Abstract
This invention presents a sulphurous acid generator which employs a combination of novel mechanisms which maximize the efficiency and duration of contact between sulphur dioxide gas and water to form sulphurous acid in an open nonpressurized system. The present invention also incorporates a novel high temperature concrete for use in constructing portions of the present invention. The present invention also employs means for substantially eliminating any discharge plume.
Claims12
A sulphurous acid generator apparatus comprising:
- a first conduit for conducting sulphur dioxide gas;
- a second conduit for conducting water;
- a third conduit comprising:
- means for bringing the sulphur dioxide gas conducted through the first conduit and the water conducted through the second conduit into contained, codirectional flow whereby the sulphur dioxide gas and water are brought into contact with each other;
- a passageway through which the sulphur dioxide gas and the water may codirectionally flow in contact with each other and in which at least a portion of the sulphur dioxide gas may react with water to form sulphurous acid;
- and
- a mixing tank connected to the passageway into which the sulphur dioxide gas and water empty from the third conduit;
- primary means for discharging the sulphurous acid from the apparatus;
- the mixing tank having an exhaust vent through which undissolved gases may exit the mixing tank;
- a vent conduit in communication with the exhaust vent;
- a supplemental water conduit for conducting a supply of water;
- a fourth conduit comprising:
- means for bringing the sulphur dioxide gas conducted through the vent conduit and the water conducted in the supplemental water conduit into contained, codirectional flow whereby the sulphur dioxide gas and water are brought into contact with each other;
- secondary means for discharging sulphurous acid from the apparatus;
- and
- means for substantially eliminating any discharge plume.

- a fourth conduit comprising:
- means for bringing the sulphur dioxide gas conducted through the vent conduit and the water conducted in the supplemental water conduit into contained, codirectional flow whereby the sulphur dioxide gas and water are brought into contact with each other;
- secondary means for discharging sulphurous acid from the apparatus, and
- means for conditioning intake air.
A sulphurous acid generator apparatus, wherein the sulphurous acid generator combusts sulphur creating radiant heat of and about the apparatus, the apparatus generating a discharge of gases and/or vapors into the air causing a visible discharge plume, the improvement comprising:
- means for substantially eliminating any discharge plume.
