Abstract:
A method and apparatus for collecting aerosol particles. The particles are subjected to an electrostatic charge prior to collection in an electrically resistive fiber bed. The method is applicable to particles in a broad size range, including the difficult-to-remove particles having diameters between 0. 01 and 2 microns.
Method For Removing Particulate Matter From A Gas Stream

Abstract:
Particulate matter is removed from a stream of pressurized gas by directing the stream of gas upwardly through a bed of porous material, the porous bed being held in an open ended container and at least partially submerged in liquid. The passage of the gas through the porous bed sets up a circulation in the liquid which cleans the particulate matter from the bed.
Thermophoretic Separation Of Aerosol Particles From A Sampled Gas Stream

International Classification:
G01N 122
US Classification:
7386312
Abstract:
A method for separating gaseous samples from a contained atmosphere that includes aerosol particles uses the step of repelling particles from a gas permeable surface or membrane by heating the surface to a temperature greater than that of the surrounding atmosphere. The resulting thermophoretic forces maintain the gas permeable surface clear of aerosol particles. The disclosed apparatus utilizes a downwardly facing heated plate of gas permeable material to combine thermophoretic repulsion and gravity forces to prevent particles of any size from contacting the separating plate surfaces.
