The invention relates to a method for continuously distilling aromatic oil by subsectional temperature control. The method is characterized by comprising the following steps of: after cutting raw materials to crushed aggregates, falling to a mobile conveying device; and forming a close and independent distilling work station by different distilling area and corresponding steam areas; continuously passing through the crushed aggregates by all distilling work stations to complete distillation step by step. The method provided by the invention has the positive effects that the daily handling capacity is improved by continuous feeding, distillation and discharge. Through closed cutting, vapor-solid materials are more uniformly contacted, so that vapor collapse and short circuit are effectively avoided. The temperature is controlled by sub-sections and is gradually raised to the benefit of more adequate distillation-off of aromatic oil (conventional components) in raw materials; different azeotropes (coarse distilling materials) which are collected in sub-sections are overcome for the convenience of post-process. Higher temperature distillation is realized. Shallow distillation overcomes the deficiency that steam is hard to penetrate through material layer during distillation in a barrel, so that the thermal efficiency of distillation is improved.

The invention relates to an oil shale gas-solid heat carrier dry distillation and semicoke combustion electricity generation integral process, which is characterized in that oil shale crushed into at least 75mm is stored in a raw material cabin and is sieved, small-particle oil shale with the particle diameter smaller than 15mm and 15-75 mm large-particle oil shale are respectively conveyed into a left chamber and a right chamber of a medium-temperature gas indirect or direct heat exchange drying heater, and 15-75 mm large-particle oil shale subjected to heating and drying is subjected to gas heat carrier dry distillation; the small-particle oil shale with the particle diameter smaller than 15mm and semicoke are mixed and are subjected to solid heat carrier dry distillation; oil-gas mixtures generated by the solid heat carrier dry distillation are subjected to purification, condensation and separation treatment after sedimentation and gas-solid separation, shale oil is conveyed into an oil storage tank, one part of separated gas is used as heat carriers of the dry distillation of the 15-75 mm large-particle oil shale, and the rest gas is conveyed into a gas storage tank; superheated steam produced by semicoke consumption is conveyed into a steam turbine generator set for electricity generation; one part of semicoke consumption high-temperature hot ash is used as the heat energy of the dry distillation of the small-particle oil shale with the particle diameter smaller than 15mm; and the other part of discharged hot ash is cooled and is then conveyed to a building material factory.

The invention discloses a reduced pressure distillation device for rosin and belongs to the field of rosin processing. The reduced pressure distillation device for the rosin comprises a distilling pot main body, a condenser and a vacuum extraction device; a mixed steam outlet is formed in the top of the distilling pot main body; a rosin outlet, a steam inlet and an inert gas inlet are formed in the bottom of the distilling pot main body; a resin liquid channel, a stirrer and a rosin collecting tank are arranged in the distilling pot main body; the mixed steam outlet is connected with the condenser; the vacuum extraction device comprises a cushion cylinder and a vacuum pump; the cushion cylinder is connected with the distilling pot main body; a heating layer is arranged on an inner wall of the distilling pot main body. The resin liquid channel of the device can more sufficiently disperse the rosin into the main body, the stirrer can increase the heat exchange area of the rosin and the distilling efficiency can be increased. Compared with the traditional distilling pot, the reduced pressure distillation device disclosed by the invention has the advantages that the distilling rate is higher and the prepared turpentine and rosin are higher in quality.
