Embodiment approach 1

[0035] Photosynthetic microorganism CO from microalgae 2 Optical fiber bundle LED bioreactor includes reactor, optical fiber bundle LED microalgae source photosynthetic microbial light source, flue CO 2 Gas dispersion lifts the agitator, heat preservation system, feeding and discharging system and pH control system operating unit, etc. Microalgae source photosynthetic microorganism culture solution enters through raw material pump figure 1 The reaction device is used to access photosynthetic microorganisms from microalgae through an inoculation inlet. The flue gas treated by dust removal is accelerated by the gas dispersing and lifting agitator to dissolve the gas, stir and mix, so that the carbon dioxide in the flue gas enters the reactor at an appropriate ratio. system, irradiating the surface of photosynthetic microorganisms with high density of microalgae. CO 2 The Fiber Optic Bundle LED Photobioreactor can be used as a single stage. At the same time, CO 2 The growth...

Embodiment approach 2

[0039] Embodiment 2 is basically the same as Embodiment 1, the difference is that CO 2 Optical fiber bundle LED photobioreactors can be used in two-stage series or parallel. After dedusting the flue gas, the CO is dispersed through the gas 2 The gas is evenly dispersed in the reactor, and through the LED algae light source as the light source and the optical fiber as the light energy dispersion system, the surface of the photosynthetic microorganisms with high density of microalgae is irradiated to promote the flue gas CO 2 purify. Microalgae source photosynthetic microbial cells are carried out under high culture density and separated by centrifugation, so that products with good quality can be obtained. The photosynthetic microbial cells from microalgae are centrifuged and washed, the wet bacteria are crushed, and chlorophyll and other useful substances are extracted by vibration with organic extractants. The organic extract is recovered by rotary evaporation to obtain th...

Embodiment approach 3

[0041] Embodiment 3 is basically the same as Embodiment 2 and Embodiment 1, the difference is that CO 2 Optical fiber bundle LED photobioreactors can be used in series or parallel in multiple stages. The combination of photosynthetic microorganisms from microalgae and environmental purification technology can purify CO in the flue gas of large coal-fired factories by adjusting the pH, the growth factor of photosynthetic microorganisms from microalgae, and the dilution ratio of flue gas to air. 2 , NO x and SO x . The resulting biomass can be utilized as a renewable energy source or directly as feed.

Abstract

The invention discloses a device for purifying flue gas by utilizing microalgae source photosynthetic microorganisms and a method thereof, which relate to environmental biological resource engineering. An LED microalgae source photosynthetic microorganism friendly illuminant of the system conducts light wave produced by an LED to the surfaces of the microalgae source photosynthetic microorganisms through light propagation media-optical fiber, and the microalgae source photosynthetic microorganisms utilize the photosynthesis to purify pollution gas such as CO2 in the flue gas dispersed in a microalgae source photosynthetic microorganism culture fluid containing growth factors so as to produce a large quantity of the microalgae source photosynthetic microorganisms as well as purify atmospheric pollutants simultaneously, wherein the microorganisms contains chlorophyll, protein and other useful organic substances. The device and the method recycle the pollutants, namely improve the efficiency of energy utilization, also eliminate the pollution, and have a green process with stronger practicability. The method has the advantages of less equipment investment, easy operation and high culture density of the microalgae source photosynthetic microorganisms in a reactor, and performs the resource utilization on the pollutants as well as purifies the pollutants simultaneously.

Description

technical field [0001] The invention relates to an environmental biological resource engineering, in particular to a microalgae source photosynthetic microorganism CO 2 An optical fiber bundle LED photobiological reaction flue gas purification device and a method for purifying flue gas by using photosynthetic microorganisms from microalgae sources. Background technique [0002] The increase in consumption of fossil fuels such as coal and oil not only contributes to air pollution (NO x , SO x ) and acid rain, and a large amount of greenhouse gases (CO 2 ). CO 2 It can absorb solar infrared radiation, increase the temperature of the earth's atmosphere, cause abnormal evolution of the global environment, and endanger the existence and development of life systems. Greenhouse gas from CO 2 、CH 4 、CFC x , NO 2 and other gases, the main component of which is CO 2 . In order to explore the impact of greenhouse gases on global climate and environment change, people have ca...
