BAG FILTER WITH COOLING PART

PROBLEM TO BE SOLVED: To save a space and to reduce an initial cost of exhaust gas treatment equipment by eliminating an exhaust gas cooling part such as a water spray temperature reducing tower or the like, additionally required in a conventional method. SOLUTION: In a bag filter apparatus for cooling exhaust gas containing particles of soot to perform dust collection, cooling parts 2, each of which consists of a cooling means 7 for cooling the exhaust gas and a cooling space 8, are arranged to at least two side surfaces of a dust collection part 1 comprising a plurality of filter cloths 4, and the cooling part 2 and the dust collection part 1 are partitioned by a partition plate 10 having length equal to or larger than the length in the longitudinal direction of each filter cloth 4 and the exhaust gas, which is cooled by the cooling part 2 through the gas flow channel 17 under the partition plate 10, is introduced into the dust collection part 1.
