Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0059] Example 1

[0060] As attached Figure 1 -Appendix Figure 3 As shown, this embodiment discloses a pigsty deodorization system for treating odors in pigsty 1, which mainly includes pigsty 1 and deodorization device 2. In use, when deodorization device 2 is activated, the deodorizing agent emitter 23 in deodorization device 2 releases deodorizing agent, allowing the deodorizing agent to be present in the manure ditch 14. However, the deodorizing agent usually cannot cover the entire manure ditch 14. External wind enters the manure ditch 14 of pigsty 1 from the air inlet 16, blowing odors far from the deodorizing agent into the area covered by the deodorizing agent, allowing the deodorizing agent to fully contact the odor. This design improves the deodorization effect of deodorization device 2.

[0061] The specific structure of the pigsty deodorization system is as follows: It includes a pigsty 1, with a manure ditch 14 located near its bottom. Inside the pigsty 1 is a pig pen 11, located upstream of the manure ditch 14 and connected to it. An deodorizing device 2 is installed on the inner wall of the manure ditch 14, containing a deodorizing agent dispensing element 23. An air inlet 16 is located on the side of the pigsty 1 furthest from the deodorizing device 2, and is connected to the manure ditch 14. Compared to existing technologies, this invention effectively reduces the ammonia concentration inside the pigsty 1, thereby achieving the purpose of treating the odor in the pigsty 1 and reducing feeding costs to a certain extent, demonstrating high practicality.

[0062] In a specific application scenario, as shown in the appendix Figure 2 and appendix Figure 3 As shown, the deodorizing device 2 includes a deodorizing agent flow control component 21 and a deodorizing agent storage hopper 22.

The inlet end of the deodorizing agent delivery pipeline is located above the deodorizing agent flow control component 21. The deodorizing agent storage hopper 22 is provided at the inlet end of the deodorizing agent delivery pipeline. This design facilitates timely replenishment of deodorizing agent by staff to the deodorizing device 2.

[0063] Furthermore, the deodorant emitting component 23 is a deodorant evaporating component; wherein, under the action of the deodorant flow control component 21, the deodorant evaporating component can control the speed of its deodorant delivery, thereby adjusting the wettability of the deodorant evaporating component; the deodorant evaporating component can increase the contact area between the deodorant and the odor; in addition, the deodorant evaporating component is usually made of porous and easily absorbent materials.

[0064] Furthermore, the deodorizing agent in the deodorizing device 2 can be a microbial agent, an organic acid reagent, or an oxidizing agent; the user can choose a suitable substance as a deodorizing agent and add it to the deodorizing agent storage hopper 22 according to their current needs, and the relevant details will not be elaborated here.

[0065] Furthermore, the deodorizing agent delivery pipeline can be a PVC transmission pipeline; wherein, the PVC transmission pipeline facilitates the replenishment and delivery of the deodorizing agent; at the same time, it also facilitates the adjustment of the deodorizing agent by the deodorizing agent flow control component 21.

[0066] In a specific application scenario, as shown in the appendix Figure 3 As shown, the pig-raising room 11 mainly includes pig pens 111 and slatted floors 112; the number of pig pens 111 is several, with attached... Figure 3 The diagram shows three pig pens 111. The pig pen 11 has three sides consisting of pig pens 111, with the remaining side being the wall of the pigsty 1. The current pig pen 11 is rectangular, collectively enclosing a space for raising pigs. Of course, users can set up more pig pens 111 according to their needs to manage different pigs in separate areas; the details of this will not be elaborated here. Typically, the pigsty 1 has one entrance / exit (not marked in the diagram). To the left of this entrance / exit is a corridor 12, which is located near and away from the entrance / exit of the pigsty 1. The entrance is flanked by passageways 13. The passageways 12 and 13 are located outside the pig pen 11. This design facilitates the installation of the deodorization device 2 and also makes it easier for staff to manage and feed the pigs. The pig pen 111 is connected to a slatted floor 112, which covers the bottom area of ​​the pig pen 11. The top of the slatted floor 112 has several slatted holes (not marked in the figure), and the slatted floor 112 is connected to the manure ditch 14.

During use, the deodorizing agent flow control component 21 can deliver a corresponding amount of deodorizing agent to the deodorizing agent evaporator based on the data monitored by the odor detector 4. This design can improve the odor treatment effect and reduce the waste of deodorizing agent to a certain extent.

[0070] Furthermore, the odor monitor 4 can be an ammonia probe monitor; wherein, the ammonia probe monitor can accurately monitor the concentration of ammonia in the manure ditch 14.

[0071] Example 3

[0072] As attached Figure 1 -Appendix Figure 3As shown, this embodiment discloses a pigsty deodorization system that increases the contact area between the deodorizing agent and the odor. In addition to the components in the aforementioned embodiment 2, it also includes an exhaust device 3, which can carry more of the odor in the manure ditch 14 to the area covered by the deodorizing agent. This design increases the contact area between the deodorizing agent and the odor, thereby achieving the capture and removal of the odor.

[0073] In a specific application scenario, the exhaust device 3 is located on the side of the pig house 1 close to the deodorizing device 2, and the exhaust device 3 is located on the side of the deodorizing device 2 away from the air inlet 16. The exhaust device 3 is used to guide the odor in the manure ditch 14 to the location of the deodorizing agent emitter 23.

[0074] In a specific application scenario, as shown in the appendix Figure 3 As shown, the ventilation device 3 mainly includes an exhaust fan 31 and an exhaust duct 32. The exhaust fan 31 is installed on the outer wall of the pigsty 1. The exhaust duct 32 runs through the interior of the pigsty 1. The exhaust duct 32 has an air inlet and an air outlet. The air outlet of the exhaust duct 32 is connected to the air outlet of the exhaust fan 31, and the air inlet of the exhaust duct 32 is located inside the manure ditch 14. In use, starting the exhaust fan 31 can bring more odorous gas that is far away from the deodorizing agent to the area covered by the deodorizing agent, thereby improving the treatment effect of the manure ditch 14 in this embodiment.

[0075] Furthermore, as shown in the appendix Figure 3 As shown, the exhaust device 3 is also equipped with an air guide plate 33, which is connected to the air inlet of the air duct 32. This design can more evenly concentrate the odor in the manure ditch 14 to the area covered by the deodorizing agent. In addition, there is a certain distance between the air guide plate 33 and the bottom wall of the manure ditch 14.

[0076] In a specific application scenario, as shown in the appendix Figure 2 and appendix Figure 3 As shown, an air inlet pipe 17 is installed inside the pig house 1. The air inlet pipe 17 has an air inlet side and an air outlet side. The air inlet side of the air inlet pipe 17 is located at the air inlet 16 of the pig house 1, and the air outlet side of the air inlet pipe 17 is located inside the manure ditch 14. There is a certain distance between the air outlet side of the air inlet pipe 17 and the bottom wall of the manure ditch 14.

[0077] Example 4

[0078] As attached Figure 1 and appendix Figure 3 As shown, this embodiment discloses a pigsty deodorization system to enhance the working performance of the aforementioned embodiment 3. In addition to the components in the aforementioned embodiment 3, it also includes a manure cleaning component 5, which can clean the manure ditch 14 and then discharge the manure and urine in the manure ditch 14 from the pigsty 1, thereby improving the living environment of the pigs.

[0079] In a specific application scenario, as shown in the appendix Figure 1 As shown, a fecal and urine discharge outlet 15 is provided on one side of the fecal ditch 14; a fecal and urine cleaning component 5 is provided on the inner wall of the fecal ditch 14, as shown in the attached figure. Figure 3 As shown, the fecal and urine cleaning component 5 is located on the side opposite to the fecal and urine outlet 15. Normally, the inner wall of the fecal ditch 14 is equipped with a fecal and urine detector (not shown in the figure). The fecal and urine detector is electrically connected to the fecal and urine cleaning component 5. When the fecal and urine detector detects that the fecal and urine in the current fecal ditch 14 has reached a preset range, it can send a command to the fecal and urine cleaning component 5 to start working. This can prevent fecal and urine from accumulating inside the fecal ditch 14 for a long time.

[0080] Example 5

In addition to the components in the aforementioned embodiment 1, it also includes a ramp 6, a step 7, and a door panel 8. The ramp 6 is located on the side of the manure and urine discharge outlet 15, which improves the efficiency of manure and urine discharge to a certain extent. The step 7 is located on one side of the entrance and exit of the pigsty 1. This design facilitates the entry of staff into the pigsty 1. At the same time, when staff do not want to stay inside the pigsty 1, they can sit on the step 7 to rest. When an emergency occurs inside the pigsty 1, staff can also react quickly. The door panel 8 is located at the entrance and exit of the pigsty 1. When staff leave work, they can lock the door panel 8 to prevent others from entering the pigsty 1.

[0082] In addition, the top of pigsty 1 is a rain cover structure, and the area it covers is larger than the area occupied by the main body of pigsty 1, so rainwater is not easy to enter pigsty 1 when it rains.

[0083] This embodiment also considers a situation, and the specific solution is as follows: the bottom wall of the manure ditch 14 is a sloping structure; wherein, the height of the bottom wall of the manure ditch 14 near the manure outlet 15 is lower than the height of the bottom wall of the manure ditch 14 away from the manure outlet 15. This design can further improve the efficiency of manure discharge.

[0084] This embodiment also considers another situation, and the specific solution is as follows: the outer wall of the pigsty 1 is provided with ventilation openings 18, which can improve the freshness of the air inside the pigsty 1.

[0085] The following description, using an optional embodiment, illustrates the content involved in the above embodiments.

[0086] Example 6

[0087] This embodiment discloses a pigsty deodorization system. The following is the complete process of implementing any of the aforementioned embodiments: The test was conducted in a 650-head standardized pigsty (1) fattening unit, using dry manure cleaning. During the test, the pigs were 130 days old. Three sets of deodorizing agent dispensers 23, each 15cm high and 10cm thick, spanning the entire pigpen 111, were suspended below the slatted floor 112. During the test, the deodorizing agent in the first deodorizing device 2 was a lactic acid bacteria fermentation liquid with a fermentation pH of 3.2-3.5; the deodorizing agent in the second deodorizing device 2 was an acetic acid organic solvent at a concentration of 1%; and the deodorizing agent in the third deodorizing device 2 was a 2000ppm chlorine dioxide oxidant. Pigsty 1 operated normally. During this process, the deodorizing agent replenishment flow rate was set to 10ml / min. The ammonia concentration and odor control effects during the test are shown in the attached figure. Figure 4 and appendix Figure 5 As shown.

[0088] It should be noted that, in addition to ammonia, hydrogen sulfide gas is usually also produced in the manure ditch 14. Both ammonia and hydrogen sulfide gas are odorous gases in the manure ditch 14. In addition, the odor detector 4 in the aforementioned Examples 1-5 also has the function of monitoring hydrogen sulfide gas.

[0089] In the control group, the ammonia concentration was maintained between 15-19 ppm, with an average concentration of 16.4 ppm; in the experimental group, the ammonia concentration was maintained between 9-14 ppm, with an average concentration of 11 ppm. After adding deodorization device 2, the ammonia removal rate reached 32.8%. The dimensionless odor value of the control group was between 300-365, with an average of 324.9, while the dimensionless odor value of the experimental group was between 233-279, with an average of 259.3, resulting in an average removal rate of 20.2%. The dimensionless odor value is a numerical value used to measure odor intensity; it has no specific unit and is simply a number used to compare odor strength. A higher value indicates a stronger odor, and a lower value indicates a weaker odor. Using this embodiment, the odor from manure ditch 14 was effectively removed. It is low-cost and easy to maintain, and can well meet the user's needs without changing the existing main structure of pigsty 1.
