Patent ID: 7767168

Claim:
A sanitization system for producing ozonated liquid, the system comprising: a pump for circulating liquid through the system; a fluid transfer valve for interfacing with a liquid source to be ozonated, allowing simultaneous flow into and out of the system; an ozone generator for forming ozone to be incorporated into the liquid; and a vortex-venturi for incorporating ozone into the liquid by providing accelerated entry of liquid into the vortex-venturi prior to mixing with the ozone, the vortex-venturi comprising: an annular interior chamber with a central longitudinal axis, the annular interior chamber of the vortex-venturi having a widened initial section, a narrowed waist section with ozone entry ports positioned therein, and a widened mixed fluid outlet section from which ozonated liquid is released; and a liquid inlet positioned tangential to the widened initial section of the annular interior chamber for tangential entry of the liquid into the annular interior chamber; the tangential entry of the liquid inducing a vortex flow of the liquid within the annular interior chamber, the vortex flow having a center of rotation, and a low pressure zone being located in the center of rotation; the ozone generator being in fluid communication with the vortex-venturi to provide ozone to the ozone entry ports positioned in the narrowed waist section of the annular interior chamber providing the ozone to the liquid in the low pressure zone.
