Description

Technical Field

[0001] The invention relates to the field of waste gas treatment, and more specifically, to a novel multi-stage upflow biogas deodorization device. Background Art

[0002] Industrial organic waste gas refers to volatile substances produced by enterprises in the production process that can cause disgust or discomfort to the human body. It is a kind of olfactory pollution that is perceived by the human olfactory organ through the air medium. Industrial organic waste gas comes from a wide range of sources, including animal husbandry farms, slaughterhouses, petrochemicals, paint spraying, rubber, tanneries, fertilizers, garbage disposal sites, sewage treatment plants, etc., and the types of organic waste gas produced can reach tens of thousands. Among them, hydrogen sulfide, trimethylamine, formaldehyde, and volatile aromatic compounds such as benzene, toluene, and styrene are seriously harmful to human health. Industrial organic waste gas can enter the human body through the respiratory tract, digestive tract, etc., and endanger multiple tissues and organs. Among them, halogenated compounds and aromatic compounds have teratogenic, mutagenic and carcinogenic effects, and have been listed as priority controlled pollutants by governments of many countries. Biological method is a high-tech technology that combines biotechnology and environmental engineering technology. It has been recognized by experts from various countries as a mainstream, efficient, safe and reliable end-of-pipe treatment technology for organic waste gas pollution.

[0003] Biogas deodorization device is an environmental protection equipment that uses the physiological process of microorganisms to convert harmful substances in organic waste gas into harmless substances. The biogas deodorization device uses biological fillers as carriers, so that microorganisms form biofilms on the surface of biological fillers under suitable conditions. The microorganisms in the biofilm use inorganic and organic matter in the waste gas as carbon sources and energy sources, maintain their life activities by degrading odorous substances, and decompose odorous substances into odorless substances such as carbon dioxide, water, and minerals, so as to achieve the purpose of purifying odorous gas.

[0004] As the time that waste gas enters the biogas deodorization device increases, it is necessary to add biological supplementary liquid to the biological filler according to the biological treatment effect to ensure the biological treatment effect of the waste gas. In the biogas deodorization device, all biological fillers are stacked in a box, and the supplementary liquid is sprayed by multiple nozzles above the biological filler, so that the biological supplementary liquid flows from top to bottom for replenishment. However, as the biological supplementary liquid increases, the biological filler will gradually become compacted, and the porosity of the compacted filler will decrease and the air permeability will become worse, which will affect the diffusion of gas in the filler and the oxidation and decomposition efficiency of pollutants by microorganisms. At the same time, the liquid holding capacity will also decrease, resulting in the inability of the biological liquid to fully penetrate into the filler, thereby affecting the deodorization effect. For this reason, we propose a new multi-stage upflow biogas deodorization device. Summary of the invention

[0030] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0031] like Figure 1 - Fig. 9 As shown, a novel multi-stage upflow biogas deodorization device comprises: a deodorization device housing 11, an air inlet chamber 15 is arranged in the deodorization device housing 11, an exhaust gas inlet pipe 12 is arranged at the air inlet end of the air inlet chamber 15, a primary biological deodorization mechanism 2 is arranged at one side of the air inlet chamber 15, a settling chamber 17 is arranged at the side of the primary biological deodorization mechanism 2 away from the air inlet chamber 15, a secondary biological deodorization mechanism 3 is arranged at the side of the settling chamber 17 away from the primary biological deodorization mechanism 2, and an outlet pipe 13 is arranged at the outlet end of the secondary biological deodorization mechanism 3;

[0032] After the organic waste gas enters the air inlet chamber 15 through the waste gas inlet pipe 12, it flows downward into the slow air chamber 16 through the expansion air distribution plate 19. The slow air chamber 16 is arranged below the expansion air distribution plate 19. A slow air chamber 2 18 is arranged on one side of the slow air chamber 16. Under the guidance of the expansion air distribution plate 19 of the slow air chamber 16, the organic waste gas flows upward from the bottom of the high-concentration primary biological deodorization mechanism 2, playing the role of upflow. The gas discharged from the primary biological deodorization mechanism 2 flows downward through the settling chamber 17 and enters the slow air chamber 2 18. After that, the gas in the slow air chamber 2 18 is evenly distributed through the expansion air distribution plate 19, and passes through the secondary biological deodorization mechanism 3 from bottom to top and is discharged from the outlet pipe 13;

[0033] The structure of the first-stage biological deodorization mechanism 2 is the same as that of the second-stage biological deodorization mechanism 3, except that the biological fillers therein are different, and the porosity of the fillers is inconsistent. The filtration rate of the air inlet chamber 15 and the exhaust gas inlet pipe 12 is 2-4m / s, and the total biological deodorization residence time is 15-20s. The residence time of each stage of biological deodorization is adjusted and designed according to actual conditions, and can be taken as 5-10s respectively.

[0034] The primary biological deodorizing mechanism 2 includes a layered liquid replenishing component, a loosening component, and a plurality of biological filling inner boxes 25 arranged in layers for containing biological filling materials, and the layered liquid replenishing component is connected to the loosening component;

[0035] The layered liquid replenishing component is used to spray and add microorganisms to the biological filler in the multi-layer biological filler inner box 25, and the loosening component is used to promote the fluctuation of the biological filler in the biological filler inner box 25 when cooperating with the layered liquid replenishing component to spray and add microorganisms to the biological filler.

[0036] When it is necessary to add biological liquid to the biological filler in the biological filler inner box 25, the layered liquid replenishing part can be rotated out and spray each layer of biological filler separately. This design ensures the uniform distribution of the biological liquid and avoids the problem of uneven liquid replenishment that may occur in the traditional method of treating all biological fillers as a whole, thereby improving the utilization rate and deodorization effect of the biological filler and allowing each layer of biological filler to work independently without interfering with each other, which helps to carry out targeted treatment according to the specific conditions and needs of each layer of biological filler, thereby improving the deodorization efficiency and flexibility;

[0037] The loosening aid slides from under the biological filler while replenishing the liquid, causing the biological filler to pass through like a wave. This design: first, can automatically loosen the biological filler to prevent it from agglomerating or hardening due to long-term use; second, by loosening the biological filler, its surface area and porosity are increased, which is beneficial to the penetration of biological fluid and the growth and reproduction of microorganisms; third, it improves the air permeability and liquid holding capacity of the biological filler, further enhancing the deodorization effect.

[0038] The primary biological deodorization mechanism 2 also includes a biological filling outer box 21, and the inner wall of the biological filling outer box 21 is respectively provided with a plurality of side grooves 23 corresponding to each other on the left and right sides. The insides of the plurality of side grooves 23 are rotatably provided with assembly plate seats 24, and the assembly plate seats 24 are used to place the biological filling inner box 25.

[0039] A guide channel 22 is provided inside the wall panel of the biological filling outer box 21, and the liquid inlet end of the guide channel 22 is connected to a connecting pipe 206. The end of the connecting pipe 206 away from the liquid inlet end of the guide channel 22 is connected to a liquid supply pipe 14 distributed along the top wall inside the deodorizing device box body 11. A plurality of spiral nozzles 101 are provided on the lower wall of the liquid supply pipe 14, and the liquid supply pipe 14 is connected to the guide channel 22 through the connecting pipe 206.

[0040] Two water pumps installed outside the deodorization device housing 11 are used to inject corresponding biological supplementary liquid into the distribution liquid supply pipes 14 on the primary biological deodorization mechanism 2 and the secondary biological deodorization mechanism 3 respectively, and then a plurality of spiral nozzles 101 spray the biological supplementary liquid of the corresponding primary biological deodorization mechanism 2 and the secondary biological deodorization mechanism 3 onto the top layer of biological filler;

[0041] A portion of the biological supplement liquid in the liquid supply pipe 14 enters the guide channel 22 through the connecting pipe 206.

[0042] The layered liquid replenishing component includes a plurality of turntables 202 rotatably arranged on the lower wall of the assembly plate base 24, an extension arm 29 is fixedly arranged on one side of the outer wall of the turntable 202, a plurality of spray nozzles 201 are fixedly arranged on the lower wall of the extension arm 29, a channel is arranged inside the extension arm 29, and a liquid inlet hose 26 is connected to the liquid inlet end of the channel, and the end of the liquid inlet hose 26 away from the turntable 202 is communicated with the guide channel 22.

[0043] An expansion liquid column 205 is fixedly arranged on the other side of the outer wall of the turntable 202, and a liquid filling chamber 204 is provided at the liquid inlet end of the expansion liquid column 205. The liquid filling chamber 204 is connected with another liquid outlet port of the liquid inlet hose 26 through a hose. The liquid inlet hose 26 is respectively provided with three liquid outlet ports. The expansion liquid column 205 is elastic, and a torsion spring sheet 203 is fixedly arranged inside the turntable 202.

[0044] The assembly plate seat 24 is opened from the side groove 23, and a plurality of biological filling inner boxes 25 are gradually placed in the biological filling outer box 21 from bottom to top. When the biological filling material needs to be supplemented with biological supplementary liquid, the high-speed flow guide channel 22 flows into the liquid inlet hose 1 26, and then flows into the extension arm 29 through the liquid inlet hose 1 26, and then sprayed on the biological filling materials in different biological filling inner boxes 25 by a plurality of spray nozzles 201. The primary biological deodorization mechanism 2 is composed of a plurality of biological filling outer boxes 21 filled with biological filling materials, which plays a modular role;

[0045] While the flow guide 22 is injecting liquid into the liquid inlet hose 26, a portion of the liquid flows into the liquid filling chamber 204 through the hose. As the liquid in the liquid filling chamber 204 increases, the expansion liquid column 205 expands and extends. The expansion liquid column 205 pushes the turntable 202 to rotate 90 degrees, so that the extension arm 29 rotates to the top of the biological filling inner box 25, so that the biological supplement liquid is evenly sprayed on each layer of biological filling material.

[0046] After the fluid replenishment is completed, the biological supplement liquid is stopped from continuing to be injected into the connecting tube 206. When the expansion liquid column 205 stops injecting fluid, the expansion liquid column 205 reduces the supporting force. At this time, the elasticity of the torsion spring sheet 203 causes the extension arm 29 to rotate back to its original position.

[0047] The loosening aid includes a liquid filling chamber 48 opened inside the wall panel of the assembly plate seat 24, a piston body 47 is slidably arranged inside the liquid filling chamber 48, a tension line 49 is fixedly arranged on one side of the piston body 47, the liquid inlet end of the liquid filling chamber 48 is connected to a liquid inlet hose 46, and the end of the liquid inlet hose 46 away from the liquid filling chamber 48 is connected to the last liquid outlet port of the liquid inlet hose 26.

[0048] A positioning groove 27 is formed on the upper wall of the assembly plate seat 24 , and a rotating seat 28 is rotatably disposed inside the positioning groove 27 .

[0049] A push and shake plate 41 is slidably provided on the inner bottom wall of the biological filling inner box 25, and the push and shake plate 41 is a triangular prism structure. Both ends of the push and shake plate 41 penetrate the side wall plate of the biological filling inner box 25, and both ends of the push and shake plate 41 are fixedly provided with a force-bearing slide plate 42, and the force-bearing slide plate 42 is slidably connected to the side wall plate of the biological filling inner box 25, and a plurality of elastic bands 43 are fixedly provided on one side of the force-bearing slide plate 42.

[0050] A winding cable 44 is fixedly provided on one side of the force-bearing slide 42 away from the elastic band 43, and a winding drum 45 rotatably connected to the lower wall of the biological filling inner box 25 is provided on one end of the winding cable 44 away from the force-bearing slide 42, and the winding drum 45 matches the positioning groove 27 and the rotating seat 28.

[0051] When the extension arm 29 rotates out to spray the replenishing liquid through the spray nozzle 201, a part of the replenishing liquid is separated from the liquid inlet hose 1 26 and enters the liquid inlet hose 2 46, and flows into the liquid filling chamber 2 48 through the liquid inlet hose 2 46. As the liquid in the liquid filling chamber 2 48 increases, the piston body 47 is pushed to slide, and the pulling line 49 wound by the rotating seat 28 is pulled by the piston body 47, so that the rotating seat 28 rotates in the positioning groove 27, and the rotating seat 28 drives the winding drum 45 to rotate, and the winding wire 44 is gradually wound at the same time, and the force-bearing slide plate 42 is pulled by the winding wire 44 to slide, and the force-bearing slide plate 42 drives the pushing plate 41 to slide close to the biological filling inner box 25, and the biological filling material is pushed by the pushing plate 41 to fluctuate like a wave, so that the biological filling material is loosened;

[0052] Afterwards, the stressed slide plate 42 is pulled back to its original position by the elasticity of the plurality of elastic bands 43 .

[0053] An expansion air distribution plate 19 is fixedly installed below the air inlet chamber 15, the first-level biological deodorization mechanism 2, the settling chamber 17 and the second-level biological deodorization mechanism 3. The expansion air distribution plate 19 has a groove and an air hole on the air inlet side in the direction of exhaust gas travel, and the groove gradually decreases along the exhaust gas width. The exhaust gas can evenly enter the first-level biological deodorization mechanism 2 and the second-level biological deodorization mechanism 3 through the air holes of the expansion air distribution plate 19.

[0054] The above describes an embodiment of the present embodiment, but the present embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present embodiment, ordinary technicians in this field can also make many forms, all of which are within the protection of the present embodiment.
