<p>The invention disclosed relates to the biological cleaning of pollutant gas. The device is comprised of a housing (1) consisting of a cyclone wherein the biofilter (20) is separated from the truncated portion (3) of the cyclone (2) by means of a wall (11) delimiting with said truncated portion an inlet chamber (12) for the fluid to be cleaned, and extending radially under the biofilter (20) from at least one inlet orifice (6) for the supply means (4, 5) to an annular outlet orifice (13) adjacent to the internal walls of the cyclone, so as to create a radial and centrifugal inlet flow in the chamber (12). Application to industrial gas effluents.</p> |
