Device for high humidity charging coking coal humidity control process

Abstract

The invention discloses a device for high-humidity furnace-loading coking coal humidity control technology, which comprises a fluidized bed type humidity control machine, and a first fluidized bed type built-in heat control device is arranged side by side in the fluidized bed type humidity control machine. The humidity module and the second fluidized bed type built-in heat and humidity control module, the first fluidized bed type built-in heat and humidity control module is connected in series with an air preheater and a first fluidization fan in series to form a first process loop; The second fluidized bed type built-in heat and humidity control module is connected in series with a second fluidization fan to form a second process loop; the first process loop and the second process loop are connected through an adjustable overflow plate. The present invention adopts a frame structure, and the air preheater and the fluidized bed type humidifier are all modularized combinations, which ensures convenient installation and maintenance of the process device, and multiple modules can be arbitrarily combined into a large process device according to production requirements. Only one backup module is needed to ensure the normal production of the humidity control system, which reduces the scale of the backup equipment of the existing humidity control system.

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...
