[0002] With rapid industrial development and an increase in various engineering projects, air pollution has become an increasingly prominent problem.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] First, let's introduce the existing fog cannons.

[0029] As the core component of a fogging machine, the guide jet tube's main function is to atomize fluid and spray it onto the polluted area to cover and treat pollutants. However, if only water is sprayed, it can only remove some large dust particles through physical sedimentation. It cannot effectively treat acidic harmful gases such as sulfides and nitrogen oxides in industrial waste gas, as well as fine PM2.5 dust, making it difficult to achieve the ideal air pollution control effect. Therefore, in order to fully utilize the treatment efficiency of the guide jet tube, setting up a chemical dosing structure in the fogging machine and adding chemicals to the atomized fluid has become a key means to solve the above-mentioned core problems.

[0030] A creative discovery reveals that while some mist sprayers have attempted to incorporate chemical dosing functions, traditional dosing methods often involve direct powder addition or liquid addition. Powder addition easily generates dust, polluting the operating environment, harming operators' health, and wasting chemicals. Furthermore, powder dissolves slowly and mixes unevenly with water, leading to fluctuations in the atomized liquid concentration and affecting treatment effectiveness. Additionally, fine powder particles can clog pipes and nozzles, increasing equipment maintenance costs. Liquid addition requires pre-preparation, is cumbersome, and the liquid has poor stability, is volatile, and easily becomes ineffective over long-term storage, compatibility issues are also present. In contrast, using the form of chemical blocks for dosing can effectively solve all the above-mentioned drawbacks and has outstanding application advantages: First, the chemical blocks have a regular shape and strong stability, and there is no dust flying during dosing, which is both environmentally friendly and avoids waste of chemicals, while also protecting the health of operators; Second, the chemical blocks can achieve slow-release dissolution, without the need for pre-preparation, making operation convenient, and can continuously and stably release the effective components of the chemicals, ensuring uniform concentration of the atomized liquid and greatly improving the pollution control effect; Third, the dense structure of the chemical blocks makes it difficult to generate fine particles, which can effectively avoid clogging of pipelines and nozzles and reduce equipment maintenance costs.

[0031] Based on the above-mentioned inventive discovery, this application provides a fogging device for air pollution control with good performance. By using a drug block for slow-release dosing and combining it with an oscillating component, the guide jet tube can oscillate back and forth during the spraying process, further expanding the coverage of atomized droplets, and taking into account the treatment effect, ease of operation and practicality of the equipment.

[0032] The following is a description of the fog cannon provided in this application.

[0033] like Figure 1 and Figure 2 As shown, a fogging device for air pollution control with good performance is disclosed. The fogging device includes a movable base 1, a guide jet tube 103, a high-pressure atomizing pump 104, a dosing component, and an oscillating component. The dosing component is connected to the input end of the high-pressure atomizing pump 104 through a water inlet pipe 2. The oscillating component is linked with the dosing component and is drivenly connected to the guide jet tube 103. The dosing component uses a drug block for slow-release dosing, and the oscillating component realizes reciprocating oscillation to expand the coverage range of the atomized droplets.

[0034] Furthermore, the base 101 is fixedly installed on the top of the movable base 1, and the high-pressure atomizing pump 104 is fixedly installed on one side of the top of the base 101. The high-pressure atomizing pump 104 is connected to the guide jet tube 103 through a hose to provide pressurization power for the atomized liquid and realize atomization spray. The base 101 is fixedly connected to the top of the movable base 1, and the water inlet pipe 2 is sealed to the input end of the high-pressure atomizing pump 104 through a rotary joint. The high-pressure atomizing pump 104 provides the high-pressure power required for atomization. The rotary joint can prevent the water inlet pipe 2 from twisting or breaking as the equipment linkage parts rotate, ensuring the stability of water flow delivery.

[0035] like Figure 2 , Figure 6 and Figure 7 As shown, in one embodiment, the dosing assembly includes a slow-release dosing cartridge 201, a limiting filter plate 202, and a dosing tube 203. The slow-release dosing cartridge 201 is fixedly disposed on one side of the top of the movable seat 1. There are two limiting filter plates 202, which are fixedly embedded in the inner wall of the slow-release dosing cartridge 201. The water kinetic energy generated by the high-pressure atomizing pump 104 drives the dosing assembly to complete the slow-release dosing and mixing, and drives the swing assembly to swing the guide jet tube 103. The two limiting filter plates 202 realize the limiting constraint of the drug block, preventing the drug block from violently rolling and colliding with the inner wall of the slow-release dosing cartridge 201 and breaking, while not affecting the full contact between the water flow and the drug block.

[0036] Specifically, the dosing assembly also includes a blade shaft 204, multiple mixing rods 205, two scrapers 206, turbine blades 207, and a connecting pipe 208; one end of the slow-release cartridge 201 is connected to the connecting pipe 208, and the other end of the slow-release cartridge 201 is connected to the inlet pipe 2; the dosing pipe 203 is installed on the outer surface of the slow-release cartridge 201, and a cap is provided on one side of the dosing pipe 203; the blade shaft 204 is connected to two limiting filter plates 202 via bearings; by opening the cap on the dosing pipe 203, the corresponding type of chemical can be added into the slow-release cartridge 201. The impact force of the water flow drives the turbine blades 207 to rotate at high speed. Since the turbine blades 207 are fixedly connected to the blade shaft 204, the rotation of the turbine blades 207 will synchronously drive the blade shaft 204 to rotate. When the blade shaft 204 rotates, it will synchronously drive the multiple mixing rods 205 and two scrapers 206 fixed on its outer surface to rotate together. When the multiple mixing rods 205 rotate, they will fully stir the water and drug block in the slow-release cartridge 201, accelerate the dissolution rate of the drug block, and make the effective ingredients of the drug block after dissolution evenly mixed with water to form a stable concentration of atomized liquid.

[0037] Specifically, turbine blades 207 are fixedly installed on one end of blade shaft 204 near the water inlet pipe 2. Multiple mixing rods 205 and two scrapers 206 are fixedly installed on the outer surface of blade shaft 204. Both scrapers 206 are arc-shaped, and the arc surfaces of the two scrapers 206 are in contact with the inner wall of the slow-release cartridge 201. The rotation of the mixing rods 205 can also break the static state of the water flow, prevent the effective ingredients after the drug block dissolves from settling, and ensure uniform concentration of the atomized liquid. When the two scrapers 206 rotate synchronously, their arc surfaces will continuously scrape the inner wall of the slow-release cartridge 201, which can remove the drug block dissolution residue attached to the inner wall of the slow-release cartridge 201.

[0038] It should be noted that, depending on the actual needs of the pollution control environment on site, corresponding types of drug blocks can be added into the slow-release drug cartridge 201. Bentonite adsorption slow-release columnar agents are suitable for scenarios with high dust concentrations and large amounts of PM2.5, such as construction sites, mines, and sand and gravel pits. Composite flocculant slow-release porous blocks are suitable for scenarios where industrial dust, construction dust, and other dust particles need to be quickly agglomerated, such as steel plants, cement plants, and construction sites. Quicklime alkaline neutralization solid blocks are suitable for scenarios where acidic gaseous pollutants containing sulfides and nitrogen oxides are treated, such as chemical plants, smelters, and waste incineration sites.

[0039] like Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 8 As shown, in one embodiment, the oscillating assembly includes a piston 401, a guide tube 402, a rotating rod 403, an eccentric drive cam 404, a connecting rod 405, a sealing box 406, a first bevel gear 407, and a second bevel gear 408. The sealing box 406 is installed on the inner wall of the sustained-release cartridge 201. The first bevel gear 407 and the second bevel gear 408 are both installed inside the sealing box 406, and the first bevel gear 407 and the second bevel gear 408 mesh and drive each other. When the blade shaft 204 rotates, it will synchronously drive the first bevel gear 407 to rotate, which in turn drives the second bevel gear 408 to rotate. Since the first bevel gear 407 and the second bevel gear 408 are inside the sealing box 406, the sealing box 406 can effectively isolate the atomizing liquid.

[0040] Specifically, the first bevel gear 407 is fixedly connected to the end of the blade shaft 204 away from the turbine blade 207, one end of the rotating rod 403 is fixedly connected to the second bevel gear 408, and the eccentric drive cam 404 is fixedly installed on the other end of the rotating rod 403.

[0041] Specifically, piston 401 is movably embedded in the inner wall of piston cylinder 4, one end of connecting rod 405 is hinged to piston 401, and the other end of connecting rod 405 is hinged to one side of eccentric drive cam 404. Rotary rod 403 and blade shaft 204 are both connected to one side of sealing box 406 through bearings. A protective frame 409 is fixedly installed on one side of moving seat 1, and connecting rod 405 is located inside the protective frame 409. A support rod 3 is fixedly installed at the bottom of mounting bracket 102, and the support rod 3 is connected to the swing assembly in a transmission manner.

[0042] Furthermore, the swing assembly also includes a rack 307, a spur gear 301, and a hollow cylinder 302; the spur gear 301 is fixedly sleeved on the outer surface of the support rod 3, the rack 307 meshes with the spur gear 301 for transmission, and the hollow cylinder 302 is fixedly disposed on one side of the inner wall of the base 101.

[0043] Furthermore, the swing assembly also includes a push plate 303, a round rod 304, a connecting plate 305, and a spring 306; one end of the round rod 304 is fixedly disposed on one side of the connecting plate 305, and the other end is fixedly disposed on one side of the push plate 303, with the push plate 303 slidably embedded in the inner wall of the hollow cylinder 302; the spring 306 is movably sleeved on the outer surface of the round rod 304, with both ends of the spring 306 abutting against one side of the push plate 303 and the inner wall of the hollow cylinder 302, respectively; the rack 307 is fixedly connected to the connecting plate 305; and the push plate 306... Plate 303 drives connecting plate 305 to move synchronously via round rod 304. Connecting plate 305 is fixedly connected to rack 307, thereby driving rack 307 to move forward. The forward movement of rack 307 will drive spur gear 301 to rotate around support rod 3, thereby driving support rod 3 to rotate. When push plate 303 is pushed forward by high-pressure gas, spring 306 is compressed and stored energy. When the gas pressure disappears, spring 306 releases stored energy, pushing push plate 303 to reset, thereby driving rack 307 to move in the opposite direction, realizing the reciprocating swing of guide jet tube 103.

[0044] Furthermore, a control valve is installed on the guide pipe 402 to control the swing and stop of the guide jet tube 103. One end of the guide pipe 402 is installed on one side of the hollow cylinder 302 to deliver gas into the hollow cylinder 302 to drive the push plate 303 to move. By controlling the opening and closing of the control valve, the working state of the guide jet tube 103 can be flexibly adjusted to meet the needs of different pollution control scenarios.

[0045] The fogging device of this invention utilizes the kinetic energy of water generated by the high-pressure atomizing pump 104 to achieve slow-release drug mixing and the oscillation function of the guide jet tube 103. It requires no additional power source, is adaptable to various pollution control scenarios, is easy to operate, and boasts high purification efficiency. The specific working principle is as follows: Before use, the device can be moved to the designated pollution treatment location via the mobile seat 1 to fix its position. Open the cap on the dosing pipe 203 and add the corresponding type of drug block into the slow-release dosing cartridge 201 according to the actual pollution treatment environment requirements. The added drug block is placed between the two limiting filter plates 202. The two limiting filter plates 202 limit and constrain the drug block to prevent it from rolling violently with the water flow and colliding with the inner wall of the slow-release dosing cartridge 201 and breaking. At the same time, it does not affect the full contact between the water flow and the drug block. After the drug block is added, connect the connecting pipe 208 to the external water supply pipeline. During spraying, the high-pressure atomizing pump 104 is started and its control switch is turned on. External water enters the slow-release cartridge 201 through the connecting pipe 208, making initial contact with the medicine block inside. After the high-pressure atomizing pump 104 starts, a negative pressure suction is generated through the inlet pipe 2, drawing water from the slow-release cartridge 201 into the high-pressure atomizing pump 104. One end of the inlet pipe 2 is sealed to the input end of the high-pressure atomizing pump 104 via a rotary joint. The rotary joint prevents the inlet pipe 2 from twisting or breaking due to the rotation of the equipment's linkage components, ensuring the stability of the water flow. As the water flows through the inlet pipe 2 into the high-pressure atomizing pump 104, it passes through the turbine blades 207 inside the inlet pipe 2. The impact force of the water flow drives the turbine blades 207 to rotate at high speed. The turbine blades 207 are fixedly connected to the blade shaft 204. The rotation of the turbine blades 207 will synchronously drive the blade shaft 204 to rotate. When the blade shaft 204 rotates, it will synchronously drive the multiple mixing rods 205 and the two scrapers 206 fixed on its outer surface to rotate together. When the multiple mixing rods 205 rotate, they will fully stir the water and drug block in the slow-release cartridge 201, accelerate the dissolution rate of the drug block, and make the effective ingredients after the drug block dissolves evenly mixed with the water to form a stable concentration of atomized liquid. At the same time, the rotation of the mixing rods 205 can also break the static state of the water flow, prevent the effective ingredients after the drug block dissolves from settling, and ensure the uniform concentration of the atomized liquid. When the two scrapers 206 rotate synchronously, their arc-shaped surfaces will continuously scrape the inner wall of the slow-release cartridge 201, which can scrape off the drug block dissolution residue attached to the inner wall of the slow-release cartridge 201 and prevent residual scale from clogging the pipeline. Through the synergistic action of the mixing rod 205 and the scraper 206, the water and the drug block in the slow-release cartridge 201 are fully mixed to form a uniform atomized liquid. The atomized liquid is continuously drawn into the high-pressure atomizing pump 104 through the water inlet pipe 2 and pressurized by the high-pressure atomizing pump 104. As the blade shaft 204 rotates, it synchronously drives the first bevel gear 407 to rotate, which in turn drives the second bevel gear 408 to rotate. Since the first bevel gear 407 and the second bevel gear 408 are located inside the sealed box 406, the sealed box 406 can effectively isolate the atomizing liquid and prevent moisture from entering and affecting the gear transmission efficiency. When the second bevel gear 408 rotates, it synchronously drives the rotating rod 403 to rotate. The rotation of the rotating rod 403 will drive the eccentric drive cam 404 to perform eccentric rotation. The eccentric drive cam 404 is connected to the piston 401 through the connecting rod 405. The eccentric rotation of the eccentric drive cam 404... The rotary motion is converted into the reciprocating linear motion of the piston 401 inside the piston cylinder 4 via the connecting rod 405. When the piston 401 reciprocates inside the piston cylinder 4, its motion is divided into two stages, corresponding to the oscillating motion of the guide jet tube 103. In the first stage, when the piston 401 moves towards the inner wall of the piston cylinder 4, it compresses the gas inside the piston cylinder 4. The compressed high-pressure gas is transported to the hollow cylinder 302 through the guide pipe 402. The high-pressure gas pushes the push plate 303 inside the hollow cylinder 302 forward. The push plate 303 drives the connecting plate 305 forward synchronously via the round rod 304. 05 is fixedly connected to rack 307, which in turn drives rack 307 to move forward. The forward movement of rack 307 will drive spur gear 301 to rotate around support rod 3, which in turn drives support rod 3 to rotate. The rotation of support rod 3 will cause mounting bracket 102 and guide jet tube 103 mounted on mounting bracket 102 to swing to one side. In the second stage, when piston 401 moves to the side of piston cylinder 4 closer to connecting rod 405, gas compression is no longer generated inside piston cylinder 4. At this time, spring 306 inside hollow cylinder 302 releases stored energy. Spring 306 pushes push plate 303 to return to its original position. Push plate 303 passes through round rod 3 04. The connecting plate 305 drives the rack 307 to move backward, and the rack 307 drives the spur gear 301 to rotate in the opposite direction, thereby driving the support rod 3, the mounting bracket 102 and the guide jet tube 103 to swing to the other side. A control valve is installed on the guide pipe 402. When the guide jet tube 103 does not need to swing, the control valve is opened, and the compressed gas inside the piston cylinder 4 can be discharged through the valve and cannot enter the hollow cylinder 302. The push plate 303 cannot move, thereby keeping the guide jet tube 103 at a fixed angle, realizing the controllable adjustment of swing and stop, and adapting to the pollution control needs of different coverage areas. The high-pressure atomizing pump 104 pressurizes the atomizing liquid it draws in and delivers it to the inside of the guide jet tube 103 through a hose. Under high pressure, the atomizing liquid is atomized through the nozzle of the guide jet tube 103 to form droplets. At the same time, the guide jet tube 103 oscillates back and forth or maintains a fixed angle to evenly spray the atomized droplets onto the polluted area. The droplets come into contact with pollutants in the air and, through physical adsorption, collision coagulation, or chemical neutralization reactions, achieve the removal and sedimentation of pollutants, thereby achieving the purpose of air pollution prevention and control.

[0046] In summary, during the entire operation of the fogging device of the present invention, the water kinetic energy generated by the high-pressure atomizing pump 104 is used to synchronously drive the turbine blades 207 to rotate, thereby realizing the slow-release dissolution of the drug block and the mixing of the atomized liquid, as well as the reciprocating oscillation function of the guide jet tube. There is no additional power source, and the structure is compact and has a low failure rate.
