Description
Technical field
The present invention relates to a kind of cogeneration system and technology of utilizing solar energy and biomass energy, is that a kind of solar low-temperature heat energy and biomass energy are efficiently utilized new method and technology, belongs to the energy and environment technical field.
Background technique
Electrical production is being played the part of more and more important role in industrial and agricultural production, we can say that power supply is the bottleneck of entire society's development.Since oneth century; Power industry all is seriously to depend on fossil fuel such as coal, though in recent years along with The Application of Technology such as overcritical Rankine cycles, the coal electrical efficiency progressively improves (state-of-the-art technology can reach nearly 50% the thermal efficiency in the world now); But power industry still is carbon dioxide and the main emission source of the serious environmental contaminants of sulfur dioxide; Along with the exhaustion of fossil fuel, the cost of exploitation and difficulty can be increasing simultaneously, therefore strengthen the dynamics to new energy development; Thereby alleviating national product and the life process degree of dependence to fossil fuel gradually, is the unique selection that the mankind must face.
The radiation power of the sun reaches 3.8x10
23KW, wherein, about 1.08x10
14KW is radiated earth surface, even if light-photoelectric transformation efficiency be merely ten thousand/, also can reach nearly 4 times more than of whole world total power generating capacity.It is estimated that the sun is radiated tellurian energy within January, can support all non-renewable energy resources gross reserves that comprise fossil fuel, atomic power etc. on the earth 10 times more than, solar energy is really inexhaustible, the nexhaustible energy.China belongs to the quite abundant country of solar energy resources, and 2/3 area year sunshine duration of area is greater than 2200h, and unit area solar radiation total amount is higher than 5016MJ/m

2With 114 tons of NO
xDischarging.But the initial cost of high temperature solar heat power generating system is high; Usually be several times as much as the thermal power generation system of same electric motor power; Equipment, material are also had very high requirement, and installation period is longer, these unfavorable factors have all seriously restricted the construction and the investment of high temperature solar heat power generating system.
Biomass resource refers to that mainly agricultural and forest products industry waste, livestock breeding industry ight soil and city contain the solid waste of combustible component.There is abundant biomass resource in China, according to statistics China rural area just (calorific value about 10.2 * 10 up to 700,000,000 tons of the straw amount of abandoning only
15KJ), nearly 200,000,000 tons (calorific values about 3.1 * 10 of forest products industry waste
15KJ), agricultural wastes such as a large amount of rice husks, stalk are still arranged.If these wastes are unreasonable to be recycled, just can become the ring harmful substances.Current biomass energy utilization technologies mainly contains: directly burning, and heat that burning produces and steam can be used for generating, or to user's heat supply; Biogas technology, the biogas that living beings produce can be used as life combustion gas and generating; Biomass gasification technology, the combustible gas that gasification is produced can be used for cooking, heating and used for drying corps, also can be used as the fuel of internal-combustion engine, gas turbine equal power device, output power or power; The biomass pyrolytic technology is divided into destructive distillation system water gas, charcoal processing and fast pyrogenation system bio oil technology; The biomass liquefying technology.As a whole, agricultural and forest products industry living beings need to absorb CO in growing process
2Carry out photosynthesis, the using energy source of this biolobic material and conversion system can not cause CO in the earth atmosphere
2The increase of total amount, therefore, the research of biomass energy utilization technologies has become the focus of international community's new energy technology research.At present, the clean combustion of living beings technology has become ripe like production and use of marsh gas technology, straw gasifying technology etc., and Related product is just progressively realized the typing marketization.
Low-temperature solar energy and the biomass energy of being coupled effectively makes up cogeneration system, can realize having complementary advantages between solar energy and biomass energy, guarantees the stability and the high efficiency of energy source conversion system, is expected to become the important technique measure that makes up the distributed energy supply system.
