Abstract
The present invention relates to a coal additive for purifying air and saving energy source and its preparation method. Said additive comprises eight chemical substances, which can greatly reduce the sulfur oxide, nitrogen oxide, CO and smoke in the discharged material from coal combustion, and can make the coal completely burn to obtain the obvious effect of purifying air, protecting environment and saving energy source. Its preparation method is simple, low in cost, and has no corrosion.
Description
The present invention relates to the purification of air and save a kind of method that the energy provided, specifically, the present invention relates to a kind of new coal companying additive and preparation method thereof.
After the fifties, along with a large amount of uses of the industrial expansion and the coal energy, the topsoil of each industrialized country is more and more serious in the world, in order to solve the topsoil that fire coal causes, cost substantial contribution in various countries' is transformed energy structure, uses so-called clean energy, on the other hand, coal is a kind of as usage quantity maximum in the energy, through want of funds with other condition restriction, can't withdraw from industry and life application in a short time, thus, produce various fire coals and fallen dirty technology.
The invention reside in and overcome in the existing air a large amount of obnoxious flavoures and cut down the consumption of energy, and provide a kind of easy to use, effect significantly, the coal companying additive that in fire coal, uses, and new preparation method.
Purpose of the present invention can reach by following measure, a kind of new coal companying additive is made up of eight kinds of chemical substances by weight percentage: potassium permanganate 25-30%, Manganse Dioxide 15-20%, Potcrate 5-8%, potassium bichromate 15-20%, salt of wormwood 5-10%, magnesium oxide 5-10%, zinc oxide 5-10%, calcium superphosphate 15-20%, its preparation method mix potassium permanganate and Manganse Dioxide 1.5 minutes, add Potcrate in order respectively, potassium bichromate, salt of wormwood, magnesium oxide, five kinds of materials of zinc oxide, whenever after adding a kind of material, mixed 1 minute, add calcium superphosphate at last, mix after 5 minutes, enter transfer roller, cone-type mixer, worm conveyor, storage tank, the electronics metering packing, sack closer, warehouse-in.
Coal companying additive is that powder solid is granular, proportion 1.5-1.9g/cm
3, granularity 50-200 order.
The present invention has following advantage compared to existing technology:
1, environmental benefit
According to the national environmental protection department statistics, the current atmospheric environment situation of China is very severe, has more and more become the harm people ' s health, the important factor of restriction economy and social development.1997,1,873 ten thousand tons of national smoke discharge amounts, 2,346 ten thousand tons of sulphur dioxide emission, the sulfurous gas daily mean of concentration in 62% the urban atmosphere surpasses national grade III Standard; Acid rain district, whole nation area accounts for area 30%, and Central China acid rain district acid rain frequency is up to more than 90%, and the whole nation reaches more than 1,100 hundred million yuan because of the loss that acid rain and sulfur dioxide pollution cause every year, and after 1998, it is serious that this situation more is tending towards.
Coal burning pollution is topmost a kind of source of pollution, because coal supply channel, coal price, many-sided reasons such as the easy spontaneous combustion of low sulphur coal, the working barrier of promoting low sulphur coal is very big, effect is undesirable at present, if from the source of goods, price, many-sided particular case such as transport power is seen, other city at home, it is unpractical adopting the way of promoting low sulphur coal fully, and the measure of fuel oil is used in the whole nation instead, because the restriction of fund and other condition, also difficult in a short time the realization, proceed from reality, on the existing coal-fired basis, carry out the efficient environment-protecting coal product companion, solving the scheme of coal burning pollution, will be to select preferably under the existence conditions.
2, social benefit
Environmental protection coal companion's application, being one is the important channel of reducing the main source of atmospheric pollution by the major measure of the dirty energy to the clean energy transition, and the M ﹠ M of relative disease reduces 0.5-12.5%, and simultaneously, energy-saving efficiency is up to 15-20%.
One, dirty principle is fallen
1, oxysulfide (SO
x) remove
Owing to contain sulphur in the fire coal, in combustion processes, can produce the oxysulfide of pollutant atmosphere, coal companying additive as sweetening agent, should reach the purpose of solid sulphur, desulfurization with the big metal strong oxidizer of activity by chemistry side.
2, oxynitride (NO
x) removal
Oxynitride is nitrogen protoxide (NO) and nitrogen peroxide (NO
2) general name, NO accounts for about 95% in the flue gas, coal companying additive is that oxynitride is changed into free of contamination nitrogen, simultaneously, removes oxynitride with reduction and absorption pattern.
3, the removal of carbon monoxide and hydrocarbons
Coal companying additive can promote the mode of perfect combustion, reduces the quantity discharged of carbon monoxide and hydrocarbon polymer.
4, the removal of flue dust
Add coal companying additive, stove internal combustion situation is improved, and the flammable composition of coal fully burns, not over-emitting black exhaust, air blast or induced draft fan are opened for a short time, gas velocity is little, and the corresponding minimizing of the grit of taking away makes slag be bulk shape, grit is difficult for scattering, in addition, fine sulphate particles and agglomerative sulfuric acid aerosol such as solidify in the slag at factor, have reached removal flue dust effect.
Two, energy-saving principle
It is about 60% that coal companying additive contains the oxygen composition, and wherein Potcrate goes out oxygen through Manganse Dioxide catalysis decomposes, can be combustion-supporting.
Three, prevent the loss principle of coal firing boiler
Boiler body is made up of steel plate and pipeline, owing in the atmospheric oxidation environment,, the interior steel and iron member of stove is got rusty, constantly comes off with acid and metallic contact generation electrochemical reactions such as tin, copper, and constantly corrosion, thus make boiler body generation loss, reduce work-ing life.
Coal companying additive can remove oxysulfide in the flue gas, oxynitride more than 50%, has reduced the acid atmosphere in the stove, and utilizes active bigger metal; as zinc, magnesium or iron contact; make like this in the electrochemical reaction of iron to become negative electrode, do not lose electronics and be protected, avoid corrosion.
Coal is circuitous water vapor in high-temp combustion, then forms water-gas, and wherein carbon monoxide can be an iron with iron oxide reduction as reductive agent.
The coal companying additive preparation method is uncomplicated; easy to use; no aggressiveness, cost is low, and the user need not transform existing installation; good effect for purifying air; smoke abatement makes coal combustion stronger, more abundant, and energy-saving effect is remarkable; metal heat transfer to the combustion space has provide protection, has promotional value.
The drawing of accompanying drawing is described as follows:
Fig. 1: the preparation method of coal companying additive
The present invention will now be further detailed embodiment:
Embodiment:
30 kilograms in potassium permanganate and Manganse Dioxide were mixed 1.5 minutes for 15 kilograms, add 5 kilograms in Potcrate, mixed 1 minute, add 15 kilograms of potassium bichromate, mixed 1 minute, and added 10 kilograms in salt of wormwood, mixed 1 minute, add 5 kilograms in magnesium oxide, mixed 1 minute, and added 5 kilograms in zinc oxide, mixed 1 minute, add 15 kilograms of calcium superphosphate, mixed 5 minutes, enter worm conveyor, cone-type mixer, worm conveyor, storage tank, the electronics metering packing, sack closer, finished product warehouse-in.
In the boiler house, Chengdu, added 0.2% coal companying additive, by Sichuan Province Environmental Protection Agency, Chengdu Environmental Protection Agency tissue detects atmosphere, and the result is as follows:
