Abstract:
To provide an exhaust gas treatment apparatus where a precoat layer is formed on the filter cloth of a filtration type dust collection device 3 cleaning an exhaust gas exhausted from an incinerator 1 with a chemical agent neutralizing a sour gas in the exhaust gas and the chemical agent can be efficiently attached on the filter cloth while suppressing equipment addition as much as possible even when the chemical agent is hardly efficiently attached on the filter cloth at the forming of the precoat layer.SOLUTION: In an exhaust gas treatment apparatus, a filtration amount is made larger than a specified value Z by introducing cooling air to an upstream side from a chemical agent supply position at the inlet of a filtration type dust collection device 3 when the amount (filtration amount) of an exhaust gas passing the filtration type dust collection device 3 is less than the specified value Z at the forming of a precoat layer.SELECTED DRAWING: Figure 2
