[0002] The global livestock industry has evolved towards large-scale and intensive operations, significantly improving production efficiency and resource utilization. However, this has also generated substantial amounts of foul odors, which contain numerous bacteria and viruses, posing a significant risk of disease transmission within farms (such as between adjacent pig pens), and severely impacting farm production and operations. Consequently, sterilization and deodorization control systems for livestock farms have emerged. Their function is to filter and kill bacteria, viruses, and odor-causing agents in the gases emitted from the farm, maintaining the scale of large-scale farms, achieving environmentally friendly operations, and reducing biosecurity risks. However, current sterilization and deodorization systems suffer from limitations such as low levels of intelligence, incomplete pathogen eradication, and the continued presence of disease-prone areas, all contributing to biosecurity risks.

The dosing pipeline module receives a dosing command from the control device and adds the sterilizing agent to the reagent container according to the dosing command.

[0010] In one embodiment, the dosing pipeline module includes a stock solution pipeline module and a clean water pipeline module, wherein: The stock solution pipeline module includes a stock solution storage unit, a dosing solenoid valve, a dosing flow meter, and a stock solution pipeline. The stock solution storage unit and the stock solution pipeline are connected. The dosing solenoid valve and the dosing flow meter are both connected to the control device. The dosing solenoid valve opens the stock solution pipeline according to the dosing command of the control device, so that the sterilizing stock solution in the stock solution storage unit is delivered to the drug container through the stock solution pipeline. The dosing flow meter is used to calculate the flow rate of the sterilizing stock solution delivered by the stock solution pipeline. The clean water pipeline module includes a clean water pipeline, a water replenishment solenoid valve, and a clean water source. The clean water source is connected to the clean water pipeline, and the water replenishment solenoid valve is connected to the control device. The water replenishment solenoid valve opens the clean water pipeline according to the dosing command of the control device, so that the clean water from the clean water source is delivered to the reagent container through the clean water pipeline. The sterilizing agent is prepared by mixing the water and the sterilizing stock solution.

[0011] In one embodiment, the sterilization and deodorization system further includes a sewage discharge module, which includes a sewage discharge solenoid valve, a sewage treatment tank, and a sewage pipeline.

[0014] Beneficial effects This invention provides a sterilization and deodorization system for a livestock farm. The system includes: a sterilization and deodorization chamber equipped with a sterilization and deodorization device and a pathogen detection device. The sterilization and deodorization device sprays a sterilizing agent into the chamber to sterilize and deodorize the gas. The pathogen detection device collects the gas from the chamber and determines the pathogen content based on the collected gas. A control device, electrically connected to the chamber, receives the pathogen content and controls the dosage of the sterilizing agent sprayed by the sterilization and deodorization device based on the pathogen content. Therefore, this invention uses the pathogen detection device in the sterilization and deodorization chamber to collect the gas and obtain pathogen content data. The control device then accurately calculates the dosage of sterilizing agent to be sprayed by the sterilization and deodorization device based on the pathogen content data obtained by the pathogen detection device. This effectively improves the intelligence level of the sterilization and deodorization system, making the entire system more efficient and accurate during operation. Because the spraying dosage of sterilizing agents can be precisely controlled, pathogens can be killed more thoroughly, thus effectively solving the problem of pathogen residue in disease-causing units. The sterilization and deodorization system of this invention provides farms with a more reliable and efficient sterilization and deodorization solution, helping to improve the overall hygiene level of farms and ensuring a healthy growth environment for animals.

[0015] Figure 1 This is a schematic diagram of the structure of a sterilization and deodorization system for a farm provided in an embodiment of the present invention.

[0016] Figure 2 yes Figure 1 The diagram shows the structure of the control device for the sterilization and deodorization system. Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] With the development of breeding technology, the livestock industry is trending towards large-scale and intensive farming. For example, pig farming typically involves large-scale pig farms with multiple pig pens. This large-scale production generates significant amounts of foul odors, which contain numerous bacteria and viruses. These odors can easily spread diseases between adjacent pig pens, posing a serious threat to the farm's production and operation. Current sterilization and deodorization systems usually apply a fixed amount of disinfectant to the pig pens, and the sterilized gas is then directly discharged. This approach cannot tailor the sterilization agent to the specific pathogens present in the pig pens, lacks a high degree of automation, and is prone to incomplete pathogen eradication, leaving disease-prone areas untreated.

[0019] To solve the above-mentioned technical problems, the present invention provides a sterilization and deodorization system for a farm. The sterilization and deodorization system includes: a sterilization and deodorization chamber, wherein the sterilization and deodorization chamber is equipped with a sterilization and deodorization device and a pathogen detection device. The sterilization and deodorization device is used to spray a sterilizing agent into the sterilization and deodorization chamber to sterilize and deodorize the gas in the sterilization and deodorization chamber. The pathogen detection device is used to collect the gas in the sterilization and deodorization chamber and obtain the pathogen content in the sterilization and deodorization chamber based on the collected gas. A control device, electrically connected to the sterilization and deodorization chamber, is used to receive the pathogen content and control the dosage of the sterilizing agent sprayed by the sterilization and deodorization device based on the pathogen content.

[0020] Therefore, the control device of this invention calculates the dosage of sterilizing agent required for the sterilization and deodorization device based on the pathogen content data obtained by the pathogen detection device in the sterilization and deodorization chamber. This effectively improves the intelligence level of the sterilization and deodorization system, making the entire system more efficient and accurate during operation. Because the dosage of sterilizing agent can be precisely controlled, pathogens can be killed more thoroughly, thus effectively solving the problem of pathogen residue in disease-causing units.

[0021] Based on this, please refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of a sterilization and deodorization system for a livestock farm provided in an embodiment of the present invention. Figure 1 As shown, the sterilization and deodorization system 10 includes a sterilization and deodorization chamber 11 and a control device 12.

[0022] The sterilization and deodorization chamber 11 is connected to the pen of the farm (such as the pigsty in a pig farm). Specifically, the sterilization and deodorization chamber 11 includes an air inlet and an air outlet, which are usually located on two opposite walls of the sterilization and deodorization chamber 11. The pen is equipped with an exhaust fan, which outputs the gas from the pen to the ventilation duct, and then transmits it to the air inlet of the sterilization and deodorization chamber 11. The sterilization and deodorization chamber 11 sterilizes and deodorizes the incoming gas, and then it is transmitted to the external environment from the air outlet.

[0023] The sterilization and deodorization chamber 11 is equipped with a sterilization and deodorization device 111 and a pathogen detection device 112. The sterilization and deodorization device 111 is used to spray sterilizing agents into the sterilization and deodorization chamber to sterilize and deodorize the gas inside. The pathogen detection device 112 is used to collect the gas inside the sterilization and deodorization chamber and determine the pathogen content within the chamber based on the collected gas. The control device 12 is electrically connected to the sterilization and deodorization chamber 11 and is used to receive the pathogen content and control the dosage of sterilizing agents sprayed by the sterilization and deodorization device 111 based on the pathogen content.

[0024] Therefore, in this embodiment, the pathogen detection device 112 can accurately calculate and analyze the pathogen content inside the sterilization and deodorization chamber 11. Furthermore, the control device 12 precisely adjusts the dosage of the sterilizing agent based on the detected pathogen content data. Through the cooperation between the pathogen detection device 112 and the control device 12, an intelligent sterilization and deodorization operation process can be achieved. This intelligent operation process can efficiently and effectively sterilize and deodorize the gas inside the sterilization and deodorization chamber 11, thus effectively solving the problem of residual pathogens in the disease-causing unit.

[0025] Optionally, the sterilization and deodorization device 111 includes a sterilization and deodorization pipeline 1111 and a reagent container 1112. The reagent container 1112 contains sterilizing agents, and the sterilization and deodorization pipeline 1111 is connected to the reagent container 1112 to deliver the sterilizing agents in the reagent container 1112 to the target location for spraying. In practical applications, the reagent container 1112 can be a water tank, which can be installed at the bottom of the sterilization and deodorization chamber 11. The target location can be the top or side of the sterilization and deodorization chamber 11, or both the top and side.

[0026] The sterilization and deodorization pipeline 1111 can kill pathogens contained in the gas within the sterilization and deodorization chamber 11. Specifically, the sterilization and deodorization pipeline 1111 includes at least a first spray pipeline 1111A and a second spray pipeline 1111B. The first spray pipeline 1111A and the second spray pipeline 1111B are arranged in different directions to deliver the sterilizing agent to different target locations for spraying. Figure 1 As shown, the first spray pipe 1111A is located at the top of the sterilization and deodorization chamber 11, which can spray the sterilizing agent downwards from the top of the sterilization and deodorization chamber 11. The second spray pipe 1111B is located on the side of the sterilization and deodorization chamber 11. Figure 1 As shown, the sterilization and deodorization chamber 11 is located on the right side, allowing sterilizing agents to be sprayed from the right side to the left side. By spraying sterilizing agents from different target locations (the top and the right side), the gases inside the sterilization and deodorization chamber 11 can be thoroughly sterilized and disinfected, improving the efficiency and effectiveness of sterilization.

[0027] To increase spraying power, the sterilization and deodorization system 10 also includes a first spray pump 13 and a second spray pump 14. The first spray pump 13 is connected to the control device 12 and the first spray pipeline 1111A. After receiving the spraying command from the control device 12, the first spray pump 13 pressurizes the sterilizing agent in the first spray pipeline 1111A to deliver the sterilizing agent to the target location. Figure 1 The top position of the sterilization and deodorization chamber 11 shown.

[0028] The second spray pump 14 is connected to both the control device 12 and the second spray pipeline 1111B. After receiving the spraying command from the control device 12, the second spray pump 14 pressurizes the sterilizing agent in the second spray pipeline 1111B to deliver the sterilizing agent to the target location. Figure 1 The sterilization and deodorization chamber 11 shown is located on the right side.

[0029] Furthermore, a sterilization and deodorization layer 15 is installed between the air inlet and outlet of the sterilization and deodorization chamber 11. The sterilization and deodorization layer 15 contains a sterilization and deodorization agent to sterilize and deodorize the gas in the sterilization and deodorization chamber. Figure 1 As shown, the sterilizing and deodorizing agent can be a packing ball filled with sterilizing raw materials. Multiple packing balls aggregate to form a sterilizing and deodorizing layer 15, which can be a wall structure. A first spray pipe 1111A and a second spray pipe 1111B are respectively located on both sides of the sterilizing and deodorizing layer 15. In this embodiment, gases containing pathogens are blocked by the packing balls of the sterilizing and deodorizing layer 15, adhering to particulate matter and pathogens. Furthermore, a strong oxidizing and reducing sterilizing agent is continuously sprayed onto both sides of the sterilizing and deodorizing layer 15 through the first spray pipe 1111A and the second spray pipe 1111B, destroying the bacterial cell structure and achieving a sterilizing and deodorizing effect.

[0030] The pathogen detection device 112 is positioned between the sterilization and deodorization layer 15 and the air outlet. In other words, the pathogen detection device 112 collects the gas after it has passed through the sterilization and deodorization layer 15 and the sterilization and deodorization device 111. This allows for the detection of the sterilization and deodorization effect of the sterilization and deodorization chamber, which is then fed back to the control device 12. The control device 12 then adjusts the dosage of the sterilizing agent based on the feedback results to achieve the optimal sterilization effect.

[0031] The previous section introduced a method for sterilizing and deodorizing the sterilization and deodorization chamber 11 using the sterilization and deodorization device 111. The sterilizing agent sprayed by the sterilization and deodorization device 111 needs to be replenished in a timely manner to achieve a high-efficiency sterilization effect. Based on this, the sterilization and deodorization system 10 also includes a dosing pipeline module 16. The dosing pipeline module 16 is connected to the control device 12 and the agent container 1112, respectively. The dosing pipeline module 16 receives dosing instructions from the control device 12 and adds sterilizing agent to the agent container 1112 according to the dosing instructions, so that the first spray pipeline 1111A and the second spray pipeline 1111B can continuously spray sterilizing agent onto the sterilization and deodorization layer 15, achieving high-efficiency sterilization and deodorization.

[0032] More specifically, the dosing pipeline module 16 includes a stock solution pipeline module 161 and a clean water pipeline module 162. The stock solution pipeline module 161 includes a stock solution storage device 1611, a dosing solenoid valve 1612, a dosing flow meter 1613, a stock solution temporary storage device 1614, and a stock solution pipeline. The stock solution storage device 1611 is connected to the stock solution pipeline. The dosing solenoid valve 1612 and the dosing flow meter 1613 are both connected to the control device 12. The dosing solenoid valve 1612 opens the stock solution pipeline according to the dosing command from the control device 12, so that the sterilizing stock solution in the stock solution storage device 1611 is transported to the reagent container 1112 through the stock solution pipeline. The dosing flow meter 1613 is used to calculate the flow rate of the sterilizing stock solution transported by the stock solution pipeline. Specifically, the control device 12 calculates the required dosage of the spraying agent based on the pathogen content in the sterilization and deodorization chamber 11. Then, according to the calculated dosage, it controls the dosing solenoid valve 1612 to open, thus opening the raw material pipeline. Simultaneously, it controls the dosing flow meter 1613 to calculate the flow rate of the sterilizing raw material transported through the pipeline. When the flow meter 1613 calculates that the flow rate has reached the required dosage of the spraying agent, the control device 12 controls the dosing solenoid valve 1612 to close, thus shutting off the raw material pipeline. Therefore, this embodiment, through the coordinated operation of the control device 12 and the dosing flow meter 1613, accurately calculates and statistically analyzes the flow rate of the sterilizing raw material, ensuring that the sterilizing agent is precisely delivered to the sterilization and deodorization chamber 11. This not only guarantees that the sterilization and deodorization chamber 11 always receives a sufficient and appropriate amount of sterilizing agent, effectively completing the sterilization and deodorization tasks, but also minimizes waste caused by excessive agent delivery. This refined flow control method not only improves the stability of sterilization effect but also achieves higher efficiency in resource utilization, thus achieving the dual goals of cost saving and environmental protection.

[0033] Understandably, when the amount of sterilizing agent in the reagent container 1112 exceeds a certain value, or when it is not suitable to transfer the agent to the reagent container 1112 during the operation of the sterilization and deodorization device 111, the sterilizing concentrate transferred through the concentrate pipeline can be temporarily stored through the concentrate storage device 1614. At an appropriate time, the sterilizing concentrate in the concentrate storage device 1614 can then be transferred to the reagent container 1112, achieving a rapid transfer effect.

[0034] The above describes a scheme for delivering the sterilization stock solution. In practical applications, most pathogens can be killed in a certain concentration of sterilizing agent. Therefore, directly spraying a high-concentration sterilization stock solution would result in resource waste. Thus, the sterilization stock solution can be diluted according to the characteristics of the pathogens to a concentration range suitable for killing gaseous pathogens. In this case, in addition to the stock solution pipeline module 161 providing the sterilization stock solution, a clean water pipeline module 162 is also needed to provide clean water, so that the sterilization agent can be prepared by mixing the clean water and the sterilization stock solution.

[0035] Specifically, the clean water pipeline module 162 includes a clean water pipeline, a water replenishment solenoid valve 1621, and a clean water source 1622. The clean water source 1622 is connected to the clean water pipeline, and the water replenishment solenoid valve 1621 is connected to the control device 12. The water replenishment solenoid valve 1621 opens the clean water pipeline according to the dosing command from the control device 12, so that the clean water from the clean water source 1622 is delivered to the chemical container 1112 through the clean water pipeline.

[0036] After the sterilization and deodorization chamber 11 is sprayed with a sterilizing and deodorizing agent for sterilization and deodorization, the resulting wastewater needs to be treated to ensure that the discharged aqueous solution meets the standards. Therefore, the sterilization and deodorization system 10 also includes a sewage discharge module 17, which includes a sewage discharge solenoid valve 171, a sewage treatment tank 172, and sewage pipes. The sewage pipes are connected to both the sterilization and deodorization chamber 11 and the sewage treatment tank 172. The sewage discharge solenoid valve 171 is connected to a control device 12. The sewage discharge solenoid valve 171 receives a sewage discharge command from the control device 12 and opens the sewage pipes accordingly, allowing the wastewater in the sterilization and deodorization chamber 11 to be transported through the sewage pipes to the sewage treatment tank 172. After treatment in the sewage treatment tank 172, a compliant aqueous solution is prepared.

[0037] Optionally, the sterilization and deodorization system includes a user interaction module 18, used to provide users with information on the sterilization and deodorization status of the system. The user interaction module 18 may include multiple indicator lights to indicate equipment power supply status, operating status, network connection status with the platform, alarm status, and other information. It may also include a display screen to show equipment parameters and operating status information, enabling functions such as system function debugging and water pump power parameter calibration. It may also include a buzzer to emit key press prompts and alarm sounds.

[0038] The above-mentioned intelligent control is achieved by using control device 12 to control the sterilization and deodorization device 111, the chemical dosing pipeline module 16, and the sewage discharge module 17 in conjunction with the pathogen content in the sterilization and deodorization chamber 11. Please refer to [link / reference]. Figure 2 , Figure 2 yes Figure 1 The diagram shows the structure of the control device. Figure 2 As shown, the control device 12 includes a controller, an input detector, and an output controller. The controller is connected to both the input detector and the output controller. The controller processes the signals detected by the input detector and transmits the processing results to the output controller for output control, thereby achieving intelligent control.

[0039] The input detector includes multiple optocouplers, which detect the on / off signals of the drain solenoid valve, the dosing solenoid valve, and the water supply solenoid valve, forming a closed-loop detection. It also detects the liquid level signal in the stock solution storage and the pulse signal of the dosing flow meter, and records the dosing amount.

[0040] The output controller includes multiple solid-state relays, which respectively control the opening and closing of the chemical dosing and sewage discharge solenoid valve, the chemical dosing solenoid valve, and the water replenishment solenoid valve, as well as the spraying power of the sterilization and deodorization pipeline.

[0041] like Figure 2 As shown, the four optocouplers in the input detector detect the open and closed signals of the following valves respectively: the drain solenoid valve, the dosing solenoid valve, the water replenishment solenoid valve, and the storage valve (the solenoid valve corresponding to the stock solution temporary storage device 1614), forming a closed-loop detection system. Furthermore, one optocoupler detects the high and low liquid levels in the stock solution storage device via feedback from the stock solution storage device. Another optocoupler detects the pulse signal from the dosing flow meter via feedback from the flow meter, recording the dosage.

[0042] The output controller includes six solid-state relay output circuits. Compared to mechanical relays, it eliminates the lifespan issue of mechanical contact operation and enables AC voltage zero-crossing, reducing the impact on the AC power supply system. Two of the outputs have power metering and power detection functions, working with an external high-power AC contactor to control the first spray pump 13 and the second spray pump 14 in the sterilization and deodorization chamber 11. The first spray pump 13 and the second spray pump 14 continuously deliver an aqueous solution mixed with a certain amount of sterilizing agent to the sterilization and deodorization layer 15, achieving sterilization, disinfection, and deodorization of the waste discharged from the enclosure. One output controls the dosing solenoid valve to add a strong oxidizing-reduction sterilizing agent that can kill pathogens to the agent container 1112 in the sterilization and deodorization chamber 11. The dosage is accurately measured by a dosing flow meter, which meets the requirements of strong corrosion resistance and accurate measurement. One output controls the water replenishment solenoid valve to replenish clean water to the agent container 1112, ensuring a continuous water supply. One output controls the drain solenoid valve to discharge dust particles and accumulated germs from the sterilization and deodorization chamber 11, preventing accumulation and overflow. Another output controls the drug storage valve to temporarily store the stock solution in the stock solution storage device 1614.

[0043] The controller coordinates the operation of various functions and connects to the cloud platform via Ethernet (ETH) to enable settings for hardware maintenance parameters, real-time monitoring of hardware operating parameters, graphical display of sterilization and deodorization effects, risk unit early warning, cleaning of the sterilization and deodorization layer, and issuance of equipment maintenance work orders. The cloud platform also allows for remote upgrades of the control device's operating procedures.

[0044] In addition, the control device 12 also includes a power supply circuit, specifically: the input power is AC220V, which outputs DC24V power through the AC-DC (alternating current to direct current) isolated power supply module, and the subsequent DC-DC (direct current to direct current) power supply circuit and LDO circuit to power the internal circuit of the device; it also includes an isolated DC-DC circuit to power the isolated 485 circuit.

[0045] The isolated 485 circuit is powered by an isolated DC-DC circuit. The 485 circuit includes two isolated circuits: one is an isolated 485-1 as a slave device that communicates with the environmental controller to achieve network communication and information exchange; the other is an isolated 485-2 as a master device that can communicate with slave devices with the 485 interface, such as dosing flow meters, temperature and humidity sensors, etc.

[0046] In addition, the control device 12 may also include auxiliary functions, specifically: an RTC module with backup power function that can continuously record date and time; an onboard large-capacity FLASH memory to realize the functions of storing working parameters and temporarily storing batch data; and a Type-C interface to realize local program download and local running and debugging.

[0047] Therefore, the control device 12, through its built-in output controller and power metering module, enables real-time monitoring of electrical parameters such as voltage, current, power, and energy during the operation of the first and second spray pumps. It promptly identifies the operating status of the first and second spray pumps, such as idling, overload, or aging, and issues timely warnings to prevent abnormal damage to these critical and expensive equipment. This ensures continuous water spraying of the sterilization and deodorization layer to kill pathogens, improving system stability and reducing maintenance costs. Furthermore, by connecting a chemical flow meter (either pulse signal type or 485 communication type), it enables the precise application of the core sterilization agent. The precise quantitative detection ensures an effective dose for killing pathogens. Furthermore, by connecting the cloud platform and local LCD screen via a wired network, it is possible to conveniently set equipment maintenance parameters remotely and locally, monitor parameters such as hardware operating power in real time, display sterilization and deodorization effect charts, provide timely warnings for units with risks, and accurately schedule maintenance for equipment such as the sterilization and deodorization layer for targeted operation and maintenance. This improves the intelligence and operational stability of the sterilization and deodorization control system. Finally, in conjunction with a pathogen detection device, the timely detection of sterilization and deodorization effects achieves closed-loop detection of behavior and effect.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
