Embodiment 1

[0026] Measure according to absolute dry weight, weigh 2000kg of wood distiller's grains, and proceed according to the following steps:

[0027] Crushing and removing slag: Send wood distiller's grains or potato distiller's grains into a pulverizer to crush to fine particles, and then screen to remove coarse dregs;

[0028] Cooking: Send the material after the coarse slag has been removed in the crushing and deslagging step into a digester, heat and cook for 3 hours under a steam pressure of 0.3Mpa, and make a cooking slurry;

[0029] Washing and rinsing: send the cooked pulp into the rinsing machine and wash and rinse it with clean water three times repeatedly to obtain the pulp that has been washed and rinsed;

[0030] Concentration and dehydration: send the washed and rinsed slurry to the thickener for dehydration and concentration operation, and then the finished wood-based distillers grain fiber pulp that has been dehydrated into an air-dried slurry state can be obtained....

Embodiment 2

[0035] Waste paper pulp produced according to the technical requirements of conventional papermaking and pulping technology, weigh 300 kg of waste paper pulp products by dry weight and put them into the beater; 1000kg is mixed into the beater, and the fibers are further bifurcated through the dilution and beating step to make a mixed papermaking slurry, that is, a mixed papermaking slurry of 1300Kg by absolute dry weight is obtained, and then according to the papermaking technology of the paper machine According to the requirements, it is sent to the pulping tank for water distribution and pulping, and is blended into a papermaking slurry that meets the technical requirements of the papermaking process, and then the prepared papermaking slurry is input into the paper machine for conventional papermaking to produce paper containing distiller's grain fiber pulp product.

[0036] The prepared paper-making slurry can also be input into the scoop tank, and the traditional manual sc...

Embodiment 3

[0038] Prepare bamboo pulp according to the technical requirements of conventional papermaking and pulping technology, and weigh 1000kg of bamboo pulp products by dry weight and put them into the beater; In the beating machine, the fibers are further bifurcated through the dilution and beating step, and the mixed papermaking slurry is made into a mixed papermaking slurry, that is, a mixed papermaking slurry of 1300Kg by absolute dry weight is obtained, and then sent according to the technical requirements of the papermaking machine. Enter the pulping tank for water distribution and pulping, blending into papermaking pulp that meets the technical requirements of the papermaking process, and then input the prepared papermaking pulp into the paper machine for conventional papermaking to produce paper products containing wood-based distillers grain fiber pulp.

[0039] The prepared paper-making slurry can also be input into the scoop tank, and the traditional manual scooping method...

Abstract

The invention relates to a lees fiber pulp and the method for producing paper with said pulp. Wherein, it uses the less generated by alcohol industry as raw material, via breaking, screening, braising, and washing, to produce the lees fiber pulp that containing the fibrin and hemicellulose; it can be mixed with the slurries made from wood, bamboo, straw, or recycled waste paper, into mixed pulp, to be fed to paper maker to produce paper; or it can only use the less as raw material to produce less fiber pulp, to be diluted and mixed with water to be fed to paper maker to produce paper. The invention enlarges the raw material resource of paper industry, reduce the producing cost of paper, and solve the problem of environment pollution.

Description

technical field [0001] The invention relates to the production technology of pulping and papermaking, in particular, the invention relates to a distiller's grain fiber pulp and a method for making paper with the distiller's grain fiber pulp. Background technique [0002] At present, China's papermaking technology is still at the middle and lower level in the world. The main reasons are: first, the high energy consumption. One ton of pulp only consumes 15 to 60 tons of water, while China needs 400 to 500 tons; second, the pollution is serious. After China took measures to ban logging to protect forests, the traditional paper industry mostly uses bamboo, rice straw, reeds and other materials. Plants are the main raw materials for papermaking, and its production scale is small. Compared with large-scale wood pulp production, its technical equipment is relatively backward. The discharge of wastewater from the papermaking industry in China is second only to the chemical industry,...
