Quenching type smoke mixed chamber apparatus

Disclosed in the utility model is a quenching type smoke mixed chamber apparatus comprising a mixed chamber body. A smoke inlet is formed in one end of the mixed chamber body and is communicated with a boiler smoke exhaust outlet; and a smoke outlet is formed in the other end of the mixed chamber body and is communicated with a high-temperature flue gas pipeline. A cooling water mechanism is arranged at the mixed chamber body and thus indoor smoke and the cooling water form a reversed flow arrangement mode, thereby forming a membrane type internal cooling structure. Moreover, a cold fog device that is used for spraying atomizing cooling water into the indoor space uniformly is also arranged at the smoke inlet side of the mixed chamber body. The atomizing cooling water is sprayed into the smoke inlet side of the mixed chamber to cool the high-temperature smoke rapidly, thereby reducing the smoke temperature and preventing coking of the smoke exhaust outlet/mixed chamber. In addition, cold smoke can enter the s
