Description

Technical Field

[0001] The present invention relates to the technical field of tail gas treatment, and in particular to a high-concentration organic gas tail gas catalytic oxidation device and an operating method. Background Art

[0002] The chemical industry produces a large amount of exhaust gas during the production process. If the exhaust gas is discharged without treatment, it will contain a certain amount of chemical substances, which will not only cause economic waste, but some chemical substances will seriously damage the surrounding ecological environment and cause environmental pollution. Therefore, it is very necessary to reasonably and effectively treat the exhaust gas from the chemical industry. For this reason, it is necessary to install a catalytic oxidation reaction device at the tail end of the exhaust gas emission.

[0003] Referring to the Chinese utility model patent, the publication number is: CN 220715432 U, and the name is: A high-concentration organic gas exhaust catalytic oxidation reaction device. This invention patent drives the rotation of the rotating shaft and the first fan through the output end of the motor, and then drives the gear ring to rotate through the rotating shaft. The gear ring drives the two gears to rotate and then drives the fixed shaft and the fixed plate to rotate, so that the straight rod and the rotating blade can rotate together, which solves the problem that most of the existing exhaust catalytic oxidation reaction devices may not be able to fully fuse and react with the solvent.

[0004] However, in actual use, the above and similar technical solutions still have some problems: 1. When the oxidation plate is configured with a single layer, the area close to the gas inlet is easy to reach the adsorption saturation state, while the area far from the inlet may not be fully utilized, resulting in low overall treatment efficiency. This phenomenon not only limits the effective range of exhaust gas treatment, but also causes the wind resistance to increase immediately. If the unsaturated oxidation plate is replaced immediately, it will cause unnecessary resource consumption and economic losses; 2. When dealing with high-concentration waste gas, the filtering capacity of a single oxidation plate is insufficient and it is difficult to achieve deep purification. If multiple oxidation plates are added to enhance the processing capacity, it is easy to cause the problem of uneven waste gas distribution. In particular, when the processing load of one of the oxidation plates exceeds the design range, the oxidation reaction may not be able to proceed thoroughly, affecting the purification effect. 3. The currently used oxidation plates lack intuitive saturation monitoring methods, and it is impossible to immediately determine whether they need to be replaced. In addition, the replacement of the oxidation plates usually requires downtime, which not only interrupts the continuous workflow, but also significantly reduces the overall work efficiency, causing adverse effects on production operations.

Exhaust gas enters the air intake tank and is oxidized and catalyzed by the oxidation plate. The toothed belt drives the oxidation plate to move in the air intake tank toward the air intake pipe, so that the unsaturated oxidation plate at the rear gradually approaches the air intake pipe, so that each oxidation plate is evenly exposed to the exhaust gas. S3. When the oxidation plate is saturated, its resistance will become larger. As the exhaust gas continues to enter, it will push the oxidation plate to move, the oxidation plate will slide, the pin block will be separated from the pin groove, the oxidation plate will move to the transparent ring, and the cover plate will be opened to expose the convergence groove. The movement of the oxidation plate can be observed through the transparent ring, and the saturated oxidation plate can be identified.

[0016] Compared with the prior art, the present invention provides a high-concentration organic gas tail gas catalytic oxidation device, which has the following beneficial effects: 1. Exhaust gas enters the air intake pipe and enters the interior of the flow control slot. The second motor is started. When the second motor is working, it drives the push block to rotate. The push block pushes the end rings one by one, the telescopic tube is compressed, the fourth spring is compressed, and the exhaust gas inside the fixed cylinder is pressed into the interior of each air intake slot in one direction through the second one-way valve. When the push block is disengaged, the fourth spring is reset, thereby pushing the telescopic tube to extend, and the exhaust gas inside the flow control slot will be unidirectionally sucked into the fixed cylinder through the first one-way valve, thereby reciprocatingly discharging the exhaust gas into the interior of each air intake slot. Through the continuous rotation of the push block, the high-concentration exhaust gas is continuously distributed to the interior of each air intake slot, thereby ensuring the uniformity of high-concentration exhaust gas treatment and avoiding the exhaust gas in a single air intake slot being relatively concentrated.

[0017] 2. Exhaust gas enters the interior of the air intake slot and is oxidized and catalyzed by the oxidation plate to remove harmful substances. Multiple oxidation plates are arranged inside each air intake slot to ensure the safety of the exhaust gas through layer-by-layer oxidation. Since the exhaust gas concentration in contact with the oxidation plate close to one end of the intake pipe is relatively high, it is easy to be saturated in advance. The first motor is started to drive the second gear to rotate, which drives one of the first gears to rotate, thereby driving the toothed belt to move. The toothed belt drives the oxidation plate to move inside the air intake slot toward the intake pipe, so that the unsaturated oxidation plate at the rear gradually approaches the intake pipe, thereby ensuring the uniformity of all oxidation plates contacting the exhaust gas.

[0018] 3. When the oxidation plate is saturated, its resistance will become larger. With the continuous entry of exhaust gas, the oxidation plate will be pushed to move, the oxidation plate will slide, the pin block will be separated from the pin groove, and the oxidation plate will move to the transparent ring. The cover plate will be opened to expose the convergence groove. The movement of the oxidation plate can be observed through the transparent ring. The edge of the oxidation plate can be graffitied with a color ring for easy identification. The status of the oxidation plate is convenient for timely replacement. Press the buckle rod to pull the end block out of the plug block and push the oxidation plate in the reverse direction for easy replacement. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Example 3: Based on Example 2 Figure 5 , Figure 6 and Figure 7 , a flow control mechanism 8 is connected to the pipe body 1, and the flow control mechanism 8 includes a flow control groove 81. The pipe body 1 is provided with a flow control groove 81 at one end of the intake pipe 2, and a plurality of fixed cylinders 82 corresponding to the intake grooves 64 are installed on the side wall of the pipe body 1 located at the flow control groove 81, and an end ring 84 is provided on the side of the fixed cylinder 82 close to the inside of the flow control groove 81, and a telescopic tube 83 is installed between the end ring 84 and the fixed cylinder 82, a first one-way valve 85 is installed on the end ring 84, a second one-way valve 89 is installed on the fixed cylinder 82, and a fourth spring 88 is installed between the end ring 84 and the fixed cylinder 82.

[0031] In the present invention, the tube body 1 is in a fan-shaped column, and the convergence groove 65 is arranged at the axis center of the fan-shaped column. The cover plate 4 is rotatably connected to the tube body 1, and the convergence groove 65 is connected to the outside through the cover plate 4, so that the oxidation plates 61 inside each air inlet groove 64 are conveniently gathered into the convergence groove 65, which is convenient for later replacement.

[0032] In the present invention, the push block 87 is in a scimitar-shaped structure, and the width of the push block 87 is smaller than the diameter of the end ring 84, so that it is convenient to push one end ring 84 to move each time, thereby making it convenient for the exhaust gas to evenly enter each air inlet groove 64.

[0033] Working principle: the air inlet pipe 2 is used to connect the high-concentration organic tail gas, and the exhaust pipe 5 is used to connect the negative pressure exhaust fan. When the exhaust gas is treated, under the negative pressure at the end of the exhaust pipe 5, the exhaust gas enters the air inlet pipe 2 and enters the interior of the flow control slot 81, and the second motor 86 is started. When the second motor 86 works, it drives the push block 87 to rotate, and the push block 87 pushes the end ring 84 one by one, and the telescopic tube 83 is compressed. The fourth spring 88 is compressed, and the exhaust gas inside the fixed cylinder 82 is pressed into the interior of each air inlet slot 64 in one direction through the second one-way valve 89. When the push block 87 is disengaged, the fourth spring 88 is reset, thereby pushing the telescopic tube 83 to extend, and the exhaust gas inside the flow control slot 81 will be unidirectionally sucked into the fixed cylinder 82 through the first one-way valve 85, thereby reciprocating and discharging the exhaust gas into the interior of each air inlet slot 64. Through the continuous rotation of the push block 87, the high-concentration exhaust gas is continuously distributed to the interior of each air inlet slot 64, thereby ensuring the uniformity of the treatment of high-concentration exhaust gas and avoiding the concentration of exhaust gas inside a single air inlet slot 64. The exhaust gas enters the interior of the air intake slot 64 and is oxidized and catalyzed by the oxidation plate 61, thereby removing harmful substances. A plurality of oxidation plates 61 are arranged inside each air intake slot 64, and the exhaust gas safety is ensured by layer-by-layer oxidation. Since the exhaust gas concentration of the oxidation plate 61 near one end of the air intake pipe 2 is higher, it is easy to be saturated in advance, and the first motor 673 is started to drive the second gear 672 to rotate, driving one of the first gears 671 to rotate, thereby driving the toothed belt 62 to move, and the toothed belt 62 drives the oxidation plate 61 to move in the air intake slot 64 toward the air intake pipe 2, so that the unsaturated oxidation plate 61 at the rear gradually Close to the intake pipe 2, so as to ensure that all oxidation plates 61 are in contact with the exhaust gas uniformly, the front fixed frame 63 contacts with the truss 66, and under the push of the toothed belt 62, the fixed frame 63 rotates around the slide bar 74, and the side wall of the fixed frame 63 contacts with the end block 71, thereby pulling the slide bar 74 to rotate outward, and the third spring 76 is stretched, so as to realize the flipping of the fixed frame 63, so as to facilitate the fixed frame 63 to pass through the through slot 68. When the fixed frame 63 is separated from the truss 66, the third spring 76 contracts, and the fixed frame 63 is pulled back to its original position through the slide bar 74, and the oxidation plate 61 enters the convergence slot 65, and then enters from the tail of the intake slot 64, thereby circulating; When the oxidation plate 61 is saturated, its resistance will become larger. With the continuous entry of exhaust gas, the oxidation plate 61 is pushed to move, the oxidation plate 61 slides, the pin block 691 is disengaged from the pin groove 694, and the oxidation plate 61 moves to the transparent ring 693. The cover plate 4 is opened to expose the convergence groove 65. The movement of the oxidation plate 61 can be observed through the transparent ring 693. The edge of the oxidation plate 61 can be graffitied with a color ring to facilitate identification. The status of the oxidation plate 61 is convenient for timely replacement. The buckle rod 72 is pressed, the second spring 75 is compressed, and the buckle rod 72 is disengaged from the buckle groove 77, so that the end block 71 is easily pulled out from the plug block 73. After the fixed frame 63 is taken out, the oxidation plate 61 is pushed in the reverse direction to facilitate replacement. The storage box 31 is provided with a slot 32 to facilitate the placement and storage of the oxidation plate 61.
