Abstract
An improved means for sealing the gaseous product header of an electrolytic cell is provided which comprises a water trap positioned below the gas header duct and in communication therewith, a means for draining said water trap positioned in the lower portion thereof, a liquid inlet, preferably associated with said draining means, a non-porous baffle member extending from said header into the water trap and means connecting said draining means with said cell.
Claims4
In an electrolytic cell comprising an outlet for gaseous products formed in said cell, said outlet communicating with a header for collection of the gaseous products from a series of similar cells, the improvement which comprises attaching to said header a trap comprising
- a. a housing having a gas inlet communicating with the gas outlet of said cell,
- b. a baffle positioned in and extending across said housing, said baffle being attached to the top of said gas inlet and forming a part thereof, said baffle extending downwardly into said housing and terminating above the bottom thereof,
- c. a liquid outlet in the lower portion of said housing, said liquid outlet being at a lower level than the lower end of said baffle,
- d. a liquid inlet in the lower portion of said housing,
- e. means for conveying liquid from said liquid outlet to the gas outlet of said cell, and
- f. means attached to said liquid outlet for controlling the flow of liquid from said housing,
- Said gas inlet and said baffle forming a path through said trap for the flow of gaseous products from said cell through said trap into said header, said trap allowing a gas flow and acting to remove spray entrapped in the gas stream during normal cell operation, said trap preventing gas flow when said trap contains liquid to a level above the lower end of said baffle.
