Pulverized Coal Product Introduction
Pulverized coal dryer is also called rotary drum dryer, which is widely used in building materials, metallurgy, chemical industry, cement industry to dry slag limestone, pulverized coal, slag, clay and other materials. Coal powder has high humidity and high cohesiveness, which is not conducive to storage. The pulverized coal after drying by the pulverized coal dryer can be directly used as fuel, so that the pulverized coal can be reused.
Features of pulverized coal dryer:
1. The pulverized coal dryer adopts a new device combination mode, which has strong anti-overload ability and large processing capacity.
2. The new pulverized coal hot blast stove has a thermal efficiency of 99%, low fuel consumption, low energy consumption, and low drying cost, which is 3/5 of the ordinary rotary dryer. At the same time, it can be equipped with various types of furnaces such as gas generator, oil-fired hot blast stove, and chain row furnace;
3. The pulverized coal dryer adopts the downstream drying method. The flue gas and the wet material enter the drying equipment from the same side. The high-temperature flue gas can be used to obtain high evaporation intensity. The outlet temperature of the dryer is low and the thermal efficiency is high. The material can form a stable full-break fabric curtain in the dryer cylinder, the quality and heat exchange is more sufficient, and the production efficiency is high.
4. The pulverized coal dryer can change the operating parameters according to the properties of different materials, and has strong adaptability, so that the material can form a stable full-break fabric curtain in the dryer cylinder, and the quality and heat exchange is more sufficient;
5. The new internal structure, different drying sections are provided with different copying and cleaning structures, which can solve the problem of sticking to the wall and achieve good drying, and can also control the particle size of the dried product to prevent the product from being too large or too fine. , to ensure product quality.
Working Principle of Pulverized Coal Dryer
The pulverized coal drying process is mainly divided into the following working areas:
The first is the material guide area: the wet pulverized coal enters this area and contacts with the high-temperature hot air to quickly evaporate the water, and the material will be introduced into the next working area without forming a bond under the large-angle copying plate copying;
The second is the dispersing area: the pulverized coal is dispersed by the dispersing device in this area, thereby increasing the heat exchange area between the coal slime and the hot air;
The third is the inclined lifting plate area: the crushed wet pulverized coal is lifted by the lifting plate in this area to form a material curtain state. At this time, the material is in contact with the hot air, and the moisture in the wet pulverized coal quickly evaporates into water vapor. The steam is then drawn away by the bow and fan, so as to achieve the purpose of drying; when the material falls, it is easy to form the phenomenon of sticking to the drum wall. The equipment in this area is designed with a cleaning device, and the cleaning device can reasonably clean the material adhered to the inner wall; wet coal The powder is dried into a loose state with low moisture in this area, and after heat exchange, the material reaches the required moisture state and enters the discharge area;
The fourth is the discharge area: the drum does not have a copy plate in this area, and the material rolls and slides to the discharge port in this area to complete the entire drying process.
Advantages of Pulverized Coal Dryer Equipment
1. Reliable operation: The pulverized coal dryer achieves "zero horizontal thrust", which greatly reduces the wear of the retaining roller, and the equipment runs stably and reliably.
2. Make full use of energy: the downstream drying method is adopted, and the hot air and materials enter the slime dryer from one side at the same time, which can effectively utilize the high-temperature hot air.
3. Energy saving and environmental protection: The pulverized coal dryer is fully sealed, which effectively reduces heat loss and dust emission. At the same time, it is equipped with a multi-stage dust removal system, which can prevent users from preventing them again.
4. Intelligent and efficient: Plc intelligent centralized The control system is easy to operate, with high precision, and the equipment cooperates tacitly, which greatly improves the drying efficiency.
5. The structure is reasonable and the work is guaranteed: the new internal structure, feeding and discharging devices strengthen the cleaning and heat conduction of the dispersed materials, eliminate the adhesion phenomenon of the inner wall of the cylinder, and prevent the feeding blockage and discontinuity. The phenomenon of unevenness and reverse material reduces the load of the dust removal system.

| Note: The equipment production capacity and lignite removing water moisture content directly related. If a large proportion of water removed, equipment capacity correspondingly reduced. As the lignite formation of the difference, the Indonesian lignite moisture is generally 40- 65%, Inner Mongolia lignite water is generally 25- 42%, Yunnan lignite water is generally 30- 45%.
