摘要:
A multiple disc filter having a plurality of discs (10, 20) arranged in a stack with a face of each disc in contact with a face of the next adjacent disc in the stack; the contacting faces of the discs including surface formations defining small filtering passageways between the contacting faces of adjacent discs for filtering a fluid passing between the contacting faces; the surface formations including a rib array (11) of spaced rib sections (11a) integrally formed on a flat surface of one of the contacting faces; and a protrusion array of spaced discrete protrusions (21) spacing the rib array of the one contacting face from a flat surface of the other contacting face.
摘要:
A filter-cleaning device and method for cleaning a filter (10) a compressible fluid pulse generator (20) including a pressure tank (21), a tank inlet (23) for inletting pressurized air or other compressible fluid, and a valve member (24) normally in a closed position closing the tank outlet (28), but being openable in a quick-action manner to produce a high-pressure high-flow impulse of fluid applied via the tank outlet to the filter outlet to back-flush the filter.
摘要:
An air filter body (FB) includes a plurality of discs (10, 20) of electrically insulating material arranged in a stack and having ribbed contacting faces (11, 12, 21, 22) defining small filtering passageways between the contacting faces of adjacent discs. Each disc has an electrode (13, 23) insulated by the respective disc from the electrodes of the adjacent discs. Each electrode is electrically connected to an electrical terminal (14, 24) at an edge of the respective discs. Electrical conductors (31, 32) connect the electrical terminals of alternating discs to one side of a voltage source (30), and the electrical terminals of the remaining alternating discs to the other side of the voltage source.
