FIELD: process engineering.
SUBSTANCE: invention relates to treatment of soil contaminated by oil products. Proposed device comprises worms to transfer contaminated soil, heater of the latter, evacuated chambers and boxes, gas phase condenser and worm devices equipped with plasma guns. Said worm devices comprises conical worm with small depth of worm grooves and low worm blades, while plasma guns are arranged in temperature controlled space of worm device. Worm device proportioner represents a worm conveyor with vertical and horizontal components. Worm devices are pipeline-communicated with refrigerators to allow consecutive stepwise condensation of different oil products in different drain pipes.
EFFECT: improved ecology, higher efficiency and safety.
