Description
Technical field
The utility model discloses a kind of for the wet end scavenger system on the multi-cylinder long mesh paper machine, belong to the accessory on the multi-cylinder long mesh paper machine, be suitable for the cleaning to the multi-cylinder long mesh paper machine forming net, be particularly suitable for the cleaning of active calcium silicate as the multi-cylinder long mesh paper machine forming net of papermaking filler.
Background technology
Paper-making industry is that China Today (also being the world) consumes also one of large industry of the large and actual demand amount of Environmental costs, although Internet technology is advanced by leaps and bounds, but along with the develop rapidly of China's economic and global economy continue advance, China and the world do not change the aggregate demand of paper product, also slightly increase, demand to paper product, mean the demand to paper making pulps, and the forest growth rate of preparation paper making pulps is far below the requirement consumes speed of paper making pulps, under the constant prerequisite of paper products total output, how reducing the paper making pulps consumption, and can produce high-quality paper, has been that one global problem pendulum is in face of the mankind.
Untie early this road difficult problem, significant to China.At present, the most of dependence on import of China's paper making pulps, the import pulp amount has leapt to the first in the world, from strategic angle, the papermaking of China " with slurry " is in fact the use of " limited ", if world's wood pulp supply chain supply shortage in a day is arranged, China will be in the face of fearful " with slurry " exhausted problem, it is stable directly to threaten national security, the forest reserves of China are very limited, be difficult to the own paper product of reply and supply with, the China that does not analyze first today here is one of paper product state in short supply of maximum in the world still.
Based on above-mentioned, people are studying always and are seeking high filler paper production technology and production equipment thereof, untie early an above-mentioned difficult problem with it.
Paper machine is the equipment of uniting of paper making, and traditional paper machine mainly contains three types: long mesh paper making machine, cylinder mould machine, foudrinier.Wherein long mesh paper making machine is a kind of widely used paper machine type, and most paper grades of can manufacturing paper with pulp is the mainstream model of paper machine.
In the long mesh paper making machine paper-making process, paper stock is in the web part of paper machine dehydration, fiber in the paper stock and non-fibrous additive matter etc. progressively are deposited on the net, therefore require the paper stock should Uniform Dispersion on the net, make the full width page quantitatively, the uniformities such as thickness, evenness, lay the first stone for forming a second best in quality wet web;
This will ask forming net to keep clean, to satisfy the paper production needs; But present high filler (as: calcium silicates) paper pulp is when traditional multi-cylinder long mesh paper machine carries out long-term production, and traditional wet end scavenger system can not satisfy the forming net cleaning requirement, exists following problem:
Because characteristics such as high filler paper pulp filler adding proportion are high, filler is loose porous and hydrophily is strong, the drainability of paper pulp is relatively poor, and traditional wet end scavenger system can not in high filler pulp production, totally clean forming net; Long-time running, the cumulative effect because mesh stops up can't satisfy the dehydration requirement of high filler paper pulp, causes high filler paper degree of dehydration not enough, and it is relatively poor to cause simultaneously wet web to be shaped, so that can't produce satisfactory high filler paper.
How solving the problem that conventional paper machines wet end scavenger system exists, is one of people's important step of successfully developing high filler paper paper machine, is people's problems in the urgent need to address.
