摘要

A particle collection apparatus is disclosed. The apparatus includes a baghouse housing comprising an entrance port, a collection port, a baghouse configured between the entrance port and the collection port, and a vacuum port coupled to the baghouse. The apparatus also includes a collection mechanism coupled to the collection port; and, a compression mechanism coupled to the baghouse.

主权项

1. A particle collection apparatus, comprising:
(A) a baghouse housing comprising
(i) an entrance port,(ii) a collection port,(iii) a baghouse, and(iv) a vacuum port;wherein (a) the baghouse housing is configured to process a particle flow through the entrance port directed to the collection port; (b) the baghouse is positioned inside the baghouse housing between the entrance port and the collection port in such a way an outer surface of the baghouse is exposed to the particle flow; and c) wherein the vacuum port is coupled to an inner volume of the baghouse to maintain a pressure differential in the baghouse housing so that particles of the particle flow are deposited on the outer surface of the baghouse due to the pressure differential;
(B) a particle collection mechanism coupled to the collection port; and, (C) a compression mechanism, which is attached to the baghouse and is configured to compress and twist the baghouse.
