Abstract
The invention discloses an environmental-protection bio-enzyme explosion pulping method. The method comprises the following steps: cutting a grass raw material into segments, removing dust, impregnating with water, and adding catalase accounting for 20-40 wt% of the raw material; after 40-60 minutes, conveying the mixture into an explosion device, and meanwhile, adding oxydol with the concentration of 50-60% into the explosion device; and exploding to obtain the pulp. The pulping method does not generate black liquor or pollute the environment. The pulping method requires a short production cycle and does not need cooking, thereby reducing the energy consumption. The pulping yield is high and can reach above 80%. The produced pulp has the advantages of favorable physical properties and bleaching properties, and can be used for producing high-whiteness high-strength high-grade paper sheets.
Description
Technical field
The present invention relates to a kind of method of slurrying, relate in particular to a kind of environmental-protection bio-enzyme explosion pulping method.
Background technology
Grass as raw material as wheat straw, is the main raw material(s) of China's paper industry, and it is raw-material more than 50% to account for China's paper industry, wherein is mainly used to produce chemical pulp again.But adopt the traditional chemical pulping process, as soda processes, sulfate process etc., produce careless class chemical pulp, a large amount of black liquor of Chan Shenging in process of production, owing to have characteristics such as viscosity height, content of organics is low, silicone content is high, calorific value is low, cause being difficult to reclaim effectively, caused the serious environmental pollution problem.Will thoroughly solve the paper waste pollution problem, must be prevented and treated from the source, the bio-pulping technology is considered to one of effective way of head it off.A large amount of studies show that both at home and abroad, raw material through biological treatment after, chemicals consumption in the time of can reducing boiling, thereby reduced the pollutional load of black liquor.The prior biological pulping technique all is to adopt microorganism directly to handle raw material, and major defect has: the biological treatment cycle is long, generally needs several days time; Before microbiological treatment, generally tackle raw material and carry out sterilization treatment, increased production cost, might reduce the quality of raw material simultaneously; Problems such as biological treatment process is difficult to effective control, and the quality uniformity that raw materials treated usually occurs is poor, and carbohydrate degradation is serious cause pulping yield to reduce; Pulp quality is compared with chemical pulp, and physical property and bleachability are all relatively poor, can not be used for producing high whiteness, high-intensity paper, can only be used for producing low-grade product, can't satisfy the needs of high-grade product to pulp quality.
Summary of the invention
The object of the present invention is to provide a kind of environmental-protection bio-enzyme explosion pulping method, to solve a normal above-mentioned difficult problem that occurs in the existing biological pulping method, effectively reducing on the basis of pulping waste liquor pollution the grass as raw material bleached pulp of producing high whiteness and having the higher-strength performance.
The objective of the invention is to be achieved through the following technical solutions, grass as raw material is carried out segment, after the dedusting, use water saturates, add the catalase that accounts for raw material weight 20% to 40%, after 40 to 60 minutes, be delivered in the quick-fried device of spray, in the quick-fried device of spray, add simultaneously concentration and be 50% to 60% hydrogen peroxide, through spray quick-fried after pulp, can obtain white slurry.
Hydrogen peroxide has the effect of bleaching to paper pulp, sprays in the quick-fried process in the quick-fried device of spray and bleaches, and catalase decomposes remaining hydrogen peroxide, prevents that raw material and paper pulp are excessively oxidated.
The present invention compares with existing paper pulp manufacture craft and has the following advantages: do not produce black liquor, and free from environmental pollution; With short production cycle, without boiling, reduced energy resource consumption; The pulping yield height can reach more than 80%; Paper pulp physical property and the bleachability produced are all better, can be used for producing high whiteness, high-intensity higher class paper.
The quick-fried device of spray of the present invention is a prior art.
The specific embodiment
Embodiment 1:
Raw material is a wheat straw, carries out segment, after the dedusting, uses water saturates, add the catalase that accounts for raw material weight 20%, after 60 minutes, be delivered in the quick-fried device of spray, in the quick-fried device of spray, add simultaneously concentration and be 50% hydrogen peroxide, through spray quick-fried after pulp, can obtain white slurry.
Embodiment 2:
Raw material is a wheat straw, carries out segment, after the dedusting, uses water saturates, add the catalase that accounts for raw material weight 40%, after 40 minutes, be delivered in the quick-fried device of spray, in the quick-fried device of spray, add simultaneously concentration and be 60% hydrogen peroxide, through spray quick-fried after pulp, can obtain white slurry.
Claims (1)
1. environmental-protection bio-enzyme explosion pulping method, it is characterized in that it may further comprise the steps: grass as raw material is carried out segment, after the dedusting, use water saturates, add the catalase that accounts for raw material weight 20% to 40%, after 40 to 60 minutes, be delivered in the quick-fried device of spray, in the quick-fried device of spray, add simultaneously concentration and be 50% to 60% hydrogen peroxide, through spray quick-fried after pulp.
