Problems solved by technology

[0007] (3), the exhaust temperature of itself is high, and must be above the ambient temperature; the actual exhaust temperature is generally around 200 degrees; serious environmental pollution
[0008] (4) Relying on mineral energy, complex equipment structure, serious heat loss, and low energy conversion efficiency; its own energy conversion efficiency is only about 25%, and turbocharging or vacuum technology (this technology is mainly used for heating and cooling) co-production and gas liquefaction energy recovery, etc.), part of the waste heat of exhaust steam can be used, and the overall efficiency can be increased to about 30%-40%, but the efficiency is still low
[0011] (1), complex organization
The axis of the piston is vertically intersected with the axis of the work output shaft. Therefore, the reciprocating motion of the piston cannot cause the output shaft to produce circular motion. Therefore, the output shaft must be made into a crankshaft, and the lever effect generated by the connecting rod can push the shaft to produce circular motion. Output kinetic energy to the outside world; the linear reciprocating motion of the piston in the cylinder makes the energy conversion process and structure of the system more complicated; the mechanical friction loss and deflagration high temperature generated by its two major mechanisms, namely the crank connecting rod mechanism and the gas distribution mechanism In order to reduce the heat loss, two major systems are needed, namely, the lubrication system and the heat dissipation system to ensure its normal operation.
[0012] (2), large mechanical friction area
[0014] (4), low efficiency, about 25%
After adopting turbocharging technology (this technology is mostly used in auxiliary systems of internal combustion engines), part of the exhaust waste heat can be used, and the overall efficiency is increased to about 30%, but the efficiency is still low

Embodiment 1

[0060] Such as Figure 1 to Figure 9 As shown, the rotor of this embodiment includes two circular shell plates 1 arranged parallel and side by side along the same axis, and a circle of vortex plate groups is fixedly connected between the two circular shell plates 1, and the vortex plate set can be as follows: Figure 4 with Figure 5 As shown, only one vortex plate 2 is included, and it can also be as Image 6 with Figure 7 Shown includes two vortex plates 2, can also be as Figure 8 with Figure 9 Four swirl plates 2 are shown. Each vortex plate group corresponds to a coaxial virtual cylinder 3 of the shell plate 1, and the vortex plate 2 composed of the vortex plate group is evenly wound around the virtual cylinder 3 along the tangential direction of the virtual cylinder 3 corresponding to the vortex plate 2 Outside, at least one of the two circular shells 1 is vertically connected to the center of the circular shell 1 with a hollow central shaft 4 , and the central sh...

Embodiment 2

[0069] The expander 15 is provided with a throat 16 on the base 8 at the opening 12 of the cavity, and the inlet of the throat 16 is used as the inlet of the expander 15 . The arrangement of the throat 16 can maintain the stability of the pressure in the cavity 9 .

Embodiment 3

[0071] Such as Figure 14 , Figure 15 As shown (the direction indicated by the arrow in each figure of this embodiment is the flow direction of the working fluid), this embodiment provides an engine, the difference between this engine and the expander 15 in Embodiment 2 is that:

[0072] The base 8 of the expander is provided with a fuel supply and ignition device 17 at the cavity 9 outside the tangential opening 6 . Due to the provision of fuel supply and ignition means 17, the cavity 9 between the throat 16 and the rotor tangential opening 6 forms a combustion chamber. The engine of this embodiment can be started at any time and output mechanical energy externally. In addition, when the thermal energy of the heat source of the expander 15 system in Embodiment 1 or Embodiment 2 is unstable, the use of the expander 15 in this embodiment can ensure the temperature of the working fluid entering the rotor of the expander 15 .

Abstract

The invention discloses a rotor. The rotor comprises two round shell plates which are arranged in parallel along the same axis; at least one circle of vortex plate group is fixedly connected between the two round shell plates; each circle of vortex plate group comprises at least one vortex plate and corresponds to a coaxial line virtual cylinder of a shell; the vortex plates of each circle of vortex plate group are uniformly wound outside the virtual cylinder along the tangential direction of the virtual cylinder corresponding to the circle of vortex plate group; a hollow central shaft is vertically and fixedly communicated with the center of at least one of the two round shell plates; an axial opening is formed at the outer end of the central shaft; and a tangential cut is formed on a part between the outer ends of adjacent vortex shell plates at the outermost circle. The rotor is simple in structure and convenient to use, can be used as the rotor of an expansion machine and an engine and also can be used as a compressor. By the rotor, the internal energy and the kinetic energy of working fluid can be effectively transformed into mechanical energy for the rotor to rotate, and the comprehensive efficiency is greatly improved.
