Product Description
Vanadium pentoxide dry calcining process
Vanadium pentoxide drying calcination is introduced:
Use dry, decomposition, rapid melting technology and equipment production of vanadium, is an internationally advanced level of processing equipment.
Step method:
Traditional process method is a one-step process, will be the early stage of the process of partial or more ammonium vanadate vanadium water filter cake put in reverberatory furnace, heating for a long time gradually complete drying, deamination, melting process.
One-step process is simple, the main problems
1. High energy consumption, energy efficiency is less than 30%.
2. The recovery rate is low, the recovery was 95% ~ 95% can achieve at present
3. The environmental pollution, vanadium of ammonia emissions into the air, causing air pollution
4. Working environment is poor, because of bad sealing of dust, smoke affect environmental and worker health
My company design of preparing vanadium three-step process
Three-step process, namely, drying, deamination, melting, three process is complete
1. First of all to pass through the dryer drying vanadium bread flour
2. The deamination equipment of removing ammonium
3. The melting furnace for melting
A dry,
Flash drying method, the vanadium bread by feeder into the drying machine, heating the hot air into the dryer.Under the influence of mechanical break up, make vanadium bread flour that rapid drying, form the powdery ammonium vanadate.
Second, the deamination
Using flash, achieve rapid calcination furnace ammonium, good dry powder ammonium vanadium off straight into the furnace, the heat of hot air into the ammonium in furnace, powdery vanadium fast mixing, with entering the furnace in a continuous flow achieve rapid decomposition, the decomposed into V2O5 powder vanadium dozens of seconds
Third, the melting
Mainly used in the melting process of three-phase electric arc furnace, melting furnace for radiating tube, flash smelting furnace.Radiant tube furnace, the flash smelting furnace is a new type furnace, rapid melting of vanadium mainly by flash melting chamber, heat preservation of molten pool.
New technology of three-step method
The three-step process can improve the efficiency of producing vanadium piece, the use of flash smelting furnace to produce dry hot air can be used as a heat source, the effective use of heat, and effective recovery of gasification ammonia in the air, with remarkable economic benefit.
Enterprise application case:
1. New vanadium titanium company chengde steel plant
2. Wuhan jianlong company
3. The shaanxi huayuan mining co., LTD
4. Thai tinplate alloy company
5. The shuangyashan jianlong company
