PRODUCTION METHODS OF RECLAIMED PULP, METHODS OF SURFACE MODIFICATION OF BODY STOCK FIBER AND ADMIXTURES AS WELL AS DEVICE FOR PRODUCTION OF PULP

摘要

FIELD: textile; paper.;SUBSTANCE: device is intended for use in paper-and-pulp industry. The production method of reclaimed pulp consists in that bulbs are generated by cavitating using fluid jet and contact with pulp suspension when reclaiming waste paper for separation of contamination applied on the fibers of pulp and nonorganic particles. The apparatus for production of pulp consists of a tank, one or more jet pipes for discharging under pressure liquid into material containing fibers of pulp in the tank. The apparatus contains a pressure control mechanism placed higher along the current from the jet pipe, pump placed higher along the current from the pressure control mechanism.;EFFECT: production of high quality pulp is ensured.;23 cl, 16 dwg, 5 tbl, 20 ex
