摘要:
The invention discloses a filter (1) having an inlet mouth (4), through which a contaminated fluid (gas or smokes) can pass to the inside of the filter, at an appropriate temperature, and mixes there with fine water drops and then with liquid nitrogen flowing through showers (9, 10), all of which forming a hail-like mass which precipitates to a decanter (14) whre the separation of solidified contaminant particles will take place, said particles coming out to the outside through a discharge valve (15) while clean air will be expelled to the atmosphere through a chimmney (17). It is provided, as a second option, to incorporate a coil as a substituion to liquid nitrogen showers mentioned hereabove. Finally, it is to be noted that it is possible to avoid said water drops, depending on the type of contaminated fluid.
