Description
Technical field
The present invention relates to low-carbons and energy technology field to be adapted to township more particularly, to one kind using carbon dioxide as working medium
The change system that village is generated electricity using biomass as energy carbon dioxide recycle.
Background technique
Climate change has become one of the problem of influencing human survival and development, and a large amount of CO2 emission is considered
It is the main reason for leading to climate warming, China is as maximum developing country in the world, the non-renewable energy based on coal
With the secondary energy sources structure based on thermal power generation, with increasing rapidly for economic total volume, the CO of non-renewable energy and secondary energy sources2
Discharge has the characteristics that growth is fast, total amount is big, develops low-carbon energy especially renewable energy and new energy for reply climate change
Source has become the common recognition of people, and biomass power generation, solar power generation and supercritical carbon dioxide power generation etc. have received significant attention.
Today, biomass generation mature application, but since existing biomass power generation system is huge, invests also very
Height is unsuitable for that region is vast and the rural area that disperses, and the unsuitable long distance transportation of transportation cost problem, leads to a large amount of biology in addition
The abandoneds such as matter such as stalk, straw or on-site incineration seriously pollute environment, airflight safety are also influenced, although governments at all levels
Check supervisor severely in accordance with the law every year, but in still expensive or even short of electricity the rural area of the electricity charge, a large amount of biomass is dirty by the big region of on-site incineration
The event of dye air impact aviation safety still remains incessant after repeated prohibition.It traces it to its cause and is the absence of one kind and is adapted to vast rural biomass fermentation
Method for electrically.And on the other hand, investment all kinds of middle-size and small-size coal-fired fluidized bed furnaces, grate furnace, layer that only thousands of members to hundreds of thousands of members do not wait
