The present invention can utilize carbon containing bastard coal masonry carbonaceous reducing agent, and it provides AL simultaneously
2O
3And SiO
2Composition.This all is a composition useful among the present invention.Volatile component in the coal gangue is then taken away in the section volatilization back of heating up, and can not enter in the phosphoric acid absorption process, has guaranteed that phosphoric acid quality reaches the GB2091 requirement, reduces the phosphoric acid cost for purification.
Except that fuel, the present invention is industrial residue or mine waste residue with raw material, and good society and economic benefit are arranged.
Embodiment
Principle of work of the present invention is as follows:
The present invention finishes the reduction of phosphorus ore and the oxidizing reaction of phosphorus with the tunnel furnace for principal reaction equipment, absorbs by the smoke absorption tower to make phosphoric acid.The reduction of phosphorus ore as reductive agent, adds ground silica with carbon raw materials such as coke or coal or coal gangues, and kaolin participates in reduction reaction, generates Calucium Silicate powder (CaOSiO
2), tricalcium aluminate (3CaOAl
2O
3), they are the main components that form brick intention.
React as follows:
Phosphorous vapor and CO gas that reaction produces are supplied with quantitative O in kiln
2Make it to take place oxidizing reaction:
The oxidizing reaction liberated heat is used to keep temperature of reaction, can reduce firing rate, with save energy, reduces cost.
In order to prevent to expect carbon in the piece by premature oxidation, the present invention will expect piece dipping 1-3 layer glaze slip, and the atmosphere in the control kiln is weak oxide atmosphere.The glaze slip layer is by ground silica, kaolin, and the coke powder, methylcellulose gum, one or more cooperations in the polyvinyl alcohol etc. form.Can reduce the premature oxidation of coke in temperature-rise period, simultaneously weak oxide atmosphere helps the easy volatile material and overflows, and takes away when heating up 1220 ℃ of sections entering, and reduces the foreign matter content that enters the reduction section flue gas, improves phosphoric acid quality.
Technical process of the present invention is as follows: phosphorus mine tailing, ground silica, coke powder, kaolin, tackiness agent etc. are prepared burden in proportion, it is even to put into the old moisture string that makes in ageing storehouse behind the batch mixing, go into the drying kiln oven dry after using brick pressing machine (solid brick) or vacuum extruder (porous or hollow) moulding then, soak glaze 1-3 layer after the oven dry, tunnel furnace is gone in entrucking again.Pass through preheating, be warmed up to reduction and oxidizing reaction that 1400 ℃ of high temperature section are finished phosphorus, the reacted P that contains
2O
5Gas is in time derived through introducing the hydration tower after the interchanger heat exchange, with recycle acid absorb, cool off, filter finished product phosphoric acid.Receive the phosphoric acid purity height that day with fog is accepted, be directly used in and adjust the use of finished product acid concentration.Gas goes out to receive to reenter behind the day with fog puts into atmosphere after the fluorine recovery tower reclaims fluorine gas.Fragment of brick reaction finishes, and to draw off from the kiln tail through heat exchange cooling back be building brick both, and its quality meets the concerned countries standard-required.
Working process in the kiln of the present invention is as follows: soaks and shuts wicket after fragment of brick sign indicating number behind the glaze goes into to go into kiln on the kiln car, and all kiln cars parking stall of marching forward, the time in whole kiln is 〉=4 hours, wherein main reaction section time 〉=3 hour.In kiln, be warmed up to 1220 ℃ and cool to 1220 ℃ and set two zero-pressure forces.In preheating, the gas extraction that is warmed up in 1220 ℃ of temperature sections is used for drying kiln oven dry adobe; Gas at 1220 ℃ of-1450 ℃ of-1220 ℃ of temperature sections that heat up is to contain P
2O
5Gas, go into hydration tower system product after in time extracting heat exchange out; Being used for drying kiln oven dry adobe at 1220 ℃ of-60 ℃ of section gases of cooling with freezing air heat exchange extraction uses.In whole process, adopt the PLC automatic control technology, effectively control temperature, pressure, O in the kiln
2, CO, CO
2Concentration.Guarantee to react completely, reach energy saving purposes.
