In the process of algae cultivation, when the culture solution flows into the connecting pipe body 34, since the connecting pipe body 34 is an expansion tube, the flow velocity of the culture solution can be greatly slowed down here, so that the culture solution flows into the connecting pipe body 34 from the expansion pipe. The light-transmitting pipeline takes a long time, so that the algae microorganisms in the culture solution have enough time to perform physiological adjustment in the connecting pipe body 34, so as to eliminate the effects of the pressurized infusion unit 32 and the jet oxygen exhaust unit 33 The physiological damage caused can enter the light-transmitting pipeline in the best physiological state, and therefore the best quality algae, such as cyanobacteria, haematococcus or oil algae, can be harvested.

Please refer to Fig. 5, in the present embodiment, the connecting pipe body 34 is a straight pipe, one end of which is also communicated with the photosynthetic reaction unit 31, and the other end is also communicated with the liquid collection tube 332 through a communication pipe member 39, and The culture solution also flows into the light-transmitting tube part through the connecting tube body 34 which is a straight tube for circulating culture.

From the above, due to one of the technical effects of the connecting pipe body 34, it enables the algae microorganisms in the culture solution to have the purpose of physiological adjustment in the connecting pipe body, but for the algae microorganisms that take a short time for physiological adjustment, they can It is a straight pipe so that algae microorganisms can speed up the flow into the light-transmitting pipeline for cyclic culture, and for algae microorganisms that need to perform physiological adjustment for a long time, it is necessary to use the aforementioned connecting pipe body 34 that is an expansion pipe to slow down the growth of the culture medium. The flow rate in the connecting pipe body 34 allows the algae microorganisms to have enough time for physiological adjustment.

Please refer to Fig. 6 again. Different changes can be made in each algae photosynthetic reaction device 3 of the present invention. The liquid collecting cylinder 332 of the spray oxygen exhausting unit 33 faces the oxygen exhausting cylinder 331 and shortens the lower section upwards, and the connecting pipe body 34 can be a horizontal flow pipe to communicate with the liquid collecting cylinder 332 and the light-transmitting pipeline, so that the culture medium does not Need to carry out the function of physiological adjustment, and quickly flow into the light-transmitting pipeline.

Please refer to Fig. 7, and refer to Fig. 2 together; in this embodiment, the culture solution flowing from the oxygen exhaust cylinder 331 to the liquid collection cylinder 332 will stick to the liquid collection cylinder 332 because of some specific algae species (referring to Fig. 2), this is because the velocity slows down when the nutrient solution of algae is circulated here, and can flow in the photosynthetic reaction unit 31 from the connecting pipe body 34 after being pressurized, and this flow velocity slows down and is subjected to again. The effect of pressure makes specific algae species stick to the wall surface, that is to say, when the river flow slows down, sludge is deposited. Therefore, as shown in Figure 7, each algae photosynthetic reaction device 3 of the present invention can further include a Regulating cylinder 42 and a connecting pipe 43, the bottom of the regulating cylinder 42 communicates with the outlet end of the light-transmitting pipeline, which can be connected to the outlet end of the above-mentioned recovery valve assembly 36, and the connecting pipe 43 communicates with the top of the regulating cylinder 42 and The inlet port of the pressurized infusion unit 32 .

From the above, when the culture solution flows into the regulating cylinder 42 and the liquid level rises to the top, the pressurized infusion unit 32 can be opened to force the culture solution into the jet oxygen exhaust unit 33 by its suction force, and the collected The liquid cylinder 332 is further shortened upwards. Therefore, although the speed of the culture fluid flowing into the regulating cylinder 42 slows down, it is less likely to be deposited on the wall by the suction force of the pressurized infusion unit 32 , and after flowing into the liquid collection cylinder 332 Can quickly flow into the photosynthetic reaction unit 31 again, and can increase the rapid cycle production. However, the disadvantage of this embodiment is that some components (such as adjusting cylinder 42, connecting pipe 43 or/and joints, etc.) and space must be added, so the manufacturing cost will increase. The situation of algae depositing sticky walls (this deposit means not reproducing), can increase the purpose of rapid production, thereby increasing production capacity, that is, it can break through the defect of manufacturing cost.

In addition, as shown in Figure 8, in order to increase the mass production of algae, the volume of the light-transmitting pipeline can be increased. When the length d of the light-transmitting pipeline is 20-30m, the volume increase will affect the drainage. The exhaust effect of the oxygen liquid, so in order to increase the exhaust effect of the culture solution in the light-transmitting pipeline, so as to avoid the deterioration of the exhaust effect, the algae photosynthetic reaction device 3 of the present invention can further include at least one exhaust unit 44, It includes an exhaust liquid collection cylinder 441, a first through pipe 442 and a second through pipe 443, the inlet end of the first through pipe 442 is connected to the middle section of the light-transmitting pipeline and the outlet end is connected to the exhaust liquid collection The top of the cylinder 441, the inlet end of the second through pipe 443 is connected to the bottom of the exhaust liquid collection cylinder 441 and the outlet end is connected to the middle section of the light-transmitting pipeline, and the top end of the exhaust liquid collection cylinder 441 is open . Wherein, the exhaust liquid collection cylinder 441 can be designed to be the same as the above-mentioned oxygen exhaust cylinder 331 and liquid collection cylinder 332 .

From the above, in order to make the culture solution flowing into the light-transmitting pipeline flow into the exhaust liquid collection tube 441 through the first through pipe 442, and further discharge oxygen again here, the culture solution can be released by the second The through pipe 443 flows back into the light-transmitting pipeline. However, the number of exhaust units 44 can be set according to actual needs, that is, with the volume change of the light-transmitting pipeline and the needs of exhaust, etc., there can be two, three or four or more different quantities, which can be used. As a second, third, fourth, etc. exhaust design.

Through the above description, the present invention combines the algae production equipment 200 with the carbon dioxide generation system 100, so that the emitted carbon dioxide can be collected and reused to achieve the purpose of saving discharge, and the produced algae (such as cyanobacteria, red balls Algae, etc.) have economic value and can be made into edible products, etc., or the produced algae (such as oil algae) can be extracted into quality oil products, etc. In addition, each algae photosynthetic reaction device 3 is composed of a light-transmitting pipeline, a pressurized infusion unit 32, a jet oxygen exhaust unit 33 and a connecting pipe body 34, so that the culture solution injected into it can be formed in vertical three-dimensional rows.
