Abstract
The invention discloses an energy-saving and environment-friendly ash scavenger for a coal-fired boiler and belongs to the field of energy chemistry. The formula of the energy-saving and environment-friendly ash scavenger is characterized by being prepared from mineral oil, water, an emulsifier and a chemical agent, wherein the emulsifier is composed of sodium petroleum sulfonate, Tween 80 and carboxyl-containing starch, and the chemical agent is composed of borax, potassium chloride, sodium carbonate and potassium chlorate. The energy-saving and environment-friendly ash scavenger product is specially applied to the coal-fired boiler, has the efficacies of efficient decoking and deashing and enables the coal-fired boiler to run in a state of safety, energy saving and environmental protection; the product exists in a state of an emulsion in which a powdery chemical agent is suspended, and the chemical agent in the emulsion can enable coked substances and sintered ashes on the heating surface of the boiler to be crisp and fall off; a large number of water molecules in the emulsion can generate strong micro-explosion effect and stripping effect; as the product contains a large quantity of water, the production cost is far lower than that of a granular ash scavenger product in the prior art.
Description
Technical field
The invention belongs to energy chemical field, the present invention relates to a kind of dust-cleaning agent for boiler, what be specifically related to is a kind of soot cleaning of coal-fired boiler agent of energy-conserving and environment-protective.
Background technology
Tens thousand of, the existing boiler of China, the coal consumption of boiler accounts for the more than 1/3rd of national coal consumption amount, coal firing boiler is in the process of operation, the positions such as its water wall and superheater can serious dust stratification, stops up exhaust gases passes, and the thermo-efficiency of boiler is reduced, even may cause boiler water wall be heated inhomogeneous and cause the disastrous effect of booster, by the safe and economical operation of serious harm boiler, also have, increase extra energy consumption and extra noxious gas emission.
The content of invention
The object of the invention is provides one to be specifically applied in coal firing boiler for above-mentioned deficiency, can play efficient decoking deashing function, also makes the dust-cleaning agent for boiler of coal firing boiler economical operation under safety, energy-conserving and environment-protective state.
For achieving the above object, the technology used in the present invention case is a kind of coal furnace dust-cleaning agent of energy-conserving and environment-protective, the feature of its formula is: mineral oil, water, emulsifying agent, chemical agent composition, wherein, emulsifying agent is made up of petroleum sodium sulfonate, tween 80, carboxyl starch, and chemical agent is made up of borax, Repone K, sodium carbonate, Potcrate.
The weight percent of its component is:
Wherein, each weight percentages of components of composition emulsifying agent is:
Petroleum sodium sulfonate 20%---60%
Tween 80 20%---60%
Carboxyl starch 20%---60%
Wherein, each weight percentages of components of constitutional chemistry medicament is:
The present invention compared with the existing technology has the following advantages and positive effect: first, the soot cleaning of coal-fired boiler agent of prior art mixes composite forming by multiple compounds, they are all by oxygenant, catalyzer, ignition dope, inhibiter, additive etc. mix, activate granulation taking mineral compound as main chemical substance by certain processing condition and are made into, its production cost is higher, and, by daily a large amount of medications, could keep the effect of decoking deashing.Unlike the prior art, the soot cleaning of coal-fired boiler agent of a kind of energy-conserving and environment-protective of the present invention, its manufacturing process has been applied emulsifying technology, first by mineral oil, water, emulsifying agent carries out mix and blend emulsification, obtain the emulsion of yellow-white pasty state, add again the Powdered chemical agent with katalysis to continue to stir, until chemical agent disperses equably and is suspended in emulsion, the emulsification liquid obtaining is finished product of the present invention, this finished product can be packed with plastics bag, this finished product has preferably decoking deashing effect, when application, put into the emulsification liquid (plastic bag) of Coal-fired capacity ten thousand/left and right in boiler every day, emulsification liquid moment produces strong effect of micro-explosion, also moment changes into molten state to chemical agent in emulsification liquid, be sputtered in the surface of black dirt and close-burning thing and its formation low temperature azeotrope or more crisp sintered deposit, these products are under the effect of pinking, all be easy to separate from the heating surface of boiler, come off, also have a large amount of water molecules in emulsification liquid to be vaporized in the boiler of high temperature, produce stripping effect and purified nitrogen peroxide a large amount of in stove, sulfurous gas, the obnoxious flavoures such as carbon monoxide, coal firing boiler is moved under the state of energy-conserving and environment-protective, in addition, analyze from production cost: owing to containing a large amount of water in emulsification liquid of the present invention, so, its production cost is far below the prior art products forming with chemical agent mixing granulation.
