Description

A kind of preparation method of ultra-fine sodium acid carbonate gas cleaning medicament
Technical field
The present invention relates to field of environment protection, relates generally to a kind of preparation side of ultra-fine sodium acid carbonate gas cleaning medicament Method.
Background technology
Issue within 2014 in China《Consumer waste incineration contamination control standard》The discharge standard of flue gas of refuse burning is made Go out more strict limitation, part index number reaches European EU2000/76/EC standards, it can be seen that, rationally at effective flue gas Reason technology is to ensure the necessary condition of garbage incinerating power plant promotion and implementation.
Existing MSW Incineration Plant, sludge incineration power plant, system for cleaning fume are using (semidry method+dry Method) depickling+activated carbon+bag-type dust flue gas purifying technique system when, usually using calcium hydroxide as gas cleaning medicament, High energy consumption, the corrosivity needed for serious, dry method injection of being built bridge when calcium hydroxide stores easy etching apparatus by force, reactivity is low, than Small removing HCl, the SO of surface area2Poor Deng pernicious gas effect, stabilizing fly ash agent usage amount is big and the grey quantity of slag of generation is big, later stage lime-ash The problems such as processing cost is higher.
Sodium acid carbonate (sodium bicarbonate) can be used to be used as adsorpting formulation to reach higher standard limit of smog release, but due to transport The reason for storage, sodium acid carbonate raw material are typically coarse granule (d50 values are about 200 μm).Such as to reach higher reactivity, Adsorbent must have larger specific surface area.Therefore before flue is injected, sodium acid carbonate must be crushed to certain fineness.Will Remove SO2Sodium acid carbonate fineness must reach d90<20 μm, and remove HCl and only require d90<35 μm, can if system operatio is correct To remove more than 95% SO2；HCl clearance is even up to 99%.The thick depickling effect of particle diameter be present in common sodium acid carbonate raw material Fruit is poor, and dosage is big, and easy moisture absorption caking can not use, jet performance is low, the problems such as causing line clogging not spray.
The content of the invention
For existing issue, a kind of cost of present invention offer is low, easily storage, and jet flow performance is good, and dispersiveness is high, mobility height Ultra-fine sodium acid carbonate gas cleaning medicament preparation method.
A kind of preparation method of ultra-fine sodium acid carbonate gas cleaning medicament, comprises the following steps：
(a) ultra fine is made to sodium acid carbonate using airslide disintegrating mill, obtains ultra-fine sodium acid carbonate；
(b) calcium oxide 60-90 parts, stearic acid 5-10 parts, silicone oil 1-5 parts, white carbon 5-20 parts, stearic acid are taken by mass parts Calcium 10-20 parts, are sequentially placed into homogenizer, and active calcium oxide is obtained after stirring 0.5-1h；
(c) taken by mass parts during 95 parts of the ultra-fine sodium acid carbonate of step (a) is put into 5 parts of the active calcium oxide of step (b) Fast mixer mixing 0.5-1h obtains ultra-fine sodium acid carbonate gas cleaning medicament to being well mixed.
Amount of heat is not produced in airslide disintegrating mill crushing process, is not in high temperature, to the chemical property of sodium acid carbonate Without influence；The stirring of step (c) is carried out in speed stirrer, and temperature is relatively low, and ultra-fine sodium acid carbonate heating can be avoided to occur to divide Solution is reacted, and in whipping process, active calcium oxide cladding sodium acid carbonate, is changed the physical property of sodium bicarbonate powder, is made it have High floodability and polymolecularity.
Further, the ultra-fine sodium bicarbonate particle particle diameter is d90<20μm.
Further, the step (b) is to take 70 parts of calcium oxide, 6 parts of stearic acid, 2 parts of silicone oil, white carbon 10 by mass parts Part, 12 parts of calcium stearate, it is sequentially placed into homogenizer, active calcium oxide is obtained after stirring 0.5-1h.
Further, the calcium oxide content is 95%.
Further, temperature is 70-90 DEG C during the homogenizer stirring.
Further, temperature is no more than 40 DEG C during the speed stirrer mixing.
The ultra-fine sodium acid carbonate gas cleaning medicament of the present invention is used as the adsorbent of flue gas desulfurization depickling, passes through chemisorbed The pollutants such as the acidity in flue gas are removed, while some inorganic and organic micro substances can be also removed by physical absorption.
The present invention ultra-fine sodium acid carbonate gas cleaning pharmacy work principle be：By by ultra-fine sodium acid carbonate gas cleaning Medicament is injected directly into high-temperature flue gas, and ultra-fine sodium acid carbonate gas cleaning medicament decomposes generation sodium carbonate Na at high temperature2CO3、H2O And CO2。
Sodium carbonate N caused by newa2CO3Have the reactivity of height in generation moment, can spontaneously with the acidity in flue gas Pollutant carries out following reaction：
Na2CO3+SO3=Na2SO4+CO2
Na2CO3+ 2HCl=2NaCl+H2O+CO2
Na2CO3+ 2HF=2NaF+H2O+CO2
Ultra-fine sodium acid carbonate gas cleaning agent activity is stronger with respect to calcium hydroxide, reacts more sharp with pernicious gases such as acidity It is strong, because the grain diameter of ultra-fine sodium acid carbonate gas cleaning medicament is d90<20 μm, specific surface area increase, proportion is lighter, empty The middle residence time is longer, ultra-fine sodium acid carbonate gas cleaning medicament is fully reacted with sour gas, can remove more than 95% SO2, HCl clearance is even up to 99%, reaches preferable medicament utilization benefit and gas cleaning effect, economical and effective Reduce the discharge of flue gas pollutant.
Main advantages of the present invention and beneficial effect are：
1st, with releasing CO after sour gas reaction2, flying dust is through CO2Infiltration, the dosage of stabilizing fly ash agent 50% can be reduced, So as to effectively reduce total use cost of gas cleaning medicament；
2nd, ash is effectively reduced except the dosage of acid treatment is about a quarter of calcium hydroxide adsorpting formulation dosage as dry method The yield and later stage lime-ash processing cost of slag；
3rd, there is outstanding physical property, the repellency of superelevation, without obvious water suction under open environment, do not lump；Greatly When tonnage stores, it can deposit the long period, it is only necessary to which less external force can abolish material arch formation；
