DISPERSER OF OZONE-AIR MIX FOR DRINKING WATER TREATMENT

摘要

FIELD: machine building.SUBSTANCE: disperser for treatment of drinking water in bubbling contact tank comprises plate-shape case 1 of titanium with cover 2 perforated by laser to face water free surface in contact tank directed towards horizon. Union 4 to receive ozone-air mix into disperser is coupled with disperser base. Detachable perorated fluoroplastic 5-6 mm deep strap 5 is arranged over said cover 2 with clearance of 2-3 mm to allow detachable joint over the edges of cover 2 and alignment of bores in cover perforations if strap 5 and cover 2. Bores 6 in strap 5 are shaped to truncated cone diverging to cover side. Diameter of bores 6 of converged part of truncated cone is selected to make 1.5-2 times larger than maximum diameter of mix bubbles. Diameter of conical bore 6 is taken 25-40% larger than that of outlet section. Thicker parts of the support of said strap 5 have several drain channels 14 to communicate clearance between strap 5 and cover 2 with water in contact tank.EFFECT: decelerated mineral and biological fouling of cover openings, optimised recycling.2 dwg
