Description
Technical field
The invention belongs to greenhouse gases recovery system field, be specifically related to biological fermentation and discard carbon dioxide recovery purification devices.
Background technology
CO
2belong to greenhouse gases.Due to CO
2a large amount of discharges of isothermal chamber gas, cause global warming, each fields such as the social economy of countries in the world are had a negative impact, it can cause the generation of the such as phenomenon such as shortage of water resources, living environment worsens, financial loss is aggravated, sea level rise, heat wave attack increase, human health is subject to serious threat, also may cause the aggravation that species change in addition.According to the data presentation of International Energy Agency (IEA), except the impact of economic crisis in 2009, the CO of global year discharge over the years
2gas gross all shows a rising trend, CO
2concentration significantly increases, and result in serious Greenhouse effect.In order to contain global warming trend, various countries negotiator once repeatedly gathered, and successively have passed Kyoto Protocol, " Copenhagen agreement ", was intended to reduce CO
2discharge, controls global temperatures lift velocity.China became world CO from 2005 later
2annual emissions first big country.Current China is still in the high speed development stage, CO
2year generation will continue to rise.As world economy power and political big country, China faces CO
2the huge responsibility reduced discharging and pressure.Therefore, control greenhouse gas emission, effectively carry out CO
2it is imperative, very urgent that the research catch recovery, transporting and store and industrialization transform.
Grain distillery of China is with starchiness non-grain crop raw material production edible ethanol mostly, and fermentation is one of core process of alcohol enterprise production.Yeast changes into ethanol sugar during the fermentation, also produces carbonic acid gas simultaneously, and its total reaction equation is:
C
6h
12o
6+ enzyme → 2C
2h
5oH+2CO
2
Carbonic acid gas is the main by product produced in Alcohol Production fermenting process as can be seen from the above equation, often produce 1 ton of alcohol and can obtain carbonic acid gas about 0.96 ton in theory, in zymamsis gas, the concentration of carbonic acid gas is higher, can more than 95% be reached, its impurity is alcohols, aldehydes, ester class and trace oxygen, is beneficial to and produces highly purified food-grade carbon-dioxide.To produce the grain distillery of alcohol 100,000 tons per year, its production process can produce carbonic acid gas 90,000 tons year.The direct discharge of carbonic acid gas not only endangers environment, is also a kind of wasting of resources in fact.If this partial CO 2 can be reclaimed, no matter be discharge protection of the environment being reduced to greenhouse gases, or be all highly significant to the benefit of enterprise.
Summary of the invention
The present invention is directed to the present situation such as direct emission hazard environment, the wasting of resources that starchiness non-grain crop produces the carbonic acid gas produced in the industry of ethanol, carry out the recovery of byproduct carbonic acid gas and the research of purification, a kind of biological fermentation is provided to discard carbon dioxide recovery purification devices, " fine purifiation, adsorption dry and low temperature fractionation combination process " is adopted to produce food-grade carbon-dioxide, improve the added value of carbon dioxide by-product, simultaneously for industry reduces the exemplary role that professional is played in greenhouse gas emission.
