Abstract

When preparing aerosols for medical or technical purposes it is preferable that the aerosol contains a high concentration of small particles even at low gas flows. This demand has been satisfied by use of a primary flow (a) of compressed gas, which after impaction on a primary baffle, the plate or bar (8) forms a flow of radially expanding aerosol (b). Said aerosol flow hits a circular baffle in the form of the frustrum of a cone, the vortex separator, having a wall (9) at about 45‹ in relation to the flow (b). Said flow (b) is deflected towards the bottom of the nebuliser and by ejector effect creates a high flow (c-d), which will rotate around the wall (9). Large particles will disappear by impaction on the wall (9), by condensation with other large particles in the flow (b) and (c-d) and due to rapid changes of direction in the flow (c), while small particles in the primary flow (b) which to a large extend disappear has impaction on wall (9), follow and concentrate within the flow (c-d).
