Abstract
The invention relates to desulphurizing powder produced by using alkaline residue and a production process thereof. The desulphurizing powder is prepared by mixing the following components in part by weight: 30 to 85 parts of alkaline residue, 5 to 45 parts of light burned dolomite powder, 1 to 25 parts of fine mullite powder, 1 to 30 parts of aid A, 0.2 to 15 parts of aid B, 0.3 to 20 parts of aid C and 0.1 to 10 parts of aid D. The production process comprises the following steps of: drying the alkaline residue, mixing the alkaline residue, the light burned dolomite powder, the fine mullitepowder, the aid A, the aid B, the aid C and the aid D in a high-speed mixer for 10 to 30 minutes, uniformly mixing and packaging. The production process has the advantages that: the industrial waste alkaline residue is taken as a main raw material, so the waste is changed into a new resource, the production cost of the desulphurizing powder is reduced, and the problem that the stacked alkaline residue occupies land is solved; and the aids improve the effect of removing SO2, and the desulphurizing effect is obvious.
Description
Technical field
The present invention relates to a kind of sweetening agent, desulfurization powder and the production technique thereof of particularly producing with the industrial waste waste soda residue.
Background technology
New energy revolution will occur in 21 century in the world, the total trend of this revolution is with more flexible, more convenient, cleaner novel energy replaces the backward use-pattern of traditional energy and the general layout of the unordered discharging of obnoxious flavour, make the energy can give modern today to provide necessary power to go to realize producing and life requirement outside, can make again the requirement discharging up to specification of various obnoxious flavoures or zero release, also cleaner blue sky, the world, white clouds.
Make a general survey of the present world, because the irresponsibility of some advanced developed country, developing country's science and technology does not pass a test, and has more aggravated Greenhouse effect, acid rain is rampant, ozonosphere is destroyed invariably relevant with unordered discharge of noxious gases, the SO in take China as the example obnoxious flavour
290%, N
2, CO 70%, CO
280% all because form in the primary energy source working process, therefore improve the thermo-efficiency of primary energy source, reduce environmental pollution and become the task of top priority; China is energy expenditure big country, SO in the time of 2000
2Quantity discharged is 2,460 ten thousand tons, as benchmark, and Eleventh-Five Year Plan SO
2Reduce discharging 20%, realize this goal, shoulder heavy responsibilities.
Developing the cleanburning technology is that China solves the strategical decision that the primary energy source combustion product gases pollutes the atmosphere polluting problem that is the master, is the important technology direction that realizes economy, social sustainable development and economy, energy environment coordinated development; The core of cleanburning technology is the burning of primary energy source high cleaning, and wherein the solid sulphur of primary energy source desulfurization is the reduction of discharging SO of a suitable China's national situation
2One of technical measures.
Under such prerequisite, research Novel desulphurization pulvis, extremely strong vitality will be arranged, can use in fields such as metallurgy, generating, cement, Industrial Boilers, have popularity, advance and ubiquity, can realize at the primary energy source solid sulphur of middle adding certain proportion that is mixed, can in combustion processes, spray into again and fully absorb SO in burner hearth or the flue gas
2, and make SO in the atmosphere
2Concentration is reduced in the environmental permission scope or zero release.
Existing desulfurization technology uses the basic oxide such as CaO in a large number, causes a large amount of mining Wingdales, CO
2Discharging and the waste that produces the energy because of calcining, not only contaminate environment has also increased desulphurization cost, makes sweetening agent if adopt waste soda residue to do main raw material, can reduce desulphurization cost, and its application prospect will be very good.
The annual need of China is converted into about 5,000,000,000 tons in mark coal with primary energy source, coal wherein, coke etc. consume about 4,000,000,000 tons, by desulfurization powder (different add-ons being arranged according to coal sulphur content difference) the add-on scope 4%-8% that needs per ton, calculate by minimum 4%, consume 1.6 hundred million tons of desulfurization powders every year, China is calculated by existing production capacity, every annual meeting produces 3,000 ten thousand tons of waste soda residues, add that the quantity of accumulation stacking is very surprising year after year, can satisfy the annual demand that needs with desulfurization powder fully, can remove from simultaneously because producing large quantities of metallurgy limes and join number that several hundred million tons of Wingdales exploiting as desulfurization powder and burning Wingdale use up with ten million ton coke, can reduce discharging because of calcined limestone and enter the number of atmosphere with hundred million tons of CO
2, utilization of waste material is really accomplished by the tens billion of units of the fund that can save every year, resource recovery, energy-saving and emission-reduction, recycling economy will be brought huge society and economic benefit to the mankind.
Summary of the invention
The purpose of this invention is to provide a kind of desulfurization powder and production technique thereof of producing with waste soda residue, adopting the industrial waste waste soda residue is main raw material, makes waste become new resource, reduces the production cost of sweetening agent, and problem is taken up an area in the stacking that has solved again waste soda residue; The interpolation of auxiliary agent has strengthened SO
2The effect that removes, sweetening effectiveness is obvious.
