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 circulation type carbon black reacting furnace, which comprises a heating chamber and a reaction chamber. The reaction chamber comprises a first reacting furnace and a secondreacting furnace. The second reacting furnace is arranged on two sides of the first reacting furnace. The first reacting furnace and the second reacting furnace are communicated with each other. Theheating chamber is fixed on the front end of the second reacting furnace. The heating chamber is communicated with the second reacting furnace. A pressurizing-guiding device is fixedly arranged in thefirst reacting furnace. A first raw oil nozzle is also arranged in the first reacting furnace. The rear end of the first raw oil nozzle stretches out of the first reacting furnace. The rear end of the first reacting furnace is sealed. The circulation type carbon black reacting furnace has the advantages that the pressurizing-guiding device is arranged in the first reacting furnace and is capableof converging and pressurizing gas flows introduced into the first reacting furnace from two sides; the temperature of the first reacting furnace can be quickly raised, the air flow is large, and dueto the high temperature, the raw oil can be fully cracked to generate carbon black. Due to the air flow, the generated carbon black will not deposit on the inner surface of the reacting furnace, the frequency of manual cleaning of the reacting furnace is reduced, and the labor cost is reduced therefore.

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 ...
