Waste heat power generator

摘要

The waste heat power generator (G) includes: an evaporator (1) configured to produce steam of a working medium; a power-generating device (2, 2a, 2b) configured to generate electric power while expanding the steam; a condenser (3) configured to condense the steam which has passed through the power-generating device (2, 2a, 2b); and a pump (5) configured to send the condensed working medium to the evaporator (1). A bottom portion (BT) of the power-generating device (2, 2a, 2b) is provided with a discharge port (8) configured to discharge the working medium liquefied inside the power-generating device (2, 2a, 2b), to the outside thereof. A discharge pipe (6) is provided in which one end thereof is connected to the discharge port (8) and the other end thereof is disposed in a channel for the working medium between the condenser (3) and the pump (5).

1. A waste heat power generator comprising:
an evaporator configured to collect waste heat energy and to produce steam of a working medium; a power-generating device configured to generate electric power while expanding the steam; a condenser configured to condense the steam which has passed through the power-generating device; and a pump configured to send the working medium condensed at the condenser, to the evaporator, wherein a bottom portion of the power-generating device is provided with a discharge port configured to discharge the working medium liquefied inside the power-generating device, to the outside thereof, and a discharge pipe is provided in which one end thereof is connected to the discharge port formed in the power-generating device and the other end thereof is disposed in a channel for the working medium between the condenser and the pump, wherein the power-generating device includes:
an impeller configured to be rotationally driven by the steam;a generator configured to generate electric power by being driven using rotational driving force of the impeller;a rotary shaft configured to transmit the rotational driving force of the impeller to the generator;a casing provided with a first chamber containing the impeller, a second chamber containing the generator, and a communication hole configured to guide the liquefied working medium from the first chamber to the second chamber.
