Detailed implementation manners

[0022] To enable those skilled in the art in the technical field to which the present application pertains to more clearly understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present application.

[0023] Please refer to Figure 1 As shown, the embodiment of the present application provides a biological fermentation nitrogen source addition system, including a main pipe 2, a nitrogen source 1, branch pipes 3, metering pumps 4, a first valve 5, a second valve 6, a fermentation device 7, a connecting pipe 8, a bypass pipe 9 and a bypass valve 10, wherein:

[0024] One end of the main pipe 2 is connected to the nitrogen source 1;

[0025] There are at least two branch pipes 3, and at least two branch pipes 3 are all communicated with the main pipe 2. The ends of the branch pipes 3 are connected to the fermentation device 7. On each branch pipe 3, a metering pump 4, a first valve 5 and a second valve 6 are sequentially arranged from the main pipe 2 to the fermentation device 7;

[0026] The connecting pipe 8 is arranged between two of the branch pipes 3 at the two ends of at least two branch pipes 3;

[0027] The bypass pipe 9 is connected to the connecting pipe 8, and each branch pipe 3 is connected to one bypass pipe 9. The connection point of the bypass pipe 9 and the branch pipe 3 is located between the first valve 5 and the second valve 6;

[0028] The bypass valve 10 is arranged on the bypass pipe 9.

[0029] For the biological fermentation nitrogen source addition system provided in this embodiment, when the metering pump 4 of one of the branch pipes 3 is damaged or needs to be overhauled, the first valve 5 on the current branch pipe 3 can be closed, and the bypass valve 10 on the bypass pipe 9 connected to the current branch pipe 3 can be opened. Nitrogen flows into the current fermentation device 7 from the bypass pipe 9 and the second valve 6 through the metering pump 4 of the adjacent branch pipe 3, so that the fermentation device 7 on the branch pipe 3 corresponding to the damaged metering pump 4 can be supplemented with nitrogen, thereby timely and stably providing the nitrogen source 1 for the fermentation device 7, avoiding affecting the reproduction and metabolism of bacteria due to lack of metabolic substrates, and at the same time avoiding affecting the pH environment of the healthy metabolism of the bacterial strain.

[0030] In some alternative embodiments, a pulsation damper 13 is further provided on the branch pipe 3, and the pulsation damper 13 is located between the metering pump 4 and the first valve 5. The pulsation damper 13, also known as a flow damper, is usually used in hydraulic or pneumatic systems. Its function is to eliminate pressure pulsations (fluctuations) in high-pressure oil or gas pipelines and stabilize the pipeline pressure within a certain range. The nitrogen coming from the metering pump 4 enters the fermentation device 7 through the corresponding pipeline after being pressure-stabilized by the pulsation damper 13, improving the stability and reliability of the device.

[0031] In some alternative embodiments, an inlet valve 11 is provided on each branch pipe 3, and the inlet valve 11 is located between the main pipe 2 and the metering pump 4. By providing the inlet valve 11 between the main pipe 2 and the metering pump 4, when the metering pump 4 needs to be maintained or when this branch pipe 3 needs to stop supplying nitrogen to the fermentation device 7, the inlet valve 11 can be closed. The other valves on the branch pipe 3 do not need to be adjusted. Next time it is used, no further adjustment is required, saving operation time.

[0032] In some alternative embodiments, an outlet valve 12 is provided on each branch pipe 3, and the outlet valve 12 is located between the fermentation device 7 and the second valve 6. By providing the outlet valve 12 between the fermentation device 7 and the second valve 6, when other components on the branch pipe 3 need to be repaired, the outlet valve 12 can be closed, facilitating the operation.

[0033] In some alternative embodiments, a self-operated regulating valve 14 is further provided on the branch pipe 3, and the self-operated regulating valve 14 is located between the second valve 6 and the outlet valve 12. The self-operated regulating valve 14, also known as a self-operated control valve, is a regulating valve that relies on the pressure and temperature of the medium flowing through the valve itself as the energy source to drive the valve to work automatically without the need for an external power supply and secondary instrument. The self-operated regulating valve 14 here is used to stabilize the flow rate. After the temperature and flow rate are adjusted by the self-regulating valve, it enters the fermentation device 7, which can improve the stability and reliability of the device.

[0034] In some alternative embodiments, both the inlet valve 11 and the outlet valve 12 are ball valves. Ball valves are mainly used in pipelines to cut off, distribute, and change the flow direction of the medium. It only needs a 90-degree rotation operation and a very small turning torque to close tightly. Therefore, using ball valves for the inlet valve 11 and the outlet valve 12 can facilitate the quick on-off control of the pipeline.

[0035] In some alternative embodiments, the biological fermentation nitrogen source addition system further includes a pH sensor (not shown in the figure), and the pH sensor is disposed in the fermentation device 7. By providing a pH sensor in the fermentation device 7, the pH value of the fermentation device 7 can be monitored in real time, so that the nitrogen supplementation amount can be controlled by the metering pump 4 to adjust the pH of the fermentation device 7 to the required pH value.

[0036] In some alternative embodiments, both the first valve 5 and the second valve 6 are ball valves. By using ball valves for both the first valve 5 and the second valve 6, it is convenient to control the rapid on / off of the pipeline.

[0037] The working principle of the biological fermentation nitrogen source addition system proposed by the present utility model is as follows: When the metering pump 4 of one of the branch pipes 3 is damaged or needs to be overhauled, the first valve 5 on the current branch pipe 3 can be closed, and the bypass valve 10 on the bypass pipe 9 connected to the current branch pipe 3 can be opened (other bypass valves 10 are closed). The nitrogen flows from the bypass pipe 9 and the second valve 6 into the current fermentation device 7 through the metering pump 4 of the adjacent branch pipe 3, so that the fermentation device 7 on the branch pipe 3 corresponding to the damaged metering pump 4 can be supplemented with nitrogen, thereby timely and stably providing the nitrogen source 1 for the fermentation device 7, avoiding the influence on the reproduction and metabolism of bacteria due to the lack of metabolic substrates, and at the same time avoiding the influence on the pH environment for the healthy metabolism of the bacterial strain.
