[0002] Wastewater treatment ponds release various odorous gases during operation, primarily including harmful gases such as hydrogen sulfide, ammonia, and volatile organic compounds. If these odorous gases are directly released into the atmosphere, they will pollute the surrounding environment and reduce air quality. Therefore, deodorization devices need to be installed during the operation of wastewater treatment ponds to purify the odors.

[0003] There has been some research on deodorization devices for sewage treatment ponds in the prior art.

Several activated carbon packing boxes are fixedly installed on the steel frame. Several ventilation holes are drilled in the wall panel of each activated carbon packing box.

[0004] Therefore, filling the activated carbon packing box with activated carbon granules facilitates the adsorption of odors. However, it is unavoidable that some activated carbon particles will accumulate, which reduces the contact area between the odor and the activated carbon particles, thus decreasing the adsorption efficiency.

[0026] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0027] Please refer to Figures 1-4 As shown, a deodorization device for a sewage treatment tank includes a treatment tank 1. An adsorption chamber 4 is provided on one side of the treatment tank 1 and is connected to the treatment tank 1. An activated carbon chamber 14 is provided inside the adsorption chamber 4 and is filled with activated carbon. A drive assembly is installed in the adsorption chamber 4. The output end of the drive assembly is connected to a rotating shaft 15 that penetrates into the activated carbon chamber 14. A stirring rod 16 is connected to the outer periphery of the rotating shaft 15.

[0028] In this invention, a rotating shaft 15 extending into the interior of the activated carbon chamber 14 and a stirring rod 16 connected to the outer periphery of the rotating shaft 15 are provided. The rotating shaft 15 and the stirring rod 16 are driven to rotate by a driving assembly, thereby stirring the activated carbon filled in the activated carbon chamber 14. This ensures that the activated carbon particles are always evenly distributed inside the activated carbon chamber 14 during the odor adsorption process, thus preventing the accumulation of activated carbon particles, increasing the contact area between the odor and the activated carbon particles, and improving the adsorption efficiency of the activated carbon for odor.

[0029] The drive assembly includes a rotary motor 6 and a first transmission component. The rotary motor 6 is connected to the activated carbon chamber 14; the first transmission component is a first gear 7, which is connected to the output end of the rotary motor 6 and is coaxially and fixedly connected to the rotating shaft 15.

[0030] The rotary motor 6 drives the rotating shaft 15 to rotate via the first gear 7. During the rotation of the rotating shaft 15, the stirring rod 16 stirs the activated carbon inside the activated carbon chamber 14, so that the activated carbon is evenly distributed inside the activated carbon chamber 14. This makes the operation convenient and improves the adsorption efficiency of odor.

[0031] Optionally, the side wall of the adsorption chamber 4 is provided with through holes 5, and the adsorption chamber 4 is connected to the spray chamber 3. The through holes 5 facilitate the discharge of odorous gas treated by activated carbon from the adsorption chamber 4.

[0032] Optionally, the adsorption chamber 4 has an open end, and the activated carbon chamber 14 has a feeding end. The open end of the adsorption chamber 4 and the feeding end of the activated carbon chamber 14 are positioned opposite each other. The open end of the adsorption chamber 4 is covered with a cover plate, which is detachably connected to the adsorption chamber 4. Specifically, the cover plate can be connected to the adsorption chamber 4 by snap-fit, hinge, or tenon joint. By opening the cover plate, the activated carbon inside the activated carbon chamber 14 can be replaced, which is convenient and improves the efficiency of odor treatment.

[0033] Please refer to Figures 1-4 As shown, in some embodiments, a spray chamber 3 is provided between the adsorption chamber 4 and the treatment tank 1. One side of the spray chamber 3 is connected to the treatment tank 1, and the other side of the spray chamber 3 is connected to the adsorption chamber 4. Spray liquid is added inside the spray chamber 3.

[0034] Specifically, the spray chamber 3 is provided with a first vent and a second vent. The spray chamber 3 is connected to the treatment tank 1 through the first vent and to the adsorption chamber 4 through the second vent.

[0035] The spray chamber 3 and adsorption chamber 4 are set up to perform primary deodorization of odor through the spray liquid in the spray chamber 3 and secondary deodorization of odor through the activated carbon in the activated carbon chamber 3, thus performing multiple treatments on the odor and improving the treatment effect.

[0036] Optionally, a spray pipe 9 is installed inside the spray chamber 3. One end of the spray pipe 9 extends into the spray liquid, and a rotary joint is rotatably connected to the end of the spray pipe 9 away from the spray liquid. A spray head 13 is fixedly connected to the end of the rotary joint away from the spray pipe 9, and the spray head 13 is connected to the spray pipe 9 through the rotary joint. A second transmission component is installed on the activated carbon chamber 14. The second transmission component is connected to the first gear 7 and is configured to drive the spray head to rotate. The rotary joint is an existing commercially available product and a pipe connection component well known to those skilled in the art, so it will not be described in detail here.

[0037] The second transmission component includes a second gear 8, a worm 12, and a worm wheel 10. The second gear 8 meshes with the first gear 7; the worm 12 is coaxially connected to the second gear 8, and the worm 12 extends into the interior of the spray chamber 3, and is rotatably connected to the spray chamber 3; the worm wheel 10 meshes with the worm 12, and the worm wheel 10 has a coaxially arranged worm wheel shaft, one end of which is fixedly connected to the spray head 13, and the other end of which is rotatably connected to the inner wall of the spray chamber 3 through a bearing to support the worm wheel 10.

[0038] Specifically, a water pump is installed inside the spray chamber 3, and the output end of the water pump is connected to the spray pipe 9. The water pump injects the spray liquid in the spray chamber 3 into the spray pipe 9, which facilitates the addition of spray liquid to the spray pipe 9.

[0039] In this embodiment, the odorous gas entering the spray chamber 3 from the treatment tank 1 rises upwards through the spray liquid and is distributed at the top of the spray chamber 3. At this time, the spray liquid in the spray chamber 3 deodorizes the odorous gas once. The water pump is started, and the spray liquid in the spray chamber 3 is injected into the spray pipe 9. The spray liquid in the spray pipe 9 flows through the rotary joint to the spray head 13. The rotary motor 6 drives the first gear 7 to rotate, the first gear 7 drives the second gear 8 to rotate, the second gear 8 drives the worm 12 to rotate, the worm 12 drives the worm wheel 10 to rotate, and the worm wheel 10 drives the spray head 13 to rotate synchronously with the rotary joint. During the rotation of the spray head 13, the spray liquid is sprayed out from the spray head 13 to deodorize the odorous gas at the top of the spray chamber 3 a second time. The rotation of the spray head 13 increases the spray radiation surface of the spray liquid, thereby increasing the contact area between the odorous gas and the spray liquid and improving the treatment effect of the odorous gas.

[0040] Please refer to Figure 1 and Figure 2 As shown, in some embodiments, a fan 2 is installed at the top of the treatment tank 1 near the spray chamber 3, and the output end of the fan 2 is connected to an air inlet pipe 11 that extends to the bottom of the spray chamber 3.

[0041] Optionally, the input end of the blower 2 is flush with the top of the treatment tank 1, increasing the contact area between the air inlet of the blower 2 and the treatment tank 1, thereby facilitating the rapid intake of odorous gas from the treatment tank 1 into the blower 2 and improving the odor treatment efficiency.

[0042] In this embodiment, the blower 2 is started, and the odor in the treatment tank 1 is drawn into the air inlet pipe 11 by the blower 2, and then discharged into the spray liquid through the air inlet pipe 11. The spray liquid comes into contact with the odor, completing the first deodorization of the odor. The treated and untreated odor rises from the spray liquid and is located at the top of the spray chamber 3. The blower 2 is set to improve the flow speed of the odor, thereby improving the odor treatment efficiency.

[0043] The working principle and usage process of this device are as follows: First, start the blower 2. The odor in the treatment tank 1 is drawn into the air inlet pipe 11 by the blower 2, and then discharged into the spray chamber 3 through the air inlet pipe 11. Some of the odor comes into contact with the spray liquid in the spray chamber 3 to complete one deodorization. At this time, the odor that has undergone one odor treatment and the odor that has not undergone one odor treatment rise from the spray liquid and are located at the top of the inside of the spray chamber 3.

[0044] The water pump is started, and the spray liquid in the spray chamber 3 is injected into the spray pipe 9. The spray liquid in the spray pipe 9 flows through the rotary joint to the spray head 13. The rotary motor 6 drives the first gear 7 to rotate, the first gear 7 drives the second gear 8 to rotate, the second gear 8 drives the worm 12 to rotate, the worm 12 drives the worm wheel 10 to rotate, and the worm wheel 10 drives the spray head 13 to rotate synchronously with the rotary joint. During the rotation of the spray head 13, the spray liquid is sprayed out from the spray head 13 to perform secondary deodorization of the odor at the top of the spray chamber 3.

[0045] The odorous gas after secondary odor treatment enters the activated carbon chamber 14, where the activated carbon adsorbs the odorous gas after secondary odor treatment, thereby achieving tertiary deodorization of the odorous gas. The odorous gas after tertiary deodorization is discharged through the through hole 5, thus completing the multiple treatment of odorous gas.
