Professional integrity and innovation, Dongding always conscientious service to the majority of the owners of a friend, about 800 tons of lignite dryer technology exchange, medium lignite dryer principle process consulting to Dongding dry, efficient and environmentally friendly energy-saving design of lignite dryer fully consider the nature of the drying material for the high water content of lignite cylinder internal structure specially designed to further strengthen the anti-broken unity block materials, not only to improve the thermal efficiency, but also effectively avoid coal in dry machine over dry phenomenon. 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. Lignite dryer principle: to be after the crushing of the dried lignite transported by the belt conveyor to feed box, and then slide the guide plate by a big dip in the tumble dryer to quickly oriented tilt lifting area, and with the drum rotation the inclination of the cylinder, since raised to the top of the barrel cylinder bottom fall, the formation of a "material curtain" through the drying drum with the same end of the wet material into high temperature flue gas from the wet material to form a conductive liquid heat exchange, preheat The wet material and evaporation of the water. Meanwhile, the high-temperature flue gas temperature is decreased rapidly, by preheating the wet material into the medium-temperature drying stage at this stage, most of the moisture is evaporated. Until they reach thermal equilibrium with the material and repeated mixing of the flue gas exchange, material moisture requirements, the material is discharged drying drum. The interior of the drum copy board strip pore structure, lignite took a process in the interior of the drum, and continue to leak, both to increase the lignite and the contact area of ??the hot flue gas, and to avoid being took a too high disposable whereabouts cause rupture, significantly reduce the amount of montanic secondary crushing. Copy board between the level of scattered layout, has a certain angle with the cylinder axis, both continuous material curtain so he took a lignite formation, but also make the dry material continuously advancing to the discharge end to form a continuous drying. Are made of thin stainless steel plates sealed drum front head and the back-end head drum, stainless steel plates outside using Lahuang drum outside seal closed, this sealing method can be high temperature, no noise, no leakage gas, is a novel sealing manner. After heat exchange, contains a lot of water vapor and dust exhaust after cyclone was removed most of the dust into the bag filter purification, the exhaust direct emissions purified form the entire drying process.
