Abstract
The utility model discloses a superfine dust filter material. An acupuncturing composite layer is formed by taking superfine filters with the diameter of 0.1 micrometer as a face layer and common fibers as a bottom surface. The filter material is high in filtering precision, can effectively baffle the dust within the diameters of 0.5 micrometer, can not be collided and scratched when the material is used in installation, and can prevent a composite film from falling off, so that a prospective filtering effect can be achieved.
Description
Technical field
The utility model relates to a kind of filtering material, particularly relates to a kind of fine dust filtering material.
Background technology
Filtering material is widely used in the dedusting field of high temperature flue gases such as smeltery, steel plant, chemical plant, waste incineration and highly corrosive flue gas, is the indispensable material of waste gas wastewater treatment.Traditional micro mist filtering material is selected the PTFE overlay film for use, and its shortcoming is to the stretching of film and is laminated with requirement strictness especially that the pore size of oriented film and film directly influences filtering accuracy.The installation in later stage will notice relatively that also during film and filter material were laminated with, temperature height, pressure conference caused the filtrate air permeability seriously to reduce; It is insecure that temperature is low, the little meeting of pressure causes filtrate and film to be laminated with.
The utility model content
For solving the above-mentioned technical problem that prior art exists, the purpose of this utility model provides a kind of novel fine dust filtering material, select for use superfine fibre to do surface layer, general fibre is done bottom and is carried out acupuncture and be composited, but 0.5 micron of effectively catching is with interior dust, and needn't prevent also when installing and using that it from colliding with hang to draw, and worries to cause its film that is laminated with to come off, thereby does not reach the filter effect of its expection.
The technical scheme that the utility model solution prior art weak point is taked is: a kind of fine dust filtering material is characterized in that: filtering material is to do surface layer with superfine fibre, and general fibre is done the acupuncture composite bed of bottom.
The diameter of used superfine fibre is 0.1 micron.
The beneficial effects of the utility model are: this filtering material adopts superfine fibre to do surface layer, general fibre is done the acupuncture composite bed of bottom, the filtering accuracy height, but 0.5 micron of effectively catching is with interior dust, and needn't prevent also when installing and using that it from colliding with hang to draw, worry to cause its film that is laminated with to come off, thereby do not reach the filter effect of its expection.
Description of drawings
Fig. 1 is a cross-sectional view of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
A kind of fine dust filtering material of the utility model as shown in Figure 1, filtering material are to be that 0.1 micron superfine fibre 1 is done surface layer with diameter, and general fibre 2 is done bottom, and to carry out acupuncture compound, again superfine fibre combing 250g/m
2Fleece water acupuncture manipulation superfine fibre is separated (annotate: because of selecting the superfine fibre diameter for use is 0.1 micron, can't use the carding machine combing, Gu this several of fiber or tens are bundled together, reaches the fiber more than 1 micron, so that the machine teasing needle stings fleece).
Needing machine becomes felt on 1～2 micron the fiber to selecting for use with the acupuncture of superfine fibre fleece, and so far the superfine fibre face is a dust-collecting face, and can hold back 0.5 micron with interior dust.
Claims (2)
1. fine dust filtering material, it is characterized in that: filtering material is to do surface layer with superfine fibre, general fibre is done the acupuncture composite bed of bottom.
2. fine dust filtering material according to claim 1 is characterized in that: the diameter of superfine fibre is 0.1 micron.
