Description

Technical Field

[0001] This utility model relates to the field of sterilization and deodorization technology for livestock and poultry houses, and in particular to an energy-saving purification device for livestock and poultry houses. Background Technology

[0002] In livestock and poultry farming, the air quality inside the barns directly affects the growth, health, and production efficiency of livestock and poultry. However, due to the enclosed nature of the farming environment and the accumulation of livestock and poultry excrement, the air inside the barns often contains high concentrations of pollutants such as ammonia, hydrogen sulfide, dust, and harmful microorganisms. Prolonged exposure to this environment can lead to respiratory diseases, decreased production performance, and even large-scale epidemics in livestock and poultry. Furthermore, while traditional ventilation methods can improve air quality to some extent, they are ineffective at removing harmful gases and pathogens, and also tend to result in excessive energy consumption.

[0003] Currently, common air purification equipment on the market mainly uses methods such as single filtration, electrostatic dust removal, and chemical adsorption. These methods are effective in removing some pollutants, but they also have drawbacks such as poor deodorization, high maintenance costs, and limited disinfection effects. Especially for livestock and poultry housing environments, existing equipment struggles to achieve efficient sterilization, water and energy conservation, and long-term stable operation, resulting in poor air purification effects and impacting the growth environment of livestock and poultry.

[0004] To address the aforementioned problems, this utility model provides an energy-saving purification device for livestock and poultry houses. It combines multiple purification technologies such as filtration, spray disinfection, wet curtain adsorption, and water recycling. It uses slightly acidic electrolyzed water for dual sterilization and disinfection, and reduces resource waste through a water recycling system, effectively improving air purification efficiency, reducing operating costs, and optimizing the livestock and poultry farming environment. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide an energy-saving purification device for livestock and poultry houses.

[0006] The purpose of this utility model is achieved as follows: An energy-saving purification device for livestock and poultry houses includes a box body with an openable cover at the top. Ventilation partitions are provided on both the left and right sides of the box body. A pre-filter cotton is provided on the right side of the box body. A filter screen is provided in the box body to the left of the pre-filter cotton. A wet curtain is provided in the box body to the left of the filter screen. A fixing plate is provided in the box body to the left of the wet curtain. A fan is provided on the fixing plate. A spraying mechanism is provided between the filter screen and the wet curtain.

[0007] Furthermore, the spraying mechanism includes a water pipe, with multiple atomizing nozzles evenly arranged on the upper part of the water pipe, and water is supplied to the atomizing nozzles through the water pipe.

[0008] Furthermore, a placement slot is provided on the box below the wet curtain and spray mechanism, and a water storage tank is installed in the placement slot that can be pulled outward, with the lower end of the water pipe located inside the water storage tank.

[0009] Furthermore, a second water pipe is installed inside the upper part of the wet curtain, and multiple evenly distributed spray nozzles are opened on the upper part of the second water pipe. Water is supplied to the spray nozzles through the second water pipe. The spray nozzles are evenly distributed at the upper end of the wet curtain. The lower end of the second water pipe is located in the water storage tank.

[0010] In use, this invention involves adding slightly acidic electrolyzed water to the water storage tank. A controller operates water pump one, water pump two, and a fan. When the fan operates, it draws gas from the right side of the tank into the interior. Once inside, the gas undergoes preliminary filtration through filter cotton, which adsorbs dust and other impurities. The gas then passes through a filter screen filled with activated carbon and red manganese zinc, which preliminarily adsorbs ammonia and hydrogen sulfide, effectively reducing the concentration of these gases.

[0011] After the gas undergoes preliminary deodorization (i.e., preliminary adsorption of ammonia, hydrogen sulfide, etc.) through the filter screen, water from the storage tank is supplied to the atomizing nozzle through the water pipe. The atomizing nozzle sprays slightly acidic electrolyzed water from the box on the left side of the filter screen. The spraying of slightly acidic electrolyzed water sterilizes and disinfects the gas, removing harmful microorganisms and some organic pollutants.

[0012] After being atomized and sprayed, the gas enters the left side of the chamber through the wet curtain. The controller controls the second water pump to drive the water storage inward and supply water to the upper end of the wet curtain through the second water pipe, which then supplies water to the wet curtain through the spray nozzle. The gas must completely pass through the wet curtain before entering the left side of the chamber. The wet curtain is adsorbed with slightly acidic electrolyzed water, which ensures that all the gas must be sterilized and disinfected by slightly acidic electrolyzed water to remove harmful microorganisms and some organic pollutants before entering the left side of the chamber for subsequent discharge.

[0013] The system is equipped with atomizing nozzles that work simultaneously with the evaporative cooling pad to sterilize and disinfect the gas. This avoids poor sterilization and disinfection results caused by excessively fast airflow or the inability of the slightly acidic electrolyzed water on the evaporative cooling pad to sterilize effectively in a timely manner. Therefore, the system with atomizing nozzles and evaporative cooling pads working simultaneously can effectively improve the efficiency of gas sterilization and disinfection.

[0014] Additionally, the slightly acidic electrolyzed water flowing down from the wet curtain and the water sprayed from the atomizing nozzles flow into the water storage tank below. When the water in the storage tank overflows to the height of the separation baffle and enters the separation tank, it can be recycled again. The water in the separation tank is then circulated again through water pipes one and two. When the amount of slightly acidic electrolyzed water in the separation tank is low, it can be replenished in a timely manner through the water supply pipe.

[0015] Concentration detection devices can be installed in the separation tank and the water storage tank as needed (the concentration detection device is existing technology and can detect the effective concentration of slightly acidic electrolyzed water without technical limitations). The effective concentration can be detected in a timely manner to determine whether the slightly acidic electrolyzed water can still play an effective role. If the effective concentration of slightly acidic electrolyzed water is too low, the valve can be opened to discharge the electrolyzed water in the water storage tank through the drain pipe. At the same time, the effective concentration of slightly acidic electrolyzed water can be supplied to the separation tank in a timely manner through the water supply pipe.

[0016] When cleaning or replacing components such as the filter screen, wet curtain, and filter cotton inside the tank is required, the cover can be opened for maintenance or replacement. To clean the water storage tank, it can be pulled out of the tank. A rubber gasket is installed on the inside of the cover; when the cover is closed on the tank, the rubber gasket adheres to the upper part of the filter screen, wet curtain, and fixing plate, preventing gas from overflowing from these components into the left side of the tank.

[0017] Beneficial effects: This utility model has the following technical effects when used:

[0018] Multiple filtration processes improve air purification efficiency:

[0019] This device employs a combined structure of pre-filter cotton, filter screen, and evaporative cooling pad, achieving multi-layered gas filtration. The filter cotton adsorbs larger dust and impurities, reducing the burden on subsequent filtration structures. The filter screen is filled with activated carbon, manganese zinc oxide, and other materials, which efficiently adsorb harmful gases such as ammonia and hydrogen sulfide, effectively reducing the concentration of odors and pollutants in the air. The evaporative cooling pad further enhances the air purification effect while maintaining air humidity, which is beneficial to the healthy growth of livestock and poultry.

[0020] The atomizing nozzles and the evaporative cooling pads work simultaneously to enhance the sterilization and disinfection effect.

[0021] Water is supplied through a water pipe to the atomizing nozzles, spraying slightly acidic electrolyzed water into the air, effectively killing harmful microorganisms and organic pollutants. As the gas passes through the wet curtain, it undergoes another sterilization treatment with slightly acidic electrolyzed water, ensuring thorough disinfection of all gases and preventing incomplete disinfection due to excessively high airflow speeds. This dual sterilization mechanism enhances the effectiveness of air purification, ensuring air quality meets standards for healthy livestock and poultry farming.

[0022] Energy conservation and environmental protection, water resource recycling:

[0023] The device is equipped with a water storage tank, which is divided into a separation tank and a storage tank by a partition, enabling the recycling of water resources. Water from the wet curtain and atomizing nozzles flows into the storage tank and, when it overflows the partition, enters the separation tank, where it is again circulated and sprayed through water pipes one and two, reducing water waste. When the slightly acidic electrolyzed water in the separation tank decreases, new water can be added through the supply pipe, while expired electrolyzed water can be promptly discharged through the drain pipe, ensuring the effective concentration of the water and improving the sterilization effect of the circulating water.

[0024] Intelligent control improves equipment operational stability:

[0025] The controller can automatically control the operation of water supply pump one, water supply pump two, and the blower, intelligently adjusting airflow and water mist supply to adapt to different environmental needs. An optional concentration detection device can be added to monitor the effective concentration of the slightly acidic electrolyzed water in real time, ensuring the water's sterilization and disinfection capabilities. When the concentration is too low, it can automatically replace or replenish the water, enhancing the equipment's intelligence.

[0026] Easy to maintain, extending equipment lifespan:

[0027] The top of the unit features an openable cover for easy replacement of components such as filter cotton, evaporative cooling pads, and filter screens, extending the equipment's lifespan. The pull-out water tank design makes cleaning and maintenance more convenient, reducing the possibility of equipment blockage and bacterial growth. A rubber gasket on the inside of the cover ensures a tight seal with components like the filter screen and evaporative cooling pad when closed, preventing air short-circuiting and improving filtration efficiency.

[0028] In summary, this utility model, through its innovative design including multiple filtration, dual sterilization and disinfection, water recycling, and convenient maintenance, can efficiently purify the air in livestock and poultry houses, reduce polluting gases, improve the quality of the livestock and poultry breeding environment, and at the same time reduce energy consumption, achieving energy conservation and environmental protection, and has broad application prospects.

[0035] Example 1, as Figure 1-4 As shown, the purpose of this utility model is achieved as follows: An energy-saving purification device for livestock and poultry houses includes a box 1, with a cover 2 that can be opened and closed at the upper end of the box 1. Breathable partitions 3 are provided on both the left and right sides of the box 1. A pre-filter cotton 15 is provided on the right side of the box 1. A filter screen 8 is provided in the box 1 to the left of the pre-filter cotton 15. A wet curtain 11 is provided in the box 1 to the left of the filter screen 8. A fixing plate 12 is provided in the box 1 to the left of the wet curtain 11. A fan 13 is provided on the fixing plate 12. A spraying mechanism is provided between the filter screen 8 and the wet curtain 11.

[0036] The spraying mechanism includes a water pipe 9, with multiple atomizing nozzles evenly arranged on its upper part. Water is supplied to the atomizing nozzles through the water pipe 9. A placement slot is provided on the housing 1 below the wet curtain 11 and the spraying mechanism. A water storage tank 4 is installed in the placement slot and can be pulled outwards. The front side of the water storage tank 4 extends through the lower part of the housing 1 and can be pulled outwards. The lower end of the water pipe 9 is located inside the water storage tank 4, and a water pump is installed on the water pipe 9.

[0037] A water pipe 14 is installed inside the upper part of the wet curtain 11, and a water pump 17 is installed on the water pipe 14. Multiple evenly distributed spray nozzles are opened on the upper part of the water pipe 14, and water is supplied to the spray nozzles through the water pipe 14. The spray nozzles are evenly distributed on the upper end of the wet curtain 11. The lower end of the water pipe 14 is located in the water storage tank 4.

[0038] Both water pipe 9 and water pipe 14 have a flexible and retractable tube structure at the bottom, which can realize the pumping of water in the separation tank, and can also realize the extraction of water storage tank 4 when it is necessary to clean the water storage tank 4.

[0039] A separation partition is installed on the front left side of the water storage tank 4. The height of the separation partition is less than the height of the water storage tank 4. The separation partition divides the water storage tank 4 into a separation tank and a water storage tank. The lower ends of water pipe 1 9 and water pipe 2 14 are both located in the separation tank. A water supply pipe 5 is provided on the upper part of the tank body 1 on the front side of the separation tank. A drain pipe 6 is provided on the lower part of the tank body 1 on the front side of the water storage tank. A valve 7 is installed on the drain pipe 6.

[0040] In use, this utility model adds slightly acidic electrolyzed water to the water storage tank 4. The controller controls the operation of water pump 1, water pump 2, and fan 13. When the fan 13 is working, it draws the gas from the left side of the tank 1 into the tank 1. After entering the tank 1, the gas first passes through the filter cotton 15 for preliminary filtration. The filter cotton 15 adsorbs dust and other impurities. After preliminary filtration, the gas passes through the filter screen 8 for further filtration. The filter screen 8 is filled with activated carbon and red manganese zinc material, which preliminarily adsorbs ammonia, hydrogen sulfide, etc., effectively reducing the concentration of ammonia, hydrogen sulfide, etc. in the gas.

[0041] After the gas undergoes preliminary deodorization (i.e., preliminary adsorption of ammonia, hydrogen sulfide, etc.) through filter screen 8, water from storage tank 4 is supplied to atomizing nozzles via water pipe 9 driven by water pump 1. The atomizing nozzles spray slightly acidic electrolyzed water from the box 1 on the left side of filter screen 8. The spraying of slightly acidic electrolyzed water sterilizes and disinfects the gas, removing harmful microorganisms and some organic pollutants from the gas.

[0042] After being atomized and sprayed, the gas enters the left side of the chamber 1 through the wet curtain 11. The controller controls the water pump 2 to drive the water storage inward and supply water to the upper end of the wet curtain 11 through the water pipe 2 14. The water is then supplied to the wet curtain 11 through the spray nozzle. The gas entering the left side of the chamber 1 must completely pass through the wet curtain 11. The wet curtain 11 is adsorbed with slightly acidic electrolyzed water, so it can be ensured that all the gas must be sterilized and disinfected by slightly acidic electrolyzed water to remove harmful microorganisms and some organic pollutants in the gas before entering the left side of the chamber 1 and being discharged.

[0043] The system is equipped with atomizing nozzles that work synchronously with the evaporative cooling pad 11 to sterilize and disinfect the gas. This avoids poor sterilization and disinfection results caused by excessively fast airflow or the inability of the slightly acidic electrolyzed water on the evaporative cooling pad 11 to sterilize in a timely and effective manner. Therefore, the system of atomizing nozzles and evaporative cooling pad 11 working synchronously to sterilize and disinfect the gas can effectively improve the efficiency of gas sterilization and disinfection.

[0044] Additionally, the slightly acidic electrolyzed water flowing down from the wet curtain 11 and the water sprayed from the atomizing nozzles flow into the water storage tank 4 below. When the water in the storage tank overflows to the height of the separation baffle and enters the separation tank, it can be recycled again. The water in the separation tank is then circulated again through water pipe 9 and water pipe 14. When the amount of slightly acidic electrolyzed water in the separation tank is low, it can be replenished in time through the water supply pipe 5.

[0045] Concentration detection devices can be installed in the separation tank and the water storage tank as needed (the concentration detection device is existing technology and can detect the effective concentration of slightly acidic electrolyzed water without technical limitations) to detect the effective concentration in a timely manner and determine whether the slightly acidic electrolyzed water can still play an effective role. If the effective concentration of slightly acidic electrolyzed water is too low, valve 7 can be opened to discharge the electrolyzed water in the water storage tank through the drain pipe 6, while the effective concentration of slightly acidic electrolyzed water is supplied to the separation tank in a timely manner through the water supply pipe 5.

[0046] When it is necessary to clean or replace the filter screen 8, wet curtain 11, filter cotton 15, etc. inside the housing 1, the cover 2 can be opened for maintenance or replacement. When cleaning the water storage tank 4, the water storage tank 4 can be pulled out from the housing 1 for cleaning. A rubber pad 10 is provided on the inside of the cover 2. When the cover 2 is closed on the housing 1, the rubber pad 10 is in contact with the upper end of the filter screen, wet curtain 11, fixing plate 12, etc., to prevent gas from overflowing from the above components into the left side of the housing 1.
