Abstract

A pyrolysis resource utilization system and method for oily sludge are disclosed. The system includes a mechanical dehydration unit, a flue gas drying unit, a rapid pyrolysis unit, a pyrolysis gas condensation unit, a cooling unit, an oil-water separation unit, a heat carrier lifting unit, a heating unit and a heat carrier separation unit. The oily sludge after mechanical dehydration and drying with flue gas is fed into the rapid pyrolysis unit together with a high-temperature heat carrier; generated pyrolysis gas passes through the pyrolysis gas condensation unit to obtain oil and noncondensable gas a part of which is fed into the heating unit and combusted; residues and the heat carrier after pyrolysis are fed into the heating unit through the heat carrier lifting unit, and then ash residues and the heat carrier are separated through the heat carrier separation unit; the separated high-temperature heat carrier is fed into the rapid pyrolysis unit for repeated use; and generated fluegas is conveyed to a flue gas drying unit for cyclic use. A process of cyclic heating and pyrolysis utilizing a large-particle solid heat carrier is adopted to significantly increase the oil extraction yield, and coking of the rapid pyrolysis unit can be prevented, thus ensuring continuous operation of the unit.

Description

technical field [0001] The invention belongs to the technical field of resource utilization of waste, and in particular relates to an oil sludge pyrolysis resource utilization system. The present invention also provides a method for using the above-mentioned system to carry out pyrolysis resource utilization of oil sludge. Background technique [0002] A large amount of oily sludge is produced in oilfield mining in my country every year. According to statistics, more than 1 million tons of oily sludge is added every year in my country. Because oily sludge contains water, benzene series, sulfides, hydrocarbons and sediment, not only Occupying a large amount of land and causing pollution, oily sludge has been listed as hazardous solid waste by the country, and the treatment of oily sludge has become an urgent problem in the oilfield mining industry. [0003] At present, the treatment methods of oily sludge mainly include: chemical treatment, biological treatment, landfill comp...
