The above prior art is regulated,
They are used in combination according to needs. Until now, no consideration has been given to simultaneously treating solid harmful components of dust and gaseous harmful components of hydrogen chloride, sulfur oxides, nitrogen oxides, mercury and organochlorine compounds. There is a problem with processing. In particular, with regard to the removal of mercury and organochlorine compounds, the technology that puts activated carbon into the flue and repairs it with a downstream bag filter uses activated carbon that has adsorbed those harmful components in dust generated in large quantities in a fluidized bed incinerator. And its separation is difficult. Further, the technology of decomposing nitrogen oxides and organochlorine compounds by providing a catalyst tower downstream of a bag filter requires new equipment, which not only increases the equipment cost of a refuse incinerator but also increases the installation area.
An object of the present invention is to reduce the amount of dust contained in exhaust gas, hydrogen chloride,
The simultaneous removal of sulfur oxides, nitrogen oxides, mercury and organochlorine compounds with a functional bag filter.
