Abstract
The utility model relates to a 40 thousand-ton hard carbon black reacting furnace throat pipe device, which comprises a chrome corundum layer, a castable layer, a shell, raw oil injection ports and a throat pipe, wherein the throat pipe is sequentially provided with the chrome corundum layer, the castable layer and the shell from inside to outside; a plurality of raw oil injection ports are uniformly arranged in a rear section of the throat pipe in the radial direction; an inner cavity of the throat pipe is formed by connecting a plurality of inwards bulged circular arcs; and each raw oil injection port stretches into one end of the throat pipe and is located at a bulge part of each circular arc of the inner cavity of the throat pipe. According to the 40 thousand tons hard carbon black reacting furnace throat pipe device, gaps which cannot be covered by mist shadow formed by oil drops after a raw oil gun injects oil are reduced, the resistance for hot air flow to pass through is increased, and the temperature field distribution of carbon black generation reaction is more uniform, so that the particle size of the generated carbon black is small, the aggregates are distributed uniformly, and the color intensity, the nitrogen adsorption specific surface area and the compression oil absorption vale of carbon black are high; and meanwhile, only one row of raw oil injection ports is arranged, and a throat pipe structure is simplified, so that the safety and the operability of the throat pipe are improved.
Description
Technical field
The utility model relates to a kind of production of carbon black equipment, relates in particular to a kind of 40,000 tons of hard(carbon)black Reaktionsofen trunnion devices.
Background technology
At present domestic 40,000 tons of hard wet granulation black reactors all amplify and get from 20,000 tons of hard(carbon)black Reaktionsofens; Its structure is generally by the combustion chamber, trunnion, and three parts such as reaction chamber are formed; Combustion chamber one end is provided with the fuel entrance; The other end connects trunnion, radially is provided with the raw oil entrance on the trunnion, the other end ligation chamber of trunnion.Its black reactor technological process is: fuel (coal tar or coal gas or Sweet natural gas) with the certain proportion air mixed, gets into combustion chamber perfect combustion; Produce the elevated temperature heat air-flow more than 2050 ℃; With the flow velocity more than the per second 300-450 rice, at a high speed through trunnion, raw oil sprays into trunnion from entrance high pressure radially; Raw oil gets into reaction chamber and generates carbon black under the effect of high temperature and high speed combustion gas flowing; The trunnion inwall of former 40,000 tons of hard lines is built by laying bricks or stones with chrome corundum brick, is built into circular endoporus, the two batches of oil guns in front and back, and front-seat 4-6, back row 6-10 is only.Front-seat oil gun use water-cooling jacket, in stretch, to fill up when trunnion section raw oil sprays into spray less than the slit that stays, owing to the trunnion internal diameter is bigger; Because the penetration coefficient of raw oil is not enough, the mist shadow face that has a hollow raw oil oil droplet cover not in the middle of being prone to form is referring to Fig. 1, at the center of trunnion passage in mist shadow mid-way; Because the raw oil droplet does not cover, resistance is little here, the temperature field skewness that therefore forms; The particle size carbon black skewness that generates, particle diameter is big, and structure is low.Trunnion inconvenient operation when using front-seat raw material oil gun simultaneously, poor stability.
Summary of the invention
The purpose of the utility model is to provide a kind of 40,000 tons of hard(carbon)black Reaktionsofen trunnion devices, and it has easy to operate, and is safe, improves the advantage of production of carbon black quality.
The utility model is realized like this; It comprises chromium corundum layer, the cast bed of material, shell, raw oil entrance, trunnion; It is characterized in that trunnion from inside to outside is provided with chromium corundum layer, the cast bed of material and shell successively, the back segment of trunnion radially evenly is placed with some raw oil entrances, and the inner chamber of trunnion is formed by connecting on some inwardly protruded circular arcs; Each raw oil entrance stretches into an end of trunnion, all is positioned at the high spot of said trunnion inner chamber circular arc.
The technique effect of the utility model is: after the utility model had reduced raw oil and sprays into trunnion, the space that the mist shadow that oil droplet forms has covered had not increased the resistance that hot gas flow passes through; Make the temperature field of soot formation reaction be more evenly distributed, thereby the particle size carbon black that generates is little, aggregate is evenly distributed; Sooty tinctorial strength, nitrogen adsorption specific surface area and compression oil-absorption(number) are high; Owing to have only row's raw oil entrance, simplify throat tubular construction simultaneously, improved trunnion security and operability.

Fig. 2 is the structural representation of the utility model.
Fig. 3 is the utility model A-A schematic cross-section.
Embodiment
Like Fig. 2, shown in 3, the utility model realizes that like this it comprises chromium corundum layer 1, the cast bed of material 2, shell 3, raw oil entrance 4, trunnion 5; Trunnion 5 from inside to outside is provided with chromium corundum layer 1, the cast bed of material 2 and shell 3 successively; The back segment of trunnion 5 radially evenly is placed with some raw oil entrances 4, and the inner chamber of trunnion 5 is formed by connecting on some inwardly protruded circular arcs, and each raw oil entrance 4 stretches into an end of trunnion 5; All be positioned at the high spot of said trunnion 5 inner chamber circular arcs; During use, the elevated temperature heat air-flow is at a high speed through trunnion 5, and raw oil sprays into the trunnion 5 from raw oil entrance 4 high pressure radially; Raw oil gets into reaction chamber and generates carbon black under the effect of high temperature and high speed combustion gas flowing; Owing to be formed by connecting at the circular arc of trunnion 5 inner chambers convexity; And raw oil entrance 4 stretches into an end of trunnion 5, all is positioned at the high spot of trunnion 5 inner chamber circular arcs, has so just reduced the distance of 4 of corresponding raw oil entrances; Correspondingly reduced the space that oil droplet forms after 4 oil spouts of raw oil entrance mist shadow has covered not; Thereby increased the resistance that hot gas flow passes through, and the uniform distribution of temperature field that makes the soot formation reaction, thus the particle size carbon black that generates is little; Aggregate is evenly distributed, and sooty tinctorial strength, nitrogen adsorption specific surface area and compression oil-absorption(number) are high.Because trunnion 5 structures have only row's raw oil entrance 4, simplified the structure of trunnion 5 simultaneously, easy to operate, improved security.
