METHOD FOR IMPREGNATION OF PAPER RAW MATERIALS, METHOD FOR RECOVERY OF CELLULOSE FIBER FROM WASTE PAPER BALES, DEVICE FOR PRODUCTION OF CELLULOSE FIBER IN FORM OF SUSPENSION FROM WASTES CONTAINING PAPER WASTES, DEVICE FOR WASTING IMPREGNATION OF MATERIAL CONTAINING CELLULOSE FIBERS

摘要

FIELD: methods and devices for processing waste paper and cellulose fibers. SUBSTANCE: method and device for impregnation of waste paper in bales with liquid causing softening and swelling of fibers comprise the initial process of repeated use of waste paper for production of paper providing for recovery of cellulose from paper wastes. Paper wastes in form of bales are placed inside the working chamber. The chamber is closed and air is evacuated from it to create vacuum. This is followed by introduction of liquid promoting softening of fibers and their separation from the other fibers. The liquid impregnates bale paper wastes. Provision is made for exposure of fibrous material to action of liquid for the time sufficient for swelling of cellulose fibers to the extent when fibers loss their bond with other fibers and impurities. Upon expiration of the preset time, the bale is acted upon with water for rinsing out separated cellulose fibers. Obtained suspension is withdrawn from the working chamber and directed for further processing. EFFECT: higher efficiency.
