[0001] This utility model relates to the field of waste gas recovery technology, specifically a waste gas recovery device for sewage treatment. Background Technology

[0002] Waste gas emissions are an unavoidable part of the wastewater treatment process. In particular, wastewater ponds, biochemical reaction ponds, and sludge treatment units generate a large amount of waste gas containing volatile organic compounds, hydrogen sulfide, ammonia, mercaptans, sulfides, and other malodorous substances. These waste gases not only pollute the environment but may also harm human health. Therefore, developing an efficient waste gas recovery device is of great practical significance.

[0003] However, some existing devices that use activated carbon to recover waste gas require frequent replacement of the activated carbon after adsorption saturation. The replacement cost of activated carbon is high, which increases the operating cost of enterprises. Moreover, the replaced activated carbon is usually disposed of as waste, which can easily cause environmental pollution and affect the health of surrounding residents. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4As shown, a waste gas recovery device for wastewater treatment includes a recovery shell 1. An air inlet 2 is located on one side of the recovery shell 1, and an exhaust outlet 3 is located on the other side. Waste gas can enter the interior of the recovery shell 1 through the air inlet 2 for filtration, and then exit through the exhaust outlet 3. An inspection door 4 is hinged to the opening of the recovery shell 1. The inspection door 4 consists of a handle and a temperature controller, facilitating normal operation by staff. A mounting frame 5 is fixedly connected to the inner wall of the recovery shell 1. Two filter shells 6 are installed inside the mounting frame 5, symmetrically positioned with respect to the centerline of the mounting frame 5. Activated carbon is stored inside the filter shells 6. The activated carbon effectively captures and fixes organic pollutant molecules on its surface, thereby effectively reducing the concentration of pollutants in the waste gas. The concentration of pollutants is reduced, the odor of the exhaust gas is decreased, and the air quality of the surrounding environment is improved, thereby reducing the impact of the exhaust gas on nearby residents. Support plates 7 are fixedly connected to both sides of the top of the filter shell 6. The bottom of the support plates 7 and the surface of the mounting frame 5 block each other, ensuring that the filter shell 6 can be stably installed on the mounting frame 5, providing a stable foundation for subsequent exhaust gas treatment. An immersion box 8 is fixedly connected to the inner wall of the recovery shell 1. The inner cavity of the immersion box 8 contains a nutrient solution containing microorganisms. Under this action, the filter shell 6 can be immersed in the inner cavity of the immersion box 8, allowing the nutrient solution containing microorganisms in the immersion box 8 to fully contact the activated carbon in the filter shell 6. This allows for the decomposition and metabolism of pollutants adsorbed on the surface of the activated carbon, effectively improving the adhesion of pollutants to the activated carbon surface. The improved pollutant removal efficiency allows the activated carbon inside the filter shell 6 to be reused, reducing the frequency of activated carbon replacement and minimizing equipment downtime caused by activated carbon replacement, thereby improving the operating efficiency of the device. The inner cavity of the soaking box 8 is equipped with a control mechanism 9, which works in conjunction with a temperature controller on the surface of the inspection door 4. With the cooperation of the control mechanism 9 and the inspection door 4, the temperature of the nutrient solution inside the soaking box 8 can be adjusted to maintain the optimal temperature range for microbial growth, thus maintaining the stability and activity of the microbial community and ensuring the long-term stable operation of the device. The inner wall at the top of the inner cavity of the recovery shell 1 is equipped with a switching mechanism 10, which works in conjunction with the filter shell 6. Under this action, the switching mechanism 10 is activated. By swapping the positions of the two filter housings 6, allowing them to be used alternately, the removal efficiency of pollutants from the exhaust gas is improved, ensuring continuous operation of the device and preventing purification interruptions. This maintains the device's consistently high purification performance. Limiting grooves 12 are formed on both sides of the filter housing 6, and limiting blocks 11 are fixedly connected to the inner wall of the mounting frame 5. The surface of the limiting blocks 11 slides against the inner wall of the limiting grooves 12. The cooperation of the limiting blocks 11 and the limiting grooves 12 guides the filter housing 6 during movement, making it more stable. A guide block 13 is provided inside the recovery shell 1. The guide block 13 blocks the incoming exhaust gas to the bottom of the filter housing 6 and directs it upwards along a specific path.This reduces fluctuations in purification effectiveness caused by uneven airflow distribution.

[0016] The control mechanism 9 includes a temperature sensor 91 installed on the inner wall of one side of the immersion box 8. The temperature sensor 91 can detect the temperature of the microbial nutrient solution in the immersion box 8. A heating tube 92 is installed on the inner wall at the bottom of the immersion box 8. The heating tube 92 can heat the microbial nutrient solution in the immersion box 8. The temperature sensor 91 works in conjunction with the temperature controller and heating tube 92 on the surface of the inspection door 4. Under this action, the operator can adjust the temperature of the microbial nutrient solution in the immersion box 8 to keep it within a relatively stable range, thereby ensuring that various microorganisms work synergistically in the community to continuously and efficiently purify the activated carbon. A liquid inlet 93 is provided on the other side of the immersion box 8. The surface of the liquid inlet 93 is fixedly connected to the inner wall of the recovery shell 1. The liquid inlet 93 is used to add microbial nutrient solution, reducing the problem of poor purification effect due to insufficient nutrient solution and ensuring the reliable operation of the device.

[0017] The switching mechanism 10 includes a hydraulic rod 101 disposed on the inner wall of the top of the inner cavity of the recovery shell 1. The output shaft of the hydraulic rod 101 is equipped with a servo motor 102. The output shaft of the servo motor 102 is fixedly connected to a connecting frame 103. The bottom of the connecting frame 103 is fixedly connected to the surface of the filter shell 6. Under this action, the hydraulic rod 101 is started, driving the servo motor 102, the connecting frame 103 and the filter shell 6 to move upward. At this time, the servo motor 102 is turned on to switch the positions of the two filter shells 6. Then, under the action of the hydraulic rod 101, the filter shell 6 is moved downward, so that the two filter shells 6 can be used alternately, ensuring that the device is always in a highly efficient purification state and that the device can operate continuously and stably.

[0018] Working principle: First, the exhaust gas enters the recovery shell 1 through the inlet 2. Under the action of the guide block 13, the exhaust gas is blocked to the bottom of the filter shell 6 and rises along a certain path, making full contact with the activated carbon inside the filter shell 6. This captures and fixes the organic pollutant molecules in the exhaust gas onto the surface of the activated carbon, effectively reducing the concentration of organic pollutants in the exhaust gas, alleviating odor, and improving the surrounding air quality. Subsequently, the treated exhaust gas is discharged from the exhaust port 3. When the purification efficiency of one filter shell 6 decreases due to blockage, the hydraulic rod 101 is activated to drive the servo motor 102, the connecting frame 103, and the filter shell 6 to move upward. Then, the servo motor 102 is turned on to switch the positions of the two filter shells 6. Under the action of the hydraulic rod 101, the filter shell 6 with low purification efficiency moves downward and is immersed in the soaking box 8. This allows the microbial nutrient solution in the cavity of the soaking box 8 to make full contact with the activated carbon inside the filter shell 6, decomposing and metabolizing the pollutants adsorbed on the surface of the activated carbon. This allows the activated carbon to be reused, reducing the replacement frequency, reducing equipment downtime, and improving the operating efficiency of the device.
