Program of the large systematic lignite dryer, the lignite dryer bidding quality service providers Dongding dry for your dedicated service, Division I of the lignite dryer form a standardized, serialized, 1000 tons of lignite dryer, 1,500 tons of lignite dryer, 2,000 tons of lignite dryer products solutions and services in large-scale power plant coal chemical industry. Efficient lignite drying to mention quality equipment lignite drying system Drying Equipment Co., Ltd., Zhengzhou City Dongding developed a new view of the above characteristics. The dryer design take full account of the nature of the dry material, specially designed for the high water content of lignite in the internal structure of the cylinder on, and further strengthen the unity block materials anti broken, not only to improve the thermal efficiency and effective avoid the coal phenomenon too dry in the dryer. The system through the processing of lignite drying and dehydration, which can effectively improve the the lignite heat indicators and reservoir shipment performance, so that the indicators meet the requirements of commodity thermal coal, has obvious economic, environmental and social benefits. The Dong Ding lignite dryer technical characteristics (1) dry lignite does not get damp absorbent: dried lignite larger physical and chemical changes, that the the pores collapse of the cross-linking reaction and tar migration pores form a seal, the result becomes lignite more and more hydrophobic, and also can be observed to the hardening of the lignite, which also led to the formation of the rigid structure of the lignite. As a result, lignite from soft coal is converted to hard coal, is hydrophobic and hydrophilic conversion to stamp out lignite dry damp absorbent, which can achieve the long-distance transport of lignite. (2) dry lignite volatiles are effectively protected: the humidity content uploaded wet media, no volatile release conditions; (3) a high degree of automation, simple manipulation: a high degree of system integration, and with automatic intelligent monitoring system , real-time monitoring of the parameters of the hot stove furnace, the entrance to the dryer, the dryer outlet and induced draft fan entrance of the main parts of the temperature, pressure, flame, smoke oxygen, the system runs automatically control and adjust the parameters for automatic acquisition, fault alarm and security interlock protection. Vibrating feeder, dryer, cited devices such as fans, blowers, spiral feeder with frequency control, according to the needs of production and operating parameters, using the appropriate speed, not only can easily control the final moisture indicators but also save a lot of power. (4) Energy efficient: dry heat loss (drying) machine, high thermal efficiency; heat source coal burnout rate of pulverized coal up to 99% of the hot stove, the effect of heat transfer efficiency than traditional coal-fired hot air furnace section Coal 30 --- 50%; lignite powder produced by the drying process can be used as a fuel, which greatly reduces the cost of fuel. (5) Safety: seamless wind phenomenon unique sealing structure to discharge completely solve the sealing difficulty to achieve full oxidation negative pressure operation to eliminate the possibility of lignite combustion and explosion, safe and reliable operation.
