Embodiment 1
[0026] Taking the oily sludge at the bottom of a crude oil settling tank of a joint station of an oil production plant in northern Shaanxi as an example, its initial water content is 40%, and it contains 35% organic matter, of which gasoline and diesel components with a boiling point below 350 °C account for 12%, and heavy oil components It accounts for 13%, and the mud content is 25%.
[0027] The vertical steam fluidized furnace of the present invention has a material inlet hopper on the top of the tower, a material outlet on the bottom of the tower, and a screen-like tray, a rake arm and a rake arm drive device inside, and the rake arm drive device drives the rake The arm drives the sieve tray to rotate. The lower part of the vertical steam fluidized furnace is equipped with a multi-stage metal screen plate, the lower part of the rake arm is equipped with a steam ejector, and the outer wall of the vertical steam fluidized furnace is provided with an insulation layer.

Embodiment 2
[0038] Taking the oily sludge at the bottom of a crude oil settling tank of a joint station of an oil production plant in northern Shaanxi as an example, its initial water content is 40%, and it contains 35% organic matter, of which gasoline and diesel components with a boiling point below 350 °C account for 12%, and heavy oil components It accounts for 13%, and the mud content is 25%.
[0039] The specific processing method is as follows:
[0040] (1) The oily sludge at the bottom of the high-viscosity tank is dehydrated and reduced by a plate-and-frame filter press, and used as a material for treatment, with a moisture content of 20%;
[0041] (2) Chemical detackification: Spray chemical detackifier in the sludge storage tank. The chemical detackifier contains 5% organic amine and 1% surfactant. It is a fluorine-containing high-efficiency surfactant. Amines and surfactants decompose the wax and asphaltene on the surface of the oil sludge to reduce the surface viscosity. At...
