Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of microorganism, especially to a kind of bacteria propagation device for viscose industry waste gas treatment. BACKGROUND
[0002] Viscose fiber production process will produce waste gas containing carbon disulfide (CS2), hydrogen sulfide (H2S) and the like, these waste gases are toxic, harmful to the environment and human body. By screening natural strains and domestication culture, a high-efficiency sulfur dioxide treatment bacterial population can be formed, and the organic pollutants in the waste gas can be degraded into harmless substances such as carbon dioxide and water by the metabolic action of microorganisms. The utility is more environmentally friendly. In order to propagate the bacteria for subsequent continuous participation in the work of viscose industry waste gas treatment, a fermenter is used for propagation operation.
[0003] Although the existing fermenter can propagate the bacteria, the fermenter uses mechanical stirring to uniformly stir the bacterial population. The shear force generated by the stirring rod during stirring may damage the desulfurization bacterial population, especially the fragile bacterial cell bodies, affecting their growth and metabolic activity, and thus reducing the subsequent desulfurization effect of the bacteria. UTILITY MODEL CONTENT

[0007] Preferably, a plurality of valve bodies are connected with the fermenter.
[0008] Preferably, a thermometer and a pH meter are installed on the fermenter.
[0009] Preferably, a feed valve and a discharge valve are connected with one end and the other end of the fermenter.
[0010] Preferably, a plurality of bases are connected with the fermenter.
[0011] Preferably, a window is formed in the fermenter.
[0012] Preferably, the plurality of valve bodies are equidistantly distributed two by two.
[0013] The beneficial effects of the present application are:
[0014] 1. By setting the fermentation tank, air pump, first pipe body, annular pipe body, second pipe body and one-way valve, the air in the fermentation tank is continuously extracted by the air pump through the first pipe body, and the bacteria liquid in the fermentation tank is continuously injected through the multiple second pipe bodies, so that the aerobic bacteria can fully absorb oxygen, and the vibration of the air to the bacteria liquid can also be used for stirring operation. This stirring method does not have a mechanical stirring rod, completely relies on the action of gas, and almost does not produce shear force, which can effectively avoid the damage of shear force to the bacteria, ensure the growth and metabolic activity of the bacteria, and further ensure the subsequent desulfurization effect of the bacteria.
[0015] 2. By setting the cooperation between the fermentation tank and the valve body, the multiple valve bodies installed at the fermentation tank can be used to conveniently discharge and sample the bacteria liquid at different positions in the fermentation tank, which can conveniently and comprehensively check the bacteria liquid to a certain extent, which is helpful to more accurately evaluate the progress of the fermentation process, including the growth stage of the bacteria, metabolic activity and whether there is pollution problem, so as to ensure that the bacteria can be stably expanded.

[0022] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments.
[0023] Embodiment 1, refer to Figures 1 to 5 The utility model provides a kind of strain propagation device for viscose industry waste gas treatment, including fermenter 1, gas pump 2 is installed at fermenter 1, gas pump 2 is the power source of entire gas path system, it is stable and reliable, can provide sustained and adjustable air flow, the model of gas pump 2 is selected according to actual work demand. One end of gas pump 2 is connected with first pipe body 3, first pipe body 3 is connected in fermenter 1, the main role of this first pipe body 3 is to extract gas in fermenter 1, form a gas circulation passage, one end of gas pump 2 is connected in fermenter 1, one end of gas pump 2 is connected with annular pipe body 4, annular pipe body 4 is connected with fermenter 1 inner wall, annular pipe body 4 is connected with fermenter 1 inner wall closely, its special annular structure design can make gas evenly distribute in fermenter 1, a plurality of second pipe bodies 5 are connected at annular pipe body 4, a plurality of second pipe bodies 5 are connected with one-way valve 6, a plurality of second pipe bodies 5 connected at annular pipe body 4 then is after the air of pressurization by gas pump 2 re- inject into the bacteria liquid in fermenter 1. The layout of a plurality of second pipe bodies 5 is carefully designed, ensure that bacteria liquid in different positions can receive air. Moreover, one-way valve 6 connected at each second pipe body 5 can effectively control the flow direction of gas, only allow air to flow from annular pipe body 4 to bacteria liquid, prevent bacteria liquid from flowing into gas path system, ensure the normal operation and health safety of gas path system, and with the aid of gas type stirring, bacteria damage can also be avoided, ensure the quality of bacteria.
[0024] In this embodiment, the fermentation tank 1 is connected with multiple valve bodies 7, which are designed to provide great convenience for sampling and discharging operations during the strain expansion process. Through the valve bodies 7 at different positions, the discharge and sampling work of the bacterial liquid in the fermentation tank 1 at different positions can be conveniently carried out. During the strain expansion process, regular sampling from different positions can to a certain extent comprehensively check the bacterial liquid, so as to accurately understand the overall situation of the bacterial liquid in the fermentation tank 1. For example, the concentration of microorganisms, the content of nutrients, the concentration of metabolic products and other key indicators in the bacterial liquid can be detected, and the fermentation conditions can be adjusted in time according to the detection results, such as adding nutrients, adjusting the aeration amount, etc., to ensure that the strain expansion process is always in the best state. The thermometer 9 and the PH meter 10 installed at the fermentation tank 1 constitute a relatively perfect monitoring system together with the valve body 7. The thermometer 9 can monitor the temperature of the bacterial liquid in the fermentation tank 1 in real time, which is very important for controlling the growth environment of the strain, because different strains have specific requirements for temperature at different growth stages. The PH meter 10 is used to detect the pH value of the bacterial liquid. The growth and metabolism of microorganisms will affect the pH value of the bacterial liquid, and the appropriate pH range is crucial for the activity and metabolic function of the strain. Through regular sampling combined with valve body 7 and real-time monitoring data of thermometer 9 and PH meter 10, the physical, chemical and biological properties of the bacterial liquid can be comprehensively mastered, providing accurate data support for optimizing the strain expansion process. The fermentation tank 1 is connected with feed valve 11 and discharge valve 12 at one end and the other end, and is connected with multiple bases 13. The fermentation tank 1 is provided with a window 8, which provides an observation window for the operator to directly observe the situation in the fermentation tank 1. The window 8 is made of pressure-resistant and transparent materials such as tempered glass, which can clearly show the liquid level, color, bubble generation of the bacterial liquid in the fermentation tank 1. Through the observation of the window 8, the operator can real-time understand the progress of the fermentation process without opening the fermentation tank 1, such as the growth state of the strain, whether there is excessive foam and other abnormal phenomena, so as to take corresponding measures for adjustment and treatment in time. The multiple valve bodies 7 are distributed equidistantly.
[0025] The working principle of this embodiment is as follows: when in use, the bacterial liquid is injected into the fermentation tank 1 through the feed valve 11 with the help of external conveying equipment. After injection, the uppermost valve body 7 is used to inject oxygen, discharge oxygen or put some objects to ensure the growth of the strain. At the same time, the air pump 2 can be connected to the external power supply to run. The air pump 2 can transport the oxygen in the fermentation tank 1 through the annular pipe body 4, the second pipe body 5 and the one-way valve 6 with the help of the first pipe body 3, and inject it into the bacterial liquid in the fermentation tank 1 for circulation. In this way, not only can the oxygen be fully contacted with the bacterial liquid, but also the bacterial liquid can be stirred to ensure the stability of the bacterial liquid growth. Subsequently, multiple valve bodies 7 can be used to sample and inspect the bacterial liquid at different heights.
[0026] The above merely describes a preferred embodiment of the present application, but the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
