Description
Technical Field
The invention relates to an engine, in particular to a gear rotor engine and a gear rotor engine unit.
Technical Field
The motor outputs mechanical work by converting electric energy by using a motor rotor; the piston type internal combustion engine outputs mechanical work by utilizing high-temperature and high-pressure working medium energy generated by the combustion of the converted fuel of the crank connecting rod mechanism; the turbine also utilizes a blade type turbine rotor to convert the energy of high-temperature and high-pressure working media to output mechanical work. Therefore, the rotors in various forms are used for converting working medium energy to output mechanical work outwards by the engine device.
The efficiency of converting electric energy by motor is up to 98%, and the heat energy power equipment in the existent technology includes piston type internal combustion engine, gas turbine engine and steam turbine engine, and the enthalpy drop of rotor converting working medium (i.e. energy) and heat efficiency of outputting mechanical work are less than 45%?, except small portion of inevitable heat loss, one piston type internal combustion engine crank connecting rod mechanism can normally work by water cooling, and its waste heat quantity is greater than half of the used heat quantity, and two piston type internal combustion engines are basically characterized by that when the high-temp. high-pressure working medium is used to drive piston to do work once, it can discharge out waste gas whose enthalpy value is very high, and when the three-turbine engine adopts multi-stage expansion, every stage is blade type turbine, and waste gas whose enthalpy value is very high.
The piston type internal combustion engine indirectly drives a crankshaft to rotate by the linear motion of a piston, the structure is complex, a gas turbine engine unit and a steam turbine engine unit are both direct rotary engines, the steam turbine engine unit is slow to start, the gas turbine engine is fast to start, the structure is simple, and cooling water is not used, so that the gas turbine engine is the most ideal engine, but is only applied to tanks and special vehicles at present. In order to apply the gas turbine engine to the field of automobiles, the key technical problems of high cost, high temperature and high pressure resistance, large volume, low conversion heat efficiency, large working medium flow, small output torque, high rotating speed, more than 1000 kilowatts of output power, difficulty in working in an unstable flowing working state and the like of a turbine of the gas turbine engine need to be solved.
The foregoing illustrates that the prior art thermal power plant configuration suffers from a number of technical drawbacks.
The theoretical analysis shows that: after receiving heat in the working medium flowing process, the enthalpy h of the state at this time is composed of thermodynamic energy u of the flowing working medium and pushing power pv for promoting the working medium to flow (namely the enthalpy h is u + pv), p represents pressure, namely the pushing power pv contains pressure energy to push an object to do work, and the thermodynamic energy u has no pressure; only when the push power pv is fully consumed, thermodynamic energy u can be fully converted into the push power pv, and enthalpy drop of the working medium can be fully utilized to be converted into mechanical power. It can be seen that the piston engine and the turbine engine in the prior art do not fully consume the push power pv first, so that the thermodynamic energy u is discharged outside without being fully converted into the push power pv, thereby having low heat efficiency due to low enthalpy drop utilization rate of the working medium.
In order to improve the thermal efficiency, patent No. 201410415779.3 discloses a method for improving the efficiency of a turbine engine and a device thereof, which is a rotary screw engine, and belongs to a rotary screw turbine engine, and does not fully consume the thrust power pv.
In the prior art, although there are various technical measures for improving the thermal efficiency, no report is found on an engine which can fully consume the pushing work pv and a technical scheme how to improve the thermal efficiency by using the engine. At present, energy conservation and emission reduction are advocated, and it is obvious to develop an engine capable of consuming propulsive power pv first, and the engine is very worthy of exploration and research.

The technical scheme is that the gear rotor engine is used as a front stage, the steam turbine is used as a rear stage, and the gear rotor engine is driven by the steam turbine or not.
The clockwise rotation or the anticlockwise rotation of the gear rotor engines of the two units are determined by the clockwise rotation or the anticlockwise rotation direction selected by the starter in advance, the clockwise rotation or the anticlockwise rotation is irrelevant to the determined air inlet pipe and the exhaust pipe, but when the power connection of the turbine engine, the steam turbine and the spiral pipe rotor engine and the gear rotor engine works together, the output torque direction of the turbine engine, the steam turbine and the spiral pipe rotor engine is required to be consistent with the output torque direction of the gear rotor engine.
