A kind of catalysis type oil fume pump exhaust purifier that the utility model provides, it is characterized in that, this device comprises air inlet pipe, blast pipe, air exhauster and catalytic converter, wherein, air inlet pipe is connected with the front end of catalytic converter, blast pipe is connected with the rear end of catalytic converter, and blast pipe also is connected with air exhauster.
In order to implement the utility model better, fan housing can be installed at the port of air inlet pipe; Junction at air inlet pipe, blast pipe and catalytic converter can be installed mozzle respectively; Airintake direction at catalytic converter can be installed the oil removal net, in its bottom oil trap can be installed; The heat tracing layer can be equipped with in outside at catalytic converter; The heat tracing layer is made of heating wire, and external electric switch; In mozzle, the deflector of being made up of the concentric circles dividing plate can be installed; Catalytic converter is interconnected to constitute by housing and the honeycomb ceramic carrier that scribbles catalyst; In honeycomb ceramic carrier, also be equipped with a gas passage.
The utility model compared with prior art has following advantage and beneficial effect:
1. the utility model can be installed in the airduct or flue of the original smoke exhaust ventilator in kitchen, also can directly utilize original blower fan, installs very easy.
2. oil removal efficiency of the present utility model can reach more than 90%, and has reached national up-to-date kitchen fume discharge standard.
3. oil smoke can directly be discharged after the utility model is handled, and the oil smoke material is catalytically converted into carbon dioxide and water, can not produce secondary pollution, has thoroughly solved the pollution problem of oil smoke to atmosphere.
4. the utility model is simple in structure, volume adequacy, and pressure drop is not high, compact conformation, work noise is low, and operation maintenance is convenient, installs, dismantles and clean all to be easy to.
5. the utility model operating cost is low, is fit to very much family expenses or medium and small hotel, dining room use.

(5) specific embodiment
As shown in Figure 1, the fan housing 3 of collecting oil smoke is installed in the top of kitchen range 1 and kitchen range stove 2, one end of air inlet pipe 4 links to each other with fan housing 3, the other end is connected with catalytic converter 7 with oil removal net 6 by mozzle 5, and catalytic converter 7 is connected with blast pipe 12, air exhauster 13 by the mozzle 11 of the other end.The bottom of catalytic converter 7 is equipped with drawer type oil trap 8, and external stability has heat tracing layer 9 and electric switch 10.
Shown in Fig. 2,3,4, catalytic converter 7 is made up of housing 14 and the honeycomb ceramic carrier 15 that scribbles catalyst, a gas passage 16 is arranged in honeycomb ceramic carrier 15, heat tracing layer 9 is made of heating wire 17, and external electric switch 10, the deflector of being made up of the concentric circles dividing plate 18 is installed in mozzle 5 and 11, in the slit of heat tracing layer 9, adds mineral wool 19.It is 5% CuO, 5% NiO, 5% CoO, 25%MnO that the activity of such catalysts component can be selected for use by mass percent
