Embodiment Construction

[0036] The full-boiling vibration-propelled coal humidity control and classification integrated equipment of the present invention will be further described in detail in conjunction with the accompanying drawings:

[0037] The present invention adopts the coal humidity control classifier as the coal material fluidization and humidity control equipment, utilizes the working principle of the vibrating fluidized bed and under the action of the secondary air, makes the coal materials with different particle sizes in the coal humidity control classifier In different states of movement and humidity control: Large particle coal materials are distributed under the fluidized layer to form a fixed bed or a fluidized bed with a relatively low fluidization height. The coal humidity control classifier flows in the direction of the humidity control coal outlet 29, and finally flows out from the humidity control coal outlet 29, and the fine particle coal material in the full boiling fluidizat...

Abstract

The invention relates to full-boiling vibration propelled coal moisture control and grading integrated equipment, which comprises a primary air inlet section, a secondary air inlet section, and a vibration distribution plate, wherein the primary air inlet section is positioned below the vibration distribution plate, and a sedimentation separation area is positioned in an area above the vibration distribution plate; the vibration distribution plate has an obliquely arranged fluidized bed structure; the top airflow outlet of a grader is connected with a fine particle separation device; the outlet of the fine particle separation device is connected with the inlet of a fine particle recycling device; the upper part of the fine particle recycling device is communicated with a smoke exhaust fanthrough a connecting pipeline; and the smoke exhaust fan is connected with a chimney. Coke oven flue gas is taken as a heat medium; and according to a characteristic that raw material coal has high heat and mass transfer efficiency in a full-boiling fluidized state and low heat and mass transfer efficiency in a fixed bed and half-boiling fluidized state, a coal material can be subjected to moisture control uniformly and efficiently, and can be efficiently graded.

Description

technical field [0001] The invention relates to a new type of coal preparation equipment, which provides equipment for uniform humidity adjustment and then graded pulverization for raw coal before coking process pulverization. Background technique [0002] 1. Coal humidity control technology [0003] At present, the industrialized coal humidity control technology in the world can be roughly divided into three generations according to its development history: the first generation coal humidity control technology uses heat transfer oil to recover the waste heat of the coke oven flue gas and the sensible heat of the coke oven riser pipe, and In the rotary dryer, heat conduction oil is used to indirectly heat the coal material, so that the coal material is dried and adjusted in humidity. The second-generation coal humidity control technology uses steam as the heat carrier. In the multi-tube rotary dryer, the steam is used to indirectly heat the coal material, so that the coal m...
