Description

Technical Field

[0001] The present invention relates to the technical field of tail gas treatment, and specifically, it is a tail gas purification device for a biopharmaceutical fermentation tank. Background Technique

[0002] In the field of biopharmaceuticals, with the continuous expansion of the industry scale and the continuous innovation of technology, the fermentation process has become one of the core links. However, the tail gas generated during the operation of the fermentation tank contains complex and diverse pollutants, including gaseous metabolites such as volatile organic compounds (VOCs), ammonia, hydrogen sulfide, and potentially escaped microorganisms. If these pollutants are directly discharged without effective treatment, they will cause serious damage to the ecological environment, threaten the health of surrounding residents, and also do not meet the requirements of increasingly strict environmental protection regulations.

[0003] In the existing tail gas purification technology for biopharmaceutical fermentation tanks, the spraying method has been widely used due to its relatively simple equipment structure, convenient operation, and strong treatment capacity. Its basic principle is to spray the washing liquid in the form of a mist through a nozzle, and make full contact with the tail gas to achieve the absorption and removal of pollutants in the tail gas. However, some problems that need to be solved urgently have emerged in the actual application of the traditional spraying method, which seriously restricts its purification efficiency and reliability. On the one hand, there are defects in the nozzle design of the traditional spraying system. Due to the limited spraying range of the nozzle, the contact area and time between the spraying liquid and the tail gas are small, and the pollutants in the tail gas cannot be fully absorbed, affecting the purification effect. On the other hand, the spraying pipeline system is prone to blockage during long-term operation. This is because the tail gas often contains some solid particles or microbial impurities, which are easy to accumulate in the spraying pipe, especially forming blockages at the nozzle part. Once the spraying pipe is blocked, it will directly affect the normal spraying of the spraying liquid, resulting in the ineffective progress of the tail gas purification process, increasing the maintenance frequency and difficulty of the equipment, reducing production efficiency, and increasing production costs.

[0004] In view of the above problems, this application document provides a tail gas purification device for a biopharmaceutical fermentation tank. Summary of the Invention

[0012] Further, a spiral blade is fixed on the inner wall of the spraying tank. The outer peripheral side of the spiral blade is fixed to the inner wall of the spraying tank. The spiral blade is located between the packing disc and the gas inlet pipe.

[0013] Further, the other end of the drain pipe penetrates into the interior of the liquid storage tank.

[0023] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0024] A tail gas purification device for a biopharmaceutical fermentation tank provided in this embodiment is mainly used to solve some urgent problems exposed in the actual application process of the traditional spraying method, which seriously restricts its purification efficiency and reliability. On the one hand, there are defects in the design of the nozzles in the traditional spraying system. Due to the limited spraying range of the nozzles, the contact area and time between the spraying liquid and the tail gas are small, and the pollutants in the tail gas cannot be fully absorbed, affecting the purification effect. On the other hand, the spraying pipeline system is prone to blockage during long-term operation. This is because the tail gas often contains some solid particulate matters or microbial impurities, and these impurities are easy to accumulate in the spraying pipeline, especially forming blockage at the nozzle part. Once the spraying pipeline is blocked, it will directly affect the normal spraying of the spraying liquid, resulting in the ineffective progress of the tail gas purification process, increasing the maintenance frequency and difficulty of the equipment, reducing the production efficiency, increasing the production cost, and providing the following technical solutions, which will be combined with Figures 1-8 be described in detail below: Embodiment

[0025] A tail gas purification device for a biopharmaceutical fermentation tank includes a spray tank 1, a spray mechanism 2, a packing mechanism 3 and an anti-blocking mechanism 4, wherein: An air outlet pipe 11 is arranged at the top of the spray tank 1 for discharging the tail gas after purification treatment from the device. An air inlet pipe 12 is constructed on the outer peripheral side of the spray tank 1 near the bottom end for introducing the tail gas generated by the biopharmaceutical fermentation tank into the device for purification treatment. A drain pipe 13 is arranged at the bottom of the spray tank 1 for discharging the waste water generated during the spraying process; The spraying mechanism 2 includes a liquid storage tank 21, a spraying assembly 22, and a liquid delivery pipe 23. The liquid storage tank 21 is arranged on one side of the spraying tank 1, and a liquid inlet pipe 211 is constructed at the top. The liquid storage tank 21 is used to store the washing liquid required for spraying, and the liquid inlet pipe 211 facilitates the replenishment of the washing liquid. The spraying assembly 22 is arranged inside the spraying tank 1 and between the gas outlet pipe 11 and the gas inlet pipe 12, ensuring that the tail gas passes through the spraying area during the rising process and fully reacts with the spraying liquid in contact. The liquid delivery pipe 23 is connected between the liquid storage tank 21 and the spraying assembly 22, and transports the washing liquid in the liquid storage tank 21 to the spraying assembly 22 to provide power support for spraying; The packing mechanism 3 is arranged inside the spraying tank 1 and between the spraying assembly 22 and the gas inlet pipe 12; The number of the anti-blocking mechanisms 4 is two, and they are respectively installed inside the drain pipe 13 and inside the liquid delivery pipe 23.

[0026] In the present invention, by adding the packing mechanism 3, the contact area and time between the spraying liquid and the tail gas are significantly increased, thereby enhancing the tail gas purification efficiency. The design of the anti-blocking mechanism 4 effectively filters out solid particulate matters or microbial impurities in the tail gas, preventing these impurities from entering the spraying pipeline system and accumulating and blocking in the pipeline.

[0027] Further, please refer to Figure 2 and Figure 6 , the spraying assembly 22 includes a circulating pipe rack 221 horizontally fixed on the inner wall of the spraying tank 1. A number of uniformly distributed atomizing nozzles 222 are installed at the bottom of the circulating pipe rack 221, and all of them are connected to the inside of the circulating pipe rack 221, ensuring that the washing liquid can be evenly sprayed out from each atomizing nozzle 222. One end of the liquid delivery pipe 23 is connected to the circulating pipe rack 221, responsible for accurately transporting the washing liquid in the liquid storage tank 21 to the circulating pipe rack 221 to provide a stable liquid supply for the spraying operation; By uniformly distributing a plurality of atomizing nozzles 222 at the bottom of the circulating pipe rack 221, the spraying range of the nozzles is significantly expanded, enabling the spraying liquid to more evenly cover the entire spraying area, effectively solving the problems of small contact area and limited time caused by the limited spraying range of traditional nozzles, thereby improving the tail gas purification efficiency.

[0028] Specifically, a water pump 212 is arranged at the top of the liquid storage tank 21. The liquid inlet end of the water pump 212 is connected with a liquid suction pipe 213 penetrating into the inside of the liquid storage tank 21, and the liquid outlet end of the water pump 212 is fixedly connected with the other end of the liquid delivery pipe 23; During the operation of the device, after the water pump 212 is started, the washing liquid is pumped from the inside of the liquid storage tank 21 through the liquid suction pipe 213. Subsequently, under the action of the water pump 212, the pumped washing liquid is transported along the liquid delivery pipe 23 to the circulation pipe rack 221 in the spray assembly 22. Finally, the washing liquid is sprayed out through the atomizing nozzles 222 evenly distributed at the bottom of the circulation pipe rack 221, forming a uniform spray layer to achieve the purification treatment of the tail gas.

[0029] It should be noted that, please refer to Figure 2 、 Figure 5 and Figure 7 . A servo motor 214 with a horizontally arranged output end is fixedly installed on one of the vertical sides of the liquid storage tank 21. The output end of the servo motor 214 movably penetrates into the inside of the liquid storage tank 21 and is fixed with a rotating rod 215. A number of uniformly distributed stirring blades 216 are fixed on the rotating rod 215. During the operation of the device, when it is necessary to stir the washing liquid in the liquid storage tank 21, the servo motor 214 is started. The output end of the servo motor 214 drives the rotating rod 215 to rotate, and then the stirring blades 216 fixed on the rotating rod 215 fully stir the washing liquid in the liquid storage tank 21. This process ensures the uniform mixing of the washing liquid, improves the purification effect of the washing liquid, and provides good liquid conditions for the subsequent spraying operation. The servo motor 214 drives the rotating rod 215 and the stirring blades 216 to fully stir the washing liquid in the liquid storage tank 21, ensuring the uniform mixing of the washing liquid, avoiding the fluctuation of the purification effect caused by uneven liquid components, and improving the stability and reliability of the tail gas purification.

[0030] In this embodiment, please refer to Figure 2 、 Figure 3 and Figure 7 . The packing mechanism 3 includes two positioning rings 31 symmetrically installed on the inner wall of the spray tank 1 up and down. A packing disk 32 is movably installed between the two positioning rings 31 and can rotate. A vertical and coaxial linkage rod 33 is fixed to the bottom of the packing disk 32. A first bevel gear 34 is fixedly sleeved on the linkage rod 33. A horizontally arranged driving rod 35 is rotatably installed on the inner wall of the spray tank 1. A second bevel gear 36 meshing with the first bevel gear 34 is fixed to one end of the driving rod 35. The other end of the driving rod 35 movably penetrates the spray tank 1 and is fixedly sleeved with a driven wheel 37. The other end of the rotating rod 215 movably penetrates the liquid storage tank 21 and is fixedly sleeved with a driving wheel 217. A unified linkage belt 38 is sleeved between the driving wheel 217 and the driven wheel 37. During the operation of the device, when the servo motor 214 in the liquid storage tank 21 starts, it drives the rotating rod 215 to rotate. The rotation of the rotating rod 215 is transmitted to the driving rod 35 through the transmission of the driving wheel 217, the connecting belt 38 and the driven wheel 37. The rotation of the driving rod 35 further drives the connecting rod 33 to rotate through the meshing transmission of the second bevel gear 36 and the first bevel gear 34. The rotation of the connecting rod 33 enables the packing disc 32 to rotate stably under the constraint of the positioning ring 31. The rotation of the packing disc 32 promotes the full contact and mixing of gas and liquid in the packing layer, enhances the mass transfer effect between the tail gas and the spraying liquid, and improves the tail gas purification efficiency. [[ID=!]]

[0031] Even further, please refer to Figure 2 、 Figure 4 and Figure 8 , the other end of the drain pipe 13 penetrates into the interior of the liquid storage tank 21. Sockets are formed on the top sides of both the drain pipe 13 and the liquid supply pipe 23. The sockets are in the shape of a semi-circular ring plate. The anti-blocking mechanism 4 includes an aggregate pipe 41 movably inserted into the socket. The diameter of the aggregate pipe 41 is the same as the inner diameter of the drain pipe 13 or the liquid supply pipe 23, ensuring that its outer peripheral side wall is in close contact with the inner wall of the drain pipe 13 or the liquid supply pipe 23. The outer peripheral side wall of the aggregate pipe 41 is in contact with the inner wall of the drain pipe 13 or the liquid supply pipe 23. A filter screen 42 is fixed to one end of the aggregate pipe 41. The filter screen 42 is located at the end of the aggregate pipe 41 that contacts the liquid later, and is used to filter solid particulate matter or microbial impurities in the washing liquid. An arc plate 43 is fixed to the outer peripheral side of the aggregate pipe 41. When the aggregate pipe 41 is movably inserted into the inner wall of the drain pipe 13 or the liquid supply pipe 23, the arc plate 43 is inserted into the socket and fits exactly. The length of the arc plate 43 is greater than the length of the aggregate pipe 41, and an adsorption magnet 44 is fixed on the open side of the arc plate 43. A fixing groove is formed on the drain pipe 13 or the liquid supply pipe 23, and an iron sheet is arranged on the inner wall of the fixing groove. The adsorption magnet 44 is movably inserted into the fixing groove and magnetically adsorbed to the iron sheet to ensure the stable installation of the aggregate pipe 41. A clamping groove 431 is formed on the outer side of the arc plate 43 in contact with the socket, and a sealing strip 432 is embedded in the clamping groove 431 to further enhance the sealing effect; During the operation of the device, when the waste water flows into the liquid storage tank 21 through the drain pipe 13, it passes through the filter screen 42 at one end of the aggregate pipe 41, and the impurities are effectively intercepted to prevent them from entering the spray pipeline system and accumulating and blocking in the pipe. At the same time, when the liquid supply pipe 23 supplies liquid into the interior of the circulation pipe rack 221, it can also intercept solid particles to avoid blocking the atomizing nozzles 222. When it is necessary to maintain and clean the aggregate pipe 41, the operator can use tools to overcome the magnetic adsorption force between the adsorption magnet 44 and the iron sheet, and pull out the aggregate pipe 41 from the drain pipe 13 or the liquid supply pipe 23 to clean the impurities accumulated on the filter screen 42. After cleaning, insert the aggregate pipe 41 back into the socket to ensure that the arc plate 43 is in close contact with the socket, and the adsorption magnet 44 is magnetically adsorbed and fixed to the iron sheet to ensure the normal operation of the device. Example

[0032] Example 2 is a further optimization of Example 1. Please refer to Figure 3 , on the opposite sides of the two positioning rings 31, a number of uniformly distributed rolling balls 311 are spherically connected. The upper and lower sides of the packing disk 32 are in rolling connection with a number of rolling balls 311. By arranging the rolling balls 311 on the positioning rings 31 and making the packing disk 32 in rolling connection with the rolling balls 311, the frictional resistance during the rotation of the packing disk 32 is effectively reduced, the energy consumption of the equipment is reduced, and the operation efficiency of the equipment is improved. Example

[0033] Example 3 is a further optimization of Example 1. Please refer to Figure 2 , a spiral blade 14 is fixed on the inner wall of the spray tank 1. The outer peripheral side of the spiral blade 14 is fixed to the inner wall of the spray tank 1. The spiral blade 14 is located between the packing disk 32 and the air inlet pipe 12. The arrangement of the spiral blade 14 effectively improves the flow state of the tail gas in the spray tank 1, enables the tail gas to be more evenly distributed before entering the packing disk 32, avoids the problem of poor local purification effect caused by uneven air flow distribution, improves the uniformity and efficiency of the tail gas purification in the entire spray tank 1. Through the guidance of the spiral blade 14, the flow path of the tail gas in the spray tank 1 is extended, and the contact time between the tail gas and the spray liquid is increased. This is conducive to the pollutants in the tail gas reacting more fully with the spray liquid, further improving the effect of tail gas purification, especially having a better treatment effect on some pollutants that are difficult to absorb quickly.

[0034] The specific operation process of this equipment is as follows: First, turn on the servo motor 214 and the water pump 212. The servo motor 214 drives the rotating rod 215 to rotate, and then the stirring blade 216 fixed on the rotating rod 215 fully stirs the washing liquid in the liquid storage tank 21 to ensure the uniform mixing of the washing liquid and improve its purification effect. At the same time, the water pump 212 extracts the washing liquid from the liquid storage tank 21 through the liquid suction pipe 213 and transports it to the circulation pipe rack 221 in the spray assembly 22 through the liquid delivery pipe 23. The atomizing nozzles 222 uniformly distributed at the bottom of the circulation pipe rack 221 spray the washing liquid into fine droplets to form a uniform spray layer, preparing to purify the tail gas; Then, the tail gas generated by the biopharmaceutical fermentation tank enters the spray tank 1 through the air inlet pipe 12. During the upward movement, the tail gas first passes through the spiral blade 14 on the inner wall of the spray tank 1. The spiral blade 14 optimizes the flow state of the tail gas, and the air flow is more evenly distributed across the cross-section of the entire spray tank 1, avoiding the situation of local air flow concentration or uneven distribution, creating good conditions for subsequent purification treatment; Then, the tail gas continues to rise and passes through the packing mechanism 3. The packing trays 32 in the packing mechanism 3 rotate regularly under the action of the transmission device, enabling the tail gas to be evenly distributed in the packing layer and come into full contact with the spraying liquid. The atomized washing liquid sprayed by the spraying assembly 22 contacts the tail gas countercurrently, and mass transfer and chemical reactions occur between the gas and the liquid. The pollutants in the tail gas are absorbed by the washing liquid, thereby achieving the purification of the tail gas. During this process, the rotation of the packing trays 32 promotes the full contact and mixing of the gas and the liquid in the packing layer, enhances the mass transfer effect between the tail gas and the spraying liquid, and further improves the tail gas purification efficiency; The purified tail gas continues to rise and finally is discharged from the device through the air outlet pipe 11. The wastewater generated during the spraying process flows into the liquid storage tank 21 through the drain pipe 13. In the liquid storage tank 21, the wastewater is mixed with the fresh washing liquid, and after being fully stirred by the stirring blades 216, it is pumped out again by the water pump 212 for recycling, realizing the recycling of the washing liquid and reducing the waste of water resources and the discharge of wastewater; During the operation of the device, the filter screen 42 at one end of the collecting pipe 41 in the drain pipe 13 and the liquid supply pipe 23 effectively intercepts the solid particulate matter or microbial impurities mixed in the tail gas and the wastewater, preventing these impurities from entering the spraying pipeline system and accumulating and blocking in the pipes. This not only ensures the normal spraying of the spraying liquid, reduces the maintenance frequency and difficulty of the device, but also improves the production efficiency and reduces the production cost.

[0035] It should be particularly noted that the specific model specifications of the water pump 212 and the servo motor 214 need to be selected and determined according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail. Moreover, the principles of these components are clear to those skilled in the art and do not need to be elaborated in detail here.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
