Description

Technical Field

[0001] The utility model relates to the technical field of air purification, in particular to a biological deodorizing device. Background Art

[0002] Common treatment methods for malodor bodies include combustion, oxidation, absorption, adsorption, neutralization and biological methods. Biological deodorization is a biological waste gas treatment technology that uses biological methods to deodorize waste odor molecules through microbial membranes specially cultivated on biological fillers in biological filter tanks. When toxic, harmful and malodorous waste gas containing a mixture of gas, liquid and solid is introduced into this system through the collection pipeline, the biofilm formed by the cultivation of efficient microbial strains grown on the biological fillers is used to purify and degrade the pollutants in the waste gas. On the one hand, this biofilm uses the pollutants in the waste gas as nutrients to grow and reproduce.

[0003] Gas deodorization is mostly carried out by adsorption. An activated carbon filter is installed in the biological deodorization equipment to adsorb the odorous gas. However, after the gas is deodorized, it is usually necessary to spray some disinfectant to sterilize the deodorized gas. The current disinfection spray mechanism and activated carbon filter are usually installed in the same chamber. If the disinfectant is sprayed out by the atomizing nozzle, the chamber is relatively humid, which affects the adsorption performance of the activated carbon filter. Utility Model Content

The air can flow into the deodorizing chamber 4, and an exhaust fan 18 can also be installed on the air inlet 2. Through the setting of the exhaust fan 18, the external gas can be sucked into the deodorizing chamber 4. The outer surface of the lower part of the separation cylinder 12 is provided with multiple rows of through holes 10 equidistantly arranged in the circumferential direction. Through the setting of multiple through holes 10, the odorous gas can flow into the disinfection chamber 3 through the through holes 10 after being processed in the deodorizing chamber 4; the top of the tower body 1 is provided with a first exhaust hole 11 connected to the disinfection chamber 3. Through the setting of the first exhaust hole 11, the disinfected gas can be discharged from the first exhaust hole 11.

[0023] An activated carbon filter 5 is installed inside the deodorizing chamber 4. The activated carbon filter 5 can adsorb and treat odorous gases.

[0024] A liquid pump 7 is installed on the outside of the tower body 1. The liquid pump 7 can be a water pump, and a water pump pipe connected to the disinfection box (not shown in the figure) is installed at the water pumping end of the liquid pump 7. The water outlet end of the liquid pump 7 is connected to the spray pipe 6 through a flange, and the spray pipe 6 extends to the interior of the deodorization chamber 4. A plurality of atomizing nozzles 8 are equidistantly installed on the deodorization chamber 4, and the injection end of each atomizing nozzle 8 extends to the interior of the disinfection chamber 3, so that the air can be disinfected in the disinfection chamber 3, reducing the phenomenon that the water mist sprayed by the atomizing nozzle 8 soaks the activated carbon filter 5, thereby ensuring the adsorption performance of the activated carbon filter 5.

[0025] The bottom end of the tower body 1 is provided with a plurality of second exhaust holes 13 , and the plurality of second exhaust holes 13 are connected to the interior of the deodorizing chamber 4 . If there is no need to sterilize the air, the odor-treated gas can be directly discharged from the second exhaust holes 13 .

[0026] A circular cylinder 141 is rotatably mounted on the outer surface of the lower part of the separating cylinder 12, a "ring-shaped" sealing plate 142 is fixed to the bottom of the circular cylinder 141, and a number of adjustment holes 15 are provided on the circular cylinder 141 and the "ring-shaped" sealing plate 142, an adjustment seat 16 is fixed to one side of the "ring-shaped" sealing plate 142, and an adjustment groove 20 is provided on the outer surface of the tower body 1, and an adjustment handle 17 is fixed to the outer surface of the adjustment seat 16, and the adjustment handle 17 passes through the adjustment seat 16 and extends to the outside of the tower body 1.

[0027] There are two working modes for odorous gases; this application can adopt any of the following modes;

[0028] The first working mode: if you only want to deodorize the gas with odor, and do not need to disinfect the deodorized gas:

[0029] First, the adjusting handle 17 is rotated so that the adjusting handle 17 drives the sealing cover 14 to rotate through the adjusting seat 16, so that the adjusting hole 15 on the "annular" sealing plate 142 is aligned with the second exhaust hole 13, and the adjusting hole 15 on the circular cylinder 141 is misaligned with the through hole 10, and the through hole 10 is blocked by the circular cylinder 141.

[0030] Then turn on the exhaust fan 18, which can draw the odorous gas from the outside into the deodorization chamber 4. The odorous gas flows downward and passes through the activated carbon filter 5, and the odor in the gas is adsorbed by the activated carbon filter 5. The treated gas is discharged through the adjustment hole 15 and the second exhaust hole 13 on the "annular" sealing plate 142 in turn, thereby completing the work of deodorizing the gas.

[0031] The second working method: If the smelly gas is to be deodorized and disinfected:

[0032] First, the adjusting handle 17 is rotated so that the adjusting handle 17 drives the sealing cover 14 to rotate through the adjusting seat 16, so that the adjusting hole 15 on the "annular" sealing plate 142 and the second exhaust hole 13 are staggered, and the second exhaust hole 13 is sealed by the "annular" sealing plate 142, and the adjusting hole 15 on the circular cylinder 141 is aligned with the through hole 10.

[0033] At the same time, the liquid pump 7 and the exhaust fan 18 are turned on. The exhaust fan 18 can be used to extract the odorous gas. After the odorous gas enters the interior of the disinfection chamber 3, the odorous gas flows downward and passes through the activated carbon filter 5. The activated carbon filter 5 can adsorb the odor in the gas; the treated gas passes through the adjustment hole 15 and the through hole 10 on the circular cylinder 141 in turn and enters the interior of the separation cylinder 12. The liquid pump 7 can extract the disinfectant in the disinfection box. The extracted disinfectant enters the interior of the spray pipe 6 through the liquid pump 7. The disinfectant in the spray pipe 6 is sprayed into the disinfection chamber 3 through multiple atomizing nozzles 8, so that the gas in the disinfection chamber 3 can be sterilized and disinfected. The sterilized and disinfected gas can be discharged from the first exhaust hole 11, thereby completing the work of sterilizing the gas.
