Description

PATENTANSPRUCH: Verfahren zur Wiedergewinnung des Lösungsmittels aus Filterrückständen bei Maschinen zur Chemisch-Reinigung, dadurch gekennzeichnet, daß die Rückstände aus den Filtern entfernt, in eine Destillierblase verbracht werden und dann mittels Wasserdampf das Lösemittel ausgetrieben wird. PATENT CLAIM: Process for the recovery of the solvent from filter residues in machines for chemical cleaning, characterized that the residues are removed from the filters, placed in a still and then the solvent is driven off by means of steam.

Verfahren zur Wiedergewinnung des Lösungsmittels aus Filterrückständen bei der Chemisdi-Reinigung Bei der Chemisch-Reinigung von Textilien, z. B. mittels Chlorkohlenwasserstoffen wie Trichloräthylen, Perchloräthylen u. dgl., muß das Lösungsmittel nach der Beendigung der Reinigung filtriert werden, bevor es wieder verwendet wird. Aus wirtschaftlichen Gründen ist es notwendig, das Lösungsmittel aus den Filterrückständen wiederzugewinnen. Versucht man dies durch Einblasen von warmer Luft zu erreichen, so muß man feststellen, daß dies außerordentlich viel Zeit in Anspruch nimmt. Auch das Einblasen von Wasserdampf ist ungünstig, da dadurch die Filterrückstände verhärten und infolgedessen die Filtereinsätze verstopft werden.Process for the recovery of the solvent from filter residues with chemisdi cleaning When dry-cleaning textiles, e.g. B. by means of Chlorinated hydrocarbons such as trichlorethylene, perchlorethylene and the like, must be the solvent filtered after cleaning is complete before being used again. For economic reasons it is necessary to remove the solvent from the filter residue to regain. If you try to achieve this by blowing in warm air, so one must realize that this takes an extraordinarily long time. Even Blowing in steam is unfavorable as it will harden the filter residue and as a result the filter cartridges become clogged. Es wurde ein einfaches Verfahren gefunden, bei dem diese Nachteile nicht auftreten. Es besteht im wesentlichen darin, daß die Filterrückstände in eine Destillierblase verbracht werden und darin durch Behandeln mit Wasserdampf von Lösungsmitteln befreit werden. A simple process has been found in which these disadvantages do not occur. It consists essentially in the fact that the filter residues in a Alembic and in it by treating with steam of solvents to be freed. Auf diese Weise können die Lösungsmittel restlos wiedergewonnen werden. Die Filtereinsätze können dann jeweils schnell wieder in Betrieb genommen werden und erleiden keinen Schaden.In this way, the solvents can be completely recovered. The filter inserts can then be put back into operation quickly and suffer no harm.
