| titleOfInvention | Method and apparatus for washing cellulosic pulp |
| abstract | A pulp washer for washing cellulosic pulp stock. The pulp washer includes an endless porous moving belt (33) that rides on a perforated rigid support plate (17) and the cellulosic stock is fed as a layer or mat (69) onto the upper surface of the belt (33). The mat is progressively reduced in thickness and liquor is extracted from the mat as it moves through the converging path. The mat is then passed through a series of conditioning or washing stations where the mat is subjected to dilution by washing and drainage cycles. Each washing station includes a standpipe (103) that extends upwardly beyond the belt and contains a wash liquid. The upper surface of liquid in the standpipe is exposed to a gas (106), such as air, so that the pressure head of the liquid in the standpipe will drive the liquid through the mat. |
