Method and system for locating and containing submerged fires in aerated and closed chambers for composting and bio-drying of waste and storage of solid flammable materials

摘要

The method that forms the object of the present invention is applied to closed areas where heaps or large layers of solid and potentially combustible material are placed, subjected to forced aeration due to process needs such as drying, bio-drying and the composting of the waste, or more simply to storage systems. A system for the bio-drying of waste comprises a substantially closed chamber C containing a support surface B and having apertures distributed uniformly for the passage of air, means for the depositing of the material on the support surface D , means for the aspiration of air V and for its conveying through the apertures of the support surface so as to traverse the layered materials 1,3,4 on the aforesaid support surface, and means of treatment of the aspirated air, such as for example bio-filters F . The method uses a system of monitoring of the carbon monoxide CO positioned on the air outgoing from the layer of materials 1,3,4 which acts on a system A of production and distribution of foam through the ejectors J , and a procedure for the search of the sector wherein the fire is found and for its extinguishing.
