Abstract
The invention provides a clean fired coal saving agent with the effects of sulfur fixation, dust fall, heat increment and coal saving which is prepared and produced by industrially produced waste liquid and waste residues and chemical and mineral product raw materials. The clean fired coal saving agent is divided into two forms, namely a liquid product and a powder product; the liquid product is obtained by dissolving sodium nitrite, potassium nitrite, potassium nitrate, sodium nitrate, sodium sulfonate and sodium dodecyl benzene sulfonate into mixed liquid of paper making black liquid, alcohol waste liquid and fired coal fume water film dust removal and desulfurization alkali regeneration fluid; and the power product is obtained by absorbing and preparing the liquid product by utilizing hot fired coal slag, then allocating the chemical and mineral product raw materials and finally uniformly mixing, drying and crushing. The invention achieves cyclic resource utilization of industrial wastes, effectively solves the difficult problems of complete control of fired coal pollution and paper making and alcohol waste liquid pollution, has the advantages of innocuity, odorless, no three-waste emission, no increased investment and convenient operation and can use the device required not to be improved, save the coals per ton by 20-50 yuan and be used for all industrial and civil fired coals.
Description
Technical field:
The present invention relates to a kind of clean fired coal saving agent that utilizes black liquid, alcohol slops, coal-fired flue-gas dust removal with desulfurization by water film waste liquid, waste residue preparation to produce a kind of efficiency of sulfur retention, depositing dust, the gain of heat, economize on coal.
Background technology:
Rich coal resources in China, it is the big country of world's producing coal and consumption of coal, because China's economic construction is extensive high energy consumption, the Development patterns of high pollution, make China's economy when increasing, pay huge Energy resources cost, the serious environmental cost of pollution.For stopping this trend, and at the specific national conditions of the vast middle-size and small-size coal-fired enterprise of China, development is efficient, clean coal-saving agent researchs and develops especially that to utilize industrial production to produce a large amount of liquid and waste slag produced, it mainly is the black liquor that the paper mill produced, the waste liquid that Alcohol Production produced, coal-fired flue-gas dust-removing and desulfurization is administered the waste liquid that is produced, cinder production preparation clean fired coal saving agent, it is a little instant effect of investment, high efficiency, can produce a huge treatment of wastes with processes of wastes against one another, the technological invention of the new technique industrial colony of turning waste into wealth has not yet to see the relevant black liquid that utilizes, alcohol slops, the liquid and waste slag produced technology report that is used to produce the preparation clean fired coal saving agent of coal-fired flue-gas dust-removing and desulfurization.
Summary of the invention:
The purpose of this invention is to provide a kind of utilization is main base-material raw material with paper mill black liquor, alcohol slops, the coal-fired slag of coal-fired flue-gas dust-removing and desulfurization waste liquid and mineral products, allocates the method for a certain amount of industrial chemicals production preparation clean fired coal saving agent into.Reaching the treatment of wastes with processes of wastes against one another, turn waste into wealth, efficiently to utilize, Gu sulphur, depositing dust, the gain of heat, the effect of economizing on coal.
The technical solution adopted in the present invention:
Clean fired coal saving agent is divided into liquor, two kinds of form products of pulvis.Earlier the waste liquid with various productions dischargings is concentrated to certain concentration range, and the coal-fired slag after coal-fired flue-gas dust removal with desulfurization by water film waste liquid alkali manipulation of regeneration liquid and the perfect combustion as main raw material, is mixed with the clean fired coal saving agent of liquor type with industrial chemicals; Reusable heat stove cinder absorbs the liquor product and mends chemical mineral product raw material drying and pulverize the clean fired coal saving agent that promptly obtains pulvis.
The raw material of clean fired coal saving agent liquor is formed and part by weight is:

The compound method of clean fired coal saving agent liquor product:
With Sodium Nitrite (NaNO
2), potassium nitrite (KNO
2), saltpetre (KNO
3), SODIUMNITRATE (NaNO
3), dissolve in black liquid or coal-fired flue-gas dust removal with desulfurization by water film regenerated liquid, alcohol slops behind the industrial chemicals uniform mixing such as Sodium dodecylbenzene sulfonate in proportion in spissated mixed concentrated liquid, stirring fully, dissolving back barrelling promptly gets the liquor product.
The compound method of clean fired coal saving agent powder product:
Hot coal slag with after-flame fully absorbs the liquor product that has been mixed with, allocates Sodium Nitrite (NaNO after drying into
2), potassium nitrite (KNO
2), saltpetre (KNO
3), SODIUMNITRATE (NaNO
3), Manganse Dioxide breeze (MnO
2), ferric oxide breeze (Fe
2O
3) pulverize the back pack that stirs and promptly get powder product.
The preparation method of coal-fired flue-gas dust removal with desulfurization by water film alkaline regeneration solution:
Coal-fired flue-gas dust removal with desulfurization by water film circulation fluid is placed the settling tank sediment, get then in the supernatant liquor suction agitator, under condition of stirring, add lime putty, when acidity-basicity ph value reaches 10-14, with regenerated liquid suction frame filter, the stillness of night of discharge is coal-fired dust removal with desulfurization by water film alkaline regeneration solution stock liquid.
The solids of discharging from pressure filter after depositing oxidation as building materials with and the gypsum raw material used of manufacture of cement.
The clean fired coal saving agent that adopts the technology of the present invention method to produce uses on various fire coals, and can obtain following clean coal saving combustion effect: sulfur-fixing rate is at 30-70%; Dust reduction rate is at 30-60%; Coal saving rate at 10-35%, subtract carbon emission 10-35%.
The present invention realize black liquid, alcohol slops, coal-fired dust-removal and desulfurizing waste liquid and coal-fired slag utilization fully, reach zero release, the treatment of wastes with processes of wastes against one another, turn waste into wealth.It not only effectively solves coal burning pollution and papermaking, alcohol slops and pollutes three big world property difficult problems of thoroughly administering, and has solved these liquid and waste slag produced new ways of utilizing, and the raw material of abundant cheapness is provided for the additive for fire coal market of heavy demand simultaneously.This clean fired coal saving agent is nontoxic, odorless, not spontaneous combustion, do not explode, non-corrosiveness, three-waste free discharge, applicable to the fire coal of various stoves.Use and not need reforming equipment, do not increase investment, do not increase the production use cost, a ton coal can save and prop up a 20-50 unit, and easy to use, operative technique is simple, can use in all industry and civil, reaches the high-efficiency multi-function energy-saving and emission-reduction, subtracts the purpose of carbon.
Embodiment:
Clean fired coal saving agent is divided into liquor, two kinds of form products of pulvis, liquor product industrial chemicals Sodium Nitrite (NaNO
