FILTERING ELEMENT FOR AIR-PURIFIERS AND THE LIKE.
at .12' `Rue. Carton, Clichy, Seine, France,
have invented Improvements-in. Filtering 'Elements for 4'Air-Puriiersand the like, of
which the Yfollowing is a specification.
This invention relates to air purlers and more particularlyto dust arresters and separators.
According-'to the present invention, the dust collector comprises a number of thin perforated sheets of cotton wadding or the ike fluffy material of very Vloose texture, suitably supported parallel to each other and close together, and in such manner that the holes in each of them are staggered with respect'to the holes of the succeeding sheet. With this arrangement, the air while passing through the perforations of the first sheet is sub-divided. into a plurality of separate jets, which impinge against. the imperforate parts of the next succeeding sheet and so on throughout the series. The effect of this is to-cushion the air jets and deflect them through the loose fibersof the wadding so as to entrap the dust particles by virtue of their own momentum,-which causes them to embed themselves in the dust entra'oping wadding, whereas the air itself is deflected so that it may pass on through the next series of holes.
In the preferred embodiment here disclosed, the perforated dust-entrapping baf- 1les comprise layers or sheets vlo or other suitable fibrous material each stuck or otherwise secured to a relatively rigid backing sheet, thus forming what may properly be termed. a baliie, the facing of fibrous material and the backing sheet being formed with perfor-ations that exactly coincide with each other. The complete or compound sheet or baille so obtained is then stuck, or otherwise secured'to a rigid support constituted by a frame properthat is to say a v frame the sides of which are not united by large mesh.
cross members, or if necessary the frame may be strengthened by a trellis work of portion of an air conduit itted with baie wa ddingj Specification of Letters'Pateiit.v Patented Jan. 26, 1l9i5. Appncatinaxed February e; iefa. I serial no. massa 'l y elements constructed according to this invention. Fig. 2 is an underside view of one of the baille elements.
Each element comprises a layer or sheet a of. wadding or other appropriate -fibrous or thread-y material stuck or -otherwisegconlveniently attached to a backing .sheet b which is preferably made of some material easily permeable 'by air. such as' tarlatan, linen or the like, but which may if necessary be (rigid and impermeable by 4air suchtas a sheet of cardboard, sheet iron, etc.
The two sheets a and b are perforated with identical holes al, b1, each of the holes al in the sheet or layer a coinciding exactly with a hole b1 in the backing .sheet b. To insure the perfect alinement of the holes vthe perfor-ations al and b1 are preferably produced simultaneously. v
The whole structure formed by the layer or sheet a andvbacking Z2 is stuck or otherwise attached to a rigid supporting frame c of wire which may be built up Of lengths of wire placed a convenient distance apart and if necessary be strengthened by other lengths of wire extending from side to side of the frame in order to form trellis work of very large mesh. Byv havingthe balles thus arranged adjacent to one another and spaced apart to forml unrestricted air passages therebetween, there is little change in the volume of air passed through the separator whether the wadding is clean or dirty. Each baille divides the current of air into a plurality of separate jets which impinge on the next baie of the series, and the dust thus forcibly projected against the baille is embedded by its own momentum in the wadding, and is there entrapped and held. Such dust as ma escape entrapment in the first baille o the series will be entrapped in subsequent baffles, so that the airon leaving the separator may be made substantially pure. l
It will be readily seen that in a dust colllecting-element constructed in this way the whole of its perforated area is free for the passage of air and the element is so rigid that it cannot get out of shape during the working of the apparatus.
The supporting frame c may readily and safely be shaken for cleaning purposes as the backing sheet b insures the fibrous layer or sheet a maintaining sufficient rigidity for its preservation.
What I claim is z* l. In a dust separator, a plurality of airbalies arranged adjacent to one another and spaced apart to form unrestricted airpassages therebetween, each of said baflies having perforations staggered with respect` to the perforations of adjacent battles to divide the current of air into a plurality of separate jets which .impinge upn the next baille of Athe series, each of said b es having a facing layer of fiuffed-up' Wadding providing a material of very loose texture cushioning the air jets directed thereagainst and defiecting it through the loose fibers thereoic to enti-ap and retain the dus particles carried by the air-jets.
2. baffle for dust separators i of thev character described2 consistin of'a sheet of wadding with perorations t erein, and a backing sheet of relatively rigid material for said Wadding having perforatons registering With those of the Wadding, said sheet of Wadding having its receiving face fiufed-up toprovide` a material of very loose texture,` cushioning an-air-jet directed thereagainst andv deecting it throughthe loose fibers thereof to entrap' andV dust particles carried by tiliegairfiet.v
