Abstract

The invention discloses a gasification and expansion power device of liquid gas. An internal combustion engine is constructed to be a substrate, and the liquid gas is automatically gasified and expanded to push a piston to do work so as to produce kinetic energy in a normal-temperature and normal-pressure cylinder. The device is in an environmentally-friendly and pollution-free energy supply mode, and can replace the conventional power devices which supply energy by burning fossil fuels, such as internal combustion engines, steam engines and the like; and in the energy supply mode, most of fossil fuels can be replaced and the consumption of the fossil fuels can be greatly reduced. The power device mainly has the advantages that: a gasification reaction in a physical reaction is used as the energy supply mode, and a new substance is not produced, so environmental friendliness and pollution freeness are guaranteed; the initial energy of the power device is originated from solar energy; the sun irradiates the earth, and most of heat is absorbed by the atmosphere; and most of energy of the reaction is gasified and expanded to produce kinetic energy when heat in the air is absorbed by the liquid gas at normal temperature higher than a gasification point.

Description

Liquid gas gasification expansion power plant

Technical field

The present invention is a green non-pollution power plant, belongs to the power core of device.May be used on replacing internal-combustion engine or steamer in the mechanical device of motor car engine and various dependence internal-combustion engine or steamer energy supply.

Background technique

The energy and environmental protection two large problems are perplexing the people of the world, and world's main energy sources still is a fossil fuel now, and the rapid minimizing of fossil fuel is also affecting the people of the world's the heart, and each state all taps a new source of energy stepping up; Environmental pollution is human urgent another big problems that solve, and the evil backstage manipulator maximum behind the scenes of environmental pollution now combustion of fossil fuel exhaust gas discharged just.Be not difficult to find out if can find a kind of energy-provision way to replace fossil fuel in conjunction with above two large problems and just can make these two problems obtain to a great extent alleviation.This product produces under this condition just, the industrial revolution initial stage, the mankind invented steamer, utilize boiler to heat water to the gasification expansion and inject cylinder promotion piston motion generation kinetic energy, this device relies on combustion of fossil fuel that primary power is provided, and the water vapour that promotes piston acting generation kinetic energy does not produce pollution, but, wasted 80% energy fully, and volume has been replaced by internal-combustion engine more greatly and finally because the heat energy utilization rate is lower.Internal combustion engine principle and steamer are similar, also be converted into volume expansion and in cylinder, promote piston acting generation kinetic energy with liquid, only steamer is to utilize under the externally energy supply condition of physical reactions " gasification " to make liquid become gas, and internal-combustion engine is by chemical reaction " burning " liquid fuel to be changed into gas, improved place is liquid and gaseous state transforms the place by having transferred in the boiler in the cylinder, improved capacity usage ratio greatly, and boiler has been replaced to fuel tank reduced volume greatly, but what do not change all the time is energy source, still be to rely on the burning of fossil fuel that initial energy is provided, so the consumption and the exhaust gas discharging of fossil fuel never are resolved, progress along with science and technology, the development in the world, a large amount of consumption of the energy and a large amount of dischargings of waste gas have caused energy problem and environmental problem to become international big problem.

Summary of the invention

In view of this situation, through deeply thinking, I find a solution, and that utilizes liquid gas to gasify at normal temperatures and pressures exactly to expand and produces kinetic energy.This design also be accidental inspiration institute extremely, gas can liquefy when low temperature or high pressure or low temperature are held concurrently high pressure and be liquid as you know, and liquid gas annoying gas that turns to when heating up or reduce pressure, the principle of steamer utilization is exactly the gasification expansion acting of liquid, only it is to make its gasification be water vapour by outside heat supply in script water at normal temperatures and pressures, why we can not allow some gases be liquefied as liquid under cryogenic high pressure so, expose with this liquid gas then and make the acting of expanding of its automatic gasifying at normal temperatures and pressures? this mode need not extraneous initiatively energy supply, the energy that it absorbs is that (during the liquid gas gasification is heat absorption to heat energy in air, can take lighter to test), and airborne heat mainly comes from the sun, that is to say that energy source comes from solar energy, in addition owing to need not boiler heat supplying, so the volume aspect also can be suitable with internal-combustion engine, and gasification reaction occurs in the cylinder, capacity usage ratio and indifference with internal-combustion engine, because this reaction is a physical reactions, so do not produce novel substance, therefore can not produce pollution, because this reaction has absorbed airborne heat, also can play certain containment effect in addition to global warming when can the whole world popularizing when using.Suggestion uses liquid gas to be liquid oxygen or liquid nitrogen, and these two kinds of gases reserves in atmosphere are very big, be easy to obtain, and equal uncontamination waste gas.Because of above just my argumentation in theory, power with I people can't be put into practice and test, so aspect details, also have a lot of X factors: first, the source of liquid gas, therefore non-high-grade, precision and advanced science and technology is produced only needs common industrial liquid gas to get final product, the mode of just utilizing air compression to obtain, though how do not know the specific operation step is, but looked into price on the net, the liquid oxygen price that contrasts the homogenous quantities of petrol price discovery now is lower than petrol price now, whether that is to say that liquid oxygen cost in the existing processes manufacturing is lower than gasoline, just not knowing to produce needs to use the combustion of fossil fuel energy supply in the liquid oxygen process.Second, raw material selection aspect, every data show that the selected possibility of liquid oxygen is bigger, liquefaction point is higher, more easily produce, and not only oxygen is not harmful gas, or useful gas, can produce later local pure and fresh oxygen zone among a small circle in reaction, can play very big fresh air effect for the city that a large amount of automobiles are assembled, but disadvantage is that the liquid oxygen chemical property is active, does not know whether can vivaciously produce other problems because of chemical property in course of reaction, as damage equipment etc., but as select for use ceramic heart etc. should avoid this problem; If select the words chemical property of liquid nitrogen to have considered, because liquid nitrogen chemical property and torpescence, what need consideration is exactly the manufacture cost problem.The 3rd, the liquid gas carrying, transportation and can, liquid gas needs airtight carrying, this is thought and easily solve according to now technical merit, so but also can't provide a concrete effectively embodiment owing to can't test me, can ignore as for transportation, suggestion distributes by the area and sets up liquid gas station, just as the gas station, need not to offer the Pipeline Under Mother Earth road, as long as there is compressed air unit can on-the-spotly make liquid gas, the words suggestion replacement method of can, unified " fuel tank " (should be the liquid case) specification, one usefulness, one is standby, uses up replacement, and empty van is taken liquid gas station topping up (if compressed air unit generation noise pollution also is to need to solve certainly).The 4th, equipment improvement, because present patent application is a scheme, do not have concrete in kind, so the device specifics aspect can't provide perfect scheme, only at motor car engine, making blank according to principle should not be problem, but social now development in science and technology is rapid, machinery very becomes more meticulous, only be to make new product again to substitute used equipment be a kind of waste to existing equipment, so if possible still suggestion is done on the existing equipment basis to revise, because this device is still very approaching on working method with internal-combustion engine, only need to change fuel tank, on entrance, carry out airtight measure, be adjusted into low temperature resistant at resistant to elevated temperatures characteristic cylinder, spark plug cancellation etc. gets final product, if this technology can be promoted in the whole world in the future, being users so also can be more acceptant, improve equipment after all and saved big a sum of money than exchange device more, if wanting to strengthen effect can do some such as lay a heat supply in cylinder certainly, liquid gas is injected directly on the thermal source, make little changes such as gasification reaction aggravation.

Embodiment

Liquid gas in one seal container is injected the cylinder trace, because in the cylinder is the normal temperature and pressure state, so this liquid gas can absorb airborne heat and sharply gasification expansion promotion piston acting under normal pressure, then discharge by exhaust port, the liquid gas of reinjecting after piston sets back promotes the piston acting and so forth.
