| titleOfInvention | Method of extraction of reaction wood and - or normal wood out of nonstandard large wood chips |
| abstract | FIELD: pulp and paper industry. n SUBSTANCE: the invention presents a method of extraction of a reaction wood and-or normal wood from a nonstandard large wood chips and is intended for use in a pulp and paper industry. The invention provides for reduction of the nonstandard large wood chips to small-sized chips, their exsiccation with following mixture with water. Then the small-sized wood chips containing high density of extractive substances and having a high specific weight are settling. The settled small-sized wood chips are extracted for excretion of valuable extractive substances, in particular, lignites. The more light-weight small-sized chips floated on water surface are removed to return the normal timber for production of a paper stuff. The invention ensures a simple and economically efficient method of concentration of a gnarled timber material and-or normal timber out of a nonstandard large-scale wood chips. At that the process of concentration is so effective, that makes it economically expedient to recover the extractive substances from it. n EFFECT: the invention ensures a simple and economically efficient concentration of a gnarled and normal timber material out of a nonstandard large-scale wood chips. n 8 cl, 1 dwg, 1 tbl, 3 ex |
