[0002] With the rapid development of large-scale breeding industries, the problem of waste gas emissions from farms has become increasingly prominent. The waste gas mainly contains harmful components such as ammonia (NH3), hydrogen sulfide (H2S), and volatile organic compounds (VOCs). These gases not only cause serious pollution to the surrounding environment but also pose a threat to human health and animal welfare. Ammonia and hydrogen sulfide have strong pungent odors, and long-term exposure can lead to problems such as respiratory diseases and conjunctivitis, and at the same time have an indirect impact on the ozone layer and acid rain formation in the atmospheric environment.

[0003] In traditional waste gas treatment technologies, the speed of waste gas passing through the filtering component is slow, resulting in low overall treatment efficiency and unable to meet the requirements of large-scale farms or high-concentration waste gas emission scenarios. Summary of the Invention

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] As Figures 1 to 6 shown:

[0038] Embodiment 1: The present invention provides a waste gas deodorization device for a breeding farm, including:

[0039] A gas introduction mechanism 1, including an intake pipe assembly 11 and an acceleration component 12 arranged on one side of the intake pipe assembly 11;

[0040] A filtering mechanism 2, including a filter cylinder assembly 21, an air inlet 22 arranged outside the filter cylinder assembly 21, and a filtering component 23 installed inside the filter cylinder assembly 21;

[0041] The intake pipe assembly 11 and the air inlet 22 are in communication with each other.

[0042] As can be seen from the above, after the waste gas is introduced through the intake pipe assembly 11, the acceleration component 12 works to introduce external gas and accelerate the flow of the gas in the intake pipe assembly 11. The external gas will attract the waste gas in the intake pipe assembly 11 under high-speed flow, thereby improving the deodorization efficiency;

[0043] The introduced waste gas enters the filter cylinder assembly 21 through the air inlet 22. Inside the filter cylinder assembly 21, the particulate matter and pollutants in the waste gas are captured and removed through the filtering component 23;

[0044] The filtered waste gas is discharged from the outlet of the filter cylinder assembly 21 and enters the subsequent treatment equipment.

[0045] As Figures 1 to 5 shown:

[0046] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the filter cylinder assembly 21 includes a filter cylinder body 211, a filter cylinder cover 212 is arranged on the upper side of the filter cylinder body 211, and a waste discharge port 213 is arranged at the bottom of the filter cylinder body 211;

[0047] A support frame 214 is also fixedly installed inside the filter cylinder body 211, a limit bearing 215 is arranged on the upper side of the support frame 214, and an exhaust port 216 and a water inlet 217 are fixedly connected to the upper side of the filter cylinder cover 212;

[0048] The air inlet 22 is fixedly installed on the outside of the filter cylinder body 211.

[0049] Specifically, the filtering component 23 includes a partition frame 231. Filter plates 232 are fixedly connected to both sides of the partition frame 231. A group of filter boxes 233 are also fixedly connected to the upper side of the partition frame 231. Activated carbon is provided inside the group of filter boxes 233, and filter holes are provided at the bottom of the filter boxes 233.

[0050] Specifically, a rotating rod 234 is also fixedly connected to the middle position on the upper side of the partition frame 231, and a first gear 235 is fixedly connected to the end of the rotating rod 234;

[0051] A driving component 24 is further provided on the upper side of the filter cylinder component 21. The driving component 24 includes a motor 241, and a second gear 242 is fixedly connected to the output end of the motor 241.

[0052] Specifically, the rotating rod 234 is installed on the filter cylinder cover 212 through a limit bearing. The motor 241 is fixedly installed on the upper side of the filter cylinder cover 212. The second gear 242 and the first gear 235 are meshed with each other, and the limit bearing 215 is installed on the bottom of the partition frame 231 in a limited manner.

[0053] As can be seen from the above, when the waste gas containing pollutants enters the filter cylinder body 211 through the air inlet 22 at a certain speed, the filter plates 232 will intercept the larger particles in the waste gas, causing them to fall and be discharged from the waste discharge port 213. After the other waste gas enters the filter boxes 233, the smaller particles in the waste gas will be intercepted by the activated carbon. At the same time, the filtered waste gas will be discharged from the exhaust port 216 and collected;

[0054] Although the waste gas entering the filter cylinder body 211 has a certain speed, in order to prevent the waste gas from moving downward in the filter cylinder body 211, a heating device can be provided in the filter cylinder body 211 to accelerate the upward movement of the waste gas and prevent the waste gas from overflowing from the waste discharge port 213;

[0055] Controlling the motor 241 to work can cause the second gear 242 to drive the first gear 235 to rotate. The rotation of the first gear 235 can cause the rotating rod 234 to drive the partition frame 231 to rotate. The rotation of the partition frame 231 can move the used filter plates 232 and filter boxes 233 to the other side. Connect the external water source to the water inlet 217. After introducing water through the water inlet 217, the activated carbon in the filter boxes 233 can be rinsed, so that the dust and particulate matter attached to the activated carbon are separated and fall with the waste water and are discharged and collected from the waste discharge port 213. After the activated carbon is cleaned and drained, it can be conveniently recycled next time.

[0056] As Figure 6 shown:

[0057] Embodiment 3: This embodiment is basically the same as the previous embodiment, except that the intake pipe assembly 11 includes an intake pipe body 111, and a gas acceleration pipe 112 is provided on the upper side of the intake pipe body 111;

[0058] The speed increasing component 12 includes a blower 121, and a connecting hose 122 is fixedly connected to one side of the blower 121.

[0059] Specifically, the lower ends of the connecting hose 122 and the gas speed increasing pipe 112 are fixedly connected by bolts.

[0060] Specifically, the end of the air inlet pipe body 111 is also fixedly connected with an extension pipe 113 through a flange. An air suction port 114 is arranged on the outer side of the extension pipe 113. A negative pressure blower is arranged at the end of the air suction port 114, and the air suction ports 114 lead to each breeding room respectively.

[0061] Specifically, an air quality sensor and a single-chip microcomputer are also fixedly connected to the end of the air suction port 114. The air quality sensor, the negative pressure blower, and the blower 121 are all electrically connected to the single-chip microcomputer. The model of the air quality sensor is FST100 - 2105;

[0062] The air quality sensor monitors the gas concentration parameters in the breeding room in real time and transmits the data to the single-chip microcomputer; when any gas concentration parameter exceeds the preset threshold, the single-chip microcomputer controls through signal output:

[0063] Start the negative pressure blower, and inhale the waste gas into the pipeline through the air suction port 114;

[0064] Synchronously start the blower 121 to generate negative pressure in the gas speed increasing pipe 112, thereby driving the waste gas in the extension pipe 113 to flow;

[0065] Until the gas concentration parameters in the breeding room return to the normal range, the single-chip microcomputer sends a signal to turn off the negative pressure blower and the blower 121.

[0066] As can be seen from the above, during operation, when the air quality sensor detects that the gas concentration parameters in the breeding room exceed the preset threshold, the single-chip microcomputer controls the negative pressure blower to start, and then cooperates with the negative pressure blower through the air suction port 114 on the outer side of the extension pipe 113 to inhale the waste gas in each breeding room into the pipeline; at the same time, the single-chip microcomputer controls the blower 121 to work, so that the air in the connecting hose 122 flows rapidly, thereby driving the waste gas in the extension pipe 113 to flow efficiently to the filtering mechanism for treatment;

[0067] After the treatment is completed, when the gas concentration parameters in the breeding room return to the normal range, the single-chip microcomputer controls to turn off the negative pressure blower and the blower 121, realizing an automatic and efficient waste gas deodorization process.
