Description

Technical Field

[0001] The utility model relates to the field of inorganic waste gas treatment, in particular to an energy-saving inorganic waste gas treatment biological deodorization filter tank. Background Art

[0002] The biological deodorization filter used in inorganic waste gas treatment is mainly an environmental protection equipment that uses the physiological activities of microorganisms to convert harmful substances in waste gas into harmless substances. The biological deodorization filter uses biological fillers as carriers to allow microorganisms to form biofilms on the surface of biological fillers under a suitable environment. These microorganisms use inorganic substances in 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, thereby achieving the purpose of purifying odorous gases.

[0003] After searching, Chinese patent announcement number: CN114392644A discloses a biological deodorization filter for treating inorganic waste gas, including a machine, an air inlet pipe, a base, a biological filter, a first spray component, a filter layer support plate, a purification component, a second spray component, an exhaust pipe and an air primary filter. By starting the fan, the external waste gas is sucked into the interior of the air inlet pipe and injected into the interior of the biological filter. The first spray component is then started to spray the waste gas to achieve a partial purification effect. As the gas moves upward and reaches the purification component, the purification effect is enhanced. When it rises to the top of the biological filter, the second spray component is started to assist the purification component and enhance the deodorization effect. Subsequently, it is filtered again through the air primary filter provided at the exhaust pipe, thereby enhancing the purification effect.

[0004] Although this technical solution can quickly process inorganic waste gas through the filter, in actual use, the gas is directly injected into the biological filter through the fan, and the gas will form large bubbles in the filter, which cannot be evenly distributed in the filter. At the same time, the fan will provide the gas with an initial kinetic energy, so that the gas moves upward quickly and passes through the filter, resulting in too little contact area between the gas and the filter, too short a contact time, and poor reaction effect. Therefore, an energy-saving inorganic waste gas treatment biological deodorization filter is proposed to solve the above problems. Utility Model Content

[0021] 2. In the utility model, by setting a filter, the gas is turned into fine bubbles, which increases the area for reaction with microorganisms.

When no air intake is required, the valve is closed. When inorganic waste gas treatment is required, inorganic waste gas is pumped into the air inlet 2 by using an air pump, and then the valve is opened under a certain air pressure to pass inorganic waste gas into the treatment tank 1. The inner wall of the bottom end of the treatment tank 1 is fixedly connected with a fixed A fixed bracket 3 with a connecting function, the top of the fixed bracket 3 is rotatably connected to a rotating component, the rotating component is used to provide rotational power, the rotating component includes a rotating shaft 5, the bottom of the rotating shaft 5 is rotatably connected to the top of the fixed bracket 3, the outer periphery of the rotating shaft 5 is fixedly connected to fan blades 4, the fan blades 4 are arranged in several groups, and are evenly distributed in a ring shape on the outer periphery of the rotating shaft 5, the rotating shaft 5 and the fan blades 4 are located directly above the air inlet 2, when the air pump pumps the inorganic waste gas into the treatment tank 1 through the air inlet 2, the gas will push the fan blades 4 to rotate, and the fan blades 4 will drive the rotating shaft 5 to rotate.

[0030] Reference Figure 2-Figure 3 A worm 6 is fixedly connected to the top of the rotating assembly, and the top of the rotating shaft 5 is fixedly connected to the bottom of the worm 6. When the rotating shaft 5 rotates, the worm 6 is driven to rotate. A worm wheel 7 is meshed on the outside of the worm 6. When the worm 6 rotates, the worm wheel 7 is driven to rotate. At the same time, the worm wheel 7 converts the rotation direction of the worm 6 from horizontal to vertical. Two groups of worm wheels 7 are provided, and the two groups of worm wheels 7 are symmetrically arranged. A rotating shaft 8 is fixedly connected inside the worm wheel 7, and a stirring blade 9 is fixedly connected to the outer periphery of the rotating shaft 8. When the stirring blade 9 rotates, the gas flushed into the water can be dispersed to make it evenly distributed. The rotating shaft 8 is rotatably connected to a rotating bracket 10 on both the front and rear sides for fixed support. The bottom end of the rotating bracket 10 is rotatably connected to the outer periphery of the rotating shaft 5. The bottom of the rotating bracket 10 is fixedly connected to a support column 11 for fixed support. Two groups of support columns 11 are provided, which are symmetrically arranged at the bottom of the rotating bracket 10. The bottom of the support column 11 is fixedly connected to the inner wall of the bottom end of the processing tank 1. A filter component is fixedly connected inside the processing tank 1. The filter component is used to treat exhaust gas. An exhaust port 16 is provided at the top of the processing tank 1 to discharge the treated odorless gas.

[0031] Reference Figure 2 and Figure 4The filter assembly includes a filter screen 12, and fine holes are opened on the surface of the filter screen 12. When the gas rises, it passes through the filter screen 12 and can turn the gas into fine bubbles. The filter screen 12 is fixedly connected to the inside of the treatment pool 1. The filter screen 12 is provided with two groups, which are symmetrically arranged up and down. A baffle 13 is fixedly connected to the inside of the treatment pool 1. The baffle 13 is located in the middle of the two groups of filter screens 12. The baffle 13 is provided with two groups. One group of baffles 13 is fixedly connected to the inner wall of the left side of the treatment pool 1, and the right side does not contact the inner wall of the treatment pool 1 to form a channel for gas to pass through. The other group of baffles 13 is fixedly connected to the inner wall of the right side of the treatment pool 1, and the left side is in contact with the treatment pool 1. The inner wall of the pool 1 is not in contact, forming a channel for gas to pass through. A bioreactor frame 14 is fixedly connected to the inner side of the baffle 13. The bioreactor frame 14 can accommodate gas and liquid to pass through, but microorganisms used for reaction cannot pass through. Active microorganisms for treating the odor of inorganic waste gas are placed inside. A partition frame 15 is fixedly connected inside the bioreactor frame 14 to divide the inside of the bioreactor frame 14 into multiple cavities, so that the microorganisms cannot be enriched in a certain area inside the bioreactor frame 14, so that they are evenly distributed. The partition frame 15 can accommodate gas and liquid to pass through, but microorganisms used for reaction cannot pass through.

[0032] Working principle: when you want to make the inorganic waste gas entering the treatment pool 1 evenly distributed, use an air pump to discharge the inorganic waste gas through the air inlet 2. At this time, the inorganic waste gas passes through the fan blades 4, which will drive the fan blades 4 to rotate. The rotation of the fan blades 4 can not only disperse the internal gas for the first time, but also drive the rotating shaft 5 to rotate. The rotation of the rotating shaft 5 will drive the worm 6 to rotate, and the rotation of the worm 6 will drive the worm gear 7 to rotate. The rotation of the worm gear 7 will drive the rotating shaft 8 to rotate. The rotation of the rotating shaft 8 will drive the stirring blades 9 to rotate. The rotation of the stirring blades 9 will disperse the gas again, so that the gas is evenly distributed in the water body, and at the same time reduce the rising speed of the gas, so that the gas passes through the filter component more slowly and evenly. When the inorganic waste gas is to be allowed to fully react with the microorganisms, the inorganic waste gas rises and passes through the filter 12. The filter 12 divides the inorganic waste gas into fine bubbles again. The fine bubbles rise and pass through the left side of the lower baffle 13 this year to react with the microorganisms inside the bioreactor frame 14. At the same time, the upper baffle 13 allows the gas to move only to the right, across the entire bioreactor frame 14, and then pass through the right side of the upper baffle 13, and finally be discharged from the exhaust port 16, thereby increasing the reaction time and contact area with the microorganisms and improving the reaction effect.
