Abstract
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.
