TECHNICAL FIELD The present invention relates to an apparatus for treating harmful substances containing white smoke, and more particularly, to an apparatus for treating harmful substances containing white smoke for use in a power plant for removing harmful substances including white smoke from a gas discharged from a power generating plant during power generation.

Various types of gases, including smoke or water vapor, can be discharged through a discharge means such as a chimney during the operation of a power plant such as a thermal power plant or a fuel cell power plant. Contaminants may be contained in such exhaust gases, and may be in the form of white smoke during the discharge process depending on the surrounding environment. A gas containing water vapor generated as a result of reaction can be discharged from a hydrogen fuel cell power plant that directly converts chemical energy generated from a reaction between a raw material containing hydrogen and oxygen in the air into electricity using a power converter. When the temperature of the exhaust gas containing water vapor is low, the water vapor may be in the form of white smoke. White smoke can be generated from a power plant or other power plant. It is advantageous that the white gypsum itself is harmless but not treated in advance and discharged to the outside. For example, in the case of white smoke in the form of vapor, it is advantageous to be made of liquid and discharged separately. On the other hand, the discharged gas may contain foreign matter or chemical components such as fine dust, and it is advantageous that such foreign matter or chemical substance is removed in advance before being discharged.
