Abstract

The invention discloses an environmentally- friendly energy-saving type recycling treatment system for an oil sludge circulating fluidized bed, and relates to the field of environmental protection, energy saving and waste recycling. Oil sludge is treated and then gets harmless, reduced and recycled, and liquid state fuel oil and combustible gas are recycled and merged into a user pipe network. Thesystem mainly comprises a circulating fluidized bed incinerator, two-level gas-solid cyclone separation devices, a flue gas secondary combustion room, steam superheater, an air preheater, a waste heat boiler evaporator, a waste heat boiler economizer, a glue gas mixer, a cloth bag dust collector, a deacidifying washing tower, an induced draft fan, a chimney, a gasification reactor, a gas-solid separator, a condenser and a gas holder. Gas state fuel and liquid state fuel oil with high quality are obtained through oil sludge pretreatment, combustion, gas-solid cyclone separation and condensingdehydration, meanwhile, waste heat of the system is recycled for gasification, and ash is recycled. All components of the oil sludge are separated thoroughly, the rate of resource recycling is high, equipment operates stably and reliably and occupies small land, and the process of oil sludge treatment is simple.

Description

technical field [0001] The invention relates to the technical field of environmental protection, energy saving and resource utilization of waste, in particular to an environment-friendly and energy-saving resource treatment system of oil sludge circulating fluidized bed. Background technique [0002] Oily sludge mainly refers to the oily sludge formed by crude oil and soil due to various reasons, and the oily sediment brought out by the system during normal production of oilfields. The main components are crude oil, mud and water. Oil sludge is mainly produced in oil fields and refineries. According to its source, it can be divided into three types: the oil sludge formed in oilfield mining production and operation construction, the tank bottom sludge produced in the natural settlement of various storage tanks, and the oil sludge produced in petroleum refining. The "three muds" are the bottom mud of the grease trap, the scum of the flotation tank and the bottom mud of the cru...
