Problems solved by technology

[0002] At present, the production of furnace carbon black uses natural gas, coal gas, and liquid hydrocarbon oil as fuel, and the heat energy generated by combustion is used as the basic energy for cracking raw material oil into carbon black. The biggest disadvantage of this method is that when natural gas, coal gas, and liquid hydrocarbon oil are used as fuels for combustion, a large amount of air must be prepared to support combustion. Only 21% of the oxygen in the combustion-supporting air really plays a combustion-supporting role, and 79% of nitrogen has been used since entering the production system. It is consuming energy and has a negative effect. Some companies are also studying the use of oxygen-enriched combustion technology for carbon black production, so as to reduce the energy consumption of carbon black production, which has a certain effect, but the effect is not obvious

Abstract

The invention discloses a carbon black reaction furnace and a carbon black production method. A spray gun for injecting hydrocarbon gas flow is arranged at the upper end of a furnace body in the reaction furnace; a carbon black outlet is formed at the lower end of the furnace body in the reaction furnace; an electric-arc nuclear zone is formed on the middle section of the furnace body; a plasma generator is arranged on the side surface of the electric-arc nuclear zone; and the plasma generator is used for generating electric-arc nuclear, which is formed by air plasma, at the center of the electric-arc nuclear zone. The carbon black production method is used for increasing the carbon black chemical reaction speed, improving the reaction yield, changing the reaction process and initiating new chemical reaction by adopting a plasma ultrahigh-temperature combustion technology, so that the carbon black microcrystal generation process is interfered and the surface roughness of the carbon black nanometer dimension is improved to obtain the carbon black product with the nanometer structure.

Description

technical field [0001] The invention relates to a carbon black reaction furnace and a carbon black production method, which are mainly used for obtaining nano-structured carbon black products. Background technique [0002] At present, the production of furnace carbon black uses natural gas, coal gas, and liquid hydrocarbon oil as fuel, and the heat energy generated by combustion is used as the basic energy for cracking raw material oil into carbon black. The biggest disadvantage of this method is that natural gas, coal gas, and liquid hydrocarbon oil are used as fuel. When the fuel is burned, a large amount of air must be prepared to support combustion. Only 21% of the oxygen in the combustion-supporting air really plays a combustion-supporting role, and 79% of the nitrogen has been consuming energy since it entered the production system and has a negative effect. Some companies are also researching and adopting it. Oxygen-enriched combustion technology is used to produce ca...
