ABSTRACT:
A single high vacuum pump is connected to the downstream side of a pair of filtration chambers for collecting solid constituents from one or more pickup points upstream of the filtration chambers, entraining such solid constituents in a collection airstream, and separating the solid constituents from the airstream in the filtration chambers. Periodically, the filter screen of each filtration chamber is backflushed by a system of control valves which shut off the collection airstream thereto, opens the bottom gate of the filtration chamber to dump the accumulated constituents therefrom, and generates a reverse airflow path through the filter screen of the filtration chamber being cleaned. The reverse airflow path is then transferred to the other filtration chamber and through the filter screen thereof in the normal forward direction. Both the collection airstream and the reverse airflow are generated by the same high vacuum pump.
