Abstract
The invention discloses a kind of liquid clean coal additive, it is made up of following component by mass percentage: cerous nitrate or holmium nitrate 0.5 2%, copper sulfate or copper nitrate 2 8%, potassium permanganate or potassium ferrate 1 5%, dodecylbenzene sodium sulfonate or polyvinylpyrrolidone 2 6%, surplus is deionized water.The liquid clean coal additive that the present invention provides, it can improve ignition temperature and the thermal efficiency, reduce boiler slag carbon content, reduce slag carbon dioxide and the discharge capacity of flue dust, and make full use of discarded coal.Save fat coal resource, thus save the consumption of coal and reduce the coal combustion pollution to environment.Additionally, liquid additive overcomes again the shortcoming that solid adds, it is only necessary to the strength spray equipment that adds on conveying coal belt feeder and spray flux are proportional with upper coal amount, and easy to operate efficiency is high, and spraying is uniform.
Description
Technical field
The present invention relates to a kind of fine chemical product, refer specifically to a kind of liquid clean coal additive.
Background technology
Coal is a kind of important energy and raw material, is the main fuel of Industrial Boiler.But traditional coal-fired mode has perhaps
Many shortcomings, as fat coal burns endless, colm cannot utilize, and pollutant emission is serious etc. on the impact of environment.In order to overcome
Above-mentioned deficiency, present way be the combustion characteristics according to this coal, caloric value, volatility and catch fire, sulphur content, slagging scorification
Property, the combustion index such as after-flame, by Coal rank according to a certain ratio, and add forming agent, sulphur-fixing agent, produce different performance, combustion
Burn completely, the less Filter Tuber For Clean Coal of pollutant emission.
But, improve burning of coal quality, the fire box temperature of raising Industrial Boiler and the thermal efficiency, minimizing the most further and give up
The discharge capacity of slag waste gas, improve the utilization rate of the discarded coal in colm even colliery, be still significant.
Summary of the invention
It is desirable to provide a kind of liquid clean coal additive, it can improve ignition temperature and the thermal efficiency, reduce stove
Slag phosphorus content, reduces slag carbon dioxide and the discharge capacity of flue dust, and makes full use of discarded coal.Save fat coal resource, from
And save the consumption of coal and reduce the coal combustion pollution to environment.Additionally, liquid additive overcomes again the shortcoming that solid adds,
Have only to conveying coal belt feeder on add one strength spray equipment and spray flux proportional with upper coal amount, easy to operate
Efficiency is high, and spraying is uniformly.
A kind of liquid clean coal additives technology scheme of the present invention is: liquid clean coal additive, by by percent mass
The following component composition of ratio: cerous nitrate or holmium nitrate 0.5-2%, copper sulfate or copper nitrate 2-8%, potassium permanganate or potassium ferrate
1-5%, dodecylbenzene sodium sulfonate or polyvinylpyrrolidone 2-6%, surplus is deionized water.
Preferably, a kind of liquid clean coal additive, it is made up of following component by mass percentage: cerous nitrate 0.5%,
Copper sulfate 7%, potassium ferrate 5%, dodecylbenzene sodium sulfonate 2%, deionized water surplus.
Preferably, a kind of liquid clean coal additive, it is made up of following component by mass percentage: holmium nitrate 0.5%,
Potassium ferrate 3%, copper sulfate 7%, polyvinylpyrrolidone 2%, deionized water surplus.
Preferably, a kind of liquid clean coal additive, liquid section coal sulfur-fixing agent in use with the mixing ratio of coal
Example is 1:2000-4000 in mass ratio.
Preferably, a kind of liquid clean coal additive, liquid section coal sulfur-fixing agent in use with the mixing ratio of coal
Example is 1:2000 in mass ratio.
The invention have the benefit that this liquid clean coal additive large-sized boiler power plant, cement plant use on grasp
Facilitating, spraying is uniformly.In described copper sulfate or the copper ion of copper nitrate is in complexation steady statue and plays catalytic action, holmium nitrate
Or cerous nitrate can reduce burning of coal activation energy, play promoting catalysis.The Main Ingredients and Appearance playing degradation agent effect is ferric acid
Potassium or potassium permanganate.Play predominantly cationic surfactant, the nonionic surfactant such as polyethylene of dispersant effect
Ketopyrrolidine or dodecylbenzene sodium sulfonate.This liquid clean coal additive not only makes coal fully burn, and can the solid sulfur of environmental protection.
Sulfur-fixing rate is also high than prior art.Through on probation, the present invention reduces burning of coal activation energy, to saving coals from boiler more than 5%,
Gu sulfur reaches 40-60%.
