Cross electrode type electrostatic separator for separation of coal fly ash

摘要

The present invention relates to a cross electrode type electrostatic separator for separating coal fly ash. More particularly, the present invention relates to an electrostatic separation apparatus for separating coal fly ash from coal fly ash, which can separate unburnt carbon components in a coal fly ash by a dry separation process using belt-type mutually intersecting rotating electrodes. The electrostatic separation device 30 of the present invention is an electrostatic separation device for separating the fly ash charged in the friction charging device 20 and the unburned carbon charged in the (+) direction, (+) Rotary electrode 41, a rotation driving wheel 42 for rotating the belt-type (+) rotary electrode 41, a power supply for supplying power to the belt- And a device 43. The collecting electrode 40 and the belt-like (-) rotating electrode 40 for collecting fly ash while rotating in one direction by loading the coal fly as supplied by the (40) (Not shown) for rotating the belt-type (-) rotary electrode 51, a power supply for supplying power to the belt-type (-) rotary electrode 51 And a device 53. The coal flyash collecting electrode 40 is spaced apart from the upper face of the coal fly ash collecting electrode 40 by a predetermined distance, An unburned carbon collecting electrode 50 for collecting the unburned carbon from the coal fly ash loaded on the coal fly ash collecting electrode 40 while rotating in one direction intersecting with the rotating direction of the fly ash collecting electrode 40, A coal fly ash recovery means composed of a coal fly ash recovery brush 44 and a coal fly ash hopper 45 for recovering fly ash collected in the coal fly ash collection electrode 40, (Not shown) and an unburnt carbon recovery hopper (not shown) for recovering the unburned carbon recovery brush (not shown).
