Abstract
The invention provides a cracking grading utilization production process for preparing coal briquette from coal with a small particle size. The cracking grading utilization production process for preparing the coal briquette from the coal with the small particle size comprises the following steps: S1, preparing coal briquette by using a coal preparation system; S2, cracking the coal briquette of the coal preparation system by using a cracking system; and S3, screening a product cracked by the cracking system by using a clean coal screening system. The cracking grading utilization production process for preparing the coal briquette from the coal with the small particle size, which is provided by the invention, adopts techniques of powdered coal crushing, composite adhesive addition and pelletizing, coal resources are sufficiently utilized, systems of coal conveying, coal screening, crushing and coke screening are operated in a completely sealed manner, in coke screening treatment, powercan be generated through coal gas combustion, a dust collection system is mounted for preventing serious pollution and resource waste caused by conventional random emission of coal dust and coke dust, and a production site is subjected to complete hardening treatment, that underground water pollution can be avoided, and volatilization of harmful gases along with moisture can be prevented.
Description
technical field [0001] The invention relates to the field of coal cracking with small particle size, in particular to a production process for cracking, quality-separating, and utilization of coal with small particle size for preparing briquettes. Background technique [0002] Cracking, also known as cracking, refers to the process of thermal decomposition and condensation of organic compounds to produce products with different relative molecular masses. Cracking may also be called thermal cracking or pyrolysis. According to whether a catalyst is used, it can be divided into thermal cracking and catalytic cracking; according to the existing medium, it can be divided into hydrocracking, oxidative cracking, ammonia cracking and steam cracking. [0003] Raw coal is usually divided into small particle size coal and large particle size coal. The average diameter of small particle size coal is less than 10mm, and the average diameter of large particle size coal is 30-80mm. Small ...
