[0002] Expanded vitrified microspheres are an inorganic glassy mineral material. Vitrified microspheres are made by preheating perlite ore in a vitrified microsphere expansion furnace, and then instantaneously calcining and expanding it to form a white granular material with a honeycomb structure inside. They are irregular spherical particles with an internal porous cavity structure, a closed vitrified surface, a smooth luster, stable physical and chemical properties, and excellent properties such as light weight, heat insulation, fire resistance, high and low temperature resistance, aging resistance, and low water absorption. They can replace many traditional lightweight aggregates such as fly ash floating beads, glass microspheres, expanded perlite, and polystyrene particles in different products. However, the high-temperature exhaust gas generated in the expansion furnace contains a large amount of dust and toxic gases. If these exhaust gases are directly discharged into the air, it will cause environmental pollution. Therefore, an exhaust gas treatment device is required to treat the exhaust gas before discharging it.

[0003] The existing technology has the following problems:
