본 발명은 보일러용 배기장치에 관한 것으로, 외면에 축관부를 형성한 배기파이프를 구비하고, 내주면에 패킹홈을 형성한 연도 내로 배기파이프를 삽입 결합하며, 연도의 패킹홈에 밀폐패킹을 삽입 결합하여 연도와 배기파이프 외면 사이의 틈새를 밀폐하고, 축관부에 링부재를 삽입 결합하되, 밴드부로 링부재를 감싸 조임으로써, 밴드부가 링부재에 걸림 고정된 상태에서 배기파이프와 연도 사이를 조임 연결하여, 밴드부가 배기파이프와 연도 사이에서 상, 하로 유동되는 것이 방지된다. 본 발명에 따르면, 배기파이프의 축관부에 삽입된 링부재에 밴드부가 걸림고정되어, 밴드부가 상, 하로 유동될 우려가 없고, 밴드부의 유동 방지로 배기파이프와 연도 사이가 밴드부에 의해 견고하게 연결된 상태로 유지되며, 연도 내로 배기파이프 진입시 링부재에 연도 하단이 맞닿아 배기파이프의 진입 깊이를 제한할 수 있으며, 또한, 연도 하단이 링부재에 떠받쳐져 그 지탱력이 견고하고, 복수의 축관부 중 링부재의 삽입 위치에 대응하여 연도의 높이가 조절되며, 이에따라, 제품의 신뢰성이 향상되는 장점이 있다.

Boiler flue bypass flue gas baffle shaft dust preventing device

一种锅炉烟道旁路烟气挡板轴防尘装置，包括挡板轴、保护罩、防尘毡圈、挡板边支架、防尘毡条，挡板轴中部与挡板叶片焊固，保护罩前端开口，保护罩后端与挡板叶片焊固，保护罩前端的开口处一半有丝孔，另一半有光孔，保护罩前端开口处，用螺栓紧固，保护罩与挡板轴轴头间有防尘毡圈，保护罩外径与挡板边支架上的轴承内环配合固定，挡板边支架与旁路烟道壁配合固定，挡板边支架等距有四个轴承孔，轴承外环与挡板边支架的轴承孔内径配合，挡板边支架两侧有凹槽，与两侧凹槽配合的有防尘毡条。避免旁路烟气挡板叶片轴的卡、涩，有效阻止部分净烟气重新吸入烟气脱硫系统或原烟气直接排入烟囱。并能减少升压风机容量的余量，降低升压风机的运行成本。

Connection structure for pipes of a downward combustion type boiler having inhalation combination exhalation fan device

본 발명은 흡기겸용 배기팬기구를 갖춘 하향식 보일러의 관연결구조에 관한 것으로, 공기유입구(20a)와 배기가스 배출구(20b) 및 배기관(70)을 상호 적절하게 연결하는 관연결부재(90)을 매개로, 배기가스 배출구로 배출되는 배기가스가 충분히 냉각되면서, 흡입되는 공기가 배기가스의 잠열에 의해 충분히 가열되는 구조로 되어, 연소실에서의 혼합가스의 연소가 촉진되고, 배기관의 온도가 적정온도 이하로 낮아지도록 된 것이다. The present invention relates to a pipe connection structure of a top-down boiler having an intake and exhaust fan mechanism, and provides a pipe connection member 90 for properly connecting the air inlet 20a, the exhaust gas outlet 20b, and the exhaust pipe 70 to each other. As a result, while the exhaust gas discharged to the exhaust gas outlet is sufficiently cooled, the intake air is sufficiently heated by latent heat of the exhaust gas, so that combustion of the mixed gas in the combustion chamber is promoted, and the temperature of the exhaust pipe is at an appropriate temperature. It will be lowered below.
