Description

Technical Field

[0001] The utility model relates to the technical field of impurity removal equipment, in particular to a simple slag remover. Background Art

[0002] Carbon black, also known as carbon black, is a type of amorphous carbon. It is a light, loose and extremely fine black powder with a very large surface area. It is a product obtained by incomplete combustion or thermal decomposition of carbon-containing substances under insufficient air conditions.

[0003] In the process of carbon black production, there are several reasons why impurities are easily generated: 1. Refractory material falls off. The carbon black reactor has a temperature of 1900℃, and chrome corundum refractory material is required. During the start-up, shutdown and production process, some refractory material falls off and enters the carbon black product. 2. Rust and free carbon are contained in the raw oil. 3. Ca and Mg salt scaling in the quenching water. 4. Equipment corrosion. 5. Wear of rotating equipment. The requirements for high-quality carbon black are carbon black impurities ≤1000ppmn, pigment carbon black impurities ≤50ppmn, conductive carbon black impurities ≤20ppmn, and a few high-end products impurities ≤10ppmn, so it is very important to remove impurities in carbon black and improve the purity of carbon black.
