Description
The present invention relates to a kind of aerosol fillter that is approximately cylindrical filtering surface that has some coaxial settings.
During filtration, there is MEDIA FLOW to be filtered to cross a filter.According to remaining the kind of filter medium, filter not of the same race is arranged.If will from air or liquid, separate fuel-displaced, aerosol or coalescent, then use aerosol fillter (suspended filter) usually, for example the printed matter Dubbel of Springer publishing house publication in 1987 " machine-building handbook the 16th edition, describe this by the M48 page or leaf.
In the aerosol fillter of this near cylindrical filtering surface that has some coaxial settings, there is medium to be filtered outwards to flow through filtering surface from the lining.Because the increase of cylindrical radius, filtering surface increases, and its effect is the increase along with cylindrical radius, reduces the speed that MEDIA FLOW is crossed filtering surface.It is agglomerating that the gathering of oil droplet or aerosol particle has been strengthened in the decline of flowing through the speed of filtering surface.The final increase gradually owing to weight of oil droplet of Zeng Daing and aerosol particle gradually because of gravity departs from the flow direction of medium, thereby is separated.
Filtering surface is made of ceramic component, glass fibre or staple fibre suede usually.But these materials receive the deposit that is filtered medium easily, stop up thereby form.Therefore, this aerosol fillter just must be changed after using very short time, and substitutes with new aerosol fillter.When particularly filtering the material of poisonous or radiation, should avoid comprising the deposit of these materials.
Therefore, the purpose of this invention is to provide a kind of for purifying also particularly suitable of poisonous and/or radioactive material, reproducible aerosol fillter.
Purpose of the present invention realizes by a kind of aerosol fillter that is approximately cylindrical filtering surface with some coaxial settings; these filtering surfaces have a kind of woven wire respectively; wherein; the woven wire of each filtering surface is respectively as the silk screen layer that is made of wire; except comprising that one determines the layer; also comprise a supporting layer and at least one protective layer, at this, definite layer pore opening of the woven wire of each filtering surface increases along with the increase of filtering surface cylindrical radius.
Find surprisingly, compare, seldom have oil or aerosol to be bonded on the woven wire with traditional filtering material.At this, with ceramic phase for example than the microroughness advantageous particularly of much smaller woven wire.Owing to use the filtering surface of woven wire, so this aerosol fillter can clean to such an extent that stay any residue hardly as aerosol fillter.Under situation about stopping up, this filter for example can also be cleaned easily by return air, and then can come into operation again, has so just avoided additional deposit.
For to definite pore size of each filtering surface regulation, thereby and make aerosol fillter can be particularly suitable for the flow section of medium, woven wire preferably includes some tissue layer that are made of wire.At this, the mesh size of woven wire is by a layer of determining or determine that layer is limited, and this layer supported by the thick Distribution Layer of comparing with it, and Distribution Layer itself is supported by thicker by comparison supports fabrics layer.For fear of damage, determine that a layer side that deviates from Distribution Layer covered by a protective layer.
For the agglomeration that helps oil droplet or aerosol droplets or assemble agglomeratingly, more advantageously, the pore opening of the woven wire of each filtering surface increases along with the increase of filtering surface cylindrical radius.Reach a kind of especially effectively oil or aerocolloidal separation thus.
Advantage of the present invention mainly is, one has some coaxial settings, has the aerosol fillter of the filtering surface of a woven wire respectively, can be cleaned easily and regeneration therefrom.Because oil droplet or aerosol particle can be bonded on this woven wire hardly, so this aerosol fillter has long especially service life.
Describe one embodiment of the invention in detail below in conjunction with an accompanying drawing, in the accompanying drawing:
Fig. 1 one has the drawing in side sectional elevation of the aerosol fillter of some filtering surfaces;
Fig. 2 is the profile of a woven wire of filtering surface.
In two accompanying drawings, identical parts are represented with identical mark.
Aerosol fillter shown in Figure 1 comprises columniform filtering surface 2,2 ＇ of being approximately of some coaxial settings, and wherein two only are shown among Fig. 1.Each filtering surface 2,2 ＇ has a woven wire 3.Filtering surface 2,2 ＇ of aerosol fillter 1 are separated each other by separator 4.Separator 4 guarantees to maintain a certain distance between per two isolation surfaces 2.
As shown in Figure 2, woven wire 3 was formed by different stacked adding.Be provided with supports fabrics layer 5, a Distribution Layer 6, one definite layer 8 and one protective layer 10, the stack each other of these layers at this.Each tissue layer 5,6,8,10 is made of a wire cloth 25,26,28,30, the thickness of each wire 25,26,28,30 has not only been determined each tissue layer 5 of being formed by adjacent wire 25,26,28,30,6,8,10 hole p, p ＇, p " and the thickness of p , and determined its size.As shown in Figure 2, the thickness of wire 25,26,28,30 is according to the function of each silk screen layer 5,6,8,10 and difference.Determine that layer 8 has the thinnest wire 28.Wire 28 weaves like this, makes that the pore opening p that determines layer 8 " is several microns." determine that filtering surface 2,2 ＇ that great particle is had a woven wire 3 keep here, great particle can pass this pore opening p.
Determine that layer 8 is supported by the Distribution Layer 6 with a thicker wire 26, Distribution Layer 6 is arranged on again on the supporting layer 5 itself.Supporting layer 5 is compared thicker wire 25 by one with the wire 26 of Distribution Layer 6 again and is constituted, and it all has than definite layer 8 bigger aperture p, p ＇ with Distribution Layer 6.Therefore, 5 pairs of filtrations of Distribution Layer 6 and supporting layer do not play conclusive effect.A side that deviates from Distribution Layer 6 of determining layer 8 is covered by protective layer 10, and protective layer 10 also has with determining layer 8 compares thicker wire 30, thereby has bigger hole p .
For the silk screen layer 5,6,8,10 of kind of woven wire 3 for example links together by melting welding, sintering or by other method of attachment, for a kind of anti-especially anti-aerosol fillter 1, woven wire 3 can be by a kind of anti-corrosion alloy, for example haas troy niresist (Hastelloy) or Ka Pengte (Carpenter) make, or by a kind of heat-resisting alloy, for example inconel constitutes.
By a kind of like this woven wire 3 is used on the aerosol fillter 1,1 pair of high temperature of aerosol fillter and low temperature and corrosion all have very high resistivity.In addition, this aerosol fillter has extra high mechanical strength and resistance to impact and high filtering precision.Such aerosol fillter 1 is easy to clean, and therefore can reuse often.
The pore opening of each filtering surface 2,2 ＇ woven wire 3 increases along with the increase of filtering surface 2,2 ＇ body diameters.In the embodiment shown in fig. 1, all radiuses are that the hole of silk screen layer of filtering surface 2 ＇ of R ' is that the hole of silk screen layer of filtering surface 2 of R is big than radius all.
Owing to the increase along with cylindrical radius R, R ＇ of the size of filtering surface 2,2 ＇ strengthens, the flow velocity of the medium that is filtered slows down when flowing through aerosol fillter 1 from inside to outside.Because reducing of this speed, the increase that oil droplet of forming according to agglomerating effect or gasoloid are dripped cylindrical radius R, R ＇ along with filtering surface 2,2 ＇ is increasing, therefore also becomes more and more heavier, like this, under the effect of gravity, they are preferably isolated in the perimeter of aerosol fillter 1.Because woven wire 3 is easy to accurately process especially,, thereby realized a kind of especially effectively filtration so filtering surface 2 for example with regard to the setting and the pore opening of its woven wire 3, can be well suited for being filtered the mobile section of medium.
Can clean aerosol fillter 1 by blowback, thereby make it regeneration.Can avoid precipitation by in filtering surface 2,2 ＇ of aerosol or filter 1, using woven wire 3.In addition, the life-span of this aerosol fillter 1 is very long.
