Abstract
A flue gas desulfurizer is prepared from the following raw materials by weight: 100-120 parts of active carbon powder, 30-34 parts of calcium hydroxide, 10-12 parts of carboxymethylcellulose sodium, 10-12 parts of fly ash, 3-4 parts of pectin, 40-45 parts of diatomite, 20-24 parts of vermiculite, 20-24 parts of radical lobelia, 30-35 parts of herba lycopi, 100-120 parts of moso bamboo, 1-2 parts of sodium dodecyl benzene sulfonate, 4-5 parts of auxiliary agents, and a proper amount of water. By using active carbon, diatomite and vermiculite, the desulfurizer of the invention has adsorption and ion exchange effects; by using calcium hydroxide and fly ash, rapid desulfurization is realized and energy is saved; by using moso bamboo and Chinese herbal medicine, the desulfurizer of the invention has antibacterial and adsorption effects; the desulfurizer of the invention has good removal capability for sulfur dioxide, is easy to regenerate, and causes no secondary pollution.
Description
Technical field
The present invention relates to a kind of desulfurizing agent, relate in particular to a kind of 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 fume desulfurizing agent and preparation method thereof, this desulfurizing agent can remove the SO in flue gas effectively
2, easily, cost is lower in regeneration.
Technical scheme of the present invention is as follows:
A fume desulfurizing agent, is characterized in that being made by the raw material of following weight portion: activated carbon powder 100-120, calcium hydroxide 30-34, sodium carboxymethylcellulose 10-12, flyash 10-12, pectin 3-4, diatomite 40-45, vermiculite 20-24, Chinese lobelia 20-24, snake king's grass 30-35, mao bamboon 100-120, neopelex 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 fume desulfurizing agent, it is characterized in that comprising the following steps: Chinese lobelia, snake king's grass, mao bamboon are pulverized, send in retort together with diatomite, vermiculite, at 680-770 ℃, 2-3 hour is processed in charing, takes out, and adds furnishing mud shape in suitable quantity of water together with sodium carboxymethylcellulose, neopelex, pectin, 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, by using active carbon and diatomite, vermiculite, has absorption and ion exchange; By using the desulfurization rapidly of calcium hydroxide and flyash, and saved the energy; By using mao bamboon and Chinese herbal medicine, there is antibacterial and suction-operated; Well the remove ability of the present invention to sulfur dioxide, regeneration is easy, and non-secondary pollution.
