WATER WARMER HAVING SILENCER AND PURIFIER OF EXHAUST GAS

摘要

PURPOSE:To silence and purify a waste gas and make possible obtaining of hot water by introducing the high-temp. waste gas into the upper and lower double eccentric spiral passages in a bottomed lower cylindrical body, then allowing the same to ascend and flow in the multiple vent pipes in an annular cooling water chamber. CONSTITUTION:A high-temp. waste gas is conducted from a lead-in pipe 34 into the upper and lower double spiral eccentric passages in a bottomed lower cylindrical body 2, where it is separated of dusts, fire powder, oil contents, water contents, etc. after which it is sent into the dust accumulating part 5 in the bottom. The high- temp. waste gas after the separation is flowed upward into the central hole part 42 of an annular cooling water chamber 39 through a gas rising cylinder 18, thence it is allowed to descend in the annular space 39 on the outer side of the water chamber 39 in the downward direction and further the waste gas having decended is flowed upward diffusively in the multiple vent pipes 42 penetrated in the water chamber 39. The high-temp. exhaust gas is sufficiently cooled in this way and is released from a waste cylindrical part 49. The waste gas is decreased and silenced by this cooling, and this makes possible the continuous taking out of hot water from a pipe 41.
