Limestone Calcination Equipment Vertical Preheater Large Scale Convenient Maintenance
Vertical Preheater Introduction:
The vertical preheater is a vertical preheating device that preheat calcined material, it’s developed on the basis of import and absorb advance technology from abroad and combine with dolomite and limestone calcination features, with characteristics such as rational structure, high rate of heat exchange, high level of automatic. It main used to preheat raw material with poor thermal stability (such as limestone, dolomite and so on). The vertical preheater is used with rotary kiln, make the high temperature air from kiln tail fully utilize, play a role in saving energy and reducing consumption, it’s a energy saving and environment - friendly product.
Vertical Preheater Structure:
Vertical preheater is consist of upper feeding system, suspended ceiling device, main body, pusher system, hydraulic system and so on. Concrete structure such as below drawing. The characteristics of each sub-system is:
1. Upper feeding system
It main include upper hopper, discharge chute, hopper legs and so on, its main role is to ensure complete sealing when feeding materials into main body of preheater, and avoid cool air enter into preheater.
2. Suspended ceiling device
Its main role is bearing the weight of hanger bricks.
3. Main body of preheater
The main body of preheater is consist of preheating room, hanger device and so on, it’s the key part of ensuring materials preheated more than 800℃.
4. Pusher system
Include push head, liner support frame and so on, to ensure push materials steady, reliable and accurate.
5. Hydraulic system
Include oil box, oil pump, motor, electro magnetic valve, hydraulic oil tube and so on, it’s main used to control pusher device, complete push action.
6. Bottom feed hopper
Include feed hopper and so on, its main used to import preheated materials into rotary kiln by transfer chute for calcination.
7. Recycle system
Include dust collection silo, recycle slide pipe and so on.
Our Advantages of Dolomite Vertical Preheater:
1. Push head and main parts of body is made of heat resistance steel, so it can work in 1000~1100℃ high temperature, and have long operation life.
2. Effectively recycle heating energy in waste gas from kiln inlet, to insure the material is preheated equally and reach to preheating temperature.
3. Recycle the heat energy in waste air that discharge from kiln tail effective, increase utilization ratio of fuel, at the same time, it’s benefit to dedust;
4. The vertical preheater is used in calcination system, the length of rotary kiln will be shorten, to reduce the heat loss on the surface of rotary kiln and floor space;
5. With good combined revenues, the capacity will be increased 30%, thermal efficiency will be increased 40% after use vertical preheater.
