Embodiment 1

[0027] Measure according to absolute dry weight, weigh 2000kg of wood distiller's grains, and proceed according to the following steps:

[0028] Crushing and removing slag: Send wood distiller's grains or potato distiller's grains into a crusher to crush them into fine particles, and then sieve to remove coarse dregs:

[0029] Cooking: the material after the coarse slag is removed in the step of crushing and removing slag is sent into a digester, and heated and cooked for 3 hours under a steam pressure of 0.3Mpa to make a cooked slurry;

[0030] Washing and rinsing: send the cooked pulp after cooking into the rinsing machine and repeatedly wash and rinse it three times with clear water to obtain a clean pulp after washing and rinsing;

[0031] Concentration and dehydration: Send the washed and rinsed slurry to the thickener for dehydration and concentration operation, and then the wood-based distillers grain fiber pulp product that has been dehydrated into an air-dried slurry ...

Embodiment 2

[0036] 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 put 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.

[0037] It is also possible to input the prepared paper-making slurry into the scoop tank, and use the traditio...

Embodiment 3

[0039] 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 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.

[0040]The prepared paper-making slurry can also be input into the scoop tank, and the traditional manual scooping method can be used to make handmade pap...

Abstract

The invention provides a papermaking method by using vinasse fiber pulp. The method is characterized in that the disposal vinasse from the alcohol industry is regarded as raw material, the vinasse fiber pulp mainly containing the cellulose and hemicellulose used for papermaking is prepared through the steps of crushing and slag-removing, boiling, washing and rinsing and the like, the vinasse fiberpulp is mixed with the papermaking slurry prepared by the conventional paper raw material composed of wood, bamboo wood, rice straw, straw, reed, recovery waste paper and the like to prepare mixing papermaking slurry, the mixing papermaking slurry is sent to the paper machine to produce products, or the method that the vinasse fiber pulp is prepared by the vinasse as raw material and after dilution pulping, water distribution and slurry mixing the vinasse fibre pulp is sent to the paper machine to produce paper products is completely adopted. The raw material field of papermaking industry isdeveloped, the cost of papermaking production is greatly reduced, the austere problem that the environment pollution nuisance is caused by a lot of vinasse disposed from the alcohol industry is effectively solved, the method has substantial economic benefit and social environment benefit and good popularization and use prospect.

Description

technical field [0001] The invention relates to the production technology of pulping and papermaking, in particular, the invention is a method for making paper with distiller's grain fiber pulp. Background technique [0002] At present, my country's papermaking technology is still at the middle and lower level in the world. The main reasons are: First, the energy consumption is high. One ton of pulp only consumes 20 to 60 tons of water, while my country needs 2000 to 5000 tons; second, the pollution is serious. After my country adopted measures to ban logging to protect forests, the traditional paper industry mostly used bamboo, rice straw, and reeds. 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 my country is second only to the chemical industry, and the discharge of COD in wastewat...
