Title
(EN) GROUP OF AT LEAST TWO GAS-FLOW REACTORS SUPPLIED WITH CHEMICAL NEUTRALIZATION AND/OR SORPTION AGENT
(FR) GROUPE D'AU MOINS DEUX REACTEURS A FLUX DE GAZ ALIMENTES EN UN AGENT DE SORPTION ET/OU DE NEUTRALISATION CHIMIQUE
Abstract
(EN)
The present invention relates to a group of at least two gas-flow reactors (21, 22, 2'2, ..., 2n, 2'n) preferably with an ascending gas flow (3), which are supplied on the one hand, in parallel, with gas and on the other hand with a chemical neutralization and/or sorption agent of the pulverulent material type that is capable of adsorbing effluents present in said gas flow (3) by bringing said chemical neutralization and/or sorption agent in contact with said gas flow (3), said at least two reactors (21, 22, 2'2, ..., 2n, 2'n) having means (10) for collecting said chemical neutralization and/or sorption agent after it has been brought into contact with said gas flow (3), characterized in that at least one of said two reactors (2l, 22, 2'2, ..., 2n, 2'n) has means (11) for discharging said chemical neutralization and/or or sorption agent, after having been brought into contact with said gas flow (3), said means (11) being connected to said collecting means (10), and means (7, 16) for injecting the chemical neutralization and/or sorption agent into at least one other of said at least two reactors (2l, 22, 2'2, ..., 2n, 2'n).
(FR)
La présente invention porte sur un groupe d'au moins deux réacteurs (2l, 22, 2'2, ..., 2n, 2'n) à flux de gaz (3), de préférence ascendant, alimentés d'une part en parallèle en gaz et d'autre part en un agent de sorption et/ou de neutralisation chimique du type matière pulvérulente apte à adsorber des effluents présents dans ledit flux gazeux (3) par mise en contact dudit agent de sorption et/ou de neutralisation chimique avec ledit flux gazeux (3), lesdits au moins deux réacteurs (21, 22, 2'2, ..., 2n, 2'n) présentant des moyens de collecte (10) dudit agent de sorption et/ou de neutralisation chimique après mise en contact avec ledit flux gazeux (3), caractérisé en ce qu'au moins l'un desdits deux réacteurs (2l, 22, 2'2, ..., 2n, 2'n) présente des moyens d'évacuation (11) dudit agent de sorption et/ou de neutralisation chimique, après mise en contact avec ledit flux gazeux (3), et reliés auxdits moyens de collecte (10) ainsi que des moyens d'injection (7, 16) en agent de sorption et/ou de neutralisation chimique dans au moins un autre desdits au moins deux réacteurs (2l, 22, 2'2, ..., 2n, 2'n).
