Abstract
The utility model belongs to thermoelectric conversion technology. Coal, firewood, methane gas, etc. are used as fuels. According to a working principle of a free piston stirling engine-a straight line generator, the utility model provides electricity for illumination for families and small enterprises and institutions in no-power region, domestic appliances and small electric production tools. The engine-generator set uses a fully sealed structure, and a heat head in the shape of a rotation body shape directly absorbs heat from a combustion furnace. Automatic circulating water is used for cooling a gas cylinder. The combustion furnace can use a civil range or share one stove with other purposes. As the utility model does not use oil to lubricate, the utility model has no need of servicing in the usage period.
Description
The utility model belongs to thermoelectric generation technology.Or rather, being that the heat energy (heat energy that comprises high-temp waste gas, vapour) that fuel combustions such as coal, firewood charcoal, biogas, natural gas produce use free piston stirling engine---linear electric generator is converted into electric energy, lives and the production electricity consumption for areas without electricity family and small-sized enterprise and institution provide.
Existing is the thermoelectric perpetual motion machine of the energy with solar energy, oil, makes satellite and special occasions power supply.What have can not use above-mentioned fuel work, and what have makes working medium owing to pursue high efficiency, small size, employing high pressure hydrogen or helium, complex structure, material expensive, and the manufacturing cost height is unsuitable for civilian.
The purpose of this utility model is to use free piston stirling engine---the operation principle of linear generating unit, and produce and make the energy with civilian conventional fuel, cheap, be suitable for civilian minisize thermoelectric machine.
The utility model adopts thin-walled ball-type or the hot head of other revolution bodily forms, absorbs heat from combustion furnace, drives Stirling engine work.Engine one generating set is the full seal type structure, adopts compressed air or other Compressed Gas to make working medium, and sliding surface adopts the plastic coating oil-free lubrication.All part adopts homemade current material, and is simple in structure, low cost of manufacture.
One of the minisize thermoelectric machine general assembly drawing that accompanying drawing system is advised (not comprising combustion furnace and cooling device), for clearly illustrating that internal structure, the left side is a cutaway view.
The minisize thermoelectric facility have water-cooled cylinder body 3.Gas distribution piston 6 and power piston 4 reciprocating motion therein.Power piston 4 connects linear motor rotor 2.Adopt permanent magnet or self-excitation excitatory.When mover at magnetizing coil 1(or permanent magnet) when moving in the magnetic field that forms, the electric current of generation is drawn outside the machine from terminals 8.Directly stretch into combustion furnace for hot 7, a heat outside can also add extended surface increases caloric receptivity.The engine power generation unit has support 10 to be placed on the combustion furnace.
Combustion furnace can be used Civil energy-saving cooking stove, dedicated combustion furnace or with the shared combustion furnaces of other purposes (kitchen range).
Cooling device is to put a water tank aloft, links to each other with free piston stirling engine one straight line generating set cooling chamber by intake-outlet (5,10), relies on the temperature difference to realize self-loopa.For obtaining favorable cooling effect, also can in system, add a circulating pump, carry out and force cooling.
The present invention is applicable to areas without electricity, sparsely populated for area (particularly mountain area, grassland, desert, island etc.) resident inclined to one side, far away, have inconvenient traffic, away from electrical network, can use the utility model solution illumination and small-sized household electricity device (such as television set, electric fan), productive power device (shear, air blast) electricity consumption. Also be applicable to team's groups such as small mine, geology, exploration, earthquake, archaeology, exploration. To the electricity area is arranged, can be used as miniature emergency power supply.
