GAS CLEANER, MAGNETIC TREATMENT APPARATUS, AND GAS CLEANING METHOD

PROBLEM TO BE SOLVED: To provide a gas cleaner, a magnetic apparatus and a gas cleaning method, which can surely remove harmful matter from a gas after being burned. SOLUTION: The gas cleaner 11, having an inlet 11a for introducing an exhaust gas (a gas) containing the harmful matter after heat treatment into the gas cleaner and an outlet 11b for discharging the gas outside, has a passage part 38 in which a plurality of upward facing passages 35, which stretch in the gravity direction and introduce the exhaust gas flew in from the inlet 11a toward downward, and a plurality of downward facing passages 36, which stretch in the opposite gravity direction and introduce the exhaust gas toward upward, are communicated each other alternatively lining in a horizontal direction while sandwiching partitioning plates 37, a liquid spraying part 40 which is arranged above the downward facing passages 35, respectively and sprays a water (a cleaning treatment liquid) 39 downward, and a storage part 41 in which the water 39 falling down along the downward passages 35 is stored. The downward facing passages 35 and the upward facing passages 36 are communicated above the liquid surface of the storage part 41. COPYRIGHT: (C)2009,JPO&INPIT
