Problems solved by technology

[0002] At present, most of the humidity control devices for drying coking coal to prepare furnace coal use steam as the heat source, which not only requires high investment, but also has high operating costs for the device. Some coal humidity control devices use coke oven flue gas as the heat source. Because of its low heat transfer efficiency or changes in the initial particle size of the coal material, its effect needs to be improved

Abstract

The invention discloses a full-fluidized jet fluidized bed damping machine and a novel damping process using the damping machine in the preparation of charging coal, belong to the technical field of coking coal preprocessing of a coking plant. The damping machine comprises a shell arranged at the upper part, a machine body arranged at the lower part, a bed body which is arranged between the shell and the machine body and is respectively connected with the shell and the machine body, and a support used for fixing the shell, the bed body and the machine body, wherein the shell is provided with a feeding port and an exhaust gas discharger; the machine body comprises a plurality of independent air chambers, the air chambers are provided with thermal fluid delivery pipe interfaces; and the bed body is provided with a fluid distributor and a discharging port which is arranged at one end of the fluid distributor. The coking coal and the coke oven flue gas exchange heat directly in the damping machine, and the charging coal after the drying is transported to a coke oven coal tower for the production of coking. According to the invention, the heat exchange efficiency can be significantly enhanced, and the coal is fluidized in the damping machine without changing the size fraction and size distribution of the coal fed into the damping machine.

Description

technical field [0001] The invention mainly relates to the technical field of coking coal pretreatment in a coking plant, in particular to a full-boiling jet fluidized bed humidity control machine and a new humidity control process for preparing furnace coal by using the humidity control machine. Background technique [0002] At present, most of the humidity control devices for drying coking coal to prepare furnace coal use steam as the heat source, which not only requires high investment, but also has high operating costs for the device. Some coal humidity control devices use coke oven flue gas as the heat source. Because of its low heat transfer efficiency or changing the initial particle size of the coal material, its effect needs to be improved. Therefore, how to improve the heat transfer efficiency of the coal humidity control device using coke oven flue gas as the heat source, and ensure that the moisture content of the coal after drying reaches the set target value an...
