A harmful chemical substance and a harmful gas purification device and a water purification device by a solar light (ultraviolet ray) synthesis action using a porous sintered body as a catalyst

摘要

purpose :;Among the waste materials that are generated in large quantities as waste in the casting industry, the use of non-recyclable fine powder (dust DUST) and zinc oxide (ZnO) powder produced in low frequency furnace is used to produce a high porosity, austenitic It is an object of the present invention to provide a device for purifying harmful substances and noxious gas by a photosynthesis action using a ceramic sintered body having high porosity and a catalyst for sintering the same.;Configuration:;The fine powder (DUST) generated from the waste grinding stock and the zinc oxide (ZnO) powder generated from the low frequency furnace are mixed well, water is added, and the mixture is mixed well to dry and sinter the molded product. The resulting photocatalyst of the porous ceramic sintered body It is a purifying device that combines ultraviolet projection devices.
