Description

Technical Field

[0001] This invention relates to the field of dust removal equipment technology for factories, specifically to a dust removal device for industrial factories. Background Technology

[0002] Factory buildings tend to generate a lot of dust during production, especially those involving processes such as spraying, printing, chemical processing, adhesive application, and injection molding. These processes produce a significant amount of organic waste gas containing large amounts of dust, benzene, alcohols, ketones, aldehydes, esters, ethers, alkanes, and other impurities. Inhaling these organic waste gases can cause serious harm to respiratory health. Therefore, dust removal equipment is installed in all industrial plants.

[0003] Dust removal equipment typically includes a pretreatment device to pretreat large dust particles in the air. These pretreatment devices often employ spray-type dust suppression to remove most impurities from the air. However, in practical applications, the spray booth needs to continuously spray a large amount of water mist to effectively remove dust from the air, which can easily lead to a waste of water resources. To address these issues, the following solutions are proposed. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a dust removal device for industrial plants, including an activated carbon tower, an air inlet pipe connected through the side wall of the activated carbon tower, a water inlet fixedly connected to the side wall of the air inlet pipe, and two drain pipes connected through the outer wall of the air inlet pipe, and further comprising: The dust removal mechanism is fixedly connected to the inner wall of the air inlet pipe; The cleaning mechanism is fixedly connected to the inner wall of the dust removal mechanism; The limiting mechanism is fixedly connected to the outer wall of the cleaning mechanism. Before use, the equipment needs to be fixed in the required position, and then the external water pipe is connected to the water inlet. When the equipment is running, the dust removal mechanism and the cleaning mechanism will adsorb the impurities inside the air pipe and finally discharge them out through the drain pipe.

[0005] Preferably, the dust removal mechanism includes: The adsorption component is fixedly connected to the inner wall of the air inlet pipe. Drainage assembly, which is fixedly connected to the inner wall of the air inlet pipe; During equipment operation, the water from the water inlet will be evenly distributed on the inner wall of the adsorption component. When air passes through the adsorption component inside the air inlet pipe, the adsorption component will adsorb larger dust particles in the air.

[0006] Preferably, the cleaning mechanism includes: The control component is fixedly connected to the inner wall of the drainage component; The auxiliary component is fixedly connected to the inner wall of the air inlet pipe; In this process, after the air inside the inlet pipe undergoes a single adsorption by the adsorption component, it continues to descend and comes into contact with the outer wall of the auxiliary component for a second adsorption.

[0007] Preferably, the limiting mechanism includes: A rotating component is rotatably connected to the inner wall of the auxiliary component; The discharge component is fixedly connected to the bottom of the auxiliary component; After the rotating component completes uniform drainage, the wastewater that has absorbed dust will enter the inner wall of the discharge component and eventually be discharged outward from the drain pipe.

[0008] Preferably, the adsorption assembly includes a water storage ring fixedly connected to the inner wall of the air inlet pipe, a horn tube fixedly connected to the bottom of the water storage ring, a rotating ring rotatably connected to the inner wall of the water storage ring, a discharge hole opened on the side wall of the rotating ring, and several pressure plates fixedly connected to the side of the rotating ring near the water storage ring. When water is sprayed into the water storage ring through the external pipe via the water inlet, the water will first come into contact with the pressure plate and force the pressure plate to rotate along the inner wall of the water storage ring. The water accumulated inside the water storage ring will be discharged outward through the discharge hole and form a water film on the inner wall of the trumpet tube.

[0009] Preferably, the drainage component includes a V-shaped groove 1 fixedly connected to the inner wall of the air inlet pipe, an outlet 1 opened on the side wall of the V-shaped groove 1, and an outlet 2 opened on the side wall of the air inlet pipe. In this system, the inclined inner wall of the trumpet tube is not in contact with the inner top wall of the V-shaped groove. Water flowing downward along the inclined surface of the trumpet tube will enter the inner wall of the V-shaped groove and temporarily accumulate on the inner wall of the V-shaped groove.

[0010] Preferably, the control component includes a fixed block fixedly connected to the inner wall of the air inlet pipe, a sliding frame slidably connected to the outer wall of the fixed block, a floating ring fixedly connected to the top of the sliding frame, and a blocking ring fixedly connected to the end of the sliding frame away from the floating ring. The sewage accumulated inside the V-shaped channel provides buoyancy to the floating ring. There is frictional resistance between the sliding frame and the fixed block. When the sewage level exceeds the top of the floating ring, the buoyancy of the floating ring will be greater than the frictional resistance. At this time, the floating ring will drive the blocking ring to slide upward through the sliding frame and maintain a floating state for a short time. Meanwhile, the sewage accumulated inside the V-shaped channel will flow downward through the gap between the V-shaped channel and the blocking ring. Finally, the sewage is discharged outward from the drain pipe through outlet one and outlet two.

[0011] Preferably, the auxiliary component includes a hollow frame fixedly connected to the inner wall of the air inlet pipe, a hollow cone block fixedly connected to the inner wall of the hollow frame, a through hole groove opened on the inner wall of the hollow cone block, and a water inlet pipe fixedly connected to the bottom of the hollow cone block. The outer wall of the water inlet pipe is fixedly connected to the outer wall of the air inlet pipe. Before use, the external pipe needs to be connected to the outer wall of the water inlet pipe, and the external pipe will continuously transmit water to the inner wall of the through hole groove through the water inlet pipe.

[0012] Preferably, the rotating assembly includes an auger column rotatably connected to the inner wall of the water inlet pipe, a sealing cap is fixedly connected to the end of the auger column away from the water inlet pipe, and a drain outlet is provided on the side wall of the sealing cap; When water is supplied evenly through the inlet pipe, the water flowing from bottom to top will force the auger column to rotate. At the same time, the water will travel along the inner wall of the through-hole groove to the sealing cover and finally be discharged outward from the drain outlet.

[0013] Preferably, the discharge assembly includes a V-shaped groove 2 fixedly connected to the bottom of the hollow frame, a discharge outlet 3 opened on the side wall of the V-shaped groove 2, a floating ring 2 slidably connected to the inner wall of the V-shaped groove 2, and a blocking ring 2 fixedly connected to the bottom of the floating ring 2. There is resistance between the second floating ring and the second V-shaped channel. When the sewage accumulated inside the second V-shaped channel exceeds the highest position of the second floating ring, the second floating ring will drive the second blocking ring to slide upward. At this time, the sewage will flow downward through the gap between the second blocking ring and the second V-shaped channel, and be discharged outward through the third outlet and the drain pipe.

[0014] The present invention has the following beneficial effects: (1) In view of the problem that water mist dust suppression equipment wastes a lot of water, the present invention has a cleaning mechanism and a limiting mechanism inside the equipment. When water is sprayed into the water storage ring through the water inlet of the external pipe, the water flow is temporarily retained inside the water storage ring and discharged outward from the discharge hole, and a water film is formed on the inner wall of the trumpet tube. The water film will flow slowly downward along the inner wall of the trumpet tube. When the exhaust gas carrying dust flows downward at the top of the air inlet pipe, the exhaust gas will contact the outer wall of the water film. The dust particles in the exhaust gas will contact the outer wall of the water film and be adsorbed by the water film. Through the application of the above components, the water consumption of the equipment can be reduced while effectively removing larger dust particles in the exhaust gas. (2) When the water is supplied evenly in the water inlet pipe, the water from bottom to top will force the auger column to rotate. At the same time, the water will reach the sealing cover position along the inner wall of the through hole groove and finally be discharged outward from the drain outlet. A water film will be formed on the outer wall of the hollow cone block to perform secondary filtration of the exhaust gas. If high-concentration exhaust gas is to be filtered, multiple air inlet pipes can be connected end to end. After the filtration is completed in a single air inlet pipe, it will be transmitted through the pipe to the top of another air inlet pipe for reciprocating dust removal. Through the application of the above components, the contact area between the exhaust gas and the water film is increased, and the dust removal efficiency of the equipment is improved. (3) This invention utilizes the characteristic of water flowing along the inner wall of the trumpet tube. A drainage component and a cleaning mechanism are installed inside the equipment. Water flowing down the slope of the trumpet tube will enter the inner wall of the V-shaped groove and temporarily accumulate on the inner wall of the V-shaped groove. The sewage accumulated inside the V-shaped groove will provide buoyancy for the floating ring. There is frictional resistance between the sliding frame and the fixed block. When the sewage level exceeds the top of the floating ring, the buoyancy of the floating ring will be greater than the frictional resistance. At this time, the floating ring will drive the blocking ring to slide upward through the sliding frame and maintain the floating state briefly. At the same time, the sewage accumulated inside the V-shaped groove will flow downward through the gap between the V-shaped groove and the blocking ring. Finally, the sewage will be discharged from the drain pipe through the outlet 1 and outlet 2, realizing the rapid recycling of sewage and preventing sewage from adhering to the inner wall of the air inlet pipe and eventually causing scale, which will affect the transmission efficiency of the air inlet pipe. (4) This invention replaces the traditional water mist dust suppression by water flow surface adsorption, which effectively prevents the air humidity from rising to saturation while the water mist dust suppression is completed. When the air with excessive humidity passes through the activated carbon tower, the residual moisture will be absorbed by the activated carbon and force the activated carbon to expand, affecting the filtration efficiency of the activated carbon tower. By replacing the traditional water mist dust suppression with water flow surface adsorption, the impact of humid air on activated carbon is effectively reduced. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

When the equipment is running, the dust removal mechanism 1 and the cleaning mechanism 2 will adsorb the impurities inside the air pipe 14 and finally discharge them out through the drain pipe 16.

[0020] Dust removal mechanism 1 includes: Adsorption component 11 is fixedly connected to the inner wall of air inlet pipe 14. Drainage assembly 12 is fixedly connected to the inner wall of air inlet pipe 14; When filtering high-concentration exhaust gas, multiple inlet pipes 14 can be connected end to end. After filtration is completed in a single inlet pipe 14, the gas is transported through a pipeline to the top of another inlet pipe 14 for reciprocating dust removal.

[0021] Cleaning mechanism 2 includes: Control component 21 is fixedly connected to the inner wall of drainage component 12; Auxiliary component 22 is fixedly connected to the inner wall of the air inlet pipe 14; In this process, after the air inside the air inlet pipe 14 completes a single adsorption by the adsorption component 11, it continues to move downward and comes into contact with the outer wall of the auxiliary component 22 for a second adsorption.

[0022] Restricted agency 3 includes: Rotating component 31 is rotatably connected to the inner wall of auxiliary component 22; Discharge component 32 is fixedly connected to the bottom of auxiliary component 22; After the rotating component 31 completes uniform drainage, the wastewater that has absorbed dust will enter the inner wall of the discharge component 32 and eventually be discharged outward from the drain pipe 16.

[0023] Example 2, please refer to Figure 4 - Figure 12The present invention is a dust removal device for industrial plants. Based on the first embodiment, the adsorption component 11 includes a water storage ring 111 fixedly connected to the inner wall of the air inlet pipe 14. A horn tube 112 is fixedly connected to the bottom of the water storage ring 111. A rotating ring 113 is rotatably connected to the inner wall of the water storage ring 111. A discharge hole 114 is opened on the side wall of the rotating ring 113. Several pressure plates 115 are fixedly connected to the side of the rotating ring 113 near the water storage ring 111. This invention addresses the problem of excessive water waste in water mist dust suppression equipment by incorporating a cleaning mechanism 2 and a limiting mechanism 3 inside the equipment. When water is sprayed into the water storage ring 111 through the external pipe via the water inlet 15, the water flow temporarily remains inside the water storage ring 111 and is discharged outward from the outlet 114, forming a water film on the inner wall of the horn tube 112. This water film slowly flows downward along the inner wall of the horn tube 112. When the exhaust gas carrying dust flows downward from the top of the air inlet pipe 14, the exhaust gas comes into contact with the outer wall of the water film, and the dust particles in the exhaust gas come into contact with the outer wall of the water film and are adsorbed by the water film. Through the application of the above components, larger dust particles in the exhaust gas can be effectively removed while reducing the water consumption of the equipment.

[0024] The drainage assembly 12 includes a V-groove 121 fixedly connected to the inner wall of the air inlet pipe 14, an outlet 122 is provided on the side wall of the V-groove 121, and an outlet 123 is provided on the side wall of the air inlet pipe 14. The inclined inner wall of the trumpet tube 112 is not in contact with the top inner wall of the V-shaped groove 121. Water flowing down the inclined surface of the trumpet tube 112 will enter the inner wall of the V-shaped groove 121 and temporarily accumulate on the inner wall of the V-shaped groove 121.

[0025] The control component 21 includes a fixed block 211 fixedly connected to the inner wall of the air inlet pipe 14, a sliding frame 212 slidably connected to the outer wall of the fixed block 211, a floating ring 213 fixedly connected to the top of the sliding frame 212, and a blocking ring 214 fixedly connected to the end of the sliding frame 212 away from the floating ring 213. The sewage accumulated inside the V-shaped groove 121 provides buoyancy for the floating ring 213. There is frictional resistance between the sliding frame 212 and the fixed block 211. When the sewage level exceeds the top of the floating ring 213, the buoyancy of the floating ring 213 will be greater than the frictional resistance. At this time, the floating ring 213 will drive the blocking ring 214 to slide upward through the sliding frame 212 and briefly maintain the floating state. Meanwhile, the sewage accumulated inside the V-shaped groove 121 will flow downward through the gap between the V-shaped groove 121 and the blocking ring 214. Finally, the sewage is discharged outward from the drain pipe 16 through the outlet 122 and the outlet 223.

[0026] The auxiliary component 22 includes a hollow frame 221 fixedly connected to the inner wall of the air inlet pipe 14, a hollow cone block 222 fixedly connected to the inner wall of the hollow frame 221, a through hole groove 223 opened on the inner wall of the hollow cone block 222, and a water inlet pipe 224 fixedly connected to the bottom of the hollow cone block 222. Utilizing the characteristic of water flowing along the inner wall of the trumpet pipe 112, a drainage component 12 and a cleaning mechanism 2 are installed inside the device. Water flowing downwards along the slope of the trumpet pipe 112 enters the inner wall of the V-shaped groove 121 and temporarily accumulates there. The accumulated wastewater inside the V-shaped groove 121 provides buoyancy for the floating ring 213. Furthermore, there is frictional resistance between the sliding frame 212 and the fixed block 211. When the wastewater level exceeds the top of the floating ring 213, the buoyancy of the floating ring 213 will increase significantly. Due to frictional resistance, the floating ring 213 will drive the blocking ring 214 to slide upward through the sliding frame 212 and maintain a floating state briefly. At the same time, the sewage accumulated inside the V-shaped groove 121 will flow downward through the gap between the V-shaped groove 121 and the blocking ring 214. Finally, the sewage will be discharged from the drain pipe 16 through the outlet 122 and the outlet 223, realizing the rapid recycling of sewage and preventing sewage from adhering to the inner wall of the air inlet pipe 14 and eventually causing scale, which would affect the transmission efficiency of the air inlet pipe 14.

[0027] The rotating assembly 31 includes an auger column 311 rotatably connected to the inner wall of the water inlet pipe 224. A sealing cap 312 is fixedly connected to one end of the auger column 311 away from the water inlet pipe 224. A drain outlet 313 is provided on the side wall of the sealing cap 312. When water is supplied evenly through the inlet pipe 224, the water flowing from bottom to top will force the auger column 311 to rotate. At the same time, the water will travel along the inner wall of the through-hole groove 223 to the sealing cover 312 and finally be discharged outward from the drain outlet 313. A water film will be formed on the outer wall of the hollow conical block 222 to perform secondary filtration of the exhaust gas. By applying the above components, the contact area between the exhaust gas and the water film is increased, thereby improving the dust removal efficiency of the equipment.

[0028] The discharge assembly 32 includes a V-shaped groove 321 fixedly connected to the bottom of the hollow frame 221, a discharge outlet 322 opened on the side wall of the V-shaped groove 321, a floating ring 324 slidably connected to the inner wall of the V-shaped groove 321, and a blocking ring 323 fixedly connected to the bottom of the floating ring 324. In this method, water flow surface adsorption replaces traditional water mist dust suppression, effectively preventing the air humidity from rising to saturation during the dust suppression process. When the air with excessively high humidity passes through the activated carbon tower 13, the residual moisture will be absorbed by the activated carbon, causing it to expand and affecting the filtration efficiency of the activated carbon tower 13. By replacing traditional water mist dust suppression with water flow surface adsorption, the impact of humid air on the activated carbon is effectively reduced.

[0029] One specific application of this embodiment is as follows: Before use, the device needs to be fixed in the required position, and then the external water pipe is connected to the water inlet 15. When the device is running, the dust removal mechanism 1 and the cleaning mechanism 2 will adsorb the impurities inside the air pipe 14 and finally discharge them outward from the drain pipe 16.

[0030] This invention addresses the problem of excessive water waste in water mist dust suppression equipment by incorporating a cleaning mechanism 2 and a limiting mechanism 3 inside the equipment. When water is sprayed into the water storage ring 111 through the external pipe via the water inlet 15, the water flow is temporarily retained inside the water storage ring 111 and discharged outward from the outlet 114, forming a water film on the inner wall of the horn tube 112. This water film will slowly flow downward along the inner wall of the horn tube 112. When the exhaust gas carrying dust flows downward from the top of the air inlet pipe 14, the exhaust gas will come into contact with the outer wall of the water film, and the dust particles in the exhaust gas will come into contact with the outer wall of the water film and be adsorbed by the water film. Through the application of the above components, larger dust particles in the exhaust gas can be effectively removed while reducing the water consumption of the equipment. In addition, when water is supplied evenly through the inlet pipe 224, the water from bottom to top will force the auger column 311 to rotate. At the same time, the water will reach the sealing cover 312 along the inner wall of the through-hole groove 223 and finally be discharged outward from the drain outlet 313. A water film will be formed on the outer wall of the hollow cone block 222 to perform secondary filtration of the exhaust gas. Through the application of the above components, the contact area between the exhaust gas and the water film is increased, and the dust removal efficiency of the equipment is improved. In addition, when filtering high-concentration exhaust gas, multiple inlet pipes 14 can be connected end to end. After filtration is completed in a single inlet pipe 14, the gas is transported through a pipeline to the top of another inlet pipe 14 for reciprocating dust removal. Utilizing the characteristic of water flowing along the inner wall of the trumpet pipe 112, a drainage component 12 and a cleaning mechanism 2 are installed inside the device. Water flowing downwards along the slope of the trumpet pipe 112 enters the inner wall of the V-shaped groove 121 and temporarily accumulates there. The wastewater accumulated inside the V-shaped groove 121 provides buoyancy for the floating ring 213. Furthermore, there is frictional resistance between the sliding frame 212 and the fixed block 211. When the wastewater level exceeds the top of the floating ring 213, the buoyancy of the floating ring 213 will exceed the frictional resistance. Due to friction resistance, the floating ring 213 will drive the blocking ring 214 to slide upward through the sliding frame 212 and maintain the floating state briefly. At the same time, the sewage accumulated inside the V-shaped groove 121 will flow downward through the gap between the V-shaped groove 121 and the blocking ring 214. Finally, the sewage will be discharged from the drain pipe 16 through the outlet 122 and the outlet 223, realizing the rapid recycling of sewage and preventing sewage from adhering to the inner wall of the air inlet pipe 14, which will eventually cause scale and affect the transmission efficiency of the air inlet pipe 14. When the air passes through the auxiliary component 22, it will... Figure 10 The water flows along the path of J, and the water film on the outer wall of the hollowed-out cone block 222 will enter the interior of the V-shaped groove 321 through the hollowed-out frame 221; By replacing traditional water mist dust suppression with water flow surface adsorption, the problem of air humidity rising to saturation during the dust suppression process is effectively prevented. When air with excessively high humidity passes through activated carbon tower 13, the residual moisture will be absorbed by the activated carbon, causing it to expand and affecting the filtration efficiency of activated carbon tower 13. By replacing traditional water mist dust suppression with water flow surface adsorption, the impact of humid air on activated carbon is effectively reduced.

Finally, the sewage will be discharged outward from the drain pipe (16) through the outlet (122) and the outlet (123).

3. The dust removal equipment for industrial plants according to claim 2, characterized in that: The auxiliary component (22) includes a hollow frame (221) fixedly connected to the inner wall of the air inlet pipe (14), a hollow cone block (222) fixedly connected to the inner wall of the hollow frame (221), a through hole groove (223) opened on the inner wall of the hollow cone block (222), and a water inlet pipe (224) fixedly connected to the bottom of the hollow cone block (222). The outer wall of the water inlet pipe (224) is fixedly connected to the outer wall of the air inlet pipe (14). Before use, the external pipe needs to be connected to the outer wall of the water inlet pipe (224), and the external pipe will continuously transmit water to the inner wall of the through hole groove (223) through the water inlet pipe (224).

4. The dust removal equipment for industrial plants according to claim 3, characterized in that: The rotating assembly (31) includes an auger column (311) rotatably connected to the inner wall of the water inlet pipe (224). A sealing cap (312) is fixedly connected to one end of the auger column (311) away from the water inlet pipe (224). A drain outlet (313) is provided on the side wall of the sealing cap (312). When water is supplied evenly through the inlet pipe (224), the water from bottom to top will force the auger column (311) to rotate, and at the same time, the water will reach the sealing cover (312) along the inner wall of the through hole groove (223), and finally be discharged outward from the drain outlet (313).

5. The dust removal equipment for industrial plants according to claim 4, characterized in that: The discharge assembly (32) includes a V-shaped groove two (321) fixedly connected to the bottom of the hollow frame (221), a discharge outlet three (322) is provided on the side wall of the V-shaped groove two (321), a floating ring two (324) is slidably connected to the inner wall of the V-shaped groove two (321), and a blocking ring two (323) is fixedly connected to the bottom of the floating ring two (324). There is resistance between the second floating ring (324) and the second V-shaped channel (321). When the sewage accumulated inside the second V-shaped channel (321) exceeds the highest position of the second floating ring (324), the second floating ring (324) will drive the second blocking ring (323) to slide upward. At this time, the sewage will flow downward through the gap between the second blocking ring (323) and the second V-shaped channel (321) and be discharged outward through the third outlet (322) and the drain pipe (16).
