摘要
A continuous digester for producing chemical pulp, a process for operating the digester, the present invention relates to a feedback system for cooking liquor. By providing a fifth region cooking area with a proportion of the timber and the liquid down, decreases continuously through the digester, the first region, the second region, the third region, and the fourth region, to cook during , making it possible to obtain a more uniform alkali graph. Is 1, more than enough the proportion of timber and conventional liquid, typically 6: about 3.5 to 5.0 usually alkaline available overall, by the percentage of wood and high liquid more than enough to 1, is kept high at the beginning. When used in combination with it to return to the top of the digester, cooking liquor from the cooking area next to cooking softwood, low at the beginning of the cook, in the range of 20~35g / l, typically, the alkali concentration It can be kept. All alkali, this is achieved by that is more than 80%, is added to the beginning of the cook in nature. It is suitable for the cooking process, more uniform alkali graph results in pulp volume improved.
