Sorption appts. for waste gas cleaning - has pivot flap for discharging spent sorbent

摘要

Sorption appts., for cleaning (esp. industrial) waste gases, has a sorbent-contg. vessel provided with a gas inlet and outlet, sorbent supply and discharge devices and a reaction space which has gas guide devices and which is bounded at the bottom by a support base, below which is located a collecting space in which the sorbent is discharged by a mechanically actuated displacement device. The (i) horizontally and vertically offset, stationary support elements are located below the uppermost support region of the support base and comprise a central element, with the greatest vertical spacing from the support region, and other elements which are spaced from one another and from the central element below the support region; and (ii) a displacement flap, which can pivot about a horizontal axis, is provided above the central support element and between the other support elements. ADVANTAGE - The design provides a relatively large open passage cross-section for the discharge openings so that a simple and reliable pivot flap can be used as the displacement device.
