The invention relates to a cleaning device wherein polluted effluents are passed into a cage (2) where a partitioned ring (1) of vertical axis, containing a charge (M) of a solid material exhibiting a large heat exchange surface and, against the inner wall thereof, a catalyst bed (9), rotates. An autothermal working point is reached by including in the catalyst bed heating means (resistors for example) that are temporarily connected to the power supply system, after which the cleaning operations with rotation of the ring and effluent circulation are launched. Heat control is thereafter provided by controlled injection into the effluents of either a fuel or sprayed water for example by means of injectors (15, 16). The device can be applied in the field of incineration of VOC for example in industrial effluents.

Rotating catalytic cleaning device for polluted effluents

The invention relates to a packing block made by alternately stacking thin corrugated plates (P1, P3) with a first elongation direction (X1), thin corrugated plates with a second elongation direction (X2) different from the first, and sheets (2) made of a material adsorbing the contaminants, interposed between the various thin plates in this stack. Such a block is used to pack the units of a purification device and is disposed in a stream of effluents containing contaminants such that the effluents pass through the channels delimited by the corrugations of the corrugated plates and the interposed sheets.

Packing block with high adsorption capacity for gaseous effluent

A heat transfer device includes a ring having a vertical axis that can rotate inside a cage. The ring is inwardly provided with partitions. A permanent circulation of gaseous effluents is established on one hand between an effluent delivery pipe and a central zone via a first limited angular sector of the ring and on the other hand between the central zone and an effluent discharge pipe 6 via a second limited angular sector of the ring. The ring is charged with a mass of large heat exchange surface material and the device can be used for recovering positive or negative thermal energy. A thermal reactor of the catalytic bed type, for example, can be placed in the central zone for removing volatile organic compounds (VOC). The device may be used for catalytic or thermal oxidation of the organic compounds in gaseous effluents, for example.
