Description

A main structure of an environmental engineering atomizing cannon Technical Field

[0001] This utility model relates to the field of atomizing cannon technology, specifically to a main structure of an environmental engineering atomizing cannon. Background Technology

[0002] In the field of environmental engineering, atomizing cannons (also known as fog cannons or dust suppression fog cannons) are widely used in construction sites, mines, ports, chemical industrial parks and other places for dust suppression, exhaust gas treatment and air purification. Traditional atomizing cannons mainly use high-pressure water pumps to atomize water and then spray it through a fan.

[0003] Traditional atomizing cannons typically use a fixed spacing layout for their nozzles, making it impossible to dynamically adjust the atomization range according to actual working conditions. For example, in open spaces where large-scale dust suppression is required, the atomization coverage is insufficient; while in areas with high concentrations of dust where high-intensity atomization is needed, the spray cannot be concentrated, leading to wasted water resources or poor dust suppression effects. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a main structure for an environmental engineering atomizing cannon.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A main structure for an environmental engineering atomizing cannon includes:

[0007] The gun body assembly includes an axially extending nozzle and a positioning ring fixed to the outer edge of its air outlet end. The inner wall of the positioning ring is provided with a plurality of radially extending grooves at equal intervals in a circumferential ring.

[0008] Dynamic atomization components, including:

[0009] A flexible water spray ring is coaxially sleeved on the outside of the air outlet end of the spray nozzle;

[0010] Multiple atomizing nozzles, the base of each nozzle is fixedly connected to a flexible water spray ring and slidably embedded in a corresponding groove, the nozzle nozzle end extends toward the central axis of the air outlet end of the spray cylinder;

[0011] The power source drives the nozzle to move radially along the length of the groove.

[0012] The corresponding section of the flexible spray ring undergoes adaptive elastic deformation with the radial displacement of the nozzle, creating a dynamically adjustable atomization gap between adjacent nozzles, thereby achieving:

[0013] Diffusion atomization mode: Each nozzle moves radially outward to the maximum spacing, forming an atomization zone with the largest flow cross-section;

[0014] Concentrated atomization mode: Each nozzle contracts radially inward to form a focused atomization zone with the smallest flow cross-section.

[0015] Preferably, the flexible spray ring undergoes the following deformation in the section between adjacent nozzles as the nozzles move radially:

[0016] In the diffusion atomization mode, the distance between adjacent nozzles increases, the corresponding section is elongated and the radial cross-section becomes thinner;

[0017] In the centralized atomization mode, the distance between adjacent nozzles decreases, the corresponding section shortens, and the radial cross-section becomes thicker.

[0018] Preferably, the flexible water spray ring has a circular cross-section, with its axis coinciding with the central axis of the spray nozzle.

[0019] Preferably, the inner wall of the flexible water spray ring is provided with spiral guide ribs, which guide the water flow to form a swirling flow when the cross-section becomes thicker.

[0020] Preferably, the cylinder in the power source is axially fixed outside the spray nozzle, and the linkage ring fixed at the telescopic end of the cylinder is hinged to the linkage plate hinged to the base of each nozzle. The axial displacement of the cylinder is converted into synchronous radial movement of each nozzle through the linkage plate.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] This invention achieves passive flow regulation by deforming the cross-section of a flexible water spray ring. When the cross-section becomes thicker, the flow velocity increases but the flow rate remains constant, resulting in high-pressure jetting. When the cross-section becomes thinner, the flow velocity decreases but the coverage diffusion angle increases, thus achieving dynamic optimization of atomization performance and meeting the needs of different working conditions.

[0028] Example

[0029] As shown in Figures 1 and 2, a main structure of an environmental engineering atomizing cannon includes:

[0030] The gun body assembly includes an axially extending nozzle 1 and a positioning ring 2 fixed to the outer edge of its air outlet. The inner wall of the positioning ring 2 is provided with a plurality of radially extending grooves 21 at equal intervals in a circumferential ring.

[0031] Dynamic atomization component 3 includes:

[0032] A flexible water spray ring 31 is coaxially sleeved on the outside of the air outlet end of the spray cylinder 1;

[0033] Multiple atomizing nozzles 32, the base of each nozzle 32 is fixedly connected to the flexible water spray ring 31 and slidably embedded in the corresponding groove 21, the nozzle 32 extends towards the central axis of the air outlet of the spray cylinder 1.

[0034] Power source 4 drives nozzle 32 to move radially along the length of slide groove 21;

[0035] Among them, the corresponding section of the flexible spray ring 31 undergoes adaptive elastic deformation with the radial displacement of the nozzle 32, so that a dynamically adjustable atomization gap is formed between adjacent nozzles 32, thereby achieving:

[0036] Diffusion atomization mode: Each nozzle 32 moves radially outward to the maximum spacing, forming an atomization zone with the largest flow cross section;

[0037] Concentrated atomization mode: Each nozzle 32 contracts radially inward to form a focused atomization zone with the smallest flow cross-section.

[0038] The flexible spray ring 31 undergoes the following deformation in the section between adjacent nozzles 32 as the nozzles 32 move radially:

[0039] In diffusion atomization mode, the spacing between adjacent nozzles 32 increases, the corresponding section is lengthened and the radial cross section becomes thinner, which reduces the water flow velocity and increases the atomization coverage area.

[0040] In the centralized atomization mode, the spacing between adjacent nozzles 32 is reduced, the corresponding section is shortened and the radial cross section is thickened, which increases the water flow velocity and enhances the atomization penetration.

[0041] Deformation of the flexible water spray ring 31: When the nozzle 32 moves radially, adjacent sections of the flexible water spray ring 31 undergo elastic deformation.

[0042] The inner wall of the flexible water spray ring 31 is provided with spiral guide ribs, which guide the water flow to form a swirling flow when the cross-section becomes thicker, thereby enhancing the uniformity of atomization.

[0043] When the flow is contracted: the decrease in the circumference of the ring causes the cross-section to be compressed and thickened (the short axis increases and the water flow accelerates), resulting in a high-kinetic-energy jet with strong penetrating power. When the cross-section becomes thicker, the spiral guide ribs force the water flow to spiral forward, generating centrifugal force to enhance atomization.

[0044] When expanding outward: the annular circumference increases - the cross-section becomes thinner under tension (long axis extends, water flow slows down), wide coverage fog curtain, large adsorption range.

[0045] The flexible water spray ring 31 has a circular cross-section, with its axis coinciding with the central axis of the spray nozzle 1, such that:

[0046] When the nozzle 32 moves radially inward, the long axis of the cross-section shortens and the short axis lengthens, forming a high-speed water flow channel;

[0047] When the nozzle 32 moves radially outward, the long axis of the cross section extends and the short axis contracts, forming a low-speed diffusion water flow channel.

[0048] The cylinder 41 in the power source 4 is axially fixed outside the spray nozzle 1. The linkage ring 42 fixed at the telescopic end of the cylinder 41 is hinged to the linkage plate 43 at the base of each nozzle 32. The axial displacement of the cylinder 41 is converted into the synchronous radial movement of each nozzle 32 through the linkage plate 43.

[0049] The extension end of cylinder 41 pushes the linkage ring 42 to move axially, and the linkage ring 42 converts the axial displacement into the radial movement of nozzle 32 through the hinged linkage plate 43.

[0050] The nozzle 32 is driven to move radially by the power source 4, and in conjunction with the elastic deformation of the flexible water spray ring 31, the switching between diffusion atomization mode (large-area coverage) and concentrated atomization mode (high-intensity penetration) can be realized to meet the needs of different working conditions.

[0051] The flexible water spray ring 31 automatically adjusts its cross-sectional shape (elongating to become thinner / shortening to become thicker) as the nozzle 32 moves, passively regulating the water flow speed and flow rate. In the concentrated atomization mode, the cross-section of the flexible water spray ring 31 thickens, accelerating the water flow to form a high-pressure jet, reducing the atomized particle size to below 20μm, enhancing gas-liquid mass transfer efficiency, and making it suitable for high-requirement scenarios such as chemical waste gas treatment. In the diffusion atomization mode, the water flow slows down but the coverage area expands, increasing the dust suppression area by 50% with the same water consumption, making it suitable for large-scale dust suppression needs in construction sites, mines, and other similar locations.

[0052] The spiral guide ribs induce swirling under high-speed water flow, making the atomization distribution more uniform, avoiding local dry spraying or droplet aggregation, and improving atomization efficiency by 25%.

[0053] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
