Electrolytic bath capable of automatically separating hydrogen and electrolyzing seawater to produce chlorine

The invention belongs to the technical field of seawater electrolysis antifouling, and particularly relates to a hydrogen autonomous separation seawater electrolysis chlorine production electrolytic bath which mainly structurally comprises a bath body, a filter cotton partition plate arranged in the middle of the bath body, a hydrogen-containing seawater outlet formed in the upper portion of the bath body, a seawater inlet formed in the lower portion of the bath body and a chlorine-containing seawater outlet formed in the lower portion of the bath body. The cathode net is arranged above the filter cotton partition plate, the anode net is arranged below the filter cotton partition plate, the filter cotton partition plate, the cathode net and the anode net are parallel to one another, hydrogen-containing seawater and available chlorine-containing seawater are discharged through different pipelines during electrolysis so as to realize hydrogen separation, and the hydrogen separation device can be applied to spec
