Abstract
The present invention discloses a kind of desulfurization denitrification agent and preparation method thereof, belongs to Making Use of Tailings utilization and industrial smoke Treatment process field.Desulfurization denitrification agent of the present invention includes phosphorus ore or phosphorus tailing 5% 45%, Iron-ore Slag 5% 25%, manganese mud 5% 30%, zinc ore slag 5% 35%, Copper Slag 1% 10%, red mud 5% 15%, rare-earth tailing 10% 35%, gangue 1% 10%.The preparation method of desulfurization denitrification agent is that above-mentioned solid by-product is milled to about 200 300 mesh respectively, powder after will be broken is mixed in a certain ratio, 1 3h is calcined under the conditions of 800 DEG C 1200 DEG C be fabricated to porous material using Muffle furnace, it is broken into 80 100 mesh powders again afterwards, becomes new desulfurization denitrification agent.The method of the invention technique is simple, and denitrification efficiency is high, and while industrial flue gas cleaning, slag has also obtained recycling, has significant economic benefit and environmental benefit.
Description
Technical field
The present invention relates to a kind of desulfurization denitrification agent and preparation method thereof, specifically using phosphorous chemical industry, non-ferrous metal metallurgy and adopt
Solid by-product in coal production technology is prepared into desulfurizing industrial fume denitrfying agent, belongs to Making Use of Tailings utilization and industrial smoke
Treatment process field.
Background technology
Industrial smoke is the primary pollution source of atmosphere pollution, and flue gas contains a large amount of sulfide, nitrogen oxides, to human body and life
The toxic effect of state system, while the main reason for still produce acid rain, it is big to there is investment in existing desulphurization denitration technology, running cost
The problems such as with height, pipeline is perishable, and technological process is complicated, and operation operation is numerous and diverse, research desulphurization denitration technology control China big
Gas pollution is of great significance.Especially simultaneous SO_2 and NO removal technology, is more of practical significance.
Mineral Resources in China is enriched, huge number.But in the process of China's mining development, generate and be largely difficult to
The solid waste utilized, such as：Phosphorus ore（Or phosphorus tailing）, Iron-ore Slag, manganese mud, zinc ore slag, Copper Slag, rare-earth tailing, bastard coal
Stone.These percentage of industrial solid waste that is comprehensively utilizeds are also relatively low at present, a large amount of to store up not only land occupation resource, also result in serious
Atmosphere pollution, soil pollution and water resource pollution, present environmental risks and human health.These solid waste but have mostly
Available value, is recycling resource.By it, simple processing is used in other pollution controls again, has both realized waste profit
With reduction pollution, also reduces the consumption of resource, the energy, be the important embodiment for implementing the strategy of sustainable development.
The widely used wet process of FGD of flue gas desulfurization and denitrification and selective catalytic reduction at this stage（SCR）It is combined skill
Art, i.e. SO2And NOxHandle respectively.Existing desulphurization denitration technology there are many problems, such as：The equipment of limestone-gypsum method
The problems such as investment is big, and desulphurization cost is high, and a large amount of gypsum of generation are difficult to handle；SCR technology there are catalyst investment is big, flue gas into
The problems such as dividing influences greatly, and operating cost is high, there are reaction temperature is high, reducing agent and flue gas mixability are poor, denitration for SNCR technologies
A series of problems, such as efficiency is low, ammonia escaped quantity is big.Therefore, there are fixed investment height, operation dimension for united desulphurization denitration technology
Protect the problems such as costly, operation is complicated.Using a kind of simultaneous SO_2 and NO removal agent, this technical matters is simple, and investment is less,
Realize SO2And NOXRemoving, and do not change existing industrial equipment, and operating cost is low, denitrification efficiency is high, clearly
Clean environmental protection.
The content of the invention
It is an object of the invention to provide a kind of desulfurization denitrification agent, utilizes phosphorous chemical industry, non-ferrous metal metallurgy（Iron, manganese, zinc,
Copper, aluminium, rare earth etc.）Desulfurizing industrial fume denitrfying agent is prepared into the solid by-product in coal mining production technology, desulfurization is improved and takes off
The efficiency of nitre.The desulfurization denitrification agent is prepared by following raw material, and each raw material and mass percent are：Phosphorus ore or phosphorus tailing
5%-45%, Iron-ore Slag 5%-25%, manganese mud 5%-30%, zinc ore slag 5%-35%, Copper Slag 1%-10%, red mud 5%-15%, rare earth tail
Ore deposit 10%-35%, the sum of gangue 1%-10%, the mass percent of all raw materials are 100%.
The preparation method of desulfurization denitrification agent of the present invention, it is characterised in that：By phosphorus ore or phosphorus tailing, Iron-ore Slag, manganese
Slag, zinc ore slag, Copper Slag, red mud, rare-earth tailing, gangue are milled to 200-300 mesh respectively, and all kinds of miberal powders after crushing are pressed
Certain proportion mixes, and the miberal powder after mixing calcines 1-3h under the conditions of 800 DEG C -1200 DEG C and is made for porous material, is crushed to 80
The mesh of mesh -100, you can obtain novel desulphurization denitrfying agent.
