Abstract

A filter for a liquid circuit has an ultrasound generator connected to it to prevent the filter from becoming blocked. In cases where the liquid being filtered has a low level of pollution the ultrasound generator can be programmed to operate periodically, while for liquids which are more polluted the ultrasound generator can operate continuously.

Description

NOUVEAU DISPOSITIF DE FILTRATION A NETTOYAGE AUTOMATIQUE POUR
CIRCUIT DE LIQUIDE.NOVEL AUTOMATIC CLEANING FILTRATION DEVICE FOR
LIQUID CIRCUIT.

L'invention conceme un nouveau dispositif de filtration pour circuit de liquide,
comportant au moins un filtre dans le passage du liquide et équipé d'un
système de nettoyage automatique
On connaît déjà d'après l'art antérieur ( FR 2 649 332 - B1 ) un dispositif de
filtration muni d'au moins un filtre aménagé au dessus d'une cuve de
décantation . Une dérivation munie d'une vanne de commande est prévue
pour court-circuiter une partie de l'ensemble de filtration. Un manomètre
permet la mesure des différences de pression en amont et en aval , indiquant
ainsi le niveau de perte de charge due au colmatage du filtre . A partir d'une
valeur de consigne programmée, un module de commande déclenche 1 '
ouverture de la vanne de commande de dérivation, la mise en
fonctionnement et l'arrêt du générateur d'ultrasons, I'ouverture de la vanne
d'évacuation, puis fermeture simultanément ou successivement des vannes
de commande de dérivation et d'évacuation.The invention relates to a new filtration device for a liquid circuit,
comprising at least one filter in the liquid passage and equipped with a
automatic cleaning system
Already known from the prior art (FR 2 649 332 - B1) a device for
filtration fitted with at least one filter fitted above a
decantation. A bypass with a control valve is provided
to short-circuit part of the filtration assembly. A pressure gauge
allows measurement of pressure differences upstream and downstream, indicating
thus the level of pressure drop due to clogging of the filter. From a
programmed setpoint, a control module triggers 1 '
opening the bypass control valve, setting
operation and shutdown of the ultrasound generator, opening of the valve
evacuation, then simultaneously or successively closing the valves
bypass and evacuation control.

Le dispositif décrit dans l'art antérieur est uniquement avantageux dans le
cas de liquides peu sales
Le dispositif selon la présente invention est remarquable en ce que le
fonctionnement assure un nettoyage complet en présence de liquides très
sales Il consiste à faire fonctionner le générateur d' ultrasons en continu
pendant le passage du liquide dans le circuit, ce qui résulte de façon
avantageuse en un retard de l'encrassage du filtre et un nettoyage des
circuits en présence de liquides très sales
La centrale de commande peut être programmée pour un régime d'application d'ultrasons soit de façon séquentielle, dans le cas de liquides peu sales, soit en continu pour des liquides très sales, introduisant ainsi une grande souplesse d'utilisation.The device described in the prior art is only advantageous in the
lightly soiled liquids
The device according to the present invention is remarkable in that the
operation ensures complete cleaning in the presence of very liquids
dirty It consists in operating the ultrasonic generator continuously
during the passage of the liquid in the circuit, which results so
advantageous in delaying the clogging of the filter and cleaning the
circuits in the presence of very dirty liquids
The control unit can be programmed for an ultrasonic application regime either sequentially, in the case of slightly dirty liquids, or continuously for very dirty liquids, thus introducing great flexibility of use.

Selon une caractéristique avantageuse de l'invention, le générateur d'ultrasons est mis en route dès le démarrage de la circulation de liquides très sales, et maintenu en fonctionnement continu. Lorsque le manomètre différentiel indique que le filtre est colmaté, la circulation de liquide dans le circuit est arrêtée, tout en conservant le fonctionnement du générateur d'ultrasons. Dans ces conditions, les ultrasons décollent les matières accrochées au filtre Les saletés et débris décrochés du filtre sont entraînés par un contrecourant de liquide et évacués à l'égout après ouverture de la vanne montée à cet effet.According to an advantageous characteristic of the invention, the ultrasonic generator is started from the start of the circulation of very dirty liquids, and maintained in continuous operation. When the differential pressure gauge indicates that the filter is clogged, the circulation of liquid in the circuit is stopped, while maintaining the operation of the ultrasonic generator. Under these conditions, the ultrasound takes off the materials attached to the filter. The dirt and debris unhooked from the filter are entrained by a countercurrent of liquid and evacuated to the sewer after opening the valve mounted for this purpose.

Lorsque les opérations d 'évacuation des débris est terminé, le circuit est remis en fonctionnement normal , tout en maintenant I ' application d'ultrasons When the debris removal operations are completed, the circuit is returned to normal operation, while maintaining the application of ultrasound.

Claims (1)

REVENDICATIONS 1 - Dispositif de filtration à nettoyage automatique pour circuit de liquide caractérisé en ce que le générateur d'ultrasons fonctionne de façon continue, remarquable en ce que le circuit reste propre lorsque le liquide en circulation est très saie; ce dispositif résulte de façon avantageuse en un retard de l'encrassage du filtre et des arrêts de l'installation moins fréquents. CLAIMS 1 - Automatic cleaning filtration device for liquid circuit characterized in that the ultrasonic generator operates continuously, remarkable in that the circuit remains clean when the circulating liquid is very dirty; this device advantageously results in a delay in clogging of the filter and less frequent plant stoppages. 2. Dispositif selon la revendication 1 , caractérisé en ce que la même installation peut être utilisée en régime de fonctionnement discontinu du générateur d'ultrasons lorsque le liquide du circuit est peu sale, soit en régime de fonctionnement continu dans le cas de liquides de circuit très sales. Dans les deux cas, la centrale de commande peut être programmée pour l'un ou l'autre des régimes de fonctionnement du générateur d'ultrasons en fonction du degré et de la rapidité de salissure du liquide circulant dans le circuit.  2. Device according to claim 1, characterized in that the same installation can be used in discontinuous operating conditions of the ultrasonic generator when the circuit liquid is lightly soiled, or in continuous operating conditions in the case of circuit liquids very dirty. In both cases, the control unit can be programmed for one or other of the operating modes of the ultrasound generator depending on the degree and the speed of soiling of the liquid circulating in the circuit.
