A hard fiber aging system and pulping method thereof

Abstract

The invention relates to the technical field of pulping and papermaking, in particular to a hard fiber aging treatment system and a pulping method thereof. The aging treatment system of the present invention includes a raw material storage device, a first aging device, a fiber separation device, The refining device and the pulp recovery device also include a second aging device, the first curing device is set as a square structure with a cavity inside, and the cross-sectional shape of the first curing device is a right-angled trapezoid with a wide top and a narrow bottom. The invention is equipped with two curing devices, which facilitate better curing of raw materials and subsequent fiber separation. At the same time, by prolonging the curing time, the use of liquid medicine can be reduced, thereby achieving the effect of environmental protection. The pulping method of the present invention includes Material storage, soaking and ripening, vacuum environment ripening, fiber splitting, extruding and separating liquid medicine and pulp collection process are simple and convenient for industrial production. At the same time, the pulping method of the present invention adopts soaking and ripening, which saves cost and is friendly to the environment.

Description

technical field [0001] The invention relates to the technical field of pulping and papermaking, in particular to a hard fiber aging system and a pulping method thereof. Background technique [0002] The development of my country's paper industry is closely related to the development of the national economy and society. Economic development will provide strong support for the development of my country's paper industry, but my country's paper industry is also facing the problems of resource shortage and increasing pressure on environmental protection. my country is the world's largest importer of virgin pulp and waste paper. The supply and price of fiber raw materials in the world will definitely affect the development of my country's paper industry to a considerable extent. Scientific and rational utilization of non-wood fibers is an urgent task for the development of my country's paper industry. [0003] Oil palm is mainly distributed in the vast area at 37° north and south ...
