Description
Technical field
The utility model relates to the energy-conservation electric supply installation of a kind of greenhouse electric supply installation, particularly biogas power generation.
Background technology
In the greenhouse power supply, generally be civil power at present by power supply administration.The power plant power supply needs to consume a large amount of energy, as resources such as coals.The energy is as China's the lifeline of economy, and the power of social development has been subjected to the great attention of government.Yet, account for world energy sources and supply with its reserves of fossil fuel exhaustion day by day of 90%.Moreover, fossil fuel is also serious is polluting environment, because the CO that the fossil fuel burning is emitted
2Be to produce the topmost gas of greenhouse effect.
China is implementing the energy-saving and emission-reduction policy energetically, and Renewable Energy Development is the important behave of China.And but China's agricultural wastes resource is widely distributed, and such as stalk, industrial organic waste water, fowl and livestock farm waste water, domestic waste etc. all are the fuel that can produce regenerative resource.A kind of approach that utilizes biogas can be used as to curb environmental pollution both can be administered pollution, can obtain the energy and fertilizer again.The biogas power generation tool is energy-conservation, advantages such as environmental protection, and therefore developing the biogas power supply, to be used for the greenhouse power supply be a good measure.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of greenhouse energy saving electric supply installation based on biogas power generation, and it is easy to use, and small investment is energy-conservation, environmental protection, whole day, all the period of time power supply.
Solving the scheme that technical problem of the present utility model adopts is: biogas generating pit inserts the gas engine of biogas behind tube of pressure-stabilizing, empty filter and blender by pipeline, gas engine and generator are in transmission connection, the output of generator is connected with the load in greenhouse, and the output of generator also connects storage battery by rectification charger.
The technical solution of the utility model also comprises:
Biogas inlet front-end pipelines at tube of pressure-stabilizing is equipped with filter, is connected to flame arrester and explosion-proof valve and its exit position is other, and the other end of flame arrester is connected on the filter outlet place; The air intake of blender is equipped with the sky filter.
On the port of export pipeline of described biogas generating pit flowmeter, Pressure gauge, ball valve and cut-off electromagnetic valve are housed also; At the also other ball valve that is connected to of the port of export of tube of pressure-stabilizing.
Described generator adopts threephase alternator, and generator output end is respectively arranged with the joint of three-phase load and single-phase load; The output of storage battery inserts the three-phase output line of generator by inverter.
The effect of tube of pressure-stabilizing be pressure stability with the biogas of filter in certain pressure limit, the drain throgh ball valve that can open its exit falls a part of gas, and opens pressure release automatically when the time explosion-proof valve that the biogas pressure of system is excessive, prevents blast; The effect of flame arrester is to prevent the gas engine tempering, and the water seal in the conventional flame arrester can effectively cut off flame, avoids flame to light the biogas source unexpectedly and blast.
The biogas of tube of pressure-stabilizing mixes in blender with the air of the empty filter of process, as the fuel of engine.Biogas promotes the piston acting in the engine internal combustion, drives the generator rotation, and kinetic energy changes into electric energy.The electric energy of generator output is given the load power supply in greenhouse on the one hand, on the other hand unnecessary electric energy is stored in storage battery through rectification charger.If the biogas power supply is enough, then do not need storage battery power supply; If the fuel of biogas is not enough, just start the device of storage battery.The air switch that closes, storage battery can be transformed into direct current the 220V alternating current that the greenhouse load needs through inverter.The existing single-phase 220V of type of power supply also has the three phase supply of 380V, fully satisfies the dissimilar power supply of greenhouse load.
This practical beneficial effect is:
(1), all-weather power supply in 24 hours.When biogas can provide enough power supply to the supply load in greenhouse, just without accumulator plant.If biogas can not provide enough power supplys to the supply load in greenhouse, just start accumulator plant, greenhouse load power supply is replenished.
(2), protection environment.The fuel of traditional greenhouse power supply is resources such as coal, is easy to generate pernicious gas, destroys human habitat; And the house refuse in human city, industrial wastewater, the ight soil of fowl poultry etc. can change biogas into, turn waste into wealth, for Blast Furnace Top Gas Recovery Turbine Unit (TRT) provides fuel.
(3), energy savings.With common greenhouse, area, Kunming is example, and the greenhouse power load has 3 of blower fans, three phase supply, power of fan 1.1kw; 1 of heating machine, power is 0.55kw, 1 on water pump, single phase power supply, power are 2kw, the gross power of transducer is 2kw, single phase power supply, the gross power of light is 3kw, single phase power supply.Suppose that these equipment on average worked 4 hours every day, then can save electricity 43.4 degree electricity in one day, the electricity price in area, Kunming is 0.5 a yuan/degree, then saves 21.7 yuan of the electricity charge in one day, saves 7920.5 yuan in 1 year.
