Description

Technical Field

[0001] This application relates to the field of waste gas treatment technology, and in particular to a tower-type gas diversion structure. Background Technology

[0002] Industrial production processes generate a large amount of waste gas, which often requires purification before being discharged. Waste gas purification mainly targets industrial waste gases generated in industrial sites, such as particulate matter, flue gas, odorous gases, and toxic and harmful gases. Common waste gas purification methods include factory flue gas purification, workshop dust purification, organic waste gas purification, odor purification, acid and alkali waste gas purification, and chemical waste gas purification. Accordingly, a large number of waste gas purification equipment have appeared on the market, with spray purification towers being one type.

[0003] In existing purification towers, the exhaust gas is blown horizontally into the tower from the bottom by a blower. The exhaust gas flows upwards without any treatment and is adsorbed by the activated carbon particles in the packing particle adsorption area of ​​the tower. However, because the exhaust gas has not undergone any treatment, especially the larger particles in the exhaust gas are not absorbed by the liquid at the bottom of the tower, the high flow velocity of the exhaust gas and the presence of large-diameter particles make the micropores in the activated carbon particles easy to be blocked. As a result, the activated carbon particles are not very effective in adsorbing and treating particulate matter and impurities in the exhaust gas, which affects the purification efficiency.

[0004] Therefore, there is a need for a tower-type gas diversion structure that helps remove large particles from exhaust gas. Utility Model Content

[0005] Therefore, it is necessary to provide a tower-type gas diversion structure, the specific technical solution of which is as follows.

[0006] A tower-type gas diversion structure includes a tower body, an air inlet at the bottom of the tower body, and an exhaust port at the top of the tower body. A liquid absorption chamber is provided at the bottom of the tower body. A diversion cylinder communicating with the air inlet is provided above the liquid absorption chamber in the tower body. The diversion cylinder extends horizontally into the interior of the tower body. A diversion outlet is provided on the bottom wall of the diversion cylinder. Multiple gas diversion plates of different heights are evenly spaced inside the diversion cylinder at the diversion outlet, and the multiple gas diversion plates are arranged sequentially from low to high.

[0007] Furthermore, the outer edge surface of the gas diversion plate is an arc-shaped structure that fits against the inner wall of the diversion cylinder, and the bottom ends of the multiple gas diversion plates are arranged flush.

[0008] Furthermore, the outer walls on both sides of the diversion cylinder are provided with transverse sliding grooves, and the inner walls of the tower are provided with horizontally arranged spring telescopic rods on both sides, with the ends of the spring telescopic rods being provided with support blocks that can be slidably connected to the transverse sliding grooves.

[0009] Furthermore, the end face of the support block is provided with a wedge surface.

[0010] Furthermore, a wire mesh demister is provided inside the tower body above the diversion cylinder.

[0011] Furthermore, a cone-shaped section, narrow at the top and wide at the bottom, is provided above the wire mesh demister inside the tower body. A gas-liquid separator is provided at the top of the cone-shaped section. The gas-liquid separator includes a mesh cylinder connected to the top of the cone-shaped section and a perforated plate disposed inside the mesh cylinder. A drain port adapted to the bottom end of the cone-shaped section is provided on the side wall of the tower body.

[0012] Furthermore, a packing adsorption area is provided inside the tower body above the gas-water separator, and the packing adsorption area is filled with an activated carbon adsorption structure.

[0013] Compared with existing technologies, this utility model has the following beneficial effects:

[0014] The tower-type gas diversion structure of this utility model has a diversion cylinder installed at the air inlet of the tower body. The gas diversion plate inside the diversion cylinder can change the flow direction of the exhaust gas to downward flow. The exhaust gas flows downward and comes into contact with the liquid in the liquid absorption chamber of the tower body. Most of the harmful particles in the exhaust gas are absorbed by the liquid in the liquid absorption chamber, thereby achieving preliminary purification of the exhaust gas. This avoids large particles in the exhaust gas from clogging the activated carbon pores in the tower body, thus improving the overall purification efficiency of the purification tower for exhaust gas.

[0029] Reference Figures 1-6 As shown, this embodiment provides a tower-type gas diversion structure, including a tower body 1, an air inlet 2 at the bottom of the tower body 1, and an exhaust port at the top of the tower body 1. The tower body 1 is provided with a packing adsorption area 18 filled with an activated carbon adsorption structure. The bottom of the tower body 1 is provided with a liquid absorption chamber 4. A diversion cylinder 5 communicating with the air inlet 2 is provided above the liquid absorption chamber 4 in the tower body 1. The two ends of the diversion cylinder 5 are connected and extend horizontally into the interior of the tower body 1. The bottom wall of the diversion cylinder 5 is provided with a diversion outlet 6. Multiple gas diversion plates 7 of different heights are evenly spaced at the diversion outlet 6 in the diversion cylinder 5. The multiple gas diversion plates 7 are arranged sequentially from low to high, that is, the distance between the multiple gas diversion plates 7 and the top of the inner wall of the diversion cylinder 5 gradually decreases from the outer end to the inner end of the diversion cylinder 5.

[0030] The tower-type gas diversion structure of this utility model has a diversion cylinder 5 connected to the air inlet 2 inside the tower body 1. The diversion cylinder 5 can guide the exhaust gas entering from the air inlet 2 to a position close to the center of the tower body 1. Then, the bottom of the diversion cylinder 5 is provided with a diversion outlet 6 and a vertically arranged gas diversion plate 7 is provided inside the diversion cylinder to change the flow direction of the exhaust gas to downward flow and reduce the flow velocity of the exhaust gas. The exhaust gas flows downward and comes into contact with the liquid in the liquid absorption chamber 4 of the tower body 1. Most of the harmful particles in the exhaust gas are absorbed by the liquid in the liquid absorption chamber 4, thereby achieving preliminary purification of the exhaust gas and avoiding large particles in the exhaust gas from clogging the activated carbon pores in the tower body 1, thus improving the overall purification efficiency of the purification tower for exhaust gas.

[0031] Specifically, refer to Figures 1-4 The outer edge surface of the gas diversion plate 7 is an arc-shaped structure that fits against the inner wall of the diversion cylinder 5, and the bottom ends of the multiple gas diversion plates 7 are arranged flush. The multiple gas diversion plates 7 can form multiple gas outlet channels at the diversion outlet 6, allowing the waste gas in the diversion cylinder 5 to flow into these channels, then be guided downwards to fully contact the liquid below. The liquid below fully absorbs the harmful particulate matter in the waste gas, thus purifying it.

[0032] Specifically, refer to Figures 4-6 The outer walls of the two sides of the diversion cylinder 5 are provided with transverse sliding grooves 8, and the inner walls of the tower body 1 are provided with horizontally arranged spring telescopic rods 9. The ends of the spring telescopic rods 9 are provided with support blocks 10 that can be slidably connected with the transverse sliding grooves 8. The spring telescopic rods 9 and support blocks 10 provided in the tower body 1 can reliably support the diversion cylinder 5 and prevent the inner end of the diversion cylinder 5 from falling. When installing the diversion cylinder 5, the diversion cylinder 5 is horizontally inserted into the tower body 1. The support blocks 10 on the spring telescopic rods 9 located in the tower body 1 can slide into the transverse sliding grooves 8. The support blocks 10 support the diversion cylinder 5 and prevent the inner end of the diversion cylinder 5 from falling due to gravity when it is inserted into the tower body 1, causing the entire diversion cylinder 5 to tilt and affecting the assembly speed.

[0033] Specifically, refer to Figure 6 The end face of the support block 10 is provided with a wedge surface 11. The function of the wedge surface 11 on the end face of the support block 10 is that when the diverter cylinder 5 is horizontally inserted into the tower body 1, the inner end face of the diverter cylinder 5 contacts the wedge surface 11 of the support block 10. When the diverter cylinder 5 moves horizontally, it squeezes the wedge surface 11 of the support block 10, so that the extension section of the support block 10 and the spring extension rod 9 can retract outward, and the support block 10 can slide into the transverse slide groove 8 along the outer wall of the diverter cylinder 5.

[0034] Furthermore, the support block 10 is connected to the telescopic section of the spring telescopic rod 9 by a thread. The support block 10 is provided with a threaded sleeve that is connected to the telescopic section of the spring telescopic rod 9, which can quickly adjust the distance between the support block 10 and the inner wall of the tower body 1 to meet the needs of supporting the diversion cylinder 5 of different diameters.

[0035] Specifically, refer to Figure 1 and Figure 2 Inside the tower body 1, above the diversion cylinder 5, there is a wire mesh demister 12. The wire mesh demister 12 includes multiple stacked wire meshes. The wire mesh demister 12 is a conventional demisting structure that can absorb the mist collected after the exhaust gas flows to the liquid surface.

[0036] Specifically, refer to Figure 1 and Figure 2 Inside the tower body 1, above the wire mesh demister 12, there is a cone 13 that is narrow at the top and wide at the bottom. The bottom end of the cone 13 is fixedly connected to the inner wall of the tower body 1. The top of the cone 13 is equipped with a gas-liquid separator 14. The gas-liquid separator 14 includes a mesh cylinder 15 connected to the top end of the cone 13 and a perforated plate 16 disposed inside the mesh cylinder 15. The side wall of the tower body 1 is provided with a drain port 17 that corresponds to the bottom end of the cone 13. When the exhaust gas flows upward and passes through the mesh cylinder 15 and the perforated plate 16 of the gas-liquid separator 14, water droplets will form on the mesh cylinder 15 and the perforated plate 16, thereby removing most of the moisture in the exhaust gas. Some water droplets can flow along the outer wall of the mesh cylinder 15 to the outer conical surface of the cone 13, and then flow to the drain port 17, from which they can be discharged.

[0037] Specifically, a packing adsorption area 18 is provided inside the tower body 1 above the gas-liquid separator 14, and the packing adsorption area 18 is filled with an activated carbon adsorption structure. After most of the particles are absorbed by the liquid, the wire mesh demister 12 removes mist, and the gas-liquid separator 14 removes water, the exhaust gas flows to the activated carbon adsorption structure. The exhaust gas flows through the pores of the activated carbon adsorption structure, and the small harmful particulate matter in the exhaust gas is quickly adsorbed by the activated carbon, effectively purifying the exhaust gas with fast purification speed and good effect.

[0038] Working process: The exhaust gas enters the diversion cylinder from the air inlet 2. The gas diversion plate 7 inside the diversion cylinder changes the flow direction of the exhaust gas to downward. The exhaust gas flows downward and comes into contact with the liquid in the liquid absorption chamber 4 of the tower body 1. Most of the harmful particles in the exhaust gas are absorbed by the liquid in the liquid absorption chamber 4, thereby achieving preliminary purification of the exhaust gas. This avoids large particles in the exhaust gas from clogging the activated carbon pores in the tower body 1, and improves the overall purification efficiency of the purification tower for exhaust gas.

[0039] The exhaust gas then flows upward and passes through the wire mesh demister 12 for demisting; it then continues to flow upward and passes through the gas-water separator 14 for water removal.

[0040] After undergoing multiple purification processes, the exhaust gas continues to flow upwards to the activated carbon adsorption structure. The exhaust gas flows through the pores of the activated carbon adsorption structure, and small harmful particulate matter in the exhaust gas is quickly adsorbed by the activated carbon. Moreover, the particulate matter in the exhaust gas will not clog the pores of the activated carbon, effectively purifying the exhaust gas with fast purification speed and good effect.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The above embodiments only illustrate one or more implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
