A kind of surface coal resource utilization device and its process

Abstract

The present invention relates to the field of resource utilization of flour coal, specifically a device for resource utilization of flour coal and its technology, including a furnace body, which is provided with a coal loosening mechanism and a lifting mechanism, and the coal loosening mechanism is driven by a first motor Do rotation and push-pull movement, so that the surface coal in the carbonization chamber is in full contact with the partition wall of the combustion chamber, and is evenly heated, preventing excessive carbonization caused by part of the surface coal being always too close to the partition wall of the combustion chamber, resulting in waste of resources, and at the same time preventing The surface coal is over-hardened during coking, which increases its air permeability, helps the gas generated during the coking of the surface coal to discharge, reduces the chamber pressure in the furnace body, and can handle the surface coal with an average particle size below 6mm; the second motor drives the lifting mechanism to rotate, When the third rotating shaft rotates, the lifting plate on its surface drives the coal on both sides of the furnace body to move upward from the bottom. As the reaction progresses, the coal in the carbonization mechanism and the lifting mechanism circulate each other, so that the coal in the furnace body is all Can be heated evenly.

Description

technical field [0001] The invention relates to the field of resource utilization of flour coal, in particular to a device for resource utilization of flour coal and a process thereof. Background technique [0002] Flour coal is pulverized coal, which refers to coal with a particle size of less than 6mm; with the improvement of fully mechanized mining and the increase in the proportion of subgroup coal mining, the content of pulverized coal continues to increase, and in addition to long-distance transportation, a considerable part of the raw coal that reaches users is pulverized coal. [0003] There are solid heat carrier and gas heat carrier as the heating medium for pulverized coal pyrolysis, but both methods have certain defects. For example, the solid heat carrier uses ceramic blocks as the heat carrier to heat the surface coal, and the ceramic block needs to be removed when the surface coal reaction is completed. blocks, making the processing steps more cumbersome; usi...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the problems in the prior art, the present invention provides a surface coal resource utilization device and its process, which solves the problem that for pulverized coal with a diameter of less than 6mm, the furnace pressure is too high due to the poor air permeability of the material layer, resulting in failure to coke and surface coal. Coal should also be heated evenly during carbonization to prevent excessive carbonization of some surface coal, resulting in waste of resources, and the coal located far away from the heat source on the edge of the coking furnace receives less heat, and often suffers from insufficient heating, which affects the quality of the finished product.
