Exhaust gas treatment method, and exhaust gas treatment device

Abstract

This exhaust gas treatment method is characterized by involving a step for supplying ozone and a first liquid, which is water or an aqueous solution, into an exhaust gas that contains NOx and that is 150 DEG C or higher, and for generating a first mist, in which the water droplets of the first liquid are suspended, in the exhaust gas containing ozone gas. This exhaust gas treatment method may also involve a step for generating, in the exhaust gas that passed through the first mist, a second mist by spraying a second liquid which is a reducing agent aqueous solution.

Description

technical field [0001] The invention relates to a waste gas treatment method and a waste gas treatment device. Background technique [0002] Glass products such as glass bottles are produced by melting raw materials such as quartz sand, soda ash, lime, etc., and cullet obtained by crushing empty bottles, etc., with a burner in a furnace (about 1500°C), and molding the molten glass. The combustion exhaust gas containing the combustion exhaust gas from the burner and the components derived from the molten glass is discharged from the melting furnace in which the glass is melted. The combustion exhaust gas discharged from the furnace contains air pollutant NO x or SO x , these pollutants need to be removed from the combustion exhaust before it is released into the atmosphere. In addition, since the combustion exhaust gas contains SO from glass raw materials x , Adhesive components and other catalyst poisoning components, therefore, it is difficult to use the conventional NO...
