Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment devices, and more specifically to an activated carbon waste gas adsorption box. Background Art

[0002] The activated carbon waste gas adsorption box is a highly efficient waste gas treatment equipment, mainly used to remove organic solvents and pollutants in low-concentration, large-volume waste gas. The activated carbon waste gas adsorption box utilizes the unbalanced and unsaturated molecular gravity or chemical bond force on the surface of the activated carbon. When the waste gas enters the adsorption box with negative pressure powered by the fan, it contacts the surface of the activated carbon, and the gas molecules are attracted and concentrated on the surface of the activated carbon. The pollutants in the waste gas are adsorbed on the surface of the activated carbon and separated from the gas mixture, thereby achieving purification.

[0003] When the existing activated carbon exhaust gas adsorption box is in use, some solid particle impurities are likely to exist in the exhaust gas. As the exhaust gas contacts the activated carbon, these solid particle impurities will be adsorbed on the surface of the activated carbon. The solid particle impurities will block the micropores of the activated carbon and reduce its specific surface area. Once blocked, the adsorption performance of the activated carbon will be greatly reduced, and the adsorption efficiency of the activated carbon will be significantly reduced. Utility Model Content

[0023] Figure 1 to Figure 5 It is the best embodiment of the utility model, and the following Figure 1 ~Attached Figure 5 The utility model is further described.

[0024] An activated carbon waste gas adsorption box comprises an adsorption box body 1, wherein an air inlet 2 and an exhaust port 3 are respectively arranged at both ends of the adsorption box body 1, two rectangular holes 4 are opened on one side of the adsorption box body 1, the two rectangular holes 4 are connected to the inside of the adsorption box body 1, and the two rectangular holes 4 are arranged in an up-and-down arrangement, a filter component 5 for filtering waste gas is arranged near the air inlet 2 in the adsorption box body 1, a cleaning component 6 for cleaning the filter component 5 is arranged in the adsorption box body 1, and the cleaning component 6 is located between the air inlet 2 and the filter component 5, and two groups of purification components 7 are arranged in the adsorption box body 1.

[0025] The filter assembly 5 includes two fixed plates 501 and a filter screen 502. The top of one of the two fixed plates 501 is fixedly connected to the top of the adsorption box body 1, and the bottom of the other fixed plate 501 is fixedly connected to the bottom of the adsorption box body 1. Both sides of the two fixed plates 501 are fixedly connected to both sides of the adsorption box body 1, and the filter screen 502 is fixedly installed between the two fixed plates 501.

[0026] A baffle 701 is provided in the adsorption box body 1. The baffle 701 is arranged close to the exhaust port 3. The two sides of the baffle 701 are respectively fixedly connected to the two sides of the adsorption box body 1. The top and bottom of the baffle 701 are respectively spaced apart from the top and bottom of the adsorption box body 1. The purification component 7 includes a storage box 702 and a plurality of holes 703. The storage box 702 is a hollow rectangular structure with an open top. Activated carbon can be filled in the storage box 702. A plurality of holes 703 are provided at the bottom of the storage box 702. The two ends of the two storage boxes 702 are respectively slidably connected to the baffle 701 and the corresponding fixed plate 501. The two storage boxes 702 correspond to the two rectangular holes 4 respectively. One side wall of the storage box 702 passes through the rectangular hole 4 and can seal the rectangular hole 4. The two groups of purification components 7 can be taken out from the adsorption box body 1 through the rectangular hole 4.

[0027] In the present embodiment, when in use, the air inlet 2 is externally connected to a pipe for conveying by a fan, and the exhaust gas is conveyed to the external pipe by the fan, and the exhaust gas is conveyed from the air inlet 2 to the adsorption box body 1 through the external pipe. In the initial state, both groups of purification components 7 have a number of honeycomb activated carbons. When the exhaust gas enters the adsorption box body 1 and contacts the filter component 5, the solid particle impurities in the exhaust gas are filtered by the filter component 5, so that the exhaust gas with the solid particle impurities filtered out enters the purification component 7 area, and the harmful gas and odor in the exhaust gas are adsorbed by the honeycomb activated carbons in the purification component 7, and the exhaust gas with harmful gas and odor removed is discharged from the exhaust port 3. When the work is completed, the solid particle impurities adsorbed on the filter component 5 are cleaned by the cleaning component 6, and the two groups of purification components 7 are manually taken out from the adsorption box body 1, and the honeycomb activated carbon in the purification component 7 is replaced, thereby ensuring the efficiency of exhaust gas purification.

[0028] When the exhaust gas enters the adsorption box body 1, the exhaust gas can only pass through the filter screen 502 because of the obstruction of the two fixed plates 501. The solid particle impurities in the exhaust gas will be filtered through the filter screen 502, so that the solid particle impurities are adsorbed on the filter screen 502.

[0029] In the initial state, the staff evenly places a number of honeycomb activated carbons in two storage boxes 702, so that the two storage boxes 702 are filled with honeycomb activated carbons. When the exhaust gas passes through the filter 502 and enters the purification area, the exhaust gas is located between the two groups of purification components 7, and the exhaust gas is blocked by the baffle 701. When the exhaust gas passes through the purification component 7 above, the exhaust gas first passes through a number of holes 703, and then passes through a number of honeycomb activated carbons to absorb harmful gases and odors in the exhaust gas. The exhaust gas with harmful gases and odors removed flows from the gap between the honeycomb activated carbon and the top of the adsorption box body 1 to the exhaust port 3. When the exhaust gas passes through the purification component 7 below, the exhaust gas first contacts the honeycomb activated carbon, and the harmful gases and odors in the exhaust gas are absorbed by the honeycomb activated carbon. The exhaust gas with harmful gases and odors removed passes through the below. Several holes 703 are opened at the bottom of the storage box 702. At this time, the exhaust gas is located in the gap between the lower storage box 702 and the bottom of the adsorption box body 1, and flows to the exhaust port 3, and the exhaust gas with harmful gases and odors removed is discharged through the exhaust port 3. When the work is completed and the honeycomb activated carbon in the storage box 702 needs to be replaced, the storage box 702 is manually taken out from the adsorption box body 1. When taking it out, the storage box 702 slides along the fixed plate 501 and the baffle 701 and is taken out from the rectangular hole 4. At this time, the staff replaces the honeycomb activated carbon in the storage box 702. After the replacement is completed, the staff puts the storage box 702 into the adsorption box body 1 and it is in the initial state. The storage box 702 is close to the inner wall of the adsorption box body 1, and no exhaust gas will flow between the storage box 702 and the inner wall of the adsorption box body 1.

[0030] The cleaning assembly 6 includes a limiting rod 601, a slider 602, a support rod 603, a collection box 604, a collection port 605 and a plurality of brushes 606. The two ends of the limiting rod 601 are respectively fixedly connected to the two sides of the adsorption box body 1, the limiting rod 601 is located above the filter 502, the slider 602 is slidably mounted on the limiting rod 601, and the plurality of brushes 606 are respectively fixedly installed on one side of the slider 602. The plurality of brushes 606 are fitted with the filter 502. One end of the support rod 603 is fixedly connected to the slider 602, and the other end passes through one side of the adsorption box body 1 and slides with the adsorption box body 1. The collection port 605 is opened on one side of the adsorption box body 1 and is located below the slider 602. The collection box 604 is set directly below the slider 602 and slides with the bottom of the adsorption box body 1 and one side of the fixed plate 501 fixed to the bottom of the adsorption box body 1. The top of the collection box 604 is opened, and one side of the collection box 604 passes through the collection port 605. The collection port 605 can be sealed by the side of the collection box 604 passing through the collection port 605.

[0031] In the above structure, when the work is finished, the solid particle impurities adsorbed on the filter screen 502 need to be cleaned. At this time, the staff pulls the support rod 603, and the support rod 603 drives the slider 602 to move. The slider 602 drives a number of brushes 606 to move synchronously along the limit rod 601. The staff pushes and pulls the support rod 603 back and forth, so that the moving brush 606 cleans the solid particle impurities adsorbed on the filter screen 502, so that the solid particle impurities adsorbed on the filter screen 502 are moved back and forth by the brush 606, so that the solid particle impurities gradually fall into the collection box 604 below. At this time, the staff restores the support rod 603 to the initial state. At this time, the staff pulls the collection box 604 to make the collection box 604 come out of the collection port 605, and manually cleans the solid particle impurities in the collection box 604. When the cleaning is completed, the collection box 604 is placed into the adsorption box body 1 from the collection port 605, which is convenient for the staff to clean the solid particle impurities on the filter screen 502.

[0032] The support rod 603 passes through one end of the adsorption box body 1 and is fixedly provided with a handle 10. The handle 10 makes it more convenient to push and pull the support rod 603.

[0033] The collecting box 604 is connected to the adsorption box body 1 through one side of the collecting port 605 by bolts. When the solid particle impurities in the collecting box 604 need to be cleaned, the staff unfastens the bolt connection between the collecting box 604 and the adsorption box body 1. When the solid particle impurities in the collecting box 604 are cleaned, the collecting box 604 is located in the adsorption box body 1 and is in the initial state. At this time, the collecting box 604 is manually connected to the adsorption box body 1 by bolts.

[0034] A fixing rod 8 is arranged directly above the two rectangular holes 4, and one end of the two fixing rods 8 is fixedly connected to the surface of one side of the adsorption box body 1. A limit block 9 is sleeved on the two fixing rods 8, and the limit block 9 is rotatably connected to the corresponding fixing rod 8. The limit block 9 is slidably matched with the corresponding storage box 702 passing through one side of the rectangular hole 4.

[0035] In the above structure, when the storage box 702 needs to be taken out to replace the honeycomb activated carbon, the staff first rotates the limit block 9, and the limit block 9 rotates along the fixed rod 8 so that the limit block 9 no longer blocks the storage box 702. The staff then takes out the storage box 702, and when the honeycomb activated carbon is replaced, the storage box 702 is placed into the adsorption box body 1 and is in the initial state. The staff rotates the limit block 9 so that one side of the limit block 9 is abutted against the side of the storage box 702 passing through the rectangular hole 4. The storage box 702 is abutted against the limit block 9 to prevent the storage box 702 from coming out of the rectangular hole 4 during work.
