Description

Technical Field

[0001] The invention relates to the technical field of spraying dust reduction, in particular to a spraying dust reduction system in a sand and dust environment of a storage yard. Background Art

[0002] When stacking materials in a yard, a large amount of suspended particles will be generated due to mechanical disturbance, wind erosion and volatilization of materials themselves. These suspended particles will float into the air and move with the air, which will not only cause harm to the respiratory tract and lungs of yard workers, but also the dust blown away by the wind will affect the environment around the yard, causing air pollution to the entire urban environment; At present, the dust reduction treatment of the stockpile yard is mostly carried out by spraying water or laying dust-proof nets. For the former, the stockpile yard is generally enclosed by fences (the mainstream spray system mostly adopts steel or concrete fence structures), and then the spray head is placed on the fences. In actual use, due to the large height of the stockpile yard, in order to minimize the spread of dust, the height of the fence will be set very high. For example, the fence height of some stockpile yards is relatively high. In the prior art (the patent publication number is CN216949823U, which discloses the municipal transformation of dust-proof spray fences), There are several spray heads on the fence, and the spray heads arranged above the fence are all directly facing the inside of the yard, so that when the water mist is just sprayed, it is easily affected by the gas and blown away, and the dispersion area of ​​​​the water mist is basically near the fence, and it cannot effectively carry out dust reduction treatment on the suspended particles far away from the side of the fence, and the dust reduction effect is general. At the same time, the sprayed water mist is affected to a certain extent, and small-sized water droplets are easy to evaporate, and large-sized water droplets settle prematurely, resulting in the water mist being unable to mix well with the suspended particles, causing the suspended particles to sink due to increased gravity. Summary of the invention

[0003] The object of the present invention is to provide a dust suppression system for a dusty environment in a storage yard, so as to solve the problems raised in the prior art.

[0004] To achieve the above object, the present invention provides the following technical solutions: A spraying dust reduction system for a dusty environment in a storage yard includes a plurality of fences, wherein the fences are composed of a bottom plate and a top plate, the bottom plate and the top plate are supported by a pipe, a plurality of spray ports are arranged on a side of the top plate away from the bottom plate, the plurality of spray ports are equidistantly arranged along the side of the top plate, a pipe is arranged inside the top plate, and the spray ports are connected to the pipe inside the top plate.

[0005] Preferably, a water pump is provided in the bottom plate, and the water pump is connected to the pipeline between the bottom plate and the top plate through a water pipe. A hemispherical plate is also provided on the side of the top plate away from the bottom plate, and an extension plate is provided on the top of the hemispherical plate. The arc center of the hemispherical plate is located on the side of the extension plate close to the spray port.

[0006] Preferably, the spraying direction of the spray port is consistent with the tangent direction of the hemispherical plate, and the axis of the spray port is perpendicular to the axis of the extension plate.

[0007] After the water pump draws water from the external source, it is transported to the pipe between the bottom plate and the top plate through the water pipe, and then transported to the spray port through the pipe. The water is sprayed out after being atomized at the spray port, and the water mist is sprayed toward the side close to the hemispherical plate. The water mist moves along the side of the hemispherical plate toward the side close to the extension plate, and moves toward the center of the yard along the extension plate. Since the spray direction of the spray port is consistent with the tangent direction of the hemispherical plate, and the axis of the spray port is perpendicular to the axis of the extension plate, the direction of the water mist when it is sprayed is opposite to the direction of the water mist moving in the yard. When the water mist moves along the hemispherical plate and the extension plate, the flow rate of the water mist is at the fastest state, and the space pressure between the hemispherical plate and the extension plate is in a low-pressure zone. At this time, the air flow rate on the side of the fence close to the yard is weak, and the space pressure is high. Therefore, the air in the yard will move under the action of air pressure, and the air will move to the side close to the fence, and then a circulation will be formed between the yard, the top plate and the extension plate. However, when the water mist is output along the extension plate, the water mist moves to the side close to the center of the yard, which will also drive the surrounding air to move, and then a layer of circulation will be generated; When several symmetrically arranged fences spray water mist together, the air in the center of the yard will move under the action of air pressure, and the air will move from the center of the yard to the edge of the yard. When the air in the center of the yard moves, the air pressure in the center of the yard is low compared to the air pressure directly above the yard, and then the air directly above the yard will flow downward, causing the air directly above the yard to flow to the center of the yard. Through the action of air pressure, the top air flows to the center of the yard, suppressing the dust in the yard within the enclosed range of the fence, avoiding dust overflow to the side outside the fence to cause air pollution.

[0008] Preferably, a fixed pile is arranged between two of the fences, a sprinkler gun is arranged on the top of the fixed pile, the sprinkler gun is composed of two groups of rotating tubes, the sprinkler gun realizes multi-directional rotation through the rotating tubes, and the rotating tubes are driven by a rotating motor.

[0009] When local dust reduction is required in the yard, the controller controls the rotating motor to start, and the rotating motor drives the two rotating tubes to rotate, so that the sprinkler gun rotates to the area facing the dust reduction, and finally the water is transported to the sprinkler gun through the pipe in the fixed pile, and the sprinkler gun sprays a water column to the local dust reduction area, so that the water in the water column mixes with the dust in the target area and settles, completing the effect of dust reduction in the local area.

[0010] Preferably, a plurality of mixing grooves are provided on the side of the top plate away from the hemispherical plate, atomization ports are provided between the mixing grooves, the atomization ports are also connected to the pipes in the top plate, and the spray angle of the atomization ports is inclined toward the side close to the mixing grooves.

[0011] Preferably, the cross-section of the mixing groove is trapezoidal, and the spacing of the mixing groove on the side away from the top plate is greater than the spacing of the mixing groove on the side close to the top plate.

[0012] The water mist sprayed from the spray port suppresses the dust in the yard to a certain extent. At this time, another part of the external water source is transported to the atomizing port through the pipeline and sprayed out from the atomizing port. Since the spray angle of the atomizing port is inclined toward the side close to the mixing tank, the water mist sprayed from the atomizing port moves along the mixing tank and flows from the top of the top plate to the side close to the bottom plate. At this time, layers of circulation have been formed in the fence, so that the air in the center of the yard will drive the dust to flow to the side close to the fence. When the mixed air moves to the side of the top plate, the water mist sprayed from the atomization port flows along the mixing tank. At this time, the flow rate in the mixing tank is greater than the flow rate of the mixed air, and then the mixed air will be sucked into the mixing tank. The cross-section of the mixing tank is trapezoidal. After the mixed air approaches the mixing tank, it flows from the side of the mixing tank away from the top plate to the side of the mixing tank close to the top plate, so that the mixed air is mixed with the water mist in the mixing tank, that is, the water mist and the dust are attached, so that the volume of the dust increases; Preferably, a right-angle groove is provided on one side of the mixing groove away from the atomization port, and a gap is provided in the middle of the right-angle groove.

[0013] Preferably, the side axis of one side of the right-angle groove is parallel to the axis of the extension plate.

[0014] When the mixed air and water mist flow from the mixing trough to the right-angle trough, since a gap is provided in the middle of the right-angle trough, and the water mist and dust are mixed and attached at this time, the air and water mist drive the dust to flow along the right-angle trough. When the dust passes through the bend of the right-angle trough, the dust is affected by the water mist, and the weight of the dust increases, and then the dust is thrown out under the action of centrifugal force, and the dust is discharged through the gap in the middle of the right-angle trough, thereby achieving the effect of dust reduction. Since the side axis of one side of the right-angle trough is parallel to the axis of the extension plate, the end of the right-angle trough plays the same role as the extension plate in guiding the flow direction of the water mist, and then the air and water mist flow through the right-angle trough to the side close to the center of the yard. The air drives the water mist to move forward during the flow, providing a certain power for the water mist to move toward the center of the yard, and when the air flows through the mixing trough and the right-angle trough, it is affected by the spacing in the trough, so that the air flow rate in the mixing trough and the right-angle trough is further increased; Through the guidance of the extension plate and the right-angle groove, the water mist forms two flow layers at high and low heights, so that the two layers of water mist flow from the fence to the center of the yard together. The air mixed with dust in the yard moves in the water mist flow layers at two heights and forms a circulation in the flow layers at two heights. The air in the yard is suppressed within a range through the flow layers at two heights to prevent the dust from spreading outward. At the same time, the air pressure is used to drive the air to flow to the side close to the fence, and the dust is reduced in the mixing trough, thereby improving the dust reduction efficiency of the yard.

[0015] Cooperating with the sprinkler gun, the overall and local dust reduction of the yard is completed. By flowing the dust in the air to the mixing tank, the water mist is prevented from floating in the air, resulting in insufficient mixing with the dust, affecting the dust reduction effect. On this basis, a certain amount of water consumption is saved, and the dust is separated to the side close to the fence, avoiding the dust from falling everywhere on the ground. After the ground is dry, the dust floats in the air again. At the same time, the water mist in the low flow layer can also continuously moisten the ground.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. Through the guidance of the extension plate and the right-angle groove, the water mist forms two flow layers at high and low heights, so that the two layers of water mist flow from the fence to the center of the yard together. The air mixed with dust in the yard moves in the water mist flow layers at two heights and forms a circulation in the flow layers at two heights. The air in the yard is suppressed within a range through the flow layers at two heights to prevent the dust from spreading outward. At the same time, the air pressure is used to drive the air to flow to the side close to the fence, and the dust is reduced in the mixing trough, thereby improving the dust reduction efficiency of the yard.

[0017] 2. Cooperate with the sprinkler gun to complete the overall and local dust reduction of the yard. By flowing the dust in the air to the mixing tank, it prevents the water mist from floating in the air, resulting in insufficient mixing with the dust and affecting the dust reduction effect. On this basis, it saves a certain amount of water consumption and separates the dust to the side close to the fence to prevent the dust from falling everywhere on the ground. After the ground is dry, it floats in the air again. At the same time, the water mist in the low flow layer can also keep the ground moist.

[0018] 3. When local dust reduction is required in the yard, the controller controls the rotating motor to start, and the rotating motor drives the two rotating tubes to rotate, so that the sprinkler gun rotates to the area facing the dust reduction, and finally the water is transported to the sprinkler gun through the pipe in the fixed pile, and the sprinkler gun sprays a water column to the local dust reduction area, so that the water in the water column mixes with the dust in the target area and settles, completing the effect of dust reduction in the local area.

The atomization ports 20 are also connected to the pipes in the top plate 12, and the spray angle of the atomization ports 20 is inclined toward the side close to the mixing grooves 19.

[0026] As a specific implementation of the present invention, the cross section of the mixing groove 19 is trapezoidal, and the spacing of the mixing groove 19 away from the top plate 12 is greater than the spacing of the mixing groove 19 close to the top plate 12 .

[0027] As a specific embodiment of the present invention, a right-angle groove 21 is provided on a side of the mixing groove 19 away from the atomization port 20 , and a gap is provided in the middle of the right-angle groove 21 .

[0028] As a specific implementation of the present invention, the side axis of one side of the right-angle groove 21 is parallel to the axis of the extension plate 15 .

[0029] Working principle of the present invention: After the water pump extracts the external water source, it is transported to the pipe between the bottom plate 11 and the top plate 12 through the water pipe, and then transported to the spray port 13 through the pipe. The water is sprayed out after being atomized at the spray port 13, and the water mist is sprayed toward the side close to the hemispherical plate 14. The water mist moves along the side of the hemispherical plate 14 toward the side close to the extension plate 15, and moves toward the center of the yard along the extension plate 15. Since the spraying direction of the spray port 13 is consistent with the tangent direction of the hemispherical plate 14, and the axis of the spray port 13 is perpendicular to the axis of the extension plate 15, the direction of the water mist when it is sprayed is opposite to the direction of the water mist moving in the yard. When the water mist moves along the hemispherical plate 14 and the extension plate 15, the flow rate of the water mist is at the fastest state, and the space pressure between the hemispherical plate 14 and the extension plate 15 is in a low-pressure area, and the air flow rate angle on the side of the fence 1 close to the yard is high pressure, and the air in the yard moves under the action of the air pressure, and the air moves to the side close to the fence 1, and then a circulation is formed between the yard, the top plate 12 and the extension plate 15. However, the water mist is output along the extension plate 15, so that when the water mist moves to the side close to the center of the yard, it will also drive the surrounding air to move, and then a layer of circulation will be generated; When several symmetrically arranged fences 1 spray water mist together, the air in the center of the yard will move under the action of air pressure, and the air will move from the center of the yard to the edge of the yard. When the air in the center of the yard moves, the air pressure in the center of the yard is lower than the air pressure directly above the yard, and the air directly above the yard will flow downward, so that the air directly above the yard flows to the center of the yard, and the dust in the yard is suppressed within the enclosed range of the fence 1 by using the air pressure and the top air to flow to the center of the yard, thereby preventing the dust from overflowing to the side outside the fence 1. The water mist sprayed from the spray port 13 suppresses the dust in the yard to a certain extent. At this time, another part of the external water source is transported to the atomizing port 20 through a pipeline and sprayed out from the atomizing port 20. Since the spray angle of the atomizing port 20 is inclined toward the side close to the mixing tank 19, the water mist sprayed from the atomizing port 20 moves along the mixing tank 19 and flows from the top of the top plate 12 to the side close to the bottom plate 11. At this time, layers of circulation have been formed in the fence 1, so that the air in the center of the yard will drive the dust to flow to the side close to the fence 1. When the mixed air moves to the side of the top plate 12, the water mist sprayed from the atomization port 20 flows along the mixing groove 19. At this time, the flow rate in the mixing groove 19 is greater than the flow rate of the mixed air, and then the mixed air will be sucked into the mixing groove 19. The cross-section of the mixing groove 19 is trapezoidal. After the mixed air approaches the mixing groove 19, it flows from the side of the mixing groove 19 away from the top plate 12 to the side of the mixing groove 19 close to the top plate 12, so that the mixed air is mixed with the water mist in the mixing groove 19, that is, the attachment of the water mist and the dust is completed, so that the volume of the dust increases; When the mixed air and water mist flow from the mixing groove 19 to the right-angle groove 21, since a gap is provided in the middle of the right-angle groove 21, and the water mist and the dust are mixed and attached at this time, the air and the water mist drive the dust to flow along the right-angle groove 21. When the dust passes through the bend of the right-angle groove 21, the dust is affected by the water mist, and the weight of the dust increases, and then the dust is thrown out under the action of centrifugal force, and the dust is discharged through the gap in the middle of the right-angle groove 21, so that the dust reduction effect is achieved. Since the side axis of one side of the right-angle groove 21 is parallel to the axis of the extension plate 15, the end of the right-angle groove 21 plays the same role as the extension plate 15 in guiding the flow direction of the water mist, and then the air and the water mist flow through the right-angle groove 21 to the side close to the center of the yard. The air drives the water mist to move forward during the flow process, providing a certain power for the water mist to move toward the center of the yard, and when the air flows through the mixing groove 19 and the right-angle groove 21, it is affected by the spacing in the groove, so that the air flow rate in the mixing groove 19 and the right-angle groove 21 will be further increased; Through the guidance of the extension plate 15 and the right-angle groove 21, the water mist forms two flow layers at high and low heights, so that the two layers of water mist flow from the fence 1 to the center of the yard together, and the air mixed with dust in the yard moves in the water mist flow layers at two heights and forms a circulation in the flow layers at two heights. The air in the yard is suppressed within a range through the flow layers at two heights to prevent dust from spreading outward. At the same time, the air pressure is used to drive the air to flow to the side close to the fence 1, and the dust reduction treatment is completed in the mixing tank 19.
