Vertical dryer's structure:
The vertical dryer adopts vertical equipment and steel structure housing, the lining is equipped with heat preservation material to keep warm, in the inner of the kiln, and multilayer high temperature castings have been used and overlapped. In the higher, middle and lower parts, all relevant components have several groups of vibrate, closure, temperature control and intelligent control systems. Water vapor and smoke collected and removed by the whirlwind dust collector installed in the draught fan.
Vertical dryer's principle:
The key technology of vertical dryer is to control the flow rate and residence time of the material in every area of the dryer, making the hot flue gas fully convected, radiated and heat conducted with the material which thus can be scattered in the dryer as far as possible to enlarge the contact area between the hot smoke and the material. At the same time, material drying parameter optimization microcomputer software technology has been adopted to proceed online detection to the material moisture and gas temperature in the preheating zone, stoving zone and drying zone, and adjust the system parameters on line such as heating ability, lead-wind quantity, secondary hot wind distribution, heat supply capacity, material closure capacity and retention time, etc., realizing dynamic optimization balance of the system and improving the heat utilization rate.
Vertical dryer's Advantages:
1.)Innovative design: new-style vertical of drying, the material is free dropping, gas material countercurrent operation, which is integrated gathering heat conduction and thermal radiation into a body .Heat efficiency is up to 93%. The whole process is automatic control, easy operation and maintenance.
2.)Less investment: apply small area, saving 80% of the investment, it is especially suitable for the old-line transformation. It can make use of abandoned or idle kiln, mill, tower, library and horizontal dryer, etc. further reducing the investment.
3.)Widely used: drying clay, slag, fly ash, coal, iron can also be used in mineral processing, chemical, foundry and other industries of material drying.
4.)Long life: the internal components used in all heat-resistant alloy, long life, low failure rate.
Vertical dryer's technology parameters:
