1. A device for on-line light radiation in gas-containing liquid comprising:
- a gas-liquid mixer comprising;
a liquid inlet through which a liquid is introduced in;
a gas inlet through which a gas is sucked in and mixes with said liquid such that at least part of said gas is dissolved in said liquid to produce a gas-liquid mixture; and
a gas-liquid outlet through which said gas-liquid mixture flows out;
a gas-liquid separator comprising;
a conduit provided inside said gas-liquid separator with a lower end thereof connected to said gas-liquid outlet of said gas-liquid mixer and an upper end thereof extending to near a top of said gas-liquid separator, a top of said upper end being sealed and multiple pores being formed near said top of said upper end;
an outlet disposed near a bottom of said gas-liquid separator; and
a gas-release valve disposed near said top of said gas-liquid separator;
multiple lamps disposed coaxially inside protective sheaths transparent to light respectively, said protective sheaths being disposed inside said gas-liquid separator, placed around and generally parallel to said conduit, and fixed on said bottom of said gas-liquid separator; and
a washing assembly for removing accretions on said protective sheaths, said washing assembly comprising;
at least one holder having plural through holes and a center hole allowing said conduit of gas-liquid separator to pass through, each of said plural through holes having a scraper mechanism therein for scraping said accretions on each of said protective sheaths, through said scraper mechanism, each of said protective sheaths passing through; and
means for driving said at least one holder to move axially along said protective sheaths;
wherein said gas-liquid mixture together with an un-dissolved gas are drawn into said conduit of said gas-liquid separator from said gas-liquid outlet of said gas-liquid mixer and said gas-liquid mixture is sprayed against an inner wall of said gas-liquid separator through said multiple pores of said upper end of said conduit where said un-dissolved gas is separated from said gas-liquid mixture and remains near said top of said gas-liquid separator and creates a partial pressure of gas, which is adjustable by said gas-release valve of said gas-liquid separator while said gas-liquid mixture flows downwardly and is radiated by said multiple lamps and then flows out from said outlet of said gas-liquid separator.

Abstract
A device for on-line radiating gas-containing liquid with light that can mix ozone and water, and radiate the same on-line as well as remove accretions on protective sheaths (preferably quartz tubes) of the device to reduce energy loss. Ozone and water is mixed in a gas-liquid mixer of the device and the ozone-water mixture is guided by a conduct of a gas-liquid separator of the device and spayed out to be radiated by multiple UV lamps protected by the protective sheaths. The accretions on the protective sheaths are removed by scraper mechanisms of a washing assembly of the device.

13. A scraper mechanism comprising:
-
a generally hollow-cylinder-shaped housing forming an inner flange in a bottom thereof; a ring-shaped stopper fixed in said housing and flush with a top of said housing, said stopper and said inner flange of said housing defining a chamber; and at least one ring-shaped scraper, having a tapered inner edge, being disposed and movable in said chamber, and having an inner diameter smaller than those of said stopper and said inner flange. - View Dependent Claims (14, 15, 16)
