Description
Technical field
The invention belongs to drier device technical field, more particularly to a kind of energy-conservation paper grade (stock) drier device.
Background technology
China's paper industry is in a fast growth phase.Statistics over the years shows, China's paper and cardboard it is total
Yield is significantly less than aggregate consumption always, and year, paper consumption figure was horizontal far below World Developed Countries per capita.In processing manufacturing industry
Production capacity is universal superfluous at this stage, paper-making industry be demands few in number constantly increase and supply falls short of demand industry it
One, belong to typical demand pull type industry.
In decades after founding of New, the basicly stable development of China's paper industry market supply and demand.But from 20th century 90
After mid-nineties 90, there occurs great changes, the growth of domestic paper production amount to be significantly less than for domestic paper industry relation between market supply and demand
The growth of consumption figure.Due to the adjustment of consumption structure, those expensive goods critical shortages using wood pulp as raw material, have to every year
By being solved from external a large amount of imports.With the growth of economy, relatively small domestic paper and the cardboard market of scale should at present
There is the space further increased.
Paper for daily use is one of articles for daily use close with Consumer relationships.The consumption figure of paper for daily use and economic development speed
Degree, living standards of the people and civilization degree have direct relation.China has become world's second largest paper for daily use consumption market, only
Inferior to the U.S..Paper for daily use turns into the huge consumption market in one, China.
At present, the development trend of China's paper industry market structure：
It is 1. intensive
Government should encourage Chinese papermaking enterprise to run business big and strong, and develop to scale, intensive management direction, while by closing, stopping,
And, turn, the mode such as recombination and integration, with serious pollution small paper mill is cleaned out, develops surging enterprise group, is in paper industry
Realize that recycling economy creates conditions comprehensively.Meanwhile big enterprise group is also only formed, run in scale, could will be more
Fund input to environmental protection, so as to efficiently solve the problem of environmental pollution of paper-making industry.
It is 2. superior
One of distinguishing feature of life in China paper market at present, it is unbalanced exactly to consume breed structure.Statistical analysis is given birth to
Apply flexibly in paper, lavatory accounts for 56% with toilet paper, and tissue, tissue account for 21%, and paper towel and paper napkin account for 12% and 4% respectively.But number
According to display, tissue, tissue, 0.2% is only accounted for, 1.5% is only accounted for even in the city that Beijing, Shanghai are so expected,
That is the lavatory of China still occupies absolute predominance with toilet paper sale ratio.In a period of time from now on, China's paper for daily use disappears
Diversification will be presented and to medium and high-grade goods transition by taking demand.
3. integrated timber-paper
China's paper industry is going into the critical period that core is adjusted to raw material structure.After China's accession to WTO
The Anti-dumping initiated for external paper industry product import, firm International Paper giant carry out that " woods starches paper one in China energetically
The Industry Model of body ".Solves forest resourceies problem in short supply, China must rely on the policy for greatly developing artificial forest, adjustment production
Industry is laid out.Implement " forestry-pulp-paper integration " policy, encourage domestic papermaking enterprise to build fast-growing and high-yielding plantation forest energetically, it is progressively real
Existing " self-sufficient ".
4. diversification
Due to the continuous extension of paper application, paper products market comsupton is to development in pluralism.Enterprise is in order to preferably supporting simultaneously
Imperial market risk, product structure also become more diversified.
Cylinder iron drying cylinder is used as the type III pressure vessel of critical component-I that paper is dried to paper machine.The quantity of cast iron dryer is about
Account for the 2/3 of paper industry pressure vessel sum.The material for manufacturing drying cylinder is typically mostly HT200, HT250.Will on workmanship
Ask mustn't have penetrate with excessive sand holes, in order to increase paper smoothness, it is desirable to drying cylinder outer surface polish and inner surface Xuan
Light, whole cylinder wall is set to keep thickness consistent, to ensure that the safety of drying cylinder, balance and heat transfer everywhere are uniform.The effect of drying cylinder is
For drying the moisture in page, ornamenting paper.
Drying cylinder prevailing operating state is：Logical steam is needed in drying cylinder, while internal condensed water needs to eject.But drying cylinder
It is the cylinder body of a rotation, so needing special joint to complete this task, i.e. steam joint.It is passed through steam and discharge condenses
Water is typically completed together by a swivel joint in one end of drying cylinder, can also one end be passed through steam, one end discharge condensed water.Dry
Logical steam is needed in cylinder, while internal condensed water needs to eject.But drying cylinder is the cylinder body of a rotation, so needing special
Joint complete this task, i.e. steam joint.Steam and discharge condensed water are passed through typically by a swivel joint in drying cylinder
One end is completed together, can also one end be passed through steam, one end discharge condensed water.
Drying cylinder has the hollow cylinder of lid using castiron both ends, is made up of the cylinder cap at cylinder body and its both ends, external diameter is more
For between 1000mm to 3000mm, in operation process, by being passed through vapours into cylinder body, the heat transfer of vapours is to cylinder
Wall, dries the paper of conveying with this device of hot light, the cast iron that drying cylinder uses mustn't be penetrated on workmanship with it is excessive
Sand holes, it is desirable to the polishing of the outer surface of drying cylinder and by inner surface Xuan light to ensure the smooth of paper, at present, the drying cylinder of in the market
