  1 and 2, the present invention is used for culturing algal microorganisms (such as cyanobacteria), and includes a photosynthetic reaction unit 1, a pressurized liquid export unit 2, a jet exhaust oxygen device 4, a control zone 5, a communication device. 6 is a photosynthetic reaction system for algal microorganisms.

  The photosynthetic reaction unit 1 includes a plurality of straight pipes 10 and a plurality of bay-shaped pipes 11. The straight pipes 10 and the bay-shaped pipes 11 are connected in series and spirals inclined in parallel. A transparent pipe made of a transparent material such as glass, which forms a transparent pipe path of the formula, and the other auxiliary opening 12 is at the apex of the transparent pipe path. The pressurized liquid export unit 2 is a pressurized liquid export pump in which the inlet side penetrates the outlet side of the transparent pipe path. The jet exhaust oxygen device 4 is a hollow pipe including an exhaust oxygen cylinder 40 made of stainless steel and a liquid collection cylinder 41 made of a transparent material such as glass or acrylic. A liquid inlet 401, an upper exhaust outlet 402, and a hollow pipe wall 403 are installed in the upper stage of the exhaust oxygen cylinder 40, and the pipe 20 penetrates to the outlet side of the pressurized liquid unit 2 through the liquid inlet 401. The upper end exhaust port 402 is located at the upper end of the exhaust oxygen cylinder 40, and the hollow pipe wall 403 extends downward from the upper end exhaust port 402 and faces the inside of the ingress liquid port 401. . A neck portion 404 and an exhaust port 405 at a side end located below the neck portion 404 are installed in the middle stage of the exhaust oxygen cylinder 40. The jet exhaust oxygen device 4 includes an exhaust pipe 42, and the exhaust pipe 42 is connected to the exhaust oxygen cylinder 40, and the upper end of the exhaust pipe 42 passes through the hollow pipe wall 403, An enlarged portion 421 is formed at the lower end, and the enlarged portion 421 is positioned inside the exhaust port 405 at the side end. The adjustment zone 5 includes an expansion pipe 52 and is made of a transparent material such as glass. One end of the control zone 5 communicates with the photosynthetic reaction system 1, and the other end communicates with the liquid collecting cylinder 41 of the jet exhaust oxygen device 4 via the communicating device 6. The continuous device 6 is connected to the bottom of the liquid collecting cylinder 41. It communicates with the bottom of the expansion pipe 52 in the adjustment zone 5. The communication device 6 has a cleaning plug kit 60. The inlet of the transparent pipe communicates with the control zone 5 downward.

  The algal microbial photosynthetic reaction system of the present invention includes a collection stopper kit 7. The collection stopper kit 7 is connected between the outlet of the transparent pipe and the inlet of the pressurized liquid export unit 2 and flows by sucking algal microorganisms and broth in the transparent pipe.

  When using the algal microbial photosynthetic reaction system of the present invention, the algae species of the algal microorganisms and the broth of the cultured algae microorganisms are injected into the transparent pipe through the auxiliary opening 12 of the transparent pipe, It flows in a transparent pipe and at the same time performs photosynthesis to produce oxygen, and the brother flows toward the pressurized liquid export unit 2. The pressurized liquid export unit 2 is opened and the brother is forced to flow from the transparent pipe to the jet exhaust oxygen device 4. When the brother is injected into the exhaust oxygen cylinder 40 through the liquid inlet 401, the brother is first caught in the exhaust oxygen cylinder 40 of the jet exhaust oxygen device 4 to form a fountain, and the exhaust at the upper end. Oxygen is discharged from the mouth 402. Subsequently, when the brother is dropped and collected on the neck portion 404, it is caught by the extended portion 421 of the exhaust pipe 42 to form a fountain shape, and oxygen is discharged from the exhaust port 405 at the side end. Finally, the broth falls and collects in the liquid collecting cylinder 41 and discharges oxygen from the upper end of the exhaust pipe 42. In this way, most of the oxygen can be discharged, and the photosynthesis ability of the brother can be enhanced. When the broth passes through the exhaust oxygen cylinder 40, a liquid in which oxygen is saturated is generated, so that photosynthesis cannot be continued. Therefore, the exhaust oxygen cylinder 40 is made of a material that does not transmit light, such as stainless steel. It is made with. Further, when the brother is collected in the liquid collecting cylinder 41, most of the oxygen has already been exhausted and photosynthesis can be performed continuously. Therefore, the liquid collecting cylinder 41 is made of a transparent material such as glass. Made of. When the broth flows through the communication device 6 to the control zone 5, the washing plug kit 60 can be temporarily opened to remove relatively heavy sediment, and the broth can be sampled and measured. In addition, since the diameter of the cylinder of the expansion pipe 52 is very large compared to the diameter of the communication device 6, the flow speed of the broth is considerably slow here, and the algal microorganisms are physiologically controlled in the control section 5 over a sufficient time. Then, the physiological injury caused by the action of the pressurized liquid export unit 2 and the jet exhaust oxygen device 4 is removed. When the pressure of the pressurized liquid export unit 2 applies a load to the transparent pipe, the brother is absorbed from the expansion pipe 52 into the transparent pipe and further performs photosynthesis. In addition to this, the height of the liquid level of the broth collected in the liquid collecting cylinder 41 is increased to the uppermost layer of the transparent pipe of the photosynthetic reaction unit 1, and the liquid level of the liquid collecting cylinder 41 and the level of the transparent pipe liquid level are increased. By utilizing the difference between the two, the broth is automatically poured into the transparent pipe from the control section 5 by the action of gravity, the photosynthesis action is performed again, and further flows toward the pressurized liquid export unit 2. At the same time, the assistant opening 12 is opened to maintain a constant pressure, and the liquid level of the liquid collecting cylinder 41 and the control zone 5 is made to coincide using the Pascal principle. Thus, the algal microorganism broth in the algal microorganism photosynthetic reaction system of the present invention, when the algal microorganism is gradually propagated by circulating culture many times, and the content of the algae in the broth has reached a level that can be collected, The collection stopper kit 7 is opened and collected, and at the same time the washing stopper kit 60 is opened and collected. At the same time, the collection speed is increased. Therefore, a preferable quality of algal microorganisms can be collected. Also, if the pressure in the transparent pipe increases and the broth level of the cultured algal microorganisms in the control zone 5 rises, the pressure level of the broth is adjusted by adjusting the pressure of the pressurized liquid export unit 2 to export. And the pressure in the transparent pipe can be kept in the most suitable state for the growth of algal microorganisms.

  In addition, the algal microbial photosynthetic reaction system of the present invention further includes a heating unit 8 and a shower unit 9, and the heating unit 8 includes a plurality of heating pipes 80, an inlet pipe 81, and an outlet pipe 82. The heating pipe 80 connects the outlet of the transparent pipe and the inlet of the pressurized liquid export unit 2 through an inlet pipe 81 and an outlet pipe 82, respectively. The heating unit 8 can heat the water in the heating unit 8 manually or automatically, and transmits the heat of the water to the heating pipe 80 to adjust the temperature of the brother. The shower unit 9 is on the upper side of the photosynthetic reaction unit 1 and, according to the working environment, showers are performed at a predetermined time by a manual or automatic sensing method, and the brother in the transparent pipe is The temperature can be lowered.

  As shown in FIG. 3, the control zone 5 of the algal microbial photosynthetic reaction system of the present embodiment may have a straight pipe 53, and one end of the control zone 5 is the same as the photosynthesis reaction unit 1. The other is communicated with the liquid collecting cylinder 41 by the communication device 6, and the algae similarly flows into the photosynthetic reaction unit 1 through the control section 5 of the straight pipe 53 and is circulated and cultured. Since the purpose of the control group 5 is to physiologically control algae in the control group 5, for the algal microorganisms that take a relatively short time for physiological control, the control group 5 of the straight pipe 53 is used, and the transparent pipe is used as the transparent pipe. For algal microorganisms that circulate culture by flowing quickly and take a relatively long time for physiological regulation, the regulation zone 5 of the expansion pipe 52 shown in FIG. 1 must be used. By slowing down the speed, sufficient time for physiological regulation required by algal microorganisms is taken.

  Another embodiment shown in FIG. 4 is intended to improve mainly in an environment with a high oxygen production amount. As the amount of oxygen produced increases, the amount of oxygen that must be discharged naturally increases. Therefore, in this embodiment, the length of the hollow pipe wall 403 is made short above the liquid inlet 401. When the broth is injected into the exhaust oxygen cylinder 40 through the liquid inlet 401 of the jet exhaust oxygen device 4 and further caught by the exhaust pipe 42, it is partially before the fountain-like water falls due to the catch. Oxygen can be discharged, and the amount of discharged oxygen can be greatly increased. However, when an impact is applied to the exhaust port 402 at the upper end in the above-described broth, the output is slightly reduced because the brozzer is partially hooked from the exhaust port 402 at the upper end.

Referring to FIGS. 1 to 5, the method of photosynthesis reaction of an algal microorganism of the present invention includes the following steps.
(1) The process of providing a transparent pipe, a pressurized liquid export unit 2, a jet exhaust oxygen device 4, and a control zone 5.

(2) Injecting broth and algae into the transparent pipe, the broth flows in the transparent pipe, performs photosynthesis, generates oxygen, and the broth flows toward the pressurized liquid export unit 2 Journey. The transparent pipe is a spiral transparent pipe, and therefore the broth flows in order from the top to the bottom in a transparent manner, and the algal microorganisms absorb light and perform photosynthesis. Breed quickly.
(3) Opening the pressurized liquid export unit 2, forcing the broth toward the jet exhaust oxygen device 4 and hooking the broser to the jet exhaust oxygen device 4 to form a fountain and discharging oxygen . The brother gives an impact into the discharge oxygen cylinder 40 of the jet discharge oxygen device 4 to form fountain-like water and discharge oxygen from the upper exhaust port 402. Subsequently, when the brother falls to the neck portion 404 and is collected, an impact is given to the extended portion 402 of the exhaust pipe 42 to form a fountain shape, and oxygen is discharged from the discharge port 405. Finally, the broth falls and collects in the liquid collecting cylinder 41 and naturally discharges oxygen from the upper end of the exhaust pipe 42. In this way, most of the oxygen in the broth can be discharged and the algal microorganisms can again carry out photosynthesis.
(4) The process of collecting the broth in the jet exhaust oxygen device 4 and the control zone 5, and the broth flows in the transparent pipe and performs photosynthesis again. The broth is collected in the liquid collecting cylinder 41 and poured into the control zone 5 through the communication device 6. Subsequently, due to the action of the pressurized liquid export unit 2, the broth is absorbed up to the transparent pipe in the control zone 5, and the photosynthetic reaction is performed again. Alternatively, the liquid level of the broth collected by the liquid collecting cylinder 41 is higher than the uppermost layer of the transparent pipe of the photosynthetic reaction unit 1, and the algal broth is automatically removed by gravity action using the difference in height. Pour from the control zone 5 into a transparent pipe.
Further, the step (2) further provides a heating unit 8, and the brother flows through the heating unit 8 and further toward the pressurized liquid export unit 2 to adjust the temperature of the brother.
Further, the step (2) further provides a shower unit 9, which showers on the transparent pipe and adjusts the temperature of the brother in the transparent pipe to be low as required in the working environment. .
Further, the step (4) provides a collection stopper kit 7, and after the brother flows through the transparent pipe, the collection stopper kit 7 sucks the brother.
