Description
Technical field:
The present invention relates to a kind of novel high-efficiency environment friendly combustion-supporting coal-saving agent that is applicable to coal fuel and preparation method thereof.
Background technology:
21 century, coal fuel development strategy emphasis was that development has safe and reliable, energy-saving and environmental protection, high stability and high-performance coal fuel cheaply.
Along with closing on of Olympic Games step in 2008, the energy-saving and emission-reduction task seems urgent more to be badly in need of, and sustainable development already also is a stern challenge for Chinese coal.For the coal fuel market, greatly develop clean energy-saving fuel, can't but go ahead, and, seize the key of deciding the issue of the battle that " green " commanding elevation will become the next round market competition for coal fuel production enterprise.As everyone knows, the coal energy consumption is the major cause that causes environmental pollution and global greenhouse gas emission.In recent years, energy consumption and the climate warming problem brought of consumption of coal explosive growth can not be ignored.
The heat energy utilization rate of coal in China differs greatly compared with developed countries, and energy growing tension and environmental pollution are one of main crises of facing of China, also is the principal element of restriction Economic development and social safety, and environment protection has been put into China's fundamental state policy.China is world big coal country, it also is world consumption coal big country, about 2,200,000,000 tons of the whole nation annual consumption coal, account for more than 75% of whole energy consumption, developed country's coal resources utilization ratio is 60-80%, and China is about 28%, and a large amount of energy is discharged from chimney and lime-ash, this not only causes the energy to waste greatly, has also caused the serious environmental pollution.In the last few years; China has put into effect " economizing energy law ", " Law on Environmental Protection ", the Air Pollution Prevention Law, Water Pollution Prevention Law, " prevention and control of environmental pollution by solid wastes method " etc. in succession; progressively limit scatter fire of raw coal since big and medium-sized cities in 2000; actively carry out using clean energy; the exploitation and the use of restriction high-sulfur, ash-rich coal, the pollution of emphasis control acid rain and sulfurous gas.
In the past few years, there are many provinces and cities and units concerned to begin to take measures, strive and save energy can prevent air environmental pollution again, become the major subjects of research from fire coal.
The ignition dope of domestic development has liquid and solid-state two kinds.Ton coal add-on does not wait from 0.05-3kg, the ton coal increase cost surplus ten yuan surplus 30 yuan, coal saving rate 5-30%.From composition, most ignition dopes all have CaCl, CaNO
3, NKO
3Deng obnoxious flavour, boiler plant is caused corrosion.And existing additive for fire coal is all failed to improve on technical formula and is solved the coal-fired performance of using, and the emission reduction effect of economizing on coal is not obvious, and the coal and the boiler that are fit to have certain limitation, does not possess big area and promotes condition.
Summary of the invention:
The purpose of this invention is to provide a kind of novel high-efficiency environment friendly combustion-supporting coal-saving agent and preparation method thereof, can improve the fired coal combustion effect, safe and reliable and cost performance is high.
Above-mentioned purpose realizes by following technical scheme:
Novel high-efficiency environment friendly combustion-supporting coal-saving agent, its composition comprises: flyash, calcium oxide, potassium permanganate, brocide-water, formic acid manganese-water, SODIUMNITRATE, ferric oxide, Potcrate, sodium chlorate, isopropylcarbinol, meson oil, water, its ratio of weight and number are 7.3 parts in flyash, 0.3 part in calcium oxide, 0.4 part in potassium permanganate, concentration is 0.1 part in brocide-water of 6%, concentration is 0.2 part in formic acid manganese-water of 5%, 0.5 part of SODIUMNITRATE, 0.2 part of ferric oxide, 0.5 part in Potcrate, 0.5 part of sodium chlorate, 0.5 part of isopropylcarbinol, 0.8 part of meson oil, water 18-24 part.
The preparation method of novel high-efficiency environment friendly combustion-supporting coal-saving agent adds reactor A by said ratio with flyash, calcium oxide, ferric oxide, adds the stirring of water 6-8 part, and after all merging, static half an hour, device is squeezed into reactor D with pump after filtration; Again sodium chlorate, potassium permanganate, brocide-water, formic acid manganese-water, SODIUMNITRATE, Potcrate are placed reactor B, be warming up to 60-70 ℃ after adding water 6-8 part, begin to stir, react after 2 hours, squeeze into reactor D by pump; Again isopropylcarbinol, meson oil are placed reactor C, be warming up to 50-60 ℃ after adding water 6-8 part, begin to stir, react after 1 hour, squeeze into reactor D by pump; Mixed solution among the reactor D is stirred, after 1 hour, promptly exportable.
Beneficial effect of the present invention:
1. the present invention is liquid, it can be sprayed on the raw coal or with it equably and make " clean coal ", " moulded coal ", do not contain any composition that environment is caused secondary pollution in the technical formula of the present invention, boiler there is not any corrosive nature, and can make coal fully burn, improve boiler thermal output, energy-conservation obvious, reduce flue dust, SO in a large number
2, NO
X, discharge of harmful gases amount such as 3-4 benzopyrene, for the development of coal clean fuel provides wide space, and filled up domestic blank.To promoting human health and efficent use of resources to have realistic meaning.
2. the present invention is applicable to the coal-saving agent and the making method of many coals, many type of furnaces combustion system, and is more obvious to the low grade coal effect of coal saving, is fit to the application of various coal firing boilers and civil boiler.Can adjust raw material ratio according to the intrinsic index of different coals, improve the fired coal combustion effect, reach the effects of energy saving and emission reduction maximization.
3. the novel high-efficiency environment friendly combustion-supporting coal-saving agent of the present invention's production has good physicochemical property, and sufficient combustion can make the carbon content in the cinder reduce more than 30%, and cost is low, and remarkable in economical benefits is economized on coal more than 30%.Reduce quantity dischargeds such as carbon monoxide, sulfurous gas more than 50%.And nontoxic, harmless, non-secondary pollution; Boiler there is not any corrosion, the no incrustation on the stove inner tubal wall, nonflammable, non-explosive, safe and reliable and cost performance is high.
4. the present invention utilizes unique prescription, and adopt new technology, and utilize the part waste, the burning quick combustion, the heat height can make furnace temperature improve more than 150 ℃; Environment protecting is good, and sulphur content and lingemann blackness in the smog are less than below 1 grade, meets discharging standards; Processing method is simple, and is easy to operate, do not need main equipment.
