Patent ID: 7833325

Claim:
A sorption column for waste-gas cleaning comprising a vat-shaped housing for receiving a solid stationary sorbent, said vat-shaped housing including a housing circumferential wall defining a longitudinal axis, a waste gas inlet provided with an inlet ball valve for selectively controlling entry of waste gas to be cleaned into the housing, and a waste gas outlet provided with an outlet ball valve for selectively controlling exit of cleaned waste gas out of the housing, wherein the housing circumferential wall has in the area of a housing bottom, an inlet depression for receiving the inlet ball valve at the waste gas inlet and, in the area of a housing cover, the housing circumferential wall has an outlet depression for receiving the outlet ball valve at the waste gas outlet, said sorption column including a first permeable cylindrical plate disposed within the vat-shaped housing above the inlet depression to form a lower chamber with the housing bottom, the lower chamber connected to the inlet ball valve to receive waste gas therethrough, and a second permeable cylindrical plate disposed within the vat-shaped housing below the outlet depression to form an upper chamber with the housing cover, the upper chamber connected to the outlet ball valve to output cleaned waste gas therethrough, and a solid stationary sorbent disposed within a center chamber defined between the first and the second permeable cylindrical plates and within the circumferential wall of the housing, wherein the solid stationary sorbent is prevented from entering either of the lower chamber or the upper chamber.
