Description
Installation de traitement d'eauxusées et sac utilisable dans cette installation.Wastewater treatment plant and bag usable in this plant.
La présente invention concerne le traitement des eaux usées, telles que des eaux d'origines industrielles ou communales.The present invention relates to the treatment of waste water, such as water of industrial or municipal origin.
Un tel traitement implique généralement une déshydratation des eaux résiduaires.Such treatment generally involves dehydration of the waste water.
Pour ce faire, de nombreux procédés sont connus qui utilisent des filtre-presses, des machines centrifuges, une filtration entre bandes presseuses, des sacs filtrants, etc..To do this, many methods are known which use filter presses, centrifugal machines, filtration between press bands, filter bags, etc.
L'utilisation de sacs filtrants est un procédé performant mais implique en général une installation compliquée, coûteuse et encombrante et un processus long et nécessitant un contrôle permanent (voir par exemple EP-B-0.067.795). The use of filter bags is an efficient process but generally involves a complicated, expensive and cumbersome installation and a long process requiring constant monitoring (see for example EP-B-0.067.795).
La présente invention vise à fournir une nouvelle installation de traitement d'eaux usées peu onéreuse grâce à l'utilisation d'organes du commerce, peu encombrante, ne nécessitant pas de surveillance du processus de filtrationséchage et mettant en oeuvre des sacs à jeter de prix de revient avantageux et faciles à manipuler.The present invention aims to provide a new inexpensive wastewater treatment installation through the use of commercial bodies, compact, requiring no monitoring of the filtering and drying process and using disposable bags cost effective and easy to handle.
A cet effet, l'invention a pour objet une installation de traitement d'eaux usées par filtration dans des sacs à jeter, caractérisée en ce qu'elle comprend des moyens de suspension, au-dessus d'une goulotte d'évacuation du filtrat, d'un sac filtrant par des anneaux et/ou des boucles du sac, ledit sac étant muni d'une embouchure fixe pouvant être reliée par un accouplement rapide à la sortie d'une pompe à membrane actionnée à l'air comprimé, l'entrée de ladite pompe étant reliée à la base d'un réservoir d'eau à traiter.To this end, the subject of the invention is an installation for treating wastewater by filtration in disposable bags, characterized in that it comprises suspension means, above a chute for discharging the filtrate. , of a filter bag by rings and / or loops of the bag, said bag being provided with a fixed mouthpiece which can be connected by a quick coupling to the outlet of a diaphragm pump actuated with compressed air, l 'inlet of said pump being connected to the base of a water tank to be treated.
L'utilisation d'une pompe à membrane actionnée par l'air comprimé assure un transfert optimal des suspensions des eaux usées et permet d'ajuster de façon précise, par réglage de la pression de l'air moteur, la pression à l'intérieur du sac et de la maintenir constante indépendamment de la vitesse de filtration.The use of a diaphragm pump actuated by compressed air ensures optimal transfer of the wastewater suspensions and makes it possible to precisely adjust, by adjusting the pressure of the engine air, the pressure inside of the bag and keep it constant regardless of the filtration speed.
De préférence, le sac filtrant est de forme parallélépipédique et comporte aux coins supérieurs deux anneaux ou une double boucle de manutention. Ces anneaux ou ces boucles utilisés pour la mise en suspension des sacs servent également à leur mise en place et à leur enlèvement, par exemple au moyen d'un engin de manutention à fourche.Preferably, the filter bag is of rectangular shape and comprises at the upper corners two rings or a double handling loop. These rings or loops used for suspending the bags are also used for their installation and their removal, for example by means of a forklift.
Selon une forme de réalisation de l'invention, le sac filtrant est à double paroi, une paroi interne filtrante en matériau synthétique non tissé et une paroi externe porteuse en tissu synthétique à large maille, les deux parois étant indépendantes ou liées l'une à l'autre, par exemple par couture.According to one embodiment of the invention, the filter bag is double-walled, an internal filtering wall made of non-woven synthetic material and an external supporting wall made of wide-mesh synthetic fabric, the two walls being independent or linked to one another. the other, for example by sewing.
L'invention prévoit également que l'embouchure est constituée par une tuyauterie souple débouchant au centre du sac et assujettie de manière étanche à la paroi interne par soudure, collage ou autre moyen équivalent.The invention also provides that the mouth is constituted by a flexible pipe opening into the center of the bag and tightly secured to the internal wall by welding, bonding or other equivalent means.
Pour l'accouplement rapide, l'invention prévoit qu'il comprend un manchon dont l'alésage intérieur cylindrique a un diamètre légèrement supérieur à celui du tube constituant l'embout, l'alésage intérieur comportant au moins une gorge annulaire dans laquelle est logé un joint gonflable relié à une source d'air comprimé. Le dégonflement du joint se fait par suppression de l'arrivée d'air comprimé, ce qui permet de sortir l'embout solidaire du sac et de jeter ensuite cet ensemble.For quick coupling, the invention provides that it comprises a sleeve, the cylindrical inner bore of which has a diameter slightly greater than that of the tube constituting the end piece, the internal bore comprising at least one annular groove in which is housed. an inflatable seal connected to a source of compressed air. The deflation of the joint is done by suppressing the arrival of compressed air, which makes it possible to take the end piece integral with the bag and then discard this assembly.
L'invention concerne également les sacs filtrants utilisables dans l'installation précédente.The invention also relates to the filter bags usable in the previous installation.
L'invention sera bien comprise à la lecture de la description suivante d'un exemple de réalisation de l'installation selon un exemple de réalisation de 1 invention, en référence au dessin annexé dans lequel:
-la figure 1 est une vue schématique d'une
installation,
-la figure 2 est une vue schématique d'un sac et
-la figure 3 est une vue schématique en coupe d'un
accouplement rapide.The invention will be clearly understood on reading the following description of an exemplary embodiment of the installation according to an exemplary embodiment of the invention, with reference to the appended drawing in which:
FIG. 1 is a schematic view of a
installation,
FIG. 2 is a schematic view of a bag and
FIG. 3 is a schematic sectional view of a
quick coupling.
L'installation selon l'invention utilise des sacs jetables ou perdus 1. Dans l'exemple représenté, les sacs 1 sont de forme parallélépipédique et présentent aux quatre coins supérieurs deux anneaux 2 ou une double boucle servant au transport et à la suspension des sacs dans l'installation. Les sacs 1 comportent une paroi ou enveloppe interne filtrante 3 en matériau synthétique non tissé et une paroi ou enveloppe externe porteuse 4 en tissu synthétique à large maille pour ne pas gêner la filtration. Les parois 3 et 4 peuvent être libres ou cousues ensemble.The installation according to the invention uses disposable or lost bags 1. In the example shown, the bags 1 are of parallelepiped shape and have at the upper four corners two rings 2 or a double loop used for transporting and hanging the bags in the installation. The bags 1 have an internal filtering wall or envelope 3 made of non-woven synthetic material and an external carrying wall or envelope 4 made of synthetic fabric with a large mesh so as not to hinder filtration. The walls 3 and 4 can be free or sewn together.
La face supérieure du sac 1 comporte une ouverture dans laquelle est enfoncée, de manière étanche par rapport à la paroi interne 3, une tubulure d'embouchure 5 qui peut être soudée ou collée à la paroi interne 3 et est jetée avec le sac 1 après usage.The upper face of the bag 1 has an opening in which is pressed, in a sealed manner with respect to the internal wall 3, a mouthpiece 5 which can be welded or glued to the internal wall 3 and is discarded with the bag 1 after use.
L'extrémité opposée de la tubulure 5 est raccordée, par un accouplement rapide 6 dont un exemple sera décrit en référence à la figure 3, à une tubulure de sortie 7 d'une pompe à membrane actionnée par air comprimé 8. L'entrée de la pompe 8 est raccordée, par une tubulure 9, à la base d'un réservoir d'eaux usées à traiter 10, en forme d'entonnoir dans l'exemple représenté. Le filtrat est évacué par une goulotte G et le rétentat avec le sac 1.The opposite end of the tubing 5 is connected, by a quick coupling 6, an example of which will be described with reference to FIG. 3, to an outlet tubing 7 of a diaphragm pump actuated by compressed air 8. The inlet of the pump 8 is connected, by a pipe 9, to the base of a waste water tank to be treated 10, in the form of a funnel in the example shown. The filtrate is discharged through a chute G and the retentate with the bag 1.
L'accouplement rapide 6 représenté à la figure 3 comprend un manchon 11 à alésage intérieur cylindrique 12 dans lequel est ménagée une gorge annulaire 13. Un joint gonflable 14, relié à une source d'air comprimé 15, est logé dans la gorge 13 et vient serrer l'extrémité de la tubulure d'embouchure 5 de plus petit diamètre insérée dedans. La coupure de la source 15 libère la tubulure d'embouchure 5. The quick coupling 6 shown in FIG. 3 comprises a sleeve 11 with a cylindrical internal bore 12 in which is formed an annular groove 13. An inflatable seal 14, connected to a source of compressed air 15, is housed in the groove 13 and just tighten the end of the mouth tube 5 of smaller diameter inserted therein.
