Embodiment 1

[0011] A method for improving the process of burning coking coal by using a rotary kiln:

[0012] (1) Install a high-temperature secondary fan, and control the air temperature at 960 degrees Celsius.

[0013] (2) Improvement of the temperature monitoring technology in the calcination zone: open the kiln platform, use the pan-tilt to move the thermometer, and then realize the scanning of the temperature of the indoor materials.

[0014] (3) Improvement of the dust removal system technology: the height of the dust removal room is increased by 25m, and a natural supplementary air duct and an arched smoke removal wall are added, and the performance of the dust collector is modified through modern technology to enhance the dust removal ability of the dust collector.

[0015] (4) The ratio of coking coal at the head and tail kilns is 3.5:6.5.

Embodiment 2

[0017] A method for improving the process of burning coking coal by using a rotary kiln:

[0018] (1) Install a high-temperature secondary fan, and control the air temperature at 1000 degrees Celsius.

[0019] (2) Improvement of the temperature monitoring technology in the calcination zone: open the kiln platform, use the pan-tilt to move the thermometer, and then realize the scanning of the temperature of the indoor materials.

[0020] (3) Improvement of the dust removal system technology: the height of the dust removal room is increased by 25m, and a natural supplementary air duct and an arched smoke removal wall are added, and the performance of the dust collector is modified through modern technology to enhance the dust removal ability of the dust collector.

[0021] (4) The ratio of coking coal at the head and tail kilns is 3.5:6.5.

Abstract

The invention discloses an improved method of a process for burning coking coal by using a rotary kiln. The method comprises the following steps: (1) additionally installing a high-temperature secondary air fan; (2) improving a related temperature monitoring technology of a burning zone; and (3) improving a dedusting system technology. Through improvement of the process for burning coking coal by using the rotary kiln, high-efficiency, low-consumption and high-quality burning effect can be realized favorably, the petroleum coke resources are fully utilized, and a good environmental protection effect is obtained.

Description

technical field [0001] The invention relates to the field of industrial manufacturing, in particular to an improved method for burning coking coal by using a rotary kiln. Background technique [0002] At present, the process technology of using rotary kiln to burn coking coal has been widely used in China, but the technical level is average, and the automation level of the operation process is not high. During the calcination process of coking coal, the staff often operate only by experience, resulting in low production stability, insufficient production indicators, and high production costs. Therefore, it is very necessary to transform the existing process technology and related problems, which is conducive to achieving high-efficiency, low-consumption and high-quality calcination, and making full use of coking coal resources. Contents of the invention [0003] Therefore, the purpose of the present invention is to provide a more feasible scheme and idea, which is benefic...
