DEVICE FOR PROCESSING LIQUIDS BY ULTRAVIOLET RADIATION Russian patent published in 2017 - IPC C02F1/32 

FIELD: physics.

SUBSTANCE: device for processing liquids by ultraviolet radiation has a hermetic cylindrical body-reactor 1, inside which one or several UV-lamps 2 are placed in hermetically sealed protective quartz covers 3 located parallel to its axis. The reactor body has an inlet and an outlet branch pipes, which are connected respectively to the inlet 8 and outlet 9 manifolds. The inlet manifold is located on the inner side surface of the reactor shell 1, extended along its entire length and has a number of evenly distributed inlet ports 10 along it. The output manifold is located on the axis of the reactor shell 1, stretched along its entire length and has a number of evenly distributed outlets. The inlet openings are oriented so that the flow of the treated liquid enters the reactor body 1 perpendicularly to its axis and tangentially to its lateral surface. Inside the reactor body, the flow moves along a converging spiral from the side surface to the outlets 10 of the output manifold 8, sequentially passing through the zones with different UV-radiation from the lamps 2. Then, the treated liquid stream through the discharge openings, the outlet manifold 9, and the outlet pipe, exits the device.

EFFECT: increasing the uniformity of irradiation with UV-radiation of the entire volume of the treated liquid and increasing the degree of disinfection or productivity of the device.
