2and H
2the simple materials such as O, realize the object removing peculiar smell, in addition, NO is oxidized to NO by the active group of these higher-energy
xetc. high-valence state nitrogen, realize denitration.
3) last waste gas carries out deep purifying and the deozonize that goes out through catalytic oxidation bed, the special filler being loaded with catalyst of this catalytic oxidation bed inside filling, filler has adsorptivity, first ozone, hydroxyl radical free radical, molecular fragment etc. are adsorbed in filling surface and internal pore structure, filler under the catalyst action be loaded with continue reaction, and contaminant molecule fragment is degraded to CO further
2, H
2o etc. are pollution-free material, the oxidability that the setting of catalytic oxidation bed had both taken full advantage of ozone isoreactivity material carrys out pollution degradation material, consumes again residual ozone;
4) final, purify waste gas up to standard via the original smoke stack emission in the funeral parlor.
Advantage of the present invention and beneficial effect are:
What the present invention is directed to the cremator generation of funeral place picks up grey waste gas, effectively processes the harmful substances such as dust, VOC, gas with foreign flavor and nitrogen oxide wherein, prevents direct exhaust emission air;
