Description
Technical field
The utility model relates to technical field of new energies, particularly a kind of biomass-assisted solar generating device.
Background technique
Strengthen the development and use dynamics of biomass energy is lasting both at home and abroad in recent years, and with this emphasis as the new energy development, the Chinese government has also brought up to the critical positions that taps a new source of energy to the comprehensive utilization of biomass energy, strengthened to biomass energy the exploitation input, therefore, more and more urgent on the market for the demand of the new product that rationally utilizes biomass energy, new technology.
Prior biological matter combustion furnace mostly adopts traditional combustion manner, i.e. the direct mode of biomass burning, and this combustion manner thermal transition efficient is low, drops into highly, and dust pollution is serious, can not adapt to large-scale power generation needs.Also have some similar products like to enter China market abroad, but great majority also are to adopt traditional combustion manner, and early investment is big, the purchase cost height has limited the widespread adoption of biomass energy sources for generating electricity in China.
Along with the orderly propelling that China's urbanization is built, industrial, agriculture fast development, energy shortage increasingly sharpens, and energy consumption increases year by year, and annual growth rate is all between 20%-30%.But, the a lot of all also not development and use of renewable energy sources of China at present, biomass energy is exactly wherein one, China produces trillion tons of the about 4-5 of agricultural crop straw per year, living beings such as flowers and plants, discarded construction timber are no less than the total amount of stalk, and these renewable resourcess all are not utilized effectively, and this has not only wasted resource, pollute environment, also endangered the healthy of people simultaneously.In addition, along with improving constantly of China's rapid economic development and people's living standard, the form of energy shortage, scarcity of resources is more and more severeer, and global energy controversial issue has become one of global main factor leading to social instability, and the development and use new energy are extremely urgent.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of energy utilization rate high biomass-assisted solar generating device.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: biomass-assisted solar generating device, comprise steam turbine set and the generator that is connected steam turbine set, it is characterized in that: also comprise solar thermal collector and biomass gasifying furnace, the suction port of steam turbine set connects the low temperature boiler by pipeline, the water intake of low temperature boiler connects solar thermal collector by pipeline, the firing unit of low temperature boiler connects biomass gasifying furnace by pipeline, the air outlet of steam turbine set connects the vapour condenser by pipeline, and the vapour condenser connects the backwater mouth of low temperature boiler by water pump.
As further improvement of the utility model, solar thermal collector adopts ethanol as heat transfer medium.
It is 200-300 ℃ that described steam turbine set adopts intake temperature, and suction pressure is the low temperature steam turbine of 0.7-1.2MPa.
The intake temperature of low temperature steam turbine is generally between 200-300 ℃, suction pressure is generally about 1MPa, in the intake temperature of warm steam turbine generally between 320-560 ℃, suction pressure is generally about 3MPa, generally between 600-1000 ℃, suction pressure is generally more than 10MPa for the intake temperature of high-temperature steam turbine.
Heat transfer medium in the solar thermal collector adopts ethanol, and its temperature can be lifted to more than 200 ℃, can satisfy the operation demand of low temperature steam turbine set fully.
By day, under the situation of sunlight abundance at sunshine, cryogenic liquide ethanol at first enters solar thermal collector as heat transfer medium, and solar thermal collector absorbs sunlight, and the luminous energy that the sun closes is converted into heat transfer medium in the heat energy heating solar heat-collector.Cold ethanol after the solar thermal collector heating becomes 200-230 ℃ alcohol vapour, and alcohol vapour is in pipeline enters the low temperature boiler, after the low temperature boiler carries out voltage stabilizing with alcohol vapour, to steam turbine set output temperature and the comparatively constant alcohol vapour of pressure.Steam turbine set drives generator and generates electricity.The alcohol vapour that steam turbine set is discharged feeds back to the low temperature boiler after collecting through the vapour condenser.
Night or sunshine situation relatively poor in, cryogenic liquide ethanol enters in the low temperature boiler after heating up through solar thermal collector is preliminary.Biomass gasifying furnace gasifies living beings such as straw, wood chip, and living beings are converted into organic combustion gas.Organic combustion gas enters by pipeline in the firing unit of low temperature boiler burns, and the ethanol in the heating low temperature boiler, is 200-300 ℃ alcohol vapour with ethanol conversion.Again that pressure and temperature is the comparatively stable alcohol vapour of low temperature boiler is transferred to steam turbine set, the running of steam supply wheel unit.Biomass gasifying furnace is organic combustion gas with conversion of biomass material, burns then, and not only thermal transition efficient height, and can reduce the discharging of pollutants such as dust, help environmental protection.
In sum, the utlity model has and to fully utilize solar energy and biomass energy, reduce pollutant emission, improve the beneficial effect of the utilization ratio of new energy.
