Application of coal modifier in shaft kiln incineration and producing technique thereof

Abstract

A 'SHENZHOUSHENGLONG' coal modifier mainly consists of a grinding aid, a catalyst, an oxidant, a smoke suppressor and combustion improver, a smoke suppressor and igniter, a sulfur fixation agent, a bulking agent, a penetrating agent, etc. The coal modifier is a powdery material and can be added into coal (at a ratio of 0.1% the actual coal weight) to improve the combustion temperature and the combustion speed of the coal, thus achieving catalytic combustion and improving the coal combustion effect as well as the coal utilization rate. Accordingly, the invention performs the functions of saving coal, substituting high-quality coal by poor-quality coal, improving the hourly output of cement clinker stage, improving the grade of cement clinker, fixing sulfur and reducing the discharge of harmful gases such as SO2 in the smoke, thus protecting environment and indeed achieving the green production of cement.

Description

technology field; [0001] The invention is applied to the shaft kiln cement raw materials in the cement industry to configure the coal modifier and the production process, which can help grinding, save energy, improve product quality and output, reduce environmental pollution and other effects. Background technique [0002] my country is the world's largest producer and consumer of cement, and coal is the energy source in cement production. At least 200 million tons of coal energy are consumed by the cement industry every year, accounting for 1 / 10 of the total annual coal mining. Coal is the main fuel for cement production in my country, and it is also one of the main indicators of raw fuel consumption in cement production. The quality of coal not only affects the output and quality of cement clinker calcination, but also relates to the cost of cement production. Due to different production process equipment , there are different technical requirements for the quality and typ...

Problems solved by technology

Some liquid combustion accelerants increase with the temperature during the grinding process of raw materials, and some organic solvents evaporate, losing the combustion-supporting effect; some solid combustion accelerants achieve the effect of saving coal, but seriously affect the quality of cement products and cause secondary pollution , seriously affecting the environment
