Description

Technical Field

[0001] This utility model relates to the field of pollutant gas treatment technology, and more specifically, to an intelligent control and circulation purification device for pollutant gases from livestock farms. Background Technology

[0002] As the scale of livestock farms continues to expand, the types and concentrations of pollutants are also increasing. Therefore, how to efficiently treat the polluting gases emitted by livestock farms has become an urgent technical problem to be solved.

[0003] Currently, technologies for treating pollutant gases from livestock farms mainly include biofilters, photocatalytic purification, and activated carbon adsorption. While these traditional technologies can reduce pollutant emissions to some extent, they still have significant shortcomings. First, traditional technologies have limited effectiveness when dealing with the combined emissions of multiple harmful gases (such as ammonia) from livestock farms. Although biofilters and activated carbon adsorption can remove some pollutants, their efficiency drops significantly under high loads, and they require frequent material replacement, increasing operating and maintenance costs. Second, most existing purification equipment lacks intelligent control systems and cannot adjust in real time according to changes in pollutant gas concentrations. Existing equipment mostly relies on manual or simple timed control, making it difficult to achieve precise adjustment and flexible response to pollution sources. Especially when pollutant concentrations fluctuate significantly, the inability to adjust purification parameters in a timely manner leads to unstable purification effects. This makes it difficult for existing technologies to meet the needs of large-scale livestock farms for intelligent and efficient treatment. Summary of the Invention

[0022] like Figure 1-3As shown, the intelligent control and circulation purification device for polluted gases in a livestock farm includes a wet curtain 1, a first inlet water pipe 2, a first water tank 3, a first water pump 4, a first outlet water pipe 5, a first water inlet valve 13-1, a first drain valve 13-2, a first acid inlet valve 13-3, a first solenoid valve 18, a second water tank 6, a second inlet water pipe 7, a second water pump 8, a second solenoid valve 9, a return pipe 10, a second acid inlet valve 11-1, a second water inlet valve 11-2, an outlet valve 12, an activated carbon filter 14, a negative pressure fan 15, and louvers 16. Frame 17; The evaporative cooling pad 1 has an input channel and an output channel, wherein the input channel has two inlets (inlet one and inlet two), and the output channel has two outlets (outlet one and outlet two); One end of the first input water pipe 2 is connected to inlet one of the input channel in the evaporative cooling pad 1, and the other end of the first input water pipe 2 is connected to the first water tank 3; the first water pump 4 is connected to the first input water pipe 2; one end of the first output water pipe 5 is connected to outlet one of the output channel in the evaporative cooling pad 1, and the other end of the first output water pipe 5 is connected to the first water tank 3; the first water inlet valve 13-1 is connected to the first water tank 3; the first drain valve 13-2 is connected to the first water tank 3; the first acid inlet valve 13-3 is connected to the first water tank 3; the first solenoid valve 18 is connected to the first output water pipe 5.

[0023] One end of the second input water pipe 7 is connected to the second water tank 6, and the other end of the second input water pipe 7 is connected to the inlet 2 of the input channel in the wet curtain 1. The second water pump 8 is connected to the second input water pipe 7. One end of the return pipe 10 is connected to the outlet 2 of the output channel in the wet curtain 1, and the other end of the return pipe 10 is connected to the second water tank 6. The second solenoid valve 9 is connected to the return pipe 10. The second acid valve 11-1 is connected to the second water tank 6, the second water valve 11-2 is connected to the second water tank 6, and the discharge valve 12 is connected to the second water tank 6.

[0024] The wet curtain 1 is fixedly installed on the frame 17, the first water tank 3 is fixedly installed on the frame 17, and the second water tank 6 is fixedly installed on the frame 17.

[0025] Activated carbon filter 14 is fixedly mounted on frame 17, negative pressure fan 15 is fixedly mounted on frame 17, and louvers 16 are fixedly mounted on frame 17. Negative pressure fan 15 is located between activated carbon filter 14 and louvers 16, with louvers 16 located behind negative pressure fan 15. First water tank 3 is located between wet curtain 1 and activated carbon filter 14, and second water tank 6 is located between wet curtain 1 and activated carbon filter 14.

[0026] A second pH sensor is installed in the second water tank 6 to detect the pH value of the liquid in the second water tank 6. A second conductivity sensor is also installed in the second water tank 6 to detect the conductivity of the liquid in the second water tank 6. A controller and a touch screen can be installed on the frame 17. The second pH sensor is connected to the controller via a signal line, and the touch screen is electrically connected to the controller. The pH value data detected by the second pH sensor is sent to the controller, and the conductivity data detected by the second conductivity sensor is sent to the controller. The touch screen displays the corresponding pH value and conductivity data. The controller can control the operation of the first water pump 4, the second water pump 8, the second solenoid valve 9, and the negative pressure fan 15. The touch screen enables human-machine interaction, facilitating the operation of the equipment by the staff.

[0027] A first pH sensor is installed in the first water tank 3 to detect the pH value of the liquid in the first water tank 3. A first conductivity sensor is also installed in the first water tank 3 to detect the conductivity of the liquid in the first water tank 3. The first pH sensor and the first conductivity sensor are electrically connected to the controller via signal lines. The corresponding pH value and conductivity data are displayed on the touch screen.

[0028] An ammonia sensor is installed between the activated carbon filter 14 and the negative pressure fan 15. The ammonia sensor is electrically connected to the controller via a signal line. The ammonia concentration detected by the sensor is sent to the controller, and the ammonia concentration value can be displayed on the touch screen. The ammonia concentration in the farm should not exceed 5 mg / kg, and the concentration in the pigsty should not exceed 25 mg / kg. Therefore, when the ammonia concentration is greater than the set value of 5 ppm (mg / kg), the controller slows down the negative pressure fan 15 to ensure a more complete neutralization reaction; conversely, when the ammonia concentration is too low (less than the set value of 5 ppm), the controller increases the speed of the negative pressure fan 15.

[0029] When the negative pressure fan 15 is running, the air inside the frame 17 passes through the activated carbon filter 14, which filters the floating dust particles. The air filtered by the activated carbon filter 14 is then output from the louvers 16.

[0030] The process of using the intelligent control and circulation purification device for polluting gases from the above-mentioned livestock farm is as follows:

[0031] The first step is to place it in the breeding farm, add a certain amount of water to the first water tank 3 through the first water inlet valve 13-1, start the first water pump 4, and the water in the first water tank 3 enters the wet curtain 1 through the first inlet water pipe 2, and then flows back to the first water tank 3 through the first outlet water pipe 5, forming a water circulation. The wet curtain 1 purifies the air. The controller controls the first solenoid valve 18 to operate, and the flow rate of the circulating water can be adjusted through the first solenoid valve 18.

[0032] A certain amount of water is injected into the second water tank 6 through the second water inlet valve 11-2, and the second water tank 6 stores water for later use.

[0033] When the negative pressure fan 15 is turned on, the air in the farm is drawn into the frame 17, filtered through the activated carbon filter 14, and then output through the louvers 16.

[0034] The second step involves the following process: When ammonia is present in the air of the farm, the water in the first water tank 3 becomes ammonia water after circulation. When the pH value detected by the first pH sensor and the conductivity detected by the first conductivity sensor reach their set values, the first water pump 4 stops, and the first water tank 3 ceases circulation. Then, the second water pump 8 is started. Water in the second water tank 6 enters the wet curtain 1 through the second input water pipe 7, and after passing through the wet curtain 1, flows back into the second water tank 6 through the return pipe 10, forming a circulation. The flow rate can be adjusted by the second solenoid valve 9. The controller controls the second solenoid valve 9 to adjust the flow rate of the circulating water for better air purification.

[0035] While the second water pump 8 is activated to circulate the water in the second water tank 6, sulfuric acid (or other acidic solution) is added to the first water tank 3 through the first acid addition valve 13-3 to neutralize the ammonia in the first water tank 3. The ammonia and sulfuric acid in the first water tank 3 undergo a neutralization reaction. Once the neutralization reaction is complete (this can be determined by data detected by the first pH sensor and / or the first conductivity sensor), the neutralized liquid is discharged through the first drain valve 13-2. This liquid can then be further processed into fertilizer for recycling. After the liquid in the first water tank 3 is discharged, water is refilled into the first water tank 3 through the first water addition valve 13-1.

[0036] Third, after the water in the second water tank 6 is circulated, it becomes ammonia water. When the pH value detected by the second pH sensor reaches the set value and the conductivity detected by the second conductivity sensor reaches the set value, the second water pump 8 stops, and the second water tank 6 stops circulating. Then the first water pump 4 is started, and the water in the first water tank 3 flows through the wet curtain 1 to purify the air.

[0037] During the period when the water in the first water tank 3 is purifying the air, sulfuric acid (or other acidic solution) is added to the second water tank 6 through the second acid addition valve 11-1 to neutralize the ammonia in the second water tank 6. The ammonia and sulfuric acid in the second water tank 6 undergo a neutralization reaction. After the neutralization reaction is complete (this can be determined by data detected by the second pH sensor and / or the second conductivity sensor), the neutralized liquid is discharged through the discharge valve 12. This liquid can then be further processed into fertilizer for recycling. After the liquid in the second water tank 6 is discharged, water is refilled into the second water tank 6 through the second water addition valve 11-2 for later use.

[0038] Repeat the above steps, alternating between the two water tanks to continuously purify the air.

[0039] When the ammonia sensor detects that the ammonia content in the air is greater than a certain set value, the controller controls the negative pressure fan 15 to slow down so that the neutralization reaction is more complete; when the ammonia sensor detects that the ammonia content in the air is too low (less than a certain set value), the controller controls the negative pressure fan 15 to increase its speed.

[0040] As can be seen, the intelligent control circulating purification device disclosed in this utility model can purify the air through the wet curtain 1, the activated carbon filter 14, and ammonia in the air, and can achieve automated operation.

[0041] The liquid that has undergone neutralization in the second tank 6 is discharged through the discharge valve 12 and can then be centrally processed into fertilizer.

[0042] This invention improves processing efficiency and energy utilization, and also enhances equipment maintenance. It enables intelligent regulation, low energy consumption, and resource recycling while ensuring highly efficient purification.
