Thermal insulation layer can all or part ofly be set up in the periphery at other position of described explosive motor and system, with the thermal efficiency of further raising motor.
The present invention is divided into a plurality of step energy resources district with the hot system (being the waste heat system) beyond the firing chamber by energy grade in conjunction with the characteristics of explosive motor.For the ease of understanding, existing is that example describes with three step energy resource districts.Step energy resource district A is the zone (being described cylinder sleeve working medium pressure-bearing passage) around the explosive motor cylinder liner, this zone is because the high speed relative movement of cylinder liner and piston, the radiating and cooling condition of having relatively high expectations, the temperature that is working medium will be hanged down relatively, thereby, in the present invention with the heating-up zone of step energy resource district A as working medium, in this district with the working medium heat temperature raising; Step energy resource district B is the zone (being described cylinder cap working medium pressure-bearing passage) in the cylinder head of top, explosive motor firing chamber, in this zone except that motion that can resistant to elevated temperatures valve and with the bump of valve seat, there is not other high speed relative movement, therefore, the radiating and cooling condition can relative mistake some, promptly the temperature of working medium can be higher, thereby, with the gasification zone of step energy resource district B, in this district, produce the gas phase working medium of High Temperature High Pressure in the present invention as working medium; Step energy resource district C is heat exchanger on the engine exhaust road (being described exhaust heat exchanger), this zone does not have moving element, promptly do not need special radiating and cooling condition, the temperature that is to say working medium can be very high, so in the present invention this is distinguished as the working medium overheated zone, in this district, make working medium overheated, further improve the temperature of working medium, and then improve the efficient of working medium circular work.
Working medium among the present invention can be the working medium of water or other type, for example: the working medium of ammonia, alcohols, ethers, alkanes and other type, as long as select according to the radiating and cooling condition of motor and the bearing capacity of system etc.
By among the present invention three step energy resource district A, B and the working medium passage of C, can directly or through control valve be communicated with.By selecting different working medium satisfying under the radiating and cooling condition of cylinder liner, according to the thermodynamic property (thermal capacitance, heat of vaporization, vapor tension temperature curve etc.) of working medium, step energy resource district A and step energy resource district B partly or entirely can be merged the one or more new step energy resource districts of formation.Yet step energy resource district C can part should all not merge with step energy resource district B, because if all fusion will not have the working medium overheated zone, thereby can reduce the temperature of gas phase working medium, thereby reduces working medium circular work efficient.Character according to type, operating conditions (being the temperature and the heat output in different step energy resources district) and the used working medium of explosive motor, the heat Balance Calculation or the experiment in all step energy resource districts can be carried out, the flow of working medium and the fusion rate in different step energy resources district can be determined according to calculating or experimental result.
Among the present invention, the working medium temperature in different step energy resources district can differ greatly, but when described liquid phase working fluid compression pump was not set, the sender matter pressure in all step energy resource districts increased successively by the opposite direction that working medium flows to.If the bearing capacity of described cylinder sleeve working medium supercharging passage is lower, can reduce the sender matter pressure in the described cylinder sleeve pressure-bearing working medium by described liquid phase compression pump is set.Because the setting individually or simultaneously of condensation liquid phase working fluid compression pump and liquid phase working fluid compression pump, and the setting of working medium pressure-bearing passage, make working medium under high pressure gasify, thereby eliminated the necessity that the gas phase working medium pump is set between working medium gasification zone and the working medium overheated zone, can effectively reduce the required a large amount of mechanical works of pumping gas phase working medium like this, thereby improve the efficient of system greatly.Exhaust heat exchanger is made as convection type, and then improves the temperature and the circular work efficient of hot working fluid.
For guaranteeing intensity of cooling near the cylinder sleeve of firing chamber, can make liquid phase working fluid at first enter herein cylinder sleeve working medium pressure-bearing passage after, flow from top to bottom, flow to described cylinder cap working medium pressure-bearing passage by the lower end outlet at last.
External-combustion engine among the present invention can be steam turbine, steamer or turbo machine etc., and the power of generation can be used as generating, supercharging etc., also can synthesize a power output source with explosive motor.Can set up thermal insulation layer by outside and other position of system for reducing heat loss, and then improve the heat recovery rate explosive motor.
Because working medium should be in sealing and circulating acting process, so be identical by the working medium quality (molal quantity) in each step energy resource district.In view of the above, can determine the heat transfer area and the heat transfer condition in different step energy resources district by heat Balance Calculation or experiment.
Principle of the present invention
The present invention is used the waste heat of the explosive motor thermal source as external-burning engine.For improving explosive motor UTILIZATION OF VESIDUAL HEAT IN efficient, produce useful work as much as possible, the present invention is divided into a plurality of energy parks with explosive motor waste heat system by energy grade according to the operating conditions of motor, promptly a plurality of step energy resources district.The energy grade difference in each step energy resource district is pressed energy grade height, makes working medium by low-grade each the step energy resource district that flows through successively to the high-grade district that distinguishes, in the work done of external-combustion engine place after condensate cooler enters low-grade step energy resource district again.According to the energy grade in different step energy resources district, be respectively applied for heating, gasification, the superheating process of working medium.By set both can satisfy the explosive motor different parts in a plurality of step energy resources district the radiating and cooling condition (for example, the temperature of working medium should be lower around the cylinder sleeve, the temperature of cylinder cap place working medium can be higher, and the working medium temperature in the exhaust heat exchanger can be higher), the waste heat that can make full use of different grades again forms high temperature gas phase working medium, and then increases substantially the acting ability of working medium.Because the setting individually or simultaneously of condensation liquid phase working fluid compression pump and liquid phase working fluid compression pump, and the setting of working medium pressure-bearing passage, make working medium under high pressure gasify, thereby eliminated the necessity that the gas phase working medium pump is set between working medium gasification zone and the working medium overheated zone, can effectively reduce the required a large amount of mechanical works of pumping gas phase working medium like this, thereby improve the efficient of system greatly.The present invention has following actively useful effect: can make full use of waste heat around the air cylinder sleeve of engine and the waste heat in the engine exhaust, thereby improve the thermal efficiency of motor, reduce the consumption of fuel oil, reduce the user cost of motor.
