Description

Technical Field

[0001] This utility model relates to the field of flue gas treatment technology, specifically to a carbon monoxide catalytic oxidation treatment device. Background Technology

[0002] Flue gas treatment refers to the technical process of purifying and treating waste gas generated during industrial production or combustion. It aims to remove harmful substances, reduce environmental pollution, and meet emission standards. Carbon monoxide is a harmful gas, and it needs to be rendered harmless using specialized equipment when it is emitted. This mainly involves converting toxic carbon monoxide into harmless carbon dioxide through a catalytic reaction.

[0003] The current treatment equipment still has some shortcomings, such as the poor effect of the flue gas treatment system in purifying and removing carbon monoxide.

[0004] To overcome the problem of poor carbon monoxide treatment effect, the prior art (publication number: CN216654086U) Chinese patent discloses a carbon monoxide purification and removal device. The bottom of the heating chamber is sealed with a fresh air valve for supplying air. A heating device extending into the interior is installed on the other side of the heating chamber. The upper end of the heating chamber is sealed with a catalytic chamber connected to it. The upper end of the catalytic chamber is connected with an exhaust pipe connected to it. Multiple catalytic boxes that are evenly distributed and adapted to it are detachably installed inside the catalytic chamber. The catalytic boxes are provided with multiple evenly distributed vent holes, and the gas below the catalytic box can flow to the top of the catalytic box through the vent holes. The catalytic box is filled with a carbon monoxide catalyst.

[0005] However, the current treatment equipment still has certain shortcomings. The treatment equipment mentioned above can achieve the purpose of efficiently purifying and removing carbon monoxide by increasing the contact area and contact time between carbon monoxide and carbon monoxide catalyst. However, the catalyst needs to be replaced regularly, but replacing multiple catalysts is troublesome and time-consuming, which affects the efficiency of the equipment. Therefore, the existing structure needs to be improved. Utility Model Content

[0006] The purpose of this invention is to provide a carbon monoxide catalytic oxidation treatment device to solve the problem mentioned in the background art that it is inconvenient to replace the catalyst in the catalytic oxidation treatment device.

[0008] The processing chamber has two movable slots on its side, and each movable slot has a guide slot symmetrically provided on its side. A sealing plate is movably connected inside the movable slot. A sealing ring is connected to the inner side of the processing chamber and the movable slot. The placement frame and the sealing plate are respectively sealed to the inner cavity of the processing chamber and the inner side of the movable slot through the sealing ring.

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.

[0033] Example 1, such as Figures 1-8 The present invention provides the following technical solution to address the problem of inconvenient catalyst replacement in catalytic oxidation treatment equipment: A rotating mechanism is disclosed, comprising a heating box 1, a treatment chamber 2 connected to the top of the heating box 1, a flue gas inlet 3 installed on one side of the heating box 1, and a heating device 4 connected to the other side of the heating box 1. A placement frame 5 is connected inside the treatment chamber 2. Two movable slots 201 are opened on the side of the treatment chamber 2, and each movable slot 201 has a guide slot 202 symmetrically opened on its side. A sealing plate 203 is movably connected inside the movable slot 201. Sealing rings are connected to the inner sides of the treatment chamber 2 and the movable slots 201. The placement frame 5 and the sealing plate 203 are respectively sealed to the inner cavity of the treatment chamber 2 and the inner side of the movable slots 201 through the sealing rings. A rotating mechanism for improving the operating efficiency of the oxidation treatment equipment is provided inside the treatment chamber 2. The rotating mechanism includes a motor 204, which is installed in the treatment chamber 2 near the guide slot 2. Inside the groove 202, a fixing rod 205 is fixed to the output end of the motor 204. A small gear 206 is fixed to the end of the fixing rod 205 away from the motor 204. A large gear 207 is meshed with the side of the small gear 206. The large gear 207 rotates inside the processing chamber 2. A placement frame 5 is fixed between the large gears 207. The placement frame 5 is rotatably connected to the inside of the processing chamber 2 through the large gear 207. Guide blocks 208 are fixed to both sides of the sealing plate 203. The guide blocks 208 slide inside the guide groove 202. Tooth blocks 209 are symmetrically fixed to the side of the sealing plate 203 near the placement frame 5. The tooth blocks 209 are meshed with the side of the small gear 206. A rotating block 210 is also fixed to the surface of the fixing rod 205. A transmission belt 211 is connected to the surface of the rotating block 210. A rotating block 212 is connected to the inner side of the transmission belt 211 away from the rotating block 210. The rotating block 212 is fixed to the surface of another fixing rod 205.

[0034] During operation, carbon monoxide is fed into the heating chamber 1 through the flue gas inlet 3. Inside the heating chamber 1, the carbon monoxide is heated to a specified temperature by the heating device 4. The heated carbon monoxide is then heated to a temperature more suitable for catalytic oxidation. After heating, the carbon monoxide is fed into the treatment chamber 2. During its transport within the treatment chamber 2, it passes through the catalyst inside the two placement frames 5. Upon contact with the catalyst, the carbon monoxide reacts, producing harmless gas which is then discharged through the treatment chamber 2. The catalyst inside the placement frames 5 needs to be replaced periodically. The motor 20 can be started. 4. The fixed rod 205 rotates, which in turn drives the pinion 206 to rotate. The pinion 206 then drives the large gear 207 to mesh with the gear block 209. The large gear 207 and the gear block 209 move in opposite directions. When the large gear 207 meshes and rotates, it can rotate the processing chamber 2, and it can also drive the placement frame 5 to rotate. The placement frame 5 will rotate towards the movable slot 201. Simultaneously, the gear block 209 can drive the sealing plate 203 to move. The movement of the sealing plate 203 can also drive... When the guide block 208 moves, the sealing plate 203 can move inside the movable groove 201. Both the guide block 208 and the toothed block 209 can slide through the guide groove 202. When the placement frame 5 rotates to the inside of the movable groove 201, the sealing plate 203 can slide down to the bottom of the movable groove 201. Furthermore, when the fixed rod 205 rotates, it can drive the rotating block 210 to rotate. The rotating block 210, through the transmission belt 211, can drive the rotating block 212 to rotate. The rotating block 212, in turn, drives another set of fixed rods 205 to rotate. 5 can rotate inside the processing chamber 2. Another set of fixed rods 205 can drive another placement frame 5 to rotate to the inside of the movable slot 201. At this time, the catalyst inside the placement frame 5 will be exposed, and the operator can quickly replace the catalyst. When the processing equipment is running, the placement frame 5 will press against the side of the sealing ring inside the cavity of the processing chamber 2, which can prevent gas from leaking from other directions of the placement frame 5. At the same time that the placement frame 5 is pressed against the cavity of the processing chamber 2, the sealing plate 203 will seal the opening of the movable slot 201 through another sealing ring to prevent gas leakage.

[0035] Example 2, as follows Figure 3 , Figure 4 , Figure 9 and Figure 10The present invention provides the following technical solution to address the problem of unstable catalyst placement: In addition to the first embodiment, a compression mechanism is disclosed: a pressing plate 501 is rotatably connected inside the placement frame 5. Two sets of pressing plates 501 are rotatably connected inside the placement frame 5 via torsion springs. A compression mechanism for fixing the catalyst is provided inside the placement frame 5. The compression mechanism includes a rubber block 502, which is fixed inside the placement frame 5 away from the pressing plate 501. The rubber block 502 and the pressing plate 501 form a snap-fit ​​connection. The pressing plate 501 is rotatably connected inside the placement frame 5 via torsion springs.

[0036] After the catalyst is replaced, a new one needs to be placed inside the placement frame 5. At this time, the catalyst will be located on the side of the pressing plate 501. The pressing plate 501 can be rotated through the placement frame 5. When the pressing plate 501 rotates, it can tighten the torsion spring. When the pressing plate 501 rotates to the inclined surface of the rubber block 502, it can be squeezed. After the rubber block 502 is squeezed, it can deform through the rubber material. When the rubber block 502 deforms, the pressing plate 501 can rotate to the plane of the rubber block 502 for locking and positioning. The positioned pressing plate 501 will also press on the surface of the catalyst pack, thereby achieving stable fixation of the catalyst.
