The invention discloses a heat-conduction oil skid-mounted recycling system and a heat-conduction oil recycling method. The recycling system comprises a heat-conduction oil evaporation tank, an evaporation tank condenser, a steam injector, a heavy oil pump and a heat-conduction oil pump which are integrated on a skid-mounted structure. Heat-conduction oil is evaporated through the heat-conductionoil evaporation tank, evaporated gas is condensed through the evaporation tank condenser, and then is recycled through the heat-conduction oil pump, and heavy oil components are recycled through the heavy oil pump; and non-condensable gas in the heat-conduction oil evaporation tank is discharged through the steam injector to maintain the vacuum degree of the heat-conduction oil evaporation tank. By adopting the recycling system and the recycling method to recycle the heat-conduction oil, the device is flexible and easy to operate, does not depend on the operation environment of a factory, hashigh independence, can meet high-efficiency recycling of the heat-conduction oil in different regions, and does not need additional heat sources or power facilities; the heat-conduction oil can be recycled on line, and production and operation of the original device are not influenced; and in the recycling process, the system is stable in running, high in recycling rate and capable of realizing automatic monitoring and control; and the recycling process is energy-saving, environmentally friendly and pollution-free.
