Abstract

The invention discloses an ozone room temperature decomposition honeycomb module and a preparation method thereof. A conventional aluminum honeycomb is taken as a carrier, deionized water, organic manganese salts, organic nickel salts, alumina powder, pseudo-boehmite, and a film forming agent are mixed and homogenized to prepared catalyst slurry, and the catalyst slurry is sprayed on the carrier,and then is blown, dried, and burned to obtain a finished product. The ozone room temperature decomposition honeycomb module has the characteristics of lightness, corrosion resistance, low wind resistance, high decomposition efficiency, and long service life. The preparation of the module is simple, convenient, and environmentally friendly. No gas pollutant such as oxynitride, oxysulfide, or the like, or sewage is discharged. The prepared honeycomb module can be applied to catalytic decomposition of ozone in the air; at a temperature of -10 to 40 DEG C, under a humidity of 30-98 RH%, the ozoneconcentration can be reduced to 0.02 mg / m3 from 1-20 mg / m3; the ozone degradation rate is more than 98%; and the honeycomb module can effectively remove ozone for more than 3500 hours.

Description

technical field [0001] The invention relates to the technical field of room temperature catalysis and air pollution control, in particular to an ozone room temperature decomposition honeycomb module and a preparation method thereof. Background technique [0002] Studies have shown that the long-term harm of ozone-based photochemical oxidants to the human body is mainly reflected in the damage of body membranes (including various organ tissues and cell membranes), the decline of heart function, the oxidation of elastic fibers in tissues, and the premature aging of the body and the shortening of life span. . Therefore, the World Health Organization has established a safety standard for ozone: the maximum concentration allowed in an 8-hour working environment should be less than 0.10ppm. In daily life, if there are no treatment measures for electrostatic copiers, printing machines, laser printers, fax machines, electrostatic precipitators, ozone disinfection cabinets, vacuum u...
