Abstract

Изобретение касаетс целлюлозно-бумажного производства, в частности аппаратов дл обработки целлюлозосодержащего материала, и позвол ет интенсифицировать процесс обработки и улучшить качество конечного продукта. Пар и жидкость, поданные по патрубкам 7 и 8, проход т между стенками корпуса 1 и распределительной камеры 3, попадают в прорези 4 на поверхности камеры 3. За счет пульсационных гидродинамических воздействий, создаваемых прорез ми 4, расположенными на боковой поверхности распределительной камеры 3, происходит эффективное перемешивание и обработка целлюлозосодержащего материала тепловыми и жидкостными потоками по всему объему устройства, как в поперечном, так и в продольном направлени х. 1 ил.The invention relates to pulp and paper production, in particular apparatus for treating cellulose-containing material, and allows to intensify the process and improve the quality of the final product. Steam and liquid, fed through the pipes 7 and 8, pass between the walls of the housing 1 and the distribution chamber 3, fall into the slots 4 on the surface of the chamber 3. Due to the pulsating hydrodynamic effects created by the slots 4 located on the lateral surface of the distribution chamber 3, efficient mixing and processing of cellulose-containing material by thermal and liquid flows occurs throughout the device, both in the transverse and in the longitudinal directions. 1 il.
