Description

Technical Field

[0001] The present invention belongs to the technical field of tail gas treatment, and particularly relates to an activated carbon tank for tail gas treatment. Background Art

[0002] An activated carbon tank for tail gas treatment is a device for purifying tail gas, including a tank body, an activated carbon layer, an air inlet, an air outlet, a support and fixing device, and a monitoring and control system. Among them, the activated carbon layer is the core part of the activated carbon tank, which is formed by piling granular or columnar activated carbon. To ensure the adsorption effect, the activated carbon layer needs to have a certain thickness and density, and the appropriate type and specification of activated carbon should be selected according to the flow rate and composition of the treated tail gas. The air inlet is located at one end of the activated carbon tank to enable the tail gas to enter the tank evenly; the air outlet is located at the other end, and the purified tail gas is discharged from here. Airflow distribution devices, such as perforated plates, guide plates, etc., are usually installed at the air inlet and air outlet to ensure the uniform flow of the tail gas in the activated carbon tank and full contact with the activated carbon.

[0003] After the tail gas treatment device is used for a period of time, the activated carbon of the device needs to be replaced regularly to ensure the normal use of the device. In actual replacement, the original activated carbon tank is installed under the device and fixed by nuts, which requires the staff to disassemble it from under the device, resulting in inconvenient operation and a long replacement time. Summary of the Invention

[0004] In order to solve the above problems, the present invention proposes an activated carbon tank for tail gas treatment to more precisely solve the above-mentioned problems.

[0005] The present invention is achieved through the following technical solutions: The present invention proposes an activated carbon tank for tail gas treatment, including a box body. A square through groove is provided on the box body. A shell is slidably arranged in the box body. Two placement boxes are placed in the shell. Activated carbon particles are placed in the placement boxes. Honeycomb plates are installed on both sides of all the placement boxes. Circular tubes are communicated with both sides of the shell. Two square through grooves are provided on one side of the placement box. A discharge port is provided on one side of each of the two shells, and the discharge port is opposite to the square through groove. A first baffle is slidably connected to the side wall of the square through groove. A feeding port is provided on the side wall of the placement box above the discharge port, and the feeding port is opposite to the square through groove. A second baffle is slidably connected in the square through groove, and the second baffle is located above the first baffle.

[0006] In one example, inclined plates are fixedly connected to the interiors of both of the two placement boxes, and the inclined plates incline towards the discharge port. A fixing plate is fixedly connected to the lower surface of the second baffle, and a fastening bolt is threadedly connected to the fixing plate.

[0007] In one example, both sides of the box body are connected to connecting pipes. Slide pipes are slidably connected to the connecting pipes. The inner diameter of the slide pipes is the same as the outer diameter of the circular pipes. Support plates are fixedly connected to the outer sides of the slide pipes. The inner wall of the box body is fixedly connected to a mounting plate. One side of the support plate is fixedly connected to a fixing rod. The fixing rod passes through the mounting plate and is slidably connected to the mounting plate. A spring is fixedly connected between the support plate and the mounting plate.

[0008] In one example, fixing blocks are fixedly connected to both sides of the box body. The thickness of the fixing blocks is less than the length of the circular pipes. A chute is provided on one side of each fixing block. Slide blocks are slidably connected in the chutes. One side of each slide block is arc-shaped. The upper end of the chute is at the same height as the upper surface of the support plate. The length of the slide block is greater than the width of the support plate. The upper and lower sides of the support plate are arc-shaped. Steel cables are fixedly connected to the upper surfaces of the slide blocks. The steel cables pass upward through the fixing blocks and the housing.

[0009] In one example, the upper ends of the two steel cables on the same side of the housing are fixedly connected to a cross bar. A hanging ring is fixedly connected to the cross bar.

[0010] In one example, conical pipes are fixedly connected to the outer sides of the two slide pipes. The outer side of the conical pipe is an inclined surface, and the inclined surface inclines towards the circular pipe.

[0011] In one example, a fixing pipe is fixedly connected between two honeycomb plates on one of the placement boxes. The fixing pipe passes through the two honeycomb plates and the placement box. A support plate is fixedly connected to the inner wall of the fixing pipe. An electric push rod is fixedly connected to one side of the support plate. One end of the electric push rod is fixedly connected to a circular plate. The radius of the circular plate is the same as the inner diameter of the fixing pipe. The circular plate is close to the circular pipe on the side of the housing.

[0012] In one example, a support rod is fixedly connected to one side of the circular plate. A shielding plate is arranged between the two placement boxes. A circular through groove is provided on the shielding plate. The radius of the circular through groove is less than the radius of the fixing pipe. The support rod passes through the fixing pipe and the circular through groove. One end of the support rod is bent and fixedly connected to the shielding plate.

[0013] The activated carbon tank for tail gas treatment proposed by the present invention can bring the following beneficial effects: First, by slidably arranging a housing on the upper surface of the box body, a placement box is installed inside the housing. The housing is closely attached to the inner wall of the box body, and the placement box is closely attached to the inner wall of the housing. When the activated carbon needs to be replaced, lift the housing upward, pull the housing out of the box body, and expose the two square through grooves on one side of the housing. Then, lift the two first baffles on the housing to expose the discharge port. After the activated carbon rolls out through the discharge port and the square through grooves, release the first baffles. The first baffles slide downward under the action of gravity to block the discharge port. When new activated carbon particles need to be added, pull down the second baffle to expose the feeding port, and inject new activated carbon particles through the feeding port. When replacing the activated carbon particles, it is not necessary for the staff to go under the equipment for replacement, and the operation is more convenient and labor-saving; Second, by arranging sliding blocks, when replacing the activated carbon, the lifting equipment can hook the hanging ring to pull the housing upward. The hanging ring pulls the steel cable, and the steel cable pulls the sliding block to rise, so that the sliding seat is squeezed between the support plate and the fixed block, pushing open the support plate. The support plate drives the sliding tube to slide and separate from the circular tube. When the sliding block rises to the highest point of the sliding groove, the sliding block abuts against the fixed block, thereby driving the housing to rise and be pulled out of the box body. When the housing returns to its original position after replacing the activated carbon, the side of the bottom of the housing abuts against the conical tube, pushing the conical tube and the sliding tube away. During the descent, the sliding tube abuts against one side of the housing. During the descent, the circular tube abuts against the side wall of the conical tube, pushing the conical tube and the sliding tube away again, and the spring stores energy. When the bottom of the housing touches the box body, the circular tube and the sliding tube are opposite, and the sliding tube is sleeved outside the circular tube, automatically completing the docking of the sliding tube and the circular tube. The operation is simple and the use is convenient; Third, by arranging a circular plate and a shielding baffle, when the pollution degree of the tail gas to be purified is relatively high, the electric push rod pulls the circular plate to block the fixed tube. At the same time, the shielding baffle does not contact the placement box with the fixed tube. In this way, after the tail gas is purified by the front placement box, it bypasses the shielding baffle and passes through the placement box with the fixed tube for secondary purification, improving the treatment effect on the tail gas. When the pollution degree of the tail gas is relatively low, the electric push rod pushes the circular plate away from the fixed cylinder, and the shielding baffle blocks the honeycomb plate on one side of the placement box with the fixed tube, so that the tail gas passes through the front placement box for purification and then passes through the fixed tube to be discharged from the housing, saving time. In this way, the treatment efficiency of the tail gas can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0024] In order to more clearly illustrate the overall concept of the present invention, the following will be described in detail by way of examples in conjunction with the specification drawings.

[0025] Such as Figures 1 to 8As shown in the figure, an embodiment of the present invention provides an activated carbon tank for tail gas treatment, which includes a box body 1. A square through groove is provided on the box body 1. A housing 2 is slidably arranged in the box body 1. Two placement boxes 3 are placed in the housing 2. Activated carbon particles are placed in the placement boxes 3. Honeycomb plates 4 are installed on both sides of all the placement boxes 3. Circular tubes 5 are communicated with both sides of the housing 2. Two square through grooves are provided on one side of the placement box 3. Discharge ports are provided on one side of both housing 2s, and the discharge ports are opposite to the square through grooves. The side wall of the square through groove is slidably connected to a first baffle 6. A feeding port is provided on the side wall of the placement box 3 above the discharge port, and the feeding port is opposite to the square through groove. A second baffle 7 is slidably connected in the square through groove. The second baffle 7 is located above the first baffle 6. In this device, the activated carbon is placed in two placement boxes 3 in the housing 2. The placement boxes 3 are installed in the housing 2. The housing 2 is closely attached to the inner wall of the box body 1, and the placement boxes 3 are closely attached to the inner wall of the housing 2. Gas enters through the circular tube 5 on one side of the housing 2, and after being adsorbed and filtered by the activated carbon in the two placement boxes 3, it is discharged from the housing 2 through the circular tube 5 at the other end. When the activated carbon needs to be replaced, lift the housing 2 and pull out the housing 2 from the box body 1 to expose the two square through grooves on one side of the housing 2. Then lift the two first baffles 6 on the housing 2 to expose the discharge port, so that the activated carbon in the placement box 3 rolls out through the discharge port and the square through groove. The staff only needs to use a container to collect the activated carbon particles and clean the residue in the placement box 3. Then release the first baffle 6, and the first baffle 6 slides down under the action of gravity to block the discharge port. When new activated carbon particles need to be added, pull down the second baffle 7 to expose the feeding port, and inject new activated carbon particles through the feeding port. By sliding the housing 2 on the upper surface of the box body 1, when the activated carbon particles need to be replaced, it is not necessary for the staff to go to the lower part of the equipment for replacement, and the operation is more convenient and labor-saving.

[0026] As Figure 3 shown, Figure 4 Two inclined plates 8 are fixedly connected to the inside of both placement boxes 3. The inclined plates 8 are inclined towards the discharge port. A fixing plate 9 is fixedly connected to the lower surface of the second baffle 7. A fastening bolt is threadedly connected to the fixing plate 9. When discharging the used activated carbon particles in the placement box 3, the discharge port is exposed. Under the action of the inclined plate 8, the activated carbon particles have the inertia of sliding towards the discharge port, which promotes the discharge of the activated carbon through the discharge port, reduces the residue, and speeds up the replacement speed. The second fixing plate 9 is fixed by the fastening bolt. After the replacement of the activated carbon particles is completed, at this time, the second baffle 7 slides up to block the feeding port, and the fastening bolt is rotated to abut against one side of the housing 2 to fix the second baffle 7 and seal the activated carbon particles in the placement box 3 to prevent the second baffle 7 from descending under the action of gravity and exposing the feeding port.

[0027] As Figure 3 shown, Figure 4As shown in the figure, both sides of the box body 1 are connected to the connecting pipes 10. The sliding pipes 11 are slidably connected to the connecting pipes 10. The inner diameter of the sliding pipe 11 is the same as the outer diameter of the circular pipe 5. Support plates 12 are fixedly connected to the outer sides of the sliding pipes 11. The inner wall of the box body 1 is fixedly connected to the mounting plate 13. A fixing rod 14 is fixedly connected to one side of the support plate 12. The fixing rod 14 passes through the mounting plate 13 and is slidably connected to the mounting plate 13. A spring 15 is fixedly connected between the support plate 12 and the mounting plate 13. When the housing 2 is used inside the box body 1, at this time, the sliding pipe 11 on the connecting pipe 10 is pushed by the spring 15 to approach the circular pipe 5 and is sleeved on the outside of the circular pipe 5. Since the outer diameter of the circular pipe 5 is the same as the inner diameter of the sliding pipe 11, the circular pipe 5 is in close contact with the sliding pipe 11. The tail gas enters through the connecting pipe 10 on one side of the box body 1, passes through the circular pipe 5 and enters the box body 1, and contacts the activated carbon particles in the placement box 3 for filtration. The sliding pipe 11 is in close contact with the circular pipe 5 to prevent the tail gas from leaking. When the housing 2 slides out for activated carbon replacement, the sliding pipe 11 slides in the reverse direction to avoid, preventing the sliding pipe 11 from blocking the circular pipe 5 and causing the housing 2 to be unable to slide out.

[0028] As Figure 4 with Figure 5As shown, fixed blocks 16 are fixedly connected to both sides of the box body 1. The thickness of the fixed block 16 is less than the length of the circular tube 5. A chute is provided on one side of each fixed block 16, and a sliding block 17 is slidably connected in the chute. One side of the sliding block 17 is arc-shaped. The upper end of the chute is at the same height as the upper surface of the support plate 12. The length of the sliding block 17 is greater than the width of the support plate 12. The upper and lower sides of the support plate 12 are arc-shaped. Steel cables 18 are fixedly connected to the upper surfaces of the sliding blocks 17. The steel cables 18 penetrate upward through the fixed blocks 16 and the housing 2. The upper ends of the two steel cables 18 on the same side of the housing 2 are fixedly connected to a cross bar 19, and a hanging ring 20 is fixedly connected to the cross bar 19. Conical tubes 21 are fixedly connected to the outer sides of the two sliding tubes 11. The outer side of the conical tube 21 is an inclined surface, and the inclined surface inclines towards the circular tube 5. When replacing the activated carbon, a lifting device can be used to hook the hanging ring 20 and pull up the housing 2, so that the housing 2 is pulled out of the box body 1. When pulling out, the hanging ring 20 pulls the steel cable 18, and the steel cable 18 pulls the sliding block 17 to rise. The sliding block 17 contacts the support plate 12. Through the arc on one side of the sliding block 17 and the arc on the support plate 12, the sliding seat is squeezed between the support plate 12 and the fixed block 16, pushing open the support plate 12. The support plate 12 drives the sliding tube 11 to slide and separate from the circular tube 5. When the sliding block 17 rises to the highest point of the chute, the sliding block 17 abuts against the fixed block 16, and then drives the housing 2 to rise and be pulled out of the box body 1. By arranging the sliding block 17 and the support plate 12, when pulling out the housing 2, the sliding tube 11 can be automatically separated from the circular tube 5, which is more convenient to use. When the housing 2 is reset after replacing the activated carbon, the housing 2 descends under the action of gravity. The side at the bottom of the housing 2 abuts against the conical tube 21. As the housing 2 descends, the conical tube 21 and the sliding tube 11 are pushed open. When descending, the sliding tube 11 abuts against one side of the housing 2. During the descending process, the circular tube 5 abuts against the side wall of the conical tube 21, and the conical tube 21 and the sliding tube 11 are pushed open again. The spring 15 stores energy. When the bottom of the housing 2 contacts the box body 1, the circular tube 5 and the sliding tube 11 are opposite, but at this time the support plate 12 abuts against one side of the sliding block 17. At this time, the sliding block 17 is located at the top of the chute, and the support plate 12 abuts against the arc surface of the sliding block 17. Since the length of the sliding block 17 is greater than the width of the support plate 12, and the length of the sliding block 17 is greater than twice the width of the support plate 12, at this time the support plate 12 abuts against the upper arc surface of the arc surface on one side of the sliding block 17. Under the push of the spring 15, the support plate 12 squeezes the arc surface on one side of the sliding block 17, causing the sliding block 17 to descend and separate from the support plate 12, and then the support plate 12 abuts against one side of the fixed block 16. The sliding tube 11 is sleeved outside the circular tube 5, and the docking of the sliding tube 11 and the circular tube 5 is automatically completed, with simple operation and convenient use.

[0029] As Figure 6 , Figure 7 and Figure 8As shown, a fixed pipe 22 is fixedly connected between two honeycomb plates 4 on one of the placement boxes 3. The fixed pipe 22 passes through the two honeycomb plates 4 and the placement box 3. A support plate 23 is fixedly connected to the inner wall of the fixed pipe 22. An electric push rod 24 is fixedly connected to one side of the support plate 23. One end of the electric push rod 24 is fixedly connected to a circular plate 25. The radius of the circular plate 25 is the same as the inner diameter of the fixed pipe 22. A circular pipe 5 is on the side of the circular plate 25 close to the housing 2. A support rod 26 is fixedly connected to one side of the circular plate 25. A baffle plate 27 is arranged between the two placement boxes 3. A circular through groove is provided on the baffle plate 27. The radius of the circular through groove is smaller than the radius of the fixed pipe 22. The support rod 26 passes through the fixed pipe 22 and the circular through groove. One end of the support rod 26 is bent and fixedly connected to the baffle plate 27. During use, the placement box 3 with the fixed pipe 22 is located at the rear, so that the tail gas first passes through the placement box 3 without the fixed pipe 22 and then through the placement box 3 with the fixed pipe 22. In this way, during the use process, when the pollution degree of the tail gas to be purified is relatively high, the electric push rod 24 pulls the circular plate 25 into the fixed pipe 22 to block the fixed pipe 22. At the same time, the baffle plate 27 does not contact the placement box 3 with the fixed pipe 22. In this way, after the tail gas is purified by the front placement box 3, it bypasses the baffle plate 27 and passes through the placement box 3 with the fixed pipe 22 for secondary purification, improving the treatment effect on the tail gas. When the pollution degree of the tail gas is relatively low, the electric push rod 24 pushes the circular plate 25 away from the fixed cylinder. At the same time, the circular plate 25 pulls the baffle plate 27 through the support rod 26 to block the honeycomb plate 4 on one side of the placement box 3 with the fixed pipe 22, so that the tail gas passes through the front placement box 3 for purification and then is discharged from the housing 2 through the fixed pipe 22 and into the next placement box 3, saving time. In this way, the treatment efficiency of the tail gas can be improved.

[0030] Working principle: When replacing the activated carbon, the lifting device can be used to hook the hanging ring 20 and pull up the housing 2, so that the housing 2 is pulled out of the box body 1. When pulling out, the hanging ring 20 pulls the steel cable 18, and the steel cable 18 pulls the sliding block 17 to rise. The sliding block 17 contacts the support plate 12. Through the arc on one side of the sliding block 17 and the arc on the support plate 12, the sliding seat is squeezed into the space between the support plate 12 and the fixed block 16, pushing open the support plate 12. The support plate 12 drives the sliding tube 11 to slide and separate from the circular tube 5. When the sliding block 17 rises to the highest point of the chute, the sliding block 17 abuts against the fixed block 16, and then drives the housing 2 to rise and be pulled out of the box body 1. Lift the two first baffles 6 on the housing 2 to expose the discharge port, so that the activated carbon in the placement box 3 rolls out through the discharge port and the square through groove. The staff only needs to use a container to collect the activated carbon particles and clean the residue in the placement box 3. Then release the first baffle 6, and the first baffle 6 slides down under the action of gravity to block the discharge port. When it is necessary to supplement the activated carbon particles, pull down the second baffle 7 to expose the feeding port, and inject new activated carbon particles through the feeding port. When the housing 2 is reset after replacing the activated carbon, the housing 2 descends under the action of gravity, and the side at the bottom of the housing 2 abuts against the conical tube 21. As the housing 2 descends, the conical tube 21 and the sliding tube 11 are pushed open. During the descent, the sliding tube 11 abuts against one side of the housing 2. During the descent process, the circular tube 5 abuts against the side wall of the conical tube 21, and the conical tube 21 and the sliding tube 11 are pushed open again. The spring 15 stores energy. When the bottom of the housing 2 contacts the box body 1, the circular tube 5 and the sliding tube 11 are opposite, but at this time the support plate 12 abuts against one side of the sliding block 17. At this time, the sliding block 17 is located at the top of the chute, and the support plate 12 abuts against the arc surface of the sliding block 17. Since the length of the sliding block 17 is greater than the width of the support plate 12, and the length of the sliding block 17 is more than twice the width of the support plate 12, at this time the support plate 12 abuts against the upper arc surface of the arc surface on one side of the sliding block 17. Under the push of the spring 15, the support plate 12 squeezes the arc surface on one side of the sliding block 17, causing the sliding block 17 to descend and separate from the support plate 12, and then the support plate 12 abuts against one side of the fixed block 16, and the sliding tube 11 is sleeved outside the circular tube 5. When the pollution degree of the tail gas to be purified is relatively high, the electric push rod 24 pulls the circular plate 25 into the fixed tube 22 to block the fixed tube 22. At the same time, the shielding plate 27 does not contact the placement box 3 with the fixed tube 22. In this way, after the tail gas is purified by the front placement box 3, it bypasses the shielding plate 27 and passes through the placement box 3 with the fixed tube 22 for secondary purification, improving the treatment effect on the tail gas. When the pollution degree of the tail gas is relatively low, the electric push rod 24 pushes the circular plate 25 away from the fixed cylinder. At the same time, the circular plate 25 pulls the shielding plate 27 through the support rod 26 to block the honeycomb plate 4 on one side of the placement box 3 with the fixed tube 22, so that the tail gas passes through the front placement box 3 for purification and then is discharged from the housing 2 through the fixed tube 22 and passes through the next placement box 3.
