Abstract
The present invention relates to a separator made of a porous material intended to treat gaseous effluents which contain particles whose size is substantially less than one micrometer or of the order of one micrometer and comprising channels (2). According to the invention, channels (2) are delimited by a fibrous porous material such as batting.
Claims23
1) A separator made of a porous material, intended to treat gaseous effluents containing particles whose size is substantially less than one micrometer or of the order of one micrometer, and comprising channels (2), characterised in that channels (2) are delimited by a fibrous porous material such as batting.
4) A separator as claimed in any one of the previous claims, characterised in that the diameter of the fibers forming said material ranges between 2 μm and 100 μm.
5) A separator as claimed in any one of the previous claims, characterised in that the diameter of channels (2) running through said material ranges between 3 and 15 mm.
6) A separator as claimed in any one of the previous claims, characterised in that the length of channels (2) ranges between about 10 cm and about 200 cm.
7) A separator as claimed in any one of the previous claims, characterised in that the effluents flow in the turbulent state from one end of channels (2) to the other end.
8) A separator as claimed in any one of the previous claims, characterised in that the material of the fibers is a synthetic material.
10) A separator as claimed in any one of the previous claims, characterised in that the porous material comes in form of a sheet (11) comprising channels (2).
12) A separator as claimed in any one of the previous claims, characterised in that the porous material is made by piling up sheets (11).
15) A separator made of a porous material, intended to treat gaseous effluents containing particles whose size is substantially less than one micrometer or of the order of one micrometer, and comprising channels (2), characterised in that it comprises at least one module consisting of at least one sheet (11), made of a porous material, comprising channels (2) and arranged substantially parallel and at a distance from at least one other sheet, and in that it comprises at least one plate (16) made of an impermeable material having the same surface area as said sheet and provided with holes corresponding to channels (2) of sheets (11).
22) A separator as claimed in any one of the previous claims, characterised in that the porous material is charged with static electricity.
