Product introduction:
The traditional by carbonate zinc oxide production of the main production methods: one is to adopt the shaft kiln, 2 it is to adopt rotary kiln. production
Out of zno low activity, high energy consumption and environmental pollution and material waste is serious. Adpt company dynamic dry calcination process
Equipment, can produce highly active, high purity zinc oxide. Zno flash drying calcining stoves have energy-saving, environmental pollution, back
Accept high efficiency, cover an area of an area small, the advantages of high degree of automation.
Working principle:
By dynamic stoves calcining stoves calcining material production, after the exhaust gas entering drying machine, by DE within 30 ~ tape feeder will moisture content
50% of the filter cake shape carbonate zinc into dryer, the dry powder of carbonate formation scattered into dynamic calcined furnace zinc, by burning
Coal and gas or coal gas produced hot air into the calcined furnace, with the carbonate zinc send charging in heat transfer, the mixed
400 ~ 1000 ℃ hot air heating, carbonate zinc by rapid decomposition for a few seconds after decomposition of zinc oxide, by capture
Trap set into storage.
Characteristics:
1. Decomposition temperature uniformity fast, may realize the pre-haart high-purity zinc oxide production, active > > 99 80, purity.
2. But the filter cake shape carbonate zinc in a sets system production powder zinc oxide.
3. Production product heat consumption of 150 to 200 x 104kcal/ton.
4. Environmentally friendly, cover an area of an area small, convenient in maintenance operation, high degree of automation.
5. Recovery > 99%
6. Technology reform tons costs can drop 1500 yuan.
Technical specifications:
In the series model range single sets zno production for 1000, 2000 and 3000, 5000 tons/year
