Description
Technical Field
The invention relates to the technical field of pulping, in particular to a dry paper pulp production line.
Background
As is well known, China is a large paper-making country, the total output of various papers and paperboards exceeds 7350 ten thousand tons all the year round, and the total output of various fiber resources required in the year exceeds 7000 thousand tons; however, China is also a country with forest resource shortage, and the fiber resource for papermaking is extremely deficient. In order to meet the demand of paper making, more than 2000 ten thousand tons of waste paper and more than 800 ten thousand tons of primary wood pulp need to be imported in China every year. However, with the strictest environmental protection law promulgated in the recent years in China, particularly in the beginning of the 1 month of 2019, China starts a 'forbidden waste order' comprehensively, and the starting of the 'forbidden waste order' represents that 24 kinds of polluting solid wastes including paper product wastes are forbidden to be imported from abroad in China, so that a large amount of foreign waste paper cannot enter the domestic market through customs, but simultaneously, the domestic demand of huge waste paper pulp is met, and the price of the paper pulp is high. The fundamental reason why foreign waste paper cannot enter China is that a large amount of other garbage is mixed in the waste paper, the waste paper cannot pass customs inspection, and how to process the waste paper to meet the requirements of customs clearance in China is a problem which is urgently needed to be solved at present.
In the waste paper pulping process in the prior art, the process design is complex, and the equipment configuration is various. It is common to configure one complete LOCC process line and one complete AOCC process line. The LOCC processing line comprises a waste paper disintegration line, a high-concentration slag removal line, a coarse screen line, a primary grading line, a secondary grading line and a long, medium and short fiber processing line; the AOCC treatment line comprises a waste paper crushing line, a high-concentration slag removing line, a coarse screening line, a primary grading line and a long and short fiber treatment line; wherein the long, medium and short fiber treatment line comprises the working procedures of low-concentration desanding, fine screening, multi-disc concentration, heat dispersion, disc grinding and pulping and the like. When full LOCC production is adopted, AOCC production line equipment is idle and not utilized; when the AOCC and LOCC mixed production is adopted, the LOCC production line is in non-full-load production, the actual production capacity of the LOCC line is the production capacity obtained by deducting the design production capacity of the AOCC line from the design production capacity of the LOCC line, and the utilization rate of the equipment capacity is low.
In view of this, there is a need to improve the waste paper pulping process in the prior art, reduce the restrictions on production equipment and production sites, and also be beneficial to environmental protection, reduce the generation of sewage and waste gas, and make the produced paper pulp meet the requirements of customs clearance in China.
