Product Description

Advanced Coal Drum Dryer Equipment

Product Description

 

Zhengzhou Jiutian Technology Machinery Co., Ltd. stands as the pinnacle of professional expertise in China's coal drying equipment sector. Recognized as the sole enterprise in the Chinese coal slime drying industry to integrate design, production, and sales with advanced scientific research, Jiutian has crafted an unparalleled reputation over nearly two decades. Our relentless dedication to evolving coal drying technology, especially for lignite and high-moisture coal, has led to the innovation of the coal rotary drying drum system. Boasting cutting-edge technology, superior efficiency, minimal energy consumption, and robust, stable operations, our solutions are not only convenient and safe but also environmentally friendly. With more than 100 installations across China and globally, our coal drying equipment is celebrated for its exceptional performance.
 

The Coal Dryer features an innovative dispersing device designed to disintegrate bonded coal slime, enhancing its exposure to hot air and significantly boosting heat efficiency. This advanced mechanism reduces moisture content to below 12% in a single drying cycle, transforming once-wasteful coal slime into valuable fuel.
 

Our versatile equipment excels in drying various types of coal, including lignite, carbon coal, anthracite, lean coal, coking coal, fat coal, gas coal, and more. Whether dealing with sticky, non-sticky, long flame, or bituminous coal, our dryers are customizable to meet any customer specification, ensuring optimal performance across a broad spectrum of coal types.

 

Working Principle

 

The Coal Drum Dryer is an ingeniously designed and meticulously manufactured system, comprising a hot blast stove, belt feeding machine, drum dryer, belt discharging machine, induced draft fan, cyclone dust collector, bag filter (or wet dust collector), and an advanced operation control system. Utilizing a downstream drying process, its superior working principle encompasses the following stages:

1. **Feeding Area:** Here, the coal interfaces with high-temperature hot air, facilitating rapid moisture evaporation. The material is then guided by a steeply angled guide plate, preparing it for the next stage.

2. **Copy Plate Area:** In this section, the coal is lifted by the copy board, creating a curtain-like effect. Enhanced contact with hot air ensures swift moisture evaporation, transforming it into water vapor, which is promptly removed by the induced draft fan. This phase reduces the coal's moisture content to less than 15% or as required, achieving the ideal dryness level for discharge.

3. **Discharging Area:** This final stage is free from copy plates, allowing the material to glide smoothly to the discharge port, thereby completing the entire drying process efficiently and effectively.

 

Product Features

 

<sup>Technical Structural Characteristics of the Coal Drum Dryer
1. The coal fixed-speed quantitative feeder expertly addresses the challenges of coal feeding consistency and travel uniformity within the dryer. It effectively mitigates issues of intermittent feeding, material blockages, and large instantaneous material volumes, laying the groundwork for enhanced evaporation intensity.
(1) Ingeniously designed buffer silo and feeding mechanism to resolve intermittent feeding issues or sudden volume changes caused by uneven material supply.
(2) Features a large-inclination unpowered screw propeller at the drum's feed end, ensuring even distribution of wet coal slime into the drying section while also cutting and breaking up larger pieces efficiently.
2. The dryer's internal structure is optimized to maximize the heat exchange area between the material and hot air, ensuring improved evaporation intensity.
(1) Continuous refinement of the drum's internal structural layout and lifting plates has resulted in a unique internal lifting plate structure and a functionally diverse mixing section layout. This design ensures that the material is uniformly distributed, thereby maximizing heat exchange between coal and hot air, accelerating moisture vaporization and evaporation.
(2) Patented technology for layered drying in the rotary drum dryer. This advanced system ensures uniform drying by adjusting for different heating and travel speeds of granular materials, preventing over-drying of small granules and uneven heating of larger ones.
3. Careful selection and optimization of the hot blast furnace's internal structure and masonry quality reduce air leakage and oxygen content in hot air to below 5%. This allows precise temperature control between 700-1100°C, ensuring a stable and homogeneous heat source for high-intensity dryer operations.
4. The measurement and control technology system integrates a computer operating platform with frequency conversion PLC control technology. It synchronizes control over key parameters like temperature, pressure, oxygen concentration, and equipment speed, enabling automatic detection and control across the system. This ensures stable, high-output, high-quality, energy-efficient, and safe operations with explosion-proof features.
5. A refined three-stage dust collection system combines gravity sedimentation, cyclone dust collection, and wet/bag dust collectors to ensure dust concentration is below 30mg/Nm3, thus meeting stringent exhaust emission standards.
6. Pioneering modular design, manufacturing, transportation, installation, and service concepts ensure optimized design and manufacturing processes, more convenient transportation and installation, ultimately maximizing customer benefits.
7. Innovative solutions prevent water vapor from returning to the material as system temperatures decrease during co-directional movement, enhancing drying efficiency and achieving deep dehydration.
8. The dryer utilizes advanced fish scale or labyrinth, expandable graphite filler-type mechanical seal double-sealing for an airtight and oxygen-free system, ensuring safe operation.</sup>
