APPARATUS FOR PURIFICATION AND DISINFECTION OF WATER Russian patent published in 2022 - IPC C02F1/32 C02F1/36 C02F1/64 C02F1/78 C02F9/00 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to mechanical engineering and can be used for purification and disinfection of water. The apparatus comprises a body equipped with a cover with ledges on the lower surface thereof. Ultraviolet LEDs are installed on the inner surface of the cover. A sealed casing repeating the shape of the body is installed outside of the body. Ultrasonic emitters are installed on the inner surface of the casing. The settling tank is shaped as a hollow hemisphere with the centre facing downwards, and is equipped in the lower part with a drainage bolt located in the centre thereof. An inlet ozone fitting is tangentially installed in a horizontal plane in the upper part of the casing. A water inlet branch pipe is tangentially installed opposite the inlet ozone fitting. An outlet branch pipe is installed in the cover. A perforated tube with a deflector shaped as a logarithmic spiral installed thereon is installed vertically in the body. A dish with perforated edges is installed bottom-down on the deflector. The outer diameter of the dish is equal to the inner diameter of the body. The filtering element is shaped as a cylinder. An additional deflector shaped as a flat spiral, the width whereof is equal to the distance between the body and the casing, is installed in the cavity between the body and the casing. A collector shaped as a bottom-down dish with a centre hole is installed at the end of the perforated tube. The diameter of the hole is equal to the outer diameter of the perforated tube. The diameter of the collector is equal to the outer diameter of the body. The edges of the collector are in tight contact with the body. The lower end of the perforated tube is directed into the upper part of the cavity between the body and the casing through the central hole of the collector. The pitch of the spiral of the deflector is made smaller than the pitch of the spiral of the additional deflector, and the winding direction of the spirals of the deflector and the additional deflector is made opposite.

EFFECT: increased quality of purification and disinfection of water.
