Description
Technical field
The present invention relates to the chemicals of clean the boiler, a kind of energy-saving chemical additive for coal-fired boiler descaling especially is provided, belong to boiler environmental protection and energy saving technical field.
Background technology
Burnt dirt is difficult problem of coal-fired enterprise, it also is the high one of the main reasons of boiler energy consumption, its formation not only reduces furnace temperature and thermal conductivity, etching apparatus, particularly the people wears protective clothing in 180 ℃～200 ℃ stove under the temperature during blowing out snaking, can only adhere to that labour intensity was well imagined 1～2 minute.
Prior art is thought and is utilized water to meet thermal evaporation, mixes with high-temperature flue gas by catalyzer, and moment forms inflammable gas and participates in burning to increase heat energy, reduces burnt dirt generation, but its theoretical foundation deficiency does not have this possibility yet in the practical application.
At present, the additive for saving energy of in the boiler environmental technology field, using always, be divided into solid and liquid two big classes, for energy-conservation, deashing, reduction discharge of poisonous waste measurer certain effect is arranged in actual use, but can't thoroughly remove burnt dirt and prevent that burnt dirt from producing, and strengthened enterprise's production cost, it is vigorous when particularly most energy-conserving products begin, owing to can't solve the difficult problem of the coal-fired enterprise of burnt this puzzlement of dirt, last quiet nothing is lived, and makes promoting the use of of additive for saving energy be subjected to restriction widely.
Summary of the invention
The present invention discloses a kind of energy-saving chemical additive for coal-fired boiler descaling, removes the mechanism of scaling of boiler, suppresses the generation of new dirt, fundamentally solves clean the boiler, an antiscale difficult problem, reaches the purpose of energy-conservation scale removal, control discharge of poisonous waste.
And the present invention adopts catalysis, method for oxidation, decomposes intermediate product under the condition of high temperature, and combustion-supporting oxide compound, oxygen can increase substantially temperature in the stove, promote ature of coal and SO
2Deng the abundant burning of nonmetallic compound, draw up into the dirty factor and form, reduce SO
2Deng noxious gas emission; The oxide compound that decomposes, superoxide etc. are rapidly to burnt dirt surface, under the effect of high temperature, catalyzer, the physical condition and the chemical ingredients of burnt dirt are changed, become the loose shape material of porous, loose coming off under gravity and combustion gas flowing effect, have filming function simultaneously, become dirty material to fly the i.e. reaction with it in attached its surface, suppress new dirt and generate.
Additive of the present invention is made of by ratio of weight and the number of copies following composition:
KNO
3 10～15％、NaNO
3 12～17％、Na
2CO
3 20～30％、
NaC 20～35％、Fe
2O
3 6～12％、CaO 20～30％、
Resins, epoxy 0.2～0.4%, catalyzer 0.3～0.6%.
Best proportioning of the present invention is:
KNO
312 parts, NaNO
314 parts, Na
2CO
325 parts, 30 parts of NaCl,
Fe
2O
38 parts, 10 parts of CaO, 0.2 part of Resins, epoxy, 0.4 part of catalyzer.
Concrete technology of the present invention is as follows: through being crushed to 20～40 order left and right sides powder, batch mixes stirs and gets final product in proportion with above-mentioned chemical crystal or cake mass.
The scope of application of the present invention comprises: all coal-fired boilers, Civil energy-saving cooking stove, fiery pit etc.
Using method: additive is 2/10000ths ratio consumptions of bunker coal.Also can press number of times, strengthen consumption according to the fouling severity by the type of furnace.The boiler relatively poor for coal, that fouling is serious, descaling rate are 100%, and ature of coal is good, the clean the boiler DeGrain that fouling is few, but energy-conservation grade all has good result.
The present invention to the burnt dirty origin cause of formation of boiler, in conjunction with now changing scientific and technological achievement, utilizes catalysis, method for oxidation according to the principles of chemistry, and scale removal, antiscale reduce the discharging of pollutent, and be energy-saving and cost-reducing.In the present invention, KNO
3, NaNO
3Be oxygenant, NaNO
3, the mechanical property of for a change burnt dirt of NaCl Resins, epoxy and physicochemical property and add annexation; Fe
2O
3Be the incendivity when improving low temperature, improve the effect of incendiary stability; CaO looks practical situation and can strengthen or reduce consumption as additive; Cu
2Cr
2O
4As catalyzer.
Difference with the prior art of the present invention is: prior art is only energy-conservation merely, or does not have descaling function or descale effect is not good, and that the present invention has is energy-conservation, descale effect is obvious; Prior art can only make the interior temperature of stove improve 100 ℃, and temperature improves 300 ℃ in the stove and the present invention can make; Prior art be by catalysis etc. make metallic compound in the stove, nonmetallic compound participates in burning increases heat energy, and the present invention is fully burned volatile matter with the heat energy that catalysis, oxidation produce to reduce noxious gas emission and suppress new dirt generation.
Positively effect of the present invention is nontoxic for having, harmless, nonflammable, non-explosive, and using method is simple, and consumption is few, and characteristics such as instant effect can thoroughly be removed burnt dirt, and the new dirt of inhibition generates, and is energy-saving and cost-reducing, direct fractional energy savings 5.5%, and the synthesis energy saving rate is 11%; Reduce harmful gas emission, help environment protection, SO2 concentration reduces by 23.8%, and quantity discharged reduces by 40%; Dust concentration reduces by 37.2%, and quantity discharged reduces by 58%; Reduce labour intensity, prolonged the turnaround, slowed down equipment corrosion.
Fundamentally remove burnt dirt through scientific formula, suppress new dirt and generate, energy-saving and cost-reducing, control pollutant emission etc., safe and reliable.
