Technical field
The invention provides a kind of Stirling thermal engine operating taking air or hydrogen or cold-producing medium as working medium. This Stirling thermal engine operating comprises expansionThe critical pieces such as machine, engine, cylinder, airtight container. This Stirling thermal engine operating can utilize environment atmospheric pressure acting, because ofAnd its output work and efficiency are all high than conventional heat engine.
Background technology
We know, conventional heat engine relatively consumes energy, and the whole world is faced with day by day exhausted problem of global warming, fossil fuel, normalRule Stirling thermal engine operating can not utilize environment atmospheric pressure acting.
Summary of the invention
In order to address the above problem, the invention provides a kind of Stirling thermal engine operating that can utilize environment atmospheric pressure acting. This heatMachine comprises two or many isothermal heat release compressed action cylinders, decompressor or double-acting cylinder, triple valve or multiple-way valves, heat exchange systemThe critical pieces such as system, airtight container, and utilize pressure in sealed container acting.
Thermodynamic cycle is similar to Stirling circulation, Stirling circulation by isothermal heat release compression, etc. hold that heat absorption heats up, decalescenceExpand, etc. put the heat Four processes composition such as cooling.
Power take-off mechanism when isothermal heat release compressed action cylinder is working medium isothermal heat release compression. Piston can be in cylinder back and forthMobile, each cylinder has inlet valve and exhaust steam valve, and inlet valve and exhaust steam valve are arranged on cylinder bottom, and inlet valve connects decompressorOr double-acting cylinder outlet, exhaust steam valve connects decompressor or double-acting cylinder import, and correspondingly, triple valve or multiple-way valve are arranged onThe export and import of decompressor or double-acting cylinder. These cylinders are arranged in airtight container, are full of pressure-air in airtight container,The outlet pressure of decompressor or double-acting cylinder is more than or equal to pressure in sealed container. These cylinders absorb heat by heat-exchange system orHeat release.
Power take-off mechanism when decompressor or double-acting cylinder are working medium isothermal expansion.
The working medium of HTHP is decalescence expansion process while flowing through decompressor or double-acting cylinder, the working medium decompressor or two of flowing throughAfter active cylinder, reduce,
Working medium enters an isothermal heat release compressed action cylinder after leaving decompressor or double-acting cylinder. When beginning, inlet valve and rowSteam valve is closed, and piston is in cylinder bottom. When work, inlet valve is opened, because of pressure in sealed container be less than or equal to decompressor orDouble-acting cylinder outlet pressure, piston will move to cylinder head, and this process is similar to the intake stroke of Otto cycle heat engine.In the time that piston moves to cylinder head, piston is fixed on to cylinder head, close inlet valve, close after inlet valve, from decompressorOr double-acting cylinder working medium out enters other isothermal heat release compressed action cylinder, open heat-exchange system valve, utilize water-cooledBut this cylinder, this process is to wait to put hot cooling procedure, and liberated heat is passed to another isothermal heat release compressed action cylinder.
In the time that in this cylinder, Temperature of Working equals environment temperature, unclamp piston, close heat-exchange system valve, start cooling fan,Make this cylinder make isotherm compression exothermic process, the cooling fan of also can stopping using, makes this cylinder make adiabatic compression process. Because in cylinderPressure is lower than pressure in sealed container, and pressure in sealed container will be oppressed piston and be moved to cylinder bottom, pressure in sealed containerTo piston acting, piston driving engine operation, pressure in sealed container acting can be utilized by heat engine and export.
In the time that inner pressure of air cylinder equals pressure in sealed container, close cooling fan, open heat-exchange system valve, absorb another etc.Temperature heat release compressed action cylinder etc. puts hot cooling procedure liberated heat, and this process is to wait to hold heat absorption temperature-rise period.
In the time that Temperature of Working is elevated to heat source temperature, open the exhaust steam valve of isothermal heat release compressed action cylinder, working medium enters decompressorOr double-acting cylinder, working medium absorbs thermal source heat and makes decalescence expansion acting process. In the time that piston piston moves to cylinder bottom,Exhaust steam valve cuts out, and completes whole circulation.
Detailed description of the invention
Introduce a specific embodiment below, detailed description of the invention is not limited to this example.
If the operation temperature area of heat engine is 300K～600K, working medium is air, and operating pressure is: high pressure (expander inlet pressure) 0.404MPa, low pressure (wait and put the rear pressure of heat) 0.105MPa, is full of air in airtight container, and pressure is 0.202MPa.
Working medium pressure in the time of expander inlet is 0.404MPa, and temperature is 600K, and working medium is that decalescence is swollen while flowing through decompressorSwollen process, the working medium pressure after decompressor of flowing through is reduced to 0.21MPa, and temperature is 600K.
Working medium enters an isothermal heat release compressed action cylinder after leaving decompressor. Cylinder is arranged in airtight container, inlet valve andExhaust steam valve is arranged on cylinder bottom, and when beginning, inlet valve and exhaust steam valve are closed, and piston is in cylinder bottom. When work, inlet valveOpen, because pressure in sealed container 0.202MPa is less than outlet pressure of expansion machine 0.21MPa, piston will move to cylinder topPortion, in the time that piston moves to cylinder head, is fixed on cylinder head piston, closes inlet valve, opens heat-exchange system valve,Utilize this cylinder of water cooling, this process is to wait to put hot cooling procedure, and liberated heat is passed to another cylinder.
Because this process is to wait to put hot cooling procedure, in the time that in this cylinder, Temperature of Working equals environment temperature 300K, in cylinder, pressPower will be reduced to 0.105MPa.
In the time that in this cylinder, Temperature of Working equals environment temperature, unclamp piston, close heat-exchange system valve, start cooling fan,Make this cylinder make isotherm compression exothermic process. Because inner pressure of air cylinder 0.105MPa is lower than pressure in sealed container 0.202MPa,Pressure in sealed container will be oppressed piston and be moved to cylinder bottom, piston driving engine operation, pressure in sealed container actingCan be utilized by heat engine and export.
Tradition stirling cycle heat machine need to consume decalescence expansion process working medium and do work isotherm compression exothermic process, passesThe output work of system stirling cycle heat machine will be less than the acting of system decalescence expansion process working medium; And heat engine is utilized airtight containerInternal pressure has been done work isotherm compression exothermic process, need not consume decalescence expansion process working medium and do work isotherm compressionExothermic process, and pressure in sealed container acting can utilize by heat engine and export, and therefore the output work of heat engine will be far awayBe greater than the output work of traditional stirling cycle heat machine under identical operating mode.
In the time that inner pressure of air cylinder equals pressure in sealed container 0.202MPa, close cooling fan, open heat-exchange system valve, inhaleReceive another cylinder etc. and put hot cooling procedure liberated heat, this process is to wait to hold heat absorption temperature-rise period, and Temperature of Working will raiseTo 600K, pressure is elevated to 0.404MPa.
In the time that Temperature of Working is elevated to 600K, open exhaust steam valve, working medium enters decompressor absorption thermal source heat and does decalescence expansionActing process. In the time that piston piston moves to cylinder bottom, exhaust steam valve cuts out, and completes whole circulation.
