DEVICE FOR LIQUID DISINFECTION WITH ULTRAVIOLET RADIATION Russian patent published in 2019 - IPC C02F1/32 

FIELD: water and air purification technology.

SUBSTANCE: invention relates to a device for liquid disinfection with ultraviolet radiation. Device has sealed cylindrical reactor housing-reactor (1), inside of which along its axis there is UV lamp (2) arranged in the form of straight tube, placed in sealed protective quartz cover (3). Cover (3) has open outlet through reactor housing-reactor (1) end for connection of lamp (2) power supply. Housing-reactor (1) has inlet (4) and outlet (5) branch pipes located at its ends. Inside housing-reactor (1) between inlet (4) and outlet (5) branch pipes one or several flow dividers (6) are installed in the form of crosswise axis of partition valve lamp, having several annular zones of equal width with common center on lamp (2) axis and evenly located along these zones of holes (7) for passage of liquid. At that, the zone closest to the common center is formed by the gap between protective casing (3) of the lamp and the edge of partition (6) and is completely open for passage of liquid, and total area of through holes (7) of each zone does not exceed this value for zone closest to it on side of common center, with possibility of creation and maintenance of divisors of distribution of liquid flow rate so that it was maximum near surface of protective lamp casing and gradually decreased at distance from it.

EFFECT: increased uniformity of irradiation of whole volume of processed liquid with ultraviolet irradiation and, as a result, increased degree of disinfection and efficiency of the device.
