Description

A biological fermentation tail gas treatment device

Technical Field

The present invention mainly relates to the technical field of tail gas treatment devices, and in particular to a biological fermentation tail gas treatment device.

Background Art

With the rapid development of modern biotechnology, bio-fermentation products have become one of the industries with the most active investment and the fastest development. Medicines, foods, and fine chemicals prepared by bio-fermentation are widely used in medicine, chemical industry, and daily life, making great contributions to human health. Bio-fermentation has become a powerful means and tool for the industrialization of bio-fermentation products. In the process of bio-fermentation, the use of air is indispensable for the growth of microorganisms, and the amount of air used is large, generally 0.5-1.2VVM. However, a large amount of air not used by microorganisms needs to be discharged into the atmosphere with the exhaust gas discharged from the fermentation tank, so that part of the fermentation metabolites produced by microbial growth are carried out of the fermentation tank with the exhaust gas and discharged into the surrounding air. Since the metabolites produced by microbial growth usually have a certain smell and taste, they will have a certain impact on the surrounding environment. Therefore, the fermentation exhaust gas needs to be treated before discharge.

For example, Chinese patent publication number CN108211638B discloses a microbial fermentation tail gas treatment device, including a frame, one end of the frame is provided with an air suction device, vertical plates and partitions are clamped in the frame, the frame is divided into a solid-liquid separation chamber, a reaction chamber and a filter chamber by the vertical plates and partitions, one end of the solid-liquid separation chamber is provided with a spraying device, the other end of the solid-liquid separation chamber is provided with a collecting box, a heating device is provided in the vertical plate, a shell is slidably connected in the reaction chamber, and a horizontal plate is fixedly connected to one side of the shell.

The above application has a simple structure and is easy to operate. The cam, the movable block, and the first spring rod can drive the shell and the reaction box to move back and forth, thereby generating vibrations. First, it can accelerate the absorption of the bottom side of the soluble gas in the exhaust gas, and second, it can make it fully react. Through the interaction of the push block and the card block, various filters can be easily installed and disassembled. However, as impurities accumulate on the filter, the pores of the filter will gradually be blocked, resulting in obstruction of air circulation and reducing the filtration efficiency of the filtration system. Therefore, the filter needs to be maintained and cleaned. The filter in the prior art is maintained and cleaned manually, which not only requires the disassembly of multiple parts, but also requires manual cleaning, which is complicated to operate.

Working principle:

In this embodiment, the first filter 53, the second filter 54 and the third filter 55 can be cleaned with a cleaning brush 64, while the fourth filter 51 and the fifth filter 56 cannot be cleaned. The positions of the first filter 53, the second filter 54, the third filter 55, the fourth filter 51 and the fifth filter 56 can be replaced according to actual conditions. For example, the primary filter is usually made of a metal mesh or a synthetic fiber material, such as polyester or polyimide fiber, and is used to capture larger particles. For example, the medium-efficiency filter is used to capture smaller particles, such as viruses, bacteria and some organic substances. The medium-efficiency filter is usually made of synthetic fibers such as polyester or nylon, and is made of a spunbond method or a melt-blown method. The primary filter and the medium-efficiency filter can generally be brushed and can be reused after cleaning. However, high-efficiency filters such as HEPA (high-efficiency particulate air) filters, made of synthetic fibers such as polypropylene or polyester, are very effective in capturing particles larger than 0.3 microns. It is generally not recommended to brush HEPA filters. Activated carbon filters are made of activated carbon particles or powder combined with supporting materials to adsorb organic vapors, odors and harmful gases in exhaust gas. It is generally not recommended to brush activated carbon filters. The photocatalytic oxidation (PCO) layer uses a specific catalyst, such as titanium dioxide (TiO2) or vanadium titanium dioxide, to oxidize and decompose organic pollutants in exhaust gas under the action of ultraviolet light. Physical cleaning of the photocatalytic oxidation layer is generally not recommended because the activity of the catalyst may be reduced due to mechanical damage. Staff can use different filter materials according to actual conditions or use the same filter material to achieve filtering effects of different diameters.

The exhaust gas generated by the fermentation tank 1 passes through the shell and tube heat exchanger 2, the cyclone separator 3 and the filter module in sequence. The shell and tube heat exchanger 2 can reduce the temperature of the exhaust gas from the fermentation tank 1, reduce the heat impact in the subsequent treatment process, and also help prevent certain harmful substances from having adverse reactions at high temperatures. The cyclone separator 3 is mainly used to separate solid particles in the exhaust gas, separate these solid particles from the airflow, reduce the load of subsequent treatment, and also prevent solid particles from polluting the environment. By setting a multi-stage filter screen of the filter module, namely the first filter screen 53, the second filter screen 54, the third filter screen 55, the fourth filter screen 51 and the fifth filter screen 56, it is possible to effectively capture fine particles and suspended matter in the exhaust gas, while absorbing the odor in the exhaust gas, thereby improving the cleanliness of the exhaust gas treatment.

When the first filter 53 , the second filter 54 and the third filter 55 need to be replaced, the three mounting frames 702 are extended by the lifting assembly. The arrangement of the card slots 703 facilitates the installation and removal of the first filter 53 , the second filter 54 and the third filter 55 .

When cleaning operations are required, the output end of the first electric push rod 622 pushes the movable plate 621 to move upward or downward along the guide rail 627. The movement of the movable plate 621 drives the rack 625 to make a linear motion, and through the engagement with the first gear 624, the linear motion is converted into a rotational motion, and the installation shaft 63 is driven to rotate through the connecting head 623. In this embodiment, the installation shaft 63 rotates back and forth 180°. The driving component 62 drives the two mounting shafts 63 to rotate back and forth through the output end. When the mounting shaft 63 rotates, the cleaning brush 64 thereon also rotates accordingly. The cleaning brush 64 cleans the outer surfaces of the first filter 53, the second filter 54 and the third filter 55. The cleaning soft claws 642 scrape off impurities attached to the first filter 53, the second filter 54 and the third filter 55 in the exhaust gas. When the mounting shaft 63 drives the cleaning brush 64 to rotate back and forth, the cleaning brush 64 collides with the collision rod 65 to shake the impurities in the dust scraping groove 643 into the dust accumulation groove 84. The design of the cleaning brush 64 can effectively remove impurities such as impurities and dirt attached to the filter, ensure the cleanliness of the filter, extend its service life, and thereby realize automatic cleaning of the outer surfaces of the first filter 53, the second filter 54 and the third filter 55.

The impurities cleaned by the cleaning brush 64 will first fall into the dust storage groove 84. After leaving the cleaning brush 64, the impurities will first be collected and concentrated, which reduces the contamination of other components in the installation cavity 44 by the impurities, and also facilitates the subsequent cleaning work. The design of the dust suction hole 87 between the dust storage groove 84 and the branch pipe installation groove 85 allows the impurities to be sucked into the dust suction branch pipe 81 through the dust suction hole 87 while falling into the dust storage groove 84. The dust suction branch pipe 81 set in the branch pipe installation groove 85 is responsible for transmitting the sucked impurities from the dust storage groove 84 to the dust suction main pipe 82. The dust suction main pipe 82 is then connected to the dust collector 83, and finally the impurities are sucked away by the dust collector 83. The impurities are sucked away by the dust suction component 8, which further ensures the overall cleaning effect and reduces the residual impurities.

The lifting component can simultaneously drive the three second rack shafts 714 to move synchronously through the second electric push rod 713, thereby driving the third gear 711 to rotate through the second gear 710 and the rotating shaft 709, so that the second gear 710 and the third gear 711 on the three rotating shafts 709 rotate synchronously, and the third gear 711 drives the first rack shaft 707 to move up and down, thereby adjusting the height of the mounting frame 702 and the first filter screen 53, the second filter screen 54 and the third filter screen 55 on the mounting frame 702, thereby realizing the simultaneous adjustment of the heights of multiple filter screens, ensuring the consistency and efficiency of the operation, and facilitating the cleaning component 6 to be able to comprehensively and effectively clean the filter screen. By accurately adjusting the height of the filter screen, the cleaning component 6 can better contact various parts of the filter screen, thereby improving the cleaning effect, ensuring the filtering performance of the filter screen, and extending the service life of the filter screen.

The components of the present invention work together to achieve comprehensive and efficient cleaning of the filter screen, while reducing manual intervention and improving cleaning efficiency.

The above-described embodiments only express a certain implementation mode of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the patent scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
