Technical Field

[0001] The utility model relates to the technical field of biological deodorization, in particular to an improved biological deodorization device. Background Technique

[0002] Biological deodorization technology is a new deodorization technology developed in the 1950s of the 20th century. It uses the physiological metabolism of microorganisms to degrade malodorous substances and oxidize them into odorless and harmless end products to achieve the purpose of deodorization. Compared with the currently adopted physical and chemical methods, such as combustion, adsorption, absorption, and reduction, biological deodorization technology has the advantages of less investment, low energy consumption, low operating cost, high deodorization efficiency, and can avoid or reduce secondary pollution.

[0003] At present, during the use of existing biological deodorization devices, most of them adopt a single packing layer, and during the use process, it is necessary to frequently supplement nutrients, making the overall operation rather troublesome. Content of the Utility Model

[0016] 1. The improved biological deodorization device is easy to operate. The replenishment and drainage of water in the clean water area of this device are automatically controlled. The spray water circulates in the device. The make-up water of the clean water tank is the effluent from the secondary sedimentation tank, and there is no need to frequently add nutrients, and the operation cost is low. First, the make-up water of the clean water tank is the effluent from the secondary sedimentation tank, and the effluent from the secondary sedimentation tank is the effluent from the aerobic tank. The make-up water contains certain nutrients and strains, which can be used as a nutrient source supplement for the biological deodorization device.

Meanwhile, the ordinary packing area is located in the lower layer, and the biological packing area is located at the bottom layer. This approach prolongs the biological reaction time and also improves the treatment efficiency of the biological treatment device. It is highly efficient, safe, and practical. The biological filter material is selected as volcanic rock with high hardness, wear resistance, large specific surface area, and high porosity. This packing has a long service life and has a certain adsorption function. The ordinary packing is selected as PP balls + polyurethane sponge packing. This packing has a high water absorption rate and a high specific surface area. As a humidifying packing, it can effectively increase the gas-liquid contact area. Moreover, the spray density in the ordinary packing area is large, ensuring the full dissolution of water-soluble waste gas. Brief Description of the Drawings

[0022] 3. Refer to Figure 1 , an improved biological deodorization device, including a reactor housing 1, a demister 6, a water tank 10, a spray pump 12, and a fan 13, characterized in that

[0023] The spray area includes a lower spray area 4 and an upper spray area 5, and both the lower spray area 4 and the upper spray area 5 are supplied with water through the spray pump 12;

[0024] The packing area is divided into a biological packing area 2 and a common packing area 3 according to the properties of the packing. The biological packing area 2 uses volcanic rock packing. The volcanic rock packing has advantages such as wear resistance, high hardness, high specific surface area, and high porosity. It is a good biological carrier and is the main part of the biological reaction. The common packing area 3 uses common PP balls and polyurethane sponge packing. Its main function is to absorb organic substances, ammonia, hydrogen sulfide, etc. that are easily soluble in water in the waste gas. And because the spraying density in the common packing area is large, the spraying water droplets falling into the lower-layer packing can be used as nutrients for the lower-layer packing;

[0025] The spraying areas are all arranged above the packing area. The upper spraying area 5 is arranged above the biological packing area 2, and the lower spraying area 4 is arranged above the common packing area 3. A supporting layer and a stainless steel wire mesh are provided at the bottom of both the biological packing area 2 and the common packing area 3. The stainless steel wire mesh on the outside of the biological packing area 2 is set according to the particle size of the volcanic rock packing or multiple layers of stainless steel wire meshes are set. The aperture of the stainless steel wire mesh is smaller than the particle size of the volcanic rock packing to prevent the volcanic rock packing from falling into the water and causing pump failures or pipeline blockages.

[0026] Refer to Figure 1 As described above, the water tank 10 is connected with a water tank outlet pipe 18. The water tank 10 supplies water to the spraying pump 12 through the water tank outlet pipe 18. A liquid level transmitter 11 is installed on the water tank 10. The water tank 10 is connected with a water tank make-up pipe 15 and a water tank drain pipe 16. The liquid level transmitter 11 is linked with the automatic valves installed on the water tank make-up pipe 15 and the water tank drain pipe 16. Both the lower spraying area 4 and the upper spraying area 5 are connected with spraying pipe interfaces 9. The spraying pump 12 is connected with the nozzles in the lower spraying area 4 and the upper spraying area 5 through the spraying pipe interfaces 9. An air inlet 7 is provided below the biological packing area 2. An air outlet 8 is provided at the top of the demister 6. The air outlet 8 is connected with an exhaust pipe 14. The exhaust pipe 14 is connected with a fan 13. After the waste gas enters the biological deodorization device, it passes through two layers of packing and is in full contact with the spraying water, and finally is discharged from the top exhaust port. During this process, the gas components that are easily soluble in water are dissolved in water, and the pollutants such as organic substances are dissolved in water and used as nutrients for the bottom biological packing. A water tank and device connection pipe 17 is connected to the reactor housing 1. The reactor housing 1 is connected with the water tank 10 through the water tank and device connection pipe 17. The water source of the spraying pump 12 is the effluent from the secondary sedimentation tank and tap water. Generally, the effluent from the secondary sedimentation tank is used as the water source of the spraying pump 12, and when the quality of the effluent from the secondary sedimentation tank is poor, tap water is used as the water source of the spraying pump 12. The spraying pump 12 is linked with the liquid level transmitter 11. When the spraying pump 12 starts, it is necessary to ensure that the water level in the water tank 10 meets the starting requirements of the pump. A baffle plate is arranged inside the demister 6. The material of the baffle plate is S30408. Its main function is to increase the contact path of the gas, so that the moisture in the gas can be effectively condensed, reduce the moisture content of the waste gas emission, and prevent water accumulation in the outlet pipeline or affect the adsorption efficiency and service life of the subsequent activated carbon.

[0027] In the present utility model, the waste gas first enters the device through the air inlet 7 from below the lower biological packing area 2. It first passes through the biological packing area 2 which is filled with volcanic rock packing. The main process here is biological reaction. A spray is provided above the biological packing area 2. After passing through the biological packing area 2, it enters the ordinary packing area 3 which is filled with PP balls + polyurethane sponge packing. The spray density here is large for humidification, and then the components of the waste gas that are easily soluble in water are dissolved, and then drip onto the biological packing area 2 as nutrients for the biological packing area 2. During this process, the gas passes through the biological deodorization device from bottom to top, the gas and liquid are in full contact in the spray packing area, and through the reaction of microorganisms. After reaching the standard, the gas is discharged from the top after demisting.

[0028] The above is only the preferred specific implementation mode of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes should be covered within the protection scope of the present utility model.
