Electrolytic tank sealing structure and electrolytic tank

Abstract

The utility model provides an electrolytic bath sealing structure and an electrolytic bath, the electrolytic bath sealing structure comprises an end pressing plate, an end polar plate and a first sealing piece arranged between the end pressing plate and the end polar plate, and at least the end polar plate is provided with a liquid flow channel and a gas flow channel; in two opposite surfaces of the end pressing plate and the end polar plate, one surface is provided with an annular groove, and the other surface is provided with a first annular bulge matched with the interior of the annular groove; at least part of the first sealing piece is contained in the annular groove; the liquid flow channel and / or the gas flow channel are / is located in the annular groove or the first annular protrusion. According to the scheme provided by the invention, when the end pressing plate and the end polar plate are pressed tightly, the outer side edge and the inner side edge of the first sealing element are limited by the annular groove, are difficult to thin and are always limited in the annular groove to play a sealing role, so that gas and liquid leakage can be prevented, and the service life of the end pressing plate and the end polar plate is prolonged. And the electrolytic cell can be safely and stably used for alkaline water electrolysis hydrogen production.
