Description
Technical field
It is helped the present invention relates to a kind of nano-catalytic desulfurization and dislikes ENERGY-SAVING AGENT FOR and its manufacturing method.
Background technique
It is current in industry, civil boiler walk slowly like a woman coal desulphurization energy-saving technology greatly mostly use addition chemicals or physical means come
Realize combustion-supporting, desulfurization purpose, but equal existing defects: desulfurization degree is low, generally below 45%;By-product utilization rate is low, thus
Some difficulties are faced in popularization.
Nanotechnology increasingly has been favored by people as one of technology the most advanced in the world today, application,
Using the technology, some compounds can be made to generate specific performance under state of receiving, to be industrial production, domestic life service.
Summary of the invention
The object of the present invention is to provide a kind of nano-catalytic desulfurization to help walk slowly like a woman ENERGY-SAVING AGENT FOR and its manufacturing method, uses advanced
Nanotechnology realizes the combustion-supporting purpose of coal desulfurization using specific performance caused by the compound under nm regime.
To achieve the above object, the present invention takes following design scheme: this nano-catalytic desulfurzing energy saving combustion improver contains
Nanocatalyst, promotor, sulphur-fixing agent, help the burnt agent of tender solution, and the weight percent of each component is nanocatalyst 0.3-10%, promotees
Into agent 5-10%, sulphur-fixing agent 50-70%, the burnt agent 25-30% of combustion-supporting solution.
The manufacturing method of this nano-catalytic desulfurzing energy saving combustion improver is as follows:
1) it stocks up respectively by the heavy percentage of each component;
2) the burnt agent of promotor, sulphur-fixing agent and combustion-supporting solution crushed respectively at normal temperature, ground, collected;
3) it is uniformly mixed at normal temperature with nanocatalyst;
4) finished product packing.
The nanocatalyst is that the calcium chloride of nano-scale particle size and nanoscale ferrous acid brill mix, and calcium chloride and is received
It is respectively 75% that meter level carbonic acid, which bores weight percent, 25 %.
The promotor is calcium chloride
The sulphur-fixing agent is calcium oxide and carbonic acid with mixing, and weight percent is respectively that calcium oxide 90%, carbonic acid are same
10%。
The combustion-supporting solution coke agent is atmosphere sodium and atmosphere calcium, and weight percent is sodium chloride 60%, calcium chloride 40%.
The invention has the advantages that product can promote more by force the tender burning of coal to generate, boiler thermal efficiency is improved, is sloughed in flue gas
The flyash that the tender coal that sulfur dioxide, nitrogen oxides add this product generates after walking slowly like a woman can be used as the filler of cement;And it can extend
It walks slowly like a woman service life of coal burning boiler, reduces dust discharge capacity.
Specific embodiment
Embodiment 1: being used for sulphur coal, stocks up in following component ratios
Nano-scale particle size calcium chloride 0.3kg
Nanoscale metatitanic acid bores 0.1kg
Calcirm-fluoride 5kg
Calcium oxide 68kg
Barium carbonate 6kg
Sodium chloride 17kg
Calcium chloride 9kg
Calcirm-fluoride, calcium oxide, barium carbonate, sodium chloride, calcium chloride are crushed respectively at normal temperature, are ground to 300 mesh, is collected, it is standby
With.It will bore as the nano-scale particle size calcium chloride of nanocatalyst, nanoscale metatitanic acid and mixed in the ratio again, then under room temperature
Mix homogenously;Finished product packing.
In use, so that desulfurization degree reaches 70%-80%, flyash makees cement filler utilization due to the effect of nanocatalyst
Rate is up to 100%0
Embodiment 2: it for high calcium coal more inferior, stocks up in following component ratios
Nano-scale particle size atmosphere calcium 28kg
Acid bores 9kg to nanoscale by the emperor himself
Calcirm-fluoride 8kg
Calcium oxide 54kg
Barium carbonate 6kg
Atmosphere sodium 12kg
Grabbing calcium 8kg
Making step is the same as described in embodiment 1
In use, making sulphur and the abundant chemical combination of calcium oxide in colm, so that desulfurization degree reaches due to the effect of nanocatalyst
70%-85%, flyash can be used as the substitute of clinker, and utilization rate is up to 100%.
Nanocatalyst in the various embodiments described above in formula is the grabbing calcium of nano-scale particle size and admiring for nano-scale particle size
Acid is bored and is mixed, and the grabbing calcium of this two kinds of nano-scale particle sizes and the acid brill of admiring of nano-scale particle size can directly select the Chinese Academy of Sciences
The product that Shanghai silicate research institute or Changchun east nanosecond science and technology company produce.
In order to reduce cost, calcium oxide can also be substituted by part calcium hydroxide, calcium carbonate, and substitution ratio is no more than oxygen
Change 40 inner %. of calcium
Present invention nano-catalytic desulfurization produced helps the energy saving river (NHS) of suspicion, has stronger desulfurization, combustion-supporting, energy saving and waste
The effect utilized.The NHS developed with the present invention can be reduced with being added in fire coal on a small quantity while saving coal consumption
The major pollutants such as the sulfur dioxide, flue dust and the nitrogen oxides that discharge in coal-fired air, coal walks slowly like a woman the waste after burning again can be with
Partial filler as cement accomplishes waste utilization.This has significant social benefit to the improvement of China's air pollution due to coal combustion
And economic benefit.
Basic principle of the invention is: NHS is mainly added by industrial chemicals such as nanocatalyst, sulphur-fixing agent, the burnt agent of combustion-supporting solution
Work forms, to dislike based on coal, scientifically according to the low, medium and high temperature of tender coal process relatively needed for different role catalyst,
Promotor helps the burnt agent of tender solution to accelerate burning of coal to reduce the tender point of coal, promotes burner hearth lip temperature, fills the tender burning of coal quality
Point, reduce phosphorus content and suspended particulate in coal ash.Sulphur-fixing agent can promote carbon monoxide and sulfur dioxide generation heat release in coal anti-
It answers, and since there is special stability at 1300 DEG C or more by other basic anhydride such as diatomic base barium metal etc. in reaction,
To play sulfur fixation, higher desulfurization degree ensure that.
It is reacted are as follows: BaO+SO3=BaSO4
The present invention application method produced for helping agent of walking slowly like a woman is, can by NHS directly with the artificial mix homogenously of the coal that walks slowly like a woman, its ratio be
The NHs of 50kg is mixed in 1000Kg coal.If considering the utilization of byproduct, it can be mixed in coal according to different coals quality and bigger ratio is added
Example, places 10% NHS, and ball milling, which is mixed well, can be used, suitable for the cyclone furnace of various right coals, coal-powder boiler, fluidized bed furnace, heat supply stove,
Close furnace etc..
It is of the invention easy, practical, it is proved according to Experimental comparison, dislike burning value, full combustion due to improving, can economize on coal 8-15%,
Especially high calcium coal effect inferior is become apparent from;Due to solid sulphur desulfurization effect outstanding, desulfurization degree can be made 60% or more, part
Sulphur coal is up to 75% or more, and for low-sulfur coal burning boiler, its alternative desulfurizer, reaching reduces cost, the purpose improved benefit.
The present invention is a comprehensive utilization of waste materials technology again, and the lime-ash of coal-fired output, being crushed modification can be used as cement
The filler of production, the addition of high quality filler is up to 50% or more.This increases economic efficiency for reducing production cost, improves ecology
Environment promotes environmental protection, is of great significance.
