The invention discloses a pollution purifier for indoor decoration. According to the technical scheme, the pollution purifier includes an air extractor and a treatment barrel. An air outlet of the airextractor is connected with an air inlet pipe which extends into the bottom of the treatment barrel, and the treatment barrel is filled with treatment liquid. The treatment liquid comprises, by weight, 50-60 parts of water, 15-20 parts of modified tourmaline powder, and 60-70 parts of emulsifying wax. The air extractor can extract indoor air into the treatment barrel, air floats up and passes through the treatment liquid, formaldehyde is decomposed into carbon dioxide and water through negative ions, and therefore the treatment liquid can degrade formaldehyde continuously. Compared with a physical adsorption method, the treatment effect of the pollution purifier for indoor decoration is better.

The invention discloses a novel efficient formaldehyde catalyzing material and a digital display formaldehyde purifier prepared from the same. The novel efficient formaldehyde catalyzing material comprises a carrier and a formaldehyde catalyzing coating coated on the carrier, the carrier comprises a non-woven fabric layer and a composite fabric layer which are fixed together, and the formaldehydecatalyzing coating is prepared from the following raw materials: high-porosity manganese oxide fiber microspheres, methylglycine proline, an adhesive, nano titanium dioxide, permanganate, distilled water, a defoaming agent and a dispersing agent. The preparation method of the high-porosity manganese oxide fiber microspheres comprises the following steps of: twisting and gathering manganese oxide fiber membranes with a width of 1.5m and disorderly distributed internal fibers to form manganese oxide fiber bundle strips, then performing cutting off and extrusion to form the porous structure nanofiber microspheres. Due to the fact that a large number of micropores exist in the surfaces and the interiors of the high-porosity manganese oxide fiber microspheres in the coating, the efficient formaldehyde catalyzing material can rapidly adsorb formaldehyde in the air and undergo catalytic decomposition, and the formaldehyde removing rate is high.

The invention discloses a scavenger with an efficient formaldehyde purifying function.
