Example Embodiment

[0014] Such as Figure 1-Figure 5 As shown, the carbon black reactor includes a combustion chamber 1, a throat section 2, a reaction section 3, and a quench section 4, 5, and 6. The cross section 7 of the reactor throat section is six-petaled plum blossom. Figure 5 The arrow in indicates the flow direction of the feedstock oil. Through the improvement of the furnace structure, the circular cross-section of the throat pipe is changed to a unequal polygonal cross-section, and a row of six oil guns are uniformly arranged in the same axial direction. The throat section has a non-circular cross-section and a large amount of raw oil Spray into the throat section and form a non-circular spray pattern on the cross section of the throat section. The throat section generates a high-temperature air flow whose cross-section is actually consistent with the non-circular cross-section of the injection mode, so that the raw oil injection can cover the cross-section of the high-temperature ai...

Abstract

The invention provides a carbon black reaction furnace, and relates to a reaction furnace in the carbon black industry. The cross section of a throat section of the reaction furnace is polygonal and is shaped like a plum flower with six petals, bricks of the reaction furnace are arranged into a plurality of layers, and the layers are arranged crosswise. By means of the novel polygonal carbon black reaction furnace, carbon black with a stable narrow particle size range and high color intensity can be produced, so that the quality of the carbon black is largely improved. The novel polygonal carbon black reaction furnace has the advantages that the area of the cross section is covered to the maximum extent, the length of the flame of pyrolytic raw oil reaches the minimum value, the generation of invalid high-temperature gas is largely reduced, partial raw oil is prevented from being subject to an excessive pyrolytic reaction, and therefore the carbon black with narrow particle size distribution is obtained.

Description

technical field [0001] The invention relates to a reaction furnace for carbon black industry. Background technique [0002] The atomization of the raw material oil sprayed into the throat section of the reaction furnace is observed from the actual furnace to form a non-cylindrical spray pattern. And the cross-sectional area of ​​the reaction furnace we use at present is circular, therefore, the cross-sectional area of ​​the high-temperature air flow passing through the cylindrical throat section is also circular. Because a non-circular pattern formed by raw oil injection does not match the circular cross-sectional area of ​​the high-temperature gas flow, even after the raw material oil has been added, part of the high-temperature gas flow (called ineffective high-temperature gas) is still against the injection The raw oil does not work. Ineffective high-temperature gas has an adverse effect on the carbon black process. a. The flame length of the raw oil is increased, whic...
