Abstract

Cette invention concerne un procédé permettant de produire un gaz fumigène qui consiste en un mélange de phosphine et de gaz carbonique. Ce procédé consiste à ajouter, à la composition des réactifs de base, un liant, un acide ainsi qu'une substance qui dégage du gaz carbonique lors d'un processus chimique endothermique. On mélange un phosphure de métal, le liant et ladite substance dégageant du gaz carbonique, après quoi le mélange obtenu est mis en interaction avec un mélange d'acide et d'eau de manière à produire simultanément de la phosphine et du gaz carbonique. La chaleur émise est compensée par le déroulement du processus chimique endothermique lors de la production de gaz carbonique à partir de la substance introduite dans le mélange. Le dispositif de mise en oeuvre de ce procédé comprend un réacteur qui consiste en au moins une unité comprenant deux chambres communicantes. L'une de ces chambres renferme le mélange comprenant le phosphure de métal, ladite substance dégageant du gaz carbonique et le liant, tandis que l'autre chambre renferme le mélange d'acide et d'eau. Une ouverture de sortie pour le gaz fumigène est pratiquée dans la chambre renfermant le mélange d'acide et d'eau. Ce dispositif peut comprendre plusieurs unités et peut être transportable. Cette invention concerne également diverses variantes de procédés de fumigation, ainsi qu'un système permettant de réguler la concentration des gaz en fonction des types d'objets à traiter et des courants de convection dans ces derniers.
