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, such as Figure 1 As shown, the letter H represents the seed tank, the letter A represents the fermentation tank, and the letter B represents the feed tank. The following problems exist: First, it occupies a large area and can accommodate only a few fermentation tanks per unit area.

[0004] Second, the length of the pipeline between the feed tank / seed tank and the fermentation tank is high. For example, if you want to transport the liquid in the seed tank and feed 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 the 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 the involved transport pipelines need to be disinfected, resulting in excessive disinfection pressure and increased fermentation costs.

[0005] Third, the fermentation tanks are arranged in the east-west direction of the workshop. When the staff needs 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 and lead to fermentation failure.

[0006] Therefore, a new microbial fermentation plant with a circular distribution of tank bodies is urgently needed to solve the above-mentioned technical problems. Summary of the invention

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

In addition, the terms "first", "second", etc. are used to define components, only for the convenience of distinguishing the above components, and unless otherwise stated, the above terms have no special meanings and cannot be understood as indicating or implying relative importance.

[0025] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "setting", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] The present invention relates to the field of microbial fermentation technology, and in particular to a microbial fermentation plant with a circumferentially distributed tank body. The purpose is to solve the following problems: first, the existing microbial fermentation workshop occupies a large area, and the fermentation tanks that can be accommodated per unit area are few; second, the distance between the control room and the fermentation tank is long, which is time-consuming and laborious for personnel to conduct inspections and other operations, and it is easy to bring risks of contamination to other tank bodies; third, the length of the pipeline between the feed tank / seed tank and the fermentation tank is long, which not only causes the conveyed material to remain in the pipeline and cause 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 the involved conveying pipelines need to be disinfected, 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, comprising a plant body, a tank body and a studio. The plant body is a cylindrical structure, and the central area within the plant body forms an elevator shaft and a multi-floor studio. An elevator is installed in the elevator shaft, and 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 within the plant body is surrounded by multiple layers of fermentation tank groups that are distributed at intervals. Each layer of the fermentation tank group includes a plurality of 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 operations such as 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.

[0027] The following is a detailed description of the microbial fermentation plant with circumferentially distributed tanks provided in an embodiment of the present invention in conjunction with the accompanying drawings.

[0028] See also Figure 2-6 The present invention provides a microbial fermentation plant with a circumferentially distributed tank body, 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 a multi-layer and spaced fermentation tank group. Each layer of the 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.

[0029] Specifically, multiple workshops can be designed on each floor of the studio. Each workshop can be one or more of the exhaust gas treatment area, tool room, strain room, laboratory, control room 4, etc. One or two workshops of the same type can also be set. 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 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, the same floor as the control room.

[0030] 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 arranged in the outermost layer, which is convenient for radiating the heat generated by the fermentation to the outside.

[0031] In one embodiment, a plurality of floors are arranged in the plant body 1, and the top of each tank body 2 is located on the same floor in the plant body 1. The highest floor studio 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, and the tank 2 can be intuitively monitored and controlled. The studio on the highest floor also includes a closed viewing passage 3, which is a ring structure surrounding the outside of the elevator shaft 5 for viewing the distribution of each tank 2 in the plant body 1.

[0032] Specifically, the side of the viewing passage 3 facing the inside of the plant body 1 is made of glass, which is convenient for viewing. At the same time, the viewing passage 3 is designed to be annular, that is, it surrounds a circle, for visitors to visit. When visiting, they can directly observe the arrangement of each tank body 2, with a wider field of vision, and do not touch the tank body 2, preventing the microorganisms carried by outsiders from contaminating the fermentation tank. And this floor is lower than the floor where the viewing passage 3 is located, which is convenient for observing the distribution of the tank body 2 through the viewing passage 3.

[0033] For example, Figure 3 As shown, there are four floors in the plant body 1 for installing the tank body 2. The heights of the tank bodies 2 are different. The highest tank body 2 is installed from the first floor to the fourth floor, while the lower tank body 2 can be installed from the second floor to the fourth floor or from the third floor to the fourth floor according to the height, so as to ensure that the top of the tank body 2 is on the fourth floor. The top floor of the tank body 2 is provided with a pressure detector and an opening to facilitate the staff to monitor and operate on the top of the tank body 2. The studio has six floors, and the control room 4 and the visit passage 3 are set on the top floor.

[0034] In one embodiment, a first lighting and ventilation skylight 6 is provided in the central area of ​​the roof of the factory building body, 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 body 1.

[0035] In one embodiment, see Figure 4-6 The tank bodies 2 in the plant body 1 are combined to form a plurality of independent fermentation systems, and each fermentation system includes a portion 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, and can carry out fermentation of the same microorganism or fermentation of different microorganisms. It should be noted that the present 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.

[0036] Exemplarily, the plant body is divided into four quadrant areas according to the quadrant division principle, and 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 a fermentation system is set in each quadrant area.

[0037] In the above embodiments, each fermentation system can ferment different or the same microorganisms. Since the fermentation systems are independent of each other, the problem of mutual contamination can be avoided.

[0038] In one embodiment, see Figure 4-6 The tank body 2 in the fermentation system is divided into a feed 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 feed tank B and the seed tank. Each fermentation system is equipped with a pipeline transportation system, which includes a circulating water pipeline 11, a steam pipeline 8, a feed pipeline 26 and a material pipeline. The circulating water pipeline 11, the steam pipeline 8, the feed pipeline 26 and the material pipeline are all in an arc shape and surround the tank body 2 in the corresponding fermentation system. The steam pipeline 8 is respectively connected to the feed tank, the seed tank and the fermentation tank for introducing steam. The feed tank is connected to all the fermentation tanks in the corresponding fermentation system through the feed 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 the fermentation tanks, the seed tanks and the feed tanks.

[0039] 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 a 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. 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.

[0040] In one embodiment, the tank body 2 in one part of the fermentation system is also divided into an ammonia water tank, and the tank body 2 in another part of the fermentation system is also divided into a defoamer tank. The ammonia water tank and the defoamer tank are both located in the innermost fermentation tank group. The fermentation system with the ammonia water tank and the fermentation system with the defoamer tank are alternately distributed in the plant body 1. The pipeline transportation system also includes an ammonia water pipeline 28 and a defoamer pipeline 29. The ammonia water tank transports ammonia water to the fermentation tank through the ammonia water pipeline 28, and the defoamer tank transports defoamer to the fermentation tank and the secondary seed tank through the defoamer pipeline 29. The ammonia water pipeline 28 and the defoamer pipeline 29 are both arranged in an arc shape 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 defoamer tank is connected to all the secondary seed tanks and fermentation tanks in the fermentation system through the defoamer pipeline 29.

[0041] 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 tank body 2 in the middle layer is divided into two feed 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.

The division of the tank body 2 in the fermentation system in the third quadrant is the same as the division of the tank body 2 in the first quadrant, and the division of the tank body 2 in the fermentation system in the fourth quadrant is the same as the division of the tank body 2 in the second quadrant. The defoamer 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 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.

[0042] In addition, a cyclone separator is installed at the waste gas outlet of each fermentation tank to remove gas and carried materials to achieve gas-liquid separation. An arc-shaped waste liquid pipe and a waste gas pipe are arranged in the bottom layer 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.

One end of the steam main pipeline 9 extends from the left side across the internal area of ​​the plant body 1 and is connected to the steam pipelines 8 in the first quadrant and the second quadrant. The steam in the steam main pipeline 9 is Figure 8 The steam starts to be transported from the left side of the steam distribution bag 10 and is transported to the steam pipe 8 in each fermentation system.
