Specific embodiment
Below with reference to embodiment the present invention is described in detail.
Embodiment 1
It takes that 90 parts by weight sawdust micro mists, 10 parts by weight rapes are withered and 0.3 parts by weight washing powder is uniformly mixed, be ground into 200
Catalyst is made in mesh micro mist.Washing powder uses commercially available washing powder.
By coking desulfurization waste liquor, sulphur foams mix at sulfosalt mixed liquor, which is obtained by filtration sulphur slurry, incited somebody to action
The filtrate salt water obtained after filter is concentrated by evaporation to obtain salt slurries, sulphur slurries and salt slurries is mixed to get sulphur pulp waste, sulphur slurry is useless
The mass concentration of liquid is 50%.
Catalyst made from the present embodiment is added in sulphur pulp waste, additional amount is the 0.3% of sulphur pulp waste quality, it
Sulphur pulp waste is dried afterwards, the dry dry powder obtained burn and produced for subsequent sulphuric acid.Sulphur is starched after catalyst is added
The state of waste liquid, the dry state for obtaining dry powder and burning situation are shown in Table 1.
Embodiment 2-18
The catalyst of embodiment 2-18 preparation is identical as the preparation method of embodiment 1, the difference is that the group of catalyst
Divide difference, see Table 1 for details.
Table 1
The mass concentration of 1. sulphur pulp waste of note is 50%.
2. catalyst loading is the 0.3% of sulphur pulp waste quality.
3. viscosimetric analysis temperature is 60 DEG C.
By table 1 it is found that sulphur pulp waste is provided with good after catalyst produced by the present invention is added in sulphur pulp waste
Mobility eliminates the bubble in sulphur pulp waste, reduces the viscosity of sulphur pulp waste, and sulphur pulp waste is made to have good flowing
Property, after which is dried, obtained dry powder is loose prevented from caking, and storage 180 days are still existing there is no agglomerating
As, the yield of dry powder can achieve 1.5 ton/hours substantially, the dry powder obtained after drying is sent into subsequent Sulphuric acid production,
It can sufficiently burn, improve the yield for preparing sulfuric acid.
Embodiment 19-21
In embodiment 19-21, catalyst is made using embodiment 1, is added in sulphur pulp waste, not with embodiment 1
It is that the catalyst ratio that sulphur pulp waste is added is different with place, see Table 2 for details.
Comparative example 1
Directly the sulphur pulp waste that mass concentration is 50% is dried, the dry dry powder obtained burn for subsequent
Gas washing in SA production.The state of sulphur pulp waste, the dry state for obtaining dry powder and burning situation are shown in Table 2.
Table 2
Note: the mass concentration of 1. sulphur pulp wastes is 50%；
2. viscosimetric analysis temperature is 60 DEG C.
By table 2 it is found that in comparative example 1, catalyst of the invention is not added, the viscosity of sulphur pulp waste is at this time
2.491, mobility is very poor, in embodiment 19, is simply added into 0.1% catalyst, so that it may reduce the viscosity of sulphur pulp waste
To 1.982, in embodiment 21,5% catalyst is added, the viscosity of sulphur pulp waste can be reduced to 1.712, it is seen then that is added
Catalyst of the invention significantly reduces the viscosity of sulphur pulp waste, improves mobility.In comparative example 1 by sulphur pulp waste directly into
Row drying, obtained dry powder are easy agglomeration, caking phenomenon just occur within storage 7 days, are only capable of 1 ton of dry powder of production per hour, and in sulphur
After catalyst of the invention is added in pulp waste, the dry powder being dried to obtain can store 180 days without caking phenomenon, and
Yield can achieve 1.5 tons or so, than the output increased 50% or so of comparative example 1.In subsequent preparation gas washing in SA production, comparison
The dry powder being dried to obtain in example 1 is unable to full combustion, and dries the dry powder energy that sulphur pulp waste obtains after catalyst of the present invention is added
Enough full combustions, improve the yield for preparing sulfuric acid.
