Patent ID: 8475725

Claim:
A system for treatment of a liquid, comprising: two coaxial sleeves, an inner sleeve and an outer sleeve, wherein the inner sleeve is located inside the outer sleeve; a first space between the inner and outer sleeve is filled with an excimer gas, forming a lamp, which irradiates an excimer UV radiation when a voltage is applied to two electrodes; both sleeves made of rigid material transparent to the excimer UV radiation; both sleeves are placed inside a reactor housing, the housing is coaxial with the sleeves; the housing containing an inlet and outlet for the flowing liquid subjected to the treatment and a gas inlet and a gas outlet for a flowing gas mixture; the liquid being treated is flowing inside the inner sleeve and is subject to treatment by the excimer UV radiation; and a second space between the outer sleeve and the housing contains the flowing gas mixture, which is also a subject to treatment by the excimer UV radiation at the same time as the liquid treatment; the flowing gas mixture enters the second space between the outer sleeve and the reactor housing via the gas inlet and exits via the gas outlet; oxidizing agents in the flowing gas mixture are produced under UV radiation action; the flowing gas mixture with the oxidizing agents to be used for an oxidation of contaminants in the liquid; the flowing gas mixture with the oxidizing agents passes through the liquid in a mixing chamber located downstream said excimer UV radiation treatment; wherein a double function of the same excimer gas UV radiation is achieved simultaneously in the same system the liquid UV treatment and a generation of the oxidizing agents in the flowing gas.
