A smoke exhaust device is attached to the top of the furnace to guide the smoke generated from the mixing furnace to the outside. Conventionally used smoke exhaust devices are mainly formed by a smoke exhaust duct attached to a furnace lid that covers the upper surface of a mixing furnace. The middle part of the smoke exhaust duct is connected separately so as not to interfere with the tilting of the furnace,
The lower smoke exhaust duct is erected approximately perpendicularly to the furnace cover so as to be tilted together with the furnace. The flue gas inside the furnace is led to the flue gas treatment equipment such as a bag filter through the smoke exhaust duct, and
After being treated with m, it is released into the atmosphere.
ところが従来の排煙装置は、炉の傾転時に炉上面に炉に
装着されている下側の排煙ダクトが炉と一体に傾転する
際、上側の排煙ダクトから外れて排煙が炉の周囲に放出
され、炉周囲の環境を損なう問題がある。However, with conventional smoke exhaust devices, when the lower smoke exhaust duct attached to the top of the furnace tilts together with the furnace, it comes off from the upper smoke exhaust duct and exhaust smoke flows into the furnace. There is a problem that it is released into the surrounding area and damages the environment around the furnace.
本発明は、炉の傾転時にも排煙が漏出しない排煙設備を
