[0043] The utility model discloses a kind of deodorization modules 100, and the ozone generator 110 generated by discharge method ozone is provided with the ozone generator 110, for the active oxygen generation part that active oxygen is decomposed into ozone and the power supply 130 of ozone generator 110 power supply;Ozone generator 110 includes discharge component 111, opposite polar plate 112.It is specific that discharge component 111 is connected to the negative electrode of power supply 130, opposite polar plate 112 is connected to the positive electrode of power supply 130, and opposite polar plate 112 is provided with the flowing space for the air fluid to flow between discharge component 111;Active oxygen generation part includes ozone decomposition catalyst 140.It is specific that ozone decomposition catalyst 140 is arranged on the outer surface of opposite polar plate 112 near discharge component 111 side, for the ozone decomposition to generate active oxygen;Wherein, opposite polar plate 112 is formed with the arc-shaped velocity boundary layer 120 that is bent to opposite polar plate 112 on the side of flowing space near opposite polar plate 112, and discharge component 111 is arranged on the side of arc-shaped velocity boundary layer 120 near opposite polar plate 112.

[0044] Specifically, the closer to opposite polar plate 112, the less ozone is affected by main flow, and the slower the flow rate is, and the easier ozone is contacted with ozone decomposition catalyst 140 (the contact referred in the embodiment of the utility model includes that ozone is captured by ozone decomposition catalyst 140), in the present scheme, ozone is generated on the side of arc-shaped velocity boundary layer 120 near opposite polar plate 112 in ozone generator 110, in the direction of air fluid flow, ozone moves at second flow speed lower than first flow speed of air fluid, under the action of ion wind generated by discharge component 111, ozone moves towards ozone decomposition catalyst 140, so that ozone is contacted with ozone decomposition catalyst 140, so that ozone is decomposed to generate active oxygen.

[0045] Further, as Figure 2As shown, the first end portion of the discharge component 111 close to the opposite electrode plate 112 is bent to the side of the opposite electrode plate 112 close to the discharge component 111. The present application promotes the development of the arc-shaped velocity boundary layer 120 by bending the first end portion of the discharge component 111 close to the opposite electrode plate 112 to the side of the opposite electrode plate 112 close to the discharge component 111, thereby increasing the arc-shaped velocity boundary layer 120, further reducing the influence of the air flow on the ozone generated by the ozone generator 110, and further improving the production efficiency of the active oxygen, thereby improving the deodorization effect of the deodorization module 100.

On the other hand, the catalyst is coated or mechanically fixed on the outer surface of the opposite electrode plate 112 to ensure that the ozone decomposition catalyst 140 can fully contact with the ozone, thereby improving the decomposition efficiency of the ozone decomposition catalyst 140 on the ozone, and further improving the production efficiency of the active oxygen.

[0049] Further, the specific surface area of the ozone decomposition catalyst 140 provided on the opposite electrode plate 112 is greater than 250 m 2 / g. The present application increases the area of the ozone decomposition catalyst 140 and the ozone by setting the specific surface area of the ozone decomposition catalyst 140 provided on the opposite electrode plate 112 to be greater than 250 m 2 / g, thereby further improving the decomposition efficiency of the ozone decomposition catalyst 140 on the ozone, and further improving the production efficiency of the active oxygen.
