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

Abstract

The invention discloses a hybrid carbon black reaction furnace, which includes a combustion chamber, a reaction chamber and a quenching chamber. The reaction chamber includes 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 reaction section is fixedly matched with the rear end of the first reaction section, and the rear end of the second reaction section is fixedly matched with the quench chamber. The first reaction section is provided with a plurality of first raw material nozzles evenly distributed around the axis, and the second reaction The section is provided with at least one group of second raw material nozzle groups, and the second raw material nozzle group consists of a plurality of second raw material nozzles evenly distributed around the axis of the second reaction section; Nesting fit, the distance between the second raw material nozzle and the fuel nozzle can be different by adjusting the position of the second reaction section, thereby changing the temperature at the second raw material nozzle, and the particle size of the carbon black produced by the cracking of the raw material oil is different when the temperature is different. Therefore, carbon black with different particle sizes and controllable ratio can be produced in the same reaction furnace.

Description

technical field [0001] The invention relates to a carbon black reaction furnace, in particular to a mixed carbon black reaction furnace. Background technique [0002] Carbon black is a kind of carbon with no fixed shape, light weight and extremely fine black powder. Carbon black is a product obtained by incomplete combustion or thermal decomposition of carbon-containing substances, such as coal, natural gas, and crude oil. Carbon black is widely used, such as in black fuel, ink, graphite, and as an additive added to rubber and other materials to enhance the wear resistance and anti-aging properties of materials. 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 raw material, and furnace black mainly uses oil as raw material. [0003] The existing furnace black production process is ma...
