Patent

CA 2177286

The invention relates to a device for generating a fog, characterised in that it comprises: a) a first closed vessel (1) kept at temperature and filled with a mixture having such a vapour pressure curve that pressure can be generated by varying the temperature of the mixture; b) a second closed vessel (2, 2', 2") with a heat exchanger kept at a higher temperature; c) a pipe (7) with a valve (8) connecting the mixture from the first vessel to the second vessel (2, 2', 2"); d) an outlet (16, 16') in the wall of the second vessel (2, 2', 2") for distributing the fog generated under pressure in this latter vessel into the environment.

Dispositif générateur de brouillard, caractérisé en ce qu'il comporte (a) un premier récipient hermétique (1) maintenu à une certaine température et rempli d'un mélange dont la courbe de pression de vapeur est telle que l'on peut créer une pression en modifiant la température du mélange; (b) un second récipient hermétique (2, 2', 2") muni d'un échangeur thermique maintenu à une température plus élevée; (c) un tuyau (7) pourvu d'une vanne (8) mettant en communication le mélange du premier récipient avec le second récipient (2, 2', 2"); et (d) un passage de sortie (16, 16') monté dans la paroi du second récipient (2, 2', 2") et destiné à distribuer dans le milieu ambiant le brouillard créé sous pression dans ce dernier récipient.
