Filed: 1995-10-25
Granted: 1997-09-27
Abstract: FIELD: water treatment. SUBSTANCE: ejector, contact chamber, degasser, and filter are installed on water-supply pipeline of ozonation plant. Gas cavity of degasser is linked with drying unit whose outlet is connected through discharge cavity of ozone generator with admission chamber of ejector. Drying unit is made in the form of gas-washing vessel of Drechsel bottle type filled with hygroscopic liquid, e.g. sulfuric acid. Gas path of plant after degasser communicates with atmosphere through window. Upon feeding water into plant, pressure in admission chamber of ejector is reduced. As a result of pressure drop, atmosphere air consecutively enters drying unit, ozone generator discharge chamber, and admission chamber of ejector wherein ozone-saturated air is mixed with water. In degasser, air and ozone not reacted with water are separated from water and conveyed into repeated drying-ozonation-water mixing cycle. Gas path of plant is replenished with air through special air passage. Because of law pressure drop in drying unit, gas circulation is provided by water-air ejector, whereas pressure in plant gas path is maintained below atmosphere pressure which simplifies plant structure and completely excludes getting ozonized gas into atmosphere. EFFECT: simplified structure and improved reliability. 1 dwg
