Embodiment Construction

[0035] Below in conjunction with the accompanying drawings, the full boiling vibration propulsion type coal humidity control and classification process of the present invention will be further described in detail:

[0036] The full-boiling vibration-propelled coal humidity control and classification process of the present invention uses a coal humidity control classifier as the fluidization and humidity control equipment of coal materials, and utilizes the working principle of a vibrating fluidized bed and under the action of secondary air to make different particles Coal materials with small diameters are in different motion and humidity control states in the coal humidity control classifier: 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, and the vibrating distribution plate 22 vibrating Under the action of driving force, it flows toward the humidity-adjusting coal outlet...

Abstract

The invention relates to a full-boiling vibration propelled coal humidifying and grading process. In the process, flue gas of a coke oven is taken as a heat source, a coal humidifying and grading machine is taken as coal fluidizing and humidifying equipment, and integration of coal humidifying and coal grading is realized according to principle of a vibrated fluidized bed under the action of secondary air, wherein the coal humidifying and grading machine comprises a primary air inlet section, a secondary air inlet section and a vibration distribution plate; the primary air inlet section is arranged at the lower part of the vibration distribution plate, and region at the upper part of the vibration distribution plate is a deposition separation region; and the vibration distribution plate is a vibrated fluidized bed structure which is arranged in an inclined manner, the secondary air inlet section is arranged at the upper part of the vibration distribution plate, and an airflow outlet is arranged at the top part of a grading machine. In the process, waste flue gas of the coke oven is taken as a heat medium, and the characteristics that raw material coal has high heat and mass transfer efficiency under the condition of a full-boiling fluidized bed and has low heat and mass transfer efficiency under the condition of a fixed bed and a semi-boiling fluidized bed are utilized, thus uniform and high-efficiency humidifying of coal can be realized and high-efficiency grading of the coal can also be realized.

Description

technical field [0001] The invention relates to a new coal preparation technology, which provides the technology of uniform humidity adjustment and then graded pulverization for the raw coal before pulverization in the coking process. 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 th...
