Gas purifying filter

A gas purifying filter, comprising:

• a housing;
• a gas inlet stub arranged on a side wall of the housing;
• a gas outlet stub arranged on a side wall of the housing;
• stationary filtering elements fabricated from fibrous chemisorbing material, said elements constituting rectangular plates formed of said fibrous chemisorbing material and rigidly secured inside said housing, positioned vertically and arranged in parallel with one another, each of said rectangular plates having opposed side edges and an upper section;
• a first plurality of partitions connecting said side edges of alternate adjacent pairs of said rectangular plates therebetween so as to provide an opening for the passage of gas between the plates essentially opposite the partition connecting said side edges of an adjacent pair of said rectangular plates;
• and
• liquid compartments overlying said rectangular plates, the liquid serving to regenerate said stationary filtering elements, each of said compartments defining a space communicating with said upper sections of said fibrous plates and such that the liquid directed into said compartments contacts only said upper sections of said rectangular fibrous plates.
