Description

DESCRIPTION
L'invention concerne une installation de filtration d'un fluide gazeux contaminé, utilisant un matériau granulaire adsorbant et/ou absorbant, comportant un caisson incorporant des compartiments de filtration formés par des parois perforées en forme de losange, disposées spatialement avec une diagonale verticale, et maintenues à écartement l'une de l'autre par des entretoises périphériques obturatrices pour former des séries de compartiments plats, adjacents dont un, ou compartiment d'admission de fluide gazeux présente des ouvertures périphériques débouchant dans un collecteur commun d'admission de fluide gazeux à filtrer, dont un autre ou compartiment filtrant proprement dit présente une ouverture haute pour le remplissage de matériau granulaire adsorbant et/ou absorbant et ur.e ouverture basse pour le soutirage de matériau granulaire adsorbant et/ou absorbant, et dont un troisième ou compartiment d'évacuation de fluide filtré présente des ouvertures phériphériques débouchant dans un collecteur commun d'évacuation de fluide gazeux filtré. Une telle installation est décrite à la figure 5 du certificat d'addition FR 81 11989 de la Société 50FILTRA POELMAE; qui vise plus particul1orement une installation, où les collecteurs d'admission d'une part, d'évacuation d'autre part, s'étendent transversalement chacun sur deux cOtés adjacents du losange.
DESCRIPTION
The invention relates to an installation for filtering a contaminated gaseous fluid, using a granular adsorbent and / or absorbent material, comprising a box incorporating filtration compartments formed by perforated walls in the shape of a diamond, spatially arranged with a vertical diagonal, and kept apart from each other by obturating peripheral spacers to form a series of adjacent, flat compartments, one or gaseous fluid intake compartment having peripheral openings opening into a common fluid intake manifold gaseous to be filtered, of which another or proper filtering compartment has a high opening for filling of adsorbent and / or absorbent granular material and ur.e low opening for the withdrawal of adsorbent and / or absorbent granular material, and of which a third or filtered fluid discharge compartment has peripheral openings opening into a common collector for evacuating filtered gaseous fluid. Such an installation is described in FIG. 5 of the addition certificate FR 81 11989 of the company 50FILTRA POELMAE; which relates more particularly to an installation, in which the intake manifolds on the one hand, and the exhaust manifolds on the other hand, extend transversely each on two adjacent sides of the rhombus.

La présente invention a pour objet un perfectionnement simplificateur d'une telle disposition, et consiste en ce que les ouvertures d'admission des compartiments d'admission de fluide gazeux à filtrer d'une part, les ouvertures d'évacuation des compartiments d'évacuation du fluide gazeux filtré d'autre part, sont les unes et les autres limitées à un seul côté du losange. De la -sorte, on réduit l'encombrement de l'installation, sans pour autant, ainsi que l'expérience l'a montré, perturber la qualité de la filtration. The subject of the present invention is a simplifying improvement of such an arrangement, and consists in that the intake openings of the gaseous fluid intake compartments to be filtered on the one hand, the discharge openings of the discharge compartments filtered gaseous fluid on the other hand, are both limited to one side of the rhombus. From the -sort, the size of the installation is reduced, without, as experience has shown, disturbing the quality of the filtration.

Selon, une forme de réalisation, les côtés homologues des losanges correspondants aux ouvertures d'admission de fluide gazeux à filtrer sont adjacents un à un aux côtés homologues des losanges correspondants aux ouvertures d'évacuation du fluide à filtrer et, de préférence, les ouvertures d'admission et les ouvertures d'évacuation sont définies par les deux cotés inférieurs du losange. Cette dernière disposition est particulièrement intéressante, car elle permet de faire assumer aux collecteurs d'admission et d'évacuation un rôle porteur du caisson de filtration.  According to one embodiment, the homologous sides of the diamonds corresponding to the gaseous fluid inlet openings to be filtered are adjacent one by one to the homologous sides of the rhombuses corresponding to the discharge openings of the fluid to be filtered and, preferably, the openings intake and exhaust openings are defined by the two lower sides of the diamond. This latter arrangement is particularly advantageous, because it makes it possible for the intake and exhaust manifolds to assume a supporting role for the filtration box.

Les caractéristiques et avantages de l'invention ressortiront d'ailleurs de la description qui suit, à titre d'exemple, en référence aux dossiers annexés, dans lesquels - la figure 1 est une vue en élévation de côté d'une installation - la figure 2 est une vue en élévation de face de cette installation, selon les flèches A-B de la figure 1 avec arrachement partiel. The characteristics and advantages of the invention will moreover emerge from the description which follows, by way of example, with reference to the attached files, in which - FIG. 1 is a side elevation view of an installation - FIG. 2 is a front elevation view of this installation, according to the arrows AB in FIG. 1 with partial cutaway.

En se référant aux dessins, une installation de filtration comporte un caisson 1 incorporant des compartiments 2, 3, 4 formés de parois perforées (par exemple telle perforee de nombreux trous répartis de 1,2 mm de diamètre) 5 chacune en forme de losange 6 et disposées spatialement de raton qu'une diagonale A-B soit verticale. Les parois 5 sont maintenues à écartement l'une de l'autre par aes entretoises périphériques obturatrices 6A pour former une pluralité de compartiments plats 2,3,4, dont l'un, ou compartiment d'admiss-sn 2 présente des ouvertures périphériques 7 débouchant dans un collecteur commun d'admission de fluide gazeux 8, dont l'autre, ou compartiment de filtration proprement dit 3, présente une ouverture haute 9 communiquant avec un dispositif transversal 10 d'alimentation en matériau granulaire, et une ouverture bass li débouchant dans une goulotte évacuatrice 12 du matériau granulaire, et dont un troisième, ou compartiment d'évacuation 4 présente des ouvertures périphériques d'évacuation 13 débouchant dans un collecteur commun d'évacuation de fluide gazeux filtré 14. Referring to the drawings, a filtration installation comprises a box 1 incorporating compartments 2, 3, 4 formed by perforated walls (for example such as perforated numerous distributed holes of 1.2 mm in diameter) 5 each in the shape of a diamond 6 and spatially arranged in raccoon that a diagonal AB is vertical. The walls 5 are kept apart from each other by a shutter peripheral spacers 6A to form a plurality of flat compartments 2,3,4, one of which, or admiss-sn compartment 2 has peripheral openings 7 opening into a common gaseous fluid intake manifold 8, the other of which, or filtration compartment proper 3, has a top opening 9 communicating with a transverse device 10 for supplying granular material, and a low li opening opening into a discharge chute 12 of the granular material, and a third or discharge compartment 4 of which has peripheral discharge openings 13 opening into a common collector for discharging filtered gaseous fluid 14.

Toutes les ouvertures d'admission 7 des compartiments d'admission du fluide gazeux 2 sont limitées à un seul cté inférieur 15 du losange 6, tandis que toutes les ouvertures d'évacuation du fluide gazeux filtré 13 des compartiments d'évacuation 4 sont limités à l'autre côté inférieur 16 du losange 6. De la sorte, les collecteurs d'admission 8 et d'évacuation 14 ont une forme généraie prismatique rectangulaire de façon à former un élément de conduit tronqué transversalement, présentant, du côté d'une paroi verticale 18 une large bride L9 de raccordement à un conduit alimenteur, ou évacuateur, (non représenté), du côté horizontal une paroi du fond 20 et du côté du caisson 1, une pluralité de bandes parallèles à ouvertures réparties d'introduction vers les compartiments d'admission 2 (pour le collecteur 8), une pluralité identique de bandes parallèles à ouvertures réparties d'évacuation hors des compartiments d'évacuation 4 du fluide filtré vers le collecteur 14. Ces collecteurs de forme prismatique sont limités à leurs extrémités par des parois triangulaires 17 éventuellement équipées de trappes de visite 17 a. All the intake openings 7 of the gaseous fluid intake compartments 2 are limited to a single lower side 15 of the diamond 6, while all of the filtered gaseous fluid 13 discharge openings of the discharge compartments 4 are limited to the other lower side 16 of the rhombus 6. In this way, the intake 8 and outlet 14 manifolds have a generally rectangular prismatic shape so as to form a transversely truncated duct element, having, on the side of a wall vertical 18 a wide flange L9 for connection to a feeder or evacuator conduit (not shown), on the horizontal side a wall of the bottom 20 and on the side of the box 1, a plurality of parallel strips with openings distributed for introduction towards the compartments intake 2 (for manifold 8), an identical plurality of parallel strips with distributed discharge openings outside the discharge compartments 4 of the filtered fluid towards the manifold 14. These manifolds have the form prismatic are limited at their ends by triangular walls 17 possibly equipped with inspection hatches 17 a.

Ces collecteurs 8 et 14 forment une structure support pour le caisson 1 et, à cet effet, sont solidement fixés sur quatre piliers-support 21. These collectors 8 and 14 form a support structure for the box 1 and, for this purpose, are securely fixed on four support pillars 21.

Les ouvertures d'admission ou d'évacuation des compartiments d'alimentation ou d'évacuation du fluide gazeux peuvent etre circulaires, rectangulaires, ou constituées par une ouverture unique.  The inlet or outlet openings of the supply or outlet compartments of the gaseous fluid may be circular, rectangular, or constituted by a single opening.
