[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1-3 , the utility model provides an embodiment: an odor absorption device for sewage treatment, comprising an air intake pipe 1 and a treatment chamber 4, a delivery pipe 3 is fixedly connected to the adjacent side of the air intake pipe 1 and the treatment chamber 4, a collecting head 2 is fixedly connected to the bottom side of the air intake pipe 1, a cover body 5 is threadedly connected to the top of the air intake pipe 1, one end of a frame body 6 located at the bottom side of the cover body 5 is fixedly connected to the bottom side of the cover body 5, and a plurality of filter plates 7 are fixedly connected to the other end of the frame body 6, an outer wall of an air intake fan 8 located at the bottom side of the filter plate 7 is installed on the inner wall of the air intake pipe 1, an input end of the air intake fan 8 is located at the bottom side of the air intake pipe 1, an output end of the delivery pipe 3 is located at the inner left end of the treatment chamber 4, and a power turbine 13 is arranged inside the air outlet pipe 9 fixedly connected to the output end, a turntable 10 is rotatably connected to the top side of the air intake pipe 1, and a plurality of spray heads are installed on the bottom side of the turntable 10;

[0025] Specifically, a sealing ring is connected between the cover 5 and the air inlet pipe 1 to prevent gas leakage. The odorous gas generated in the sewage treatment will enter the air inlet pipe 1 along the collecting head 2 under the attraction of the air inlet fan 8. The collecting head 2 can expand the gas contact area on the bottom side and allow the gas to enter the air inlet pipe 1 along the inclined surface of the inner wall. Through the primary filtering treatment of the filter plate 7, a certain odor is removed. The filter plate 7 is made of activated carbon and can effectively absorb odorous substances in the gas. The gas will enter the outlet pipe 9 along the delivery pipe 3 connected to the air inlet pipe 1, and then enter the treatment chamber 4 through the outlet pipe 9. By rotating the cover 5, the cover 5 can be removed from the air inlet pipe 1, and then the cover 5 together with the frame 6 and the filter plate 7 on the frame 6 can be removed, and then the filter plate 7 can be cleaned and replaced. Multiple spray heads are externally connected with a feed pipe for providing chemical liquid for spraying to the spray head for removing odor. The spray head sprays in an oblique direction to expand the spraying area.

[0026] Reference Figure 3 , a partition is fixedly connected to the bottom side of the inner wall of the processing chamber 4, the air outlet pipe 9 is located on the left side of the partition, and the rotating disk 10 is located on the right side of the partition;

[0027] Specifically, there is a certain distance between the top side of the partition and the top side of the inner wall of the processing chamber 4, which serves as a flow path for the gas and divides the space in the processing chamber 4 into two areas.

[0028] Reference Figure 3 and Figure 4 The bottom sides of the two pulleys 12 located on the top side of the processing chamber 4 are fixedly connected with a rotating rod 11. The bottom end of the left rotating rod 11 penetrates the top side of the inner wall of the outlet pipe 9 and is rotatably connected to the rotating rod 11. The bottom side of the left rotating rod 11 is fixedly connected to the top side of the power turbine 13. The bottom end of the right rotating rod 11 penetrates the top side of the inner wall of the inlet pipe 1 and is fixedly connected to the middle end of the top side of the turntable 10.

[0029] Specifically, when the gas passes through the power turbine 13 in the outlet pipe 9, it will drive the power turbine 13 to rotate, and drive the rotating rod 11 connected to the pulley 12 to rotate. The rotating pulley 12 will use the belt to drive another pulley 12, so that the other pulley 12 drives the bottom side including another rotating rod 11 and the turntable 10 to rotate, so that the turntable 10 drives the spray head to rotate and spray, expand the spray range, and roll up the airflow in the area on the right side of the partition, so that the liquid medicine is easier to mix with the gas, and the chemical components in the liquid medicine react with the odorous substances in the air to remove the odor. The process uses the flow of airflow to generate power throughout the process, and uses micro-power drive to reduce the deployment of redundant electric power sources, thereby reducing energy consumption and greatly reducing the cost of sewage gas treatment.

[0030] Reference Figure 5The right side of the processing chamber 4 is fixedly connected to an exhaust pipe 16 and has a spiral passage inside;

[0031] Specifically, the spiral channel and partition in the exhaust are used to delay and slow down the gas flow in the processing chamber 4, so that the gas that needs to remove the odor can stay in the area on the right side of the partition for a slightly longer time, so that the gas can fully contact with the chemical agent to remove the odor.

[0032] Reference Figure 3 The cooling assembly includes a water cooling device 14 installed on the front side of the outer wall of the processing chamber 4, a cooling pipe is installed on the rear side of the water cooling device 14, the cooling pipe is located on the outer periphery of the outlet pipe 9, and a waste pipe 15 is arranged on the bottom side of the cooling pipe, and the output end of the waste pipe 15 passes through the bottom side of the outer wall of the processing chamber 4;

[0033] Specifically, a waste flow path penetrating the partition and connected to the waste pipe 15 is provided in the right area of ​​the partition so as to discharge the chemical liquid after the reaction from the waste pipe 15. The cooling pipe surrounds the gas outlet pipe 9 so that the gas discharged from the gas outlet pipe 9 into the processing chamber 4 contacts the low-temperature cooling pipe, so that the moisture in the gas is condensed and liquefied, thereby reducing the moisture in the gas, improving the accuracy of subsequent chemical treatment, and avoiding the influence of the moisture in the gas on the chemical agent.

[0034] Working principle: The odorous gas generated in sewage treatment will be attracted by the air intake fan 8, enter the air intake pipe 1 along the collecting head 2, and pass through the primary filtration treatment of the filter plate 7 to remove certain odors. Then the gas will enter the outlet pipe 9 along the delivery pipe 3 connected to the air intake pipe 1, and then enter the treatment chamber 4 through the outlet pipe 9. The gas then enters the right area of ​​the partition from the left area of ​​the partition in the treatment chamber 4 through the vacancy above the partition, and is sprayed by the spray head on the bottom side of the turntable 10 for secondary chemical treatment to further remove the odor. When the gas passes through the power turbine 13 in the outlet pipe 9, the gas will enter the treatment chamber 4 through the vacancy above the partition. When the power turbine 13 is in the position, it will drive the power turbine 13 to rotate, and drive the rotating rod 11 connected to the pulley 12 to rotate. The rotating pulley 12 will use the belt to drive another pulley 12, so that the other pulley 12 drives the components on the bottom side including another rotating rod 11 and the turntable 10 to rotate, so that the turntable 10 drives the spray head to rotate and spray medicine, expand the spraying range, and roll up the airflow in the area on the right side of the partition, so that the liquid medicine is easier to mix with the gas, so that the chemical components in the liquid medicine react with the odorous substances in the air to remove the odor, and finally discharge the gas through the exhaust pipe 16.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. 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.
