Mixed carbon black reaction furnace

Abstract

The invention discloses a mixed carbon black reaction furnace. The mixed carbon black reaction furnace comprises a combustion chamber, a reaction chamber and a quenching chamber, the reaction chambercomprises a first reaction section and a second reaction section, the combustion chamber is fixed to the front end of the first reaction section, the front end of the second reaction section is fixedly matched with the rear end part of the first reaction section, the rear end of the second reaction section is fixedly matched with the quenching chamber, the first reaction section is provided with aplurality of first raw material nozzles which are uniformly distributed around the axis, the second reaction section is provided with at least one second raw material nozzle group, and the second rawmaterial nozzle group consists of a plurality of second raw material nozzles which are uniformly distributed around the axis of the second reaction section. The second reaction section is nested andmatched with the first reaction section and the quenching chamber, different distances from the second raw material nozzles to a fuel nozzle can be realized by adjusting the position of the second reaction section in order to change the temperature of the second raw material nozzles, and the particle sizes of the carbon black generated by cracking the raw oil are different due to different temperatures, so the carbon black with different particle sizes and controllable proportion is generated in the same reaction furnace.

Description

Technical field [0001] The invention relates to a carbon black reactor, in particular to a mixed type carbon black reactor. Background technique [0002] Carbon black is a kind of carbon with no fixed shape, light in weight and extremely fine black powder. Carbon black is a product of carbon-containing substances, such as coal, natural gas, and crude oil after incomplete combustion or thermal decomposition. Carbon black has a wide range of applications, such as black fuel, ink, graphite, and as an additive added to rubber and other materials to enhance the wear resistance and anti-aging properties of the material. Carbon black production processes include gas black production, channel black production and furnace black production. Gas black production mainly uses hydrocarbons as the main raw material, channel black production mainly uses natural gas as the raw material, and furnace black mainly uses oil as the raw material. [0003] The existing furnace black production process ma...

Problems solved by technology

At the same time, the existing nozzles used to spray raw material oil into the reaction furnace will cause the production efficiency of the reaction furnace to decrease after being blocked. In severe cases, it is necessary to stop the work and replace the nozzles in the reaction furnace. While improving the production efficiency of the factory, it needs to be debugged to check whether the produced carbon black meets the requirements when restarting the production, resulting in an increase in the production cost of the factory
