Description
Technical field
This patent is related to the filtration arts such as industry, papermaking, and in particular to the mthod of white water from paper making recovery filter disc with metallic fiber.
Background technology
Contain substantial amounts of fiber fines and chemical residues thing in traditional paper-making process in caused plain boiled water, enterprise is discharging
Spend substantial amounts of fund to carry out slurry recovery and sewage disposal on sewage, be all huge consuming in financial resources, material resources.Make at present
More disk fibre recovery machines that paper enterprise uses carry out the recycling of fiber in paper-making white water and water.More disk fiber recoveries
Machine is separated the fiber in plain boiled water and water by separating and filtering technology, White Water Treatment by fiber cushion by it is thin to
Thickness produces the filtered fluid of three kinds of different clean levels, respectively turbid filtrate, clear filtrate, super clear filtrate, and turbid filtrate is used for slurrying
Workshop section；Clear filtrate is used for the sealing water for ensureing paper machine pulping equipment；Super clear filtrate is used for the normal pressure of paper machine, high-pressure wash；And divide
Separate out the secondary use that the fiber come is used for papermaking.By this process, it is big to solve traditional paper grade (stock) water, water process expense
The problem of high, reach environment-protecting clean production.
More disk fibre recovery machine filter discs on the market at present.The polyester mesh bag woven using polyester material, but using
In there is following drawback：Polyester material mesh bag is to be wrapped by heat shrink on filter disc, because of its material reason, is easily caused poly-
Ester mesh shrinks uneven, mesh cause problem not of uniform size, poor so as to filtering accuracy occur；And the installation side tightened up using heat
Method can also make polyester mesh bag bulge occur, fall the problems such as slurry, water filtering performance decrease, filtering water difference.Polyester webs are in long-term use
During by slurry impurity frictional influence, easily cause polyester twine initial line plucking, hook fiber and block mesh, drop drainage area
Low, energy resource consumption increase is long-term use of easily to produce bulge, corrugation, peels off difficulty and increases.Service efficiency is reduced to new mesh bag mistake
Filter the half of efficiency；In order to keep the high-air-permeability papermaking producer of mesh often need to carry out water under high pressure to filter disc using a period of time
Cleaning.Because hydraulic pressure it is excessive easily make polyester mesh bag deformation, rupture, the problems such as generation.Reduce the service efficiency of equipment；It is another
Kind uses stainless (steel) wire filter disc, because the fiber fines in plain boiled water are more so that fiber fines are difficult to stop on stainless steel filter screen
Stay, fiber fines are directly passed through from stainless steel filter screen by hole so that production efficiency is low, in order to prevent fiber fines
From stainless steel filter screen by the way that directly through, it is necessary to add substantial amounts of bed course slurry in plain boiled water, i.e. addition is substantial amounts of in hole
Long fibre, long fibre is set to form three-dimensionally stacked formation filter cake on stainless steel filter screen so as to reduce and improved by hole
Drainage matter.Mode is mixed with beating because domestic papermaking enterprise uses more, and chopped fiber ratio has reached 70% of wet end furnish or so.
Cause the bed course that more disk fibre recovery machines use to starch because the very few hardly possible of long fibre has formed filter cake, greatly reduce fiber recovery,
With the treatment effeciency of plain boiled water；What paper industry disk fibre recovery machine more than 90% in China's occurred in use at present asks
Topic：
A：The super small B of clear filtrate yield：Filtering water is poor and unstable C：The concentration of slurry is difficult to control D：Recovery
The few E of slurry：Power consumption consumption is big.
The content of the invention
In order to solve the above problems, present invention offer is a kind of simple in construction, and substituting paper pulp fiber using metallic fiber forms
Filter cake, the fiber fines in mthod of white water from paper making are carried out it is effective intercept recovery, and improve filtering water and water, conventional filter disk
The course of work：Turbid filtrate → clear filtrate → super clear filtrate；Metallic fiber filter disc filter process：Clear filtrate → super clear filtrate.By original
Three filter processes come are changed into present two filter processes so as to improve the production efficiency of polydisc.
Mthod of white water from paper making recovery filter disc of the utility model with metallic fiber, including filter disc support and it is arranged on filter disc support
Screen pack, the screen pack includes spacer screen and veil, is provided with several filter bores on spacer screen and veil, the spacer screen and
It is overlapping and be fixedly linked above and below veil, if being provided with dried layer metal fiber filter layer on the veil, each metallic fiber filter
Layer is arranged by three-dimensionally stacked mode to be formed by metallic fiber and multiple welded by hole, the metallic fiber with sinter
The mode connect is fixedly linked.
Preferably, metal fiber filter layer is arranged to three layers, respectively ultrafine metal fibers filter layer, in thin metallic fiber
Filter layer, thick metal fiber filter layer, the ultrafine metal fibers filter layer is 40-70 microns by bore dia；In it is thin
Metal fiber filter layer is 70-100 microns by bore dia, and thick metal fiber filter layer is 100- by bore dia
150 microns.
Preferably, three-layer metal fibrous filter layer putting in order on veil be followed successively by ultrafine metal fibers filter layer,
In thin metal fiber filter layer, thick metal fiber filter layer.
Preferably, three-layer metal fibrous filter layer putting in order on veil be followed successively by thick metal fiber filter layer,
In thin metal fiber filter layer, ultrafine metal fibers filter layer.
Thin metal fiber filter layer during preferably, three-layer metal fibrous filter layer putting in order on veil is followed successively by,
Ultrafine metal fibers filter layer, thick metal fiber filter layer.
Or preferably, a diameter of 20-50 microns of metallic fiber of ultrafine metal fibers filter layer, in thin metallic fiber mistake
The a diameter of 50-150 microns of metallic fiber of filtering layer, the metallic fiber of thick metal fiber filter layer is 150-300 microns.
The utility model structure is simple, using the multiple layer metal fibrous filter layer being arranged on veil with three-dimensionally stacked
What mode was formed is intercepted by hole to mthod of white water from paper making fiber, ensures filtering accuracy, and filter efficiency is high.Metallic fiber is to burn
The mode of knot welding is fixedly linked, and ensures its intensity.
Metal fiber filter layer is arranged to three layers, can effectively adjust filtering accuracy, ensures filter efficiency and filtering accuracy.
