Low-temperature solar energy-biomass energy cogeneration system
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 2Therefore, the research solar energy generation technology is significant to the China and even the whole mankind's sustainable development.Solar electrical energy generation can be an electric energy with conversion of solar energy environment not being brought under any pollution and the public hazards situation, and solar electrical energy generation is described as following optimal generation mode.Press the difference of conversion regime, can be divided into photovoltaic generation and light-Re-electric dual mode, wherein, photovoltaic power generation technology is ripe, but its efficient is low, initial cost is high.Light-Re-power technology mainly refers to light collecting high temperature solar heating power generating, and the difference of pressing sunlight tracking system can be divided into two big types of uniaxiality tracking and double-axis tracking systems; Press the difference of heat collector type, can be divided into slot type system, tower system and dish formula system three major types.Light collecting high temperature solar heating power generating efficiency is high, single-machine capacity is big; The nine cover SEGS solar-powered thermal generating sets of on the desert, California, building like the U.S.; Maximum every cover generated output is 80 megawatts, and total power generating capacity reaches 354 megawatts, can satisfy 500,000 residents' energy demand; 2,300,000 barrels of crude oil of annual saving reduce by 15.5 ten thousand tons of CO 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.
