[0008] As a further improvement of this utility model, the air supply pipe passes through the conical cover and forms a sliding insertion fit with the bottom end of the conical cover.

[0009] As a further improvement of this utility model: the bottom end of the air supply pipe is connected to a flipping plate, and the middle part of the flipping plate has an air outlet that communicates with the air supply pipe.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example 1, referring to Figure 1-4 A photobioreactor includes a support plate 1, a reaction vessel 2 fixed to the upper end of the support plate 1, an L-shaped support plate 6 fixed to the upper end face of the support plate 1 and one side of the reaction vessel 2, a connecting ring 7 connected to one end of the horizontal section of the L-shaped support plate 6, a U-shaped rod 10 fixed to the upper end face of the connecting ring 7, a telescopic cylinder 11 fixed to the lower end face of the horizontal section of the U-shaped rod 10, a gas supply pipe 14 connected to the lower end of the telescopic cylinder 11, an annular light strip 17 fixed to the lower end face of the connecting ring 7, and the annular light strip 17 provides illumination conditions. A drain valve 16 is installed at the bottom end of the reaction vessel 2, and support legs 4 are fixed at the four corners of the lower end face of the support plate 1.

[0021] A solenoid valve 18 is installed on the top of the side wall of the air supply pipe 14. One end of the solenoid valve 18 is connected to a connecting hose 13. An air storage tank 8 is fixed on the upper surface of the support plate 1. One end of the connecting hose 13 is connected to the air outlet of the air storage tank 8. A limit hole 12 is opened on one side of the vertical section of the U-shaped rod 10. The connecting hose 13 passes through the limit hole 12.

[0022] A conical cover 9 is fixed to the lower end face of the connecting ring 7 and inside the ring light strip 17, and the bottom end of the conical cover 9 is set to an open state.

[0023] The air supply pipe 14 passes through the conical cover 9 and forms a sliding insertion fit with the bottom end of the conical cover 9.

[0024] The bottom end of the air supply pipe 14 is connected to a flip plate 19, and the middle part of the flip plate 19 has an air outlet 20 that communicates with the air supply pipe 14.

[0025] By opening the solenoid valve 18, carbon dioxide in the gas storage tank 8 can enter the gas supply pipe 14 along the connecting hose 13, and then enter the reaction container 2 from the gas outlet 20, thereby ensuring that the carbon dioxide in the reaction container 2 is sufficient, providing favorable conditions for the photosynthesis of algae. By extending and retracting the telescopic cylinder 11, the gas supply pipe 14 and the flipping plate 19 can be moved up and down. The flipping plate 19 is used to stir the nutrient solution, so that the nutrients are evenly distributed, thereby ensuring the growth rate and biomass yield of microalgae.

A temperature sensor 15 is installed on the lower end of the horizontal section of the L-shaped support plate 6 above the reaction vessel 2. A controller 5 is installed on one side of the vertical section of the L-shaped support plate 6. The electric heating wire 3 and the temperature sensor 15 are both electrically connected to the controller 5.

[0028] Temperature sensor 15 can detect the temperature of the nutrient solution in reaction vessel 2 and transmit the temperature information to controller 5. When the temperature is low, controller 5 controls the electric heating wire 3 to turn on to assist in heating the reaction vessel 2, thereby providing suitable temperature conditions for the growth of microalgae.
