Abstract
The invention discloses a method for recycling rosin from waste rosin liquid. The method comprises the following steps: firstly, mixing waste rosin liquid, water, oxalic acid and turpentine in a weight ratio of 500-550: 180-220: 400-440: 1-3, heating to 155-165 DEG C, and obtaining a dissolving solution after keeping the constant temperature for 12-16min; secondly, filtering the dissolving solution with a 80-120-mesh filter screen to obtain filtrate; thirdly, standing the filtrate for 45-55min to obtain a standing grease solution; fourthly, clarifying the standing grease solution for 6-7h, and removing water and residues to obtain clean grease solution; finally, distilling the clean grease solution in a distilling pot, recycling the turpentine to obtain the finished rosin. The method is simple in process steps, low in production cost and high in recycling rate.
Description
Technical field
The present invention relates to waste reclaimation technical field, especially relate to a kind of method reclaiming rosin in waste rosin liquid.
Background technology
Rosin take pine resin as raw material, and the nonvolatile resin obtained by different processing modes is important industrial chemicals, is widely used in the industries such as soap, papermaking, paint, rubber.Rosin is divided into gum resin, wood rosin, starex 3 kinds by its source.Gum resin also claims to loosen perfume (or spice), of light color, and acid number is large, and softening temperature is high; Wood rosin is also known as steam distilled rosin, and quality is not as gum resin, and color is dark, and acid number is little, and easily crystallization from some solvent; Starex is also known as toll oil rosin.Rosin is the solid natural resin of two kinds of transparent, fragility, is the mixture of more complicated, is made up of resinous acid (abietic acid, pimaric acid), a small amount of lipid acid, rosin acid anhydrides and neutrals etc.
The working method of rosin mainly contains steaming process and method of dripping.Wherein, method of dripping is placed directly in rosin in still pot, in still-process exactly, in order to reduce distillation temperature, when rosin is heated to certain temperature, appropriate clear water must be instilled, to reduce distillation temperature, and turps and steam are together steamed, be separated and obtain turps.Rosin in pot is taken out, after filtering and impurity removing, packs to obtain rosin.The method investment is little, and technical requirements is low.But temperature is wayward, poor product quality.And steaming process is for thermal source with the steam of steam boiler generation, first by rosin heating for dissolving, leach oarse-grained impurity, then remove tiny impurity and most of moisture further by the method for precipitation, finally clean fat liquid is heated in still pot and steam turps, obtain rosin.The rosin quality that the method is produced is stable not, and complex operation.And no matter adopt the method for dripping or steaming process to produce rosin, a large amount of waste liquids and waste residue all can be had to discharge, not only to environment, and liquid and waste slag produced in part rosin, cause the waste of resource.
Summary of the invention
In view of this, the object of this invention is to provide a kind of method reclaiming rosin in waste rosin liquid, to solve in the production process of rosin, the deficiency that the waste liquid of discharge causes the waste of environmental pollution and resource and exists.
The present invention solves the problems of the technologies described above by the following technical programs:
Reclaim a method for rosin in waste rosin liquid, comprise the following steps:

(2) filter: the lysate 80-120 object filter screen obtained in step (1) is filtered to get filtrate;
(3) leave standstill: the filtrate obtained in step (2) is placed in standing pot, after leaving standstill 45-55min, obtain standing fat liquid;
(4) clarify: standing fat liquid step (3) obtained is placed in the clarifying kettle group of series connection, after clarification 6-7h, removing moisture and slag thing, obtain clean fat liquid;
(5) distill: the clean fat liquid obtained in step (4) is placed in still pot, regulate temperature to be 140-150 DEG C and carry out fore-distillation, time is 20-30min, then by time temperature be adjusted to 190-200 DEG C and carry out second distillation, time is 15-20min, reclaim turps, the raffinate in still pot obtains rosin finished product after cooling.
Further, in described step (1), by waste rosin liquid, water, oxalic acid and turps according to after the weight ratio mixing of 525:200:420:2, being heated to temperature is 160 DEG C, and constant temperature obtains lysate after keeping 14min.
Further, in described step (2), the fineness of filter screen is 100 orders.
Further, in described step (3), time of repose is 50min.
Further, in described step (4), settling time is 6.5h.
Further, in described step (5), fore-distillation temperature is 145 DEG C, and the time is 25min, and second distillation temperature is 195 DEG C, and the time is 17min.
Beneficial effect of the present invention is: processing step of the present invention is simple, and production cost is low, and the rate of recovery is high.
