Abstract

The invention belongs to the technical field of coal ash, in particular to a coal ash separation and conversion device. The invention mainly includes main air inlet, auxiliary air inlet, coal ash outlet, return pipe, cyclone separator, coal outlet, air inlet, outlet elbow, cylinder body, collision rod, coal hopper, feed pipe, screw pusher Machine, coal ash separator, return material control valve, coal unloading valve. There are 4-24 adjacent collision rods with an included angle of 90º-15º in the cylinder, which are made of high-performance materials with high wear resistance, high strength and low linear expansion rate; The turbulent flow in the cylinder strengthens the collision and improves the separation effect of coal ash.

Description

technical field [0001] The invention belongs to the technical field of coal ash, in particular to a coal ash separation and conversion device. Background technique [0002] At present, all coals contain ash, and some coals have high ash content, which seriously affects the efficient application of coal. Most of the boilers of large enterprises such as steel mills and power plants use pulverized coal combustion technology, and a large amount of fly ash is discharged every year. These ash often contain unburned coal, and some of them contain quite high carbon content, which is a waste of energy. Especially when coal is used as raw material to produce other industrial products, ash seriously hinders the conversion of coal, and the composition of ash is complex, which affects the product quality of coal conversion. After the coal and ash are separated, and then the coal is used as energy or raw material, the degree of coal utilization will be greatly improved; the products prod...
