Description

Technical Field

[0001] This utility model relates to the field of environmental protection technology, and in particular to a biological odor control device based on a highly efficient compound microbial agent. Background Technology

[0002] Biological odor control technology, as an important means in the field of environmental protection, has been widely used in various locations such as industry, municipalities, and livestock and poultry farms due to its environmental friendliness and economic efficiency. Typical technologies such as biofilters and biotrickling filters utilize the metabolic processes of microorganisms to decompose pollutants in odorous gases into harmless substances, achieving effective removal of pollutants. This treatment method not only avoids secondary pollution but also has advantages such as low operating costs and ease of operation, making it of great significance for improving environmental quality and protecting the ecological environment.

[0003] However, traditional systems that rely on packing to immobilize microorganisms are prone to microbial activity decay, making replenishment or replacement difficult. Especially when facing shock loads or changes in composition, the system's adaptability is poor. Secondly, insufficient contact between odorous gases and microorganisms leads to low mass transfer efficiency, limiting treatment speed and effectiveness. Furthermore, while forced turbulence can increase gas-liquid contact opportunities, it also increases energy consumption, and the packing layer is prone to clogging, leading to increased pressure drop and higher maintenance costs. Finally, existing systems may also generate pollutants such as wastewater, sludge, and waste gas during use, posing a risk of secondary pollution. Utility Model Content

[0004] The purpose of this invention is to provide a biological odor control device based on a highly efficient composite microbial agent. This addresses the problems of existing systems that rely on packing material to immobilize microorganisms, where the microbial agent activity easily declines, making replenishment or replacement difficult. Furthermore, the system's adaptability is poor, especially when facing shock loads or changes in composition. Secondly, insufficient contact between odorous gases and microorganisms leads to low mass transfer efficiency, limiting treatment speed and effectiveness. Additionally, while forced turbulence increases gas-liquid contact opportunities, it also increases energy consumption, and the packing layer is prone to clogging, leading to increased pressure drop and higher maintenance costs. Finally, existing systems may generate wastewater, sludge, and waste gas during operation, posing a risk of secondary pollution.

[0005] To achieve the above objectives, this utility model employs a biological odor control device based on a highly efficient composite microbial agent, comprising a water washing circulation layer, a biodegradation layer, a demisting layer, and a tower body. The water washing circulation layer includes a water tank, an air inlet, a spray packing end, and a spray nozzle matrix. The water tank is located below the air inlet, which is located below the spray packing end, and the spray packing end is located below the spray nozzle matrix. The biodegradation layer includes an atomizing nozzle matrix, a non-powered turbulence end, and a bioreaction chamber. The atomizing nozzle matrix uses high-pressure nozzles and is located below the non-powered turbulence end, which is located below the bioreaction chamber.

[0006] The tower body is a vertical tower structure, the water washing circulation layer is located at the bottom of the tower body, the biodegradation layer is located in the middle layer of the tower body, and the demisting layer is located at the top of the tower body.

[0007] The water tank is provided with an air inlet, and the air inlet is connected to the air inlet, with the airflow direction being from bottom to top.

[0008] The spray filler end is provided with a first stainless steel support mesh plate, on which a polymer multifaceted hollow sphere is supported.

[0009] The spray nozzle matrix is ​​spiral in shape, and the spray angle of the spray nozzle matrix is ​​90° to 120°.

[0010] The non-powered flow-disrupting end consists of multiple stainless steel guide pipes arranged at multiple angles, and each stainless steel guide pipe has a spiral guide plate inside.

[0011] The second stainless steel support mesh plate is provided below the demisting layer, and a polymer Pall ring packing is provided above the second stainless steel support mesh plate.

[0012] This invention discloses a biological odor control device based on a highly efficient composite microbial agent. The biodecomposition layer employs a high-pressure atomizing nozzle matrix to directly spray the highly efficient composite microbial agent, achieving high-activity dispersion and flexible replenishment, significantly improving the system's adaptability to shock loads and compositional changes. The non-powered turbulence end utilizes multi-angled stainless steel guide pipes and an internal spiral guide plate design to forcibly generate turbulence using gas kinetic energy, ensuring thorough mixing of microbial agent droplets and odorous gases, greatly enhancing the mass transfer process. The non-powered turbulence structure achieves efficient mixing without additional energy consumption, while avoiding increased pressure drop and maintenance costs due to packing layer blockage. The demisting layer effectively intercepts droplets, bacteria, and particles in the exhaust gas using polymeric Pall ring packing, ensuring clean emissions and preventing microbial agent loss and secondary pollution. Overall, this device achieves highly efficient, low-energy-consumption, and stable odor control through the synergistic effect of the water washing circulation layer, biodecomposition layer, and demisting layer.

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0019] Please see Figures 1 to 3 This utility model provides a biological odor control device based on a highly efficient compound microbial agent, comprising a water washing circulation layer 1, a biodegradation layer 2, a demisting layer 3, and a tower body 4. The water washing circulation layer 1 includes a water tank 6, an air inlet 7, a spray packing end 8, and a spray nozzle matrix 9. The water tank 6 is located below the air inlet 7, the air inlet 7 is located below the spray packing end 8, and the spray packing end 8 is located below the spray nozzle matrix 9. The biodegradation layer 2 includes an atomizing nozzle matrix 10, a non-powered turbulence end 11, and a bioreaction chamber 12. The atomizing nozzle matrix 10 uses high-pressure nozzles and is located below the non-powered turbulence end 11, which is located below the bioreaction chamber 12.

[0020] In this embodiment, by integrating three functional layers—water washing circulation, biodegradation, and demisting—comprehensive purification of odorous gases is achieved. The tower body 4 has a compact structure, and the layers work together to improve processing efficiency and stability.

[0021] Furthermore, the tower body 4 is a vertical tower structure, the water washing circulation layer 1 is located at the bottom layer of the tower body 4, the biodegradation layer 2 is located in the middle layer of the tower body 4, and the demisting layer 3 is located at the top layer of the tower body 4.

[0022] In this embodiment, the vertical tower structure facilitates airflow from bottom to top, forming an orderly processing flow; the water washing circulation layer 1 is located at the bottom, which can initially purify the gas and regulate humidity; the biodegradation layer 2 is located in the middle, realizing efficient biodegradation; the demisting layer 3 is located at the top, ensuring clean exhaust gas. This layered design optimizes the treatment effect.

[0023] Furthermore, the water tank 6 is provided with an air inlet 5, and the air inlet end 7 is connected to the air inlet 5, and the airflow direction is from bottom to top.

[0024] In this embodiment, by setting an air inlet 5 on the water tank 6 and connecting it to the air inlet end 7, it is ensured that the malodorous gas can smoothly enter the treatment system; the airflow flows from bottom to top, which conforms to the principle of natural convection and helps the gas to be evenly distributed and fully treated in the tower body 4.

[0025] Furthermore, a first stainless steel support mesh plate is provided below the spray filler end 8, and a polymer multifaceted hollow sphere is supported on the first stainless steel support mesh plate.

[0026] In this embodiment, the first stainless steel support mesh provides a stable support structure for the polymer multifaceted hollow spheres, ensuring the uniform distribution and durability of the filler. As filler, the polymer multifaceted hollow spheres increase the gas-liquid contact area, improve mass transfer efficiency, and reduce pressure drop and blockage risk.

[0027] Furthermore, the spray nozzle matrix 9 is spiral in shape, and the spray angle of the spray nozzle matrix 9 is 90° to 120°.

[0028] In this embodiment, the spiral spray nozzle matrix 9 can produce a uniform spraying effect, ensuring that the spray liquid can fully cover the filler layer. The spray angle design of 90° to 120° allows the spray liquid to be sprayed at a suitable angle and range, further improving the humidity control and dust removal effect.

[0029] Furthermore, the non-powered flow-disrupting end 11 is composed of multiple stainless steel flow guides arranged at multiple angles, and each of the stainless steel flow guides has a spiral flow guide plate inside.

[0030] In this embodiment, the non-powered turbulence end 11 uses the kinetic energy of the gas itself to generate intense turbulence through the design of stainless steel guide pipes arranged at multiple angles and internal spiral guide plates, so that the micro-droplets of the bacterial agent are fully mixed and contacted with the malodorous gas. This design significantly improves the mass transfer efficiency, reduces energy consumption, and avoids the high energy consumption and packing blockage problems caused by traditional forced turbulence methods.

[0031] Furthermore, a second stainless steel support mesh plate is provided below the demisting layer 3, and a polymeric Pall ring packing is provided above the second stainless steel support mesh plate.

[0032] In this embodiment, the second stainless steel support mesh provides stable support for the polymeric Pall ring packing, ensuring the uniform distribution of the packing. The polymeric Pall ring packing has a large specific surface area and excellent demisting performance, which can effectively intercept droplets, bacteria and particles in the exhaust gas, ensuring clean exhaust gas and avoiding secondary pollution and loss of bacterial agent.

[0033] This invention also includes a dosing device, which includes a medicine tank 13 and a dosing pump. The dosing pump delivers the medicine solution in the medicine tank 13 to the water tank 6.

[0034] In this invention, the spraying method of the atomizing nozzle matrix 10 allows the highly efficient composite microbial agent to directly enter the treatment core in a highly active and highly dispersed state, making instantaneous and large-area contact with the malodorous gas, significantly improving the initial degradation rate; the microbial agent replenishment is flexible and convenient, and can quickly adapt to changes in pollutant concentration and type or shock load; the non-powered turbulence end 11 utilizes the kinetic energy of the gas itself, through an array of staggered guide plate tubes, to force the generation of intense turbulence, fully mixing the microbial agent with the odorous gas, greatly enhancing the mass transfer process, and significantly reducing system operating energy. It is energy-efficient and conforms to the trend of energy conservation and environmental protection. The atomized bacterial agent and nutrient solution continuously provide active microorganisms and nutrients. The non-powered turbulence end 11 has a simple and reliable structure with no moving parts, is not prone to failure, and is highly adaptable to complex and fluctuating malodorous gases. The demister layer 3 adopts a high-efficiency demister, which effectively removes droplets, bacteria and particles entrained in the exhaust gas, ensuring clean exhaust gas and avoiding secondary pollution and ineffective loss of bacterial agent. The benchtop design also has no complex packing layer, which fundamentally avoids clogging problems. It has a small pressure drop, a relatively simple structure, fewer maintenance points, and low energy consumption operation.

[0035] In this invention, malodorous gas enters through the air inlet 5 on the water tank 6, flows upward through the air inlet end 7 to the spray packing end 8, below which is a first stainless steel support mesh plate supporting high-polymer multifaceted hollow sphere packing. This, combined with the circulating liquid sprayed by the spray nozzle matrix 9 (using a spiral design with spray angles of 90°–120°), achieves gas humidification and preliminary dust removal. Subsequently, the gas enters the biodegradation layer 2, where the atomizing nozzle matrix 10 (using high-pressure nozzles) atomizes and sprays in a highly efficient composite bacterial agent. This agent comes into full contact with the gas, which is forced into turbulent mixing by the non-powered turbulence end 11 (composed of multiple stainless steel guide tubes with internal spiral guide plates arranged at multiple angles), enhancing mass transfer efficiency and promoting biodegradation. Finally, the gas enters the demisting layer 3, where droplets and particles are intercepted by the high-polymer Pall ring packing supported on the second stainless steel support mesh plate, ensuring clean exhaust.

[0036] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
