Abstract
The black pellet of calcining on lepol kiln.Change the heater of lepol kiln into three Room by two Room, i.e. drying chamber, preheating chamber, decomposition chamber.And draw the hot blast conduct from kiln hood and deceive the resolution ratio that the combustion air of pellet makes the coal charge catalytic combustion raising thermal efficiency and carbonate.Because the pellet CLAY MINERALS AND THEIR SIGNIFICANCE closely contacts with the lime stone mineral, provide decomposition phase and the condition that the chemical combination phase overlaps mutually simultaneously, made the very high very fast chemical combination of nascent state oxidation thing of activity of firm decomposition, and quicken the solid phase reaction of each mineral.Thereby significantly improve the grog yield and quality, reduce hear rate.
Description
The invention belongs to the new method of clinker burning
On the basis of the advantage of summing up lepol kiln and other kiln type, the creationary reforming rotary furnace scheme that proposed is the important breakthrough of lepol kiln technological innovation.Can consult the interrelated data of cement clinker calcining method research data and cement clinker calcining kiln type development.
All lepol kilns are all calcined white pellet at present, and main feature of the present invention is the black pellet of calcining on lepol kiln, and sets up decomposition chamber on heater, and draws the bed of material that combustion air blows to decomposition chamber by combustion fan from kiln hood, makes black pellet in the decomposition chamber internal combustion.Thereby outside kiln, increased thermal source, created condition for improving yield and quality, and coal charge catalytic combustion thermal efficiency height, calcium carbonate decomposition rate improved.And the condition that provides clay mineral and lime stone mineral decomposition phase and the each other rapid stage of reaction of these catabolites to coincide, make the very high very fast chemical combination of nascent state oxidation thing of activity of firm decomposition, and the hot pressing that effectively utilizes fuel combustion to produce, quickened each mineral solid phase reaction.This invention can significantly improve the yield and quality of lepol kiln and can reduce hear rate, because 60% fuel endangers healthy NO in lower temperature (1100 ℃) burning down in the waste gas
xIt is original 1/3rd that content can be reduced to, and reduces environmental pollution.
(1) coal powder injection pipe in the accompanying drawing, (2) fast firing, (3) decomposition chamber, (4) igniting chimney, (5) partition wall, (6) preheating chamber, (7) secondary is by blower fan, (8) partition wall, (9) drying chamber, (10) comb formula conveyer, (11) exhaust blower, (12) blanking scraper-trough conveyer, (13) combustion fan, (14) cooling cylinder, (15) pan-pelletizer, (16) flame.
Black meal is gone into drying chamber (9) after pan-pelletizer (15) balling-up, reenter preheating chamber (6) to decomposition chamber (3), and black material pearl is sent into the needed air of burning by combustion fan (13), goes into fast firing (2) after black pellet fully burns.Burn till grog through thermal-flame (16) and go into cooling cylinder (14).
Gas in the kiln is through the last chamber of decomposition chamber, by the last chamber of the flue on the partition wall (5) to preheating chamber, by blower fan the gas permeation bed of material preheating pellet of chamber on the preheating chamber is sent into the last chamber of drying chamber by double-edged fine-toothed comb chamber under the preheating chamber by secondary, the gas permeation bed of material oven dry pellet of chamber on the drying chamber is entered atmosphere by double-edged fine-toothed comb by exhaust blower.
Claims (4)
1, all lepol kilns are all calcined white pellet at present.This inventive features is not only to deceive pellet in the lepol kiln calcining, and sets up decomposition chamber [3] in heater.
2, introduce decomposition chamber (3) according to claim 1, combustion air by combustion fan (13) and blow to the bed of material.
3, according to claim 1, on decomposition chamber (3), set up the igniting chimney (4)
4, can draw cooling grog hot blast as combustion air from kiln hood according to claim 2, combustion fan.
