[0002] Through long-term observation, it is found that there are still some problems in the common microalgae cultivation process at home and abroad, such as large area, easy pollution, and easy wall adhesion of microalgae. In addition, the treatment of CO2 generated in the operation of large factories is also a major problem. my country's annual carbon dioxide emissions are about 10 billion tons. Energy, chemical, building materials, petrochemical and other industries will produce a large amount of flue gas in the production process, emitting a large amount of carbon dioxide, causing a greenhouse effect. Therefore, using microalgae to treat CO2 in flue gas is one of the directions to solve the problem. According to the survey, most of the cultivation devices for large-scale cultivation of microalgae in the market are open runway pools, that is, pools built with cement. This runway pool has a low yield, and the efficiency of using microalgae to treat carbon dioxide in flue gas is low. Therefore, the existing microalgae photobioreactors are insufficient in terms of large-scale cultivation and carbon fixation efficiency. Utility Model Content

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention.

[0024] Example 1

[0025] like Figure 1-4 As shown, this embodiment provides a racetrack-type photobiological reaction and efficient carbon fixation combined device, which utilizes the microalgae's own proliferation and metabolism process to purify flue gas while also harvesting microalgae biomass energy, thereby coupling flue gas purification with microalgae energy production and achieving flue gas resource utilization. Specifically, Figure 1-2 As shown, in this embodiment, the runway-type photobiological reaction and efficient carbon fixation combined device includes a support frame, which includes three rectangular support plates 101 spaced apart from top to bottom, and the support plates 101 are fixedly connected by support columns 102. The bottom of the lowest support plate 101 is also provided with support columns 102 to support the support frame on the ground; the support columns 102 are arranged at the four corners of the support plate 101.

[0026] like Figure 1-2As shown, a circular runway pool 2 is provided on each support plate 101, and the runway pool 2 is made of acrylic plate material. The top runway pool 2 is connected to a water inlet pipe 301, and adjacent runway pools 2 are connected by a branch pipe 302, and the bottom runway pool 2 is connected to a water outlet pipe 303. When in use, water is passed into the top runway pool 2 through the water inlet pipe 301, and the water then flows into the two runway pools 2 below through the branch pipe 302 in turn; when the water in the runway pool 2 is replaced regularly, the water in the runway pool 2 can be discharged by simply opening the water outlet pipe 303.

[0027] At the same time, the raceway pool 2 is provided with a stirring mechanism, specifically, as Figure 1-4 As shown, the stirring mechanism includes a transmission shaft 401 arranged on the runway pool 2, the transmission shaft 401 is connected to a driving mechanism, and a stirring paddle 402 is arranged on the transmission shaft 401. More specifically, the driving mechanism includes driven gears 501 arranged at both ends of the transmission shaft 401, and three driven gears 501 on the same side are connected to a driving gear 502 through a chain, and the driving gear 502 is driven to rotate by a reducer and a motor, wherein the driving gear 502, the reducer and the motor are located below the lowest runway pool 2. At the same time, two groups of stirring paddles 402 are symmetrically arranged on the transmission shaft 401, and each group of stirring paddles 402 includes four stirring blades 4021 evenly spaced. Through the rotation of the stirring paddle 402, the sedimentation and wall-attached growth of microalgae can be prevented, which effectively alleviates the problems of slow growth of microalgae and low carbon fixation.

[0028] In addition, if Figure 3 As shown, an LED lamp tube 6 is arranged at the center of the runway pool 2, and two arc-shaped transparent light panels 7 are symmetrically arranged on both sides of the LED lamp tube 6. This embodiment uses transparent light panels 7 to cooperate with the LED lamp tube 6, which can reduce the impact of environmental factors on the device and improve the efficiency of light energy utilization.

[0029] A spherical aerator 8 is also provided in the runway pool 2. Flue gas is pumped into the spherical aerator 8 by an air pump, and the flue gas then enters the runway pool 2 through the spherical aerator 8. The carbon dioxide therein can be fully mixed with the algae liquid to achieve the effect of efficient carbon fixation and promoting the growth of microalgae.

[0030] Working principle:

[0031] Water is passed into the three-layer runway pool 2 through the water inlet pipe 301, the motor and the reducer are started, and the stirring paddle 402 is driven to rotate through the driving gear 502 and the driven gear 501, so as to prevent the microalgae from settling and growing on the wall; at the same time, the LED lamp tube 6 is turned on, and combined with the transparent light board 7, the impact of environmental factors on the device can be reduced and the efficiency of light energy utilization can be improved. Flue gas is pumped into the spherical aerator 8 through the air pump, and the flue gas enters the runway pool 2 through the spherical aerator 8, and the carbon dioxide therein can be fully mixed with the algae liquid to achieve the effect of efficient carbon fixation and promoting the growth of microalgae.

[0033] The device of the utility model is applied to the large-scale cultivation of microalgae, which can increase the yield of microalgae per unit area, increase land utilization rate, and improve income. While cultivating microalgae on a large scale, the device of the utility model can also use microalgae to treat carbon dioxide in flue gas, and while using the microalgae's own proliferation and metabolism process to purify flue gas, it can also harvest microalgae biomass energy, realize the coupling of flue gas purification and microalgae production capacity, and achieve the resource utilization of flue gas.
