Control unit（12）First control inlet solenoid valve（14）Close, then control thrust device（4）Work engages clutch；
B, motor exhaust are from the exhaust pipe of engine（2）It is middle to discharge and promote turbine（1）Rotation, drives clutch, jackshaft（9）
Operation, by decelerator（10）Slow down, by output shaft（11）Drive activated carbon（15）Rotate, by activated carbon（15）The oil gas of absorption
Fluid is formed under the action of the centrifugal force to fall in canister（16）On the wall of side；
C, control unit（12）Control fluid outlet solenoid valve（22）Open, fluid passes through fluid return duct（25）It flow back into fuel tank
（31）It is interior.
5. a kind of desorption method of the centrifugal canister desorption apparatus of exhaust gas turbine as claimed in claim 2, it is characterized in that：Entrance pressure
Force snesor（13）Detect Oil/Gas Pipe（24）Internal pressure, when pressure does not arrive maximum saturation pressure value, control unit
（12）Judge inlet pressure transducer（13）Detection time whether exceed the time set in advance, if it does, control unit
（12）Control oil gas vent magnetic valve（17）With air inlet pipe inlet solenoid valve（26）Open, piston（36）Motion makes combustion chamber（27）
Internal volume increase declines so as to pressure, by activated carbon（15）The oil gas of absorption is desorbed in the presence of pressure differential, abjection
Oil gas passes through gas collection pipe（19）Flow into combustor（27）Interior burning.
