Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Below in conjunction with specific embodiment, realization of the present invention is described in detail.
As shown in Fig. 1 ~ 2, it is a preferred embodiment provided by the invention.
The present embodiment provides miniature ozone to wash away device 1 to be used in air-quality monitoring system, and certainly, it also can be used in miscellaneous equipment, is not limited to the utilization in the present embodiment.
Miniature ozone is washed away device 1 and is comprised lower cover 17, middle pipe 13 and upper cover 11, wherein, in middle pipe 13, there is cavity 131, this cavity 131 runs through the both sides of middle pipe 13, upper cover 11 and lower cover 17 are connected on the both sides of middle pipe 13, and close the opening of middle pipe 13 both sides, thus between upper cover 11, middle pipe 13 and lower cover 17 three, surround formation cavity volume.Upper cover 11 is connected with air inlet pipe, and this air inlet pipe is communicated with cavity volume, and lower cover 17 is connected with escape pipe, and this escape pipe is communicated with cavity volume, and like this, air inlet pipe, cavity volume and escape pipe are sequentially communicated with, and form the gas circuit that this miniature ozone washs away device 1.
In above-mentioned cavity volume, be respectively equipped with screen pack 15 and carrier 16, the axial direction of pipe 13 in edge, screen pack 15 and carrier 16 are arranged in stacked respectively, and carrier 16 is provided with ozone washs away catalyst, like this, the gas entered by air inlet pipe, after entering cavity volume, respectively by screen pack 15 and carrier 16, under the ozone in screen pack 15 and carrier 16 washs away the effect of catalyst, can be oxygen by the ozone reduction in gas, thus realize the object washing away ozone in gas, make from escape pipe gas be out gas not containing ozone.
Because above-mentioned carrier is porous carrier 16, wherein there is certain gap, thus can ensure that gas is when passing through wherein, larger pressure drop can not be caused in the both sides of carrier 16, thus ensure that this miniature ozone washs away pressure and the flow of gas circuit in device 1, ensure that higher ozone washs away efficiency, and compact conformation, volume is little.
