A, the internal pressure of inlet pressure transducer (13) detection Oil/Gas Pipe (24), when pressure reaches maximum saturation pressure value,
Control unit (12) first controls inlet solenoid valve (14) closing, then controlling thrust device (4) work engages clutch；
B, motor exhaust is discharged from the exhaust pipe of engine (2) and turbine (1) is pushed to rotate, and drives clutch, jackshaft (9)
Operation is slowed down by retarder (10), drives active carbon (15) rotation, the oil gas adsorbed by active carbon (15) by output shaft (11)
Oil liquid is formed under the action of the centrifugal force to fall on canister (16) side wall；
C, control unit (12) control oil liquid outlet solenoid valve (22) is opened, and oil liquid flow back into fuel tank by oil liquid return pipe (25)
(31) in.
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) detects Oil/Gas Pipe (24) internal pressure, when pressure does not arrive maximum saturation pressure value, control unit
(12) whether the detection time for judging inlet pressure transducer (13) is more than the preset time, if it does, control unit
(12) oil gas vent solenoid valve (17) are controlled and air inlet pipe inlet solenoid valve (26) is opened, piston (36) movement makes combustion chamber (27)
Internal volume increases to which pressure declines, and is desorbed under the action of pressure difference by the oil gas that active carbon (15) are adsorbed, abjection
Oil gas is by burning in oil gas return pipe (19) flow into combustor (27).
