[0020] The following is a detailed description of the implementation of the utility model in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the utility model, but cannot be used to limit the scope of 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.

[0021] Combination Figure 1 and Figure 2As shown, an improved biological deodorization device includes a reactor body 1, in which a spraying area 2, a packing area 3, an air intake area 4 and a gas-water mixing area 5 are arranged; the spraying area 2 is used to spray the sewage in the aerobic pool on the packing area 3; the packing area 3 is a multi-layer arrangement for biological reaction of odor and sewage; the air intake area 4 is used to transport the odor to the gas-water mixing area 5; the gas-water mixing area 5 is used to mix the odor and the purified sewage; when the odor enters the gas-water mixing area 5 for preliminary filtration, the filtered gas passes through the multi-layer packing area 3 upward in turn for biological reaction and filtration, and at the same time, the spraying area 2 sprays the sewage in the aerobic pool on the packing area 3, and the spray water and gas after biological reaction and purification in the packing area 3 are contacted and filtered, and finally the filtered gas is discharged from the reactor body 1. Specifically, an innovatively designed biological deodorization device is intended to deal with odor problems more efficiently and environmentally friendly. The core structure of the device is the reactor body 1, and multiple functional areas are cleverly arranged inside to ensure that the odor is comprehensively and effectively treated. First, a spraying area 2 is provided in the reactor body 1. The function of the spraying area 2 is to spray the sewage in the aerobic pool evenly on the packing area 3. Such a design not only makes full use of the sewage resources in the aerobic pool, but also provides the necessary liquid medium for the subsequent biological reaction. Next is the packing area 3, which is the core area of ​​the entire deodorization device. The packing area 3 adopts a multi-layer design, and each layer is filled with specific biological fillers. These biological fillers have extremely high biological activity and can carry out efficient biological reactions on odor and sewage. Through the multi-layer structure of the packing area 3, the odor and sewage can undergo multiple biological reactions and filtrations at different levels, thereby greatly improving the deodorization effect. Below the packing area 3, an air intake area 4 is provided. The main function of the air intake area 4 is to transport the odor to be treated to the air-water mixing area 5 through a pipeline. In this way, the odor will be mixed with the purified sewage before entering the packing area 3, providing more favorable conditions for the subsequent biological reaction. The air-water mixing area 5 is located below the packing area 3, which is the key area for mixing the odor and the purified sewage. When the odor enters the gas-water mixing area 5, it will first be initially filtered to remove large particles of impurities. Then, the filtered gas passes through the multi-layer packing area 3 in turn, and fully contacts and reacts with the sewage sprayed on the packing. Under the biological action of the packing area 3, the harmful substances in the odor are gradually decomposed and transformed, and the sewage is further purified. Finally, the spray water and gas that have been purified by the biological reaction in the packing area 3 will be contacted and filtered again. In this process, the spray water can effectively adsorb and filter the residual harmful substances in the gas, ensuring that the final discharged gas meets the environmental protection standards. The entire deodorization process realizes the recycling of resources and zero emission to the environment, and has a high environmental value.

[0022] Combination Figure 1 and Figure 2 As shown, the spraying area 2 includes a water inlet pipe 21 arranged above the packing area 3, a plurality of nozzles 22 are arranged on the water inlet pipe 21, and a water pump 23 is connected to the water inlet pipe 21. Specifically, the spraying area 2 mainly includes a water inlet pipe 21 arranged above the packing area 3. This water inlet pipe 21 is carefully arranged to ensure that it can evenly and stably transport sewage to the nozzle 22. The material selection of the water inlet pipe 21 needs to consider its corrosion resistance and pressure resistance to ensure long-term stable operation. On the water inlet pipe 21, there are a plurality of nozzles 22. The arrangement and number of these nozzles 22 are accurately calculated to ensure that the entire packing area 3 can be covered and the sewage can be evenly sprayed. Each nozzle 22 has an excellent atomization effect, which can refine the sewage into tiny water droplets, thereby increasing the contact area with the packing and improving the efficiency of biological purification. In order to ensure that the sewage in the water inlet pipe 21 can be stably and continuously supplied to the nozzle 22, the spraying area 2 is also equipped with a water pump 23. The water pump 23 is connected to the water inlet pipe 21. Through the pressure it generates, the sewage in the aerobic pool is pumped into the water inlet pipe 21, and then sprayed on the packing area 3 through the nozzle 22. The selection and installation position of the water pump 23 are carefully designed to ensure that it can meet the operation requirements of the entire system and has a high energy efficiency ratio. In addition, in order to ensure the normal operation of the spray area 2 and extend its service life, the nozzle 22 and the water pump 23 need to be regularly maintained and serviced. This includes cleaning the nozzle 22 to prevent it from clogging; checking the operating status of the water pump 23 to ensure that it can work normally; and replacing severely worn parts. In short, as an important part of the improved biological deodorization device, the design and operation of the spray area 2 are crucial. Through reasonable layout and maintenance, the stable operation of the spray area 2 can be ensured, providing a strong guarantee for the efficient deodorization of the entire system.

[0023] Combination Figure 2 and Figure 3As shown, the packing area 3 includes mounting grooves 31 arranged in multiple layers inside the reactor body 1, and all mounting grooves 31 are provided with push-pull packing boxes 32, and the packing boxes 32 are hingedly connected with covers 33, and one side of the packing boxes 32 is provided with handles 34. Specifically, the packing area 3 is located inside the reactor body 1, and its design features are reflected in the mounting grooves 31 arranged in multiple layers. These mounting grooves 31 are distributed at certain intervals and levels to ensure that the packing can make full use of the space inside the reactor while maintaining the uniformity and stability of the airflow. In each mounting groove 31, a push-pull packing box 32 is provided. This design makes the replacement and maintenance of the packing extremely convenient. When the packing needs to be replaced due to long-term use, the staff only needs to pull the old packing box 32 out of the mounting groove 31 and push the new packing box 32 in. This design not only improves work efficiency, but also reduces maintenance costs. A cover 33 is hingedly connected to the top of each packing box 32. The existence of the cover 33 not only ensures the sealing of the stuffing box 32 and prevents odor leakage, but also prevents external impurities from entering the stuffing box 32 and affecting the effect of the biological reaction. At the same time, the opening and closing design of the cover 33 also facilitates the staff to inspect and clean the inside of the stuffing box 32. A handle 34 is provided on one side of the stuffing box 32. The design of this handle 34 fully considers the principle of ergonomics, so that the staff can easily apply force when pushing and pulling the stuffing box 32, greatly reducing the labor intensity. In addition, the material selection of the handle 34 has also been carefully considered. It must have sufficient strength to withstand the pressure during the pushing and pulling process, and keep the surface smooth and comfortable to provide the best operating experience. The design of the entire stuffing area 3 fully reflects humanization and practicality. Through the multi-layer installation groove 31, the push-pull stuffing box 32, the stuffing box 32 design with the cover 33 and the convenient handle 34, the stuffing area 3 not only provides an ideal place for the biological reaction of odor and sewage, but also greatly simplifies the operation process of maintenance and replacement of stuffing, providing a strong guarantee for the efficient operation of the entire biological deodorization device.

[0024] Combination Figure 1 and Figure 2As shown, the air intake area 4 includes an air intake pipe 41 arranged inside the air-water mixing area 5, a plurality of aeration pipes 42 are arranged on the air intake pipe 41, a fan 43 is connected to the air intake end of the air intake pipe 41, and a check valve 44 is arranged on the air intake pipe 41. Specifically, the air intake area 4 mainly includes an air intake pipe 41 arranged inside the air-water mixing area 5. This air intake pipe 41 runs through the entire air-water mixing area 5 to ensure that the odor can be evenly distributed in the area, so as to be fully mixed with the purified sewage. On the air intake pipe 41, a plurality of aeration pipes 42 are arranged. These aeration pipes 42 are specially designed to release the odor into the air-water mixing area 5 in the form of tiny bubbles. This design increases the contact area between the odor and the sewage, which is conducive to the adsorption and decomposition of harmful substances in the odor by microorganisms in the sewage. A fan 43 is connected to the air intake end of the air intake pipe 41. The fan 43 is responsible for generating negative pressure, sucking the odor from the external environment into the air intake pipe 41, and pushing it to flow to the air-water mixing zone 5. The selection and use of the fan 43 should be determined according to the specific deodorization requirements and the size of the reactor body 1 to ensure that the odor can stably and continuously enter the air intake pipe 41. In addition, a check valve 44 is also provided on the air intake pipe 41. The function of the check valve 44 is to prevent the odor from flowing back to the external environment when the fan 43 stops working, thereby maintaining the air pressure in the reactor body 1 stable. The selection and installation position of the check valve 44 need to be carefully considered to ensure that it can work reliably and prevent odor leakage. The design of the entire air intake zone 4 fully considers the odor transportation efficiency, the mixing effect with sewage, and the need to prevent odor leakage. Through reasonable pipeline layout, the design of the aeration pipe 42, and the selection of the fan 43 and the check valve 44, the air intake zone 4 provides a strong guarantee for the efficient operation of the entire biological deodorization device.

[0025] Combination Figure 1 and Figure 2As shown, the gas-water mixing zone 5 includes a water outlet pipe 51 and a liquid level transmitter 52 arranged at the bottom of the reactor body 1, and the water outlet end of the water outlet pipe 51 is connected to a drainage pump 53, and an electric valve 54 is arranged on the water outlet pipe 51. Specifically, the gas-water mixing zone 5 is located at a specific position of the reactor body 1, and its design fully considers the mixing effect of sewage and odor and the discharge management of sewage. At the bottom of the gas-water mixing zone 5, an outlet pipe 51 is arranged, which is responsible for discharging the treated sewage out of the reactor body 1. The water outlet end of the water outlet pipe 51 is connected to a drainage pump 53. The drainage pump 53 serves as a power source to ensure that the sewage can be discharged stably and continuously through the water outlet pipe 51. The drainage pump 53 needs to be determined according to the processing capacity of the reactor and the discharge demand of sewage to ensure that the sewage can be discharged in a timely and effective manner. In order to control the discharge speed and discharge time of sewage, an electric valve 54 is arranged on the water outlet pipe 51. The electric valve 54 can be remotely operated through the control system, and the valve opening can be adjusted according to actual needs to control the discharge amount of sewage. This design makes the discharge of sewage more flexible and controllable, which helps to optimize the entire deodorization process. In addition, the gas-water mixing zone 5 is also equipped with a liquid level transmitter 52. The liquid level transmitter 52 can monitor the sewage level in the gas-water mixing zone 5 in real time and transmit the liquid level information to the control system. The control system can automatically adjust the working state of the drainage pump 53 and the electric valve 54 according to the liquid level information to ensure that the sewage level always remains within the appropriate range. This automated control not only improves the stability and reliability of the deodorization process, but also reduces the labor intensity of the operators. In summary, the design of the gas-water mixing zone 5 fully considers the mixing effect of sewage and odor and the discharge management of sewage. Through the coordinated use of the drainage pump 53, the electric valve 54 and the liquid level transmitter 52, the gas-water mixing zone 5 provides a strong guarantee for the efficient operation of the entire biological deodorization device.

[0026] Combination Figure 1 and Figure 2As shown, the stuffing box 32 is a container made of stainless steel mesh, and the stuffing inside the stuffing box 32 is MBBR stuffing. Specifically, the stuffing box 32 is a container for accommodating biological stuffing, and its material is stainless steel mesh. The stainless steel mesh has excellent corrosion resistance and mechanical strength, and can maintain the stability and integrity of the structure during long-term operation. In addition, the stainless steel mesh also has good air permeability and water permeability, which can ensure that odor and sewage can flow freely inside the stuffing box 32 and fully contact with the biological stuffing. Inside the stuffing box 32, MBBR (Moving Bed Biofilm Reactor) stuffing is filled. MBBR stuffing is an efficient biological carrier with a rough and porous surface that can attach a large number of microorganisms. These microorganisms will grow and multiply in a suitable environment to form a layer of biofilm. When the odor passes through the stuffing box 32, it will contact the microorganisms on the biofilm, and a biological reaction will occur, thereby removing harmful substances in the odor. The advantage of MBBR stuffing is its high specific surface area and rich microbial population. The high specific surface area means that the stuffing can provide more attachment sites, increasing the number and types of microorganisms. The rich microbial population can handle more types of pollutants and improve the deodorization efficiency. In addition, MBBR fillers also have good impact load resistance and long service life, and can adapt to various complex environmental conditions. In the design of the filler box 32, factors such as easy replacement and maintenance are also taken into consideration. Through the push-pull design, the staff can easily pull the old filler box 32 out of the installation slot 31, and then push the new filler box 32 in. This design not only improves work efficiency, but also reduces maintenance costs. At the same time, the cover and handle design of the filler box 32 also facilitate the staff to inspect and clean the internal filler. In summary, the filler box 32 and the MBBR filler filled inside it play a key role in the improved biological deodorization device. They effectively remove harmful substances in the odor and improve the deodorization efficiency by providing abundant microbial attachment sites and a good biological reaction environment. At the same time, the design that is easy to replace and maintain also ensures the long-term and stable operation of the entire deodorization device.

[0027] Combination Figure 1 and Figure 2As shown, the top of the reactor body 1 is provided with an exhaust port 6. Specifically, the exhaust port 6 is located at the top of the reactor body 1, and such a design is conducive to the natural convection and diffusion of gas inside the reactor. After the odor is fully mixed with the sewage and biologically reacted through the packing area 3, most of the harmful substances have been removed or converted. However, in order to ensure that the gas environment inside the reactor is always in the best state and to avoid the accumulation of residual odor inside the reactor, the setting of the exhaust port 6 is particularly important. The exhaust port 6 is usually connected to the external ventilation system to discharge the treated gas into the atmosphere through a pipeline. This design ensures the gas flowability inside the reactor and avoids the risk of pressure increase or gas leakage caused by gas accumulation. At the same time, the diameter and position of the exhaust port 6 are also carefully calculated to ensure that the discharged gas will not cause pollution or adverse effects on the surrounding environment. In addition, the exhaust port 6 also has some special functions. For example, it can be equipped with a gas monitoring device to monitor the composition and concentration of the exhaust gas in real time to ensure that the discharged gas meets environmental protection standards. If necessary, the exhaust port 6 can also be provided with a regulating valve to automatically adjust the discharge speed according to the changes in the gas pressure or gas composition inside the reactor to maintain the stability of the internal environment of the reactor. In summary, the exhaust port 6 at the top of the reactor body 1 plays a vital role in the improved biological deodorization device. It not only ensures the gas flowability inside the reactor and prevents the risk of gas accumulation and leakage, but also has the function of real-time monitoring and regulation of the exhaust gas, ensuring the environmental protection and safety of the entire deodorization process.

[0028] Combination Figure 1 and Figure 2As shown, the reactor body 1 is made of stainless steel. Specifically, the reactor body 1 in the improved biological deodorization device, as the core structure of the entire device, bears the important task of maintaining and treating odor. The material selection is crucial to ensure the stability, durability and safety of the device. The reactor body 1 is made of stainless steel. Stainless steel is widely used for its excellent corrosion resistance and mechanical strength. In biological deodorization devices, it is often necessary to treat odors containing various chemical components, which may corrode the equipment materials. Stainless steel can effectively resist the erosion of these chemicals, thereby ensuring the long-term stable operation of the reactor body 1. In addition, stainless steel also has good thermal conductivity and impact resistance, and can withstand temperature changes and mechanical stress that may occur during the treatment process. This is crucial to maintaining a stable biological reaction environment inside the reactor. In addition to the above-mentioned physical properties, the surface finish of stainless steel is also high, and it is not easy to accumulate dirt and microorganisms, which helps to keep the inside of the reactor clean and hygienic and reduce maintenance workload. In summary, the reactor body 1 made of stainless steel not only has excellent corrosion resistance and mechanical strength, but also can maintain good cleanliness and hygiene, and is an indispensable and important part of the improved biological deodorization device. Its excellent physical properties and processing characteristics provide a strong guarantee for the efficient and stable operation of the device.
