Description

Technical Field

[0001] The invention relates to the technical field of microbial fermentation, in particular to a microbial fermentation plant with circumferentially distributed tanks. Background Art

[0002] Microbial fermentation is a biochemical process that uses microorganisms (such as bacteria, yeast, mold, etc.) to convert organic matter into products with specific flavor, texture or function through their metabolic activities under specific conditions. It is an important part of the modern biotechnology industry and is widely used in food, medicine, chemical industry, agriculture and other fields.

[0003] In order to meet the needs of large-scale fermentation, the existing microbial fermentation workshop includes a tank body and a control room. The fermentation workshop is designed in a square shape. Figure 1 As shown, the letter H represents the seed tank, the letter A represents the fermentation tank, and the letter B represents the feeding tank. The following problems exist:

[0004] First, it occupies a large area and can accommodate fewer fermentation tanks per unit area.

[0005] Second, the length of the pipeline between the feeding tank / seed tank and the fermentation tank is high. For example, if you want to transport the liquid in the seed tank and feeding tank on the west to the fermentation tank on the east, the middle pipeline basically runs through the interior of the workshop. The excessively long pipeline not only causes the transported material to remain in the pipeline, resulting in loss of the transported material, but also if the fermentation strain needs to be replaced, not only the fermentation tank body needs to be disinfected, but also all the transport pipelines involved need to be disinfected, resulting in excessive disinfection pressure and increased fermentation costs.

[0006] Third, the fermentation tanks are arranged in the east-west direction of the workshop. When the staff need to inspect the equipment from west to east or from east to west, the time and labor costs required are high. In addition, if the connection between the pipeline and the fermentation tank input port becomes loose, when the staff walks from one fermentation tank to another, it is very likely to cause microbial contamination, resulting in fermentation failure.

[0007] Therefore, a new microbial fermentation plant with a circumferential distribution of tank bodies is urgently needed to solve the above technical problems. Summary of the Invention

[0008] The present invention aims to solve the above-mentioned technical problems, namely, to solve the following problems: First, the existing microbial fermentation workshop occupies a large area, and the number of fermentation tanks that can be accommodated per unit area is small; second, the distance between the control room and the fermentation tank is long, which is time-consuming and labor-intensive when personnel perform inspections and other operations, and easily brings the risk of contamination to other tanks; third, the length of the pipeline between the feeding tank / seed tank and the fermentation tank is long, which not only causes the conveyed material to remain in the pipeline and lead to the loss of the conveyed material, but also, if the fermentation strain needs to be replaced, not only the fermentation tank body needs to be disinfected, but also all the conveying pipelines involved need to be disinfected, resulting in excessive disinfection pressure and high fermentation costs.

[0009] To this end, the present invention provides a microbial fermentation plant with a circumferentially distributed tank body, comprising a plant body, a tank body and a studio. The plant body is a cylindrical structure, and the outer side of the central area of the plant body is surrounded by multiple layers of fermentation tank groups distributed at intervals. Each layer of the fermentation tank group includes multiple tank bodies distributed in a circle with the central area of the plant body as the center.

[0010] In the specific embodiment of the microbial fermentation plant with the tank bodies distributed circumferentially, the volume of the tank bodies of the multi-layer fermentation tank group gradually increases from the inner layer to the outer layer.

Multiple floors are arranged in the plant body, and the top of each tank is on the same floor in the plant body. The studio on the highest floor includes a control room, and the floor of the control room is higher than the floor where the top of the tank is located.

Each of the fermentation systems is equipped with a pipeline transportation system, and the pipeline transportation system includes a circulating water pipeline, a steam pipeline, a feeding pipeline and a material pipeline. The circulating water pipeline, the steam pipeline, the feeding pipeline and the material pipeline are all in an arc shape surrounding the tank bodies in the corresponding fermentation system. The steam pipeline is respectively connected to the feeding tank, the seed tank and the fermentation tank for introducing steam. The feeding tank is connected to all the fermentation tanks in the corresponding fermentation system through the feeding pipeline, and the seed tank is connected to all the fermentation tanks in the corresponding fermentation system through the material pipeline. The circulating water pipeline is used to provide circulating water to all the fermentation tanks, seed tanks and feeding tanks.

[0014] In a specific embodiment of the microbial fermentation plant with the above-mentioned tank bodies distributed in a circular pattern, the seed tank includes a primary seed tank and a secondary seed tank, and the secondary seed tank and the primary seed tank are located in a fermentation tank group on adjacent layers. The material pipeline includes a primary seed material pipeline and a secondary seed material pipeline, and the primary seed tank transports materials to all the secondary seed tanks in the fermentation system through the primary seed material pipeline, and the secondary seed tank transports materials to all the fermentation tanks in the fermentation system through the secondary seed material pipeline. The primary seed material pipeline is distributed in an arc shape between the secondary seed tank and the primary seed tank, and the secondary seed material pipeline is distributed in an arc shape between the secondary seed tank and the fermentation tank.

[0015] In a specific embodiment of the microbial fermentation plant with the above-mentioned circumferential distribution of tank bodies, the tank bodies in one part of the fermentation system are further divided into ammonia water tanks, and the tank bodies in another part of the fermentation system are further divided into defoaming agent tanks. The ammonia water tank and the defoaming agent tank are both located in the innermost fermentation tank group. The fermentation system with the ammonia water tank and the fermentation system with the defoaming agent tank are alternately distributed in the plant body. The pipeline conveying system also includes an ammonia water pipeline and a defoaming agent pipeline. The ammonia water tank conveys ammonia water to the fermentation tank through the ammonia water pipeline, and the defoaming agent tank conveys defoaming agent to the fermentation tank and the secondary seed tank through the defoaming agent pipeline. The ammonia water pipeline and the defoaming agent pipeline are both arc-shaped and arranged between two adjacent layers of fermentation tank groups. The ammonia water tank is connected to all the fermentation tanks in the fermentation system through the ammonia water pipeline, and the defoaming agent tank is connected to all the secondary seed tanks and fermentation tanks in the fermentation system through the defoaming agent pipeline.

[0016] In a specific embodiment of the above-mentioned microbial fermentation plant with a circular distribution of tank bodies, a cyclone separator is installed at the exhaust gas outlet of each fermentation tank to remove gas and carried materials to achieve gas-liquid separation, and an arc-shaped waste liquid pipe and a waste gas pipe are arranged in one layer of the plant body.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The studio is set in the central area of the plant body, and the tanks are distributed in a circle around the central area. This shortens the distance between the studio and the tanks, saving physical strength and time when personnel conduct inspections and other operations on the tanks, while also avoiding the risk of contamination of the tanks. In addition, the circular fermentation workshop can accommodate more tank equipment and increase production capacity.

[0021] 2. The largest tank is placed on the outermost layer, which is more conducive to heat dissipation. At the same time, the tanks in the plant body are divided into independent fermentation systems. Each fermentation system is equipped with a fermentation tank, a seed tank, and a feeding tank, which can achieve independent fermentation production without affecting each other, and avoid contamination of other strains during inspection by staff.

[0022] 3. By arranging the tanks in a circle and forming multiple separate fermentation systems, the length of the steam pipe, feeding pipe, material pipe, etc. is shortened, thereby reducing the consumption of fermentation materials in the pipes and the disinfection cost, thereby reducing production costs.

DETAILED DESCRIPTION

[0041] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0042] In the description of the present invention, it should be noted that the terms "upper," "lower," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate description and simplify the present invention. They are not intended to indicate or imply that the systems or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the use of terms such as "first" and "second" to define components is intended solely to facilitate distinction between such components. Unless otherwise stated, these terms have no special meanings and should not be construed as indicating or implying relative importance.

[0043] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "installed," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0044] The present invention relates to the field of microbial fermentation technology, and in particular to a microbial fermentation plant with circumferentially distributed tanks. The purpose is to solve the following problems: first, existing microbial fermentation workshops occupy a large area, but can accommodate few fermentation tanks per unit area; second, the distance between the control room and the fermentation tanks is long, which is time-consuming and labor-intensive when personnel conduct inspections and other operations, and easily poses a risk of contamination to other tanks; third, the length of the pipeline between the feed tank / seed tank and the fermentation tank is long, which not only causes the transported material to remain in the pipeline and cause loss of the transported material, but also requires disinfection of not only the fermentation tank body but also the transport pipelines involved if the fermentation strain needs to be replaced, resulting in excessive disinfection pressure and high fermentation costs. To this end, the present invention provides a microbial fermentation plant with a circularly distributed tank body, which includes a plant body, a tank body and a studio. The plant body is a cylindrical structure. The central area of the plant body forms an elevator shaft and a multi-floor studio. An elevator is installed in the elevator shaft. The multi-floor studio surrounds the elevator shaft so that the studio on each floor can be entered by the elevator. The outer side of the central area of the plant body is surrounded by multiple layers of fermentation tank groups that are distributed at intervals. Each layer of fermentation tank group includes multiple tank bodies that are distributed in a circle with the central area of the plant body as the center. The present invention sets the studio in the central area of the plant body, and the tank bodies are distributed in a circle around the central area. This shortens the distance between the studio and the tank body, saves physical strength and time when personnel perform inspections on the tank body, and also avoids the risk of contamination of the tank body. Moreover, the circular fermentation workshop can accommodate more tank equipment and improve production capacity.

[0045] The microbial fermentation plant with circumferentially distributed tanks provided by an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0046] See Figure 2-6 The present invention provides a microbial fermentation plant with a circumferential distribution of tank bodies, comprising a plant body 1, a tank body 2 and a studio. The plant body 1 is a cylindrical structure. The central area of the plant body 1 forms an elevator shaft 5 and a multi-floor studio. An elevator is installed in the elevator shaft 5. The multi-floor studio surrounds the elevator shaft 5 so that the studio on each floor can be entered by the elevator. The outer side of the central area of the plant body 1 is surrounded by multi-layer and spaced fermentation tank groups. Each fermentation tank group includes a plurality of tank bodies 2 distributed in a circle with the central area of the plant body 1 as the center.

[0047] Specifically, each studio floor can be designed with multiple workshops, each of which can be one or more of the exhaust treatment area, tool room, strain room, laboratory, control room 4, etc., and one or two workshops of the same type can also be set up. It should be noted that the type of workshop can be flexibly set according to actual conditions. Preferably, the workshops required for production, maintenance and management are set up on different floors, so that production, maintenance and management do not affect each other. For example, Figure 3 As shown, the workshop represented by letter a is the power distribution room, the workshop represented by letter b is the exhaust gas treatment area, the workshop represented by letter c is the workshop, the workshop represented by letter d is the production auxiliary room, the workshop represented by letter e is the strain room, and the workshop represented by letter f is the air-conditioning room; the workshop represented by letter g is the laboratory, the workshop represented by letter h is the auxiliary room, and the workshop represented by letter k is the process room. It can be seen from the figure that the process room is set on the highest floor, that is, on the same floor as the control room.

[0048] In one embodiment, see Figure 4-6 The volume of the tank body 2 of the multi-layer fermentation tank group gradually increases from the inner layer to the outer layer. The largest volume is set in the outermost layer, which makes it easy to radiate the heat generated by the fermentation to the outside.

[0049] In one embodiment, the plant body 1 is provided with multiple floors, and the top of each tank body 2 is located on the same floor of the plant body 1. The studio on the highest floor includes a control room 4, and the floor of the control room 4 is higher than the floor where the top of the tank body 2 is located. Figure 3 As shown, the position is higher than the tank 2, which allows for intuitive monitoring and control of the tank 2. The studio on the highest floor also includes an enclosed viewing passage 3, which is a ring-shaped structure surrounding the outside of the elevator shaft 5 for viewing the distribution of each tank 2 in the plant body 1.

[0050] Specifically, the side of the viewing passage 3 facing the interior of the plant body 1 is made of glass, which facilitates viewing. The viewing passage 3 is designed to be annular, i.e., it circumscribes the entire plant, allowing visitors to directly observe the layout of the various tanks 2, providing a wider field of view without touching the tanks 2, thus preventing contamination of the fermentation tanks by microorganisms carried by visitors. Furthermore, this floor is lower than the floor where the viewing passage 3 is located, making it easier to observe the distribution of the tanks 2 through the viewing passage 3.

[0051] For example, Figure 3 As shown, the plant building 1 has four floors for installing tanks 2. The tanks 2 vary in height. The tallest tanks 2 are installed from the first to the fourth floor, while the lower tanks 2 can be installed from the second to the fourth floor, or from the third to the fourth floor, depending on their height. Ultimately, the tops of the tanks 2 are all on the fourth floor. A pressure detector and opening are located on the top floor of the tanks 2, allowing staff to monitor and operate the tanks 2 from above. The studio has six floors, with a control room 4 and a viewing corridor 3 located on the top floor.

[0052] In one embodiment, a first lighting and ventilation skylight 6 is provided in the central area of the roof of the factory building, and two symmetrically distributed second lighting and ventilation skylights 7 are provided on the roof around the first lighting and ventilation skylight for lighting, ventilation and heat dissipation inside the factory building 1.

[0053] In one embodiment, see Figure 4-6 The tank bodies 2 in the main body of the plant 1 are combined to form a plurality of independent fermentation systems, and each fermentation system includes part of the tank bodies 2 in each layer. The angle between two adjacent tank bodies 2 on the same layer in each fermentation system can be 17.3°. Each fermentation system can carry out microbial fermentation independently, can carry out fermentation of the same microorganisms, and can also carry out fermentation of different microorganisms. It should be noted that this application does not make any specific limitation on the angle between adjacent tank bodies 2, and it can be flexibly set according to actual conditions without deviating from the basic principles of the present invention.

[0054] For example, the plant is divided into four quadrants according to the quadrant division principle, and are arranged in a counterclockwise direction as the first quadrant, the second quadrant, the third quadrant and the fourth quadrant, and a fermentation system is set in each quadrant.

[0055] In the above embodiment, each fermentation system can ferment different or the same microorganisms. Since the fermentation systems are independent of each other, the problem of mutual contamination is avoided.

[0056] In one embodiment, see Figure 4-6 The tank body 2 in the fermentation system is divided into a feeding tank B, a seed tank and a fermentation tank A. The fermentation tank A is in a fermentation tank group on different layers from the feeding tank B and the seed tank. Each fermentation system is equipped with a pipeline transportation system. The pipeline transportation system includes a circulating water pipeline 11, a steam pipeline 8, a feeding pipeline 26 and a material pipeline. The circulating water pipeline 11, the steam pipeline 8, the feeding pipeline 26 and the material pipeline are all arc-shaped and surround the tank body 2 in the corresponding fermentation system. The steam pipeline 8 is respectively connected to the feeding tank, the seed tank and the fermentation tank for introducing steam. The feeding tank is connected to all the fermentation tanks in the corresponding fermentation system through the feeding pipeline 26. The seed tank is connected to all the fermentation tanks in the corresponding fermentation system through the material pipeline. The circulating water pipeline 11 is used to provide circulating water to all fermentation tanks, seed tanks and feeding tanks.

[0057] Specifically, the seed tank includes a first-level seed tank D and a second-level seed tank C. The second-level seed tank C and the first-level seed tank D are located in the fermentation tank group on adjacent layers. The material pipeline includes a first-level seed material pipeline 24 and a second-level seed material pipeline 22. The first-level seed tank transports materials to all the second-level seed tanks in the fermentation system through the first-level seed material pipeline 24, and the second-level seed tank transports materials to all the fermentation tanks in the fermentation system through the second-level seed material pipeline 22. The first-level seed material pipeline 24 is distributed in an arc shape between the second-level seed tank and the first-level seed tank, and the second-level seed material pipeline 22 is distributed in an arc shape between the second-level seed tank and the fermentation tank.

[0058] In one embodiment, the tank body 2 in one part of the fermentation system is further divided into an ammonia water tank, and the tank body 2 in another part of the fermentation system is further divided into a defoaming agent tank. The ammonia water tank and the defoaming agent tank are both located in the innermost fermentation tank group. The fermentation system with the ammonia water tank and the fermentation system with the defoaming agent tank are alternately distributed in the plant body 1. The pipeline transportation system also includes an ammonia water pipeline 28 and a defoaming agent pipeline 29. The ammonia water tank transports ammonia water to the fermentation tank through the ammonia water pipeline 28, and the defoaming agent tank transports defoaming agent to the fermentation tank and the secondary seed tank through the defoaming agent pipeline 29. The ammonia water pipeline 28 and the defoaming agent pipeline 29 are both arc-shaped and arranged between two adjacent layers of fermentation tank groups. The ammonia water tank is connected to all the fermentation tanks in the fermentation system through the ammonia water pipeline 28, and the defoaming agent tank is connected to all the secondary seed tanks and fermentation tanks in the fermentation system through the defoaming agent pipeline 29.

[0059] For example, Figure 8 As shown, in the fermentation system in the first quadrant, the outermost tank body 2 is a fermentation tank A, the middle tank body 2 is divided into two feeding tanks B and three secondary seed tanks C, and the innermost tank body 2 is divided into three primary seed tanks D and two ammonia water tanks F. In the fermentation system in the second quadrant, the outermost tank body 2 is a fermentation tank A, the middle tank body 2 is divided into two feeding tanks B and three secondary seed tanks C, and the innermost tank body 2 is divided into three primary seed tanks D and two defoaming agent tanks E. The two defoaming agent tanks are arranged adjacent to the two feeding tanks. The division of the tank body 2 in the fermentation system in the third quadrant is the same as that in the first quadrant, and the division of the tank body 2 in the fermentation system in the fourth quadrant is the same as that in the second quadrant. The defoaming agent tank of the fermentation system in the second quadrant is shared with the fermentation system in the third quadrant, and the ammonia water tank of the fermentation system in the third quadrant is shared with the fermentation system in the second quadrant. The ammonia water tank of the fermentation system in the first quadrant is shared by the fermentation system in the fourth quadrant, and the defoaming agent tank of the fermentation system in the fourth quadrant is shared by the fermentation system in the first quadrant.

[0060] In addition, a cyclone separator is installed at the waste gas outlet of each fermentation tank to remove gas and the carried materials to achieve gas-liquid separation. An arc-shaped waste liquid pipe and a waste gas pipe are set in the bottom floor of the plant body 1. The waste liquid pipe is connected to the liquid outlet of the cyclone separator corresponding to each fermentation tank, and the waste gas pipe is connected to the gas outlet of the cyclone separator corresponding to each fermentation tank.

[0061] The layout of the circulating water pipe 11, steam pipe 8, feed pipe 26 and material pipe is described in detail below. Figure 7-9As shown, the fermentation tank group is divided into three layers, the fermentation tank is located in the outermost layer, the feeding tank and the secondary seed tank are located in the middle layer, and the primary seed tank is located in the innermost layer. They are arranged in a counterclockwise direction as the first quadrant area, the second quadrant area, the third quadrant area and the fourth quadrant area, and an ammonia tank is also set in the innermost layer of the first quadrant area and the third quadrant area, and a defoaming agent tank is also set in the innermost layer of the second quadrant area and the fourth quadrant area.

[0062] The layout of the steam pipe 8 is as follows: Figure 7-9 As shown: a steam main pipe 9 is set on the second floor of the plant body 1. The steam main pipe 9 is located between the upper two quadrants and the lower two quadrants. One end of the steam main pipe 9 extends from the left side across the internal area of the plant body 1 and is connected to the steam pipes 8 in the first quadrant and the second quadrant. The steam in the steam main pipe 9 is Figure 8 The steam starts to be transported from the left side and is transported to the steam pipe 8 in each fermentation system through the steam distribution bag 10. Figure 8 As shown, the steam pipe 8 on the second floor of the plant body 1 is used to transport steam to the secondary seed tank. The steam pipe 8 on this floor is connected to the steam pipe 8 on the first floor of the plant body 1 through the first steam branch pipe, so that the steam pipe 8 on the first floor of the plant body 1 can transport steam to the fermentation tank and the feeding tank. Figure 7 As shown. On the third floor of the plant body 1, the steam pipe 8 in each fermentation system surrounds the primary seed tank and the adjacent ammonia tank or defoamer tank. The steam distribution package 10 on the second floor of the plant body 1 is connected to the steam pipe 8 on the third floor of the plant body 1 through the second steam branch pipe. Steam is transported to the steam pipe 8 on the third floor of the plant body 1 through the steam distribution package 10. The steam pipe 8 on the third floor transports steam to the primary seed tank and the corresponding defoamer tank respectively, as shown. Figure 9 shown.

[0063] The layout of the circulating water pipe 11 is as follows Figure 10-12 As shown: the circulating water pipeline 11 includes a circulating water inlet pipeline 111 and a circulating water outlet pipeline 112. The circulating water inlet pipeline 111 and the circulating water outlet pipeline 112 are arranged in parallel on the first floor of the plant body 1 and surround the outside of the fermentation tank, as shown in FIG. Figure 10 As shown, due to the arrangement in an up-down manner, the circulating water inlet pipe 111 blocks the circulating water outlet pipe 112. Figure 10 The circulating water inlet pipe 111 and the circulating water outlet pipe 112 are both composed of multiple sections of water pipes with different diameters, and the diameters of the multiple sections of water pipes gradually decrease as they move away from the main water inlet and the main water outlet. Figure 10What is shown is the lower half area (the second quadrant area and the third quadrant area) of the top view of the plant body 1, including the second quadrant area and the third quadrant area, and the total water inlet and the total water outlet are arranged between the second quadrant area and the third quadrant area. For the upper half area (i.e. the first quadrant area and the fourth quadrant area) of the top view of the plant body 1, the circulating water pipes 11 are arranged in a symmetrical distribution, and the total water inlet and the total water outlet are arranged between the first quadrant area and the fourth quadrant area.

[0064] A plurality of first water inlet branches 12 are provided on the circulating water inlet pipe 111, and each first water inlet branch 12 is connected to a second water inlet branch 13 extending into the second floor of the plant body 1, and the second water inlet branch 13 is used to transport circulating water to the fermentation tank. The first water inlet branch 12 near the feeding tank is also connected to the third water inlet branch 14 extending into the second floor of the plant body 1 for inputting circulating water into the feeding tank. The first water inlet branch 12 near the secondary seed tank is connected to the fourth water inlet branch 15 extending into the second floor of the plant body 1 for transporting circulating water to the secondary seed tank. At the same time, the fourth water inlet branch 15 is connected to the fifth water inlet branch 16 extending into the third floor of the plant body 1 for transporting circulating water to the corresponding primary seed tank. Similarly, multiple first water outlet branch pipes 17 are set on the circulating water outlet pipe, and each first water outlet branch pipe 17 is connected to a second water outlet branch pipe 18 extending into the second floor of the factory building 1. The second water outlet branch pipe 18 is used to discharge the circulating water from the fermentation tank.
