Description
Technical field
The present invention relates to pulping and paper-making production technical field, particularly to a kind of OCC line slurry high efficiente callback production method.
Background technology
Modern heavy packages paper manufacturing enterprise single production base yield is increasing, and every day, OCC line produced substantial amounts of low
Dense scummer latter end tailings, fine screen latter end tailings, the total deslagging of trench plain boiled water.Production instance: daily output 5000T papermaking base produces
These three latter end tailings are oven-dry weight 350 tons every day, the lowest dense scummer latter end tailings about 170 tons, fine screen latter end tailings and
The total deslagging of trench plain boiled water about 180 tons.After the latter end tailings ash of five sections of scummer groups of traditional handicraft reaches 55～60%, it is difficult to again
Carrying out fiber recovery, paper plant's Normal practice is to send to after Double-screen filter press is pressed onto certain mass dryness fraction, and outward transport processes；Fine screen latter end tailings
And the total deslagging of trench plain boiled water is then many because of impurity content, it is impossible to efficiently separate, common practices is to burn or outward transport process.Zeng You great factory
Attempt newly-increased 6th section of low dense slagging-off at indivedual paper machines, or construction setting pot is to carry out few fibers recovery, but actual recovered effect
Rate is low, and yield is little.
During realizing the present invention, inventor finds that in prior art, there are the following problems:
1, a large amount of tailings process outward transport as solid waste, do not carry out slurry reuse, cause cost of material to rise.
2, a large amount of tailings process outward transport process as solid waste, add environmental protection treatment cost.
3, the easy device such as traditional construction setting pot carries out slurry recovery, and processing mode is simple, and efficiency is low, and treating capacity is little.
4, the easy device such as traditional construction setting pot carries out slurry recovery, and yield is low, reclaims the quantity of slag few, and benefit is low.
5, tradition slag recovery method Yield and quality is the most unstable, it is impossible to directly dexter feeder is manufactured paper with pulp.
Summary of the invention
For this reason, it may be necessary to provide a kind of OCC line slurry high efficiente callback production method, it is used for solving a large amount of tailings in large-scale paper mill
