Description

Technical field[0001]The invention relates to the field of carbon black production, in particular to an air-cooled high-temperature alloy carbon black reaction furnace and a carbon black preparation method.Background technique[0002]Carbon black is a product obtained by incomplete combustion or thermal decomposition of carbonaceous substances (coal, natural gas, heavy oil, fuel oil, etc.) under conditions of insufficient air. It can be used as a black dye and a reinforcing agent for rubber. The carbon black reactor is a high-temperature device for the production of carbon black. The combustion chamber is the core equipment for carbon black production. The combustion chamber of the traditional carbon black reactor is a steel furnace shell with refractory bricks stacked to achieve a resistance of 2000 The effect of high temperature gas above ℃. The combustion chamber of the carbon black reactor needs to be mixed and combusted with gaseous fuel and air first, and then enter the throat s...
