A process for preparing rock wool from coal gasification ash and slag pool structure

Abstract

The invention provides a process for preparing rock wool from coal gasification ash slag and a slag pool structure, which comprises the following steps: feeding coal water into a coal mill to prepare a coal water slurry, and under the action of a coal slurry pump, the coal slurry is It is passed into the gasifier together with the external oxygen; the syngas produced by the gasifier enters the cyclone separator; the high-temperature slag of unreactable minerals at the lower end of the gasifier, slag and unreacted The carbon flows down together in the same direction, and directly falls into the slag pool in liquid form; the slag in the slag pool is passed into the four-roller cotton machine, and the high-temperature ash is heated by plasma to prepare rock wool. The process for preparing rock wool from coal gasification slag and the structure of the slag pool provided by the patent of the present invention can maximize the benefits of coal gasification slag treatment and rock wool preparation, reduce labor costs, and improve the efficiency of production labor.

Description

technical field [0001] The invention belongs to the technical field of mineral wool preparation, in particular to a process for preparing rock wool from coal gasification ash and a slag pool structure. Background technique [0002] The characteristics of my country's rich coal, lean oil and little gas make coal still the main energy source in my country for a long time in the future. Oil technology has received great attention and development. However, this technology is also an important source of waste residue generation. According to statistics, the million-ton coal indirect oil-to-oil process will produce more than 900,000 tons of ash each year, mainly from coal gasification residues. and boiler ash, accounting for about 95% and 5% of the total slag production, respectively. [0003] As a by-product of coal chemical industry, gasifier ash and slag have high ash content, low calorific value, fine particle size, pile up and pollute the environment. At present, the treatmen...
