Title: Improvements in or relating to the production and use of hypochlorous acid gas
IPC: C01B11/04
Filed: 1945-10-03
Abstract: Gaseous hypochlorous acid is obtained from liquid or solid aerosols of hypochlorites or their solutions in an atmosphere containing a gaseous acid by progressively disintegrating the suspensions by repeated impacts on fixed or moving solid objects or by the conflicting actions of two or more air currents which are positively impelled to move in different directions, or by a combination of these means.  The weak gaseous acid may be atmospheric carbon dioxide, which may be supplemented by additional carbon dioxide, or acetic acid.  The air employed may be warmed and may contain chlorine or steam.  The aerosols may be projected against solid surfaces by the centrifugal action of fans or beaters which may move in close proximity in opposite directions; or the fans may throw the aerosols against the circumference of the fan chambers; or the aerosol may be carried by a swift air current on to a moving fan or fans, impellers and/or turbine blades, or through a conduit containing baffle plates or rotating discs.  A combination of the above methods may be used. By another method two fans are provided which face each other and drive opposing currents of air into the intervening space, from which space a conduit or conduits may lead the air back again to pass through the fans.  The atomiser described in Specification 577,365, [Group XXIX], may be used, the resulting sodium hypochlorite aerosol emitted from the jet within a conduit being carried by air streams to a series of fans and subjected to disintegration in the fancasings. The conduits between the fans may have adjustable ports for the supply of additional air.  If the residual aerosol is solid as when sodium hypochlorite is used, this may be separated, e.g. by an electrostatic precipitator. Specification 480,176 also is referred to.ALSO:Gaseous hypochlorous acid obtained by the disintegration of aerosols of hypochlorites or their solutions in an atmosphere containing a gaseous acid (see Group III) are used for the sterilization of air or solid or liquid objects.
