Description
Technical field
The present invention relates to heat energy and power field, the single thermal source closed circulation of especially a kind of conventional piston motor.
Background technique
According to thermodynamic (al) fundamental law, hot machine must need the thermal source of two different temperatures.In the world all hot machines all be with environment as low-temperature heat source or make certainly be higher than ambient temperature thermal source as low-temperature heat source; And make up the high temperature heat source that temperature is higher than environment through combustion fuel or through solar energy; For this reason, human consumption mass energy, also environment has been caused severe contamination.If can invent a kind of is high temperature heat source with environment as high temperature heat source and/or with low-grade heat source (like seawater, underground heat, tail gas, waste heat of plant and solar thermal collection system etc.); And be lower than the motor of the low-temperature heat source of environment and low-grade heat source temperature through temperature of built-in system structure, will have epoch making significance.
Summary of the invention
Want to utilize environment or low-grade heat source as high temperature heat source; In engine system, make up a low-temperature heat source; Unique method is exactly with the gas that comes from environment, maybe will comes from the gas of low-grade heat source or the gas that will in environment, absorb heat or the gas that will in low-grade heat source, absorb heat carries out adiabatic degree of depth compression or be similar to the adiabatic degree of depth compressing; The pressure and temperature of compressed gas all increases substantially in degree of depth compression process, in by the gas of degree of depth compression, sneaks into liquid (containing threshold state), and liquid and gas take place to conduct heat and is phase-changed into gas; Pressure is raise, temperature slightly raises or do not raise or descend; Carry out the adiabatic expansion work done then, the amount of expansion working is greater than the power consumption of compression process, so the external outputting power of system; Gas temperature when work done is over drops to the temperature that is lower than before compressing, and has so just made up a new low-temperature heat source.If on the surface, this process has been violated thermodynamic (al) law of correlation, but labor; Can know and in high temperature and high pressure gas, sneak into liquid when (containing threshold state); Pressure can significantly raise, and the gas temperature the when rising of pressure can cause expansion working to be over declines to a great extent, and the essence of this process is to have utilized the exchange of mass transport process and diabatic process; Replace diabatic process with mass transport process, thereby realized making up the purpose of low-temperature heat source.
In by the gas of degree of depth compression, sneak into product that the amount of liquid (containing threshold state) should satisfy liquid gasification back gas phase total mole number n, temperature T and gas constant R greater than this product before sneaking into liquid.In by the gas of degree of depth compression, sneaking in the liquid process of (containing threshold state), should keep the constant volume state as far as possible.
In order to address the above problem, the technological scheme that the present invention proposes is following:
The single thermal source closed circulation of a kind of conventional piston motor comprises cylinder and piston, and said piston is arranged in the said cylinder; On the cylinder cap of said cylinder, establish suction port; The place establishes intake valve at said suction port, on the cylinder cap of said cylinder, establishes relief opening, establishes exhaust valve in said exhaust ports; Said suction port and said relief opening are communicated with through advancing to arrange communication passage; Advance to arrange to establish on the communication passage gas working medium heat absorption atmospheric heater said, advance to arrange communication passage and establish gas-liquid separator with the place of connection of said relief opening said, the liquid outlet of said gas-liquid separator is communicated with said cylinder through liquid working substance high pressure send-back system; Said intake valve, said exhaust valve and said liquid working substance high pressure send-back system are controlled by process control mechanism; Realize that said liquid working substance high pressure send-back system is transmitted back to liquid working substance in the said cylinder when gas working medium is increased substantially by the temperature and pressure after the degree of depth compression in said cylinder, said liquid working substance mixes with said gas working medium that being heated gasifies further improves pressure; Promote said descent of piston work done; By the needed merit of degree of depth compression process, said piston is to work done outside the system greater than said gas working medium for the amount of said descent of piston work done, the temperature before the temperature of the said gas working medium behind the expansion working is reduced to and is lower than said gas working medium and is compressed; After said gas working medium after the cooling self absorbs heat in said exhaust valve is discharged into said gas working medium heat absorption atmospheric heater when said piston stroking upward and heats up; When said descent of piston, in said intake valve was inhaled into said cylinder, said gas working medium was got into next circulation by degree of depth compression once more when said piston stroking upward.
On the circulation passage of said liquid working substance, establish liquid working substance heat absorption atmospheric heater.
Between gas working medium heat absorption atmospheric heater and said suction port, advance to arrange to establish on the communication passage gas working medium heat absorption low-grade heat source heater.
