The mixing oil solution (solvent and coal tar) filtered is evaporated, and is kept completely separate solvent and coal tar；
S10：Solvent cooling is reclaimed：Cooling liquid is carried out to the solvent evaporated in step S8 and step S9, and cooling
Solvent delivery afterwards is entered oil water separator and reclaimed；
S11：Vent gas treatment：Step S4, step S5, step S7 and step the S10 tail gas produced are handled, it is reached
Emitted after mark.
Further：The grain size specification of coarse fodder is 10-20mm in described step S1, the grain size specification of fines for 10mm with
Under.
Further：By the moisture control in ore deposit asphalt material in 2-4% in described step S2.
Further：The proportioning of coarse fodder and fines is 1 in described step S3：1, the proportioning of the fines and stone is 1：
1.5。
Further：Described step S5 extraction temperature is controlled at 50-55 DEG C, and extraction time is 30-45min.
Further：Heating and temperature control in described step S8 is at 105-115 DEG C.
Further：Evaporating temperature in described step S9 is controlled at 110 DEG C.
After the above method, by the present invention in that coarse fodder is mixed to form " cellular " with fines or fines with stone
Compound, to increase feed liquid contact area, strengthen the ability of the solvent penetration bed of material, so as to improve the extraction yield of coal tar；And
And can by using solvent and the initial boiling point destructive distillation point of coal tar difference, not up to coal tar evaporate a little before first solvent is entered
Row evaporation, then carries out cooling recovery, so as to play a part of reducing cost to vaporized solvent.
