Description

Polar plate pore canal supporting device Technical Field The application relates to the technical field of water electrolysis hydrogen production, in particular to a polar plate pore canal supporting device. Background The core component of water electrolysis hydrogen production is an electrolytic tank, and the electrolytic tank used at present is usually bipolar filter-pressing type. Wherein, a plurality of polar plates are sequentially stacked together, and the polar plates are sealed and insulated by gaskets. Each polar plate and the gasket are provided with a plurality of holes for circulating alkali liquor and gas. For a pressure type electrolytic tank, enough pretightening force is applied to the electrolytic tank through two ends to ensure that the electrolytic tank is effectively sealed, the temperature and the pressure of the standby working condition and the operating working condition of the equipment are greatly different, gaskets are easy to deform and invade the pore canal, the gaskets enter the pore canal to block the flow of liquid and gas, the electrolytic tank can generate suffocation, insufficient liquid supply and impurity accumulation, and the problems of increased energy consumption, reduced gas purity, abnormal temperature rise, polar plate corrosion and the like of the electrolytic tank are caused. Disclosure of utility model In order to reduce the probability of blocking the pore passage by the gasket, the application provides a polar plate pore passage supporting device. The application provides a polar plate pore canal supporting device which adopts the following technical scheme: the utility model provides a polar plate pore support device, includes the polar plate, a plurality of pore has evenly been seted up to polar plate circumference, polar plate one side paste and is equipped with the gasket, the through-hole is seted up to the gasket position that corresponds polar plate pore, through-hole intercommunication pore, the pore interpolation is equipped with the supporting ring, supporting ring one end is inserted and is located the pore in the other end is inserted and is located corresponding through-hole. Through adopting above-mentioned technical scheme, support sealed gasket through the support ring, reduce the probability that the gasket blockked up the pore to reduce because of the gasket gets into the flow of blocking liquid and gas that leads to in the pore, the electrolysis trough produces to hold down, supplies liquid inadequately and impurity piles up, causes the energy consumption of electrolysis trough to increase, gas purity decline, the unusual rising of temperature and polar plate corrodes the probability of scheduling problem. Optionally, the inner wall of the duct is fixedly provided with a receiving ring plate, and one end of the supporting ring inserted into the duct is abutted against the receiving ring plate.
