摘要： A system for filtering contaminants from a gas stream through atomized ultrafreezing including: a housing having an inlet mouth and an outlet mouth; a fluid temperature regulating element disposed within the inlet mouth; a venturi-type valve having a fluid speed regulator disposed downstream of the temperature regulating element; a down pipe disposed downstream of the venturi-type valve; at least one atomized water injector at the inlet of the down pipe which is capable of spraying the contaminated gas stream exiting the venturi-type valve; at least one liquid nitrogen shower element disposed in the down pipe downstream of the water injector which is capable of freezing the water, wherein water containing the contaminant is capable of solidifying into hail and precipitating; and a decanter connected to the outlet of the down pipe having a first separator for removing the hail from the gas stream, a discharge valve at the bottom of the decanter for discharging the hail from the decanter, and a second separator disposed downstream of the first separator and upstream of the outlet mouth for removing the hail from the gas stream. The contaminant may be separated from the hail by ultrasound. In a second embodiment, the liquid nitrogen shower element is replaced by a liquid nitrogen filled coil disposed around the down pipe and at least part of the decanter.
