According to device described in the utility model, wherein, the sealed bottom of the pallet 3 is simultaneously provided with air outlet, described Air outlet connecting fan 9.
When utilizing sintering processes coking chemical waste water using device described in the utility model, comprise the following steps:
1) sinter mixture is placed on pallet, sinter mixture is burnt after igniting, and mix the sintering of burning Close material layering;
2) when the sinter mixture of burning separates burning zone and burning zone moves to sinter bed sintering end point, utilize Coking chemical waste water atomizer is atomized coking chemical waste water and sprays it, coking chemical waste water aerosol mixtures is carried out into sintering deposit finished layer Reaction, the coking chemical waste water containing toxic organic compound forms non-toxic gas and enters sintering flue gas, most heel row through Pintsch process, oxidizing fire Go out.
During above-mentioned utilization sintering processes coking chemical waste water, wherein preferably, the straying quatity of the coking chemical waste water is 1-3kg/t burnings Knot compound.
By rationally control straying quatity, prevent straying quatity big, cause cooling sintering deposit finished product too fast, efflorescence sintering deposit into Product.
During above-mentioned utilization sintering processes coking chemical waste water, wherein, same to said apparatus, the coking chemical waste water atomizer also includes point Firearm and distributing device, the distributing device are placed at the pan feeding of pallet top, for arranging sinter mixture on pallet, The igniter is placed in after pallet top, distributing device, for lighting sinter mixture.
During above-mentioned utilization sintering processes coking chemical waste water, wherein, same to said apparatus, the pallet sealed bottom is simultaneously provided with Air outlet, the air outlet connecting fan makes sinter mixture layering after burning on pallet, also, suction coking chemical waste water Aerosol mixtures enter burning zone.
The utility model has the advantage of, on the basis of existing sintering circuit, increase coking chemical waste water atomizer, using sintering Ore deposit high temperature is cracked and oxidizing fire to toxic organic compound in coking chemical waste water, and generation non-toxic gas enters sintering flue gas.Solve Iron and steel enterprise's coking chemical waste water pollution environment and the high cost brought using biochemical treatment and the problem for the treatment of effeciency difference.
