Coal briquette using coke tar slag and dust ash as raw materials as well as method for making same

Abstract

Disclosed are a briquette produced from raw materials of tar residue and precipitator dust, and method for making the same, wherein the proportion of raw materials by weight is tar residue 20%-40%; precipitator 80%-60%. The mentioned materials are agitated by double-shaft spiral agitator after mixed according to weight percentage, then are extrusion molded by forming machine, and it can be used as coking coal. The invention reuses waste produced in production process of coke-oven plant in the same enterprises. The invention realizes that wastes is not discharged out of the plant, thoroughly solves problems that bothers coke-oven plant for years, changes waste into valuables, cuts production cost, and enhances economic benefit.

Description

Technical field: [0001] The invention relates to a molded coal with tar residue and dedusted ash as raw materials and a production method thereof. Background technique: [0002] Tar residue and dust removal ash are wastes produced in the coking process. With the development of industrial production, more and more tar residue and dust removal dust are produced. The particle size of dust removal dust is small and hydrophobic, so it is difficult to process. It is also very easy to float with the wind, which not only causes great pollution to the surrounding environment, but also affects the development of enterprises. In order to solve the above problems, some enterprises mix a small amount of tar slag into coking coal and burn it for coking after mixing. However, because the tar slag is viscous, it is easy to stick during the preparation and mixing process, which pollutes the working environment and does not meet the requirements. According to the requirements of modern enter...

[0002] Tar residue and dust removal ash are wastes produced in the coking process. With the development of industrial production, more and more tar residue and dust removal dust are produced. The particle size of dust removal dust is small and hydrophobic, so it is difficult to process. It is also very easy to float with the wind, which not only causes great pollution to the surrounding environment, but also affects the development of enterprises

In order to solve the above problems, some enterprises mix a small amount of tar slag into coking coal and burn it for coking after mixing. However, because the tar slag is viscous, it is easy to stick during the preparation and mixing process, which pollutes the working environment and does not meet the requirements. According to the requirements of modern enterprises, gasoline and chemical raw materials can be extracted from tar residue, but the investment in equipment is relatively large. So far, the treatment of tar residue has always been an urgent problem to be solved by various coking enterprises
