[0034] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] like Figures 1-2 As shown, this utility model embodiment provides a deodorization system that can be applied in livestock and poultry breeding systems to deodorize the waste gas generated in the livestock and poultry breeding systems.

[0036] The deodorization system includes a water purifier 1, an electrolysis generator 2, a small molecule generator 3, a micro-nano generator 4, and an ozone generator 5.

[0037] Among them, the water purifier 1 is provided with a first inlet a and a first outlet b, and the first inlet a is connected to the water source through the water inlet pipe 11; the electrolyte generator is provided with a second inlet c and a second outlet d, and the second inlet c is connected to the first outlet b; the small molecule generator 3 is provided with a third inlet e and a third outlet f, and the third inlet e is connected to the second outlet d; the micro-nano generator 4 is provided with a fourth inlet g, a fourth outlet h and an air inlet i, and the fourth inlet g is connected to the third outlet f; the ozone generator 5 is provided with an air outlet j, and the air outlet j is connected to the air inlet i; the spray device 6 is provided with a sixth inlet k and a sixth outlet l, and the sixth inlet k is connected to the fourth outlet h.

[0038] Water enters the water purifier 1 through the inlet pipe 11. The water purifier 1 filters and purifies the water to make the water pure.

[0039] The purified water then enters the electrolyte generator, which performs micro-electrolysis on the purified water, causing the electron cloud inside the water molecules to become biased, resulting in a negative charge potential for the entire water molecule. This negative potential can affect the movement of water molecules and their interaction with other substances, thereby affecting the physical and chemical properties of water, enhancing its permeability and solubility, and thus promoting the faster dissolution of components in the exhaust gas into the water mist.

[0040] The water that has undergone micro-electrolysis then enters the small molecule generator 3, which is used to process large water molecule clusters into small water molecule clusters. This results in lower surface tension, lower viscosity, and stronger permeability and solubility of the water, thereby promoting the faster dissolution of components in the exhaust gas into the water mist.

[0041] Small water molecule clusters enter the micro-nano generator 4, and ozone generated by the ozone generator 5 also enters the micro-nano generator 4 simultaneously. The small water molecule clusters and ozone mix in the micro-nano generator 4 to produce a large amount of micro-nano ozone bubble water. The bubbles in the micro-nano ozone bubble water increase the contact area between ozone and water, and because the bubbles are small in size, the buoyancy they experience in the water is minimal, ensuring that the bubbles remain in the water for a longer time, thereby increasing the residence time of ozone in the water. Therefore, micro-nano ozone bubble water can greatly increase the solubility of ozone in water, thereby increasing the amount of hydroxyl radicals generated in the water.

[0042] The spraying device 6 then sprays the micro-nano ozone bubble water through the sixth outlet 1 to fully mix it with the exhaust gas. The hydroxyl radicals in the micro-nano ozone bubble water have a strong oxidizing effect on ammonia, hydrogen sulfide and various organic compounds in the exhaust gas, thereby achieving the effect of removing odors from the exhaust gas.

[0043] This deodorization system purifies the water using a purifier to ensure its purity and reduce the probability of clogging in the spray device 6. Then, the water is electrolyzed using an electrolysis generator 2 and a small molecule generator 3 to generate small molecule clusters, increasing its solubility in ozone and further enhancing the deodorization effect. By combining an ozone generator 5 with a micro-nano generator 4, the generation of hydroxyl radicals is increased, thereby improving the deodorization effect of the micro-nano ozone bubble water. This system is also cost-effective and energy-efficient, and produces no wastewater.

[0044] Optionally, an electronic pressure gauge 111 and a first solenoid valve 8 are installed on the water inlet pipe 11. The electronic pressure gauge 111 is used to detect the pressure of the water inlet pipe 11. When the pressure meets the set conditions, the deodorization system controls the first solenoid valve 8 to open and make the system run.

[0045] Optionally, the micro / nano generator 4 includes a water tank 41 and a micro / nano generator 42. A fourth inlet g and a fourth outlet h are provided on the water tank 41. The water tank 41 is also provided with a circulation inlet m and a circulation outlet n. An air inlet i is provided on the micro / nano generator 42. The micro / nano generator 42 is also provided with a liquid inlet o and a mixing outlet p. The circulation outlet n is connected to the liquid inlet o, and the mixing outlet p is connected to the circulation inlet m. Small molecule cluster water enters the water tank 41 through the fourth inlet g. The small molecule cluster water in the water tank 41 then flows out through the circulation outlet n and enters the micro / nano generator 42 through the liquid inlet o. Ozone simultaneously enters the micro / nano generator 42 through the air inlet i. In the micro / nano generator 42, the small molecule cluster water and ozone are mixed to form micro / nano ozone bubble water, which then enters the water tank 41 through the circulation inlet m. After the system is turned on, it can be circulated multiple times before being output through the fourth outlet h. As the micro-nano ozone bubble water in the water storage tank 41 is output through the fourth outlet h, it will also flow out through the circulation outlet n and enter the micro-nano generator 42 through the liquid inlet o to mix with ozone again before entering the water storage tank 41. This continuous cycle makes the ozone concentration in the micro-nano bubble water higher, thus improving the effect of removing odors from the exhaust gas.

[0046] In this embodiment, a circulation pump 43 is installed on the pipeline between the circulation outlet n and the liquid inlet o. The circulation pump 43 can provide power for the circulation of water in the water storage tank 41 (including small molecule cluster water entering through the fourth inlet g and micro-nano ozone bubble water entering through the circulation inlet m).

[0047] Optionally, the outlet j of the ozone generator 5 is connected to a first pipe and a second pipe. The end of the first pipe away from the outlet j is connected to the inlet i of the micro / nano generator 42, and the end of the second pipe away from the outlet j is connected to the pipe between the circulation outlet n and the liquid inlet o. Most of the ozone generated by the ozone generator 5 enters the micro / nano generator 42 through the inlet i, while the remaining ozone first enters the pipe between the circulation outlet n and the liquid inlet o to mix with water, and then enters the micro / nano generator 42 through the liquid inlet o. This structure can further increase the ozone content.

[0048] Optionally, the water storage tank 41 is equipped with a first level gauge 411, a second level gauge 412, and a third level gauge 413, arranged in ascending order of height from bottom to top within the water storage tank 41. When the water level in the water storage tank 41 reaches the second level gauge 412, the circulation pump 43 starts to transport the water in the water storage tank 41 to the micro-nano generator 42. At the same time, the ozone generator 5 starts, transporting the generated high-concentration ozone to the micro-nano generator 42 to mix with the water, thereby producing micro-nano ozone bubble water. Simultaneously, the micro-nano ozone bubble water in the water storage tank 41 is also output through the spray device 6. When the water level in the water storage tank 41 reaches the third level gauge 413, the water inlet pipe 11 stops supplying water. When the water level in the water storage tank 41 drops to the first level gauge 411, the deodorization system alarms and stops the entire system.

[0049] Optionally, the second inlet c and the first outlet b are connected by a buffer tank 7. The buffer tank 7 is equipped with a seventh inlet q and a seventh outlet r. The seventh inlet q is connected to the first outlet b, and the seventh outlet r is connected to the second inlet c. By setting up the buffer tank 7, a buffer zone is formed in this deodorization system to facilitate control.

[0050] To cool the ozone generator 5, optionally, the ozone generator 5 is also equipped with a fifth inlet s and a fifth outlet t, and the buffer water tank 7 is also equipped with a return port u. The fifth inlet s is connected to the pipeline between the seventh outlet r and the second inlet c, and the fifth outlet t is connected to the return port u. When the water in the buffer water tank 7 enters the electrolysis generator 2, a portion of it will enter the ozone generator 5 through the fifth inlet s and be cooled, and then be output through the fifth outlet t and returned to the buffer water tank 7 through the return port u.

[0051] In this embodiment, a power pump 71 is installed inside the buffer tank 7. The buffer tank 7 is also equipped with a backwash return port v. The output port of the power pump 71 is equipped with an output pipe, which is divided into two paths. One path connects to the seventh outlet r, and the other path connects to the backwash return port v. The backwash return port v is also connected to the pipeline between the first outlet b and the seventh inlet q. A second solenoid valve 9 is installed on the pipeline between the first outlet b and the seventh inlet q. The position on the pipeline between the first outlet b and the seventh inlet q that connects to the backwash return port v is located upstream of the second solenoid valve 9, which is equivalent to the backwash return port v being directly connected to the first outlet b. A third solenoid valve 10 is installed on the pipeline between the backwash return port v and the first outlet b. The second solenoid valve 9 and the third solenoid valve 10 are connected in parallel. When the deodorization system is operating normally, the second solenoid valve 9 is open and the third solenoid valve 10 is closed. When the power pump 71 is turned on, it can transport the water in the buffer tank 7 in the forward direction. When it is necessary to backwash the water purifier 1, the second solenoid valve 9 is closed and the third solenoid valve 10 is opened. The power pump 71 can transport water through the backwash return port v to the water purifier 1 and discharge it through the drain port of the water purifier 1.

[0052] Optionally, the buffer tank 7 is equipped with a fourth level gauge 72, a fifth level gauge 73, and a sixth level gauge 74, which are arranged at intervals from low to high within the buffer tank 7. The height from low to high is the direction from bottom to top within the buffer tank 7. When the liquid level in the buffer tank 7 reaches the fifth level gauge 73, the power pump 71 starts, and the water is processed by the electrolysis generator 2 and the small molecule generator 3 before being transported to the water storage tank 41. A portion of the water is diverted to the ozone generator 5 for cooling. When the liquid level in the buffer tank 7 reaches the sixth level gauge 74, the first solenoid valve 8 closes, and the water inlet pipe 11 stops supplying water. When the water level in the buffer tank 7 drops to the fourth level gauge 72, the deodorization system stops operating.

[0053] Optionally, the spraying device 6 includes a high-pressure pump 61 and a spray pipe 62. The spray pipe 62 has a sixth inlet k and multiple sixth outlets l. The sixth outlet l is provided with a spray nozzle 621. After the high-pressure pump 61 is turned on, the micro-nano ozone bubble water in the water storage tank 41 enters the spray pipe 62 and is sprayed out through the spray nozzle 621.

[0054] In this embodiment, a fourth solenoid valve 20 is installed on the pipeline between the seventh outlet r and the second inlet c; a fifth solenoid valve 30 is installed between the sixth outlet l and the spray nozzle 621.

[0055] When the deodorization system is running, when the electronic pressure gauge 111 detects that the pressure in the inlet pipe 11 has reached the set condition, the first solenoid valve 8, the second solenoid valve 9, and the fourth solenoid valve 20 are all opened, and water begins to enter the buffer tank 7. When the liquid level in the buffer tank 7 reaches the fifth level gauge 73, the power pump 71 is turned on and the water in the buffer tank 7 enters the storage tank 41 after passing through the electrolysis generator 2 and the small molecule generator 3. When the liquid level in the storage tank 41 reaches the second level gauge 412, the circulation pump 43 and the ozone generator 5 are turned on, and the small molecule cluster water and ozone in the storage tank 41 are mixed through multiple circulations. Then, the high-pressure pump 61 and the fifth solenoid valve 30 are turned on, so that the micro-nano ozone bubble water is sprayed out through the spray nozzle 621.

[0056] When the deodorization system needs to backwash the water purifier 1, the first solenoid valve 8, the second solenoid valve 9, the fourth solenoid valve 20, the fifth solenoid valve 30, and the high-pressure pump 61 are all closed, while the third solenoid valve 10 and the power pump 71 are opened, so that the power pump 71 can deliver water from the buffer tank 7 to the water purifier 1 to flush it.

[0057] Optionally, such as Figure 2 As shown, the livestock and poultry breeding system includes a livestock and poultry house 40 and a buffer room 50. The livestock and poultry house 40 is equipped with an exhaust gas outlet, which connects the buffer room 50 and the livestock and poultry house 40. The exhaust end of the buffer room 50 is equipped with a wire mesh 501. A part of the spray pipe 62 extends into the buffer room 50, and the spray nozzle 621 is located inside the buffer room 50. The exhaust gas outlet is equipped with a negative pressure fan 401, which can transport the exhaust gas in the livestock and poultry house 40 to the buffer room 50 through the exhaust gas outlet. Micro-nano ozone bubble water is sprayed into the buffer room 50 through the spray nozzle 621 and mixed with the exhaust gas to achieve the effect of removing odor from the exhaust gas. The buffer room 50 can fully mix the exhaust gas and the micro-nano ozone bubble water, preventing the micro-nano ozone bubble water from dissipating due to wind or direct sunlight. In addition, the exhaust end of the buffer room 50 is equipped with a wire mesh 501 with a mesh size of 1mm*1mm, which enables the wire mesh 501 to intercept most of the dust and hair in the livestock house 40.
