Raised type coal particle environment-friendly drying equipment

Abstract

The invention discloses raised type coal particle environment-friendly drying equipment, and belongs to the technical field of coal drying. Coal particles can be flatly laid on a drying disc, and the traction effect of a linkage rod on a raised film is utilized, so that the raised film is raised upwards to softly turn over the coal particles, and meanwhile the raised film after being raised can effectively absorb heat on the outer side of the coal. After the shape of the raised film is recovered, an extending film distributed around the raised film in an annular array mode is extruded to expand by means of the liquidity of heat conduction fluid. Moreover, the raised film adapts to the coal particles after being turned over and elastically deforms along gaps among the coal particles to be in full contact and fit with the coal particles, and the absorbed heat is evenly and and fully released to the coal particles. Compared with an existing roller drying mode, the raised type coal particle environment-friendly drying equipment has the advantage that the coal particles can be rapidly and efficiently dried on the premise that the high yield is guaranteed.

Description

technical field [0001] The invention relates to the technical field of coal drying, and more specifically relates to a raised coal particle environmental protection drying equipment. Background technique [0002] The coal drying process refers to a special technical measure for coking coal preparation that pre-dries the furnace coal to reduce the moisture content to less than 6% and then loads it into the furnace. It has the functions of stabilizing the operation of the coke oven, improving the mechanical strength of the binder and reducing the heat consumption of coking. [0003] The current drying method is mainly the way of heating and drying. Through the transfer of heat, the hot air is urged to take away the evaporated moisture in the coal. Instead, the drying carrier used is usually a drum. During the rotation of the drum, through The inner wall of the drum transfers heat to the coal, and at the same time, the rolling drum can turn the coal, so that the coal can be co...

Problems solved by technology

[0004] However, during the current rolling process of the coal by the roller, the coal is still piled up at the bottom under the influence of gravity, and the lifting height of the coal turning process is limited, and the turning range is small, especially when the humidity is high, the coal sticks together , the lower lifting height of coal will affect the drying effect, and the larger turning range can improve the drying effect of coal, but it will easily lead to coal fragmentation
