Abstract

The invention discloses a production method of ground rosin; the production method includes the steps of crushing, device cleaning, dissolution agent addition, water removal, feeding, standing, turpentine releasing, distillation, oil-water separation, residue cleaning, residue distillation, residue removal and the like. The production method disclosed by the invention is extremely low in energy consumption, raw material residues can meet heat sources required for the production, and fire coal or firewood is not used; no sulfur dioxide is discharged and no any produced sewage is discharged in the combustion process of residue biomass fuels with wood properties; the recovery rate of rosin can reach 98%, and the produced rosin has the performance indicators reaching the grade 1 of national standards.

Description

technical field [0001] The invention relates to a technique for obtaining rosin and turpentine by dissolving and separating ground rosin, in particular to a production method of ground rosin. Background technique [0002] Pine resin is a mixture of rosin and turpentine, and it is a colorless and transparent viscous liquid when it first flows out from the tree body. At present, turpentine is obtained by manual collection, and then processed into rosin and turpentine, which become important chemical raw materials. There are two kinds of processing methods for artificially collected rosin: steam method and drip method. The steam method uses the water vapor produced by the steam boiler as the heat source. First, the pine resin is heated and dissolved, and the large impurities are filtered out, and then the fine impurities and most of the water are further removed by a clarification method, and finally the net liquid is put in the still Turpentine is distilled inside and rosin ...
