Abstract

An electric dust precipitator comprising a chamber; a pair of groups of dust collecting electrodes disposed in the chamber; a plurality of discharging wires disposed between the dust-collecting electrode groups, a high d.c. voltage being applied to the wires and electrodes; and two horizontal scraping means each of which includes two sliding bars, adapted to slide along opposite surfaces of the electrodes and having brackets at the inside thereof, and drawing plates, wherein ends of the drawing plates in pairs are pivotally mounted on the brackets and the other ends of the drawing plates in pairs are commonly suspended by chains, respectively, whereby the dust precipitated on the electrodes can be easily and completely removed by winding up the chains and hence moving up the scraping means.

An electric dust precipitator comprising;

a pair of groups of dust-collecting electrodes disposed in parallel with each other in a chamber having a gas inlet and gas outlet;
a plurality of discharging wires disposed in parallel with and between said dust-collecting electrode groups, with a high direct current voltage being applied to said discharging wires and to said dust-collecting electrodes;
a horizontal scraping means being positioned around each of said groups and which includes a pair of sliding bars adapted to slide along opposite surfaces of said electrodes and having opposed brackets at the inside thereof, and a pair of drawing plates, one end of each of said drawing plates being pivotally connected to said brackets, and the other end of each of said drawing plates being commonly suspended by a chain;
and a winding means mounted above the top of said electrode groups for retracting said chain.
