Description

Technical Field

[0001] This utility model belongs to the field of waste gas treatment technology, specifically relating to a zeolite rotor RTO waste gas treatment device. Background Technology

[0002] With the rapid development of industrialization, air pollution has become increasingly prominent. The large-scale emission of organic waste gas has harmed the atmospheric environment. In order to effectively treat these waste gases, various advanced waste gas treatment technologies have emerged. Among them, the zeolite rotor + RTO waste gas treatment process has gradually become the first choice for enterprises due to its high efficiency and environmental protection characteristics.

[0003] In existing technologies, brushes are typically installed on the surface of zeolite rotors to prevent dust and other contaminants from accumulating on the surface after prolonged use, which could lead to blockage of the rotor's channels. However, as the zeolite rotor operates, the brushes continuously clean its surface, which can cause wear and tear over time, thus affecting the rotor's lifespan.

[0004] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide a zeolite rotor RTO waste gas treatment device.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a zeolite rotor RTO waste gas treatment device, which can solve the problem of wear on the surface of the zeolite rotor caused by long-term operation of brushes in the prior art.

[0007] To achieve the above objectives, a specific embodiment of the present invention provides a zeolite rotor RTO waste gas treatment device, comprising: a zeolite rotor housing and a zeolite rotor mechanism;

[0008] A pre-filter box is connected to one side of the zeolite rotor box. An air inlet is provided on the pre-filter box. An exhaust port is provided on the zeolite rotor box. A desorption zone and a cooling zone are provided inside the zeolite rotor box. An RTO combustion furnace is provided on one side of the zeolite rotor box. A pair of hot air pipes are connected between the RTO combustion furnace and the desorption zone.

[0009] The zeolite wheel mechanism is installed inside a zeolite wheel housing. The zeolite wheel mechanism includes a rotating groove carved into the zeolite wheel housing. A zeolite wheel is rotatably mounted inside the rotating groove. A drive shaft is fixed to the zeolite wheel. A bearing seat is fixed to the bottom wall of the zeolite wheel housing. A rotating base is rotatably mounted on the bearing seat. A gear is fixed to the rotating base. A fixed seat is fixed to the gear. A rotating head is positioned above the fixed seat. A fixed rod is fixed between the fixed seat and the rotating head. A cleaning brush is installed between the fixed seat and the rotating head. A support rod is fixed inside the zeolite wheel housing. The rotating head rotates on the support rod. An actuating block adapted to the gear tooth groove is fixed to the zeolite wheel.

[0010] In one or more embodiments of this utility model, a plurality of filter screens are installed in the air inlet. The filter screens are replaceable, and the multi-layer filter screens are set to pre-filter the exhaust gas entering the zeolite rotor box, filtering out particulate matter in the exhaust gas.

[0011] In one or more embodiments of this utility model, an exhaust fan is installed on the zeolite rotor housing, and a connecting pipe is connected between the exhaust fan and the cooling zone. A cold air inlet pipe is connected to the cooling zone. The exhaust fan drives the flow of gas, causing external cold air to flow into the cooling zone through the cold air inlet pipe to cool the zeolite rotor. Then, the cooled gas is transmitted to the exhaust fan through the connecting pipe and discharged from the equipment.

[0012] In one or more embodiments of this utility model, a plurality of pulleys are installed on the inner wall of the rotating groove, and the pulleys are used to assist the zeolite rotor in rotating within the rotating groove.

[0013] In one or more embodiments of this utility model, the cleaning brush rotates between the fixed base and the rotating head. By rotating the cleaning brush, the surface of the zeolite rotor is cleaned.

[0014] In one or more embodiments of this utility model, a first bevel gear is fixed to one end of the cleaning brush that passes through the rotating head, and a second bevel gear is fixed on the transmission shaft. The rotation of the second bevel gear drives the first bevel gear to rotate, and the first bevel gear drives the cleaning brush to rotate, so that the cleaning brush cleans the surface of the zeolite wheel.

[0015] In one or more embodiments of this utility model, the first bevel gear and the second bevel gear mesh with each other. When the gear drives the cleaning brush to rotate and fit against the surface of the zeolite wheel through the fixed seat, the first bevel gear also rotates to mesh with the second bevel gear.

[0016] In one or more embodiments of this utility model, a pair of locking blocks are installed on the shaft seat, and multiple slots adapted to the locking blocks are carved on the rotating base.

[0017] In one or more embodiments of this utility model, a spring is installed between the locking block and the inner wall of the bearing seat, and the spring force is used to push the locking block into the locking slot.

[0018] In one or more embodiments of this utility model, the number of slots is consistent with the number of gear slots, so that when the cleaning brush rotates to fit against the zeolite wheel, the locking block is just locked in the slot, stabilizing the gear and ensuring that the cleaning brush is in the optimal cleaning position, while ensuring that the first bevel gear and the second bevel gear can mesh together.

[0019] Compared with the prior art, this utility model, through its structural design, enables the cleaning brush to clean the zeolite rotor intermittently, avoiding damage to the surface of the zeolite rotor caused by continuous cleaning by the brush, thereby effectively improving the service life of the zeolite rotor.

Detailed Implementation

[0032] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0033] like Figures 1 to 9 As shown, a zeolite rotor RTO waste gas treatment device in one embodiment of the present invention includes: a zeolite rotor housing 1 and a zeolite rotor mechanism 2.

[0034] like Figures 1 to 3As shown, a pre-filter box 101 is connected to one side of the zeolite rotor housing 1. The pre-filter box 101 has an air inlet 104. Exhaust gas enters the pre-filter box 101 through the air inlet 104 for pre-filtration, removing particulate matter. The filtered exhaust gas is then transferred to the zeolite rotor housing 1. An exhaust port 105 is provided on the zeolite rotor housing 1. The gas filtered by the zeolite rotor 202 is discharged through the exhaust port 105. The zeolite rotor housing 1 is provided with a desorption zone 109 and a cooling zone 110. An RTO combustion furnace 102 is provided on one side of the zeolite rotor housing 1. A pair of hot air pipes 108 are connected between the RTO combustion furnace 102 and the desorption zone 109. The RTO combustion furnace 102 transmits hot air to the desorption zone 109 through one hot air pipe 108 to desorb the organic matter adsorbed on the zeolite rotor 202. Then, the air is transmitted to the RTO combustion furnace 102 through the other hot air pipe 108 for further processing. The zeolite rotor 202 is cooled in the cooling zone 110.

[0035] like Figures 1 to 3 As shown, multiple filter screens 111 are installed inside the air inlet 104. The filter screens 111 are replaceable, and the multi-layer filter screens 111 pre-filter the exhaust gas entering the zeolite rotor housing 1, removing particulate matter from the exhaust gas. An exhaust fan body 103 is installed on the zeolite rotor housing 1. A connecting pipe 107 connects the exhaust fan body 103 to the cooling zone 110. A cold air inlet pipe 106 is connected to the cooling zone 110. The exhaust fan body 103 drives the flow of gas, causing external cold air to flow into the cooling zone 110 through the cold air inlet pipe 106 to cool the zeolite rotor 202. Then, the cooled gas is transported to the exhaust fan body 103 through the connecting pipe 107 and discharged from the equipment.

[0036] like Figures 3 to 9 As shown, the zeolite rotor mechanism 2 is installed inside the zeolite rotor housing 1. The zeolite rotor mechanism 2 includes a rotating groove 201, which is carved into the zeolite rotor housing 1. A zeolite rotor 202 is rotatably arranged inside the rotating groove 201. A drive shaft 204 is fixed on the zeolite rotor 202. One end of the drive shaft 204 is located outside the zeolite rotor housing 1 and is used to connect an external drive device to drive it to rotate. The drive shaft 204 drives the zeolite rotor 202 to rotate, and the zeolite rotor 202 adsorbs organic matter in the waste gas. A bearing seat 206 is fixed on the bottom wall of the zeolite rotor housing 1. A rotating base 208 is rotatably arranged on the bearing seat 206. A gear 209 is fixed on the rotating base 208. A fixed seat 210 is fixed on the gear 209. The bearing seat 206 serves as a support and limiter. The gear 209 drives the rotating base 208 and the fixed seat 210 to rotate.

[0037] like Figures 3 to 9As shown, a rotating head 207 is provided above the fixed base 210. A fixed rod 211 is fixed between the fixed base 210 and the rotating head 207. A cleaning brush 212 is installed between the fixed base 210 and the rotating head 207. A support rod 205 is fixed inside the zeolite wheel housing 1. The rotating head 207 rotates on the support rod 205. The rotation of the fixed base 210 drives the fixed rod 211 and the cleaning brush 212 to rotate, so that the cleaning brush 212 rotates to fit against the zeolite wheel 202, or rotates and moves the cleaning brush 212 away from the surface of the zeolite wheel 202. The support rod 205 plays a fixed support role.

[0038] like Figures 3 to 9 As shown, a toggle block 215 is fixed on the zeolite wheel 202, which is adapted to the tooth groove of the gear 209. When the zeolite wheel 202 drives the toggle block 215 to rotate to the gear 209, the toggle block 215 meshes with one tooth groove of the gear 209 and drives the gear 209 to rotate at a certain angle. At the same time, the gear 209 drives the cleaning brush 212 to rotate. When the number of rotations of the toggle block 215 driven by the zeolite wheel 202 is exactly the same as the number of tooth grooves of the gear 209, the toggle block 215 just makes the gear 209 rotate one revolution. This causes the gear 209 to drive the cleaning brush 212 to rotate again until it is in contact with the zeolite wheel 202, so that the cleaning brush 212 cleans the surface of the zeolite wheel 202, thereby realizing the intermittent cleaning of the surface of the zeolite wheel 202 by the cleaning brush 212.

[0039] like Figures 3 to 9 As shown, multiple pulleys 203 are installed on the inner wall of the rotating groove 201. The pulleys 203 assist the zeolite rotor 202 in rotating within the rotating groove 201. A cleaning brush 212 rotates between the fixed base 210 and the rotating head 207. By rotating the cleaning brush 212, it cleans the surface of the zeolite rotor 202. A first bevel gear 213 is fixed to one end of the cleaning brush 212 that passes through the rotating head 207. A second bevel gear 214 is fixed to the drive shaft 204. The rotation of the second bevel gear 214 drives the first bevel gear 213 to rotate, which in turn drives the cleaning brush 212 to rotate, thus cleaning the surface of the zeolite rotor 202. The first bevel gear 213 and the second bevel gear 214 mesh with each other. When the gear 209 drives the cleaning brush 212 to rotate and fit against the surface of the zeolite wheel 202 through the fixed seat 210, the first bevel gear 213 also rotates to mesh with the second bevel gear 214.

[0040] like Figures 3 to 9As shown, a pair of locking blocks 216 are installed on the bearing seat 206, and multiple slots 217 adapted to the locking blocks 216 are carved on the rotating base 208. The locking blocks 216 are engaged in the slots 217, stabilizing the gear 209 so that it cannot rotate when no external force is applied. A spring 218 is installed between the locking blocks 216 and the inner wall of the bearing seat 206. The elastic force of the spring 218 is used to push the locking blocks 216 into the slots 217.

[0041] like Figures 3 to 9 As shown, the number of slots 217 is consistent with the number of tooth slots of gear 209, so that when the cleaning brush 212 rotates to fit against the zeolite wheel 202, the locking block 216 is just locked in the slot 217, stabilizing the gear 209 and ensuring that the cleaning brush 212 is in the optimal cleaning position, while ensuring that the first bevel gear 213 and the second bevel gear 214 can mesh together.

[0042] Working Principle: When using this equipment, firstly, an external drive device is connected to the drive shaft 204 to rotate it. The drive shaft 204 drives the zeolite rotor 202 to rotate. The waste gas to be treated enters the pre-filter box 101 through the inlet 104 for pre-filtering of particulate matter. After filtration, it is transferred to the zeolite rotor box 1, where the zeolite rotor 202 adsorbs organic matter from the waste gas. The filtered gas is discharged through the exhaust port 105. Simultaneously, the RTO combustion furnace 102 delivers hot air through... Hot air is transmitted from one side of the hot air duct 108 to the desorption zone 109. The hot air in the desorption zone 109 desorbs the organic matter adsorbed on the zeolite rotor 202. The desorbed organic matter is then transmitted to the zeolite rotor 202 for processing through the hot air duct 108 on the other side. At the same time, the exhaust fan 103 is started. The exhaust fan 103 drives the gas flow, so that the cold air outside flows into the cooling zone 110 through the cold air inlet duct 106 to cool the zeolite rotor 202, thereby enabling the zeolite rotor 202 to perform organic matter circulation filtration.

[0043] As the air inlet 104 drives the zeolite wheel 202 to rotate, when the zeolite wheel 202 drives the actuating block 215 to rotate to the gear 209, the actuating block 215 meshes with one tooth groove of the gear 209, causing the gear 209 to rotate at a certain angle. Simultaneously, the gear 209 drives the cleaning brush 212 to rotate. When the number of rotations of the actuating block 215 driven by the zeolite wheel 202 is exactly the same as the number of tooth grooves of the gear 209, the actuating block 215 causes the gear 209 to rotate one revolution, thus causing the gear 209 to drive the cleaning brush 212 to rotate again to the position of the zeolite wheel 209. The zeolite wheels 202 are in contact with each other, allowing the cleaning brush 212 to clean the surface of the zeolite wheels 202, thus achieving intermittent cleaning of the surface of the zeolite wheels 202 by the cleaning brush 212. When the cleaning brush 212 rotates to be in contact with the surface of the zeolite wheels 202, it drives the first bevel gear 213 to rotate to be in a meshing state with the second bevel gear 214. The drive shaft 204 drives the first bevel gear 213 to rotate through the second bevel gear 214. The first bevel gear 213 drives the cleaning brush 212 to rotate, so that the cleaning brush 212 cleans the surface of the zeolite wheels 202.
