Abstract

The invention relates to a device for drying and sieving coal by wind power. The device comprises a dryer, a sieve, a negative pressure forming component and / or a positive pressure forming component, wherein the sieve is arranged below or above the dryer in the hollow main body, the hot wind for the dryer can be obtained from inside a coke oven, thus saving quantities of energy.

Description

technical field [0001] The invention relates to a device for drying and screening coal by wind power. Background technique [0002] The quality of blast furnace coke mainly depends on the two main indicators of its mechanical strength and post-reaction strength, and the main factors affecting these two indicators are the coke's pore structure, pore wall strength, coke cracks and coke optical structure, these factors In addition to the optical structure of coke depending on the inherent properties of coal, several other factors mainly depend on whether the coal particles in the furnace are uniform and the degree of refinement. At the same time, fine-grained furnace coal can also increase the coke output. The ideal range of particle size distribution of furnace coal is that the particle diameter is between 0.5-3mm. The upper limit value should be determined with reference to factors such as raw coal lithofacies composition and heap specific gravity. Combined with the principle...
