The specific embodiment

Below in conjunction with embodiment, the utility model is further specified, following embodiment is illustrative, is not determinate, can not limit the protection domain of the utility model with following embodiment.

A kind of lower-discharging type kitchen range air outlet fume purifying mechanism; Shown in Fig. 1～6; The innovation of the utility model is: comprise tube connector 1, adsorption tube 4 and HV generator 6; The upper end of tube connector is through the air outlet of screw thread or buckle connection blower fan, and the lower end of tube connector is connected with adsorption tube upper end one through the transition conduit 3 of a taper type, and this adsorption tube lower end is through flange 7 connecting bends 9 upper ends; An electrode 2 of said HV generator stretches in tube connector or the transition conduit, and another electrode 5 of this HV generator connects the conduction filter core of installing in the adsorption tube 15.

The diameter A of tube connector is 160～180 millimeters; The diameter B of adsorption tube is 200～220 millimeters; Because the diameter of adsorption tube is greater than the diameter of tube connector, speed was reduced to 6 meters of per seconds by 10 meters of per seconds when flue gas flow through, and helped the processing of the impurity in the later stage flue gas after velocity of flue gas reduces.

In the present embodiment, the negative pole of HV generator stretches in tube connector or the transition conduit, and the positive pole of high-voltage electrostatic generator connects the conduction filter core of installing in the adsorption tube.After discharge head 10 discharges that install the negative pole end; Plasma that produces and the particulate generation inelastic collision in the flue gas; Make flue gas carry negative electrical charge; The particle of these negative electrical charges receives the attraction of the conduction filter core that has positive charge during through adsorption tube, all accumulates on the conduction filter core and converge to be cold oil 11, and cold oil trickles downwards and is collected along the conduction filter core.
