Description

Technical Field

[0001] This invention belongs to the field of environmental protection dust suppression technology, and is particularly for an environmental protection dust suppression device for fly ash landfills. Background Technology

[0002] Fly ash landfills are the final disposal sites for fly ash from municipal solid waste incineration. Because fly ash particles are small and lightweight, they are easily blown up by the wind, polluting the surrounding atmosphere. Therefore, it is necessary to regularly spray water to suppress dust in fly ash landfills. Currently, the most common dust suppression equipment is the mist cannon, which sprays water to suppress dust in designated areas.

[0003] The actual terrain of fly ash landfills is often uneven, with slopes and depressions. High ground (slopes) is greatly affected by airflow, and fly ash will be blown up to high altitudes along the slope. Depressions (low areas) are less affected by airflow, and fly ash will be suspended and accumulated in the depressions. Existing equipment has the following technical problems when operating on uneven terrain: If the water spray elevation angle is set to cover high ground, the large elevation angle of the fog cannon will increase the distance between the fly ash in the depression and the water mist in the high air. After the water mist falls into the depression, some of the water mist has already evaporated or come into contact with excessive fly ash, making the water mist that settles into the depression less effective at adsorbing fly ash. This will result in a poorer dust suppression effect when water is sprayed in the depression.

[0004] If the water spray elevation angle is set to cover the depression, the fog cannon's elevation angle will be small, which will prevent the fly ash on the high ground from coming into contact with the water mist. This will result in a poorer dust suppression effect on the high ground, thus affecting the existing fog cannon's dust suppression effect on uneven ground. Summary of the Invention

[0005] In order to overcome the shortcomings mentioned in the background art, the present invention provides an environmentally friendly dust suppression device for fly ash landfills.

[0006] The technical solution is: an environmental dust suppression device for fly ash landfills, comprising a base, an electric rotating frame mounted on the base, a cylinder rotatably connected to the electric rotating frame, a blower installed inside the cylinder, an electric push rod rotatably connected to the electric rotating frame, the telescopic part of the electric push rod being rotatably connected to the cylinder, the telescopic part of the electric push rod being used to push the cylinder to rotate, a water supply pipe mounted on the base, the water supply pipe being connected to a water supply ring fixedly connected to the cylinder, the water supply ring being provided with a plurality of circumferentially evenly distributed first nozzles, the cylinder being rotatably connected to and connected to symmetrically distributed branch pipes, the cylinder being provided with a driver, the driver being used to drive the symmetrically distributed branch pipes to rotate, the branch pipes being connected to a guide ring, the guide ring being fixedly connected to a branch water ring connected to the water supply pipe, the branch water ring being provided with a plurality of circumferentially evenly distributed second nozzles.

[0007] Furthermore, the inner diameter of the branch pipe gradually decreases from the point away from the flow guide ring to the point closer to it.

[0008] Furthermore, the cylinder is fixedly connected to symmetrically distributed guide plates, which are used to guide the airflow into the adjacent branch pipes.

[0009] Furthermore, the branch pipe is provided with a sealing part, and the cylinder is fixedly connected with symmetrically distributed adjusting rings. The adjusting rings rotate within adjacent sealing parts, and the adjusting rings are provided with adjusting holes. The adjusting rings are used to block adjacent branch pipes, and the adjusting holes are used to connect adjacent branch pipes.

[0010] Furthermore, the width of the adjustment hole gradually decreases from bottom to top.

[0011] Furthermore, the water delivery pipe is composed of an elastic section and a rigid section. The elastic section of the water delivery pipe is connected to the water delivery ring, and the rigid section of the water delivery pipe is equipped with a regulating valve. The valve stem of the regulating valve is fixedly connected to a spur gear, and the cylinder is fixedly connected to an arc-shaped rack. The rotation axis of the arc-shaped rack is collinear with the rotation axis of the cylinder, and the arc-shaped rack is used to drive the spur gear.

[0012] Furthermore, the cylinder is fixedly connected to a fixed frame, the fixed frame is slidably connected to a sliding frame, and a corrugated pipe is fixedly connected between the sliding frame and the fixed frame, with a notch provided at the lower part of the corrugated pipe.

[0013] Furthermore, the sliding frame is fixedly connected with a number of connecting blocks equal to the number of first nozzles on the water delivery ring, and all the connecting blocks are fixedly connected with a guide tube, which is used to block all the first nozzles of the water delivery ring.

[0014] Furthermore, the connecting block is aligned with the adjacent first nozzle on the water delivery ring, and the connecting block is provided with symmetrically distributed inclined surfaces near the water delivery ring. The inclined surfaces of the connecting block are used to guide the water flow.

[0015] Furthermore, the outer diameter of the guide tube gradually increases from near the water delivery ring to far away from it, and the guide tube is used to guide the water flow.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The present invention uses a branch water ring to supplement water spraying in uneven areas. When the dust suppression area of ​​the fly ash landfill is uneven, the elevation angle of the cylinder and branch pipes is adjusted to keep the distance between the spray point and each point on the uneven ground stable. While spraying water on high-altitude fly ash exposed to wind at higher elevations, the amount of water sprayed on relatively stationary fly ash in the depressions is ensured, thereby ensuring the dust suppression effect of the fly ash landfill. Furthermore, by setting the orifice diameter of the adjustment hole, the water pressure sprayed from the second nozzle on the branch water ring is proportional to the increase in elevation angle, ensuring that the water flow from the second nozzle on the branch water ring is sprayed to higher ground, improving the device's performance on uneven surfaces. The effect of using the device under terrain conditions is that the corrugated pipe expands to cover the initial water outlet area of ​​the first nozzle of the water supply ring, reducing the probability of external airflow affecting the water outlet section of the first nozzle of the water supply ring. This ensures the stability of the water mist spray position of the first nozzle of the water supply ring and improves the dust suppression efficiency of the device. When the device is not in use, the guide tube blocks all the first nozzles of the water supply ring to reduce the probability of the first nozzles on the water supply ring being blocked by impurities, thus ensuring the normal use of the first nozzles on the water supply ring. During the use of the device, the inclined surface of the connecting block and the guide tube work together to guide the water flow, causing the water flow to be dispersed and discharged, thus improving the dust suppression effect of the device.

Detailed Implementation

[0019] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0020] Example 1: An environmentally friendly dust suppression device for fly ash landfills, such as... Figures 1-3 As shown, the system includes a base 1, on which a control terminal (not shown) is mounted. An electric rotating frame 2, electrically connected to the control terminal, is also mounted on the base 1. A cylinder 3 is rotatably connected to the electric rotating frame 2, which drives the cylinder 3 to rotate, thus adjusting the cylinder 3's elevation angle. A blower 4, also electrically connected to the control terminal, is installed inside the cylinder 3. An electric push rod 5, also electrically connected to the control terminal, is rotatably connected to the electric rotating frame 2. The telescopic part of the electric push rod 5 is rotatably connected to the cylinder 3, and its telescopic part is used to push the cylinder 3 to rotate, thus adjusting the cylinder 3's elevation angle. A water supply pipe 6 is mounted on the base 1, connected to an external water pump. The external water pump is electrically connected to the control terminal and is not shown in the figure. The device demonstrates that the water supply pipe 6 is connected to a water supply ring 7 fixedly connected to the cylinder 3. The water supply ring 7 is equipped with several first nozzles evenly distributed around the circumference. When this device is needed to spray water to suppress dust in the fly ash landfill, the electric rotating frame 2 and the electric push rod 5 are activated via the control terminal. The telescopic part of the electric push rod 5 pushes the cylinder 3 to adjust the elevation angle of the cylinder 3. The electric rotating frame 2 drives the cylinder 3 to rotate, adjusting the state of the cylinder 3 in real time. At the same time, the external water pump and the blower 4 are activated via the control terminal. The external water pump supplies water into the water supply pipe 6. The water in the water supply pipe 6 is sprayed out through all the first nozzles of the water supply ring 7. The blower 4 sprays the sprayed water to the left to spray water to suppress dust in the fly ash landfill.

[0021] like Figures 1-4As shown, the cylinder 3 is rotatably connected to and connected to symmetrically distributed branch pipes 8. The cylinder 3 is equipped with a driver 801, which consists of a drive module in the middle and two gear sets on both sides. The drive module can be two symmetrically distributed motors (capable of driving the two gear sets to rotate in opposite directions and in the same direction) or a dual-shaft motor (only driving the two gear sets to rotate in the same direction). The two gear sets of the driver 801 drive the two branch pipes 8 to rotate respectively. The branch pipes 8 are connected to guide rings 9. The airflow from the guide ring 9 gradually tilts towards the central axis of the cylinder 3 from right to left to ensure that the airflow from the guide ring 9 is centered on the cylinder 3. The guide ring 9 is fixedly connected to a branch water ring 10 that is connected to the water supply pipe 6. The branch water ring 10 is equipped with an electrically controlled valve (not shown in the figure) and several circumferentially evenly distributed second nozzles. When the dust suppression area of ​​the fly ash landfill is uneven, for example, if the terrain on the left side of the water supply ring 7 is higher on the left and lower on the right, the elevation angle of the cylinder 3 increases, causing the first nozzle of the water supply ring 7 to spray water onto the higher ground on the left. By utilizing the downward rotation of the branch pipe 8, the guide ring... 9 drives the branch water ring 10 downward, and the second nozzle of the branch water ring 10 sprays water to supplement the depression. If the terrain in the area to the left of the water delivery ring 7 is lower on the left and higher on the right, the elevation angle of the cylinder 3 decreases, so that the first nozzle of the water delivery ring 7 sprays water to the depression on the left. By using the upward rotation of the branch pipe 8, the guide ring 9 drives the branch water ring 10 upward, and the second nozzle of the branch water ring 10 sprays water to supplement the higher ground. The branch water ring 10 sprays water to supplement the uneven area. When the dust suppression area of ​​the fly ash landfill is uneven, the elevation angle of the cylinder 3 and the branch pipe 8 is adjusted. To maintain a stable distance between the water spray point and various parts of the uneven ground, while spraying water on high-altitude fly ash when exposed to wind, the amount of water sprayed on relatively stationary fly ash in the depression is ensured, thereby ensuring the dust suppression effect of the fly ash landfill. The cylinder 3 is fixed with symmetrically distributed guide plates 11, which are used to guide the airflow into the adjacent branch pipe 8, ensuring the amount of airflow entering the branch pipe 8. The inner diameter of the branch pipe 8 gradually decreases from the distance away from the guide ring 9 to the distance closer to it, increasing the airflow pressure entering the branch pipe 8. The water flow sprayed from the second nozzle on the branch water ring 10 is blown to the left by the airflow.

[0022] When it is necessary to stop using this device to spray water to suppress dust in fly ash landfills, the electric rotating frame 2, electric push rod 5, external water pump and blower 4 are turned off through the control terminal.

[0023] like Figures 2-4As shown, branch pipe 8 is equipped with a sealing part 12, and two symmetrically distributed adjusting rings 13 are fixedly connected to the cylinder 3. Both the sealing part 12 and the adjusting ring 13 are annular. The adjusting ring 13 rotates within the adjacent sealing part 12. The adjusting ring 13 is provided with an adjusting hole 14, the width of which gradually decreases from bottom to top. When it is necessary to close the two branch pipes 8, the two branch pipes 8 are driven by the actuator 801, causing the branch pipes 8 to flip downward relative to the cylinder 3. The sealing part 12 of the branch pipe 8 rotates to be misaligned with the adjusting hole 14, the adjusting ring 13 blocks the adjacent branch pipe 8, and the solenoid valve of the branch water ring 10 is closed. When it is necessary to open the two branch pipes 8, the actuator 801... Drive the two branch pipes 8 to rotate upward relative to the cylinder 3. The sealing part 12 of the branch pipe 8 rotates to align with the adjusting hole 14. The adjusting hole 14 is connected to the adjacent branch pipe 8. Since the width of the adjusting hole 14 gradually decreases from bottom to top, the higher the elevation angle of the branch pipe 8, the smaller the connection area between the branch pipe 8 and the adjusting hole 14. The air pressure discharged from the branch pipe 8 is greater, which makes the air pressure on the water jet from the second nozzle on the branch water ring 10 greater. The water jet from the second nozzle on the branch water ring 10 is sprayed farther, ensuring that the water jet from the second nozzle on the branch water ring 10 is sprayed to a higher ground, thus improving the effect of this device in uneven terrain.

[0024] like Figure 3 and Figure 5 As shown, the water supply pipe 6 consists of an elastic section and a rigid section. The elastic section of the water supply pipe 6 is connected to the water supply ring 7. The rigid section of the water supply pipe 6 is equipped with a regulating valve 15. The valve stem of the regulating valve 15 is fixedly connected to a spur gear 16. The cylinder 3 is fixedly connected to an arc-shaped rack 17. The rotation axis of the arc-shaped rack 17 is collinear with the rotation axis of the cylinder 3. The arc-shaped rack 17 is used to drive the spur gear 16. During the upward tilting process of the cylinder 3, the cylinder 3 drives the arc-shaped rack 17 to rotate. The arc-shaped rack 17 drives the spur gear 16 through the spur gear 16. The valve stem of the regulating valve 15 is rotated, which increases the water flow rate in the regulating valve 15, ensuring the water flow rate to be sprayed to distant high ground and increasing the water mist radiation range. During the downward flipping of the cylinder 3, the cylinder 3 drives the arc rack 17 to reverse, and the arc rack 17 drives the valve stem of the regulating valve 15 to reverse through the spur gear 16, which reduces the water flow rate in the regulating valve 15. This reduces the probability of the ground near the device becoming too wet due to excessive water spray, thereby improving the dust suppression effect of the device.

[0025] Example 2: Based on Example 1, such as Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, a fixed frame 18 is fixedly connected to the cylinder 3, and a sliding frame 20 is slidably connected to the fixed frame 18. An electromagnetic slider can be installed on the cylinder 3, which drives the sliding frame 20 to move left and right. A bellows 19 is fixedly connected between the sliding frame 20 and the fixed frame 18. The lower part of the bellows 19 has a notch. Initially, the bellows 19 is in a contracted state. When the device needs to be opened, the electric slider drives the sliding frame 20 to move to the left, causing the bellows 19 to unfold and cover the left part of the water supply ring 7. This reduces the probability of external airflow affecting the initial water outlet area of ​​the first nozzle of the water supply ring 7, thereby ensuring the stability of the water mist spray position of the first nozzle of the water supply ring 7 and improving the dust reduction efficiency of the device. The sliding frame 20 is fixedly connected to a number of connecting blocks 21 equal to the number of first nozzles on the water supply ring 7. The connecting blocks 21 are aligned with the adjacent first nozzles on the water supply ring 7. Two symmetrically distributed inclined surfaces are provided on the connecting blocks 21 near the water supply ring 7. Used to guide water flow, all connecting blocks 21 are fixedly connected to the guide cylinder 22. When the sliding frame 20 moves to the left, the sliding frame 20 drives all connecting blocks 21 to move to the left, and all connecting blocks 21 drive the guide cylinder 22 to move to the left, so that the guide cylinder 22 is away from all the first nozzles of the water supply ring 7. The two inclined surfaces of the connecting blocks 21 and the guide cylinder 22 together guide the water flow. The water flow first moves along the inner and outer sides of the guide cylinder 22. Then, the water flow located outside the guide cylinder 22 moves out along both sides of the connecting blocks 21, so that the water flow is dispersed and discharged, expanding the radiation range of the water mist spray and improving the dust reduction effect of the device. During the shutdown process of the device, the guide cylinder 22 blocks all the first nozzles of the water supply ring 7 to reduce the probability of the first nozzles on the water supply ring 7 being blocked by impurities, thereby ensuring the normal use of the first nozzles on the water supply ring 7. The outer diameter of the guide cylinder 22 gradually increases from the point near the water supply ring 7 to the point far away. The guide cylinder 22 is used to guide the water flow.

The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
