【Supply lignite dryer] large-scale the lignite dryer scheme / lignite dryer manual lignite in the context of increasingly tense domestic coal resources is a new development and utilization pathway, lignite drying and quality and the country is also a new urgent breakthrough, coal drying experts Dongding dry in many years engaged in the slime, clean coal and coal dewatering drying accumulated a wealth of experience and theory and practice. Engineering and technical personnel of the Division I for the characteristics and use of lignite point to address a range of safety, environmental issues, the successful development of a dedicated lignite dryer device, the system is a vertical drying in the country after the Division I both developed slime dryer device the field is a major breakthrough, greatly expanding the use of lignite ways. Its technical characteristics: (1) dry lignite do not get damp absorbent larger physical and chemical changes occurred: dried lignite pores collapse, the cross-linking reaction and tar migration of pores form a seal results lignite becoming increasingly hydrophobic, and also able to observe that 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.
