It can be used without limitation if it is microalgae with

A water trap 210 may be disposed on the movement line of the processing gas discharged through the light culture process unit 200 to remove moisture contained in the first processing gas. The first treatment gas discharged from the microalgae light culture process is in a wet and saturated state. Moisture is removed from this first process gas passing through the water trap 210 , and the first process gas from which moisture is removed may move to the mixing tank 300 .

When the second processing gas flows through the plurality of separation membranes, the separation membrane process unit 400 separates the gas into a concentrated gas mainly composed of nitrogen, oxygen, and carbon dioxide due to the separation pore difference and permeation rate of each component. have.

The separation membrane processing unit 400 may separate the first concentrated gas, the second concentrated gas, and the third concentrated gas using the first separator 410 , the second separator 420 , and the third separator 430 .

In one embodiment, the second processing gas introduced from the mixing tank 300 moves the mixed gas of the first concentrated gas and the second concentrated gas separated in the first separation membrane 410 to the second separation membrane 420 , The mixed gas of the second concentrated gas and the third concentrated gas may be moved to the third separation membrane 430 . Thereafter, the first concentrated gas and the second concentrated gas may be separated in the second separation membrane 420 , and the second concentrated gas and the third concentrated gas may be separated in the third separation membrane 430 . Thereafter, the second concentrated gas separated from the second separator 420 and the third concentrated gas separated from the third separator 430 are collected in one pipe and moved.

The first concentrated gas, the second concentrated gas, and the third concentrated gas separated through the plurality of separation membranes may be utilized within the system.

At this time, the first enriched gas may have a nitrogen content of 95 to 99%, the second enriched gas may have an oxygen content of 80 to 90%, and the third enriched gas may have a carbon dioxide content of 85 to 95%.

The mineralization reaction unit 500 may use the third concentrated gas separated in the separation membrane process unit 400 to mineralize carbon dioxide and discharge the third processing gas to the mixing tank 300 .

The mineralization reaction unit 500 is a technology for synthesizing the captured carbon dioxide into a new mineral by reacting it with natural minerals or inorganic industrial waste discharged from industries.

In one embodiment, the mineralization reaction unit 500 is carbon dioxide in the exhaust gas through the mineralization reaction with Ca and Mg components in the building by-products (slag, waste concrete) to produce CaCO ₃ , MgCO ₃ and carbonate to produce carbon dioxide permanently can be solidified with

The carbonate produced is stable and does not dissolve well in water, it is not harmful to the environment because it is impossible to release carbon dioxide into the atmosphere, and it is possible to solve the problem of carbon dioxide emission by permanently storing carbon dioxide.

At this time, the first concentrated gas containing high-purity nitrogen gas is microbubbled through a fine disperser and injected into the mineralization reaction unit 500 , and reacts with the third concentrated gas supplied to the mineralization reaction unit 500 . Thus, the inside of the mineralization slurry tank can be uniformly mixed.

In one embodiment, the first concentrated gas containing nitrogen gas concentrated to 98% is introduced into the mineralized waste cone fine powder slurry tank and sprayed, and is effectively mineralized through uniform mixing and maintenance effect due to the sprayed fine nitrogen bubbles. can cause a reaction to occur.

In addition, the oxygen-enriched second enriched gas may increase profits by selling high-concentration oxygen gas, or may be supplied to the light culture process unit 200 to promote microalgae culture.

The second enriched gas containing oxygen enriched to 85% may be supplied to the light culture process unit 200 and used as an accelerator to improve the growth rate of microalgae.

As an example, referring to FIG. 4 , in the case of culturing chlorella for 15 days in the light culture process unit 200 , a biomass concentration of 2.6 g/L is shown in the conventional process.

When injecting the second enriched gas containing oxygen in an embodiment of the present invention, when injecting the second enriched gas at 10m ³ /h 2.5g/L, when injecting at 20m ³ /h 2.8g/L, when injected into a 30m ³ / h in case of injecting 3.1g / L, 50m ³ / h in case of injecting 3.3g / L, 70m ³ / h in case of injecting ^{2.7g / L, 100m 3 / h} 2.3g / It can be confirmed that L biomass is generated. When oxygen gas is injected as a facilitator, it can be confirmed that the biomass growth rate increases up to a certain area, and ^{when it exceeds 50 m 3} /h, it can be confirmed that the growth rate decreases.

Therefore, in the present invention, the supply amount of the second enriched gas is preferably determined at ^{45 to 55 m 3} /h, and may be supplied at ^{50 m 3 /h under optimal conditions.}

The control unit 700 is supplied and discharged to the blower 100, the light culture process unit 200, the mixing tank 300, the separation membrane process unit 400, and the mineralization process unit using the detection value of the sensor unit 600. It is possible to control the flow rate of the gas and the carbon dioxide content.

An object of the present invention is to control exhaust gas emission by finally controlling the amount of carbon dioxide emitted.

However, since the amount of carbon dioxide introduced or the amount of carbon dioxide to be treated is not always constant, there is a problem in that the amount of carbon dioxide finally discharged varies due to different treatment efficiency.

In the present invention, in order to solve this problem, when the carbon dioxide concentration detected by the fourth sensor 640 is higher than a preset value, the carbon dioxide emission can be adjusted by controlling the components of the system.

When the carbon dioxide concentration detected by the fourth sensor 640 is higher than the preset value, the controller 700 reduces the amount of exhaust gas introduced through the first blower 110, and the second blower ( 120) by increasing the amount of exhaust gas flowing into the photo-culture process unit 200 to lower the carbon dioxide concentration inside the mixing tank 300, thereby controlling the final amount of carbon dioxide discharged.

In addition, the control unit 700 may control the carbon dioxide concentration sensed by the fourth sensor 640 by increasing the recirculation rate of the separation membrane process unit 400 , and the amount of calcium carbonate injected into the mineralization reaction unit 500 . may be increased to control the carbon dioxide concentration sensed by the fourth sensor 640 .

In one embodiment, the carbon dioxide concentration in the exhaust gas detected by the first sensor 610 is 8%, and the carbon dioxide concentration detected by the fourth sensor 640 should be maintained at 1%, the fourth sensor 640 If the concentration of carbon dioxide detected in the system is 2~3%, it is necessary to lower the concentration of carbon dioxide emitted.

The control unit 700 decreases the amount of gas introduced into the first blower 110 (400 m ³ /min → 300 m ³ /min), and increases the amount of gas introduced into the light culture process unit 200 through the first blower 100 . (100 m ³ /min → 200 m ³ /min) and when the carbon dioxide concentration in the mineralization process unit is adjusted to 5.5% through the second sensor 620, the concentration of carbon dioxide measured by the third sensor 630 is (8 ~10%→6.5~8%) can be controlled.

In addition, by increasing the recirculation rate or the external circulation rate in the first to third steps inside the separation membrane process unit 400 or by increasing the calcium oxide (CaO) input or the recirculation rate compared to the carbon dioxide concentration measured by the fifth sensor 650 , the mineral The final concentration of carbon dioxide discharged through the fourth sensor 640 may be lowered by lowering the concentration of carbon dioxide in the treatment gas.
