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

Novel Polygons black reactor

Technical field

The present invention relates to a kind of Reaktionsofen of carbon black industry.

Background technology

The stock oil atomizing situation that Reaktionsofen trunnion section sprays into, observing its formed shape from actual furnace is the spray pattern of a non-cylindrical.And the Reaktionsofen sectional area that we use at present is circular, and therefore, the high temperature gas flow sectional area by round shape trunnion section also is circular.Because spray forming a kind of non-circular pattern and the rounded section of high temperature gas flow by stock oil amasss and is not complementary, even so after adding stock oil, the high temperature gas flow (being referred to as invalid high-temperature gas) of part is still inoperative to the stock oil that sprays into.Invalid high-temperature gas has adverse influence to carbon black process.A, increased the length of flame of stock oil, made the part material fry dried food ingredients give birth to excessive pyrolysis, the particle size distribution of having widened carbon black products; B, a part of invalid high temperature gas flow have just escaped in situation about not coming in contact with stock oil, have caused wasting phenomenon.

Summary of the invention

The invention provides a kind of trunnion section and produce in fact consistent with the non-circular cross sections of the jet mode high temperature gas flow of a kind of cross section, with and in making the stock oil ejecta cover to greatest extent the Polygons black reactor of the cross section of high temperature gas flow.

The present invention is achieved by the following technical solution: a kind of new-type carbon black Reaktionsofen, its technical characteristics are that described Reaktionsofen trunnion section cross section is Polygons;

As preferably, described Reaktionsofen trunnion section cross section is that six lobes are quincunx;

The fragment of brick of described Reaktionsofen is arranged as some layers, every layer of arranged crosswise.

The present invention can produce to have by this stove and stablize narrow particle size range and high tinctorial strength carbon black, and carbon black mass is increased substantially.Advantage: 1, cover to greatest extent cross-sectional area, the length of flame of the stock oil of pyrolysis has just reached minimum value.2, greatly dwindled the generation of invalid high-temperature gas, avoided the part material fry dried food ingredients to give birth to excessive pyrolytic reaction, thereby obtained having narrow particle size distribution.

Embodiment:

Such as Fig. 1-shown in Figure 5, this black reactor comprises combustion chamber 1, trunnion section 2, conversion zone 3, quench zone 4,5,6.Reaktionsofen trunnion section cross section 7 is that six lobes are quincunx.Arrow among Fig. 5 represents the flow direction of stock oil.Improve by furnace type structure, make the trunnion circular cross section into scalene Polygons cross section, adopt same axially, be evenly arranged six oil guns of a row, the trunnion section has a non-circular cross sections, sprays into the trunnion section and has formed a non-circular jet mode at trunnion section cross section with a large amount of stock oils.The trunnion section produces in fact consistent with the non-circular cross sections of the jet mode high temperature gas flow of a kind of cross section, with and in making the stock oil ejecta cover to greatest extent the cross section of high temperature gas flow.

Such as Fig. 6, shown in Figure 7, for cooperating scalene Polygons cross section Reaktionsofen, the fragment of brick 8 of Reaktionsofen trunnion section is arranged as some layers, every layer of arranged crosswise.
