Description
Technical field
The present invention relates to a kind of power generation system, particularly a kind of methane power generating system of digital variable air input.
Background technique
At present, recycling economy requires renewable energy sources is paid attention to more, once produce, comprise that the industry through producing a large amount of biogas in the environmental protection treatment process is innumerable, and the Main Ingredients and Appearance of biogas is a methane, methane is one of six kinds of greenhouse gases listing of Kyoto Protocol, and its greenhouse effect are 21 times of carbon dioxide.If biogas is directly discharged in atmosphere, will produce serious greenhouse effect, if be used for generating, promptly protected environment, to benefit the nation and the people again, its cost is moderate, therefore is used widely.
The biogas power generation technology of domestic utilization, the general float cover type gas holder that all will build big volume utilizes the method that increases the weight of that the pressure of biogas is controlled, and the pressure of whole system is constant, the suction pressure that guarantees methane fuelled engine is stable, and then guarantees the efficient and the power of motor.But there are following three defectives in this scheme:
(1). need the gas holder of a very big volume, be generally 300m
3More than, floor space and cost are all very high, and have unsafe factor;
(2). the float cover type pressure regulation is the fixed value pressure regulation, and pressure is in case determine that be difficult to change, and precision is low, methane fuelled engine is very low to the pressure requirement of biogas, generally at 2.0～4.0KPa, is difficult to realize accurate control in the mode that increases the weight of;
(3). the composition of biogas changes incomplete combustion or the excessive burning that causes machine.This mainly is because the biogas composition difference of different regions; The mode of production difference of biogas also can cause its composition different; Even the biogas that perhaps same biomass pool produces at Various Seasonal, different time, its composition is also inequality; Even among one day, its composition also changes.And under constant pressure, air inflow is stable, promptly under the pressure of setting, the supply of the biogas that acts as a fuel is a definite value, because air inlet amount (being the oxygen air inflow) is constant, when the content of methane in fuel changes, causes the proportions of ingredients of methane and oxygen to change, and then cause the machine acting to change, but the load of machine carrying does not have change.Therefore, the methane content height is the oxygen supply deficiency then, and it is incomplete to burn, and excessive methane just is not discharged from through burning, and what have burns in outlet pipe, " blowing out " phenomenon promptly occurs, simultaneously, may contain a large amount of methane in the exhausting air; On the contrary, the methane content deficiency of doing work at least is with not dynamic load, and machine fluctuates, and make the fluctuation of service of motor, and delivery temperature is too high, also can influence the efficient and the working life of machine.
(4). existing marsh gas power generation engineering, efficient is generally lower.Calculate with the generated energy of per unit volume biogas, in the at present domestic biogas engineering, be generally 1.5～1.8 degree/every cubic metre.
Abroad, technology with American-European developed country is representative, and it adopts Digital Technique that the air inflow of biogas generator is regulated, and controls the ratio of biogas and air better, the efficient of machine is greatly improved, present generated energy can reach 1.8～2.2 the degree/every cubic metre.But this control technique is very high to the requirement of machine, the more important thing is to cost an arm and a leg, and the price of a cover controller is also higher than a motor.Particularly to the small-power unit, the price of a cover control system is higher than the price of machine itself far away.Simultaneously, this controlling schemes is only controlled the air inlet of machine, to having relatively high expectations of source of the gas, need the suction pressure and all stable air supply system of flow of auxiliary construction biogas again, in fact, but also want the gas storage system of the voltage stabilizing of supporting big volume, increased operating cost greatly.
