Problems solved by technology

Ineffective high temperature gas has adverse effects on the carbon black process
a. Increase the flame length of the raw material oil, causing excessive pyrolysis of part of the raw material oil, and widen the particle size distribution of the carbon black product; b. Part of the invalid high-temperature air flow escapes without contact with the raw material oil. caused waste

Embodiment Construction

[0014] Such as Figure 1-Figure 5 As shown, the carbon black reaction furnace includes a combustion chamber 1, a throat section 2, a reaction section 3, and quenching sections 4, 5, and 6. The cross-section 7 of the throat section of the reactor is in the shape of a six-petal quincunx. Figure 5 The arrows in indicate the flow direction of raw oil. Through the improvement of the furnace structure, the circular cross-section of the throat is changed to an unequal polygonal cross-section, and a row of six oil guns is evenly arranged in the same axis. Spray into the throat section and form a non-circular spray pattern in the cross section of the throat section. The throat section produces a high-temperature gas flow whose cross-section is substantially consistent with the non-circular cross-section of the injection pattern, so as to maximize the coverage of the high-temperature gas flow cross-section by the feed oil injection.

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...
