Pneumatic ash conveying system

Double casing concentrated phase positive pneumatic ash conveying system Double-casing concentrated phase positive pneumatic conveying system is an advanced pneumatic conveying technology, which is developed in abroad in1980s. It is widely used in power plant fly ash, cement, limestone powder, aluminum powder, gypsum powder, pulverized materials, such as pneumatic conveying industry. Double casing concentrated phase positive pneumatic conveying system mechanism is different from the conventional positive transmission. Conventional positive pneumatic conveying system uses the suspension delivery, the transmission concentration is low, high-speed, easy to wear and possession of Plugging; Double casing concentrated phase positive pneumatic conveying system uses the hydrostatic transmission, has a high ash/ gas, and large efforts, low-velocity, small wear, etc., is the ideal solution to transport the high wear and efforts, dense phase conveying heavy wear materials (such as boiler fly ash), on behalf of today's advanced technology level . In the normal running conditions, the system automatically adjusts the double casing to loose the big fly ash, so that make sure the fly ash transported in steady-state and prevent the tube from blocking. The features are as following: 1.The system operation is reliable, not possession of Plugging 2.Power exhaust is small 3.Long-distance, large load 4.Low velocity, low wear and tear, little maintenance workload 5.Advanced dedicated valve 6.Adequate efforts of the system 7.Reasonable means to eliminate the lack ; 8.Optimized system configuration 9.Intelligent Control
