Get into first clean room 31 through the import of purifying box 3 one end, plasma polar plate 7 circular telegram in first clean room 31 produces the electric field, in the in-process that high-voltage discharge produced plasma, the produced chemical energy of some harmful gas molecules of enough opening in the twinkling of an eye of high-frequency discharge, make it decompose into simple substance atom or harmless molecule, and under the electric field effect, can make VOCs molecule be in the excited state, when the energy that VOCs molecule obtained is greater than the binding energy of its molecular bond ability, the chemical bond of VOCs molecule will break, directly decompose into simple substance atom or constitute by single atom and get harmless gas molecule. And then enters the second purifying chamber 32 through the vent, and the activated carbon 85 in the second purifying chamber 32 has strong adsorption effect and can further adsorb and remove the residual harmful substances in the gas. Finally, the gas enters the third purifying chamber 33 through another vent, and the gas is disinfected and sterilized by using the ultraviolet rays irradiated by the UV lamp 9, so that escaping waste gas is avoided, and the purifying effect is greatly improved. The first and second filtering plates 111 and 121, which intercept particulate impurities in the sprayed water, are installed inside the first and second washing chambers 11 and 12, respectively, so that the circulation pump 14 can send the washing water of the first and second washing chambers 11 and 12 to the first shower head 112 and the atomizer 122 again, thereby realizing the recycling of the washing water and being more economical and environmentally friendly. Inside the activated carbon adsorption mechanism 8 is packed into from the purifying box 3 top through the connected mode of draw-in groove, the connected mode flexibility, convenient to detach and installation are favorable to regularly changing activated carbon 85, set up roof 83 at casing 81 top simultaneously, and the inside on purifying box 3 top is placed to roof 83 to sealed pad 34 has been installed at their junction, can improve the leakproofness of junction from this, avoid gaseous revealing. The fixing mode of the first filter plate 111, the second filter plate 121 and the water washing tank 1 is the same as that of the activated carbon adsorption mechanism 8 and the purification tank 3, so that the first filter plate 111 and the second filter plate 121 are conveniently cleaned regularly, and the sealing property of the joint of the first filter plate 111 and the second filter plate 121 and the water washing tank 1 is also ensured.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
