Problems solved by technology

The use of a single heating source for heating makes the production capacity of the carbon black reaction furnace relatively low. When the production capacity needs to be increased, there will be insufficient cracking and the upper limit of the production capacity of the single reaction furnace.

Abstract

The invention discloses a circulating carbon black reaction furnace, which comprises a heating chamber and a reaction chamber. The reaction chamber includes a first reaction furnace and a second reaction furnace. The furnace is connected with the second reaction furnace, the front end of the second reaction furnace is fixed with a heating chamber, the heating chamber is connected with the second reaction furnace, the inside of the first reaction chamber is fixed with a pressurized flow guide device, and the There is also a first raw material oil nozzle inside, the rear end of the first raw material oil nozzle protrudes from the first reaction furnace, and the rear end of the first reaction furnace is sealed; the advantage is that a pressurized flow guide device is installed in the first reaction furnace, The setting of the pressurized diversion device can make the airflow entering the first reaction furnace from both sides converge and pressurize, so that the temperature of the first reaction furnace rises faster, the air flow is larger, and the high temperature can fully crack the raw material oil to generate carbon black. The air flow can reduce the deposition of carbon black produced on the inner wall of the reaction furnace, reduce the number of manual cleaning, and reduce labor costs.

Description

technical field [0001] The invention relates to the field of reaction furnaces, in particular to a circulation type 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 obtained from carbon-containing substances, such as raw material oil, such as coal, natural gas, oil, etc., after incomplete combustion or thermal decomposition. product. 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 ...
