ELECTROSTATIC DUST COLLECTING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an electrostatic dust collecting system for neutralizing dust which can not be collected in a dust collecting zone, and preventing wall surface adhesion contamination by charged particles without increasing the size of an electrostatic dust collecting device as a whole and deteriorating a dust collecting function. SOLUTION: A dust collecting unit is provided with an electrification part which applies high voltage and gives electric charge to dust, and a dust collecting part which captures electrified dust by a coulombic attraction force. The dust collecting block is constituted of a plurality of the dust collecting units and the electrostatic dust collecting system is constituted of a plurality of the dust collecting blocks and captures dust. The plurality of dust collecting blocks are classified into positive discharge blocks and negative discharge blocks per the dust collecting block so as to decrease the difference of processing capacity between the positive discharge blocks and the negative discharge blocks. The positive discharge blocks are connected to a high voltage generation board for positive discharge and the negative discharge blocks are connected to a high voltage generation board for negative discharge.
