Description
【Technical field】
The present invention relates to a kind of energy conversion power plant more particularly to it is a kind of by gas pressure can and thermal energy be converted into
The application of the power plant of mechanical energy and the device and the method for promoting energy conversion efficiency.
【Background technology】
It is understood that thermal energy is directly translated into there are many power plants of mechanical energy.Such as：Internal combustion engine, external-combustion engine, vapour
Turbine, aero-engine, rocket engine, missile propulsive plant etc..
For current thermal power reforming unit, major defect is：Exhaust temperature is high, fuel effective rate of utilization
Low, volume is big and heavy, and specific power is not high.Such as：By the internal combustion engine of working medium expanded by heating acting, there are three types of bases for hot merit conversion
This cycle.1. dual cycle；2. constant volume heat cycles；3. level pressure heat cycles.Since thermal cycle expansion is not thorough, or
Residual temperature is relatively high, and exhaust heat is relatively more (engine exhaust gas takes away the heat of 30 ﹪ or more).And the knot of transformation mechanism
Structure is (such as：Toggle) volume is bigger and heavy.So that the specific power difficulty of power plant gets a promotion.Although aviation is sent out
Motivation, rocket engine, missile propulsive plant specific power is bigger, and the propulsive efficiency in order to promote engine need to improve the temperature of combustion gas
Degree and pressure.But the leaving velocity residual temperature of tail gas is also high, and the thermal energy of fuel is made not efficiently used fully.In addition by temperature and pressure
Power influences, and the elevated temperature strength promotion of material is limited.
To solve the above-mentioned problems, there has been proposed pinking formula energy transformation power devices.Such as：Russia's liquid pulse detonation
Engine specialized laboratory, the academy of sciences of Russia Novosibirsk pressgang connect season Prokofiev fluid dynamics research Moscow aeronautics in one's power
Institute etc. studies successful pulse-knocking (being exactly to explode in mechanism) aero-engine for 2016.Exactly pushed away using Fuel explosion generation
The aero-engine of power, the common compressor burning of thermal efficiency ratio is one times high.Explosion and the essential distinction burnt are：Occur
Explosion the time required to most it is short can microsecond, and burn generally in signa or so.Explosion will produce prodigious wink
Between pressure and temperature, can make thermal energy be converted into greatest extent gas molecule flowing kinetic energy.In explosion generating process generally not
Controllable, and shake bigger with noise.So in practical applications must be controlling these factors.
Explosion is divided into physical explosion and chemical explosion.Physical explosion is due to colliding, the explosion that the reasons such as pressure is excessive generate,
Chemical explosion is since chemical reaction generates the explosion that huge energy generates.And the explosive effect described in us is exactly energy at certain
Assemble in one closed local cell domain and increases, when reaching a certain pressure threshold value, energy discharges suddenly within the extremely short time,
Explosive effect is generated, just as the explosion suddenly of high pressure balloon.Experiments have shown that in the feelings of the temperature and pressure without improving gas
Under condition, explosive effect can make the thermal energy of gas or pressure energy be converted into the kinetic energy of gas molecule flowing to the greatest extent, therefore go out
The phenomenon that existing gas temperature significantly declines.The microscopic explanation of explosive effect is：When occur explosion time, institute's closed container (or
It is relatively closed) the powerful warm-up movement potential energy that occurs in moment of inner gas molecule, intermolecular potential energy effect is lower as being collected
Equally, in synchronization, same behavior, integrating action concentrates on the ordering behavior of a certain result to body " consciousness ", occurs all
The phenomenon that energy (molecule thermal energy, molecular potential etc.) is all concentrated to this result (kinetic energy that gas molecule flows), therefore occur
The phenomenon that gas molecule temperature (thermal energy) declines to a great extent.
And mechanical energy can easily be just converted into the way of impact high speed impeller by the kinetic energy of gas molecule flowing
, therefore can improve thermal energy using explosive effect or pressure energy is converted into the transformation efficiency of mechanical energy.Secondly explosive effect energy
Great instantaneous power is generated, controlling the frequency of explosion can make power plant obtain larger specific power.
In order to ensure the lasting generation of explosive effect and have continuity, it is necessary to there is a structure that can be iteratively produced unexpected " rupture "
It releases energy, and " healing " energy can be closed at once, and the repeating work of control can be facilitated.Generally balloon burst, cut
It can not just heal automatically again.And the technological difficulties for duration control effect of exploding at present are exactly the automatic healing after cut.
I.e. explode before gas constrained by closed container, once explosion after restraining force moment be reduced to zero, in this way energy quick release of energy
Again it is clear-cut thoroughly, while minimizing (namely pressure) cut could heal automatically at the end of energy discharge, and reformulation is closed
Space, however current valve can not accomplish this point.
