Abstract
(EN)
The disclosure pertains to an electrochemical reactor (1), in particular but not exclusively for vatting sulphur dye or vat dye as well as to methods of using such a reactor and to uses of such a reactor. The electrochemical reactor comprises at least one liquid compartment (3) in which a multitude of freely suspended granules (14) is enclosed, wherein at least one of the side walls (5) of the compartment is an electrode and an opposite side wall is formed by a separator element (6), typically a membrane (6), wherein there is provided a bottom inlet (7, 9) and a top outlet (8, 10) of the compartment for a liquid catholyte (9) or a liquid anolyte (7), wherein the inlet region as well as the outlet region of the compartment (3) are provided with an upper grid (11') and a lower grid (11''), the width of the mesh and the positioning of which is chosen such as to allow the liquid catholyte or the liquid anolyte to pass through from bottom to top but to prevent the granules to pass through the grids to leave the compartment, and wherein the upstream flow of the liquid catholyte or of the liquid anolyte can be adjusted so that in operation the multitude of granules is dragged against the upper grid while the lower grid is substantially not in contact with the granules.

本发明公开涉及特别是但不仅仅用于还原硫化染料或瓮染料的电化学反应器(1)以及涉及使用这类反应器的方法和这类反应器的用途。所述电化学反应器包括至少一个其中封装了大量自由悬浮的粒状物(14)的液体室(3),其中所述室的至少一个侧壁(5)为电极,相对的侧壁由通常为膜的分隔元件(6)形成,其中在所述室上为阴极电解液(9)或阳极电解液(7)提供了底部入口(7,9)和顶部出口(8,10),其中所述室的入口区及出口区提供有上格栅(11′)和下格栅(11″),其网眼宽度和定位选择为使阴极电解液或阳极电解液可从底部流向顶部但阻止粒状物通过格栅而离开所述室,并且其中阴极电解液或阳极电解液的上升流可调节为使运行中所述大量粒状物被拖曳贴靠到所述上格栅上而所述下格栅基本不与粒状物接触。
