[0031] An air inlet 309 is provided at one end of the liquid reservoir 303 close to the first air pipe 6, a plurality of water outlets 3010 are provided on the inner wall of one end of the liquid reservoir 303 close to the base 1, an air diffusion pipe 3011 is provided in the inner cavity of the liquid reservoir 303 close to the water outlet 3010, an activated carbon filter 3012 is provided at one end of the liquid reservoir 303 away from the air inlet 309, a second air pipe 3013 is provided between the activated carbon filter 3012 and the second fan 308, and a third air pipe 3014 is provided at one end of the activated carbon filter 3012 away from the liquid reservoir 303.

[0032] Through the above technical solution, when it is necessary to deodorize the odorous gas in the fermentation tank 2, firstly, water and deodorant are poured into the water tank 304 and the deodorant tank 305 respectively, and then the mixing ratio of water and deodorant is adjusted by the liquid filling structure 306. After the adjustment is completed, the mixed solution is introduced into the liquid storage tank 303 by using the liquid filling structure 306 again. After the introduction is completed, the liquid filling structure 306 is closed, and then the odorous gas in the fermentation tank 2 is introduced into the air inlet 309 through the first air delivery pipe 6, and then the odorous gas is introduced into the diffuser 3011 by using the air inlet 309, and the odorous gas is evenly dispersed into the mixed solution by the diffuser 3011, and the odorous gas is removed by using the mixed solution. The gas is preliminarily treated, and then the odorous gas that has been preliminarily treated moves toward the direction of the cover 307, and then the second fan 308 is used to introduce the odorous gas in the cover 307 into the second gas pipe 3013, and the second gas pipe 3013 introduces the odorous gas into the activated carbon filter 3012, and the activated carbon filter 3012 is used to adsorb the odorous gas again to prevent other odorous particles from remaining in the odorous gas, and then the activated carbon filter 3012 introduces the treated gas into the outlet pipe 8 through the third gas pipe 3014, and the water outlet 3010 is convenient for the staff to discharge the failed mixed solution in the liquid storage tank 303 when the mixed solution fails.

[0033] like Figure 6 and Figure 7 As shown, the liquid filling structure 306 includes a mechanism base 30601, a display screen 30602 is provided on one end surface of the mechanism base 30601, a metering pump 30603 is provided inside the mechanism base 30601, a water pipe 30604 is provided at one end of the metering pump 30603 close to the water storage tank 304, and a liquid infusion tube 30605 is provided at one end of the metering pump 30603 close to the agent storage tank 305;

[0034] A guide tube 30606 is provided at one end of the metering pump 30603 away from the infusion tube 30605, a proportional adjustment ring 30607 is provided at one end of the metering pump 30603 close to the guide tube 30606, a first swirl 30608 and a second swirl 30609 are provided at both ends of the guide tube 30606 close to and away from the metering pump 30603, respectively, and a spiral fan blade 30610 is provided between the first swirl 30608 and the second swirl 30609.

[0035] According to the above technical solution, when the mixing ratio of water and deodorant needs to be adjusted, first rotate the ratio adjustment ring 30607, and the ratio adjustment ring 30607 uses the metering pump 30603 to adjust the mixing ratio of water and deodorant. At the same time, the mixing ratio coefficient will be displayed on the display screen 30602. After adjusting to the specified ratio, use the display screen 30602 to turn on the metering pump 30603, and the water and deodorant in the water tank 304 and the agent tank 305 enter the metering pump 30603 along the water pipe 30604 and the infusion pipe 30605 respectively, and then enter the guide tube 30606 through the metering pump 30603. The first swirl 30608 in the guide tube 30606 causes the water and deodorant to form a vortex, and then the water and deodorant The vortex formed by the deodorant impacts the spiral fan blade 30610 and is broken up by the spiral fan blade 30610. At the same time, after being impacted, the spiral fan blade 30610 starts to rotate, mixes and stirs the broken up water and deodorant to form a mixed liquid, and then the spiral fan blade 30610 guides the mixed liquid into the second vortex 30609. Since the vortex of the second vortex 30609 is opposite to that of the first vortex 30608, when the mixed liquid reaches the second vortex 30609, it will be temporarily stagnant due to the opposite vortexes. At this time, the new mixed liquid at the spiral fan blade 30610 will impact the temporarily stagnant mixed liquid, so as to further mix the mixed liquid evenly. Finally, the mixed mixed liquid passes through the second vortex 30609 and falls into the liquid storage tank 303.

[0036] Working principle:

[0037] The present invention first opens the feed port 4, then puts the wheat straw into the fermentation tank 2 through the feed port 4, then closes the feed port 4, starts the fermentation tank 2, ferments the wheat straw, then opens the uniaxial baffle 9, delivers the activated carbon into the deodorization mechanism 3, then regularly starts the first fan 5 and the deodorization mechanism 3, the first fan 5 extracts the odorous gas in the fermentation tank 2 from the fermentation tank 2, and then uses the first gas supply pipe 6 to deliver the odorous gas into the deodorization mechanism 3, and uses the deodorization mechanism 3 to deodorize the odorous gas, and then the deodorization mechanism 3 delivers the deodorized gas into the filter device 7, and uses the filter device 7 to filter the gas again, and then the filter device 7 discharges the gas to the designated position through the outlet pipe 8, so that the odorous gas generated by the fermentation can be effectively treated during the fermentation process, so as to keep the environment clean and the staff physically and mentally healthy.

[0038] When it is necessary to deodorize the odorous gas in the fermentation tank 2, firstly, water and deodorant are poured into the water tank 304 and the deodorant tank 305 respectively, and then the mixing ratio of water and deodorant is adjusted by the liquid filling structure 306. After the adjustment is completed, the mixed solution is introduced into the liquid storage tank 303 by the liquid filling structure 306 again. After the introduction is completed, the liquid filling structure 306 is closed, and then the odorous gas in the fermentation tank 2 is introduced into the air inlet 309 through the first air delivery pipe 6, and then the odorous gas is introduced into the diffuser 3011 by the air inlet 309, and the odorous gas is evenly dispersed into the mixed solution by the diffuser 3011, and the odorous gas is deodorized by the mixed solution. The odorous gas is initially treated and then moves toward the sealing cover 307. The second fan 308 is then used to introduce the odorous gas in the sealing cover 307 into the second gas pipe 3013. The second gas pipe 3013 introduces the odorous gas into the activated carbon filter 3012. The activated carbon filter 3012 is used to adsorb the odorous gas again to prevent other odorous particles from remaining in the odorous gas. The activated carbon filter 3012 then introduces the treated gas into the gas outlet pipe 8 through the third gas pipe 3014. The water outlet 3010 is convenient for the staff to discharge the failed mixed solution in the liquid storage tank 303 when the mixed solution fails.

[0039] When the mixing ratio of water and deodorant needs to be adjusted, first rotate the ratio adjustment ring 30607, and the ratio adjustment ring 30607 uses the metering pump 30603 to adjust the mixing ratio of water and deodorant. At the same time, the mixing ratio coefficient will be displayed on the display screen 30602. After adjusting to the specified ratio, use the display screen 30602 to turn on the metering pump 30603, and the water and deodorant in the water tank 304 and the agent tank 305 enter the metering pump 30603 along the water pipe 30604 and the infusion pipe 30605 respectively, and then enter the guide tube 30606 through the metering pump 30603. The first swirl pattern 30608 in the guide tube 30606 causes the water and the deodorant to form a vortex, and then the water and the deodorant form a vortex. The vortex impacts the spiral blade 30610 and is broken up by the spiral blade 30610. At the same time, after being impacted, the spiral blade 30610 starts to rotate, mixes and stirs the broken up water and deodorant to form a mixed liquid, and then the spiral blade 30610 introduces the mixed liquid into the second vortex 30609. Since the vortices of the second vortex 30609 and the first vortex 30608 are opposite to each other, when the mixed liquid reaches the second vortex 30609, it will be temporarily stagnant due to the opposite vortices. At this time, the new mixed liquid at the spiral blade 30610 will impact the temporarily stagnant mixed liquid, so as to further mix the mixed liquid evenly. Finally, the mixed mixed liquid passes through the second vortex 30609 and falls into the liquid storage tank 303.

[0040] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
