Problems solved by technology

Although this process is mature, it consumes a lot of energy. Each ton of rosin consumes 1 ton of steam. Therefore, the factory needs to use a large boiler to supply steam, which has an impact on the environment.

Abstract

The invention relates to a resin short path distiller and a resin distillation process. The distiller comprises a feed opening 1, a resin liquid distribution ring 2, a molecule evaporation surface 3, a turpentine tray 4 and an outlet 5, a rosin outlet 6, a heating jacket 8, a molecule evaporation tube consisting of a vacuum interface 10 and a flange 11, and a molecule cooler consisting of a waterinlet 12, a water outlet 13, a tooth-shaped corrugated molecule cooling surface 14, a flange 15 and a seal bottom. The evaporation surface is preheated to 130DEG C to 140DEG C, and vacuumized to 50Pato 100Pa; after cooling liquid is injected into the cooler, the pre-heated resin liquid is put into the resin liquid distribution ring; the resin liquid is distributed into a liquid membrane which flows downwards along the molecule evaporation surface and is heated by the evaporation surface, so that molecule distillation is carried out; turpentine molecules escape from the liquid surface and arecooled by the molecule cooling surface into turpentine which flows down to the tray and flows into a storage tank P1 from the outlet 5; and the rest rosin of the liquid membrane flows into a storage tank P2 from the outlet, and the distillation process lasts for 10s to 15s. The resin distillation process provided by the invention is simple and easy to operate, saves above 70 percents of heat compared with a distillation process, so that the color of the rosin is lighter.

Description

1. Technical field [0001] The invention belongs to the technical field of rosin processing. 2. Background technology [0002] Rosin is a widely used industrial raw material. The pine resin of pine trees contains rosin and turpentine, and rosin is obtained by steaming turpentine. After dissolving, settling, and removing impurities, the pine resin is diluted into a fat liquid with good fluidity, and then enters the distillation process. In the current production process, two streams of steam work when distilling fat liquid. The first is indirect steam, which transfers heat through coiled tubes, and heats the fat liquid continuously until the distillation ends at about 195°C; the second is direct steam. , it is sprayed into the fat liquid, mixed with the fat liquid to azeotropically extract the turpentine. This process is called the steam method, and it is the mainstream process in the rosin industry in all countries in the world. Although this process is mature, it consume...
