Description

Technical Field

[0001] This utility model relates to the field of environmental protection equipment, and in particular to a device for deep oxidation and deodorization of odorous gases at the end of the process. Background Technology

[0002] With accelerated industrialization and continuous growth in energy consumption, odor emissions from industrial production, transportation, and residential sources have become one of the major sources of global environmental pollution. These odorous gases include sulfur dioxide (SO₂). ), nitrogen oxides ( ), volatile organic compounds (VOCs), particulate matter ( Pollutants such as nitrogen oxides and sulfur dioxide not only exacerbate the greenhouse effect, cause acid rain, deplete the ozone layer, and lead to frequent smog, but also invade the human body through the respiratory system, causing respiratory diseases and seriously threatening ecological balance and human health.

[0003] While current mainstream odor treatment technologies have reduced pollutant concentrations to some extent, they still have significant limitations: First, their treatment efficiency is insufficient. Traditional technologies such as catalytic combustion and electrostatic precipitators have low synergistic removal efficiency for complex odor components (such as those containing low concentrations of VOCs and multiphase mixed pollutants), making it difficult to meet increasingly stringent emission standards. Second, they are energy-intensive and costly. Technologies such as activated carbon adsorption regeneration and membrane separation rely on energy-intensive equipment, and the short replacement cycle of adsorption materials increases the long-term operating costs for enterprises. Furthermore, their adaptability is poor. Some biological treatment processes are limited by environmental conditions such as temperature and humidity, and cannot stably treat intermittent industrial odors. To address these problems, this application proposes a solution. Summary of the Invention

[0004] Purpose of the utility model: The purpose of this utility model is to provide a device for deep oxidation and deodorization of odorous gases at the end of the process. This device can deeply treat odorous gases, oxidize and retain harmful substances in the odorous gases, and discharge harmless gases. At the same time, it can improve the treatment efficiency and be used for odorous gases in various occasions.

[0005] Technical Solution: The present invention discloses a device for deep oxidation and deodorization of odorous gases at the end of the process, comprising a tower body, a gas distribution layer at the bottom of the tower body, a gas distribution pipe in the gas distribution layer connected to an air inlet, a plurality of nano-microbubble generators at the top of the gas distribution layer, the air outlets of the plurality of nano-microbubble generators connected to a biological deodorizing liquid filter layer, a biological packing layer connected to the top of the biological deodorizing liquid filter layer, a demisting layer at the top of the biological packing layer, and an air outlet at the top of the demisting layer.

[0006] After the odorous gas enters the gas distribution layer through the air inlet of the tower, it is evenly dispersed within the gas distribution layer and then enters the nano-microbubble generator. After forming nano-sized bubbles, the gas enters the biological deodorizing liquid filter layer, where it comes into full contact with the biological deodorizing liquid. An oxidation reaction occurs, and some of the toxic substances in the odorous gas are oxidized and trapped. The clean gas continues to rise, and some of the nano-sized bubbles continue to mix with the biological deodorizing liquid. Under the action of air pressure, the gas enters the biological packing layer, where it continues to be fully oxidized. Toxic substances are trapped in the biological packing layer. Finally, the clean gas enters the demister layer under the action of air pressure, where the liquid that has been carried to the top by the high-pressure gas is further trapped. Finally, the clean gas is discharged from the tower through the air outlet at the top of the tower.

[0007] Preferably, the air distribution pipe includes a main air distribution pipe and a branch air distribution pipe. The main air distribution pipe is connected to the air inlet, the air outlet of the main air distribution pipe is connected to the branch air distribution pipe, and the air outlet of the branch air distribution pipe faces the nano-microbubble generator.

[0008] The arrangement of the main and branch gas distribution pipes further disperses the odor evenly within the gas distribution layer before it enters the nano-microbubble generator, preventing excessive pressure in some areas due to uneven odor distribution, which could damage the nano-microbubble generator.

[0009] Preferably, the radial cross-section of the nano-microbubble generator layer composed of multiple nano-microbubble generators is matched with the radial cross-section of the air distribution layer, and is also matched with the radial area of ​​the biological deodorizing liquid filter layer.

[0010] The design that matches the area of ​​the nano-microbubble generator layer with the areas of the gas distribution layer and the biological deodorizing liquid filter layer allows the odor to enter the biological deodorizing liquid filter layer more evenly, making full contact with the biological deodorizing liquid and improving the efficiency of the oxidation reaction.

[0011] Preferably, the radial area of ​​the biological deodorizing liquid filter layer is larger than the radial area of ​​the biological packing layer, and a sealing plate is filled between the circumference of the biological packing layer and the inner wall of the tower.

[0012] Using sealing plates to separate the biological packing layer from the inner wall of the tower helps protect the inner wall of the tower and improves the overall lifespan of the tower.

[0013] Preferably, a plurality of humidifying nozzles are uniformly arranged on the top of the biological packing layer, with the outlet of the humidifying nozzles facing the biological packing layer and the inlet of the humidifying nozzles connected to a high-pressure submersible pump.

[0014] The humidifying nozzle is designed to further clean the clean gas rising from the packing layer. After dissolving the residual odor in the gas in the water, it falls back into the biological packing layer and reacts with the residual deodorizing liquid in the biological packing layer to further improve the effect of oxidation and deodorization.

[0015] Preferably, the demisting layer adopts a honeycomb or corrugated filler structure.

[0016] Using a honeycomb or corrugated packing structure allows water mist to be captured on the surface of the packing due to inertial collision and interception diffusion, and then eventually flow back into the biological packing layer.

[0017] Preferably, the tower body is provided with a plurality of maintenance manholes evenly distributed on the tower body, and a maintenance layer is provided in the tower body at the height of the maintenance manholes.

[0018] Preferably, the tower body is equipped with a level gauge for detecting the liquid level of the biological deodorizing liquid filter layer.

[0019] The level gauge is used to monitor the level of the biological deodorizing liquid in the filter layer, so that the biological deodorizing liquid can be replenished at any time.

[0020] Beneficial effects: Compared with the prior art, this utility model has the following advantages:

[0021] This invention uses a nano-microbubble generator to break down odorous gases into nano-sized bubbles, which then come into full contact with the deodorizing liquid. An oxidation reaction occurs, trapping harmful substances in the odorous gases and releasing clean gas. The design of the biological filler and the demisting layer increases the contact time between the odorous gases and the deodorizing liquid, further improving the treatment efficiency. At the same time, by changing different deodorizing liquids, it can be applied to a variety of different odors, making it suitable for a wide range of applications. Attached Figure Description

[0026] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0027] Example 1:

[0028] See appendix Figures 1-3Figure shows the device for deep oxidation and deodorization of odorous gases according to this utility model. It includes a tower body 1, a gas distribution layer 2 at the bottom of the tower body 1, a gas distribution pipe in the gas distribution layer 2 connected to an air inlet, a plurality of nano-microbubble generators 3 at the top of the gas distribution layer 2, an air outlet of the plurality of nano-microbubble generators 3 connected to a biological deodorizing liquid filter layer 4, a biological packing layer 5 at the top of the biological deodorizing liquid filter layer 4, a demisting layer 6 at the top of the biological packing layer 5, and an air outlet 7 at the top of the demisting layer 6.

[0029] In this embodiment, the air distribution pipe includes an air distribution main pipe 8 and an air distribution branch pipe 9. The air distribution main pipe 8 is connected to the air inlet 10, the air outlet of the air distribution main pipe 8 is connected to the air distribution branch pipe 9, and the air outlet of the air distribution branch pipe 9 faces the nano-microbubble generator 3.

[0030] By setting up the main gas distribution pipe 8 and the branch gas distribution pipe 9, the odor is further evenly dispersed in the gas distribution layer 2 and then evenly enters the nano-microbubble generator 3, preventing the uneven distribution of odor from causing excessive pressure in some places and damaging the nano-microbubble generator 3.

[0031] In this embodiment, the radial cross-sectional size of the nano-microbubble generator layer composed of multiple nano-microbubble generators 3 is matched with the radial cross-sectional size of the air distribution layer 2, and is also matched with the radial area of ​​the biological deodorizing liquid filter layer 4.

[0032] The design that matches the area of ​​the nano-microbubble generator layer with the area of ​​the gas distribution layer 2 and the biological deodorizing liquid filter layer 4 allows the odor to enter the biological deodorizing liquid filter layer 4 more evenly, making full contact with the biological deodorizing liquid and improving the efficiency of the oxidation reaction.

[0033] In this embodiment, the radial area of ​​the biological deodorizing liquid filter layer 4 is larger than the radial area of ​​the biological packing layer 5. A sealing plate 11 is filled between the circumference of the biological packing layer 5 and the inner wall of the tower body 1. Using the sealing plate 11 to separate the biological packing layer 5 from the inner wall of the tower body 1 helps to protect the inner wall of the tower body 1 and improve the overall lifespan of the tower body 1.

[0034] In this embodiment, a plurality of humidifying nozzles 12 are uniformly arranged on the top of the biological packing layer 5. The outlet of the humidifying nozzle 12 faces the biological packing layer 5, and the inlet of the humidifying nozzle 12 is connected to a high-pressure submersible pump 13. The design of the humidifying nozzle 12 can further clean the clean gas rising from the biological packing layer 5, dissolve the residual odor in the gas in the water, and then fall back into the biological packing layer 5 to react with the residual deodorizing liquid in the biological packing layer 5 to further improve the effect of oxidation and deodorization.

[0035] In this embodiment, the demisting layer 6 adopts a honeycomb or corrugated packing structure, which enables water mist to be captured on the surface of the packing due to inertial collision and interception diffusion, and then eventually flow back into the biological packing layer 5.

[0036] In this embodiment, a plurality of maintenance manholes 14 are uniformly arranged on the tower body 1, and a maintenance layer is provided inside the tower body 1 at the height of the maintenance manholes 14.

[0037] In this embodiment, a level gauge 15 is provided on the tower body 1 to detect the liquid level of the biological deodorizing liquid filter layer 4, so as to facilitate the replenishment of biological deodorizing liquid at any time.

[0038] Example 2:

[0039] During operation, the odorous gas enters the gas distribution layer 2 through the air inlet 10 of the tower body 1. Through the design of the main gas distribution pipe 8 and branch gas distribution pipes 9, it is evenly dispersed within the gas distribution layer 2 and then uniformly enters the nano-microbubble generator 3. After forming nano-sized bubbles, these bubbles enter the biological deodorizing liquid filter layer 4, where they come into full contact with the biological deodorizing liquid, undergoing an oxidation reaction. Some of the toxic substances in the odorous gas are oxidized and retained, while the clean gas continues to rise. Some of the nano-sized bubbles continue to mix with the biological deodorizing liquid, creating a further osmosis under pressure. Under the action of the gas, the gas enters the biological packing layer 5 and continues to be fully oxidized. Toxic substances are trapped in the biological packing layer 5. A small amount of unoxidized odorous gas rises to the top of the biological packing layer 5 and dissolves in the water sprayed by the humidifying nozzle 12. The gas then flows back into the biological packing layer 5 to continue oxidation. Finally, the clean gas enters the demisting layer 6 under the action of gas pressure. The liquid that is carried to the top by the high-pressure gas is further trapped in the demisting layer 6. Finally, the clean gas is discharged from the tower 1 through the gas outlet 7 at the top of the tower 1, and the entire oxidation and deodorization process is completed.
