The invention claimed is: 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, wherein the channels are delimited by a fibrous porous material in form of at least one sheet comprising the channels extending therethrough, wherein the at least one sheet is supported by a plate made of an impermeable material having the same surface area as the at least one sheet and provided with holes corresponding to the channels of the at least one sheet. 2. A separator as claimed in claim 1, wherein the porosity of said material ranges between 90% and 99%. 3. A separator as claimed in claim 1, wherein the size of the pores forming said material ranges between about 0.1 mm and about 5 mm. 4. A separator as claimed in claim 1, wherein the diameter of the fibers forming said material ranges between 2 μm and 100 μm. 5. A separator as claimed in claim 1, wherein the diameter of channels running through said material ranges between 3 and 15 mm. 6. A separator as claimed in claim 1, wherein the length of channels ranges between about 10 cm and about 200 cm. 7. A separator as claimed in claim 1, wherein the effluents flow in the turbulent state from one end of channels to the other end. 8. A separator as claimed in claim 1, wherein the material of the fibers is a synthetic material. 9. A separator as claimed in claim 1, wherein the material of the fibers is a ceramic material. 10. A separator as claimed in claim 1, wherein the thickness of sheet ranges between 1 and 10 mm. 11. A separator according to claim 1, wherein the fibrous porous material is made by piling up a plurality of sheets. 12. A separator as claimed in claim 11, wherein the sheets are arranged at a distance from one another by bracing means. 13. A separator as claimed in claim 1, wherein the porous material is charged with static electricity. 14. A separator as claimed in claim 1, wherein the fibrous porous material comprises batting. 15. A separator according to claim 1, wherein the channels extend in a flow direction of the gaseous effluents. 16. 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, wherein the separator comprises at least one module having at least one sheet made of a fibrous porous material, comprising channels therethrough and arranged substantially parallel and at a distance from at least one other sheet, comprising channels therethrough and at least one made of an impermeable material having the same surface area as each sheet and provided with holes corresponding to channels of sheets. 17. A separator as claimed in claim 16, wherein the porosity of said material ranges between 90% and 99%, the size of the pores ranges between about 0.1 mm and about 5 mm, and the diameter of channels ranges between 3 and 15 mm. 18. A separator as claimed in claim 16, wherein the effluents flow in the turbulent state over at least one face of sheet. 19. A separator as claimed in claim 1, wherein the module comprises at least two subassemblies of at least two sheets arranged at a distance from one another. 20. A separator as claimed in claim 16, wherein the sheets are arranged at a distance from one another by bracing means. 21. A separator as claimed in claim 20, wherein the bracing means consist of a frame. 22. A separator as claimed in claim 21, wherein the frame is obtained from the plated.
