[0026] See also Figures 1 to 4The present application provides an air purification system for a pasture, comprising: an air intake chimney 100, a gas guide device 200, an acid deodorization mechanism 300 and an activated carbon deodorization mechanism 400; the gas guide device 200 comprises a Y-shaped shell 210, a V-shaped beam 220 and a sealed electromagnetic valve 230, the V-shaped beam 220 is arranged inside the shell 210 and the outer wall of the V-shaped beam 220 and the inner wall of the shell 210 form a first transport channel 240 and a second transport channel 250, one end of the sealed electromagnetic valve 230 is hinged on the V-shaped beam 220 and the inner wall of the shell 210. One end of the shaped beam 220 is used to cover and seal the first transport channel 240 or the second transport channel 250. The gas detector 260 is arranged at the air inlet of the shell 210 and is electrically connected to the sealing solenoid valve 230; the air inlet of the acid deodorization mechanism 300 is connected to the end of the first transport channel 240 away from the sealing solenoid valve 230, which is used for acid deodorization; the air inlet of the activated carbon deodorization mechanism 400 is connected to the end of the second transport channel 250 away from the sealing solenoid valve 230, which is used for activated carbon deodorization.

[0027] One end of the shell 210 is an air inlet, and the two side walls of the V-shaped beam 220 and the inner walls of the shell 210 on both sides of the end away from the air inlet form a first transport channel 240 and a second transport channel 250. The connection between the two side walls of the V-shaped beam 220 is provided with an arc-shaped groove, and a rotating shaft is provided in the groove. One end of the rotating shaft extends out of the shell 210 and is connected to the motor provided on the outer wall of the shell 210. The sealed solenoid valve 230 (using the sealed solenoid valve disclosed in the CNU utility model patent) includes a static iron core end, a moving iron core end and a piston end. The static iron core end is provided with a Two, respectively arranged on the inner walls on both sides of the shell 210, and both are arranged on the extension lines of the two side walls of the V-shaped beam 220, the piston end is fixedly connected to the rotating shaft, and limiting columns are arranged on both sides of the piston end, and the moving iron core end is slidably connected to the piston end. Initially, the moving iron core end is parallel to and overlaps with the outer wall of the V-shaped beam 220 of the first transport channel 240, and the moving iron core end extends into the corresponding static iron core end, so that the moving iron core end covers the air inlet of the second transport channel 250. The gas detector 260 is arranged on the top of the air inlet of the shell 210 for detection. The concentration of ammonia, hydrogen sulfide and other gases in the gas and the ambient temperature are measured, with the gas concentration as the main factor and the ambient temperature as the auxiliary factor. When the odor concentration is lower than the threshold, the gas detector 260 controls the moving iron core end to retract toward the piston end, and turns on the motor. The motor drives the rotating shaft and the piston end fixedly connected to the rotating shaft to rotate, so that the moving iron core end is parallel to and overlaps with the other outer wall of the V-shaped beam 220 of the second transport channel 250, thereby sealing the air inlet of the first transport channel 240, allowing the gas to enter from the second transport channel 250, completing the conversion of the gas flow direction, and removing the activated carbon. The odor removal mechanism 400 adopts but is not limited to deodorization equipment with activated carbon materials such as activated carbon plates and activated carbon particles. On the contrary, when the odor concentration is higher than the threshold, the sealing solenoid valve 230 is covered on the second transport channel 250, and the gas enters the acid liquid deodorization mechanism 300 from the first transport channel 240 to complete the odor purification. The acid liquid deodorization mechanism 300 adopts but is not limited to the reaction mode of the acid solution reacting with the odor, such as the gas entering the acid liquid and the gas passing through the wet curtain 380. The acid solution can be replaced and adjusted accordingly according to the specific chemical composition of the odor.

[0028] Specifically, when the gas detector 260 detects that the temperature is low and the odor concentration is lower than the threshold, the sealing solenoid valve 230 is controlled to cover the air inlet of the first transport channel 240, so that the gas enters the activated carbon deodorization mechanism 400 from the second transport channel 250, and the activated carbon is used to purify the odor, and the acid deodorization mechanism 300 is maintained, and the problem of high power consumption of the acid deodorization mechanism 300 is solved, thereby reducing energy consumption; when the gas detector 260 detects that the temperature is low and the odor concentration exceeds the threshold or the temperature is high and the odor concentration exceeds the threshold, the sealing solenoid valve 230 is controlled to change the covering direction, so that the sealing solenoid valve 230 covers the second transport channel 250, so that the gas enters the acid deodorization mechanism 300 from the first transport channel 240, and the acid solution is used to purify the odor, and the activated carbon deodorization mechanism 400 is maintained. The selection process of the sealing solenoid valve 230 is not repeated, and it is all electronically controlled.

[0029] The air purification system technical solution of the ranch adopted in this application can achieve the following beneficial effects:

[0030] By setting up an acid liquid deodorization mechanism 300 and an activated carbon deodorization mechanism 400 and switching them at different temperatures, the problem that the liquid is easy to freeze in the low temperature in winter and the air in the pasture is difficult to purify is solved. At the same time, the problem that the power consumption and cost of purifying the odor are large when the temperature is low and the odor concentration is relatively low is solved. By switching between them, the problems of continuous purification all year round, the long-term operation of the equipment cannot be stopped, and the maintenance is difficult are solved. By setting up a gas diversion device 200, the gas flow direction is changed, making the conversion of the acid liquid deodorization mechanism 300 and the activated carbon deodorization mechanism 400 more convenient.

[0031] Based on the above scheme, the acid deodorization mechanism 300 includes a first deodorization hood 310, a collecting pool 330, at least two spray rows 320 and at least two wet curtains 380. The air inlet of the first deodorization hood 310 is connected to the end of the first transport channel 240 away from the sealing solenoid valve 230. The collecting pool 330 is arranged at the bottom of one end of the first deodorization hood 310, and the collecting pool 330 stores an acidic solution. The spray row 320 is arranged at the top of the first deodorization hood 310, is connected to the collecting pool 330 by a pipeline, and is electrically connected to the gas detector 260. The wet curtain 380 is arranged at one end of the spray row 320 away from the gas detector 260, and the spray row 320 sprays the acidic solution to the end of the wet curtain 380 away from the collecting pool 330, and falls into the collecting pool 330 along the wet curtain 380.

[0032] The first deodorizing hood 310 is a rectangular sealed box, the air inlet of the first deodorizing hood 310 is connected to the air outlet of the first transport channel 240, and the connection is sealed with materials such as sealant or rubber pads. The collecting pool 330 is a rectangular trough, and the top of the side wall of the collecting pool 330 is provided with a slope inclined inside the collecting pool 330. The length of the collecting pool 330 is one-third of the length of the first deodorizing hood 310, and the collecting pool 330 is fixedly connected to the bottom of the first deodorizing hood 310 near the first transport channel 240. A water pump is provided in the collecting pool 330, and the water pump is electrically connected to the gas detector 260. Three spray discharges 320 are provided, and three wet curtains 380 are also provided. The apertures on the three wet curtains 380 gradually decrease from one end close to the air inlet of the first deodorizing hood 310 to the end far away from the air inlet of the first deodorizing hood 310. For example, the apertures are 20 mm, 8 mm, and 5 mm. The odor concentration purified by the wet curtains 380 is the highest at first, and then decreases in sequence, so that the corresponding apertures are successively The water outlet of the spray row 320 is inclined toward the direction of the wet curtain 380, and the vertical projections of the three spray rows 320 and the three wet curtains 380 are all in the collection tank 330. The water inlet of each spray row 320 is connected to the water outlet pipe of the water pump. The water outlet of the water pump can be provided with a liquid diverter. The water outlet of the water pump extends into the bottom of the collection tank 330. The spray row 320 and the wet curtain 380 are spaced apart along the width direction of the first deodorizing hood 310 in the first deodorizing hood. The top of the odor hood 310, when in use, adds an acidic solution into the collection pool 330, and the gas detector 260 detects the concentration of gases such as ammonia and hydrogen sulfide in the gas to control the gas to enter the first odor hood from the first transport channel 240, and the gas detector 260 controls the water pump to start, so that the spray 320 sprays the acidic solution onto the wet curtain 380, and the odor passes through the wet curtain 380 and reacts with the acidic solution to remove gases such as ammonia and hydrogen sulfide, thereby playing a purification role.

[0033] In a preferred implementation scheme, in order to consider the convenience of operation, an automatic acid adding tank 340 is provided at one end of the collection pool 330 away from the air inlet of the first deodorizing hood 310, and the discharge port of the automatic acid adding tank 340 is connected to the pipeline of the collection pool 330, and the feed port of the automatic acid adding tank 340 is provided with a first one-way valve and extends out of the first deodorizing hood 310.

[0034] A support frame is provided at the bottom of the automatic acid adding tank 340 to raise the discharge port of the automatic acid adding tank 340, so that the discharge port of the automatic acid adding tank 340 is tilted downward and extends into the collecting tank 330. The side walls of the collecting tank 330 and the side walls of the deodorizing hood are both provided with liquid observation areas for observing the storage amount of the acid solution in the collecting tank 330. A solenoid valve 342 is provided at the discharge port of the automatic acid adding tank 340. The switch of the solenoid valve 342 is provided outside the deodorizing hood. The opening and closing of the solenoid valve 342 is controlled by electrical connection. The feed port of the automatic acid adding tank 340 extends out of the first deodorizing hood 310, and the contact part is treated with a sealing strip. When the first one-way valve is closed, the gas phase space of the automatic acid adding tank 340 is closed. The first one-way valve can be opened to add acid solution to the automatic acid adding tank 340. By providing the automatic acid adding tank 340, the storage amount of the acid solution is increased, so that the increase and replacement of the acid solution in the collecting tank 330 are more convenient.

[0035] In a preferred embodiment, a meter 341 and a solenoid valve 342 are provided on the discharge port of the automatic acid adding tank 340 . The meter 341 is used to detect the amount of acid added, and the solenoid valve 342 is electrically connected to the meter 341 .

[0036] Specifically, the discharge port of the automatic acid adding tank 340 is inclined at 60°, and the length of the automatic acid adding tank 340 is the same as the width of the first deodorizing cover 310. The acidic solution enters the collecting tank 330 along the slope by gravity, and the acidic solution flows obliquely to the solenoid valve 342. After the volume of the acid is measured by the meter 341, the solenoid valve 342 is opened, and the acidic solution flows into the collecting tank 330 along the inclination angle. The meter 341 can adopt but is not limited to a one-way valve, a solenoid valve 342 and other valves. The solenoid valve 342 is arranged at one end of the discharge port of the automatic acid adding tank 340 near the collecting tank 330, and the valve is arranged in the middle of the discharge port of the automatic acid adding tank 340. The solenoid valve 342 is closed first, and when the acidic solution flows and fills the automatic acid adding tank 3 40, close the valve, open the solenoid valve 342, so that the acid solution between the solenoid valve 342 and the valve flows into the collection tank 330, then close the solenoid valve 342, open the valve, and when the acid solution flows and fills the discharge port of the automatic acid adding tank 340, close the valve. When the meter 341 uses the solenoid valve 342 door, the meter 341 senses the liquid level of the solenoid valve 342 and the meter 341 component, automatically opens or closes, completes the metering and transportation of the acid solution, reduces manual operation, reduces labor intensity, and realizes quantitative acid addition through the meter 341 and the solenoid valve 342, making the operation more convenient, the acid addition amount more accurate, and reduces the excessive waste of the acid solution in the collection tank 330, thereby reducing the cost of use.

[0037] In a better embodiment, for convenience of operation, a liquid level sensor 331 is provided in the collection tank 330 , and the liquid level sensor 331 is electrically connected to the solenoid valve 342 . The liquid level sensor 331 is used to detect the volume of the acid solution in the collection tank 330 .

[0038] Specifically, a liquid level sensor 331 is provided at one end of the collection pool 330 close to the automatic acid adding tank 340. The liquid level sensor 331 continuously detects the volume of the acid solution in the collection pool 330. When the volume of the acid solution is less than a threshold value, the solenoid valve 342 opens, and the meter 341 adds the measured acid solution into the collection pool 330 along the slope of the discharge port of the automatic acid adding tank 340 by its own weight, so that the volume of the acid solution in the collection pool 330 is replenished and exceeds the threshold value of the liquid level sensor 331, thereby solving the problem that the acid solution in the collection pool 330 is insufficient to supply the acid solution for spraying by the spray discharge 320 due to the loss of acid solution during the spraying process. At the same time, through the electrical connection between the liquid level sensor 331 and the solenoid valve 342, the monitoring of personnel is reduced, and the operation is more convenient.

[0039] Based on the above scheme, for convenience, a drainage trough 350 is provided at the bottom of the automatic acid adding tank 340, the water inlet of the drainage trough 350 is connected to the water outlet pipe of the collection tank 330, and the water outlet of the drainage trough 350 is provided with a second one-way valve and extends out of the bottom of the first deodorizing hood 310.

[0040] The drainage trough 350 is arranged at the bottom of the automatic acid adding tank 340 and is fixedly connected to the bracket at the bottom of the automatic acid adding tank 340. A heightening pad is arranged at the bottom of the collecting tank 330. The discharge port of the collecting tank 330 extends downwardly into the drainage trough 350 at an angle. The drainage trough 350 is arranged with a slope of 15° along the width direction of the first deodorizing hood 310. The drainage trough 350 is arranged with a slope of 15° along the length direction of the first deodorizing hood 310. The second one-way valve is arranged at the lowest point of the drainage trough 350 and extends out of the first deodorizing hood 310. The contact part is sealed with sealant. When the acid solution in the collection tank 330 is used multiple times or needs to be replaced, the valve at the discharge port of the collection tank 330 and the second one-way valve are opened, and the acid solution in the collection tank 330 flows into the drain trough 350, and then flows out of the first deodorizing hood 310 from the second one-way valve. After the discharge is completed, the valve at the water outlet of the collection tank 330 and the second one-way valve are closed, and then the automatic acid adding tank 340 is used to supplement the acid solution, thereby solving the problem of replacing the acid solution in the collection tank 330 and making the operation simpler and more convenient.

[0041] In the optimization scheme, in order to reduce the energy consumption of subsequent processes, an air rectifier 370 is provided on the top of the automatic acid adding tank 340, and the water outlet of the air rectifier 370 is connected to the water inlet of the drainage groove 350. The length direction of the air rectifier 370 coincides with the width direction of the first deodorizing hood 310. The air rectifier 370 is arranged on the automatic acid adding tank 340, and the end of the air rectifier 370 away from the automatic acid adding tank 340 is sealed and connected to the top of the first deodorizing hood 310. The water outlet of the air rectifier 370 extends into the drainage groove 350. When the gas passes through the wet curtain 380, the moisture contained in the gas is reduced to water droplets by the air rectifier 370, and most of the moisture in the air is removed and flows into the drainage groove 350 for storage, and is discharged together with the drainage of the drainage groove 350. By adopting the air rectifier 370, the moisture content in the gas is reduced, and the energy consumption of deodorization in the subsequent process is reduced, thereby reducing the cost.

[0042] In a preferred embodiment, the activated carbon deodorization mechanism 400 includes a second deodorization hood 410 and a plurality of activated carbon deodorization plates 420, the air inlet of the second deodorization hood 410 is connected to one end of the second transport channel 250 away from the sealing solenoid valve 230, and the plurality of activated carbon deodorization plates 420 are arranged in the second deodorization hood 410 and perpendicular to the gas flow direction.

[0043] After the temperature drops, the sealing solenoid valve 230 covers and seals the air inlet of the first transport channel 240, and the odor enters the second deodorizing hood 410 from the second transport channel 250, and vertically passes through several layers of activated carbon deodorizing plates 420 in sequence along the length direction of the second deodorizing hood 410 to complete the gas purification. The activated carbon deodorizing mechanism 400 is provided to solve the problem that liquids are easy to freeze in low temperatures in winter and the air in the pasture is difficult to purify. At the same time, the problem of continuous purification all year round, the inability to stop the long-term operation of the equipment, and the difficulty in maintenance is solved.

[0044] In the preferred embodiment, a sterilization mechanism 500 is further included, and an air inlet of the sterilization mechanism 500 is respectively connected to an air outlet of the acid deodorization mechanism 300 and an air outlet of the activated carbon deodorization mechanism 400.

[0045] The sterilization mechanism 500 uses but is not limited to any sterilization equipment such as an ozone generator, an ultraviolet lamp, etc., to eliminate air colonies. The gas purified by the active deodorization mechanism or the acid deodorization mechanism 300 enters from the air inlet of the sterilization mechanism 500 and is sterilized twice to make the gas cleaner.

[0046] Based on the above solution, the air outlet of the sterilization mechanism 500 is provided with a dehumidifier 360 , and the cross-sectional dimension of the dehumidifier 360 in the vertical direction is the same as the cross-sectional dimension of the air outlet of the sterilization mechanism 500 in the vertical direction.

[0047] The dehumidifier 360 uses surface cooling dehumidification. After being sterilized by any sterilization equipment such as an ozone generator or an ultraviolet lamp, there is still moisture in the air that has not been removed by the air rectifier 370. The sterilized air is dehumidified for the second time to make the air entering the subsequent process drier, thereby reducing energy consumption.

[0048] The above-described embodiments only express the way of equipment layout of the present application, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent application; it should be pointed out that for ordinary technicians in this field, several adjustments and improvements can be made without departing from the concept of the present application, which all belong to the scope of protection of the present application; therefore, the scope of protection of the patent of this application shall be based on the attached claims.
