Abstract
The invention discloses a circulating reuse method for white water in a paper machine. The collected white water in a paper machine is divided into two portions after being filtering by a microfiltration machine, one portion is directly used for washing a moulding net, the other portion is filtered after flocculation and deposition to become clean water which is used for washing felts. The invention thoroughly solve the reuse technical issue for the white water in the paper machine, water is collected after flocculation, the yield of paper pulp is raised, and the white water in the paper machine can be cycled in an enclosed state.
Description
Technical field
The present invention relates to a kind of paper machine plain boiled water New Process for Treatment.
Background technology
As everyone knows, can recycle with water in paper-making process, the target of zero-emission can be reached, depend on that paper machine plain boiled water can closed circulation to a great extent.The paper machine white water in paper mill in the past, a part of papermaking enterprise is with after many disk filtration, and a small amount of water is used for washing the positions such as net, can not clean felt, and a large amount of water still will get back to middle section water process; The paper machine white water of most of papermaking enterprise directly enters middle section water treatment system, is a kind of waste, turn increases the running cost of water treatment.The main cause that paper machine plain boiled water can not recycle is, the water after simple process cannot be used for cleaning felt.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing defect, provides a kind of new technology of reuse problem of thorough solution paper machine white water.
Object of the present invention carrys out specific implementation by the following technical programs:
A kind of paper machine plain boiled water circulation reusing technology, the paper machine white water after collection is after Microfilter filters, and point two parts, a part is directly used in cleaning forming web, and a part to carry out after flocculation sediment more after filtration, forming clear water, for cleaning felt.
Preferably, above-mentioned technique, comprises the steps:
1) paper machine white water after collecting is delivered to drum type brake Microfilter and filters, and reclaim fiber fines, the water after filtration is stored in collecting pit;
2) the water part in collecting pit is directly used in cleaning forming web, and as equipment sealing system water (because forming web is 90 object polyester webs, the water cleaning after filtering with Microfilter (Microfilter is drum type brake woollen goods net filtration machine) does not exist any problem);
3) after the first flocculation sediment of another part water in collecting pit, then filter through ultra filtration machine (for the PETAXTM fine filtration system that Kadant Johnson Inc. provides), be stored in clear water reserviors and use as the high and low hydraulic water of cleaning felt;
4) collect flocculate and be delivered to approach system together with the fiber fines of recovery, namely improve paper pulp yield, in turn ensure that the closed circulation of paper machine white water.
Preferably, in described step 1), the order number of micro-rate machine screen pack is 150-200 order
Preferably, in described step 3), described flocculant is inorganic flocculating agent.
Preferred further, described flocculant is modification infusorial earth.Manufacturer is the comprehensive Products Co., Ltd of the big diatomite of Bai Shanli, name of product: modification infusorial earth water purification agent.
Preferred further, the order number of described modification infusorial earth is 300-350 order.
Preferred further, often purify 1 ton of water 0.6kg.
Preferably, in described step 3), described ultra filtration machine is the PETAX that Kadant Inc. produces
tMfine filter.
Beneficial effect of the present invention:
Present invention process is in order to thoroughly to solve the reuse problem of paper machine white water, and the water collected after flocculation, namely improves paper pulp yield, in turn ensure that the closed circulation of paper machine white water.Compared with prior art, mainly to have the following advantages:
1, technological process is short, need not get back to middle section water treatment system, saves running cost.
2, floor space is little, and system can build paper machine room in, saves one-time investment.
3, closed circulation is reached, for paper-making zero discharge specifies direction.
Detailed description of the invention
Below the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
embodiment 1
A kind of paper machine plain boiled water circulation reusing technology, comprises the steps:
1, the paper machine white water after collecting is delivered to drum type brake Microfilter and filters, and reclaim fiber fines, the water after filtration is stored in collecting pit.Micro-rate machine filters mesh number 150-200 order.
The places such as the water part 2, in collecting pit is directly used in cleaning forming web, equipment sealing water.Because forming web is 90 object polyester webs, there is not any problem in the water cleaning after filtering with Microfilter.
3, after the first flocculation sediment of another part water in collecting pit, then filtering through ultra filtration machine, being stored in clear water reserviors for cleaning the high and low hydraulic water of felt.Flocculant is inorganic flocculating agent (modification infusorial earth), consumption 0.06%, and order number is 300-350 order.Ultra filtration machine is the PETAXTM fine filter that Kadant Inc. produces.
4, collect flocculate and be delivered to approach system together with the fiber fines of recovery, namely improve paper pulp yield, in turn ensure that the closed circulation of paper machine white water.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment to invention has been detailed description, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
