Abstract
Decontamination is disclosed of an enclosed space, which can be at least one cubic meter, by liquid particles of controlled dimensions containing a contaminant neutralizing agent and able to reach all parts of the space and remain suspended therein for hours. The particles are generated by passing a carrier gas and a liquid contaminant neutralizing agent having controlled viscosity and surface tension through a Venturi generator. Chemical and microbiological contaminants are decontaminated according to the invention.
Claims18
A process for decontaminating an enclosed space containing a contaminant and surfaces surrounding the space, comprising the steps of
- providing a liquid contaminant neutralizing agent having a predetermined surface tension and viscosity,
- providing a source of carrier gas under a first pressure,
- providing a source of carrier gas under a second pressure greater than the first pressure,
- injecting said neutralizing agent into a stream of carrier gas under the first pressure, thereby generating a loaded stream of contaminant neutralizing agent and carrier gas,
- injecting a stream of carrier gas under the second pressure and the loaded stream into a venturi generator nozzle, thereby mixing the streams and generating a stream comprising carrier gas and particles of contaminant neutralizing agent having a predetermined particle size distribution,
- injecting the stream comprising carrier gas and particles of contaminant neutralizing agent into the enclosed space,
- causing particles of contaminant neutralizing agent to dwell in the enclosed space for a predetermined time, thereby decontaminating the enclosed space,
- and removing particles of contaminant neutralizing agent from the treated enclosed space.
