Description

Technical Field

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

[0002] Cleaning rooms are designed to meet the cleaning process needs of lean production and maintenance in industrial enterprises. They have multiple functions, including cleaning, water circulation, demisting, and waste gas treatment. Cleaning rooms are typically equipped with dedicated activated carbon waste gas treatment devices. Industrial production processes generate large amounts of waste gas. If this waste gas is released into the air without treatment, it will seriously impact the environment and harm human health. To reduce harmful substances in the waste gas, it needs to be purified before emission. Waste gas treatment methods include adsorption, high-temperature incineration, catalytic combustion, photocatalytic oxidation, plasma treatment, and condensation. Among these, adsorption, specifically activated carbon adsorption, works by utilizing the porous structure of granular activated carbon or activated carbon fibers to capture VOCs (volatile organic compounds) in the waste gas. The VOC-containing organic waste gas is passed through an activated carbon bed, where the VOCs are adsorbed by the adsorbent, purifying the waste gas before it is released into the atmosphere.

[0003] After a period of use, the activated carbon adsorption plates inside the existing activated carbon waste gas treatment device for cleaning rooms will adsorb a large amount of adsorbent substances. Long-term adsorption will cause the activated carbon adsorption capacity to become saturated, resulting in the activated carbon adsorption plates losing their working capacity. Therefore, it is necessary to replace the activated carbon adsorption plates inside the activated carbon adsorption device. However, the existing activated carbon adsorption plates are inconvenient to replace, wasting a lot of time for users and reducing the practicality of the activated carbon adsorption device.

[0004] Therefore, this utility model provides a special activated carbon waste gas treatment device for cleaning rooms to solve the above problems. Utility Model Content

[0017] (III) Beneficial Effects

[0018] 1.

Then, the negative pressure fan, heating wire, air pump and drive motor are started to heat the outside air into hot steam. The hot steam comes into contact with the activated carbon plate, causing the pollutants adsorbed on the activated carbon to desorb and blow into the inside of the sealing frame. The pollutants in the sealing frame are input to the external condensation and recovery device through the air supply pipe for recycling. After treatment, the activated carbon plate recovers most of its adsorption capacity. It does not need to be disassembled many times or replaced frequently, which reduces the workload of the staff.

[0019] 2. With the arrangement of the sealing plate, the second electric push rod, the push plate, the sliding frame, and the third electric push rod, when the activated carbon plate cannot be used, the second electric push rod is activated to drive the sealing plate to slide, causing the sealing plate to detach from one side of the rectangular groove. Then, the third electric push rod is activated to drive the sliding frame to move. The sliding component drives the push plate at one end to slide the activated carbon plate outward a certain distance, making it easier for the staff to remove the activated carbon plate and replace it. This reduces the replacement time for the staff and improves the practicality of the device. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides a special activated carbon waste gas treatment device for cleaning rooms, including a treatment box 1. Several mounting rails 2 are provided on the upper and lower sides of the treatment box 1. Activated carbon plates 3 are slidably installed inside the mounting rails 2 on the upper and lower sides. A desorption component 4 is provided on the lower surface of the treatment box 1.

[0029] The desorption assembly 4 includes several first air holes 401 on the upper and lower sides of the processing box 1. First sliding grooves are provided on both the upper and lower sides of the processing box 1. A sliding plate 402 is slidably connected inside the first sliding groove. Several second air holes 403 are provided on the surface of the sliding plate 402. A fixed frame 404 is fixedly installed on the lower surface of the processing box 1. A reciprocating screw 405 is rotatably connected inside the fixed frame 404. A sliding member is threaded onto the outer surface of the reciprocating screw 405. A first air supply pipe 406 is fixedly installed on the top of the sliding member. Several nozzles are provided on the surface of the first air supply pipe 406. A corrugated hose is fixedly installed at one end of the first air supply pipe 406. An air pump is fixedly installed at one end of the corrugated hose. An air inlet frame is fixedly installed at one end of the air pump through a pipe. The air inlet frame is fixedly installed on the fixed frame. The side surface of frame 404 and the side surface of the air intake frame are provided with several negative pressure fans 407. The inside of the air intake frame is provided with heating resistance wire 408. The side surface of the fixed frame 404 is provided with a drive motor. The output end of the drive motor is fixedly installed with a reciprocating lead screw 405. The upper surface of the processing box 1 is fixedly installed with a sealing frame. The upper surface of the sealing frame is provided with an air supply pipe. One end of the first air supply pipe 406 is fixedly installed with a guide block. The inner side wall of the fixed frame 404 is provided with a guide groove. The guide block is slidably connected to the inside of the guide groove. One side of the two sliding plates 402 is fixedly installed with a pull rod 409. One end of the pull rod 409 is fixedly installed with a connecting ring. One side of the connecting ring is fixedly installed with a first electric push rod 410. The first electric push rod 410 is fixedly installed on the side surface of the processing box 1.

[0030] When the activated carbon plate 3 is saturated, the operator activates the first electric push rod 410 to move the connecting ring. The connecting ring moves the pull rods 409 on both sides, which in turn move the sliding plate 402 inside the first sliding groove. This causes the second air hole 403 on the surface of the sliding plate 402 to coincide with the first air hole 401. Then, the negative pressure fan 407 is activated to draw outside air into the air intake frame. The air is heated by the heating wire 408, and then the hot air is drawn into the corrugated hose by the air pump and then into the first air supply pipe 406. Hot steam is sprayed out through the nozzles on the surface. The hot steam comes into contact with the saturated activated carbon plate 3, causing the pollutants adsorbed on the activated carbon plate 3 to desorb. The pollutants are then blown into the interior of the sealing frame by the air force. The air supply pipe on the surface of the sealing frame is connected to the external condensation recovery device for recycling and reuse, reducing operating costs and environmental pollution. After treatment, the activated carbon plate 3 recovers most of its adsorption capacity, eliminating the need for multiple disassemblies and frequent replacements, thus reducing the workload of the operators.

[0031] Several rectangular grooves are formed on one side surface of the treatment box 1, which are adapted to the activated carbon plate 3. A second sliding groove is formed on the side surface of the rectangular groove, and a sealing plate 5 is slidably connected inside the second sliding groove. A third sliding groove is formed on the upper surface of the second sliding groove. A fixing rod is fixedly installed on the upper surface of the sealing plate 5. A horizontal plate is fixedly installed on the top of several fixing rods. A second electric push rod 6 is provided on the side surface of the horizontal plate. The second electric push rod 6 is fixedly installed on the upper surface of the treatment box 1. A push plate 7 overlaps on the side surface of the activated carbon plate 3. The push plate 7 is slidably connected to the side surface of the treatment box 1. A sliding frame 8 is fixedly installed on one side of several push plates 7. The sliding frame 8 is slidably connected through the side surface of the treatment box 1. A third electric push rod 9 is fixedly installed on the side surface of the sliding frame 8. The third electric push rod 9 is fixedly installed on the side surface of the treatment box 1.

[0032] When activated carbon plate 3 becomes unusable, the operator activates the second electric push rod 6 to move the horizontal plate. The horizontal plate moves the fixing rod on the lower surface, which in turn moves the sealing plate 5 inside the second groove, causing the sealing plate 5 to detach from one side of the rectangular groove. Then, the operator activates the third electric push rod 9 to move the sliding frame 8. The sliding frame 8 moves the push plate 7 on one side, causing the activated carbon plate 3 to slide outward. The activated carbon plate 3 passes through the rectangular groove, facilitating disassembly and replacement by the operator, reducing replacement time, and improving the practicality of the device.

[0033] An air inlet slot is provided on the upper surface of the treatment box 1, and an air inlet frame is provided on the surface of the air inlet slot. An exhaust pipe is provided on one side surface of the treatment box 1, and a flow guide fan 10 is provided on the other side surface of the treatment box 1. A flow guide hole is provided on the other side surface of the treatment box 1, and a dustproof net 11 is provided on one side of the flow guide hole. The dustproof net 11 is installed on the side surface of the treatment box 1 by bolts.

[0034] The staff inputs the exhaust gas into the air intake trough, and then starts the guide fan 10 to input the outside air into the treatment box 1. The outside air is filtered by the dust filter 11 to reduce the burden on the activated carbon plate 3, which will drive the exhaust gas through the activated carbon plate 3, thus improving the filtration efficiency of the device.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
