摘要
根据广西贺达纸业有限责任公司的实践,建议在二段升温前,由液相转为汽/液两相蒸煮,以进一步降低蒸煮能耗。系统尽可能采用加热器间接通汽的加热方式,以减少污染。根据公司具体情况,采用较低的蒸煮最高温度,较慢速升温和混合送入热黑、白液等方法,以提高纸浆的黏度。并提出一种新式U形管蒸煮加热器的结构和叙述了清洗方法。
Based on the practice at Heda Paper Co., Ltd., the proposals are that： turning liquid phase cooking to steam/liquid phase cooking before second increasing temperature, so that energy can be saved; the way of indirect heating should be used on the DDS as much as possible for decreasing pollution; suitable lower maximum cooking temperature; longer time of second increasing temperature period; and mixing hot cooking liquor （hot black liquor and hot white liquor） sent to digester as well, so that viscosity of pulp can be increased. The proposals also include construction of the new type heat exchanger and method of cleaning it.
