Description
Technical field
The invention belongs to waste sludge from paper mill utilization technology fields, generate more particularly, to a kind of pair of regenerated paper making
Waste residue carries out the method and processing dedicated unit of comprehensive regeneration.
Background technique
It is not only economized on resources using regenerated paper making, but also advantageously reduces environmental pollution.But since waste paper ingredient is multiple
It is miscellaneous, it containing plurality of impurities ingredient, cannot be fully utilized, a large amount of " regenerated papermaking waste residue " can be generated in production.According to endless
Full statistics, the waste residue that recycled writing paper production in the whole nation generates at present is up to 1500~16,000,000 tons/year.These waste sludge from paper mill ingredients are very multiple
It is miscellaneous, generally containing substances such as old metal, spent high molecular material (waste plastics etc.), paper pulp, flammable bottom ash and inorganic matters.Ingredient is multiple
Miscellaneous and substantial amounts waste sludge from paper mill are always a great problem for perplexing paper-making industry development.Traditional processing mode, first is that burn,
Second is that landfill.When burning disposal, since the combustion heat value of waste residue is low, processing cost is high, and treatment process can generate dioxin, holds
Easily cause secondary pollution；Landfill disposal does not only take up a large amount of land resource, and if mishandling, will be to ecological ring
Border, which is brought, to be seriously affected.Newest processing method is that sorting and impurity elimination are carried out to waste sludge from paper mill, then to the substance isolated point
It is not utilized and is handled, to realize innoxious and resource utilization.But due to waste sludge from paper mill complicated component, substantial amounts,
The difficulty of category filter is big in actual process, at high cost, and enterprise is difficult to bear.It is the inorganic matter isolated, old metal, useless
The substances such as old macromolecule (waste plastics etc.), paper pulp, flammable bottom ash, respectively will also process it by distinct device and technique
Processing；And classification processing the problem of investing operating cost height and recontamination, it is negative to further increase enterprise there is also complex process
Load.So existing waste sludge from paper mill processing mode, not only equipment and complex process, operating cost height, enterprise are difficult to bear, and very
Difficulty meets the innoxious ecological, environmental protective target call of waste sludge from paper mill recycling.
Summary of the invention
