ABSTRACT:
An exhaust filtration system that captures dust particles in water is provided. The filtration system removes a substantial part of the dust that is normally discharged into the environment with the air. The system includes: (a) device for filtering contaminated air to substantially remove debris therefrom and to thereby generate an initially filtered air with dust entrained therein; (b) an exhaust filtration system comprising a chamber having an air inlet to admit the initially filtered air into the chamber wherein the chamber contains water; (c) device for causing the initially filtered air to come into contact with the water to trap at least a portion of the dust from the initially filtered air to produce substantially dust-free air; and (d) device for discharging the dust-free air into the atmosphere.
