As shown in Figures 1-3, the utility model provides a high-efficiency odor adsorption device, including an odor purification tower 2 and an adsorption tower 17. An air inlet 1 is arranged on the top of the odor purification tower 2, and a filter screen 21 is arranged inside the air inlet 1. Both sides of the filter screen 21 are connected to both sides of the inner wall of the air inlet 1 through a snap-fit structure. A purification layer 3 and an atomizing device are arranged in sequence below the air inlet 1. The atomizing device is arranged below the first partition plate 4. The atomizing device includes an infusion pipe 7 connected to an alkali liquid tank 9, a water pump 8 arranged on the infusion pipe 7, a water spray pipe 6 running through the odor purification tower 2, and an atomizing nozzle 5 arranged on the water spray pipe 6. A plurality of atomizing nozzles 5 are provided. The nozzles 5 are evenly arranged on the annular water spray pipe 6. The bottom end of the odor purification tower 2 is connected to the waste liquid tank 11 through the drain pipe 10. The exhaust pipe 12 is arranged inside the adsorption tower 17. One end of the exhaust pipe 12 passes through the adsorption tower 17 and the odor purification tower 2 in sequence and extends to the inside of the odor purification tower 2. An adsorption layer 18 is arranged inside the adsorption tower 17. The bottom of the adsorption tower 17 is fixedly connected to a motor 13. The output end of the motor 13 passes through the adsorption tower 17, extends to the inside of the adsorption tower 17 and is fixedly connected to a rotating column 14. Stirring rods 16 are fixedly connected on both sides of the rotating column 14. An exhaust port 20 is arranged on the top of the adsorption tower 17.

Filter cotton can also be provided on the filter screen 21. As the first step of the treatment process of the odor adsorption device, the filter screen 21 is installed on both sides of the inner wall of the air inlet 1 through a snap-on structure. The filter screen 21 can effectively block large particles of impurities visible to the naked eye in the odor, thereby effectively preventing large particles of impurities from entering the microbial layer and affecting the degradation efficiency and life of the microorganisms.

The purification layer 3 is a microbial layer, which is arranged on a porous first partition 4. By selecting a variety of high-concentration, high-activity effective microbial flora contained in nature, the odor is effectively degraded into carbon dioxide and water through the comprehensive action of the microbial flora without generating secondary pollution.

The alkali liquid tank 9 contains NaOH solution, the concentration of which is determined according to the amount and concentration of the odor. The pollutants in the odor react chemically with NaOH, and the reaction products flow into the waste liquid tank 11 along with the alkali washing liquid, thereby achieving the effect of removing some pollutants in the odor.

The water spray pipe 6 in the atomizing device is in a ring shape, and the liquid sprayed from the atomizing nozzle 5 is in a mist form, which is beneficial to increase the contact area between the liquid and the odor and improve the washing effect.

The adsorption layer 18 is an activated carbon layer, which is arranged on the porous second partition 15. The activated carbon layer is a honeycomb activated carbon. The activated carbon structure is a porous honeycomb with a developed pore structure, a large specific surface area, and a small fluid resistance. The adsorption performance is better than other activated carbons and has a good adsorption effect on odor treatment.

The number of stirring rods 16 is three or more. When the multiple stirring rods 16 are driven to rotate by the rotating rod 14, they will drive the activated carbon in various parts of the adsorption tower 17 to adsorb the odor, thereby accelerating the adsorption rate of the activated carbon on non-methane total hydrocarbons and other substances in the odor. The material of the stirring rods 16 is a lightweight alkali corrosion-resistant material, such as FPR material, to enhance the anti-corrosion effect.

The outside of the odor purification tower 2 and the adsorption tower 17 are both connected to the first movable door 221 and the second movable door 222 by hinge rotation.

The electrical output end of the switch 19 is electrically connected to the electrical input end of the motor 13, which can be conveniently used to turn on the motor 13 through the switch 19, bringing convenience to the user when using it.

In the utility model, by setting the filter 21, the purification layer 3, the atomizing device and the adsorption layer 18 for coordinated use, after the odor enters from the air inlet 1, it can first pass through the filter 21 to filter out large particle impurities in the odor, then the harmful substances in the odor are degraded by the microorganisms in the purification layer 3, and then the odor is purified by the neutralization reaction of the mist alkali solution and the odor, and finally the odor is adsorbed by the activated carbon, which solves the problem that the traditional odor treatment device cannot target and thoroughly treat various special components in the odor when treating the odor, ensures that various substances in the odor are targeted and meet the standards, and avoids the effect of polluting the ecological environment.

The working principle of the utility model is as follows: first, odor enters from the air inlet, and by setting a filter screen, large particles of impurities in the odor can be blocked to prevent solid impurities from entering from the air inlet. After the odor enters from the air inlet, it first passes through the purification layer to perform the first treatment on the odor, and the microbial flora reacts biochemically with the sulfur-containing substances in the odor. The odor after the first treatment is then treated for the second time with the misted alkali liquid sprayed by the atomizing device, and the alkali liquid reacts with the sulfide in the odor to neutralize, and the reaction waste liquid is collected into the waste liquid tank through the drain pipe, and the odor after the second treatment is sucked into the adsorption tower by the exhaust pipe, and the user starts the motor through the switch, and when the stirring rod is driven to rotate by the rotating rod, it will drive the activated carbon in the adsorption tower to adsorb the odor, thereby accelerating the adsorption speed of the activated carbon on the non-methane total hydrocarbons and other substances in the odor, and the gas after the treatment is discharged from the exhaust port.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
