Title (EN) CONDITIONING BALES OF WASTE PAPER FOR RECYCLING
(FR) CONDITIONNEMENT DE BALLES DE VIEUX PAPIERS EN VUE DE LEUR RECYCLAGE
Abstract:
(EN) Waste paper material packaged in compressed bale form (10) is sufficiently wetted with a liquid such that waste paper cellulosic fibers will soften and swell prior to the waste material being subjected to the recycling pulping operation. A cellulosic fiber softening and swell-inducing liquid is injected (12) at high velocities into the interior of each unbroken bale by bringing a jet establishing nozzle assembly connected to a high pressure source of the liquid into close adjacency with one or more exterior surfaces of the bale and discharging liquid from the nozzle assembly into the bale waste material for a predetermined time sufficient to wet the waste material, after which time the material in the wetted bale is allowed to sorb the fluid for a period as will result in cellulosic fibers in the waste material softening and swelling a substantial degree before the waste material is introduced into the recycling pulper (11).
(FR) La matière de vieux papiers emballés et comprimés sous forme de balles (10) est suffisamment mouillée avec un liquide de façon que les fibres de cellulose des vieux papiers se ramollissent et gonflent avant que les vieux papiers soient soumis à l'opération de réduction en pâte et de recyclage. Un liquide servant à ramollir et à gonfler les fibres de cellulose est injecté (12) à grande vitesse à l'intérieur de chaque balle non défaite en plaçant un ensemble à ajutages de projection d'un jet connecté à une source du liquide sous haute pression très près d'une ou de plusieurs surfaces extérieures de la balle et en déversant le liquide projeté par l'ensemble à ajutages dans la matière de rebut de la balle pendant une durée prédéterminée suffisante pour mouiller la matière de rebut. On laisse ensuite la matière mouillée de la balle absorber le liquide pendant un certain temps pour que les fibres de cellulose de la matière de rebut se ramollissent et gonflent sensiblement. La matière de recyclage est alors introduite dans le désintégrateur de pâte à papier de recyclage (11).
