The invention discloses an adsorbing condensing type oil
vapor recovery device for effectively preventing adsorption temperature rise and an oil
vapor recovery method. The device comprises an oil vapor inlet, a first valve set, an adsorption tank set, a second valve set, a clean gas exhaust port, a
vacuum pump set, a first-level oil vapor condenser, a second-level oil vapor condenser, a third-level oil vapor condenser and a
check valve, wherein the first valve set is composed of a gas
inlet valve set under the adsorption tank set and a vacuum valve set in parallel connection with each other; the second valve set is composed of an
exhaust valve set above the adsorption tank set and a blow-down valve set in parallel connection with each other; the blow-down valve set, the adsorption tank set, the vacuum valve set, the
vacuum pump set, the first-level oil vapor condenser, the second-level oil vapor condenser, the third-level oil vapor condenser and the
check valve are connected in turn; the
check valve is connected with the oil vapor inlet; the oil vapor inlet is connected with the gas
inlet valve set, the adsorption tank set, the
exhaust valve set and the clean gas exhaust port in turn; a
solid-
liquid phase variable
energy storage substance is filled into the adsorption tank set.
