Abstract
An ecological environment-friendly desulfurizer is prepared from the following raw materials by weight: 50-55 parts of diatomite, 40-45 parts of charcoal, 23-27 parts of iron ore tailings, 20-24 parts of calcium oxide, 4-5 parts of potassium carbonate, 1-2 parts of lanthanum hydroxide, 12-15 parts of calcium citrate, 30-35 parts of oyster shells, 1-2 parts of sodium carbonate, 5-8 parts of brown sugar, 5-10 parts of wrinkled giant hyssop, 20-24 parts of honeysuckle flowers, 3-4 parts of laurinol polyoxyethylene ether, 4-5 parts of auxiliary agents, and a proper amount of water. By using oyster shells, diatomite, and iron ore tailings, through high temperature processing, the desulfurizer of the invention is developed in pores, high in activity, and strong in adsorptivity, reduces environment pollution, and reduces the cost; by using wrinkled giant hyssop and honeysuckle flowers to process active carbon, the desulfurizer of the invention is antibacterial; the ecological environment-friendly desulfurizer of the invention causes no secondary pollution, and is worthy of popularization and application.
Description
Technical field
The present invention relates to a kind of desulfurizing agent, relate in particular to a kind of ecological, environmental protective 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 ecological, environmental protective desulfurizing agent and preparation method thereof, this desulfurizing agent rate of sulphur expulsion is fast, ecological, environmental protective.
Technical scheme of the present invention is as follows:
An ecological, environmental protective desulfurizing agent, is characterized in that being made by the raw material of following weight portion: diatomite 50-55, charcoal 40-45, iron ore tailings 23-27, calcium oxide 20-24, potash 4-5, lanthanum hydroxide 1-2, calcium citrate 12-15, oyster shell 30-35, sodium carbonate 1-2, brown sugar 5-8, wrinkled giant hyssop 5-10, honeysuckle 20-24, ethoxylated dodecyl alcohol 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 ecological, environmental protective desulfurizing agent, it is characterized in that comprising the following steps: oyster shell, wrinkled giant hyssop, honeysuckle are pulverized, send in retort together with diatomite, iron ore tailings, at 680-770 ℃, 2-3 hour is processed in charing, takes out, and adds furnishing mud shape in suitable quantity of water together with charcoal, brown sugar, potash, lanthanum hydroxide, calcium citrate, 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 oyster shell, diatomite, iron ore tailings, and through high-temperature process, hole is flourishing, and active high, adsorptivity is strong, has reduced environmental pollution, has reduced cost; By using wrinkled giant hyssop, honeysuckle to make active carbon, can be antibacterial; The present invention is ecological environment-friendly type desulfurizing agent, does not produce secondary pollution, is worth of widely use.
