Abstract
A wet cleaning apparatus including a sealed container adapted to hold a liquid, such as water. A separator compartment is disposed within the container and has an open bottom extending into the liquid within the container. The air to be cleaned enters the compartment within the container and a liquid is sprayed on such air causing the solid particles therein to be wet and heavy and drop into the water therebelow. The air in the separator compartment exits through a venturi scrubber having a nozzle for spraying this air with liquid as it goes through the venturi opening, further wetting down any additional solid particles in the air and causing them to drop into the water in the container as the air leaves the separator compartment. The air in the compartment then flows above the liquid, around a baffle, through a pre-filter, through a high efficiency particulate air filter and out through an exhaust fan as clean, breathable air. A nozzle disposed within the container and below the separator compartment is provided for causing the liquid having the most solids therein to circulate from below the separator compartment into the liquid in the rest of the container.
