Product Description

 Coal Rotary Drum Dryer 

Product Description

^{Zhengzhou Jiutian is the most professional, authoritative enterprise in China, which is engaged in coal drying equipment research and development, which is the only Chinese coal slime drying industry set design, production, and sales in the integration of science and technology enterprises. After nearly 20 years of rapid development, Jiutian has gradually become the first brand of the Chinese drying equipment industry in China. Our company is based on lignite, washed coal such as high moisture content coal, with careful technical research and practice, developed the coal rotary drying drum system, After 20 years of drying experience and constant improvement in the equipment design, with its advanced technology, high efficiency, low energy consumption, stable operation, convenient operation and maintenance, security, environmental protection, the product are well received by users, more than 100 sets of coal drying equipment running in China and all over the world.}


  The Coal Dryer uses a special dispersing device to break up the bonded slime and dry it. The contact area between the slime and the hot air is increased, and the heat utilization rate is greatly improved. The dried slime can reduce the moisture to less than 12% at one time, and the dried coal slime can be directly used as a fuel, which makes the coal slime into treasure.


^{This type of equipment can be used for drying all kinds of coal, lignite, and carbon coal, including anthracite, lean coal and poor lean coal, lean coal, coking coal, fat coal, air fertilizer coal, gas coal, coal and weakly caking coal, not sticky coal, long flame coal, lignite, coal washing, screening, raw coal, bituminous coal, the tail coal, midding coal, etc. Equipment can be made according to the customers' requirements.}

 

Working Principle

Coal drum dryer is mainly composed of 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 operation control system. Equipment used downstream drying process, its working principle is as follows: wet material after entering the drying drum divided into the following workaround:

1. Feeding area, the coal into the area exchanged with high temperature and hot air quickly evaporates moisture, the material in a large Angle of guide plate copy, to be imported under a workspace.

2. Copy plate area, the coal in this area is copied by copy board forming curtain material, the material with good contact with hot air, the moisture in coal rapidly evaporation and becomes water vapor, water vapor is siphoned off by an induced draft fan, to achieve the aim of coal drying; The moisture of coal in this area is less than 15% (or less) under state of loose, after heat exchange the materials achieves the required moisture state, and discharging out.

3. Discharging area, do not set a copy plate roller in the region, the material in this area scroll taxiing to the discharge port, then complete the whole drying process.

 

Product Features

<sup>Technical structural characteristics of coal drum dryer
1. The coal fixed-speed quantitative feeder solves the problem of coal feeding and uniformity of travel in the dryer, and overcomes the previous problems of intermittent feeding, material blocking, and large instantaneous material volume. It is the prerequisite for improving the evaporation intensity.
(1) Design a unique buffer silo and feeding mechanism to overcome the problem of intermittent feeding or sudden large and small changes caused by uneven material supply;
(2) A large-inclination unpowered screw propeller is installed at the feed end of the drum, which not only sends the wet coal slime evenly into the drying section of the drum, but also further cuts and breaks up large pieces of wet coal slime;
2. Optimize the design of the internal structure of the dryer to maximize the heat exchange area between the material and the hot air quality, which is the basis for improving the evaporation intensity.
(1) Continuously optimize the design of the internal structural layout of the drum and the lifting plate, and finally finalize it into the current unique internal lifting plate structure of the drum and the mixing section layout with different functions. The "material" of the entire section of the drum is even and has no dead ends or gaps. Maximize the heat exchange area between coal and hot air, causing the moisture in the coal to quickly heat up, vaporize and evaporate, and be taken away by the hot air;
(2) Original patented technology for layered drying of rotary drum dryer. According to the rules that granular materials of different sizes are heated and travel at different speeds inside the drum, a multi-component layered drying device is set up with a large grate to control the powdering of small granular materials due to over-drying and the uneven heating of large granular materials inside and outside. Uneven drying ensures drying uniformity.
3. Reasonably select the type of hot blast furnace, optimize its internal structure design and masonry quality, reduce the air leakage rate, reduce the oxygen content in the hot air to less than 5%, and adjust the temperature point at any process requirement of 700-1100°C at will, which is the dryer Providing a homogeneous and stable heat source is a reliable guarantee for the high-intensity operation of the coal dryer.
4. The measurement and control technology system adopts a computer operating platform and frequency conversion PLC control technology. Process parameters such as temperature, pressure, oxygen concentration, and equipment speed are online interlocked and jointly controlled to realize automatic detection and control of the entire system. It has centralized and local switching functions to ensure The system operates stably with maximum output, best quality, most energy-saving mode, safety and explosion-proof.
5. Optimize the configuration of gravity sedimentation + cyclone dust collector + wet/bag dust collector three-stage dust collection and dust removal equipment. The dust concentration is <30mg/Nm3 to ensure that the exhaust gas emissions meet the standards.
6. The first modular design, manufacturing, transportation, installation, service concept and assembly and test platform to reward customers with more optimized design and manufacturing, more convenient transportation and installation services, and ensure maximum customer benefits.
7. Solve the problem of water vapor returning to the material as the system temperature decreases during the co-directional movement caused by the traditional dryer's downstream dehumidification, improve the drying efficiency, and achieve the purpose of deep dehydration.
8. The dryer adopts fish scale or labyrinth, expandable graphite filler type mechanical seal double sealing mode to ensure the dryer system is airtight and oxygen-free and operates safely.</sup>
