Abstract
It is a kind of from oxygen uptake formula tubular type bioreactor, including tubular type bioreactor and drum like alkaline fuel cell unit, described tubular type bioreactor includes light reaction pipe, fluid reservoir and water circulating pump, algae solution is driven by water circulating pump and circulated in light reaction pipe and fluid reservoir, and cylindrical type alkaline fuel cell is installed in the junction between light reaction pipe；The present invention is handled the algae solution of the high dissolved oxygen amount in bioreactor using the Cathodic oxygen reduction of fuel cell, in the case where ensureing algae solution high-efficient culture, the aerator traditional without tubular type bioreactor, while anode of fuel cell oxidation produces CO2As the carbon source of algae solution, its electric energy produced can act also as the power supply of additional light source, reach the purpose of reduction system energy consumption.
Description
Technical field
Field is sealed up for safekeeping the invention belongs to bioengineering and carbon dioxide capture, and in particular to one kind collection algae high-efficient culture,
CO2Capture, dissolved oxygen effect suppress and dissolved oxygen is recycled in integral from oxygen uptake formula tubular type bioreactor.
Background technology
Since 21 century, energy crisis has turned into the key subjects that the whole mankind faces with environmental pollution.Especially at me
State, as economic develops rapidly, people's living standard constantly rises, and the serious hope to the energy is increasingly urgent, traditional fossil energy
The supply breach in source is increasing.According to relevant report, Chinese crude oil external dependence degree in 2015 is first more than 60%, such case
Seriously threaten national security.In addition, China in 2015 occurs in that 11 a wide range of, the haze processes of continuation, fossil energy
The serious environmental pollution that the utilization in source is caused highly significant had influence on daily life with it is healthy.
Under this background, the new cleaning fuel such as solar energy, wind energy, biomass energy is widely studied to substitute high pollution once
The energy.
Biodiesel has widely been utilized in the world as the alternative fuel of oil, and development biodiesel is most
What crucial the problem of was raw material carrys out source problem, wherein the microalgae of high oil-containing does not have the limitation of season and production cycle, and comes
Source is abundant be considered as biodiesel quality raw materials.Microalgae has the photosynthesis more efficient than traditional crop, by carbon water
CO in compound, hydrocarbon and air2A large amount of greases are synthesized as carbon source, the High Density Cultivation of microalgae is to realize microalgae
The key that resource synthetic development is utilized, can be with open culture and closed culture.
Bioreactor refers to the Experimental Establishment for cultivating the plant tissue with photosynthetic capacity, cell, leads to
Cross control temperature, pH, intensity of illumination, nutrient solution concentration, CO2Deng continuous or semi-continuous culture is carried out, so as to obtain higher
Biological density or yield per unit area.In tubular type bioreactor, oxygen is that algae carries out photosynthetic product.But
It is, in CO2In the case that concentration is higher, the dissolved oxygen for the high concentration that photosynthesis is produced can destroy frustule, suppress algae thin
The growth of born of the same parents.In algae solution, dissolved oxygen is O in air2Saturation degree (7.5mLL-1, 30 DEG C) in the case of, the tolerance of frustule
