EVAPORATION SYSTEM OF VOLATILE MATTER FOR RECYCLING OF EXTRACTED OIL SHALE RESIDUE AND RECYCLING METHOD USING THEREOF

摘要

The present invention relates to recycling and circulation utilization methods, and using this, wherein recirculating system can produce dry oil shale slag by introducing sludge, these are extracted oil shale residue, into light crude oil mixing channel; And the enough heavy crude of mixing has been separated, because utilizing light crude oil or extractant; In addition recycling heavy crude and extraction reagent/light crude oil sludge separation apparatus; Preliminary store oil shale sludge, carries out extraction residue, and middle storage is transferred to evaporation recycling light oil device; Reagent/light crude oil is extracted in recycling, these organic matters can be recycled finally and be reduced as far as possible. Recycling heavy crude can increase in addition recycling heavy crude, light crude oil oil/extractant and remain in sludge, these are extracted oil shale residue and are recycled in extractant by which heavy crude. The reduction of the content of organic matter is finally discharged by removing oil shale residue light crude oil oil/extractant oil shale residue, thus carries out post-processing environmentally friendly grade. In addition, the amount of heavy crude and extractant, which can be minimized, remains in sludge by extracting heavy crude from oil shale after sludge separation apparatus and evaporation process, because utilizing light crude oil or extractant. The dry oil shale, which resides, can be utilized as additive for bituminous pavement, allow to recycle the stable mode of remaining extraction oil shale environmental protection. ;The 2015 of copyright KIPO submissions
