Abstract
The invention discloses a white water processing technology of a papermaking machine, wherein collected white water of the papermaking machine is treated by flocculation and inorganic membrane filtration to obtain clean water; and then coarse cotton cloth is cleaned by the clean water. According to the technology disclosed by the invention, the problem about reuse of the papermaking machine white water is thoroughly solved; and thanks to the water collected after the flocculation, a paper pulp obtaining rate is increased and a closed cycle of the papermaking machine white water is also guaranteed.
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, the paper machine plain boiled water New Process for Treatment of the closed circulation that provide and a kind ofly namely improve paper pulp yield, in turn ensure that 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 treatment process, the paper machine white water after collection obtains clear water through flocculation, inorganic membrane filtration, then uses clean water felt.
Specifically comprise the steps:
1) paper machine white water after collecting is delivered to flocculation sedimentation system and carries out 2 flocculations, and reclaim flocculate, clear water is recycled to collecting pit.
2) the water part in collecting pit is directly used in cleaning forming web, equipment seal water system;
3) another part water inorganic membrane filtration in collecting pit, the water after filtration is stored in clear water reserviors, for cleaning the high and low hydraulic water position of felt;
4) flocculate collected is delivered to approach system.
Preferably, the flocculant in described step 1) is inorganic flocculating agent.
Preferred further, described flocculant is modification infusorial earth.Found the comprehensive Products Co., Ltd of big diatomite by Bai Shan to produce, name of product: modification infusorial earth water purification agent.
Preferably, what often purify 1 ton of water uses flocculant 1kg.
Preferably, the order number of described flocculant is 300-350 order.Order number is higher, and particle is less, when the order number of flocculant is 300-350 order, gets back to approach system to paper without impact.
Inoranic membrane in described step 3) is fired by diatomite and is formed, pore size filter 5-30um.
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 treatment process, comprises the steps:
1) paper machine white water after collecting is delivered to flocculation sedimentation system and carries out 2 flocculations, and flocculant is inorganic flocculating agent (modification infusorial earth), consumption 0.1%, and order number is 300-350 order.Reclaim flocculate, clear water is recycled to collecting pit.
2) places such as the water part 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 with the water cleaning of 2 flocculations.
3) another part water inorganic membrane filtration (modification infusorial earth is fired) in collecting pit, the water after filtration is stored in clear water reserviors for cleaning the high and low hydraulic water of felt.
4) flocculate collected is delivered to approach system, namely improves 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.
