1. A gas filter device (1) for filtering contaminants out of gases, wherein the gas filter device is a rain-tight freestanding cell, comprising:
a filtering apparatus (9) for filtering the gases, wherein the gases enter the filtering apparatus at a filter inlet surface (11), flow through the filtering apparatus, and exit the filtering apparatus at a filter outlet surface (13), and a distribution channel (15) for distributing the gases to be filtered along the filter inlet surface (11), wherein the filter inlet surface forms a permeable, lateral boundary surface of the distribution channel, and a collection channel (17) for collecting the filtered gases exiting at the filter outlet surface (13), wherein the filter outlet surface forms a permeable, lateral boundary surface of the collection channel, wherein the cross section of the collection channel (17) increases in the direction of flow of the gases, and the distribution channel (15) exhibits a constant cross section, and a heating device (25, 37) for heating the gases to be filtered in order to lower the relative moisture content of said gases before entering the filtering apparatus, wherein the heating device is located within the flow path of the gases in front of the filtering apparatus (9) with respect to the direction of flow and is extending across the entire cross section of the flow. |
