Viscous filter for gases essentially characterized by being constituted by a tubular chamber of any section provided at its ends of branchings for the entrance and exit of gas carrying at one end a lid lid or any other system suitable for the discharge of filtering material; the filtering material of which may be constituted by metal or wood chips, vegetable or animal fibers or other suitable material covered with a viscous substance capable of retaining, by adhesion, the dust particles that the gas may contain; this filtering material being arranged around a shank which has hooks distributed in a star, fixed at intervals along its entire length; supporting a tip of the stem in the center of a perforated plate attached to it and its portion proximate to the other end passing through a cone trunk attached to said rod conveniently; the bases of the cone-trunk being perforated or formed by radii; and this last end of the rod carrying a handle to be able to pull it by dragging the filtering charge when the discharge must be effected.
