Description
Technical field
The present invention relates to motor, is a kind of outer combustion-ing engine and working principle thereof.
Background technique
Motor generally refers to heat engine, is a kind of by fuel, or other energy conversion heat energy that is working medium heat energy is further converted to a kind of device of mechanical energy output.
Along with socio-economic development, the mankind constantly increase power and electricity needs, but the exhausted and burning of fossil energy utilizes the environmental pollution that fossil energy causes to bring huge negative effect to society.Seek a kind of new efficient environmental-protection engine and can utilize various energy resources form such as gas, liquid, the many heat-source engines of many fuel of the solid form energy, renewable energy sources (solar energy, living beings, geothermal power etc.) are important means that solves at present energy source and power problem.
Internal-combustion engine is a kind of traditional, utilizes motor very widely.As its name suggests, internal-combustion engine is that a kind of fuel burns in cylinder interior, and modal is petrol engine and diesel engine.Because fuel combustion is carried out under the restrictive conditions such as short time, intermittent type, cause fuel combustion insufficient, tail gas pollution is serious, off-design efficiency is poor, engine scuffing, and maintenance cost is high, high to fuel mass requirement, many shortcomings such as detonation and noise vibration.Internal-combustion engine is a kind of very ripe technology relatively at present, but its development is subject to certain limitation owing to being subject to above-mentioned disadvantages affect.
External-combustion engine is also a kind of ancient motor, common are Stirling engine.This motor is that the pastor Robert Stirling in London invented in 1816, is named as " Stirling engine " (Stirling engine).Stirling engine is unique heat engine, because its theoretic efficiency is no better than intrinsic peak efficiency (Carnot's cycle efficiency, Fig. 5 is the tephigram of Carnot's cycle, the efficiency upper limit of starting in theory function to reach, there is isentropic Compression process 1-2, decalescence process 2-3, isentropic expansion process 3-4 and isothermal exothermic process 4-1 form).Fig. 3 is existing Stirling-electric hybrid structure principle chart.Fig. 4 is the tephigram of desirable Stirling-electric hybrid circulation, by isothermal exothermic process 1-2, waits and holds backheat exothermic process 2-3, and decalescence process 3-4, and wait and hold backheat endothermic process composition.Stirling-electric hybrid is a kind of external-burning engine, and in the firing chamber of fuel outside working medium active chamber, burning continuously, passes to heat by heat exchanger the working medium of engine interior.Stirling circulation is a kind of closed cycle, can select air, hydrogen and helium etc. as internal working medium.
External-combustion engine is that with respect to outstanding advantages of internal-combustion engine it can utilize pluralities of fuel and various heating sources, and such as gas, liquid, solid fuel, the lower fuel ratio of calorific value is as biogas, living beings, complicated component fuels such as coal charcoal.Because external-combustion engine can utilize continuously, burning can improve combustion efficiency by full combustion of fuel for a long time, greatly reduces pollutant emission.Also utilize the thermals source such as solar energy, geothermal power, nuclear energy and some industrial waste heats, can also be used in some special devices, such as submarine and space power equipment etc.
Except motor being divided into internal-combustion engine and external-combustion engine, can also be divided into Reciprocating engine and rotary engine according to engine interior motion mode.Petrol engine above-mentioned, diesel engine and Stirling-electric hybrid are all to belong to Reciprocating engine, and its major character is piston, air cylinder structure.In rotary engine, conventional gas turbine and steam turbine.Fig. 6 is the tephigram of existing gas turbine cycle, has isentropic Compression process 1-2, isobaric heat absorption process 2-3, isentropic expansion process 3-4 and isobaric exothermic process 4-1 form, respectively corresponding air, through gas compressor compression, enters combustion chambers burn, then enters turbo machine and this Four processes of exhaust.High-temperature fuel gas does work to turbo machine while expanding, and externally exports mechanical work.Steam turbine needs the equipment such as the turbo machine, vapour condenser, boiler of larger volume, and volume expands, and is generally used for powerful thermal power plant.Therefore, the application area of gas turbine is wider.
As mentioned above, the burning of gas turbine is to carry out at engine interior, and products of combustion enters turbo machine, therefore from broadly also belonging to internal combustion engine, but due to its rotary movement, makes flowing continuously of air-flow, and then makes combustion process more complete.But because it still belongs to the mode of internal combustion, higher equally to the requirement of fuel.Therefore the concept of external-burning type gas turbine has been proposed very early.20th century the fifties, Donaid L. etc. is just studied coal-fired external-burning type gas turbine.The thermodynamic cycle process of external-burning type gas turbine: air is through compressor compresses, enter the hot device of high temperature heat exchange and fuel and carry out heat exchange at the high-temperature fuel gas of firing chamber discharge, after absorbing heat, become High Temperature High Pressure air, High Temperature High Pressure air enters the turbo machine acting of expanding, after expanding, pressure is barometric pressure substantially, the air of discharging from turbo machine enters firing chamber, burn with fuel mix, form high-temperature fuel gas, and enter high-temperature heat-exchanging, carry out heat exchange with the pressurized air coming from compressor, heat is transferred to pressurized air, self reduces temperature, last waste gas is discharged.Its cycle specificity be working medium through overcompression, backheat,, just through burning, is a kind of thermodynamic cycle mode that utilizes tail part exhaust to burn again after expanding.Fig. 7 is the tephigram of existing external-burning type gas turbine cycle, has isentropic Compression process 1-2, isobaric heat absorption process 2-3, isentropic expansion process 3-4, and isobaric heating process 4-5 and isobaric exothermic process 5-1 composition.
Due to the cycle specificity of gas turbine, determined if there is the high thermal efficiency, working medium to be heated to very high-temperature, conventionally reached more than 1,000 degrees Celsius, therefore very high to the requirement of engine material, manufacturing process is more complicated.In addition after gas turbine design power diminishes (when as purposes such as automobile-used, distributed energies), due to reasons such as some flow losses increasings, makes its efficiency lower.
Summary of the invention

This outer combustion-ing engine comprises compression cooling segment, heating dilation, regenerator and burner, its structure outline is that described compression cooling segment comprises at least two double acting compressors that connect with series connection form, be the suction port of one-level double acting compressor after the relief opening of previous stage double acting compressor connects, and on the path between adjacent two double acting compressors, arrange cooler in order to cooling from previous stage double acting compressor relief opening pressurized air out; Described dilation comprises at least two double-acting expansion machines that connect with series connection form, the relief opening that is previous stage double-acting expansion machine connects the suction port of rear one-level double-acting expansion machine, and before the suction port of every double-acting expansion machine, connects heater in order to heat the pressurized air that enters double-acting expansion machine suction port; Described in afterbody, between the cold fluid side entrance of double acting compressor relief opening and heater before double-acting expansion machine described in the first order, be connected regenerator and in order to heating, enter the pressurized air of heater; The thermal source of described heater is provided by the high-temperature fuel gas of described burner, and the high-temperature fuel gas of flowing through after heater is further for described regenerator provides thermal source, and the combustion gas after regenerator is discharged by engine exhaust port; Described burner inlet communicates with the relief opening of double-acting expansion machine described in afterbody, and the fuel of burner is inputted by outside.
The linkage structure of said burner, heater, regenerator has following several scheme:
Scheme one: described in each, burner is to be connected with series connection form with heater, regenerator, mutually connecting successively with the hot fluid lateral line of heaters at different levels from described burner outlet, be connected with the hot fluid lateral line of regenerator, the hot fluid lateral line outlet of regenerator communicates with external pressure by engine exhaust port again.
Scheme two: described burner quantity is increased to and heater as much, burner is connected with the pipeline on heater hot-fluid side, before each heater, connect a burner, the entrance of the burner connecting before one-level heater after previous stage heater hot fluid lateral line outlet access, the entrance of the hot fluid lateral line of described rear one-level heater connects this grade of burner outlet that heater is corresponding, and the outlet of the hot fluid lateral line of afterbody heater communicates with the hot fluid lateral line of described regenerator.
Scheme three: in parallel between hot fluid lateral line of heater described in each, be connected in series with burner, regenerator again, be that burner outlet pipeline is divided into the hot fluid side entrance that branch road accesses respectively heaters at different levels, the hot fluid lateral line outlet of heaters at different levels accesses the hot fluid lateral line entrance of regenerator again.
The basic principle of this outer combustion-ing engine work is, from extraneous suck, air is through double acting compressor compression, between two adjacent double acting compressors, be provided with cooler cooling, from final stage double acting compressor pressurized air out enter regenerator and with the high-temperature fuel gas heat exchange of discharging from heater, from regenerator pressurized air out enter heater and with the high-temperature fuel gas heat exchange out from firing chamber, pressurized air enters double-acting expansion machine expansion acting, air working medium enters burner and produces high-temperature fuel gas with the fuel mix burning that enters burner from afterbody double-acting expansion machine is discharged, high-temperature fuel gas enters the pressurized air heat exchange on each heater hot-fluid side and cold flow side, from heater combustion gas out enter regenerator hot-fluid side with from the pressurized air heat exchange out of final stage double acting compressor, motor is discharged in last combustion gas.
The temperature difference in the time of can effectively reducing the heat release of engine low temperature end and temperature end heat absorption by cooling in the middle of employing multistage compression and the middle heating of multistage expansion, has reduced system entropy and has produced, the efficiency of raising system.In addition the centre in compression process is cooling can less this process China and foreign countries bound pair gas work.This means and can reduce the temperature (can reduce the use of refractory alloy, reduce costs) of working medium and ensure the higher thermal efficiency.This series connection form is different from the outer combustion-ing engine parallel connection of a plurality of simple single stage compression being expanded and having heat recovery process, after in parallel, each external-burning type heat engine needs a regenerator separately, but whole motor only needs a regenerator herein, reduced engine structure, alleviate weight, saved material.In addition, from the thermodynamic cycle of thermodynamic cycle angle outer combustion-ing engine of the present invention, there is essential distinction with the thermodynamic cycle that simple single stage compression expansion has the outer combustion-ing engine of heat recovery process.
The Double-action reciprocating formula compressor adopting in the present invention and Double-action reciprocating formula decompressor have piston-cylinder assembly.So-called two-way ram-air cylinder structure refers to, cylinder is divided into upper and lower two cylinder spaces by piston, when piston stroking upward with descending time, has working medium in upper and lower two cylinders, can complete effective working procedure.Single action piston-air cylinder structure just can only complete descending and up two strokes at piston and just complete pressure of inspiration(Pi) compression process or expansion exhaust process.In the present invention, use two-way ram-air cylinder structure not only can improve specific power, also has an important function exactly by merging and be connected to heat exchanger (cooler from double-acting cylinder two ends gas exhaust piping, regenerator and heater) and burner, when descent of piston with up time, there is air-flow to flow out, can heat exchanger and firing chamber a quasi-continuous air-flow is provided, strengthened heat transfer effect, and the continuity of burning.Single-acting cylinder is in crankshaft rotating in the time of one week, only have piston stroking upward or have when descending working medium to enter cylinder or discharge cylinder, air-flow is intermittent, has half the time to stagnate with overdraught, and this heat exchanger heat transfer effect and combustion chambers burn have very large adverse effect.Therefore the present invention adopts double-acting cylinder to preferably resolve this problem, has strengthened the heat transfer effect of heat exchanger, makes the air-flow of firing chamber continuous as far as possible, burns more complete, has avoided the drawback of the external-burning engine of single-acting cylinder form.Respectively there are suction port and relief opening in the two ends of double-acting cylinder, control the turnover of air-flow by valve.The time of valve switch can be controlled according to the cam structure of traditional internal-combustion engine.The straight line motion of piston rod can transfer the output that rotatablely moves to by brace and connecting rod framework or oblique disk structure, facilitates later use.
In the present invention, adopt the combustion process after exhaust, due to lower from decompressor air pressure out, but temperature is still very high, this exhaust is passed into firing chamber, and fuel mix, improved the initial temperature of combustion process, can be so that fuel quantity reduces, burn more abundant, reduce partial combustion pollutant.Can coordinate heater number in addition, a burner is set before high-temperature fuel gas enters each heater, is about to original fuel and is assigned in each burner, burn with incoming flow combustion gas mixing, improve fuel gas temperature, in entering heater, add the pressurized air of hot-cold fluid side.Due to the fuel quantity minimizing of each burner, the combustion temperature in each burner is reduced, reduce the discharge of nitrogen oxide NOx, and also reduced the high temperature that combustor material bears, can select more cheap material, reduce costs.
The power adjustments of outer combustion-ing engine of the present invention can need to regulate the size of air inlet according to the power of motor by set up an air valve at suction port.Fuel valve is controlled the size of fuel inlet, and coordinates the size of air inflow, guarantees the heat input that motor is required.
The present invention than the advantage of prior art is:
Compare with traditional combustion engine, have higher efficiency of thermal cycle and specific power; Long service life, owing to directly acting on cylinder unlike internal-combustion engine hot flame, on piston and air valve, these component lifes are longer, adopt external-burning type burning to avoid the adverse effects such as pinking, carbon deposit, moving element only contacts with clean air, also makes the moving element life-span increase; Stable outer cylinder burning makes can fully burning of fuel, reduces pollutant emission, and engine noise and vibration are little; Can use pluralities of fuel, gas, liquid, solid, living beings and biogas etc.; Further improve the form of intermediate heater, can utilize solar energy, nuclear energy, geothermal power and other thermals source that is easy to obtain to produce mechanical energy.
