Abstract:
1. A method for producing fine salt dust in the breathing air by a salt dust generator comprising: providing granular salt particle in a bottom of the salt dust generator, providing an air flow through a net disposed in an opening in the bottom of the salt dust generator, a direction of the air flow going-upwards from the bottom of the salt dust generator through a flow space region and into a tube section, the air flow causing changing a cross-sectional area of a flow space in the salt dust generator in the flow space region in the direction of the air flow, to decrease a speed of the air flow until a carrying capability of the air flow is not sufficient to lift heavier salt particles in the flow space and wherein the heavier salt particles fall back towards the bottom of the salt dust generator, regulating a power of the air flow so that when the salt particles fly in the air they rise to the flow space and that the salt particles in periphery area of the bottom of the salt dust generator around the opening are moved into the air flow, providing a plate in an upper region of the flow space and regulating the air flow to cause heavier particles in the air flow to collide with the plate, while lighter particles in the air flow escape the flow space through holes in a periphery of the plate, the upper region of the flow space being narrower than a middle region, decreasing a speed of the air flow in the tube so that the lighter particles entering the tube through the holes in the periphery of the plate so that salt particles that have a size greater than approximately 5 micrometers fall to a bottom of the tube, the tube being substantially horizontally oriented relative to the flow space region of the salt dust generator.
