Description

Technical Field

[0001] This utility model relates to the field of animal husbandry, specifically to a spray deodorization system for livestock and poultry houses. Background Technology

[0002] With the rapid development of large-scale livestock farming, the emission of odorous gases from livestock farms has become increasingly serious. In particular, the treatment of manure from pig farms and cattle farms has become a hot topic in the environmental protection field. As a result, deodorization equipment has emerged, with spray deodorization systems currently being the main type of deodorization equipment.

[0003] Existing spray deodorization systems typically consist of filter media walls, spray equipment, a circulating water tank, wastewater discharge equipment, water replenishment equipment, a pH monitoring device, and chemical dosing equipment. These systems use specially designed filter media walls and spray devices to spray treated aqueous solutions onto the exhaust gas, purifying the air. Through the water film layer of the filter media wall, harmful components in the exhaust gas, such as hydrogen sulfide and ammonia, are captured by water molecules and react with the aqueous solution, thus achieving deodorization.

[0004] However, the existing spray deodorization systems have the following problems: 1) The spiral nozzles used in the spray system are prone to clogging and require manual cleaning, which often requires stopping the system; 2) The water sprayed on the filter wall is easily carried away to the outside by the spray water pressure and the action of the fan, resulting in a waste of water resources; 3) The sewage discharge problem in the circulating water tank lacks automated monitoring and control, and usually relies on manual judgment to carry out sewage discharge operations, which is inefficient and depends on human experience.

[0010] Preferably, it also includes a dosing device, the output end of which is connected to the circulating water tank via a dosing pipe, and a ball valve is installed on the dosing pipe.

[0011] Preferably, the water return plate is set at an angle of 15°-30° to the building's exterior wall.

[0012] Preferably, the return plate includes a polycarbonate sheet and a fiberglass angle steel bracket, with the polycarbonate sheet fixed to the fiberglass angle steel bracket. The first end of the fiberglass angle steel bracket is connected to the bottom end of the filter bracket, and the second end of the fiberglass angle steel bracket is connected to the filter bracket via a connector.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention effectively prevents nozzle clogging by configuring a self-cleaning filter and spray head, reducing the frequency and workload of manual cleaning. Furthermore, the design of the water return plate structure effectively prevents sprayed water from floating outside the filter media wall, reducing water waste. Simultaneously, the use of a conductivity meter and an automatic sewage discharge control system allows for automatic determination of sewage discharge timing based on water quality, achieving fully automated sewage discharge, improving the system's automation level, reducing manual intervention, and increasing overall work efficiency.

[0017] This invention employs a multi-stage sedimentation tank and a self-cleaning filter, which can effectively remove impurities from the water, ensure the quality of the sprayed water, and avoid the impact of water pollution on the deodorization effect.

[0018] This invention solves the problem of nozzle clogging in traditional sprinkler systems by using a vortex nozzle and a self-cleaning filter. The vortex nozzle has a large spray angle, resulting in uniform spraying and effectively preventing clogging by impurities, thus reducing the frequency of manual cleaning. Furthermore, the self-cleaning filter automatically discharges wastewater via differential pressure, and the sprinkler system can continue operating normally without stopping during the discharge process, avoiding manual intervention and ensuring long-term stable operation. This improvement increases the efficiency of the sprinkler system, extends the equipment's lifespan, and reduces operating costs.

[0019] This invention, through the design of a return water plate, prevents water mist outside the filter media wall from drifting out of the system. All drifting water can smoothly flow back to the circulating water tank through the return water plate, achieving efficient water resource recovery and reuse. Traditional spray deodorization systems often waste water, while this invention, through its reverse flow design, maximizes water resource utilization, reduces water costs for system operation, and has a smaller environmental impact.

[0020] This invention automates water quality monitoring and sewage discharge processes by connecting a conductivity meter and a level switch to a sewage pump and a water supply electric valve. The system can automatically adjust its operating status based on real-time water quality conditions, reducing human error and ensuring optimal water quality, thereby improving deodorization efficiency and system stability. Automated control not only enhances operational convenience but also significantly reduces the cost and error risk of manual management. Attached Figure Description

[0023] The embodiments of this utility model will now be described with reference to the accompanying drawings.

[0024] like Figures 1-7 As shown, the livestock and poultry house spray deodorization system of this utility model includes a spray device, a sedimentation tank, a circulating water tank, a filtration device, and an automatic sewage discharge control system.

[0025] Spray System: The spray system is the core component of this system, mainly including a spray pump 18, spray pipes 16, spray branch pipes 26, spray heads 6, and a spray filter wall. The spray pump 18 is located inside the sedimentation tank 9, with its input end connected to the output end of the sedimentation tank 9. The output end is connected to the main spray pipe via a self-cleaning filter 17. The main spray pipe is connected to the spray heads 6 via multiple spray branch pipes 26, each with multiple spray nozzles on its side wall. The spray filter wall is positioned opposite the spray heads 6, forming an effective gas-liquid contact area, which helps to thoroughly purify the exhaust gas. The spray filter wall includes filter media 1, a filter support 2, and a return water plate 5. The return water plate 5 is positioned at a 15°-30° angle to the building wall 4. The return water plate 5 includes a polycarbonate sheet 21 and a fiberglass angle steel bracket 20, with the polycarbonate sheet 21 fixed to the fiberglass angle steel bracket 20. The first end of the fiberglass angle bracket 21 is connected to the bottom end of the filter bracket, and the second end of the fiberglass angle bracket is connected to the filter bracket through the connector 22.

[0026] The circulating water tank 7 is a major component of the water circulation system, with its output end connected to the input end of the sedimentation tank 9. The sedimentation tank 9 consists of three areas (a first sedimentation tank, a second sedimentation tank, and a third sedimentation tank). Wastewater flows through the connecting ports of each sedimentation tank, and impurities settle within each tank area. The first sedimentation tank is connected to the circulating water tank 7 via the first connecting port 23, the second sedimentation tank is connected to the first sedimentation tank via the second connecting port 24, and the third sedimentation tank is connected to the second sedimentation tank via the third connecting port 25. This design allows wastewater to be gradually purified as it flows through each sedimentation tank, providing a clean water source for the spray system.

[0027] The self-cleaning filter 17 and the sewage discharge system: The self-cleaning filter 17 is connected to the spray pump 18, and the filtered water flows to the spray pipe 16. The bottom of the self-cleaning filter 17 has an automatic sewage discharge port, connected to a second sewage discharge pipe 14. Impurities from the discharge port are discharged through an electric sewage discharge valve, ensuring the normal operation of the system. The sewage pump 10 is connected to the sedimentation tank 9 and is responsible for discharging wastewater into the sewage discharge pipe. This mechanical connection structure ensures smooth system operation and continuous water quality improvement.

[0028] The pH meter works in conjunction with the dosing equipment: A conductivity meter 8 is installed inside the circulating water tank 7 to monitor the pH level of the water in real time. The output of the conductivity meter 8 is electrically connected to the dosing equipment 19. When the pH value of the water deviates from the set range, the conductivity meter 8 sends a signal to the dosing equipment 19 to initiate the dosing process. The dosing equipment 19 adds an appropriate amount of chemical agent, such as acidic or alkaline substances, to the circulating water tank 7 through pipes to adjust the water quality to the ideal pH range and optimize the deodorization effect.

[0029] Water replenishment component and level control system: The water replenishment component is connected to the sedimentation tank 9 via a water replenishment pipe, and its output end is connected to the water replenishment electric valve 15. The float valve 12 is a mechanical float valve that can automatically control water replenishment and stop. The water replenishment electric valve 15 and the float valve 12 are connected via a pipe. The level switch 11 is electrically connected to the sewage pump 10 to monitor the water level in the sedimentation tank. The sewage pump stops discharging sewage when the water level is low, ensuring that the water replenishment is always maintained within a reasonable range and guaranteeing continuous system operation.

[0030] The work process is as follows: Waste gas purification process: The waste gas from the breeding room first enters the deodorization system through fan 3, which transports the waste gas from the breeding room to the filter media. Water in the sedimentation tank 9 after adding medicine reaches the spray head 6 through the spray pipe 16. The sprayed water mist comes into contact with the waste gas, and the harmful gases are adsorbed by the filter media 1. The purified air is then discharged.

[0031] The circulating water treatment process involves water flowing sequentially through the circulating water tank 7 and the sedimentation tank 9 (via the first connecting port 23, the second connecting port 24, and the third connecting port 25), and then being further purified by the self-cleaning filter 17 before returning to the spray system. pH control is coordinated with the dosing equipment 19 via the conductivity meter 8 to maintain the optimal pH range and enhance deodorization efficiency.

[0032] Automatic sewage discharge process: When the conductivity meter 8 detects an abnormal water quality, the sewage pump 10 is automatically started, and sewage is discharged through the first sewage pipe 13 and the second sewage pipe 14. The level switch 11 controls water replenishment, and the water replenishment electric valve 15 and the float valve 12 automatically maintain a reasonable water level to ensure continuous operation of the system.

[0033] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
