Device for high-humidity charging coking coal humidifying technology

Abstract

The invention discloses a device for a high-humidity charging coking coal humidifying technology. The device comprises a fluidized bed damping machine, wherein a first fluidized bed type built-in heat humidifying module and a second fluidized bed type built-in heat humidifying module are arranged in the fluidized bed damping machine in parallel; an air preheater and a first fluidized blower are sequentially connected in series outside the first fluidized bed type built-in heat humidifying module to form a first process loop; a second fluidized blower is connected in series outside the second fluidized bed type built-in heat humidifying module form a second process loop; and the first process loop is connected with the second process loop through an adjustable overflow plate. By virtue of a frame structure, the air preheater and the fluidized bed damping machine are in modularized combination; the installation and repairing convenience of the process device is ensured; a plurality of modules can be freely combined into a large process device according to the production requirements; normal production of the humidifying system can be ensured only by reserving a backup module; and the scale of backup equipment for an existing humidifying system is reduced.

Description

technical field [0001] The invention relates to the technical field of coking in the coking industry, in particular to a device used in the high-humidity furnace charging coking coal humidity control process. Background technique [0002] Coal humidity control process (CMC) refers to the process of "moisture control of coal for coking and charging furnace". It is developed on the basis of dry coal coking technology. , dehydration, to achieve the adjustment and control of coal moisture. According to the current coking process requirements, the moisture in coal is controlled at about 6%, so as to reduce the energy consumption of the coking process, ensure the stability of coke oven operation, improve the quality of coke or increase the weak The purpose of adding the amount of caking coal and reducing the amount of coking sewage. At the same time, the moisture content of the coking coal in the furnace is reduced, and the bulk density of the coal is increased, which correspondi...

AI Technical Summary

Problems solved by technology

There is also the use of coke oven flue gas as a heat carrier, but high-temperature flue gas needs to be transported for a long distance, the energy consumption of the high-temperature fan with large air volume and the heat loss of the flue gas are large, and the flue gas flow rate is limited, the heat capacity is low, and the adjustability is poor.

Secondly, many domestic independent coking enterprises use coke oven gas as the heat source for coke ovens, and the flue gas produced has a high moisture content. Therefore, the flue gas has a low moisture-carrying capacity, which affects the humidity control efficiency.

In addition to the problems of high energy consumption, low adjustment ability, large basic investment, high operating cost, complicated control and adjustment, and large amount of maintenance, the above schemes have problems

When the moisture content of the coal material is too high, many coal humidity control and drying devices will be affected, which will seriously affect the effect and efficiency of the coal humidity control process
