Abstract

The device has a pumping pit (1) in which an electric agitator (3) for homogenizing a product and a pump (2) for supplying a separator (6) are installed. A float (4) is installed on the pumping pit for automatic initiating of an electric installation and automatic shutdown, and a flow meter (5) is arranged in a manner to allow the pump to supply the separator, where the product to be separated passes inside the flow meter when the pump supplies the separator. An independent claim is also included for a method for implementing a device for supplying a phase separator.

Description

L'invention concerne l'alimentation d'un séparateur de phase. Actuellement, tous les systèmes d'alimentation des séparateurs de phase sont alimentés avec des pompes à débit constant ce qui obligent d'avoir un tuyau de retour à la fosse de pompage pour le trop plein. L'invention consiste à palier à cet inconvénient. The invention relates to the supply of a phase separator. Currently, all phase separator power systems are powered with constant flow pumps which require a return pipe to the pumping pit for overflow. The invention consists in overcoming this disadvantage.

Un mode de fonctionnement de l'invention est maintenant décrit à partir d'exemples et non limitatifs en référence aux dessins annexés dans lesquels : An operating mode of the invention is now described on the basis of nonlimiting examples with reference to the appended drawings in which:

- La figure 1 est un schéma de principe pour expliquer le fonctionnement. Ce schéma de principe n'est pas limitatif aux différentes applications possibles et réalisables. - Figure 1 is a block diagram to explain the operation. This schematic diagram is not limiting to the different possible and feasible applications.

Avec le schéma de principe nous expliquons le fonctionnement : Nous avons une fosse de pompage (1) dans laquelle nous avons installé un agitateur électrique (3) pour homogénéiser le produit à séparer, une pompe (2) pour alimenter le séparateur (6) et un flotteur (4) pour la mise en fonctionnement en automatique de l'installation et l'arrêt automatique. Lorsque la pompe (2) alimente le séparateur (6) le produit passe à l'intérieur du débit mètre (5). En passant un l'intérieur du débit mètre (5), nous obtenons la lecture du débit passant à l'intérieur du débit mètre (5). En fonction du produit à séparer, le débit admissible par le séparateur (6) est différent. Pour contrôler automatiquement le débit admissible par le séparateur (6), nous commandons la vitesse de la pompe (2) par un variateur de vitesse (7) en tenant compte du débit lu par le débit mètre. Lorsque le niveau de la fosse de pompage (1) baisse, le débit de la pompe (2) diminue, donc le débit lu par le débit mètre (5) est inférieur au débit réglé en fonction du débit admissible par le séparateur (6), de ce fait le débit mètre (5) envoie l'information au variateur de vitesse (7) qui accélère la vitesse de la pompe (2) pour ajuster le débit au débit admissible par le séparateur (6). L'installation électrique est protégée par une armoire de protection électrique (8) aux normes. With the schematic diagram we explain the operation: We have a pumping pit (1) in which we installed an electric stirrer (3) to homogenize the product to be separated, a pump (2) to feed the separator (6) and a float (4) for automatic operation of the installation and automatic shutdown. When the pump (2) feeds the separator (6) the product passes inside the flow meter (5). By passing an inside of the flow meter (5), we get the reading of the flow passing inside the flow meter (5). Depending on the product to be separated, the flow rate allowed by the separator (6) is different. To automatically control the flow rate through the separator (6), we control the speed of the pump (2) by a variable speed drive (7) taking into account the flow rate read by the flow meter. When the level of the pumping pit (1) decreases, the flow rate of the pump (2) decreases, therefore the flow rate read by the flow meter (5) is lower than the regulated flow rate as a function of the flow rate allowed by the separator (6) as a result, the flow meter (5) sends the information to the speed controller (7) which accelerates the speed of the pump (2) to adjust the flow rate at the flow rate allowed by the separator (6). The electrical installation is protected by a standard electrical protection cabinet (8).
