Description
Technical field
The present invention relates to field of papermaking, particularly relate to a kind of adding technology for biology enzyme in pulping and papermaking processes and interpolation equipment.
Background technology
China is paper industry big country, and traditional paper industry is power consumption and environmental pollution rich and influential family, and the regeneration of waste paper has become the solution paper industry important channel that there is lack of raw materials.
A large amount of reuses of secondary stock, occupy very important status in modern paper technique.At present, the output of world's secondary stock is only second to chemical pulp, 1/3rd of Yi Zhan world paper pulp total amount.But stickies problem is one of major obstacle affecting waste paper recycling in waste paper always.Sicker itself has viscosity, is usually attached together with inorganic filler, fiber fines etc. and forms viscous precipitate thing, and cause the dehydration of paper machine abnormal, air consumption increases, and disconnected paper frequently waits and produces extremely, has a strong impact on paper making process.Because short fiber does not have heat partition, the sicker in slurry cannot be processed.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of adding technology for biology enzyme in pulping and papermaking processes and interpolation equipment, can sicker in efficient degradation slurrying system and other colloid fecal material, the sicker of tiny, particulate or rubbish are cleared out effectively, effectively reduces sicker paper feeding machine and run the puzzlement brought.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of adding technology for biology enzyme in pulping and papermaking processes, described pulping process comprises: size degradation, slagging-off, concentrated, slagging-off, squeezing, dry, press polish, batch and rewinding process, described concentration technology comprises: long fine concentration technology and short fiber concentration technology, bio-enzyme degradation operation is added in described short fiber concentration technology, described bio-enzyme degradation operation adopts adds biology enzyme in short fiber concentration technology, addition mode is from less to more adopted when adding biology enzyme, the addition of described biology enzyme is 0.05kg/t ~ 0.15kg/t, react 1 ~ 2 hour after with the addition of this biology enzyme.
Preferably, described biology enzyme adopts the one in cellulase, hemicellulase, lignin degradation enzyme, amylase, lipase, pectase, esterase, laccase.
Invention also improves a kind of interpolation equipment for biology enzyme in pulping and papermaking processes, comprising: biology enzyme bucket, carrier pipe, compression pump and thickener, described biology enzyme bucket is connected to thickener by carrier pipe, arranges compression pump at described carrier pipe place.
Preferably, described thickener is polydisc thickener.
Preferably, also electromagnetic valve is provided with between described compression pump and biology enzyme bucket.
The invention has the beneficial effects as follows: 1, can sicker in efficient degradation slurrying system and other colloid fecal material, the sicker of tiny, particulate or rubbish are cleared out effectively, effectively reduces sicker paper feeding machine and run the puzzlement brought; 2, technology and equipment is simple, only need change and add a small amount of equipment, just can complete the interpolation of biology enzyme; 3, energy consumption is low, and paper pulp yield is high, uses biology enzyme slurrying, significantly can reduce energy consumption, improves paper pulp yield; 4, and chemicals need not be used less, easy, safe, environmentally friendly, adopt free of contamination biology enzyme, alleviate the load of enterprise to wastewater treatment.
