As photosynthetic carbon fixation microorganisms, microalgae have a much higher photosynthesis efficiency than other terrestrial plants, which is ten to fifty times that of other plants. At present, the light energy conversion efficiency of microalgae carbon fixation is about 1%, which is a huge gap compared to the theoretical value of about 12%. The light energy conversion efficiency is affected by many factors, such as microalgae concentration, carbon dioxide flow, microalgae growth conditions, etc.

[0003] The microalgae carbon fixation device in the prior art includes: a carbon capture device, an algae bioreactor unit and a plant cultivation unit.

By combining microalgae cultivation and plant cultivation, different concentrations of carbon dioxide can be utilized in a gradient, so that the first photosynthesis and the second photosynthesis are both carried out at a more suitable carbon dioxide concentration, thereby greatly improving the utilization rate of carbon dioxide and at the same time increasing the amount of biological carbon fixation.

[0038] When carbon dioxide is supplied, the controller may receive the microalgae concentration information in the microalgae holding box 12 measured by the microalgae concentration measuring component 14 in the self-elevating microalgae holding device 10, and trigger the carbon dioxide supply device 30 according to the microalgae concentration information to input carbon dioxide gas from the microalgae conveying device 20 into the microalgae solution at an appropriate flow rate;

[0040] Furthermore, when the self-lifting microalgae containing device 10 is working, the microalgae solution in the microalgae containing box 12 at the upper part flows from the microalgae conveying device 20 into the microalgae containing box 12 at the lower part under the action of gravity. After the microalgae solution in the microalgae containing box 12 at the upper part flows out, the microalgae containing box 12 at the upper part descends, and the microalgae containing box 12 at the lower part ascends. After completion, the microalgae solution can continue to flow under the action of gravity.

[0042] Furthermore, when the first connecting component 22 and the second connecting component 13 are working, the electromagnetic disk 131 in the first connecting component 22 and the electromagnetic disk 131 in the second connecting component 13 are powered on and magnetically attracted to each other to complete the connection, and are separated after power is turned off;

[0043] Furthermore, when the microalgae concentration determination component 14 is working, the execution end of the micro electric cylinder 143 drives the plunger plate 144 to move, the microalgae solution enters the sample tube 142 through the sampling plate 141, the light source emitter 146 emits a light beam to the sample tube 142, the imaging sensor 147 receives the light emitted by the light source emitter 146 and transmits it to the controller, the controller receives the light information collected by the light source emitter 146, and obtains the microalgae concentration information after analysis;

[0044] Furthermore, when the discharge component 15 is working, when it is necessary to adjust the concentration of the microalgae solution in the microalgae holding box 12 or replace the microalgae solution in the microalgae holding box 12, the controller triggers the discharge component 15 to discharge a set amount of microalgae solution.

[0046] Please refer to the attached Figure 1 , 3 As shown in Figures 6 and 9, in another preferred embodiment of the present invention, it also includes a carbon dioxide supply device 30 whose output end is connected to both ends of the microalgae transport pipeline 21 and a microalgae concentration adjustment supply device 40, the carbon dioxide supply device 30 includes a first electrically controlled valve 31, a carbon dioxide gas source pipe 32 provided at the input end of the first electrically controlled valve 31, a carbon dioxide transport pipeline 33 whose input end is connected to the output end of the first electrically controlled valve 31 and whose output end is connected to both ends of the microalgae transport pipeline 21, and a plurality of microbubblers 34 provided on the inner wall of the microalgae transport pipeline 21 and corresponding to the position of the output end of the carbon dioxide transport pipeline 33, the microbubbler 34 includes a first leak hole spring piece 341 whose one end is connected to the inner wall of the microalgae transport pipeline 21, a second leak hole spring piece 342 obliquely provided at the end of the first leak hole spring piece 341, and an elastic rubber sheet 343 whose bottom is connected to the outer walls of the first leak hole spring piece 341 and the second leak hole spring piece 342 and whose top is connected to the inner wall of the microalgae transport pipeline 21.

[0047] It should be noted that, in this preferred embodiment, when the carbon dioxide supply device 30 is working, the carbon dioxide gas source pipe 32 can be connected to the carbon dioxide supply system, and the carbon dioxide gas can enter the first electric control valve 31 through the carbon dioxide gas source pipe 32 and then enter the microalgae delivery pipeline 21 in the microalgae delivery device 20 through the carbon dioxide delivery pipeline 33, and enter the microalgae delivery pipeline 21 through one end of the microalgae delivery pipeline 21 close to the microalgae containing box 12 located at the upper part, and the carbon dioxide gas enters the microalgae solution after generating bubbles through the microbubble device 34;

[0048] Furthermore, when the microbubble device 34 is working, the gas passes through the second leak hole spring piece 342 and enters the microalgae solution to generate bubbles. When the input amount of carbon dioxide gas increases, the gas pressure drives the second leak hole spring piece 342 to move downward, and the second leak hole spring piece 342 drives the first leak hole spring piece 341 to move, so that the first leak hole spring piece 341 is separated from the inner wall of the microalgae conveying pipeline 21, and the carbon dioxide gas can enter the microalgae solution through the first leak hole spring piece 341 and the second leak hole spring piece 342.

[0050] It should be noted that, in this preferred embodiment, the microalgae concentration detector corresponding to the microalgae cultivation box 41 can transmit the microalgae concentration information in the microalgae cultivation box 41 to the controller. When adjusting the microalgae concentration, the controller triggers the switch at the discharge end of the microalgae cultivation box 41 according to the microalgae concentration information of the microalgae cultivation box 41, so as to discharge an appropriate amount of microalgae solution of corresponding concentration into the microalgae concentration adjustment box 42. The microalgae concentration adjustment component 43 in the microalgae concentration adjustment box 42 adjusts the microalgae concentration until the microalgae concentration reaches the set value. After the adjustment is completed, the controller triggers the air source system connected to the microalgae cultivation box 41 to increase the pressure in the microalgae cultivation box 41, so that the microalgae solution enters the microalgae delivery pipeline 21 through the electric control valve and the concentration adjustment delivery pipeline 44, and enters the microalgae delivery pipeline 21 through the end of the microalgae delivery pipeline 21 close to the microalgae containing box 12 located above.

[0051] Furthermore, when the microalgae concentration regulating component 43 is working, the controller can obtain the liquid level information in the microalgae concentration regulating box 42 through the liquid level sensor in the microalgae concentration regulating box 42. When the microalgae concentration in the microalgae concentration regulating box 42 needs to be reduced, liquid can be injected through the liquid supply system connected to the input pipe 436 to reduce the concentration. When the microalgae concentration in the microalgae concentration regulating box 42 needs to be increased, the actuator end of the power cylinder 431 drives the plunger type lifting frame 432 to descend, and the excess liquid is filtered by the filter membrane 433 and then moved into the upper part of the filter membrane 433. The negative pressure system connected to the output pipe 437 is turned on, and the excess liquid is discharged through the control pipe 434, the solenoid valve 435 and the output pipe 437.

[0052] Furthermore, the microalgae concentration regulating component 43 can absorb more liquid when absorbing liquid, so as to ensure the accuracy of the microalgae concentration after eluting by the eluting component 438. When the eluting component 438 is working, the liquid source system connected to the liquid source tube 4383 inputs liquid into the liquid source tube 4383. The liquid is ejected after passing through the liquid source tube 4383, the delivery channel 4382 and the eluting tube 4381, and the filter membrane 433 is rinsed to prevent the microalgae from adhering to the filter membrane 433.

[0053] The working principle of the present invention is:

[0054] The electrical components in the present invention are all triggered to operate by the PLC controller;

[0055] When the device is performing carbon fixation, the two self-elevating microalgae containing devices 10 are alternately raised and lowered so that the microalgae solution passes through the microalgae conveying device 20 under the action of gravity;

[0056] When carbon dioxide is supplied, the controller may receive the microalgae concentration information in the microalgae holding box 12 measured by the microalgae concentration measuring component 14 in the self-elevating microalgae holding device 10, and trigger the carbon dioxide supply device 30 according to the microalgae concentration information to input carbon dioxide gas from the microalgae conveying device 20 into the microalgae solution at an appropriate flow rate;

[0057] When adjusting the microalgae concentration, the controller can receive the microalgae concentration information in the microalgae holding box 12 measured by the microalgae concentration measuring component 14, and trigger the drainage component 15 and the microalgae concentration adjustment and supply device 40 when the microalgae concentration data value exceeds the set range. The drainage component 15 can discharge part of the microalgae solution in the microalgae holding box 12, and the microalgae concentration adjustment and supply device 40 automatically prepares the microalgae solution of appropriate concentration, and after the preparation is completed, the microalgae solution is input from the microalgae conveying device 20;

[0058] When the self-lifting microalgae containing device 10 is working, the microalgae solution in the microalgae containing box 12 at the upper part flows from the microalgae conveying device 20 into the microalgae containing box 12 at the lower part under the action of gravity. After the microalgae solution in the microalgae containing box 12 at the upper part flows out, the microalgae containing box 12 at the upper part descends, and the microalgae containing box 12 at the lower part ascends. After completion, the microalgae solution can continue to flow under the action of gravity.

[0059] The linear module 112 in the automatic lifting frame 11 can drive the microalgae holding box 12 to move up and down. During the process of the microalgae holding box 12 moving up and down, the second connecting component 13 is separated from the first connecting component 22 and the second electric control valve 134 in the second connecting component 13 is in a closed state. After the microalgae holding box 12 is moved up and down to a designated position, the first connecting component 22 is connected to the second connecting component 13 at the corresponding position, and the second electric control valve 134 in the second connecting component 13 at the corresponding position is opened to complete the lifting work.

[0060] When the first connecting component 22 and the second connecting component 13 are working, the electromagnetic disk 131 in the first connecting component 22 and the electromagnetic disk 131 in the second connecting component 13 are powered on and magnetically attracted to each other to complete the connection, and are separated after power is turned off;

[0061] When the microalgae concentration measuring component 14 is working, the execution end of the micro electric cylinder 143 drives the plunger plate 144 to move, the microalgae solution enters the sample tube 142 through the sampling plate 141, the light source emitter 146 emits a light beam to the sample tube 142, the imaging sensor 147 receives the light emitted by the light source emitter 146 and transmits it to the controller, the controller receives the light information collected by the light source emitter 146, and obtains the microalgae concentration information after analysis;

[0062] When the discharge component 15 is working, when it is necessary to adjust the concentration of the microalgae solution in the microalgae holding box 12 or replace the microalgae solution in the microalgae holding box 12, the controller triggers the discharge component 15 to discharge a set amount of microalgae solution. When the discharge component 15 is working, the third electrically controlled valve 152 is opened, and the microalgae solution can be discharged through the discharge pipe 151. The flow sensor 153 transmits the flow information to the controller, and the controller receives the flow information and closes the third electrically controlled valve 152 when the discharged liquid volume reaches the set value.

[0063] When the stirring component 16 is working, the actuator end of the power motor 164 drives the positioning plate 161 to rotate, the positioning tube 162 can stir the microalgae solution, and the lamp tube 163 can illuminate to provide light for the photosynthesis of the microalgae;

[0064] When the carbon dioxide supply device 30 is working, the carbon dioxide gas source pipe 32 can be connected to the carbon dioxide supply system, and the carbon dioxide gas can enter the first electric control valve 31 through the carbon dioxide gas source pipe 32, and then enter the microalgae delivery pipeline 21 in the microalgae delivery device 20 through the carbon dioxide delivery pipeline 33, and enter the microalgae delivery pipeline 21 through one end of the microalgae delivery pipeline 21 close to the microalgae containing box 12 located at the upper part, and the carbon dioxide gas enters the microalgae solution after generating bubbles through the microbubble device 34;

[0065] When the microbubble device 34 is working, the gas passes through the second leaking spring piece 342 and enters the microalgae solution to generate bubbles. When the input amount of carbon dioxide gas increases, the gas pressure drives the second leaking spring piece 342 to move downward, and the second leaking spring piece 342 drives the first leaking spring piece 341 to move, so that the first leaking spring piece 341 is separated from the inner wall of the microalgae transport pipeline 21, and the carbon dioxide gas can enter the microalgae solution through the first leaking spring piece 341 and the second leaking spring piece 342.

[0066] The microalgae concentration detector corresponding to the microalgae cultivation box 41 can transmit the microalgae concentration information in the microalgae cultivation box 41 to the controller. When adjusting the microalgae concentration, the controller triggers the switch at the discharge end of the microalgae cultivation box 41 according to the microalgae concentration information of the microalgae cultivation box 41, so as to discharge a suitable amount of microalgae solution of corresponding concentration into the microalgae concentration adjustment box 42. The microalgae concentration adjustment component 43 in the microalgae concentration adjustment box 42 adjusts the microalgae concentration until the microalgae concentration reaches the set value. After the adjustment is completed, the controller triggers the air source system connected to the microalgae cultivation box 41 to increase the pressure in the microalgae cultivation box 41, so that the microalgae solution enters the microalgae delivery pipeline 21 through the electric control valve and the concentration adjustment delivery pipeline 44, and enters the microalgae delivery pipeline 21 through the end of the microalgae delivery pipeline 21 close to the microalgae containing box 12 located above;

[0067] When the microalgae concentration regulating component 43 is working, the controller can obtain the liquid level information in the microalgae concentration regulating box 42 through the liquid level sensor in the microalgae concentration regulating box 42. When it is necessary to reduce the microalgae concentration in the microalgae concentration regulating box 42, liquid can be injected through the liquid supply system connected to the input pipe 436 to reduce the concentration. When it is necessary to increase the microalgae concentration in the microalgae concentration regulating box 42, the execution end of the power cylinder 431 drives the plunger type lifting frame 432 to descend, and the excess liquid is filtered by the filter membrane 433 and then moved into the upper part of the filter membrane 433. The negative pressure system connected to the output pipe 437 is opened, and the excess liquid is discharged through the control pipe 434, the solenoid valve 435 and the output pipe 437.

[0068] When the microalgae concentration regulating component 43 absorbs liquid, it can absorb more liquid to ensure the accuracy of the microalgae concentration after elution by the elution component 438. When the elution component 438 is working, the liquid source system connected to the liquid source tube 4383 inputs liquid into the liquid source tube 4383. The liquid is sprayed out after passing through the liquid source tube 4383, the delivery channel 4382 and the elution tube 4381, and the filter membrane 433 is rinsed to prevent microalgae from adhering to the filter membrane 433.
