Abstract

The invention discloses a rare earth material industrial exhaust gas purifying agent based on a perovskite-type composite oxide. The rare earth material industrial exhaust gas purifying agent comprises, by weight, 8 to 20% of grape polyphenol, 4 to 8% of lysine, 5 to 10% of titanium dioxide, 0.01 to 0.5% of a penetrant, 0.01 to 1.0% of a pH adjustment agent, 10 to 20% of a perovskite complex oxide, 1.0 to 2.0% of activated carbon, 0.1 to 0.5% of a humidifier and the balance of purified water. Through use of the perovskite complex oxide as a cocatalyst for modifying the perovskite complex oxidization photocatalysis, the sensibilization, activation and stability of the perovskite complex oxide are improved. Through use of the nano-sized titanium dioxide, under ultraviolet light action, strong catalytic degradation functions are produced and the toxic and harmful gas in air is effectively degraded.

Description

technical field [0001] The invention relates to a rare earth material industrial waste gas purifier, in particular to a rare earth material industrial waste gas purifier based on a perovskite type composite oxide. Background technique [0002] The rare earth elements are numerous, including 15 lanthanides from lanthanum to lutetium. If scandium and yttrium are included, there are as many as 17 elements. Since the rare earth element has a special outer electron structure, as the central atom of the complex, it has various coordination numbers from 6 to 12. The variability of the coordination number of rare earth elements determines that they have "residual atomic valence". Because there are 7 back-up valence electron orbitals that have the ability to form bonds, which play the role of some kind of "backup chemical bond" or "residual atomic valence". This ability is exactly what the catalyst must have. Therefore, rare earth elements not only have catalytic activity themsel...
