Abstract
An attapulgite flue gas desulfurizer is prepared from the following raw materials by weight: 100-120 parts of attapulgite, 40-45 parts of active carbon, 20-24 parts of magnesium chloride, 4-5 parts of zinc oxide, 25-28 parts of calcium oxide, 6-8 parts of sodium carbonate. 20-24 parts of wild chrysanthemum flowers, 10-12 parts of cordate houttuynia, 35-40 parts of monazite powder, 5-7 parts of sodium metasilicate, 3-4 parts of coconut fatty acid monoethanolamide, 4-5 parts of auxiliary agents, and a proper amount of water. By using attapulgite and monazite powder, the desulfurizer of the invention has adsorption decoloration and ion exchange effects, has good adsorption effect on sulfur dioxide, decreases the using amount of active carbon, and reduces the cost; by using wild chrysanthemum flowers and cordate houttuynia, the desulfurizer of the invention not only has adsorption effect, but also has antibacterial effect after carbonization; by using a plurality of basic metal oxides, rapid desulfurization is realized; the desulfurizer of the invention is high in porosity, large in adsorption quantity, easy to regenerate, and simple in production process, and can greatly reduce the operation cost of dry-method desulfurization.
Description
Technical field
The present invention relates to a kind of denitration desulfurizing agent, relate in particular to a kind of attapulgite 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, with alkaline aqueous solution, absorbs the sulfur dioxide in flue gas, and 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.
The method that removes NO and NO2 in flue gas mainly contains two kinds of modes, the one, by NO and NO2 reduction, as utilize ammonia (NH3) as reducing agent, be reduced to nitrogen, need to be according to the operational load of boiler, constantly adjust the straying quatity of NH3 and spray into position, to guarantee spraying into NH3 under optimum temperature, this method operating cost is higher; Another kind is that its oxidation is converted to nitrate, thereby reaches the object that removes NO and NO2.
Summary of the invention
The object of the present invention is to provide a kind of attapulgite fume desulfurizing agent and preparation method thereof, this desulfurizing agent can remove the SO in flue gas rapidly
2, reusable, cost is lower.
Technical scheme of the present invention is as follows:
An attapulgite fume desulfurizing agent, is characterized in that being made by the raw material of following weight portion: attapulgite 100-120, active carbon 40-45, magnesium chloride 20-24, zinc oxide 4-5, calcium oxide 25-28, sodium carbonate 6-8, mother chrysanthemum 20-24, cordate houttuynia 10-12, monazite powder 35-40, sodium metasilicate 5-7, Coconut Fatty Acid Monoethanolamide 3-4, 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 attapulgite fume desulfurizing agent, it is characterized in that comprising the following steps: mother chrysanthemum, cordate houttuynia are pulverized, send in retort together with attapulgite, monazite powder, at 660-770 ℃, 3-4 hour is processed in charing, takes out, and adds furnishing mud shape in suitable quantity of water together with active carbon, sodium metasilicate, Coconut Fatty Acid Monoethanolamide, magnesium chloride, 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
Desulfurizing agent of the present invention, by using attapulgite, monazite powder, has adsorption bleaching, ion exchange, good to Adsorbent for Sulphuric Dioxide Adsorptive Capacity, has saved activated carbon dosage, cost; By using mother chrysanthemum, cordate houttuynia, through charing, not only there is suction-operated, also there is antibacterial action; By using the desulfurization rapidly of multiple alkaline metal oxide; Desulfurizing agent of the present invention, porosity is high, and adsorbance is large, and easily, production technology is simple, can significantly reduce dry desulfurization operating cost in regeneration.
