Description

Biological deodorization reaction device

technical field

The utility model relates to a biological deodorization reaction device, which is suitable for removing the odor produced in the process of processing high-concentration organic waste, and is especially suitable for the centralized treatment of urban public toilet wastewater and the removal of odor generated in the process of urban garbage treatment. .

Background technique

The current deodorization technologies mainly include chemical deodorization, physical deodorization and biological deodorization. The mechanism of biological deodorization is to cultivate and utilize the symbiotic characteristics of various microorganisms and the role of metabolism to convert odorous substances into microbial cell substances, or be degraded by microorganisms into water, carbon dioxide and trace residual gases, so that the emitted gases can reach the national GB14554- 93 secondary standard requirements. Due to the advantages of low cost, clean technology and no secondary pollution, biological deodorization is the main development direction of deodorization at present. However, biological deodorization has higher requirements on equipment and bioreactors, requiring the filler in the reactor to have a large enough surface area for microorganisms to attach, and a certain amount of water and nutrients for microorganisms to thrive. General bioreactors are filled with ceramsite, ceramics and sand, and a water spray device is installed on the upper part of the bioreactor. However, the surface area of ceramsite, ceramics and sand is relatively small; the water droplets of water spray are relatively large, and the water sprayed is less, which makes the water content in ceramsite, ceramics and sand uneven, which cannot meet the needs of microorganisms. Many microorganisms need to be discharged, and some microorganisms are taken away in the discharge, which greatly reduces the deodorization effect of the bioreactor. In order to improve the treatment effect and make the treated gas meet the standard discharge, pretreatment is generally carried out before the biological deodorization reaction device to remove acidic and alkaline odor-causing substances, and then the component type biological deodorization filter tower (biological deodorization reaction device) Remove organic odor and remaining inorganic acid-base odor-causing substances. For example, the publication number is the solid washing-biological filter tower collaborative deodorization method of CN 101036852A. However, the existing method has cumbersome procedures, complex equipment, large site occupation and high cost, which is not conducive to mass production and application.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

Referring to the accompanying drawings, the biological deodorization reaction device of the utility model includes a biological deodorization reactor 1, which can be cylindrical or square, and the shell is welded by polypropylene. The top of the biological deodorization reactor 1 is provided with an exhaust hole 2, and the exhaust hole 2 is connected with an external exhaust tube 20 to discharge the treated gas. There is an emptying port 21 at the lower part of the biological deodorization reactor 1, which is used to discharge the liquid deposited at the bottom of the reactor. The lower part also has a thermometer 22 for detecting the temperature in the reactor. The interior of the biological deodorization reactor 1 is a layered structure, generally 2-6 layers. The layers are separated by separators 3 . Each layer is provided with a manhole 18 and an observation hole 19. The bottom layer of the biological deodorization reactor 1 is an air distribution layer 4, and the layers above the air distribution layer 4 are malodorous gas treatment layers 6. An air distribution pipe 5 is installed in the air distribution layer 4, and the outer end of the air distribution pipe 5 is an odor inlet 7, and the outside of the odor inlet 7 is connected to the odor pipe. Air outlets are all covered with on the air distribution pipe 5 . A gas-liquid flow hole 8 is arranged on the separator 3 , and a filler 9 is placed above the separator 3 . The filler 9 is square and is a high molecular organic material with a specific surface area of 3000 and a water absorption rate of 3000%, such as polypropylene, polyethylene or polyurethane. The gas-liquid flow hole 8 accounts for 4/5 of the area of the dividing plate 3, and its diameter is 1/2 of the size of the filler 9, so the filler 9 will not leak from the gas-liquid flow hole 8 of the dividing plate 3. An atomizing pipeline 10 is installed below the partition plate 3, and the atomizing pipeline 10 is provided with a spraying device 11 facing downwards. The spraying device 11 is an atomizing nozzle or an atomizing nozzle hole. The atomized droplets are smaller than 80μm. The atomizing pipelines 10 of each layer are connected to the atomizing main pipe 12 . The atomization main pipe 12 is connected with the outlet of the high-pressure atomization pump 13 outside the biological deodorization reactor 1 . The inlet of the high-pressure atomizing pump 13 is connected to the outlet of the water tank 14, and the inlet of the water tank 14 is connected to the running water pipe 15 and the microbial bacterial liquid and the nutrient solution tank 16 through a dispensing pump 17.

The working process of the utility model is: before the deodorization equipment is started, the filler 9 is added to the partition plate 3 inside the biological deodorization reactor 1 through the manhole 18 on the shell. The odor in the odor pipeline reaches the air distribution pipe 5 through the odor inlet 7, through the uniform air distribution, passes through the gas-liquid circulation holes 8 on each partition 3 from bottom to top, and then passes through the packing 9. At the same time, the microbial bacteria liquid and the nutrient solution tank 16 are pumped into the water tank 14 together with the tap water through the dispensing pump 17, and the water is converted into an atomized liquid by the high-pressure atomizing pump 13, and enters the water of each layer through the atomizing main pipe 12. The atomizing pipeline 10 sprays downwards from the spraying device 11 and sprays onto the filler 9 . When the bottom-up malodorous gas collides with the top-down mist (water, microbial bacterium liquid and nutrient solution), part of it falls on the surface of the filler 9, and part of it is brought into the filler 9 by the malodorous gas. After the malodorous gas interacts with the microorganisms in the filler, the odor and harmful components in the malodorous gas are removed. The treated gas is finally discharged through an exhaust tube (13) connected to the exhaust hole (12) on the top of the casing. Since the filler 9 has a large specific surface area and a high water absorption rate, there are more microorganisms attached to the filler 9 and more moisture is absorbed. Normally no moisture is discharged from the drain opening 21 in the lower part of the housing. Therefore, the water, microbial bacterium liquid, and microbial nutrient solution meet the water and nutrition required by the microbial metabolism, and meet the number of microbial bacteria required for odor removal. The more layers in the reactor, the better the effect of dealing with the odor. In order to enhance the effect of the microbial inoculum, before the deodorization equipment is started, the solid microbial inoculum can be evenly sprayed onto the filler 9 through the observation hole 20 on the housing.
