Description
Technical field
The present invention relates to a kind of desulfurizing agent, relate in particular to a kind of oxidized form fume desulfurizing agent and preparation method thereof.
Background technology
Fume desulfurizing agent mainly contains three kinds of modes at present: the one, and combustion desulfurization method, is in coal, to add a certain amount of sulphur-fixing agent, and the sulfur dioxide that coal is generated when burning reacts with sulphur-fixing agent, generates sulfate and discharges together with slag, and this method cost is higher.Another kind method is wet desulphurization, mainly adopts spray process, and with the sulfur dioxide in alkaline aqueous solution absorption flue gas, this method water consumption is large, and desulfurization afterproduct is difficult, easily produces secondary pollution, and cost of investment is high, and floor space is large, and equipment anticorrosion requires high.Also having a kind of method is active carbon adsorption, and the life cycle of the method active carbon is shorter, and regeneration is comparatively complicated, and desulfuration efficiency is low, and washing water consumption is large, easily causes secondary pollution, and active carbon price is higher, has increased cost.
In flue gas, remove NO and NO
2method mainly contain two kinds of modes, the one, by NO and NO
2reduction, as utilize ammonia (NH
3) as reducing agent, be reduced to nitrogen, need to, according to the operational load of boiler, constantly adjust NH
3straying quatity and spray into position, to guarantee spraying into NH under optimum temperature
3, this method operating cost is higher; Another kind is that its oxidation is converted to nitrate, thereby reach, removes NO and NO
2object.
Summary of the invention
The object of the present invention is to provide a kind of oxidized form fume desulfurizing agent and preparation method thereof, this desulfurizing agent can remove SO in flue gas effectively
2, desorption efficiency is large.
Technical scheme of the present invention is as follows:
A kind of oxidized form fume desulfurizing agent, is characterized in that being made by the raw material of following weight portion: bamboo charcoal 100-110, calcium oxide 20-24, magnesia 30-34, zinc oxide 10-12, polyvinylpyrrolidone 10-12, nickel oxide 30-35, cupric oxide 20-23, carboxymethyl cellulose 5-6, paris polyphylla 20-23, sodium peroxide powder 3-4, grapevine 24-28, yellow cinnamon leaf 10-12, sodium laurate 1-2, auxiliary agent 4-5, water are appropriate; Described auxiliary agent is made by the raw material of following weight portion: montmorillonite powder 10-12, titanium dioxide 1-2, jade powder 12-14, zinc gluconate 1-2, magnesia 3-4, flour 3-4, water are appropriate; Its preparation method is that flour is added to the water, and pasty state is stirred in heating, then adds other composition, makes mud shape, then sends in calcining furnace and calcine 4-5 hour at 450-500 ℃, cooling after, be ground into 100-150 order powder, obtain.
The preparation method of described oxidized form fume desulfurizing agent, it is characterized in that comprising the following steps: paris polyphylla, grapevine, yellow cinnamon leaf are pulverized, send into together in retort, at 680-770 ℃, 2-3 hour is processed in charing, takes out, and adds furnishing mud shape in suitable quantity of water together with bamboo charcoal, polyvinylpyrrolidone, carboxymethyl cellulose, sodium laurate, be heated to 80-90 ℃, grind to form 200-300 order slurry, it is neutral regulating pH value, dries; Mix and be uniformly dispersed and get final product with other surplus stocks.
Beneficial effect of the present invention
The present invention uses the plants such as paris polyphylla, through high temperature carbonization, has formed pore structure prosperity, form that specific area is large, has suction-operated, and environment protection health; By using bamboo charcoal, there is the functions such as excellent absorption, deodorizing; By using the desulfurization rapidly of multiple alkaline metal oxide; By using sodium peroxide powder, can oxidation removal SO
2, can be for removing and the SO reclaiming in the gases such as boiler of power plant flue gas, sulfuric acid industry tail gas, metallurgy sintering smoke
2, and removal efficiency is high, infiltration rate is fast, desorption efficiency is large, regeneration is easy.
