electrolytic cell with hydrogen gas development lingsapparatuur and method for the operation of an electrolytic cell and the win of hydrogen therefrom.

摘要

Disclosed is a bipolar electrolyzer having a horizontal hydrogen channel separate from the catholyte chamber. There are apertures between the horizontal hydrogen channel and the catholyte chamber to enable catholyte gas, i.e., hydrogen, with entrained cell liquor, to enter the channel. At one end of the channel is a gas disengaging chamber. The gas disengaging chamber includes a catholyte gas deflector interposed between the outlet of the horizontal channel and the interior of the disengaging chamber, hydrogen recovery means, and catholyte liquor recovery means. In the operation of an electrolytic cell as disclosed herein, catholyte gas, i.e., hydrogen gas with entrapped catholyte liquor, is removed from the catholyte chamber to the horizontal channel. The catholyte gas is then transported through the horizontal channel to the outlet of the horizontal channel and into the disengaging chamber. As the catholyte gas enters the disengaging chamber, its direction of flow is deflected while its linear velocity is reduced. The direction of flow of the gas is then reversed and the linear velocity reduced further, disengaging the catholyte liquor from the hydrogen. Finally, the hydrogen gas, substantially free of catholyte liquor, is recovered from the disengaging chamber.
