Attitude is a way out, excel innovation. The Dongding people always oriented to market customers, to create the highest quality products is our goal. Heilongjiang lignite dryer professional service providers Dongding drying the most scientific lignite dryer program. To mention the quality of lignite drying project background, rich in low-level lignite resources in China, due to the low degree of coalification of lignite, there is a high water content (20-50%), low calorific value, high volatile matter, poor thermal stability, high chemical activity, liable to spontaneous combustion, Inner Mongolia inadequate, resulting in a short radius of its sales (general 600KM range). The quality of the lignite resource itself determines its mining profits bottom situ conversion of lignite value-added. With the the Ximeng large-scale development of coal resources, comprehensive utilization of lignite put forward higher requirements. Lignite through the drying process can be achieved the lower lignite moisture, calorific value and heat density, lower transportation costs, and expand the the Comprehensive Utilization use of lignite coal, and improve the competitiveness of the coal mines in the market. Therefore, lignite dryer to mention the promotion of quality technology of lignite production areas is of great significance. Depth dehydration processing the system by way of thermal drying of coal products to effectively improve its calorific value indicators and reservoir shipment performance, so that the indicators meet the requirements of commodity thermal coal, has obvious economic, environmental and social benefits. The Dongding lignite dryer technical features (1) dry lignite not get damp absorbent: dried lignite larger physical and chemical changes in the pores collapse, the cross-linking reaction and tar migration of pores form a seal, the result lignite change more and more hydrophobic, and also be able to observe the hardening of the lignite, which also led to the formation of the rigid structure of the 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. (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.
