[0002] Flue gas is a mixture of gas and soot, and is the main cause of polluting the atmosphere in residential areas. The composition of flue gas is very complex. The gas includes water vapor, sulfur dioxide, nitrogen, oxygen, carbon monoxide, carbon dioxide, hydrocarbons, nitrogen oxides, etc. The soot includes ash of fuel, coal particles, oil droplets, and high-temperature pyrolysis products, etc. It seriously pollutes the environment and affects human health.

When dust overflows the sensor 30, it can remind the staff to replace it. This is a prior art and will not be described in detail. When the side wall of the smoke exhaust pipe 1 is rotatably connected to the rotating shaft 16, the rotating shaft 16 and the outer side of the driving shaft 6 are fixedly sleeved with a bevel gear 17, and the two bevel gears 17 are meshed with each other.
