62 is sleeved on the installation shaft 63. The installation shaft 63 is installed on the front and rear end faces of the upper part inside the box body 1. Gears 64 are installed on both sides of the installation pipe 62.

[0030] Preferably, in one embodiment, as Figures 2-3 shown, a cylinder 71 is installed on the top surface of the right side of the box body 1. The cylinder 71 is installed and connected to the push rod 72. The left end of the push rod 72 is installed and connected to the fixed rod 73. The bottom surface of the fixed rod 73 penetrates through the first limit groove 11 on the top surface of the box body 1 and is installed and connected to the rack 74. The tooth surface of the rack 74 is meshed and connected with the gear 64. During operation, the cylinder 71 drives the push rod 72 and the fixed rod 73 to reciprocate in the first limit groove 11, and then drives the rack 74 to drive the gear 64 to rotate reciprocally, synchronously driving the installation shaft 63 and the installation pipe 62 to rotate, so that the lower filter box 4 and the outlet pipe 42 swing intermittently and reciprocally, accelerating the falling of the filtered toner under the swinging action, avoiding accumulation at the filter screen plate 41, and at the same time, the swinging of the outlet pipe 42 helps to evenly distribute the toner in the water below the partition plate 5 and limit the dispersion path.

[0031] Preferably, in one embodiment, as Figures 2-3 shown, contact heads 8 are installed on the inner wall surfaces of both sides of the box body 1. The contact heads 8 are arranged oppositely. The contact heads 8 and the middle part of the outlet pipe 42 are in the same plane. When the outlet pipe 42 swings, it continuously contacts the contact heads 8, generating small-amplitude vibrations on the wall surface of the outlet pipe 42, which helps to increase the falling speed of the toner and reduce the possibility of the toner adhering to the wall surface.

[0032] Preferably, in one embodiment, as Figures 3-4 shown, a vertical rod 75 is laterally installed at the bottom of the fixed rod 73. The bottom of the vertical rod 75 penetrates through the second limit groove 53 on the top surface of the partition plate 5 and is connected to the stirring plate 76. The stirring plate 76 is integrally in a corrugated plate structure. The two stirring plates 76 are arranged in a relatively inclined state. During operation, as the toner enters the water, the vertical rod 75 continuously displaces under the drive of the fixed rod 73, causing the stirring plate 76 to form fluctuations in the water, which helps the toner to quickly dissolve in the water.

[0033] Working principle:

[0034] During operation, the tail gas containing toner is transported from the intake pipe 2 to the interior of the filter box 4. After being filtered by the filter mesh plate 41, the toner falls into the lower discharge pipe 42 and gradually moves downward along the extension path of the discharge pipe 42. The tail gas is discharged to the gas adsorber for treatment after powder removal through the exhaust pipe 3. The push rod 72 and the fixed rod 73 are reciprocally displaced in the first limit groove 11 by the cylinder 71, thereby driving the rack 74 to drive the gear 64 to rotate reciprocally, synchronously driving the mounting shaft 63 and the mounting pipe 62 to rotate, causing the lower filter box 4 and the discharge pipe 42 to swing intermittently and reciprocally. This causes the filtered toner to accelerate its fall under the action of the swing, preventing it from accumulating at the filter mesh plate 41. At the same time, the swing of the discharge pipe 42 helps to evenly distribute the toner in the water below the partition plate 5, restricting the dispersion path. As the toner enters the water, the vertical rod 75 is continuously displaced under the drive of the fixed rod 73, causing the stirring plate 76 to form waves in the water, which helps the toner to quickly dissolve in the water.
