Description
Technical field
The invention belongs to additive for solid fuel, be specifically related to a kind of coal-saving synergist that is used for cement in vertical kiln.
Background technology
At present China's cement production enterprise mostly adopts and add composite mineralizer (fluorite adds gypsum) in raw material aspect energy-conservation, and effect of coal saving is not obvious, only plays mineralization.The producer that has adopts yellow phosphorus slag phosphogypsum, and effect of coal saving is also not obvious.The producer that also has adopts simple coal-saving agent (the ripe burning agent of so-called raw material)----potassium permanganate to add sodium-chlor and join fluorite etc. again, and their effect of coal saving is undesirable equally. and be considered to cost height (raw material per ton increase about 4 yuan cost) always.
Summary of the invention
The objective of the invention is problem, provide a kind of effect of coal saving good coal-saving synergist at the prior art existence.
The present invention seeks to be achieved through the following technical solutions:
Coal-saving synergist adopts following main ingredient and consumption (weight %):
Potassium permanganate 2.5-4.5%;
Saltpetre 1.5-3.5%;
Ammonium nitrate 0.5-2.0%;
Sodium-chlor 90.0-95.0%.
The effect of coal-saving synergist mainly is the combustion-supporting of coal.It is added to when burning in the raw material, and potassium permanganate, saltpetre and ammonium nitrate all can discharge oxygen, impel coal fully to burn, to reach the purpose of economizing on coal.Different components discharges stage of oxygen in coal combustion process different, begins to decompose at 200 ℃ as ammonium nitrate, and saltpetre begins to decompose at 350-450 ℃, and potassium permanganate then begins to decompose at 200-300 ℃.Each stage in the time of so just can making coal combustion all has additive to discharge oxygen, guarantees the abundant burning of coal to greatest extent.Sodium-chlor mainly as carrier, is made swelling agent and properties-correcting agent simultaneously.
Coal-saving synergist of the present invention can also increase some accessory constituents and become another prescription on the basis of said components, to obtain better effect of coal saving.This prescription adopts following component and consumption (weight %):
Potassium permanganate 2.5-3%;
Saltpetre 1.5-2.5%;
Ammonium nitrate 0.5-1.0%;
Sodium-chlor 80.0-85.0%;
Unslaked lime 2.0-6.5%;
Potassium perchlorate 1.5-2.5%;
Red iron oxide 1.0-2.5%;
Potcrate 1.0-2.0%.
In the said components, unslaked lime is used for solid sulphur, and potassium perchlorate begins to decompose at 400-600 ℃, discharges comburant oxygen, and red iron oxide is used for the adjusting that component discharges amount of oxygen, and Potcrate is used as swelling agent, and discharges comburant oxygens at 400 ℃.
The making of coal-saving synergist is very simple, and a need is determined concrete prescription according to the user's with the coal situation, and various components are mixed, and packing gets final product.
Can be during use according to the difference of coal, add coal-saving synergist of the present invention by the 0.02-0.05% of raw material.
The characteristics of coal-saving synergist of the present invention comprise:
1). can change the combustion system of original raw material, by peel off formula burning become inside and outside burning together;
2). improve the after-flame degree of fugitive constituent in the coal;
3). reduce the thermosteresis of interior chemical incomplete combustion of shaft kiln kiln and mechanical incomplete combustion;
4). the heat energy component in the perfect combustion raw material;
5) Gu. sulphur, reduce the influence of pollution substance to environment.
Result of use: after in raw material, adding coal-saving synergist of the present invention, can improve the coal calorific value more than 20%, coal saving rate 10-25%; Make 28 days ultimate compression strength of shaft kiln clinker improve 2-3MPa; Improve shaft kiln unit-hour output 8-10%; Reduce obnoxious flavour and smoke discharge amount 60-80%; Improve the grindability of grog.
