ABSTRACT:
A method for the removal of particulate matter as well as noxious gases and vapors from a gas stream. This is accomplished by means of charged droplets having a size between 60 and 250 microns and preferably between 80 and 120 microns. The droplets are generated by first ejecting a stable jet of liquid such as water. The liquid jet is broken up into charged droplets by applying an electric potential between the jet and the collecting walls of the scrubber. Since most gases are electronegative the droplets are preferably charged positively by the resultant electrostatic field. However, in case some of the particles are already charged it is preferred to generate charged droplets having a polarity which is the same as that of the particles. The method works well with particles having a diameter of approximately 0.01 micron or more and the droplets are preferably moved at an angle to the direction of movement of the gas stream to increase the relative velocity between the droplets and the particles. The droplets may include a chemical agent which chemically reacts with an undesirable fluid in the gas stream to remove it. The collector wall may be sprayed to flush particulate matter which may have been collected by the wall.
