MOVING ELECTRODE OF MOVING ELECTRODE TYPE ELECTROSTATIC PRECIPITATOR

摘要

The moving electrode of a moving electrode type electrostatic precipitator which can increase the length of a collecting electrode plate while contributing to simplification in configuration of the precipitator and cost reduction. In the moving electrode (18) of an moving electrode type electrostatic precipitator which comprises a pair of drive wheels (20), a pair of driven rollers (22), a pair of endless chains (24) stretched between the drive wheels and the driven rollers, and collecting electrode plates (26) suspended by the pair of endless chains (24), and which is arranged to allow the collecting electrode plates (26) to move around a discharge pole, wherein a first auxiliary roller (32) is provided at the intermediate position of a rotating shaft (30) coupling the pair of drive wheels (20), and a second auxiliary roller (36) is provided at the intermediate position of a rotating shaft (34) coupling the pair of driven wheels (22), respectively. Permanent magnets are built in the outer circumference of the second auxiliary roller.
