Claim 8:
9. The apparatus of claim 1, wherein the lower end trapping unit (33) is connected to the lower portion of the intermediate trapping unit (32) and comprises an outer periphery trapping plate part (331), an intermediate trapping plate part (332), and an inner trapping plate part (333) which have a plurality of gas holes formed in surfaces thereof and are disposed in multiple stages,
wherein the lower end trapping unit (33) prevents the gas, which has experienced the trapping reaction in the inner region and the outer region of the intermediate trapping unit (32), from flowing downward directly into the gas discharge port (13a) provided on a lower plate of the housing,
wherein the gas is guided toward the inner side from the outer periphery, such that the trapping reaction is finally performed, and
wherein the flow of the gas is guided so that the gas flows into the upper side of the gas discharge port (13a) protruding upward from the central portion of the lower plate of the housing and then flows downward.
