Description

Incineration flue gas composite purification filter device using water molecule filtration {Multi-Purifying Filter Apparatus Using Filtration Typed}

The present invention relates to an incineration combustion gas composite purification filter device using a water molecular filtration method, and more particularly, by adsorbing and filtering the exhaust gas of an incineration combustion facility by contact with water molecules by centrifugal force to fine particles contained in combustion exhaust gas. It relates to an incineration combustion gas composite purification filter device using a water molecule filtration method capable of reducing dust and efficiently removing harmful components.

In general, facilities that generate a large amount of incineration combustion gas, such as thermal power plants or waste incinerators, contain harmful air pollutants such as fly ash, acid gas and nitrogen oxides, heavy metals, dioxins, and volatile organic gases contained in combustion exhaust gas. As these pollutants must be treated below the regulatory level before being discharged into the atmosphere, harmful gas purification facilities are built and used.

Here, electric precipitators, bag filters, cyclones, and gravity precipitates are used as facilities to treat particulate pollutants such as fly ash among harmful gas purification facilities, and various reactive agents are used to treat acid gases. It is classified into wet method, dry method, and semi-dry method depending on whether moisture is used. Furthermore, as a method for removing nitrogen oxides, a selective catalytic reduction method, a selective non-catalytic reduction method, etc. are mainly used, and dioxins, heavy metals, and volatile organic compounds that are not removed even after passing through them are removed by methods such as adsorption towers and adsorbents. .

As a configuration for filtering out pollutants in these various harmful gas purification facilities, a purification filter device is installed and used in each facility.

As a prior art that has been disclosed in relation to a purification filter device used in a harmful gas purification facility as described above, Korean Patent Registration No. 1841019 (2018.03.22.) discloses environmentally harmful nitrogen oxides (NOx) during combustion, An incineration plant combustor generating high-temperature exhaust gas containing sulfur oxides (SOx) and dust, an exhaust gas line connected so that the high-temperature exhaust gas discharged from the incineration plant combustor can flow and be supplied, and the exhaust gas It is directly connected to the other end of the line and simultaneously processes the reduction of sulfur oxides (SOx), fine dust (PM-25) and nitrogen oxides (NOx) contained in the high-temperature exhaust gas supplied through the exhaust gas line. A flue gas processing unit having a ceramic filter, and a stack discharging clean gas purified through a plurality of ceramic filters of the flue gas processing unit to the outside. An exhaust gas treatment system for simultaneous treatment of fine dust and harmful gases generated in an incineration power plant capable of simultaneously reducing and reducing fine dust is known.

In addition, Korean Patent Registration No. 965912 (2010.06.24.) discloses an incinerator, a boiler connected to the incinerator, a cooling tower connected to the boiler and lowering the temperature of exhaust gas, connected to the cooling tower, and collecting pollutants. A dust collector for filtering, an exhaust tower connected to the filter and discharging exhaust gas to the outside, a first slaked lime injection unit for injecting highly reactive powder slaked lime between the cooling tower and the filter, and a front end or rear end of the boiler As configured to include an additional slaked lime injection unit for injecting highly reactive powder slaked lime, an incinerator exhaust gas purification system capable of significantly improving the final reaction efficiency while reducing the total amount of slaked lime is known.

However, in the case of the above prior art, since the exhaust gas emitted from industrial facilities such as thermal power plants, steel mills, incinerators, etc. contains a relatively large amount of fine dust, fine dust is additionally collected through filtering in the final stage after a predetermined smoke control process. It is released after removal. At this time, since the filter is blocked early due to a large amount of dust, there is a backflow phenomenon due to differential pressure, which increases maintenance costs due to frequent filter replacement, and there is a problem that the purification efficiency is remarkably low due to the deterioration of the filter function. .
