Patent ID: 7182919

Claim:
A sulphurous acid generator comprising: a source of sulphur dioxide gas; a source of water consisting essentially of water; a source of air/oxygen; a first conduit in fluid communication with the source of sulphur dioxide gas; a second conduit in fluid communication with the source of water, the second conduit comprising a first segment and a second segment; an air injector in fluid communication with the source of air/oxygen, the air injector being positioned along the length of the second conduit and at a distance from the discharge end of the second conduit, the distance being equal to the length of the second segment, wherein the air injector disperses the air/oxygen into the water being conveyed by the first segment of the second conduit to produce an air/oxygen enhanced water that is further conveyed by the second segment of the second conduit; and means for blending the sulphur dioxide gas being conveyed by the first conduit with the air/oxygen enhanced water being conveyed by the second segment of the second conduit in a codirectional flow to form a sulphurous acid.
