Traditional air purification equipment often focuses on small-scale indoor air purification, and has limited processing capacity for high-concentration dust, smoke and haze. Although some large-scale industrial dust removal equipment can handle a large amount of dust, the equipment is bulky and fixedly installed, making it difficult to use it flexibly in different specific occasions, especially for scenarios that need to be operated in different locations, such as different areas of building demolition sites or different outdoor work sites, mine blasting excavation sites, and tunnel excavation sites, which cannot meet the needs of fast mobile air purification. Moreover, most of the existing air purification technologies can only deal with a single type of pollutant in dust or smoke, and lack a comprehensive equipment that can simultaneously and efficiently handle high dust, high smoke and high haze. This results in that in these specific occasions, workers are still exposed to severely polluted air for a long time, and production equipment is also damaged by corrosion, blockage, etc. due to being in a harsh air environment for a long time, thus affecting the service life of the equipment and the health of the workers.

The high-voltage electrostatic adsorption net at the air inlet end of the hair dryer can effectively adsorb tiny particles in the surrounding high dust, high smoke and high haze. The particles are adsorbed and flow back to the front of the hair dryer under the action of static electricity, thereby preliminarily purifying the air around the hair dryer. When the air is blown out through the axial flow fan inside the hair dryer, the negative ion emission module at the air outlet end further improves the air quality.

Through the purification process, the polluted air around the equipment can be quickly and efficiently purified, pollutants can be removed, and the air can be restored to fresh and comfortable air, which greatly improves the air quality in specific (high dust, high smoke, high haze) occasions.

[0014] 2) The mounting portion arranged at the bottom of the air purification device of the present invention can be installed with multiple mounting platforms, which makes it convenient to move the device in different environments. No matter it is different working areas in a factory workshop, or different working locations such as a construction and demolition site, a mine blasting site, and a tunnel operation site, it can be easily moved to the position where the air needs to be purified. It can purify and remove pollutants from all spaces with high dust, high smoke, and high haze, thereby achieving all-round purification of polluted air spaces. The mounting portion arranged can also fix the device on a vehicle-mounted platform, thereby increasing the flexibility of the device. The protective component adopts a detachable upper box body and a lower box body structure, and an arc groove is provided on the inner side for stable connection with the hair dryer barrel, thereby facilitating the installation and disassembly of the air cannon mechanism and facilitating the maintenance and inspection of the equipment. At the same time, the protective component arranged can also effectively protect the air cannon mechanism and increase the service life of the device. Compared with traditional single-function air purification equipment, the device has stronger applicability, which can not only protect the health of the staff, but also reduce the damage of polluted air to the production equipment, thereby further extending the service life of the equipment.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] Example 1

[0029] See also Figure 1-7The present invention provides the following technical solutions: a device for purifying air for removing high dust, high smoke and high haze in specific occasions, comprising a detachable protection component 100, a plurality of wind gun mechanisms 200 are detachably installed inside the protection component 100, and a power supply 110, an electrostatic generator 120, a water tank 130 and a control box 140 are installed inside the bottom of the protection component 100;

[0030] The air cannon mechanism 200 includes a hair dryer 210, the air inlet end of the hair dryer 210 is provided with a high-voltage electrostatic adsorption net 220 with an outer folded edge structure, the air outlet end of the hair dryer 210 is installed with a first support frame 230, the first support frame 230 is connected to a mounting frame 240 extending from the air outlet end of the hair dryer 210, one end of the mounting frame 240 is connected to a second support frame 260 through a plurality of connecting rods 250, a plurality of negative ion emission modules 270 are installed on the outside of the second support frame 260, the discharge needle 271 of the negative ion emission module 270 is arranged parallel to the air outlet direction of the hair dryer 210, an axial flow fan 280 is installed inside the hair dryer 210, and a plurality of spray nozzles 290 are also installed on the inside of the first support frame 230.

[0031] Specifically, when the axial flow fan 280 rotates, an air flow channel is formed in the hair dryer 210. When air containing high dust, high smoke, and high haze enters the hair dryer 210, the high-voltage electrostatic adsorption net 220 of the outer folded edge structure at the air inlet end can generate an electrostatic field. Under the action of the electrostatic field, tiny particles with electric charge in the air are adsorbed around the adsorption net due to the electrostatic adsorption principle, thereby achieving a preliminary purification effect. The air that has been preliminarily purified is pushed toward the air outlet end of the hair dryer 210. When the air is blown out of the hair dryer 210, the negative ion emission module 270 starts working, and the released negative ions can combine with the smoke and dust in the air, so that the polarity of the smoke and dust in the air is transferred, so that the smoke and dust settle to the ground.

[0032] The water in the water tank 130 is then transported to the spray nozzle 290 through a water pump. The water mist sprayed from the spray nozzle 290 can moisten the air. In the moist air, tiny particles are more likely to gather together to form larger particles, which are then settled down, further improving the air purification effect, especially for those tiny particles that still remain after electrostatic adsorption and negative ion treatment, ensuring the purification effect, and then using the device to quickly and efficiently purify the air, remove pollutants in high dust, high smoke, and high haze, and improve air quality;

[0033] The first support frame 230 and the plurality of connecting rods 250 cooperate with the second support frame 260 to provide a stable installation for the negative ion emission module 270, and place the negative ion emission module 270 outside the hair dryer 210. While ensuring the effective treatment of harmful dust and smoke molecules, it is also convenient for personnel to disassemble, assemble and maintain the negative ion emission module 270 and other components.

[0034] In order to increase the overall safety of the device, a protective net may also be installed outside the high-voltage electrostatic adsorption net 220 and fixed to the air inlet end of the hair dryer 210 .

[0035] In this embodiment, the high-voltage electrostatic adsorption net 220 is a flat net, a convex net or a concave net, and the high-voltage electrostatic adsorption net 220 is provided with at least one layer.

[0036] Specifically, when the high-voltage electrostatic adsorption net 220 is a flat net, when the axial flow fan 280 rotates to allow air to enter the hair dryer 210, its flat surface generates a uniform electrostatic field, which can effectively adsorb charged tiny particles entering perpendicular to the net surface; when it is a convex net, the surface area of ​​the high-voltage electrostatic adsorption net 220 increases, and the electric field strength at the vertex is relatively large. When air enters, the convex structure guides the airflow to change, and the particles near the vertex are first strongly adsorbed, and the adsorption range can be expanded to capture particles at more angles; when the high-voltage electrostatic adsorption net 220 is a concave net, the high-voltage electrostatic adsorption net 220 can make the air converge, the air flow rate in the central area is slow, and the particles are more easily adsorbed in the concave surface due to the flow rate and electrostatic adsorption force;

[0037] When the high-voltage electrostatic adsorption net 220 is a multi-layer adsorption net, each layer generates an independent electrostatic field, and the air passes through in sequence, similar to multi-stage filtration, which can significantly improve the adsorption efficiency of tiny particles in high dust, high smoke, and high haze.

[0038] In this embodiment, the spray nozzle 290 is detachably connected to the inner side of the first support frame 230 via a throat clamp.

[0039] Specifically, the spray nozzle 290 is installed in a detachable connection manner using a throat clamp, which makes it convenient for personnel to maintain and replace the spray nozzle 290. When the spray nozzle 290 is blocked or damaged, the throat clamp can be easily loosened to remove the spray nozzle for cleaning or replacement without complicated tools, ensuring that the spray nozzle 290 remains in good working condition, thereby ensuring the air purification effect of the air purification device.

[0040] In this embodiment, the outer side of the blower tube 210 of the blaster mechanism 200 is provided with reinforcing ribs 211, which extend along the axial direction of the blower tube 210, and the distances between adjacent reinforcing ribs 211 are equal.

[0041] Specifically, when the axial flow fan 280 rotates at high speed and generates vibration, the reinforcing ribs increase the structural rigidity of the hair dryer 210, and the axial extension can effectively resist axial and circumferential deformation. The adjacent reinforcing ribs 211 are equidistant so that when the hair dryer 210 is subjected to external force (such as the centrifugal force of the axial flow fan 280, the impact force of air, etc.), the force is evenly distributed on each reinforcing rib 211. In a complex air flow environment with high dust, high smoke, and high haze, the impact force can be dispersed to prevent deformation or damage caused by excessive local force, thereby ensuring the stable operation of the hair dryer 210, and ensuring the normal operation of the wind cannon mechanism 200 and the purification effect of the air purification device.

[0042] In this embodiment, the protective component 100 includes an upper box body 101 and a lower box body 102. A plurality of arc grooves 103 are provided on the inner sides of the upper box body 101 and the lower box body 102. When the upper box body 101 and the lower box body 102 are buckled together, the two arc grooves 103 are positioned relative to each other and stably connected to the body of the hair dryer 210. The upper box body 101 and the lower box body 102 are provided with a hollow groove 104, and the power supply 110, the electrostatic generator 120, the water tank 130 and the control box 140 are all installed inside the hollow groove 104.

[0043] Specifically, during the installation process, first align the hair dryer 210 of the air cannon mechanism 200 with the arc groove 103, then buckle the upper box body 101 and the lower box body 102, and use screws to install the upper box body 101 and the lower box body 102. The arc groove 103 forms an adaptive clamping mechanism to tightly fix the hair dryer 210 to prevent it from shaking or displacement during the operation of the device, and can also effectively protect the air cannon mechanism 200, which not only ensures the normal operation of the air cannon mechanism 200, but also has a relatively simple installation method. When the air cannon mechanism 200 needs to be repaired or replaced, the operator can easily disassemble the protective component 100 and take out the air cannon mechanism 200 to perform corresponding operations.

[0044] It should be noted that the blower 210 of the wind gun mechanism 200 is not limited to the attached figure. Figure 1 The three single-row settings can also be an even-numbered multi-row setting.

[0045] The hollow groove 104 can provide installation space for the power supply 110, the electrostatic generator 120, the water tank 130 and the control box 140, while providing effective protection for the above components. In addition, the hollow groove 104 can ensure the structural strength of the protection component 100 while reducing the weight of the protection component 100, thereby achieving lightweighting of the device.

[0046] In this embodiment, a mounting portion 160 is installed at the bottom end of the lower box body 102, wherein the mounting portion 160 has a plurality of detachable universal wheels.

[0047] Specifically, when the device needs to be moved to different locations for air purification, such as in a construction site, different construction areas may have high dust, high smoke, and high haze pollution. The use of universal wheels can make the device easily move on the ground, ensuring the flexibility of the device. Since the mounting portion 160 adapted to this scenario adopts a detachable connection method, when the device is fixed at a specific location for long-term air purification, the universal wheels can be removed to place the device more stably on the ground;

[0048] The fixing ears 150 can be connected to corresponding fixing structures on the vehicle-mounted platform, so that the device can be moved with the vehicle to different working locations and remain stable during the driving of the vehicle.

[0049] In this embodiment, the air outlet end of the hair dryer 210 is also provided with an opening with an outer folded edge.

[0050] Specifically, when the axial flow fan 280 blows the purified air out of the hair dryer 210 , the opening of the outer fold edge can change the flow direction and speed distribution of the air, so that the air can be better purified by the negative ion emission module 270 .

[0051] In this embodiment, the electrostatic generator 120 is electrically connected to the negative ion emission module 270, the control box 140 is electrically connected to the electrostatic generator 120, a water pump is installed inside the water tank 130, the water pump is connected to the spray nozzle 290 through a pipeline, the power supply 110 is integrated with a control switch, and the power supply 110 is electrically connected to the electrostatic generator 120, the control box 140, the water pump and the axial fan 280 respectively through the control switch.

[0052] Specifically, the power supply 110 supplies power to the electrostatic generator 120, the control box 140, the water pump and the axial flow fan 280, and the above components can be controlled separately by the provided control switches.

[0053] Example 2

[0054] See also Figure 8-9The protective assembly 100 is a protective sleeve 105, and the protective sleeve 105 is fixedly covered on the outside of the air outlet 210. There are three or more air outlets 210, and the diameters of the three or more air outlets 210 can be the same or different. The air outlets 210 on both sides are rotatably connected to the air outlet 210 in the middle through the rotating shaft 106. The middle parts of the two rotating shafts are fixedly connected to the tops of the two supporting legs 107 through the shaft seat, and the bottoms of the two supporting legs 107 are fixedly connected to the bottom plate. At the top of 108, an installation box 1011 for placing a power supply 110, an electrostatic generator 120, a water tank 130 and a control box 140 is installed on the outer side of one of the supporting legs 107. The bottom of the base plate 108 is connected to the chassis of the all-terrain tracked vehicle 300 through the mounting portion 160 using an electric turntable 109. The bottom of the air outlet 210 located in the middle is connected to an electric telescopic rod 1010 through a hinged seat, and the bottom of the electric telescopic rod 1010 is fixedly connected to the top of the base plate 108.

[0055] Specifically, when the air purification device is started, the power supply 110 supplies power to the entire device, and the electrostatic generator 120, the axial flow fan 280, the water pump, the control box 140 and other components are started by the control switch. After the electrostatic generator 120 works, the high-voltage electrostatic adsorption net 220 generates an electrostatic field. The axial flow fan 280 rotates to form an air flow channel in the air outlet 210. When air containing high dust, high smoke, and high haze is sucked into the air outlet 210, the high-voltage electrostatic adsorption net 220 at the air inlet end adsorbs the charged tiny particles in the air under the action of the electrostatic field to achieve preliminary purification.

[0056] The structure of three or more air outlets 210, the middle air outlet 210 can adjust the angle through the electric telescopic rod 1010, when the electric telescopic rod 1010 is extended, it drives the middle air outlet 210 to rotate around the hinge seat, so as to change the air outlet direction, the air outlets 210 on both sides can rotate around the rotating shaft 106 relative to the middle air outlet 210, and further adjust the air outlet angle to meet the air purification needs in different directions; when the air is blown out from the air outlet 210, the negative ion emission module 270 starts to work under the control of the control box 140, and its discharge needle 271 releases negative ions, which combine with harmful gases such as sulfur dioxide and nitrogen oxides in the air, so that the harmful gases are precipitated or chemically reacted to be converted into harmless substances. At the same time, the water pump in the water tank 130 transports water to the spray nozzle 290 for spraying, and the water mist moistens the air, so that tiny particles gather and settle;

[0057] The chassis of the all-terrain tracked vehicle 300 is connected to the electric turntable 109 at the bottom of the base plate 108 through the mounting portion 160. The electric turntable 109 can drive the entire device to rotate, thereby adjusting the direction of purified air, so that the device can be moved to different positions on complex terrains (such as mines, building demolition sites, etc.), and can flexibly adjust the angle of the air outlet 210 and the overall orientation of the device to perform all-round air purification in high-dust, high-smoke, and high-haze spaces in different directions and at different heights, effectively remove pollutants, improve air quality, protect the health of workers and reduce damage to production equipment.

[0058] Example 3

[0059] See also Fig.10 , wherein the mounting frame 240 is a plurality of mounting rods 241 , and the negative ion emission module 270 is directly fixedly connected to one end of the mounting rod 241 .

[0060] Specifically, while ensuring that the negative ion emission module 270 cooperates with the discharge needle 271 to release negative ions that combine with harmful gases such as sulfur dioxide and nitrogen oxides in the air and various smoke and dust, so that the harmful gases are settled or the smoke and dust undergo chemical reactions and are converted into harmless substances, the installation structure of the negative ion emission module 270 is simplified, which can also reduce the overall manufacturing cost of the device to a certain extent.
