INDUSTRIAL TREATMENT METHOD AND DEVICE FOR OIL FIELD WASTES

摘要

An industrial treatment method for oil field wastes comprises: performing sampling analysis on oil field wastes, and preheating to 80°C to 300°C using high-temperature steam or thermal conduction oil; then performing microwave pyrolysis treatment, controlling pressure at -5000 to -100 Pa, and obtaining treated solid substances and gas; condensing, separating and purifying the gas and recycling the gas so as to obtain water, oil and non-condensable gas. An industrial treatment device for oil field wastes comprises a feed hopper, a dryer, a microwave heating cavity, a microwave generator, a heating device, and a condensation, separation and purification device. The feed hopper is connected to the dryer. The dryer is connected to the microwave heating cavity. A steam or thermal conduction oil outlet of the heating device is connected to a steam or thermal conduction oil inlet of the dryer. Gas outlets of the dryer and the microwave heating cavity are both connected to the condensation, separation and purification device. The microwave generator is connected to the microwave heating cavity. The treatment method and device have good treatment effects, high energy utilization rate and high economic efficiency.
