Abstract

In the process a filter separates the liquid from the trapped solid. The hydrocarbon is passed into a treatment cycle without preliminary stage of de-oiling by flocculation.

DESCRIPTIFDESCRIPTION

MACHINE DE TRAITEMENT DE L'EAU POLLUEE SERVANT A SEPARER L'HUILE DE L'EAU PAR LE PROCEDE DE FLOCULATION La présente invention concerne un dispositif pour traiter les rejets d'eau industriels chargée d'hydrocarbure, en particulier les condensats formés par les compresseurs d'air comprimé industriels qui se composent d'eau condensée chargée en huile.  The present invention relates to a device for treating hydrocarbon-laden industrial water discharges, in particular the condensates formed by the compressors. industrial compressed air which consists of condensed water loaded with oil.

Cette machine est basée sur le principe physico-chimique de la floculation pour séparer l'huile de l'eau.  This machine is based on the physico-chemical principle of flocculation to separate the oil from the water.

Ce dispositif d'une conception type colonne permet de limiter considérablement l'encombrement au sol de la machine.  This device of a column type design can significantly limit the footprint of the machine.

Un procédé interne de pré-homogénéisation permet de traiter directement les condensats arrivant des points de purge des circuits d'air comprimé.  An internal pre-homogenization process makes it possible to directly treat the condensates arriving from the purge points of the compressed air circuits.

Ce système élimine la nécessité de récupérer l'huile libre avant le traitement par floculation.  This system eliminates the need to recover free oil prior to flocculation treatment.

Le dessin annexé illustre l'invention: L'eau à traiter arrive sous pression aux arrivées 1, un récipient de petite dimension 2 recueille l'eau chargée en huile.  The accompanying drawing illustrates the invention: The water to be treated comes under pressure at the inlets 1, a small container 2 collects the water loaded with oil.

Un orifice situé en 3 permet de détendre l'eau qui arrive sous pression, à la pression atmosphérique.  An orifice located at 3 allows to relax the water that comes under pressure, at atmospheric pressure.

Une vanne pneumatique 5 laisse évacuer l'eau du récipient 2 dans le 20 récipient 6.  A pneumatic valve 5 allows the water to be discharged from the container 2 into the container 6.

Au moment ou l'eau à traiter arrive au niveau du détecteur de niveau 4, le mélangeur se met en marche en mode grande vitesse pour homogénéiser le bain, simultanément la vanne pneumatique 5 se ferme afin d'arrêter l'arrivée d'eau pendant le traitement.  At the moment when the water to be treated reaches the level detector 4, the mixer starts in high speed mode to homogenize the bath, simultaneously the pneumatic valve 5 closes in order to stop the water supply during the treatment.

2883862 -2- Après le cycle d'homogénéisation terminé, un deuxième cycle se met en route; au cours de ce cycle un floculent à base de bentonite 7 se mélange dans le bain 6, il est dosé par le distributeur 8.  After the homogenization cycle is completed, a second cycle is started; during this cycle a flocculent based on bentonite 7 mixes in the bath 6, it is dosed by the distributor 8.

Le mélange brassé par l'agitateur 9 se divise en deux parties, une partie liquide et une partie solide (flocons). Cette dernière est constituée de 30 bentonite agglomérée avec l'hydrocarbure à séparer.  The mixture stirred by the stirrer 9 is divided into two parts, a liquid part and a solid part (flakes). The latter consists of agglomerated bentonite with the hydrocarbon to be separated.

La troisième phase consiste à évacuer le mélange hétérogène dans un filtre qui sépare le liquide (eau dépurée) du solide piégé dans le filtre.  The third phase consists in evacuating the heterogeneous mixture in a filter which separates the liquid (purified water) from the solid trapped in the filter.

Lorsque le filtre type papier 10 est plein une opération de changement manuel de ce dernier est à effectuer.  When the paper type filter 10 is full, a manual change operation of the latter is to be performed.
