Abstract

The invention discloses a coal mixing method and apparatus suitable for a coal gasification apparatus, which belongs to the technical field of coal mixing processes in the field of large-sized coal chemical industry. By arranging a semi-closed circular cabin, a blanking opening is formed in the bottom of the cabin, and the blanking opening is provided with a blanking buffering cabin; the cabin collects materials by virtue of a material collection scraper machine, regulates and controls the current of the material collection scraper machine and controls a coal amount entering the buffering cabin from the cabin, a material level device is arranged on a 75 to 85 percent position of the level height in the buffering cabin, when the material level device touches a material, the material level device inclines; when the inclination angle is greater than 30 degrees, a switch is switched on, a current loop is generated to control the material collection scraper machine to be automatically stopped and to stop the collection of the material; and the blanking opening of the cabin is provided with the buffering cabin, the material level gauge, a control operation current interval and a buffering cabin material level monitoring system are arranged in the buffering cabin to realize the stability of the material level of the buffering cabin, a bidirectional coal feeding machine is controlled to transport and rotate so as to stably blank the raw material, thereby ensuring the stability of the mixed coal quality.

Description

technical field [0001] The invention relates to the technical field of coal blending technology in the field of large-scale coal chemical industry, in particular to a coal blending method and device suitable for a coal gasification device. Background technique [0002] Judging from the start-up and operation experience of Shell gasifiers in China, coal quality problems have always plagued major manufacturers. For a long time, the stability of blended coal quality has always been one of the problems that plague the blending quality of large-scale blended coal processes, and unplanned shutdowns or production accidents caused by unstable blended coal quality have also occurred frequently. For example, the inner wall of the gasifier was corroded due to coal quality problems in the early stage of coal chemical project commissioning. In the process of finding out the cause and taking measures, many detours were taken, resulting in huge losses. The biggest bottleneck in the operat...
