Abstract
1407070 Electrostatic precipitators CARRIER CORP 8 Dec 1972 [14 Feb 1972] 56798/72 Heading B2J An electrostatic precipitator comprises an air flow chamber having end walls 21, 22; a pair of conductive grids 110, 111 extending across the chamber, grid 110 being connected to a positive potential derived from a first power pack (143) Fig. 10 (not shown) and grid 111 being connected to a negative potential supplied by a second power pack (147); a fibrous web 130 of nonconductive filter medium disposed between the grids 110, 111, a supply roll 131 of the medium being journalled in a supply compartment 25 and a take-up roll 137 of used medium being journalled in a collection compartment 27; and an ionising assembly removably mounted upstream of the grid 110, the assembly being in three sections separated by compressible strips 97. A sensor, e.g. a differential pressure switch, monitors the air flow through the filter and, in response to a predetermined reduction in this flow resulting from clogging of the filter medium in use, operates to energise a motor 153 whereby the used material is wound up on roll 137, means (171-177) Fig. 10 (not shown) being provided to ensure that the motor 153 remains energised until a length of web equal to the width of the air flow chamber has been advanced from the supply roll 131. A switch 200, actuated by an arm 195, energises a warning lamp when the roll 131 is exhausted. The ioniser assembly comprises earthed electrodes (70) Figs. 5 to 7 (not shown) which are of hollow rectangular construction and ionising electrodes (85) in the form of resiliently mounted wires which are also connected in the positive potential supplied by the first power pack 143.
