Technical Field

If the waste gas is discharged directly, it will pollute the environment. At present, the market generally uses a cyclone plate tower that is easy to clean to purify the waste gas. However, the cyclone plate tower that is easy to clean on the market either directly discharges the waste gas to the outside after centrifugal separation, which will cause a large noise due to the excessive exhaust speed, which will form noise pollution; or an additional diffuser or throttle valve is installed to control the exhaust speed, but this method is not only costly, but also inconvenient for later maintenance.
[0003] At present, a cyclone plate tower on the market that is easy to clean is not only insufficient in exhaust, but also the sediment in the overflow groove between the cyclone plate and the tower body easily blocks the liquid outlet. This requires regular cleaning of the sediment in the overflow groove between the cyclone plate and the tower body. However, the commonly used cleaning methods are either strong impact with a high-pressure water gun or grabbing with mechanical equipment. When using a high-pressure water gun for impact, not only water resources are wasted, but also the cyclone plate is easily damaged. Mechanical equipment is not only expensive, but can only remove large pieces of sediment. Moreover, neither the high-pressure water gun nor the mechanical equipment can remove the sediment attached to the liquid outlet. Utility Model Content

[0017] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.
[0018] like Figure 1 to Figure 3As shown, the utility model discloses a cyclone plate tower which is easy to clean, comprising: a tower body 1, an air inlet 11 is provided on the side wall of the tower body 1, an air outlet 12 is provided on the top wall of the tower body 1, a diffusion cyclone plate 2 and a plurality of convergence cyclone plates 3 are sequentially arranged in the tower body 1 from top to bottom, in this embodiment, the number of the convergence cyclone plates 3 is two, and a blind plate 4 is arranged at the axis of the diffusion cyclone plate 2 and the convergence cyclone plate 3, if the blind plate 4 is not arranged at the axis of the diffusion cyclone plate 2 and the convergence cyclone plate 3, part of the gas will move directly from the axis, and all the gas cannot contact with the blades, reducing the diffusion The diffusion swirl plate 2 and the gathering swirl plate 3 have a guiding effect on the gas. The diffusion swirl plate 2 and the gathering swirl plate 3 are coaxially arranged with the tower body 1. The swirl plate is a prior art. In this embodiment, the difference between the diffusion swirl plate 2 and the gathering swirl plate 3 is that the inclination angles of the blades are different. The inclination angle of the blades determines the rotation radius and speed of the gas entering the swirl plate. The inclination angle of the blades of the diffusion swirl plate 2 is small, generally between 30° and 45°. When the airflow passes through the blades with a small inclination angle, the rotation radius is large and the flow rate is slow. It will rotate and diffuse around. The inclination angle of the blades of the gathering swirl plate 3 is large, generally between 60° and 80°. The airflow passes through the blades with a small inclination angle. When the blades have a large inclination angle, the rotation radius is small, the flow rate is fast, the centrifugal force is large, and the impurities in the gas are easily separated under the action of the centrifugal force. The diffusion swirl plate 2 is located at the air outlet 12 on the top of the tower body 1. By setting two converging swirl plates 3, the exhaust gas can be centrifugally separated twice, thereby improving the treatment effect of the exhaust gas. The diffusion swirl plate 2 is set at the air outlet 12 to diffuse and reduce the speed of the gas, thereby preventing the excessively fast discharge speed from causing a large noise. A spray pipe 5 is set below the diffusion swirl plate 2, and the converging swirl plates 3 are all located below the spray pipe 5. The water outlet end of the spray pipe 5 is located at the converging swirl plate 3. At the axis, the spray pipe 5 can evenly spray cooling water on the uppermost converging cyclone plate 3, so that the cooling water can form a uniform water curtain on the blades of the uppermost converging cyclone plate 3, thereby increasing the contact area between the exhaust gas and the water curtain, and allowing the water vapor in the exhaust gas to quickly condense into water. A collecting tank 13 is provided in the tower body 1, and the collecting tank 13 is located below the lowermost converging cyclone plate 3. A regular sewage discharge device 14 is provided at the bottom of the tower body 1. The regular sewage discharge device 14 is a prior art. Since impurities and wastewater will always fall to the bottom of the tower body 1, the bottom of the tower body 1 can be regularly cleaned through the regular sewage discharge device 14.
[0019] The tower body 1 is provided with three inspection ports, each of which corresponds to the diffusion swirl plate 2 and the convergence swirl plate 3 respectively. An inspection window 15 is provided on the inspection port. The convergence swirl plate 3 is provided with an overflow trough 31 connected to the inner wall of the tower body 1. Two liquid outlets are symmetrically provided on the bottom wall of the overflow trough 31, one of which is located on one side of the inspection port. A funnel tube 32 is welded in the liquid outlet hole. The top of the funnel tube 32 is not higher than the bottom inner wall of the overflow trough 31. A liquid outlet pipe 33 is welded at the bottom of the funnel tube 32. The liquid outlet pipe 33 is inclined downward toward the axis of the tower body 1. A detachable overflow pipe 34 is provided in the funnel pipe 32. The overflow pipe 34 is in a hemispherical shape. An external thread section is provided at the lower part of the overflow pipe 34. An internal thread is provided on the top inner wall of the funnel pipe 32. The overflow pipe 34 is threadedly connected to the funnel pipe 32. When droplets containing fine dust remain in the overflow trough 31, most of the fine dust will settle on the bottom inner wall of the overflow trough 31. When the liquid in the overflow trough 31 flows out of the overflow pipe 34, only a small amount of fine dust remains. In this way, the overflow pipe 34 will not be blocked, and the fine dust is not easy to adhere to the inner wall of the overflow pipe 34. In the overflow groove 31, an annular filter that can rotate along the overflow groove 31 is arranged, and the annular filter comprises: an annular filter screen 6 made of metal material, an outer clamping ring 61 is arranged on the outer ring of the annular filter screen 6, and an inner clamping ring 62 is arranged on the inner ring of the annular filter screen 6. The annular filter screen 6 is laid in the overflow groove 31, so that the fine dust deposited in the overflow groove 31 will be deposited on the annular filter screen 6. Two circular notches are arranged on the annular filter screen 6, and the two circular notches are respectively mounted on the two overflow pipes 34. The inner clamping ring 62 on the annular filter screen 6 is clamped on the inner wall of the overflow groove 31 and leaves There is a gap, the outer clamping ring 61 of the annular filter 6 is clamped on the outer wall of the overflow groove 31 with a gap. After the annular filter is set in the overflow groove 31, since the annular filter 6 is made of metal, and the outer clamping ring 61 and the inner clamping ring 62 are also made of metal, the annular filter has a certain weight, and the gas in the tower body 1 cannot only act on the inner side of the inner clamping ring 62 when it moves at high speed. At most, the inner clamping ring 62 can be blown to tilt, and the inner clamping ring 62 cannot be blown away from the inner wall of the overflow groove 31. Therefore, when the exhaust gas is centrifuged, the annular filter will not be separated from the overflow groove 31.In this embodiment, the inner snap ring 62 and the outer snap ring 61 have the same structure. Take the outer snap ring 61 as an example: the outer snap ring 61 includes: an outer U-shaped ring 611 and an inner U-shaped ring 612. The outer ring of the annular filter 6 is placed on the outer side wall of the inner U-shaped ring 612. The outer U-shaped ring 611 is clamped on the outer side wall of the inner U-shaped ring 612 and is tightened by interference fit. The inner U-shaped ring 612 is clamped on the outer wall of the overflow groove 31 and is clearance fit. Therefore, the connection structure between the inner snap ring 62 and the annular filter 6 is: the inner ring of the annular filter 6 is placed on the inner snap ring 62. On the inner U-shaped ring, the outer U-shaped ring of the inner snap ring 62 is clamped on the inner U-shaped ring of the inner snap ring 62 and has an interference fit. The inner U-shaped ring of the inner snap ring 62 is clamped on the inner wall of the overflow groove 31 and has a clearance fit. In this way, the outer snap ring 61 and the inner snap ring 62 can be rotated, thereby rotating the annular filter screen 6. When the annular filter screen 6 rotates, since the overflow pipe 34 is hemispherical in shape, the circular notch on the annular filter screen 6 can move along the arc-shaped outer side wall of the overflow pipe 34, thereby preventing the annular filter screen 6 from being torn and damaged by the overflow pipe 34 when being pulled.
[0020] The exhaust gas enters the tower body 1 from the air inlet 11, and the exhaust gas first contacts the lowest converging cyclone plate 3 for primary treatment. Under the guidance of the lowest converging cyclone plate 3, the exhaust gas will rotate and rise at a relatively high speed. The condensed water and fine dust formed after the cooling of part of the water vapor in the exhaust gas will be separated under the action of centrifugal force and thrown into the overflow trough 31. After the water vapor condenses, the water and fine dust are retained in the overflow trough 31. The exhaust gas becomes relatively clean after the primary treatment. After the primary treatment, the exhaust gas The gas continues to move upward and contacts the top converging cyclone plate 3 for secondary treatment. Under the guidance of the top converging cyclone plate 3, the gas will rotate and rise at a relatively high speed. The condensed water and fine dust formed after the residual water vapor in the gas is cooled will continue to be separated under the action of centrifugal force. After the two-stage treatment, the remaining small amount of gas moves upward and contacts the diffusion cyclone plate 2. Under the guidance of the diffusion cyclone plate 2, it diffuses and slows down toward the inner wall of the tower body 1, and is discharged from the air outlet 12.
[0021] When the converging cyclone plate 3 is centrifugally treating the exhaust gas, the spray pipe 5 will spray cooling water, which will directly act on the blades of the uppermost converging cyclone plate 3 to form a water curtain. When the rotating gas contacts the water curtain, the water vapor will directly condense into water and wrap the fine dust to form droplets. The water and the droplets will be thrown into the overflow trough 31 under the centrifugal force. The fine dust will be precipitated and separated in the overflow trough 31. The fine dust will settle on the annular filter screen 6. When the liquid level in the overflow trough 31 reaches above the overflow pipe 34, the liquid will flow out from the overflow trough 31. The flow tube 34 flows into the funnel tube 32 and flows downward from the liquid outlet pipe 33. The liquid flowing out of the liquid outlet pipe 33 of the uppermost converging cyclone plate 3 flows to the blind plate 4 of the lower converging cyclone plate 3, and then is diverted from the blind plate 4 to each blade, forming a water curtain on each blade. In this way, the exhaust gas can be brought into contact with the cooling water during the primary treatment, thereby improving the gas-liquid separation efficiency during the primary treatment. The liquid overflowing from the overflow groove 31 in the lowermost converging cyclone plate 3 enters the collecting tank 13 through the liquid outlet pipe 33.
[0022] When it is observed from the inspection window 15 that the amount of dust deposited in the overflow trough 31 is too much, it needs to be cleaned. When cleaning, open the inspection window 15 on the inspection port corresponding to the convergent cyclone plate 3, and screw down the overflow pipe 34 near the inspection window 15. At this time, the accumulated water in the overflow trough 31 flows directly out of the funnel pipe 32. After the accumulated water in the overflow trough 31 is discharged, use a shovel to shovel out the sediment accumulated on the annular filter screen 6 at the inspection port. When the sediment on the annular filter screen 6 near the inspection port is shoveled clean, the annular filter screen 6 is cleaned. Rotate to move the other uncleaned parts of the annular filter 6 to the inspection port for cleaning, so that there is no need to use a high-pressure water gun or mechanical equipment for cleaning. When the sediment on the annular filter 6 is cleaned, rotate the annular filter 6 to align one of the circular notches with the funnel tube 32 near the inspection port. At this time, the other circular notch is mounted on the overflow pipe 34 away from the inspection port. Then, the disassembled overflow pipe 34 is passed through the circular notch and reinstalled on the funnel tube 32 near the inspection port, and the inspection window 15 is closed.
[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or replaced by equivalents, and any modification or equivalent replacement that does not depart from the spirit and scope of the utility model should be included in the scope of protection of the claims of the utility model.
