Abstract

The invention relates to the technical field of ozone catalysts, in particular to a method for preparing a catalyst for quickly decomposing ozone in the air and application. The ozone catalyst is prepared by preparing manganese dioxide and glycerol into a preparation in a certain ratio, selecting an air filter material such as sponge, a netlike or fibrous filter screen or the like as a carrier and soaking the carrier to adsorb the prepared preparation. The catalyst is used for decomposing and filtering the ozone in the air, is simple, convenient, low in cost, quick, efficient and durable, and can be widely applied to air purifiers, electrostatic copying machines, laser printers, electrostatic dust collectors, sterilization cabinets and other electric equipment adopting high-voltage discharge.

Description

The catalyst preparation method and the application of ozone in a kind of quick decomposition air
[technical field]
The present invention relates to the technical field of ozone catalytic agent, specifically a kind of preparation of catalysts method and application that is used for decomposing fast air ozone is used for eliminating the harm that air exists excessive concentrations ozone to cause human body.
[background technology]
Ozone has extremely strong oxidisability, uses so all have at aspects such as deodorizing sterilizing, wastewater treatment, air cleanings comparatively widely.Yet the ozone of excessive concentrations has damaging effect to health, and therefore, ozone also is the pollutant that should control in ambient air and the room air.
Known technology has the ozone catalytic agent of transition metal series, noble metal series, compounding ingredients series or the like type at present, the carrier of these ozone catalytic agent mostly adopts materials such as active carbon, gama-alumina, molecular sieve, reticular polyurethane and cordierite, all take with preparation preparation, carrier impregnation in the making, cure drying, this pattern of high-temperature roasting is the series of processes of standard, the product of making all exists shortcomings such as complicated process of preparation, the product moisture-proof is poor, service life is short.
The present invention adopts cheap manganese dioxide and common glycerine, directly mix according to a certain percentage, be mixed with catalyst, select for use selected air filting material such as the big sponge of ventilation, netted, fibrous filter screen as carrier again, by simple carrier impregnation, both adsorbed, drain and to finish making.Because manganese dioxide is powder, have certain toxicity, not waft in the air with air-flow in order in use not make manganese dioxide powder, prior art is the bonding component that relies in the prescription, by high temperature sintering, manganese dioxide powder is cemented on the carrier.The present invention is with the direct mix manganese dioxide powder of glycerine, because glycerine has good hygroscopicity, can absorb airborne moisture in a large number, so just can make carrier and be adsorbed on manganese dioxide powder on the carrier to remain moisteningly, manganese dioxide powder just can not suffer with the air-flow air that wafts yet in the use.Ozone has characteristic soluble in water, and ozone can dissolve in the moisture of glycerine absorption, with manganese dioxide generation catalytic reaction fast.Owing to do not contain bonding component in the prescription, improved the efficient of manganese dioxide catalytic reaction again.
[summary of the invention]
The objective of the invention is to realize: with a certain proportion of glycerine and the direct mix of manganese dioxide powder by following method, the air filting material that sponge, netted, fibrous filter screen etc. are selected immerses in the mixture, extruding a little, stir, treat that fully take out the absorption back, place and drained too much glycerine in 24 hours and get final product.Manganese dioxide has good quick catalysis reagentia to the ozone of strong oxidizing property, generate oxygen by catalytic reaction to ozone, glycerine has good hygroscopicity, can absorb airborne moisture in a large number, remain moistening with regard to the manganese dioxide powder that makes carrier and be adsorbed on the carrier like this, manganese dioxide powder just can not waft in the air the two no conflict effect together that cooperatively interacts in the use with air-flow.Has good infiltration adsorption function as air filting materials such as the sponge of carrier, netted, fibrous filter screens, be adsorbed the manganese dioxide powder of infiltration with glycerine, can distribute equably attached to each top layer of filtering material, keep to greatest extent than the table contact area with air, unless long-term use sucks too much dust and causes filtering material to stop up, otherwise the problem that does not just exist catalyst ageing to lose efficacy.
Catalyst formulation of the present invention is shown in table 1
Table 1:
Amounts of components (%)
Manganese dioxide (powder) 5-90
Glycerine 10-95
Catalyst better formula of the present invention is shown in table 2
Table 2
Amounts of components (%)
Manganese dioxide (powder) 50-60
Glycerine 40-50
The catalyst of ozone is prepared as follows in the present invention's a kind of quick decomposition air: in a suitable containers, pour the manganese dioxide powder of 5-90% into, the glycerine of 10-95%, stir into pulpous state, the air filting material that sponge, netted, fibrous filter screen etc. are selected immerses in the mixture, and extruding is a little stirred, treat that fully take out the absorption back, place and drained too much glycerine in 24 hours and get final product.
The catalyst of ozone is used for decomposing airborne ozone fast in the present invention's a kind of quick decomposition air, is used for eliminating the harm that air exists excessive concentrations ozone to cause human body.The present invention has easy, low-cost, quick, efficient, lasting effect, can be widely used in air cleaner, the electric equipment of Xerox, laser printer, electrostatic precipitator, Sterilization disinfectant cabinet and other employing electrion.
[specific implementation method]
Catalyst optimum formula of the present invention is shown in table 3

Amounts of components (%)
Manganese dioxide (powder) 50
Glycerine 50
The concrete preparation method of the present invention is as follows: in a suitable containers, pour 5 kilograms of manganese dioxide powders into, 5 kilograms of glycerine, stir into pulpous state, can get the mixture about 10 kilograms, the air filting material that sponge, netted, fibrous filter screen etc. are selected immerses in the mixture, extruding a little, stir, treat that fully take out the absorption back, place and drained too much glycerine in 24 hours and get final product.
