Self-Cleaning Gas Filtering Apparatus
US Patent:
5439494, Aug 8, 1995
Filed:
Jul 29, 1994
Appl. No.:
8/282873
Inventors:
Charles G. Tullis - Longview TX
Bobby A. Hammer - Longview TX
Bobby A. Hammer - Longview TX
International Classification:
B01D 4600
US Classification:
55283
Abstract:
An improvement to self-cleaning gas filters, gas filter-separators or gas filter-coalescer devices. The improvement reduces the waste of gas during a self-cleaning cycle by a series of mechanical refinements to the internal seals, by improving the manufacturing steps, and by considering gas waste if the internal elements are damaged, during the cleaning cycle, by controlling the reverse gas flow based on differential pressure across the elements that are being cleaned. Some of the improvements are field retrofitable to existing devices whereas other improvements can only be made to the present art during the manufacturing phase.
Self-Cleaning Gas Filtering Apparatus
US Patent:

Appl. No.:
8/501629

International Classification:
B01D 4600
US Classification:
55283
Abstract:
An improvement to self-cleaning gas filters, gas filter-separators or gas filter-coalescer devices is disclosed. The improvement reduces the waste of gas during a self-cleaning cycle, by utilizing a single cage window rather then the usual plurality of cage windows, by a series of mechanical refinements to the internal seals, by improving the manufacturing steps, and by considering gas waste if the internal elements are damaged, during the cleaning cycle, through control of the reverse cleaning gas flow based on differential pressure across the elements that are being cleaned. Some of the improvements are field retrofitable to existing devices whereas other improvements can only be made to the present art during the manufacturing phase.
