Abstract

Depollution and decontamination procedure involves collecting air with the aid of a pump and subjecting it to infrared laser irradiation to neutralize it. The pump is fitted with a computer-operated detector that initiates sampling and analysis of the air. The analyzed air is fed to a chamber containing a bactericidal laser radiation source. The radiation causes excited molecules to be come unstable and lead to a break in their covalent bonds, and absorbed energy is transferred to other molecules. Depollution and decontamination procedure involves collecting polluted or dangerously contaminated air with the aid of a pump (1) and subjecting it to infrared laser irradiation to neutralize it. The pump is fitted with a computer-operated detector (2) that initiates sampling and analysis of the air liable to be contaminated, and the analyzed air is fed to a chamber containing a bactericidal laser radiation source (4). The radiation causes excited molecules to be come unstable and lead to a break in their covalent bonds, and absorbed energy is transferred to other molecules.

Description

Projet de dépollution et de décontamination dans un espace clos. Appareil pour le réaliser 1 L'air des tunnels, des souterrains de métropolitains est pollué : gaz d'échappement, NO X et hydrocarbures, fumées noires et particules fines, brassage humain dans un air non renouvelé.  Project of depollution and decontamination in an enclosed space. Apparatus to achieve it 1 The air of tunnels, metropolitan subways is polluted: exhaust gas, NO X and hydrocarbons, black smoke and fine particles, human mixing in a non-renewed air.

Ces endroits ont été aussi dans le passé le lieu d'agressions terroristes par des gaz toxiques..  These places were also in the past the place of terrorist attacks by toxic gases.

La présente invention a pour objet un. procédé de dépollution mais aussi de défense en cas d'agression.  The present invention relates to a. process of depollution but also defense in case of aggression.

Un brevet précédent du même auteur prévoit une décontamination des gaz de combat dans l'atmosphère. Ce procédé ne peut être appliqué ici compte tenu du contact humain immédiat.  A previous patent of the same author provides for a decontamination of combat gases in the atmosphere. This method can not be applied here given the immediate human contact.

Le processus est néanmoins basé sur la photodissociation.  The process is nevertheless based on photodissociation.

Mode d'action.Mode of action.

Sous l'action d'un photon(rayonnement) (Laser),les molécules excitées présentent un excédent d'énergie et sont instables. Cet état entraîne une rupture d'une liaison covalente. Il n'est pas nécessaire que l'événement physique initial ait porté sur Un électron de cette liaison.  Under the action of a photon (radiation) (Laser), the excited molecules have a surplus of energy and are unstable. This state causes a covalent bond to break. It is not necessary for the initial physical event to have been for an electron on this link.

L'énergie absorbée peut migrer au sein de la molécule (migration intra moléculaire) la rupture se produisant au niveau de la liaison la plus faible.  The energy absorbed can migrate within the molecule (intra-molecular migration) the break occurring at the level of the weakest link.

Ou l'énergie absorbée est transférée à une autre molécule (migration INTER moléculaire)subissant la conséquence comme 25 si elle. avait été atteinte directement par le rayonnement.  Or the energy absorbed is transferred to another molecule (molecular INTER migration) suffering the consequence as 25 if it. had been directly affected by radiation.

Le rendement PHOTOCHIMIQUE des ruptures croit avec le degré de substitution des atomes de carbone.  The PHOTOCHEMICAL yield of breaks increases with the degree of substitution of carbon atoms.

Les Gaz de combat sont de longues molécules substituées contenant du chlore, du phosphore, du soufre, sur un 30 squelette de carbone.  Combustion gases are long substituted molecules containing chlorine, phosphorus, sulfur, on a carbon skeleton.

Hypothése de travail: 1 L'air pollué sera aspiré,ramassé,analysé,puis conduit par un tube en Teflon à une source Laser Infra Rouge dont la longueur d'onde et la puissance nous sont connues. Il sera relié à l'extérieur par un tuyau d'évacuation.  Working hypothesis: 1 The polluted air will be sucked up, collected, analyzed, then driven by a Teflon tube to a Laser Infra Red source whose wavelength and power are known to us. It will be connected to the outside by a drain pipe.

L'aspiration de l'air se faisant par une pompe au niveau d'une tète de prélèvement.  The aspiration of the air is done by a pump at the level of a sampling head.
