Technical field

The present invention relates to air activating device technical fields, and in particular to a kind of air-activated composite material and its application.

Background technique

At work, fuel oil and air blend burning by a certain percentage and provide kinetic energy to engine automobile engine.So And due to incomplete combustion, serious energy waste is not only caused, it is exceeded to also cause exhaust emissions, seriously pollutes environment.With The implementation of " light-duty vehicle pollutant emission limitation and measurement method (Chinese 6th stage) " (GB 18352.6-1016), automobile Exhaust emissions requirement is tighter, and there is an urgent need to more effective energy-conserving and emission-cutting technology and devices.

Currently, such as catalytic converter, grain catcher vehicle exhaust after-treatment device belongs to treatment after pollution, emission reduction Effect is limited, is difficult to fully meet increasingly strict environmental requirement；Air-activated pretreating device can reach simultaneously energy conservation and subtract The purpose of row, but existing air activating device effects of energy saving and emission reduction is not significant enough, it therefore, can be from the material and knot of air activating device Structure design sets about further increasing the effects of energy saving and emission reduction of air activating device.

Summary of the invention

It is an object of the invention to provide in place of overcome the deficiencies in the prior art a kind of air-activated composite material and its Using.

To achieve the above object, the technical solution adopted by the present invention is as follows:
