Description
Technical field
The invention belongs to ozonizer technical field, be specifically related to a kind of ozonizer containing the micro-nano catalyzer of solid.
Background technology
Ozone has the good characteristics such as extremely strong oxidisability and non-secondary pollution, and being therefore widely used in the aspects such as drinking water disinfection, sewage disposal, off gas treatment, is the mankind's " desirable omnipotent green Strong oxdiative medicaments ".But energy consumption is excessive in ozone production process, productive rate is too low, and cost intensive hinders the large-scale promotion application of ozone and further developing of ozone oxidation industry.Current commercial ozonizer mainly adopts dielectric barrier discharge form, and yield of ozone is about 70g/kWh(air source) and 140g/kWh(source of oxygen), far below theoretical value 1226g/kWh.In recent years, in order to improve yield of ozone, domestic and international many scholars have successively carried out large quantifier elimination to discharge type, electrode form, dielectric substance, discharge power supply, discharge chamber structure etc., although achieve larger progress, how to improve yield of ozone further still urgently to be resolved hurrily.
For improving yield of ozone further, some scholars attempt seeking suitable gas catalyst, to oxygen rich source from source of oxygen and air source, then add other gas catalyst in source of the gas.The literature survey of system finds, adds gas and mainly contains following three types: the 1) gas of not attract electrons, as rare gas element and N
2; 2) oxygen-containing gas of attract electrons, as CO
2, H
2o and NO
x; 3) the oxygen-free gas of attract electrons, as methyl halide and SF
6.But, make a general survey of these gas catalysts, although have portion gas as SF
6can improve ozone concn and yield of ozone, but economically set out, none is with practical value, makes us feeling sorry.Undeniable, in traditional ozonizer process, the impact of surface reaction almost can be ignored.The surface reaction approach of this unheeded " can ignore ", from another one catalyzer angle---solid catalysis, fully excavates, develops efficient solid catalysis ozonizer by contriver.
