Abstract

The objective of the invention is to make more efficient, by a prolonged duration, the existing processes for absorbing moisture from air with calcium chloride. The aim is to protect for as long as possible and not to desiccate. To attain it, the contact of air with calcium chloride must be slowed down; by employing the presentation in the form of flat flakes which are tamped or which are compressed, which has the effect of reducing the entry of air within the mass; by reducing the contact of air with the outer surface of the mass present in a sheath, by employing one or more sheaths reducing the air flow, a receptacle provided with adjustable aeration openings.

Description

X v E S
La présente invention concerne un dispositif permettant de rendre plus efficace par une durée prolongée les procédés existants d'absorption -de l'humidité de l'air par le chlorure de calcium.X v ES
The present invention relates to a device making it possible to make the existing methods of absorption of air humidity by calcium chloride more effective over an extended period of time.

Il existe divers procédés et dispositifs utilisant le chlorure de calcium, soit en le plaçant dans une simple gaine ajourée, soit sans gaine sur ou dans un support aéré, et pour chaque procédé l'ensemble est situé sur ou dans un récipient destiné à recueillir le liquide obtenu par absorption de l'humidité de l'air ambiant. There are various processes and devices using calcium chloride, either by placing it in a simple perforated sheath, or without sheath on or in an aerated support, and for each process the assembly is located on or in a container intended to collect the liquid obtained by absorption of humidity from the ambient air.

Le chlorure de calcium se présente sous forme de paillettes et l'ensemble de ces paillettes laisse pénétrer très facilement l'air ce qui provoque un dessechament rapide de celui-ci et une usure trop rapide du chlorure de calcium. Calcium chloride is in the form of flakes and all of these flakes allow air to penetrate very easily, which causes rapid drying thereof and excessively rapid wear of calcium chloride.

Le but en fait n'est pas de dessecher mais de protéger. The goal in fact is not to dry out but to protect.

Les procédés et dispositifs actuels destinés à absorber l'humidité de l'air, l'absorbent trop rapidement parce que le contact air et paillettes de chlorure de -calcium est trop intime. Current processes and devices intended to absorb moisture from the air, absorb it too quickly because the contact air and flakes of -calcium chloride is too intimate.

Ce que l'on demande à ces dispositifs c'est de protéger et de conserver le plus longtemps possible. What we ask of these devices is to protect and conserve as long as possible.

Les dispositifs actuels d'absorption de l'humidité placés dans une résidence secondaire fermée durant plusieurs mois, ou utilisés dans une pièce occupée s'usent beaucoup-trop vite et ne remplissent pas complétement leur ooe de protection. Current humidity absorption devices placed in a second home closed for several months, or used in an occupied room wear out far too quickly and do not completely fulfill their protective ooe.

D'autre part quand la température et le taux d'humidité sont élevés, du chlorure de calcium est entrainé agec la solution formant ainsi une solution sursaturée, il suffit d'une légère baisse de la température pour provoquer une recristallisation, diminuant ainsi le rendement de l'absorption. On the other hand when the temperature and the humidity are high, calcium chloride is entrained with the solution thus forming a supersaturated solution, it is enough for a slight drop in the temperature to cause recrystallization, thus reducing the yield. of absorption.

Le dispositif de l'invention est caractérisé principalement par une modération du phénomène d'absorption et une meilleure efficacité. The device of the invention is mainly characterized by moderation of the absorption phenomenon and better efficiency.

la description ci-après donne des exemples non limitatifs de #réalisations
Par tassement spécial après introduction dans la gaine, on obtiens un ensemble très dur et très caractéristique, car les paillettes plates se superposent et forment une masse plus compacte.the description below gives non-limiting examples of # realizations
By special packing after introduction into the sheath, we obtain a very hard and very characteristic set, because the flat flakes are superimposed and form a more compact mass.

Au lieu d'utiliser une seule gaine, après tassement on place l'ensemble dans une autre gaine. Instead of using a single sheath, after compaction, the assembly is placed in another sheath.

On introduit avec le chlorure de calcium un produit adhésif, l'ensemble comprimé ou non, limitant encore la pénétration de l'air à l'intérieur. Seule la surface extérieure est en contact avec l'air ambiant, cette surface extérieure absorbante est continuellement renouvellée par l'absorption de l'eau contenue dans 1 air et sa coulée dans un récipient, de la solution.An adhesive product is introduced with the calcium chloride, the whole compressed or not, further limiting the penetration of air inside. Only the external surface is in contact with the ambient air, this absorbent external surface is continuously renewed by the absorption of the water contained in the air and its pouring into a container, of the solution.

Quand le chlorure decalcium est placé dans un récipient sans gaine sur ou dans un support aéré, ou avec gaine il suffit pour obtenir une durée prolongée de disposer d'un récipient fermé muni d'ouvertures d'aération, réglables suivant les résultats que l'on veut obtenir. When decalcium chloride is placed in a container without sheath on or in an aerated support, or with sheath it is enough to obtain a prolonged duration to have a closed container provided with ventilation openings, adjustable according to the results that the we want to get.
