After the smoke dust and the gas are pumped into the robot body, the robot body firstly enters an upper water mist sedimentation photocatalytic chamber, after the smoke dust is settled by the water mist, smoke dust particles are dissolved in the water mist and coated with TiO at the upper end of the upper sedimentation photocatalytic chamber2The honeycomb aluminum net 201 of coating fully contacts, accomplishes the first more abundant photocatalysis, then drips from honeycomb aluminum net 201, along with rivers entering lower part degree of depth photocatalysis room, the gas of pump-in then lets in gas denitration desulphurization unit from the gas outlet of upper portion water smoke photocatalysis room.
The smoke solution entering the lower deep photocatalytic chamber is coated with TiO2The spiral diversion ladder pipe 203 of coating flows into the water storage bucket 202, and the pollutant of insufficient photocatalysis in the water storage bucket 202 can be pumped into the upper portion settlement photocatalysis room once more along with by the water pump 206 in the water storage bucket and become the water smoke, and two photocatalysis rooms of flowing through once more realize the circulation and repeated photocatalysis.
The gas introduced into the denitration and desulfurization apparatus is directly introduced into the gas reaction chamber 107, and the raw material is preparedSodium peroxide in the chamber 103 and CO in the flue gas2The gas reacts at a certain temperature to generate oxygen, the oxygen generates ozone under the irradiation of ultraviolet light to enter the gas reaction chamber to participate in the reaction of the introduced gas and urea, and harmful gas is oxidized to generate non-toxic and harmless safe gas to be discharged out of the whole system.
