Abstract

The invention discloses an oil-bearing solid waste resource utilization device and method. The device comprises a hopper, a feeding device, a fluidized bed pyrolytic reaction distiller, a dust collector, an air pre-heater, a booster fan, a combustor, a buried pipe heat exchanger, a condenser, a fluidizing air pre-heater and an air chamber. The method includes the steps that oil in solid waste is pyrolyzed and distilled, pyrolyzed and distilled gas serves as an inert circulating medium, pyrolytic gas is cooled and liquefied in the air pre-heater and the condenser and separated to obtain fluid oil, reclamation is achieved, and noncondensing gas serves as pyrolytic fuel; after fresh air is heated in the air pre-heater, the fresh air, the noncondensing gas and make-up fuel combust and become high-temperature gas to provide heat for the fluidized bed pyrolytic reaction distiller. According to the device, oil in the oil-bearing solid waste is separated, solid waste resource utilization is achieved, and the effects of reducing environmental pollution and improving solid waste reclamation are achieved at the same time.

Description

technical field [0001] The invention relates to the application fields of petroleum, chemical industry, energy, etc., and specifically relates to a device for pyrolysis, distillation, refining, liquefaction and collection of oil contained in solid waste to realize resource utilization and a preparation method thereof. Background technique [0002] At present, the occurrence of fossil energy resources is uneven, and the development is difficult. It has been proved that the reserves of high-quality energy such as oil and natural gas are seriously insufficient. Coupled with backward energy utilization technology, unbalanced energy structure, and low utilization, under the conditions of rapid economic growth, my country's energy consumption is faster than other countries, and the threat of energy depletion may come earlier and be more serious. [0003] Oily solid waste mainly comes from human production and consumption of petroleum. In the process of developing and utilizing pe...
