Workflow description of the device:
the oil-containing material is lifted and conveyed to an inlet of an upper conveying belt 13 through a lifting device, the oil-containing material is uniformly spread on the upper conveying belt 13, the upper conveying belt 13 uniformly conveys the oil-containing material to the other end of a heat recovery pyrolysis furnace 10, a heating body 11 is heated in the conveying process, a heat energy recycling system 12 is used for heating, and the upper conveying belt 13 and the lower conveying belt 14 perform heat exchange to heat the oil-containing material to a pyrolysis distillation reaction; and the pyrolysis distillation is completed in each section through each temperature zone section. And after being conveyed to the other end, the conveyor belt is overturned and naturally falls onto the lower conveyor belt 14. The lower conveyor belt and the upper conveyor belt move oppositely and are conveyed from a high temperature area to a low temperature area, and the high temperature materials respectively pass through the high temperature area, the sub-high temperature area and the low temperature area in sequence. And the heat of the oil-containing material is exchanged by radiation and convection in each temperature zone and the oil-containing material of the upper conveyor belt, so that the heat of the oil-containing material is absorbed and utilized by the heat exchange in each temperature zone. After the heat of the oily material is exchanged and utilized, it is transferred to the outlet end and turned over to fall into a container 20 (e.g., a mud storage tank) disposed thereunder. Oil vapor generated by pyrolysis of oil-containing materials is collected in sections through a dome at the top of the reaction furnace and is conveyed to a distillation vapor cooling unit 40 through a pipeline arranged on the dome, and after condensed oil dirt is recovered, noncondensable gas is reserved to a catalytic combustion device 50 through a pipeline at the top of the tank group for catalytic combustion harmless treatment. The tail gas after catalytic combustion contains a large amount of heat energy (about 600), after the waste heat is recovered by the tail gas through a heat energy recycling system, the tail gas is discharged, the condensed and collected oil product is pumped and pumped into an oil storage tank for collection and storage, and oil-water separation operation is further carried out at regular intervals to improve the quality of the recycled oil product, and the water for cooling the slip gas is recycled to a water treatment device for innocuous treatment and recycling after cooling.
The foregoing description is only illustrative of the preferred embodiments of the present invention, and therefore should not be taken as limiting the scope of the invention, for all changes and modifications that come within the meaning and range of equivalency of the claims and specification are therefore intended to be embraced therein.
