Abstract

An electrostatic liquid spraying apparatus having a sprayhead comprising a pair of atomising edges (12,13) extending side-by-side, liquid feed means (19) to each of the atomising edges and a plurality of field intensifying electrodes (26,27,28a,28b) extending lengthwise of the atomising edges (12,13). A pair of the electrodes (26,28a) are associated with one atomising edge (12) with one disposed on either side thereof and forwardly of the atomising edge (12). Similarly a pair of the electrodes (27,28b) are associated with the other atomising edge (13). Electric power supply means impose a potential difference between the atomising edges (12,13) and the electrodes (26,27,28a,28b). In order to achieve satisfactory spraying: a) the spacing between the atomising edges (12,13) is in the range, 20-300 mm. b) the spacing between each of the electrodes (26,27,28a,28b) and their associated atomising edges (12,13) is not less than 3 mm. and c) The measurable potential difference between the conductors through which the potential difference is imposed between the atomising edges (12,13) and the electrodes (26,27,28a,28b) is in the range 1-3 KV per mm. of the spacing of the electrodes (26,27,28a,28b) from the atomising edges (12,13). o [EP0404344A1]
