Title: Impurity-contg. gas removal appts. - dynamic seals in rotary symmetrically arranged components are mounted in segments on bearing-mounted circular disc etc.
Inventor: BOERNER THOMAS DIPL CHEM DR IN
IPC: B01D53/06
Filed: 1990-07-03
Abstract: Assemblies using a large number of rotary symmetrically arranged components which remove gases bearing heavy load of impurities such as solvents, have many dynamic seals. Newly, the segments are arranged to form a bearing-mounted circular disc, and the recovery system has at least two desorbtion hoods forming a gas-tight seal with the disc. At least one of the segments is covered on both sides at the same time and can still be removed. The discs can be rotated about their symmetrical axis in turn; and the desorbtion hood can be raised and lowered once within each cycle. Alternatively the disc may be stationary whilst the desorption hoods are rotated on a bearing. A third version uses a sandwich arrangement incorporating segments made of absorpttion material. A fourth version makes use of a cylinder with a hollow arrangement of segmented absorbers. USE/ADVANTAGE - Reduces the number of dynamic seals subjected to mechanical loads which are required.
