Description
Technical field
The utility model belongs to negative pressure power equipment field, especially utilize high-temperature gas, internal-combustion engine hot gas or the tail gas of solar energy, underground heat, inflammable matter burning generation, the heat energy such as high-temperature gas that factory discharges to import cylinder, utilize the heat radiation of high temperature media gas in cylinder and cylinder outside to form temperature difference, make enclosed cylinder produce negative pressure and thermal power transfer is become to the power equipment of kinetic energy.
Background technique
Traditional power equipment has steamer, internal-combustion engine, external-combustion engine.
Steamer: be unable to do without boiler, whole device is heaviness but also huge not only; The pressure and temperature of initial steam can not be too high, and exhaust pressure can not be too low, and the thermal efficiency is difficult to improve; It is a kind of reciprocator, inertia confinement the raising of rotating speed; Working procedure is discontinuous, and the flow of steam is restricted, and has also just limited the raising of power.
Internal-combustion engine: complex structure, higher to demanded fuel, the cleanliness of fuel is required strictly to environmental pollution.
External-combustion engine, if Stirling engine is wherein a kind of, Stirling engine and internal-combustion engine relatively possess following advantage:
Be applicable to the various energy, no matter be liquid, gaseous state or solid-state fuel, when adopting heat-carrying system (as heat pipe) indirect heating, almost can use any high temperature heat source (solar energy radioisotope and nuclear reaction etc.), and motor itself (except heater) does not need to do any change.Stirling engine, without compressor boost, uses general blower fan to meet the demands, and allows fuel to have higher impurity content simultaneously; Stirling engine single-machine capacity is little, and unit capacity is from 20-50kw, the increase and decrease power system capacity that can suit measures to local conditions; Simple in structure, number of components is fewer 40% than internal-combustion engine, and room for price-cut is large; Maintenance cost is low.
Stirling engine is when operation, due to continuous burning in the firing chamber of fuel outside cylinder, the working medium that is independent of combustion gas is absorbed heat by heater, and press Stirling circulation and externally do work, therefore avoid pinking acting and the intermittent combustion process of similar internal-combustion engine, thereby realized efficient, low noise and low emission operation.Efficient: overall energetic efficiency reaches more than 80%; Low noise: at the bottom of 1 meter of bare machine noise in 68dBA; Low emission: exhaust emissions reaches Europe 5 standards.
Because working medium is not burnt, external-combustion engine has been avoided the quick-fried acting problem of the shake of traditional combustion engine, thereby has realized high efficiency, low noise, low pollution and low operating cost.The external-combustion engine various inflammable gass that can burn, as rock gas, biogas, petroleum gas, hydrogen, coal gas etc., the also liquid fuel such as incendivity diesel oil, liquefied petroleum gas (LPG), can also burn wood, and utilizes solar energy etc.As long as hot chamber reaches 700 ℃, the equipment operation of can doing work, ambient temperature is lower, and generating efficiency is higher.The advantage of external-combustion engine maximum is to exert oneself not affected by altitude with efficiency, is very suitable for high altitude localities and uses.
Simultaneously Stirling engine remain subject matter and shortcoming be: manufacture cost is higher, and working medium sealing technique is more difficult, and reliability and the life-span of Sealing also have problems, and cost of material is high, and power adjustments control system is more complicated, and machine is comparatively heavy; The cost of expansion chamber, pressing chamber, heater, cooling chamber, regenerator etc. is high, and heat loss is 2-3 times of explosive motor etc.
Organic rankine cycle system comprises pump, vaporizer, decompressor, generator, condenser etc.Heat collector absorbs solar irradiance, and in heat collector, heat exchange medium temperature raises, and heat transferring medium is passed to organic working medium by vaporizer heat.Organic working medium is level pressure heating in vaporizer, and the gaseous state organic working medium of high pressure enters decompressor expansion acting, drives generator generating; The organic working medium that decompressor afterbody is discharged enters level pressure condensation in condenser, and the organic working medium of condensator outlet enters vaporizer and completes power generation cycle one time after pump pressurization.
Organic rankine cycle system exists conversion efficiency not high, and volume is large, need to be by baroque decompressor acting.
Pancake engine, engine piston is evenly distributed in bent axle both sides, in the horizontal direction side-to-side movement.Make whole height reduction, the shorten length of motor, the center of gravity of car load reduces, Vehicle Driving Cycle is more steady, motor is arranged on the center line of car load, the moment that both sides piston produces is cancelled out each other, greatly reduce vehicle vibration under steam, engine speed is greatly improved, reduces noise.
The great advantage of pancake engine is that center of gravity is low.Because its cylinder is " keeping flat ", not only reduced the center of gravity of automobile, can also allow headstock design not only flat but also lowly, these factors can strengthen the riding stability of automobile.Meanwhile, the cylinder arrangements of horizontal opposition type is a kind of symmetrical rock-steady structure, and this makes the running smoothness of motor better than V-type engine, and power loss during operation is also minimum.Certainly it is better handling that lower center of gravity and balanced distribution have been also vehicle band.Centre of gravity: the transverse vibration of generation is easily absorbed, effectively the heavier motor center of gravity of full car reduced by support, more easily reaches whole machine balancing.Low vibration: the balance good (offset 180 degree left and right) of piston movement.Compare in-line arrangement, counterweight factor required aspect bent axle reduces, and helps rotating speed and promotes.It can keep 650 slow-speed of revolution that turn, and guarantees that motor works stably.Compare equally other motor line oil consumption minimum.
Shortcoming is: except because horizontal opposition type structure comparatively complexity, is also difficult to solve just like problems such as oil lubricatings.Horizontal cylinder, because the reason of gravity can make machine oil flow to bottom, makes cylinder on one side can not get lubricated fully.Although Porsche and Subaru have well solved numerous technical barriers, high-precision manufacture requires also to have brought higher maintenance cost, and because body is wider, thereby and is unfavorable for layout.
