Low-energy-consumption high-pigment carbon black production method and production equipment thereof

Abstract

The invention discloses a low-energy-consumption high-pigment carbon black production method and production equipment thereof, and relates to the field of high-pigment carbon black production; the low-energy-consumption high-pigment carbon black production equipment comprises an air rectifier, a combustion chamber, a throat, a reaction chamber, a vertical quenching section and an air preheater, acoal gas inlet is formed in one side of the air rectifier, and a hot air inlet is formed in the top of the air rectifier. Through the arrangement of a gathering barrel, through holes and a dispersionnet, after materials enter the reaction chamber, the materials can move in the reaction chamber in the direction perpendicular to the quenching section; in the process, the materials can move along the gathering barrel, the materials move in the direction of the through holes through the gathering barrel and are concentrated, so that the materials are more mixed; and then the materials are dispersed through the through holes and penetrate through the dispersing net, the gathered materials are dispersed again, through the moving mode, the contact area between the materials can be wider throughmultiple times of dispersing and gathering of the materials, mixing can be more uniform, and the situation that the materials are mixed and react unevenly is avoided.

Description

technical field [0001] The invention relates to the field of high-pigment carbon black production, in particular to a low-energy production method and production equipment for high-pigment carbon black. Background technique [0002] Pigment carbon black is mainly used for coloring or color matching. Internationally, according to the coloring ability of carbon black, it is usually divided into three categories, namely, high-pigment carbon black, medium-pigment carbon black and low-pigment carbon black. This classification is usually represented by three English letters, and the first two letters represent carbon black. The coloring ability, the last letter indicates the production method. The commonly used dosage forms are powder and granular, high-pigment carbon black, used in coatings and plastics, has good blackness, good dispersibility, medium-pigment carbon black is used in coatings, plastics, blue phase, good tinting strength; used in inks , coatings, excellent disper...
