The application discloses an energy-saving and environment-friendly turpentine processing technology without additional water, which comprises the following steps: 1) pressure conveying: turpentine is pressed into a melting kettle by pressure difference; 2) melting: turpentine oil and oxalic acid are added into the turpentine, and the material is melted by heating and stirring of heat conducting oil; 3) precise filtration: the melted turpentine is pressed into a high-position kettle, and two-stage filtration is sequentially carried out by using the height difference; and 4) reduced-pressure distillation: the filtered turpentine is pressed into a distillation kettle, vacuum is drawn, the kettle is heated by heat conducting oil, and distillation is carried out; turpentine oil is obtained by evaporating the liquid and removing water; and colophony is obtained by releasing the substance at the bottom of the kettle. The application adopts the pressure conveying mode to replace the traditional water dilution screw conveyor; the multi-stage precise filtration is adopted to remove impurities, the water washing and multi-stage clarification procedures in the traditional process are omitted, and the problems of large water consumption and high wastewater discharge in the turpentine processing are solved. The middle-layer turpentine liquid generated by the oil-water mixture is eliminated, the post-processing procedure is omitted, and the production efficiency and resource utilization rate are improved.

According to the utility model, turpentine in the evaporation heavy sewage tank can be separated, and the evaporation efficiency of the evaporation system is improved.

This invention discloses a slag extractor for extracting turpentine oil from molten slag, relating to the field of turpentine oil extraction technology. The slag extractor includes: a servo motor fixedly connected to the center of the top of the slag extractor body; a rotating shaft penetrating the top of the slag extractor body and fixedly connected to the servo motor; a conveying blade fixedly connected to the lower part of the rotating shaft; and a spraying blade fixedly connected to the upper part of the rotating shaft. The conveying blade and the spraying blade form a continuous unit, with the distance between them gradually increasing along the height of the rotating shaft. A steam pipeline is fixedly connected to several connecting pipes penetrating the slag extractor body, and a conical control head is fixedly connected to the side of each connecting pipe. By setting the servo motor to drive the rotating shaft to rotate at a low speed, the rotating shaft drives the conveying blades and the spraying blades to rotate slowly, conveying the molten slag to the steam. The steam is diverted through the steam pipeline and then sprayed out through the connecting pipes and the control head. The reciprocatingly conveyed molten slag directly contacts the steam, changing the contact path between the steam and the molten slag.

Provided in the present invention are a green and efficient method and apparatus for hydrating caryophyllene. The process comprises the following steps: mixing a solid acid catalyst with a heavy fraction of turpentine oil to obtain a mixed solution; adding water to the mixed solution, wherein a mass ratio of the water to the heavy fraction of turpentine oil is 100 : (10-15); after completing the reaction and / or filtering off the catalyst, obtaining a filtrate; and subjecting the filtrate to vacuum distillation and recrystallization to obtain the product. The preparation method is simple, can achieve a raw material conversion rate of 90-99%, and features mild reaction conditions, high product selectivity, few side reactions and easy operation. Meanwhile, the reaction efficiency is high, and the catalyst can be recycled after being filtered, which better conforms to the concept of green chemistry.
