Abstract
The invention discloses a totally chlorine-free clean pulping method by separation and utilization of a full-stalk kenaf component, and is a pioneering invention in the field of light industry. The totally chlorine-free clean pulping method is characterized by comprising the following steps: after the full-stalk kenaf is cut into sections and thermally soaked and washed, decomposing the sections into velvet-like fibrous bundles by a thread rolling machine; feeding the velvet-like fibrous bundles into a heating reactor to dissolve hemicellulose and part of lignin; extruding the liquid from thehemicellulose and the part of lignin by a screw extruder, and drying the hemicellulose and the part of lignin to make xylan; putting the extruded crude material into a plant fiber photoelectric oxygen comprehensive generator to carry out totally chlorine-free bleaching; decomposing the cellulose by a defibering and grinding machine; and screening the cellulose to obtain required slurry by a screening machine according to a 100-mesh sieve pore, a 60-mesh sieve pore and a 20-mesh sieve pore for manufacturing high-grade paper, special paper and ordinary stationary paper so as to realize an optimized process of separation and utilization of the full-stalk kenaf component and totally chlorine-free.
Description
Technical field
The present invention is the pioneering invention of field of light industry.
Background technology
Full-stalk kenaf is used for pulping and paper-making and exists three big insoluble problems: the one, and the bar skin separates difficult, wastes bigger; The 2nd, utilize traditional pulping process mestha bar and skin to be difficult in boiling together, attend to one thing and lose sight of another; The 3rd, mestha slurrying pollutional load is heavier, is difficult to handle.
Summary of the invention
The technology of the present invention feature is with the full-stalk kenaf cutting section, segment length 5-10cm, hot dipping washing back adopts thread rolling machine to resolve into velvet shape cellulose, be delivered in the reactor heating, temperature remains on 100 ℃, starch dense 25%-30%, temperature retention time 30min, be delivered to the shove spiral after the discharging, the hemicellulose of dissolving and part lignin and water are extruded about 1-1.5 ton liquid, and (the liquid oven dry is the making xylan afterwards, the steam reuse is to reactor heating), coarse fodder behind the shove enters in the comprehensive generator of string photoelectricity oxygen (license number 200620138146.3) and carries out total chlorine free bleaching, adopt then and discongest, grinder decomposes cellulose, utilize again screening machine with cellulose by 100 mesh sieve holes, 60 mesh sieve holes, 20 mesh sieve hole sizers are selected needed slurry and are respectively applied for the high-grade paper of making, speciality paper and general culture paper reach the full-stalk kenaf combination and separate, utilize, the optimization technology of total chlorine free bleaching.
Specific implementation method: 1, full-stalk kenaf cutting section, segment length 5-10cm, hot dipping washing back adopts thread rolling machine to resolve into velvet shape cellulose.
2, cellulose is delivered in the reactor heating, temperature remains on 100 ℃, starches dense 25%-30%, temperature retention time 30min.
3, slurry is delivered to shove spiral (or press master) hemicellulose of dissolving is extruded 1-1.5 ton liquid (liquid oven dry back makes xylan, and the steam reuse is to reactor heating) with part lignin and water.
4, the coarse fodder behind the shove enters in the string photoelectricity oxygen combined reaction device and carries out total chlorine free bleaching, adopt then discongest, grinder decomposes cellulose.
5, utilize screening machine that cellulose is selected needed slurry by 100 mesh sieve holes, 60 mesh sieve holes, 20 mesh sieve hole sizers and be respectively applied for making high-grade paper (as security, coinage paper), speciality paper (as cigarette paper, tea bag paper) and common paper (as light-duty text paper, newsprint), reach the optimization technology of full-stalk kenaf combination separation, utilization, total chlorine free bleaching.
Claims (1)
1. the full-stalk kenaf component separation utilizes Totally chlorine-free clean pulping method, its major technique feature is that full-stalk kenaf is cut segment length 5-10CM, hot dipping washing back adopts thread rolling machine to resolve into velvet shape cellulose, be delivered in the reactor heating, temperature remains on 100 degrees centigrade, starch dense 25%-30%, temperature retention time 30 minutes, be delivered to the shove spiral after the discharging, with the shove spiral hemicellulose and part lignin and the water of dissolving are extruded 1-1.5 ton liquid, the oven dry back makes xylan, the steam reuse is to reactor heating, coarse fodder behind the shove adopts the comprehensive generator of string photoelectricity oxygen to carry out total chlorine free bleaching, adopt then and discongest, grinder decomposes cellulose, utilize again screening machine with cellulose by 100 mesh sieve holes, 60 mesh sieve holes, 20 mesh sieve hole sizers are selected needed slurry and are respectively applied for the high-grade paper of making, speciality paper and general culture paper, wherein said high-grade paper are loan or coinage paper.
