Description

Technical Field

[0001] This invention belongs to the field of air purification, specifically an air dust purification device. Background Technology

[0002] Air purification refers to the engineering discipline that removes pollutants such as particulate matter, harmful air, and bacteria from the air within a certain space, and controls indoor temperature, cleanliness, pressure, airflow speed and distribution, noise and vibration, lighting, and static electricity within a certain required range.

[0003] Dust in the air generally refers to larger particles that exist in the air. It is commonly found near construction sites, where dust is stirred up and mixed in with the air, as well as in factories, such as wood processing plants or powder production plants, where the dust content in the air is huge and specialized purification equipment is required.

[0004] The factory air contains a lot of dust, so high-power dust purification equipment is needed to purify the air. However, high-power purification equipment requires the air to pass through a large number of filters to gradually purify the particles in the air, resulting in a large overall size of the equipment. At the same time, a large negative pressure power is required to allow the air to circulate in the equipment, and frequent filter replacements are also required, which increases costs.

[0005] Therefore, the present invention provides an air dust purification device. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The air dust purification device of the present invention includes a water storage tank, a purification box is fixedly connected to the top of the water storage tank, a top cover is fixedly connected to the top of the purification box, two spiral tubes are connected to the middle of the purification box, a plurality of purification discs are connected to the middle of the spiral tubes, the purification discs use water mist to filter the passing air, the bottoms of the two spiral tubes are connected to each other through a connecting component, an air inlet pipe is connected to the top of one spiral tube, and an air outlet pipe is connected to the top of the other spiral tube. By using two spiral tubes, the air to be treated is sent into one of the spiral tubes through the air inlet duct. The purification discs in the spiral tube trap some of the particles in the air. As the air passes through the two spiral tubes, numerous purification discs use water mist to filter the particles layer by layer. The air discharged from the air outlet duct meets the emission standards. The entire device concentrates ventilation and filtration in two spiral tubes, eliminating the need for bulky purification channels. Furthermore, the purification discs and spiral tubes are connected as a single unit, requiring no disassembly or replacement of the internal structure. This integrated design greatly reduces the risk of air leakage after long-term use and also reduces the cost of frequent filter replacements.

[0008] Preferably, the purification disc has two through-type ends, and mesh plates are fixed to the inner walls of both ends of the purification disc. An atomizing nozzle is fixed to the top of the inner wall of the purification disc, and a water supply component is connected above the atomizing nozzle. The water supply component sprays atomized water into the atomizing nozzle, and the atomized water forms a dust-collecting space on the surface of the mesh plate and between the two mesh plates. The atomized water adsorbs particles in the air and finally gathers them into a stream on the surface of the spiral tube. Under the action of gravity, the stream flows downward and finally collects in the water tank. This not only effectively filters particles in the air, but also eliminates the need for filter cartridges. The mesh plates can be used for a long time without replacement, which saves costs and avoids frequent replacements.

[0009] Preferably, the water supply assembly includes two pressurized pipes, with a water supply valve connected between the tops of the two pressurized pipes. The water supply valve is located outside the purification box. The pressurized pipes are connected from top to bottom to atomizing nozzles in multiple purification trays in the same vertical column. Water is injected into the pressurized pipes through the water supply valve, and the water is transmitted from top to bottom to each atomizing nozzle, so that each atomizing nozzle receives the same water pressure, thus creating dust suppression areas of the same size.

[0010] Preferably, the connecting assembly includes a partition, with the bottoms of both spiral tubes located on one side of the partition. A sealing plate is fixed between the partition and the inner wall of the water tank. The bottom of the water tank contains clean water, and the level of the clean water is higher than the bottom of the partition. The partition and sealing plate allow the lower parts of the two spiral tubes to communicate with each other. At the same time, since the bottom of the partition is located between the water surfaces, the air in the two spiral tubes can communicate with each other, and the water with adsorbed particles in the spiral tubes can also flow into the water tank along the bottom of the spiral tubes.

[0011] Preferably, a recycling tank is fixed to the outer surface of the water storage tank, and a water pump is fixed to the top of the inner wall of the recycling tank. The output end of the water pump is connected to a water suction pipe, the bottom of which is located at the bottom of the water storage tank. A filter module is connected to the middle of the recycling tank, and a drain pump is connected to the bottom of the recycling tank. The output end of the drain pump is connected to the water supply valve. The cleaned water from the bottom of the water storage tank is drawn through the water suction pipe of the recycling tank, and the particles in the water are filtered through the filter module in the recycling tank. Then, the filtered water is sent to the water supply valve through the drain pump, thus forming a circulation system, which greatly reduces water waste. During high-power operation of the equipment, the circulation system can be shut off, and the internal water source can be drawn out using the water suction pipe, while the water supply valve continuously adds fresh water to meet the high-intensity use of the equipment.

[0012] Preferably, the inner side of the purification box is connected to two unblocking pipes, the bottom of which is open. Multiple guide pipes are fixed to the outer side of the unblocking pipes, and the guide pipes are connected to the outer bottom surface of the spiral tube. When the equipment is running at high intensity, there is a lot of atomized water, which can easily cause the water flow above the spiral tube to fall and form a blockage around the mesh plate. Moreover, the water that has filtered the particles can easily leave particles on the mesh plate after passing through many mesh plates. With the setting of the guide pipes, when the concentrated water flow flows from top to bottom, it will directly enter the unblocking pipe through the guide pipes and fall directly into the bottom of the water tank, allowing the water flow in the spiral tube to be discharged quickly without affecting the air circulation.

[0013] Preferably, a sealing sleeve is fixed to the outer wall of the spiral tube, and a float valve is slidably connected to the middle of the sealing sleeve. The float valve is located between the guide tube and the spiral tube. In order to prevent air from being directly discharged through the guide tube, the float valve is designed so that only when the water flow is large can the buoyancy of the water flow push the float valve up, allowing the sealing sleeve to flow. When there is no buoyancy, the float valve will be closed under the action of gravity.

[0014] Preferably, the float valve includes a float ball made of hollow plastic material. A hollow tube is fixed to the bottom of the float ball, and the bottom of the hollow tube is slidably connected to the middle of the sealing sleeve. A drain hole is provided on the outer surface of the hollow tube. When water flows through the float valve, the float ball will float up under the action of buoyancy, and the water will be discharged downward through the drain hole into the guide pipe. When the buoyancy disappears, the float ball and the hollow tube will merge with the sealing sleeve under the action of gravity and airflow.

[0015] Preferably, a submersible pipe is fixed to the bottom of the unclogging pipe, with the bottom of the submersible pipe located below the water surface. A liquid level monitoring module is connected to the water storage tank, which is used to control the liquid level between the bottom of the submersible pipe and the bottom of the spiral pipe. A water outlet pipe is connected between the bottom of the recovery tank and the water storage tank. The submersible pipe ensures that the bottom of the unclogging pipe is always below the water surface, keeping the unclogging pipe in a water pressure-sealed state. This further ensures that air in the spiral pipe will not be discharged from the bottom of the unclogging pipe. The liquid level monitoring module ensures that the liquid level is between the bottom of the submersible pipe and the bottom of the spiral pipe, allowing the device to operate smoothly. When the liquid level is low, water is replenished through the water outlet pipe.

[0016] Preferably, the bottom surface of the water storage tank is connected to an electric heating module. The diameters of the holes on the surface of the mesh plate are different, with the upper holes having smaller diameters and the lower holes having larger diameters. The water in the water storage tank is heated by the electric heating module, so that the final atomized liquid has a higher temperature, turning the airflow entering the device into a hot flow. This allows the gas to move along the upper inner wall of the spiral tube, while the liquid flows from the lower inner wall, without interfering with each other. The larger diameter holes at the bottom allow the liquid to pass through normally.

[0017] The beneficial effects of this invention are as follows: 1. The air dust purification device of the present invention uses two spiral tubes to send the air to be treated into one of the spiral tubes through an air inlet pipe. The purification discs in the spiral tubes will trap some of the particles in the air. As the air passes through the two spiral tubes, numerous purification discs use water mist to filter the particles in the air layer by layer. The air discharged from the air outlet pipe meets the emission standards. The entire device concentrates ventilation and filtration in two spiral tubes, eliminating the need for bulky purification channels. Moreover, the purification discs and spiral tubes are connected as a whole, eliminating the need for disassembly and replacement of internal structures. The integrated design greatly reduces the risk of air leakage after long-term use and also reduces the cost of frequent filter replacements.

[0018] 2. The air dust purification device of the present invention sprays atomized water into the atomizing nozzle through a water supply component. The atomized water forms a dust-reducing space on the surface of the mesh plate and between the two mesh plates, adsorbing particles in the air and finally agglomerating them on the surface of the spiral tube. Under the action of gravity, the particles flow downwards and finally collect in the water storage tank. This device can not only effectively filter particles in the air, but also eliminates the need for filter cartridges. The mesh plates can be used for a long time without replacement, which saves costs and eliminates the need for frequent replacements. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 4 As shown in the figure, an air dust purification device according to an embodiment of the present invention includes a water storage tank 1, a purification box 2 fixedly connected to the top of the water storage tank 1, a top cover 3 fixedly connected to the top of the purification box 2, two spiral tubes 11 connected to the middle of the purification box 2, and multiple purification discs 13 connected to the middle of the spiral tubes 11. The purification discs 13 use water mist to filter the passing air. The bottoms of the two spiral tubes 11 are connected to each other through a connecting component. The top of one spiral tube 11 is connected to an air inlet pipe 7, and the top of the other spiral tube 11 is connected to an air outlet pipe 8. During operation, the factory air contains a lot of dust, requiring the use of high-power dust purification equipment to purify the air. However, high-power purification equipment requires the air to pass through a large number of filters to gradually purify the particles in the air, resulting in a large overall size of the equipment. At the same time, it also requires a large negative pressure power to allow the air to circulate in the equipment, and frequent filter replacements are also required, leading to increased costs. By using two spiral tubes 11, the air to be treated is sent into one of the spiral tubes 11 through the air inlet duct 7. The purification discs 13 in the spiral tube 11 will trap some of the particles in the air. As the air passes through the two spiral tubes 11, the numerous purification discs 13 use water mist to filter the particles in the air layer by layer. The air discharged from the air outlet duct 8 meets the emission standards. The entire device concentrates ventilation and filtration in the two spiral tubes 11, eliminating the need for bulky purification channels. Moreover, the purification discs 13 and the spiral tubes 11 are connected as a whole, eliminating the need for disassembly and replacement of the internal structure. The integrated design greatly reduces the risk of air leakage after long-term use and also reduces the cost of frequent filter replacements.

[0023] like Figures 2 to 7 As shown, the two ends of the purification plate 13 are connected through each other. Mesh plates 20 are fixed to the inner walls of both ends of the purification plate 13. An atomizing nozzle 21 is fixed to the top of the inner wall of the purification plate 13. A water supply component for water supply is connected above the atomizing nozzle 21. During operation, atomized water is sprayed into the atomizing nozzle 21 through the water supply component. The atomized water forms a dust-collecting space between the two mesh plates 20, adsorbing particles in the air and finally converging them into a stream on the surface of the spiral tube 11. Under the action of gravity, the stream flows downward and finally collects in the water storage tank 1. This not only effectively filters particles in the air, but also eliminates the need for filter cartridges. The mesh plates 20 can be used for a long time without replacement, saving costs and eliminating the need for frequent replacements.

[0024] like Figures 1 to 7 As shown, the water supply assembly includes two pressurizing pipes 12, and a water supply valve 4 is connected between the tops of the two pressurizing pipes 12. The water supply valve 4 is located outside the purification tank 2. The pressurizing pipes 12 are connected from top to bottom to the atomizing nozzles 21 in the multiple purification discs 13 in the same vertical column. During operation, water is injected into the pressurization pipe 12 through the water supply valve 4. The water is then transmitted from top to bottom to each atomizing nozzle 21 through the pressurization pipe 12. Since the multiple purification discs 13 are close together, the water pressure on each atomizing nozzle 21 is roughly the same, which can form a dust suppression area of ​​the same size.

[0025] like Figures 1 to 4 As shown, the connecting assembly includes a partition 15, the bottom of which does not contact the inner bottom wall of the water storage tank 1, the bottoms of the two spiral tubes 11 are located on one side of the partition 15, a sealing plate 14 is fixed between the partition 15 and the inner wall of the water storage tank 1, the bottom of the water storage tank 1 contains clean water, the liquid level of the clean water is higher than the bottom surface of the partition 15, and the lower pipe openings of the two spiral tubes 11 are higher than the liquid level of the clean water. During operation, the partition 15 and the sealing plate 14 allow the lower parts of the two spiral tubes 11 to be connected. Since the bottom of the partition 15 is below the water surface, the air in the two spiral tubes 11 can be connected. At the same time, the water that has adsorbed particles in the spiral tubes 11 can also flow into the water storage tank 1 along the bottom of the spiral tubes 11.

[0026] like Figures 1 to 4 As shown, a recycling tank 5 is fixed to the outer surface of the water storage tank 1, a water suction pump is fixed to the top of the inner wall of the recycling tank 5, the output end of the water suction pump is connected to a water pumping pipe 6, the bottom of the water pumping pipe 6 is located at the bottom of the water storage tank 1, a filter module is connected to the middle of the recycling tank 5, a drain pump is connected to the bottom of the recycling tank 5, and the output end of the drain pump is connected to the water supply valve 4. During operation, the cleaned water from the bottom of the water storage tank 1 is drawn through the water pump 6 of the recycling tank 5. The water passes through the filter module in the recycling tank 5 to filter out particles. Then, the filtered water is sent to the water supply valve 4 through the drain pump, thus forming a circulation system and greatly reducing water waste. During high-power operation of the equipment, the circulation system can be shut off, the water pump 6 is used to draw out the internal water, and the water supply valve 4 continuously adds fresh water to meet the high-intensity use of the equipment.

[0027] like Figures 1 to 4 As shown, the inner side of the purification box 2 is connected to two unblocking pipes 9. The bottom of the unblocking pipe 9 is open. Multiple guide pipes 17 are fixed to the outer side of the unblocking pipe 9. The guide pipes 17 are connected to the outer bottom surface of the spiral pipe 11. When the equipment is running at high intensity, there is a lot of atomized water, which can easily cause blockage around the mesh plate 20 when the water flow above the spiral tube 11 drops. In addition, the water that has filtered the particles increases the probability of particles being left on the mesh plate 20 as it passes through many mesh plates 20. With the setting of the guide pipe 17, when the concentrated water flow flows from top to bottom, it will directly enter the unblocking pipe 9 through the guide pipe 17 and fall directly into the bottom of the water storage tank 1, so that the water flow in the spiral tube 11 can be discharged quickly without affecting the air circulation.

[0028] like Figures 4 to 5 As shown, a sealing sleeve 18 is fixedly connected to the outer wall of the spiral tube 11, and a float valve 19 is slidably connected to the middle of the sealing sleeve 18. The float valve 19 is located between the guide tube 17 and the spiral tube 11. During operation, in order to prevent air from being directly discharged through the guide pipe 17, the float valve 19 is designed so that only when the water flow is large can the buoyancy of the water flow push the float valve 19 up, allowing the sealing sleeve 18 to flow. When there is no buoyancy, the float valve 19 will be closed under the action of gravity.

[0029] like Figures 4 to 5As shown, the float valve 19 includes a float ball, which is made of hollow plastic material. A hollow tube is fixed to the bottom of the float ball. The bottom of the hollow tube is slidably connected to the middle of the sealing sleeve 18. A drain hole is provided on the outer surface of the hollow tube. When the water flows through the float valve 19, the float will rise under the action of buoyancy, and the water will be discharged downward through the drain hole and discharged into the guide pipe 17. When the buoyancy disappears, the float will move downward under the action of gravity to block the sealing sleeve 18.

[0030] like Figures 3 to 4 As shown, a submersible pipe 16 is fixed to the bottom of the unblocking pipe 9. The bottom of the submersible pipe 16 is located below the water surface. A liquid level monitoring module is connected to the water storage tank 1. The liquid level monitoring module is used to control the liquid level between the bottom of the submersible pipe 16 and the bottom of the spiral pipe 11. A water outlet pipe 10 is connected between the bottom of the recycling box 5 and the water storage tank 1. During operation, the submersible pipe 16 ensures that the bottom of the unblocking pipe 9 is always below the water surface, keeping the unblocking pipe 9 in a water pressure-sealed state. This further ensures that the air in the spiral pipe 11 will not be discharged from the bottom of the unblocking pipe 9. The liquid level monitoring module ensures that the liquid level is between the bottom of the submersible pipe 16 and the bottom of the spiral pipe 11, allowing the device to operate smoothly. When the liquid level is low, water is replenished through the outlet pipe 10.

[0031] like Figures 3 to 6 As shown, an electric heating module is connected to the bottom surface of the water storage tank 1, and the diameter of the holes on the surface of the mesh plate 20 is different. The holes at the top have a smaller diameter, and the holes at the bottom have a larger diameter. During operation, the water in the water storage tank 1 is heated by the electric heating module, so that the final atomized liquid has a high temperature, which turns the airflow entering the equipment into a hot flow. This allows the gas to move along the upper inner wall of the spiral tube 11, while the liquid flows from the lower inner wall, without interfering with each other. The larger diameter hole at the bottom allows the liquid to pass through normally.

[0032] During operation, the air to be processed is sent into one of the spiral tubes 11 through the air inlet pipe 7 via the two spiral tubes 11. The purification discs 13 in the spiral tube 11 will trap some of the particles in the air. As the air passes through the two spiral tubes 11, the numerous purification discs 13 use water mist to filter the particles in the air layer by layer. The air discharged from the air outlet pipe 8 meets the emission standards. The entire device concentrates ventilation and filtration in the two spiral tubes 11, eliminating the need for bulky purification channels. Moreover, the purification discs 13 and the spiral tubes 11 are connected as a whole, eliminating the need for disassembly and replacement of the internal structure. The integrated design greatly reduces the risk of air leakage after long-term use and also reduces the cost of frequent filter replacement. Atomized water is sprayed into the atomizing nozzle 21 through the water supply component. The atomized water forms a dust-collecting space on the surface of the mesh plate 20 and between the two mesh plates 20. It adsorbs the particles in the air and finally gathers them into a stream on the surface of the spiral tube 11. Under the action of gravity, the stream flows downward and finally collects in the water storage tank 1. It can not only effectively filter the particles in the air, but also eliminates the need for filter cartridges. The mesh plates 20 can be used for a long time without replacement, which saves costs and eliminates the need for frequent replacement. Water is injected into the pressurization pipe 12 through the water supply valve 4. The water is then transmitted from top to bottom to each atomizing nozzle 21 through the pressurization pipe 12, so that each atomizing nozzle 21 is subjected to the same water pressure, thus creating dust suppression areas of the same size. The partition 15 and the sealing plate 14 allow the lower parts of the two spiral tubes 11 to be connected to each other. At the same time, since the bottom of the partition 15 is located between the water surface, the air in the two spiral tubes 11 can be connected to each other. Meanwhile, the water that has adsorbed particles in the spiral tubes 11 can also flow into the water storage tank 1 along the bottom of the spiral tubes 11. Water cleaned from the bottom of water tank 1 is drawn through the water pipe 6 of recycling tank 5. The water passes through the filter module in recycling tank 5 to filter out particles. Then, the filtered water is sent to water supply valve 4 through the drain pump, thus forming a circulation system and greatly reducing water waste. During high-power operation of the equipment, the circulation system can be shut off, the water pipe 6 can be used to draw out the internal water, and the water supply valve 4 can continuously add fresh water to meet the high-intensity use of the equipment. When the equipment is running at high intensity, there is a lot of atomized water, which can easily cause the water flow above the spiral tube 11 to fall and form a blockage around the mesh plate 20. In addition, the water that has filtered the particles can easily leave particles on the mesh plate 20 after passing through many mesh plates 20. With the setting of the guide pipe 17, when the concentrated water flow flows from top to bottom, it will directly enter the unblocking pipe 9 through the guide pipe 17 and fall directly into the bottom of the water storage tank 1, so that the water flow in the spiral tube 11 can be discharged quickly without affecting the air circulation. To prevent air from being directly discharged through the guide pipe 17, the float valve 19 is designed so that only when the water flow is large can the buoyancy of the water flow push the float valve 19 up, allowing the sealing sleeve 18 to flow. When there is no buoyancy, the float valve 19 will be closed under the action of gravity. When water flows through the float valve 19, the float will rise under the action of buoyancy, and the water will be discharged downward through the drain hole and discharged into the guide pipe 17. When the buoyancy disappears, the float and the hollow pipe will merge with the sealing sleeve 18 under the action of gravity airflow. The submersible pipe 16 ensures that the bottom of the unblocking pipe 9 is always below the water surface, keeping the unblocking pipe 9 in a water pressure-sealed state. This further ensures that air in the spiral pipe 11 will not enter the guide pipe 17. The liquid level monitoring module ensures that the liquid level is between the bottom of the submersible pipe 16 and the bottom of the spiral pipe 11, allowing the device to operate smoothly. When the liquid level is low, water is replenished through the outlet pipe 10. The water in the water storage tank 1 is heated by the electric heating module, so that the final atomized liquid has a high temperature, which turns the airflow entering the equipment into a hot flow. This allows the gas to move along the upper inner wall of the spiral tube 11, while the liquid flows from the lower inner wall, without interfering with each other. The larger diameter hole at the bottom allows the liquid to pass through normally.
