High Efficiency Zinc Oxide Rotary Kiln Production Line
Rotary kiln Usage and applicatioin :
Zinc oxide rotary kiln calcines zinc-containing flue ash, iron slag, non-ferrous smelter containing zinc flue ash,
blast furnace ash, zinc ash and other zinc containing raw materials (zinc content 8-20%, lead 2-8%, arsenic less than 1%, sulfur less than 1.5%,silver is greater than 20g/t).
Zinc oxide (Zn45-60%,Pb5-8%) was obtained by oxidation roasting and reducing zinc vapor and hot air oxidation at high temperature (1000-1100 ºC) in rotary kiln. Residue calcined in rotary kilns (lead 0.3-0.5%) ,zinc 1-2%, iron 20-30%) can be sold in cement plants or magnetic separation iron.
Rotary kiln Working principle:
The main components of the whole set of equipment is feeding system, rotary kiln system, slag water system, dust collecting system.
The high temperature (750 ºC) delivered by the rotary kiln and the gases containing various partial oxides and dust are separated for the first time in the settling chamber to dissipate heat and continue to oxidize;
The specific gravity of this dust is larger than that of oxide through the oxide and some dust brought by the cooled gas (300-400 ºC).
The second separation and cooling (temperature < 160 ºC) are achieved through more than 11 groups of multi-tube coolers. About 160°and with very strong oxide and dust gas are carried out by pulse method, dust is separated and cooled, dust falls into ash hopper, gas enters the desulfurization tower, and the temperature drops below 60 ºC.
To bring the The sulfur dioxide gas and other gases entering the desulfurization tower flow upward from the bottom of the tower, while the lye flows from top to bottom in a three-stage mist flow, and moves upward through the change of direction of entry and deceleration of the third stage hollow ball, The final sulfur content of the discharged gas should not exceed 400 mg.
After neutralizing with acid and base, calcium sulfite precipitate will be produced. The water slag will be separated and caged by filter press, and calcium sulfite will be removed as waste residue.
Rotary Kiln Features:
1. Advanced structure, good sealing, the kiln head is sealed by the shell, and the kiln tail adopts the axial contact seal which ensures the sealing is reliable.
2. Easy to install and maintain; large kiln equipped with the auxiliary drive to meet the needs of installation and maintenance.
3. The rotary kiln with large unit volume, long furnace life, stable operation, high heat transfer efficiency, and low heat consumption.
4. The rotary kilns offer a robust and reliable design that delivers the benefits of low resource consumption and high operational reliability.
