Embodiment 1

[0015] 500 kilograms of pine roots are removed and pulverized (1) into 0.5 cm small wood chips, then put into the soaking tank (2) and soaked for 2 hours to get the clarified filtrate by suction filtration. Reciprocate three times like this again filtrate merges and injects in the distiller (3) and carries out distillation, and what remains in the soaking tank is 296 kilograms of very pure wood fibers and can be sold to paper mills etc. The distiller recovers the organic solvent through shallow distillation at 60-100 degrees and recycles it; when the temperature reaches the fraction of 100-150 degrees, 71.3 kilograms of crude turpentine can be obtained by cooling (4), and 45.7 kilograms of pure turpentine can be obtained after refining. Cut is 25.6 kilograms of pine light oil; When temperature reaches deep distillation 150-300 degree cut, obtain 44.6 kilograms of turpentine oil through cooling (5), obtain turpentine oil total quality as 70.2 kilograms with above-mentioned; Dist...

Embodiment 2

[0017] 500 kilograms of pine roots are removed and crushed into 3.5 cm small wood chips, and then put into a soaking tank to soak for 4 hours to obtain a clarified filtrate. Reciprocate three times like this again filtrate merges and injects in the distiller and carries out distillation, what remains in soaking pool is very pure wood fiber 315 kilograms and can sell to paper mill etc. The distiller undergoes shallow distillation at 60-100 degrees to recover the organic solvent and recycle it; when the temperature reaches the fraction of 100-150 degrees, 65.5 kg of crude turpentine can be obtained, and 39.9 kg of pure turpentine can be obtained after refining, and the rest is turpentine 25.6 kilograms; Obtain 38.2 kilograms of turpentine oils when temperature reaches deep distillation 150-300 degree cut, obtain turpentine oil total quality as 63.8 kilograms with above-mentioned; Distillation remaining heavy oil obtains the rosin of 70.06 kilograms through cooling.

Abstract

The invention discloses a method for abstracting series pine product and wood fiber from pine roots. The main technical proposal is as follows: after soil impurities on the pine roots are removed by pretreatment, the pine roots are crushed into small block crumbs; and then the crumbs are soaked in an organic solvent in a container for two hours, therefore, after the crumbs are soaked for three times repeatedly, pine fiber after soaking can be obtained by filtration and separation and sold to paper making factories and the like. Soaking solutions of the three times are merged and injected into a distiller for distillation separation. Firstly, the organic solvent and water flow out by light distillation; secondly, the turpentine oil crude product flows out from an initial distillation point; and then after being refined, the turpentine oil crude product becomes turpentine oil. When a final distillation point is reached, distillate becomes pine-stump light oil crude product by cooling; and after being refined, the pine-stump light oil crude product can be used as fuel oil; finally, the remained flows out and cooled, and then maroon and transparent wood rosin is obtained. The implementation of the method not only cleans the pine roots of pine oil pollution in forests of mountains, but also lowers the manufacture cost, thus leading forest chemical to develop a new industrial path.

Description

Technical field: [0001] The invention relates to the technical field of organic chemical extraction, in particular to a method for extracting pine products and wood fibers from pine roots. Background technique: [0002] At present, the production of rosin and turpentine is all made of artificially harvested natural turpentine through a series of processing and refining. Although the quality is very good, the cost is very high, and the selling price is too high, so that it has reached the level that many users are daunted. They were all looking for low-priced rosin and turpentine, so low-priced rosin and turpentine became popular. [0003] The rosin and turpentine of the present invention are good in quality, very low in cost and low in selling price, and are just catering to market demands. Moreover, the processing and utilization of this product cleans up the roots of pine trees in the mountains, avoiding the phenomenon of pine oil polluting the mountains. This is equiva...
