Description
Technical field
The utility model belongs to biogas energy transformation technology field, relates in particular to a kind of household biogas electricity generating device.
Background technique
At present, the used biogas internal-combustion engine of marsh gas power generation is mainly two classes, i.e. double fuel formula and clean burn formula.
(1) double fuel formula internal-combustion engine adopts diesel oil+biogas double fuel, carries out work by combustion by a spot of diesel oil of compression ignite to light biogas.The characteristics of this internal-combustion engine are can regulate diesel oil and biogas fuel ratio, and are not enough even when stopping the supple of gas or steam when biogas, and motor still can proper functioning, and power does not generally wait at tens kilowatts to up to a hundred kilowatts.Adopting diesel oil ignited biogas one diesel dual-fuel internal-combustion engine is to solve the slow effective way of biogas velocity of combustion really.Its shortcoming is system complex, must have fuel feeding and air feed two covering devices simultaneously; Because fuel injection quantity is less, diesel oil is not obvious to the cooling action of oil nozzle, makes the heat load problem of oil nozzle more serious, has influenced the life-span of oil nozzle.Must adopt the speed control system of the electronic governing system transformation of the way in addition,, increase cost greatly, not be suitable for the marsh gas power generation of decentralized peasant household to adapt to the adjusting of operating conditions to two kinds of fuel.
(2) and the clean burn formula adopts the Spark ignition type petrol engine, clean burn biogas, general power is less, has only about 3-5 kilowatt, and its transformation of the way characteristics are simple in structure, and are easy to operate, and need not auxiliary fuel.
And external most small-sized methane generator forms by former gasoline engine refitting, and diesel engine refitted becomes low power biogas machine seldom, and reason is that its control system all adopts electronic governing system to control mixer, has increased cost.And at home, the repacking of most of small-power biogas machines is all based on diesel engine, mainly more high-power such as 10kW, 20kW, 50kW research and develop the aspect, but technically also have certain defective, do not obtain large-scale popularization and use.As: what the internal combustion engine start mode adopted is hand pull starting-up.But this Starting mode is required great effort very much, moreover starts several times sometimes in one day, bothers very much bad operation.Simultaneously, most of double fuel methane fuelled engines of domestic research and development are generally just carried out repacking than shallow hierarchy to diesel engine and petrol engine, thermal property research to motor is not dark, because it is few to contain methane content in the biogas, engine displacement is constant, can not increase heat vale of mixture, the thermal efficiency low due to its generated output rate of descent reach 20%～30%.
The model utility content
The purpose of this utility model is to provide the household biogas electricity generating device that a kind of cost is low, startup is fast, generating efficiency is high.
For solving the problems of the technologies described above, household biogas electricity generating device of the present utility model, it comprises gas mixer and the explosive motor that connects by pipeline, also comprises the gas boosting storage device that is connected by pipeline with gas mixer, the explosive motor generator that is in transmission connection.
Described gas boosting storage device comprises pressurization gas holder and the pressure regulation gas holder that connects by pipeline, the air outlet of pressure regulation gas holder is connected by pipeline with the biogas suction port of gas mixer, pipeline between pressurization gas holder and the pressure regulation gas holder is provided with electromagnetic valve of gas circuit, and the pressure regulation built in gas tank has pressure regulator valve.
The biogas suction port place of described gas mixer is provided with the interruption steam supply valve, and the air inlet place is provided with air-strainer.
Described generator also is connected with starting electrical machinery.
Be connected with the generator voltage stabilizer on the described generator.
Described pressurization gas holder is provided with balancing weight.
Adopt technique scheme, store by the pressurization of gas boosting storage device to biogas, save spatial volume, biogas and air mixing reach best combustion ratio then, enter explosive motor and light acting, drive generator and generate electricity; The pressurization gas holder is brought up to 10KPa with biogas pressure, and electromagnetic valve of gas circuit plays a part the gas circuit conducting and ends, and pressure regulator valve plays the effect of adjusting the biogas pressure of stablizing the pressure regulation gas holder; The interruption steam supply valve plays the effect to the interval air feed of gas mixer, and air-strainer can filter airborne impurity, makes the central air cleaning of mixed gas; Use starting electrical machinery, can be convenient, start rapidly; The generator voltage stabilizer plays the effect to the generating voltage stabilizing; Balancing weight can be regulated the gas storage pressure of pressurization gas holder; The utility model is controlled engine gas gas supplied pressure and flow by the automatic control supervisory device after startup, primary voltage and power load situation are sent in control simultaneously, its advanced technology, volume is little, in light weight, compact structure, be convenient to transportation and installation, start rapidly, easy to operate, easy to maintenance, safe and reliable, less demanding to combustion gas, the biogas that domestic methane tank produces promptly can be used as the source of the gas of internal-combustion engine through simple process, the generating efficiency height, not only can use by separate unit, also can several All-China Federation of Taiwan Compatriots close power supply, invest little, benefit is big, common peasant household can both afford to consume.
