Description

Technical Field

[0001] This utility model belongs to the field of odor treatment technology, specifically relating to a micro-nano hydroxyl odor purification device. Background Technology

[0002] Micro-nano hydroxyl odor purification devices are a type of high-efficiency gas purification equipment widely used in the industrial field. They work by pressurizing a specific deodorizing liquid with a high-pressure pump and then atomizing it into tiny particles through nozzles to form a mist spray. This mist spray allows the odor molecules in the air to fully contact and react, thus achieving the effect of removing odors.

[0003] Utility model patent CN212855249U discloses an odor elimination device for a spray treatment tower. This odor elimination device has several nano-microbubble generators installed above a turbulence device. The nano-microbubble generators spray nano-sized microbubbles in the air intake direction. Metal plates are also installed on the inner wall of the tower, positioned below the nano-microbubble generators. This utility model can eliminate both negatively charged and positively charged odor molecules, while also utilizing the odor-eliminating function of metal ions themselves, achieving the goal of eliminating air odors as much as possible.

[0004] However, in the aforementioned patent, if the original space size of the device is maintained, the exhaust gas can only be purified once by the nano bubble generator, resulting in incomplete purification and the gas delivered to the next stage not meeting the standards. If more nano bubble generators are to be installed, the space required is large, which will result in the equipment occupying too much area. Utility Model Content

[0005] The purpose of this invention is to provide a micro / nano hydroxyl odor purification device to solve the problems mentioned in the background art.

[0006] To achieve the above-mentioned technical objectives, the technical solution of this utility model is as follows:

[0007] A micro / nano hydroxyl odor purification device includes a water tank, a reaction chamber mounted on top of the water tank, and the water tank and the reaction chamber connected. The water tank has an air inlet on its side wall, and the reaction chamber has an air outlet on its top. An air outlet pipe, spiral in shape, is installed inside both the water tank and the reaction chamber. Both ends of the air outlet pipe are connected to the air inlet and the air outlet, respectively, and are fixedly connected to both ends. A water inlet pipe, also spiral in shape, is installed inside the water tank and the reaction chamber. The upper end of the water inlet pipe is open, penetrating through and fixedly connected to the side wall of the reaction chamber, while the lower end is closed. The water inlet pipe is installed in conjunction with the air outlet pipe. Several nano-microbubble generators are evenly mounted on the water inlet pipe, and the output ends of the nano-microbubble generators are connected to the air outlet pipe. A water supply mechanism is connected to the water inlet pipe. A drainage mechanism is installed at the bottom of the air outlet pipe.

[0008] As an improvement, the drainage mechanism includes a drain pipe that is connected to the bottom of the vent pipe and is fixedly connected to the bottom of the vent pipe. A U-shaped pipe is installed at the bottom of the drain pipe.

[0009] As an improvement, the upper part of the outer wall of the water tank is provided with a water inlet, and the lower part of the outer wall of the water tank is provided with a drain outlet. Both the water inlet and the drain outlet are equipped with control valves.

[0010] As an improvement, the water supply mechanism includes a water outlet pipe, which is fixedly connected to the lower part of the side wall of the water tank and penetrates through the side wall of the water tank. The water outlet pipe is connected to a water pump, which is connected to a water inlet pipe, and the water inlet pipe is connected to the water inlet pipe.

[0011] As an improvement, a filter is installed at one end of the water outlet pipe inside the water tank.

[0012] As an improvement, the air outlet is equipped with a fan, and the fan is connected to an air supply pipe.

[0013] As an improvement, the top of the water tank is provided with a water tank hole.

[0014] Due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows:

[0015] The micro-nano hydroxyl odor purification device provided by this utility model involves pressurizing clean water through a high-pressure pump and then introducing it into a micro-nano bubble generator. Within the micro-nano bubble generator, a large number of micro-nano bubbles are generated in the clean water. Because these micro-nano bubbles carry a large number of negative charges, they can quickly capture odor molecules with positive charges. At the moment the bubbles annihilate, the odor molecules are decomposed under high temperature and high pressure. The large number of hydroxyl free radicals generated during annihilation can rapidly oxidize the odor-causing groups, thereby achieving the purpose of purifying odorous waste gas.

[0016] By setting a spiral air intake pipe, the length of the gas passage is increased, and multiple nano-microbubble generators are set along the air intake pipe, which can purify the exhaust gas multiple times, resulting in better purification effect and smaller footprint.

[0017] A drain pipe and a U-shaped pipe are installed at the bottom of the vent pipe. The U-shaped pipe initially contains water, which can block the gas from passing through. This prevents the gas from the vent pipe from entering the water tank through the U-shaped pipe and being discharged directly from the water tank hole to the outside of the device without purification, thus polluting the surrounding environment. When the water in the U-shaped pipe reaches the height of the U-shaped pipe, the water flowing down from the vent pipe can be discharged into the water tank from the end away from the drain pipe.

[0023] like Figure 1 , 2 As shown, a micro-nano hydroxyl odor purification device includes a water tank 5, a reaction chamber 3 installed on the top of the water tank 5, the water tank 5 and the reaction chamber 3 are connected, the side wall of the water tank 5 is provided with an air inlet 4, and the top of the reaction chamber 3 is provided with an air outlet 1; the odorous exhaust gas can enter the device from the air inlet 4 and be discharged to the outside of the device from the air outlet 1.

[0024] A vent pipe 15 is installed inside the water tank 5 and the reaction tank 3. The vent pipe 15 is spiral-shaped. The spiral design can increase the length of the vent pipe 15 without taking up too much space. The two ends of the vent pipe 15 are connected to the air inlet 4 and the air outlet 1, respectively. Valves are installed at both the air inlet 4 and the air outlet 1 to control the entry speed of the exhaust gas. The two ends of the vent pipe 15 are fixedly connected to the air inlet 4 and the air outlet 1, respectively. The two ends of the vent pipe 15 are fixedly connected to the air inlet 4 and the air outlet 1, respectively, through a flange structure. The odorous exhaust gas enters from the air inlet 4, passes through the vent pipe 15, and is discharged to the outside of the device from the air outlet 1.

[0025] Water inlet pipes 14 are installed inside water tank 5 and reaction chamber 3. Water inlet pipe 14 is spiral-shaped, with its upper end open and penetrating the side wall of reaction chamber 3, and fixedly connected to the side wall. The bottom end of water inlet pipe 14 is closed. Water inlet pipe 14 is installed in conjunction with air outlet pipe 15, with the spiral shape of water inlet pipe 14 corresponding to the spiral shape of air outlet pipe 15. In this embodiment, the spiral radius of water inlet pipe 14 is larger than that of air outlet pipe 15, and the diameter of water inlet pipe 14 is smaller than that of air outlet pipe 15. All components on water inlet pipe 14 are... Several nano-microbubble generators 13 are uniformly installed, one of which is installed at the bottom of the water inlet pipe 14 to prevent water from being stored at the bottom of the water inlet pipe 14 for a long time and unable to be discharged. The output end of each nano-microbubble generator 13 is connected to the air outlet pipe 15. After the water in the water inlet pipe 14 passes through the nano-microbubble generator 13, a large number of negatively charged micro-nano bubbles are generated and sprayed out instantly, forming a micro-nano bubble water curtain in the air outlet pipe 15 to purify the gas in the air outlet pipe 15.

[0026] The inlet pipe 14 is connected to a water supply mechanism; the water supply mechanism can supply pressurized water from the clean water in the water tank 5 to the inlet pipe 14.

[0027] A drainage mechanism is installed at the bottom of the vent pipe 15, which can drain the water inside the vent pipe 15 to the outside of the vent pipe 15.

[0028] The drainage mechanism includes a drain pipe 16, which is connected to the bottom of the vent pipe 15. The drain pipe 16 is fixedly connected to the bottom of the vent pipe 15. A U-shaped pipe 17 is installed at the bottom of the drain pipe 16. The U-shaped pipe 17 is fixedly connected to the bottom of the drain pipe 16 through a flange structure. Water can be stored in the U-shaped pipe 17 to prevent gas in the vent pipe 15 from entering the water tank 5 through the U-shaped pipe 17. When the water level on the side of the U-shaped pipe 17 connected to the bottom of the drain pipe 16 is too high, the excess water will be discharged from the other end of the U-shaped pipe 17.

[0029] In the initial state, the U-shaped tube 17 contains water. The U-shaped tube 17 is designed to prevent the exhaust gas in the exhaust pipe 15 from escaping through the U-shaped tube 17, allowing the exhaust gas to move upward within the exhaust pipe 15. During the exhaust gas treatment process, water continuously flows from top to bottom into the drain pipe 16. When the water level at the end of the U-shaped tube 17 connected to the drain pipe 16 is too high, the water in the drain pipe 16 can fall into the water tank 5 from the other end of the U-shaped tube 17.

[0030] The upper part of the outer wall of the water tank 5 is provided with an inlet 9, and the lower part of the outer wall of the water tank 5 is provided with a drain outlet 6. Both the inlet 9 and the drain outlet 6 are equipped with control valves. The inlet 9 is used to inject fresh clean water, and the drain outlet 6 is used to discharge the sewage in the water tank 5 that has undergone the purification process but has not been effectively purified.

[0031] The water supply mechanism includes an outlet pipe 7, which is fixedly connected to the lower part of the side wall of the water tank 5. Specifically, the outlet pipe 7 is fixedly connected to the side wall of the water tank 5 through a flange structure. The outlet pipe 7 passes through the side wall of the water tank 5. One end of the outlet pipe 7 outside the water tank 5 is connected to a water pump 8. The water pump 8 is connected to an inlet pipe 11, which is connected to an inlet pipe 14. The water pump 8 can draw water out of the water tank 5 through the outlet pipe 7 and transport it to the inlet pipe 11. The water pump 8 also increases the water pressure during the transportation process.

[0032] A filter 18 is installed at one end of the water outlet pipe 7 inside the water tank 5. The filter 18 can filter out some impurities in the water, making the water coming out of the water outlet pipe 7 cleaner. The purification effect is better than that of water that has not passed through the filter 18.

[0033] A fan 2 is installed at the air outlet 1. The fan 2 is connected to the air supply pipe 19. The fan 2 can accelerate the discharge of the purified waste gas from the air outlet 15. The gas passing through the fan 2 enters the air supply pipe 19 and is transported to the next section.

[0034] The top of the water tank 5 is provided with a water tank hole 10, which is used for the flow of gas. Its function is to maintain the pressure balance inside the water tank 5 and prevent negative pressure from occurring.

[0035] After being pressurized by a high-pressure pump, clean water enters the micro-nano bubble generating device. Inside the device, a large number of micro-nano bubbles are generated in the clean water. Because of their large amount of negative charge, these micro-nano bubbles can quickly capture odor molecules with positive charge. At the moment the bubbles annihilate, the odor molecules are decomposed under high temperature and pressure. The large number of hydroxyl radicals generated during the annihilation can quickly oxidize the odor-causing groups, thereby achieving the purpose of purifying odorous waste gas.

[0036] In summary, in actual use, a certain amount of clean water is first injected into the water tank 5 through the water inlet 9. The water pump 8 is then turned on, allowing the water to enter the water inlet pipe 14 from the water tank 5 under the action of the water pump 8. The water entering the water inlet pipe 14 passes through the nano-microbubble generator 13 and is sprayed into the air outlet pipe 15, forming a micro-nano bubble water curtain in the air outlet pipe 15. The air inlet 4 is controlled to allow the exhaust gas to enter and exit from the air inlet 4 into the air outlet pipe 15. The exhaust gas is purified by passing through several micro-nano bubble water curtains in the air outlet pipe 15. After purification, it is discharged from the air outlet 1. A large number of micro-nano bubbles are generated in the clean water in the micro-nano bubble generator 13. Because the micro-nano bubbles carry a large number of negative charges, they can quickly capture odor molecules with positive charges. At the moment of bubble annihilation, the odor molecules are decomposed under high temperature and high pressure. The large number of hydroxyl free radicals generated during annihilation can quickly oxidize the odor-producing groups, thereby achieving the purpose of purifying the odor exhaust gas.

[0037] The water sprayed into the air outlet pipe 15 by the nano microbubble generator 13 will flow downwards due to gravity. When it reaches the bottom of the air inlet pipe, it will continue to flow down into the U-shaped pipe 17 through the drain pipe 16. When the water in the U-shaped pipe 17 exceeds the water level in the U-shaped pipe 17, the water will be discharged from the end away from the drain pipe 16 into the water tank 5. When the water purification efficiency in the water tank 5 is too low and normal purification cannot be carried out, the purification process will be stopped, the drain port 6 will be opened, and the water in the water tank 5 will be discharged out of the water tank 5. Fresh clean water will be added back into the water tank 5 through the water inlet 9.

[0038] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
