Abstract
The invention relates to a furnace calcification desulphurization mineral powder material, comprising the following components in percentage by weight: 10-40 parts of alkaline tuff, 5-10 parts of bluestone, 10-25 parts of horse tartar, 15-35 parts of limestone and 10-30 parts of silica. Crushed alkaline tuff, bluestone, horse tartar, limestone and silica are weighed and prepared according above weight percentages. All the raw materials are crushed and dried, the mixture is ground into 50-150 meshes in a ball grinding mill, and no particulate mineral material less than 50 meshes exist, and thus the product is obtained. The alkaline tuff is utilized, and based on adsorbability, hydroscopicity and expansibility of the alkaline tuff, contact area with SO2 gas and adsorption capacity to SO2 gas in a desulphurizing process are improved, and desulphurization degree can reach 97%.
Description
Technical field
The present invention relates to a kind of product for sulphur removal in industrial combustion furnace, specifically calcification desulfurization mineral powders in stove.
Background technology
In industrial combustion furnace, there is a large amount of SO
2gas, the emission standards for sulfur dioxide of national regulation is 900mg/m3, without the combustion exhaust of desulfurization, can not discharge.Therefore, sweetening effectiveness is to be related to the key that can Yi Ge enterprise combustion exhaust discharge.Desulfurization technology is widely used at circular fluid bed and low sulphur coal user at present, in stove, spray into sweetening agent (Wingdale, rhombspar, slaked lime or sodium bicarbonate etc.), in cigarette temperature, be 900～1250 ℃ of regions, sweetening agent is decomposed into CaO or MgO, then generates calcium sulfate and reach desulfurization object with SO2 effect.In addition, the purity of Wingdale, water ratio are all relevant with desulfuration efficiency.In addition, the pore-forming performance after lime burning also has a significant impact desulfurization.In Paleogene system Cai Jia punching group-and alkaline tuff, it is containing zeolite 58%, montmorillonite 1068%, ω (K2O)=3.71%, total amount of rare earth ω (REO)=0.034%.Tool adsorptivity, water-absorbent, swelling property and cation exchange property, be mainly used in improveing soil in agriculture production at present, and the composite fertilizer containing rare earth element is provided, and for industrially desulfurized report, also do not have.
Summary of the invention
Object of the present invention be exactly disclose a kind of by improving calcification desulfurization mineral powders in the stove of the pore-forming performance after lime burning.To make up the problem that current raw material calcium content purity is not high, to obtain higher desulfurization, imitate.
The technical scheme that realizes above-mentioned purpose is:
Calcification desulfurization mineral powders in stove, its composition comprises alkaline tuff, green stone, gingival cyst of mucous gland in the newborn stone, Wingdale, silica; Percentage meter by weight, its neutral and alkali tuff 10-40, green stone 5-10, gingival cyst of mucous gland in the newborn stone 10-25, Wingdale 15-35, silica 10-30.

In described raw material: green stone calcic is not less than 58%, gingival cyst of mucous gland in the newborn stone calcic is not less than 62%, Wingdale calcic is not less than 55%, silica calcic is not less than 41%.
Taken amount batching within the scope of the weight percent value that alkaline tuff through broken, green stone, gingival cyst of mucous gland in the newborn stone, Wingdale, silica are provided in scheme.All raw materials are levigate to 50-150 order by product in fragmentation, oven dry, ball mill, can not have lower than 50 object particulate mineral powder body materials, obtain product.
As produce 1 ton of desulfurization mineral powders of the present invention, in constituent, the consumption of each composition can be: 235 kilograms of alkaline tuffs, 100 kilograms of green stones, 215 kilograms, gingival cyst of mucous gland in the newborn stone, 340 kilograms, Wingdale, 110 kilograms, silica; Treated processing makes 1 ton of product.
S in fuel produces SO in combustion processes
2, the CaO producing with stove sodalime stone flour decomposes reacts and generates CaSO
3, CaSO
3through oxidation, generate CaSO
4, CaSO
4or CaSO
3with lime-ash, get rid of, thereby realized desulfuration in furnace in combustion processes.
Positively effect of the present invention is: owing to having used the alkaline tuff of 10-40% in the material being mixed into, utilize its adsorptivity, water-absorbent, swelling property etc., improve in sweetening process contact area and adsorptive power with SO2 gas, made the CaO and the SO that in material, by green stone, gingival cyst of mucous gland in the newborn stone, Wingdale, silica, are supplied with
2gas has sufficient time and space that chemical reaction occurs, and generates CaSO
4or CaSO
3with lime-ash, get rid of.The emission standards for sulfur dioxide of national regulation is 900mg/m
3, using calcification desulfurization mineral powders in the technology of the present invention stove, desulfurization degree can reach 97%, and sulfur dioxide emissioning concentration is 300mg/m
3.Sulfur dioxide emissioning concentration when not using other sweetening agent is 4000mg/m
3.Use this product can save raw coal 10%, the waste residue producing is not lumpd, the waste residue of generation can be used for producing cement.Make industrial enterprise produce realize the effect of clean, energy-conservation, consumption reduction, environmental protection.
