Abstract
A gas desulfurizer is prepared from the following raw materials by weight: 100-120 parts of bamboo charcoal, 30-34 parts of sodium phosphate, 3-4 parts of sodium dodecyl benzene sulfonate, 12-14 parts of sodium montmorillonite, 3-4 parts of aluminum sulfate, 8-10 parts of sodium metasilicate, 28-40 parts of edible mushroom culture materials, 20-24 parts of dandelions, 10-12 parts of chrysanthemum, 3-4 parts of sodium dodecyl sulfate, 4-5 parts of auxiliary agents, and a proper amount of water. By using edible mushroom culture materials, dandelions and chrysanthemum to process active carbon, the desulfurizer of the invention not only can adsorb sulfur, carbon, black smoke and the like, but also is environment-friendly, energy-saving, and antibacterial; by using sodium montmorillonite, the desulfurizer of the invention is good in adsorptivity, good in caking property, and good in catalysis, and saves active carbon; by using sodium phosphate and sodium metasilicate, the desulfurizer of the invention can realize rapid desulfurization; The desulfurizer of the invention is suitable for desulfurization and decarburization of natural gas, flue gas and the like.
Description
Technical field
The present invention relates to a kind of desulfurizing agent, relate in particular to a kind of gas sweetening 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.
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 gas sweetening agent and preparation method thereof, this desulfurizing agent is renewable, desulfurization is thorough fast.
Technical scheme of the present invention is as follows:
A kind of gas sweetening agent, is characterized in that being made by the raw material of following weight portion: bamboo charcoal 100-120, sodium phosphate 30-34, neopelex 3-4, na-montmorillonite 12-14, aluminum sulfate 3-4, flower bulb alkali 8-10, culture medium of edible fungus 28-40, dandelion 20-24, chrysanthemum 10-12, lauryl sodium sulfate 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, active carbon 3-4, medical stone 2-3, ammonium chloride 3-4, flour 4-5, 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 gas sweetening agent, it is characterized in that comprising the following steps: na-montmorillonite, culture medium of edible fungus, dandelion, chrysanthemum are pulverized, send into together in retort, at 700-760 ℃, 2-3 hour is processed in charing, takes out, and adds furnishing mud shape in suitable quantity of water together with bamboo charcoal, sodium phosphate, neopelex, aluminum sulfate, flower bulb alkali, lauryl sodium sulfate, 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 culture medium of edible fungus, dandelion, chrysanthemum to make active carbon, can not only adsorb sulphur, carbon, black smoke etc., and environmental protection and energy saving, can also be antibacterial; By using na-montmorillonite, excellent adsorption, caking property is good, and catalytic is good, saves active carbon; By using sodium phosphate, flower bulb alkali, can desulfurization rapidly; Desulfurizing agent of the present invention is applicable to the desulfurization and decarburizations such as natural gas, flue gas.
