Abstract
The utility model discloses a hard carbon black reaction furnace applicable to a coal tar material, and the hard carbon black reaction furnace is used for improving the yield and quality of special carbon black. The hard carbon black reaction furnace comprises a combustion segment, a contraction segment, a venturi segment and a reaction segment, wherein the rear end of the combustion segment is connected with the contraction segment; the front end of the combustion segment is provided with an additive inlet, an air inlet, a fuel oil inlet, a coke oven gas inlet and a natural gas inlet; the front end of the venturi segment is connected with the contraction segment, while the rear end of the venturi segment is connected with the reaction segment; the venturi segment is provided with a raw oil inlet; and the reaction segment is provided with a quenched water inlet.
Description
Technical field
The utility model relates to a kind of hard(carbon)black Reaktionsofen of suitable coals tar stock.
Background technology
The employed black reactor of China present production of carbon black producer, majority are the Reaktionsofen of introducing from the U.S..It is that raw material is produced carbon black products that this stove mainly adopts acetylene tar; Along with the day of acetylene, ethylene bottom oil is becoming tight; Occurred directly to adopt coal tar to produce the Reaktionsofen of hard(carbon)black, but there be the difference of raw oil rerum natura, the problems such as poor operability of being regardless of in this stove.Through the adjusting of processing parameter, can adapt to general soft/hard carbon black production, only can satisfy the demand of the smaller production of carbon black producer of some scales at present.
Summary of the invention
The utility model purpose is exactly the deficiency that overcomes above-mentioned prior art, and a kind of hard(carbon)black Reaktionsofen that improves the suitable coals tar stock of black carbon special output and quality is provided.
The utility model comprises burning zone, contraction section, trunnion section and conversion zone; The burning zone rear end is connected with contraction section, contraction section cone inclination angle theta
1 =50 °, contraction section cone inclination angle becomes air and the full combustion of fuel combustion that helps greatly spraying in the stove.The burning zone front end is provided with additive inlet port, air, oil fuel import, coke-oven gas import and Sweet natural gas import, and air, Sweet natural gas, oil fuel, four in coke-oven gas are uniformly distributed with from burning zone and spray into, for production of carbon black provides heat; Additive sprays in the combustion chamber, is used to adjust the carbon black products structure.Trunnion section front end is connected with contraction section, and the rear end is connected with conversion zone; The trunnion section is provided with the raw oil import, and conversion zone is provided with the quenched water import, and quenched water can spray in the Reaktionsofen from conversion zone, stops the carbon black reaction.
The utility model shortens cone length through strengthening, increase combustion chamber internal diameter and length, increases the cone inclination angle; Let and spray into air and the full combustion of fuel combustion in the stove; Increasing the turbulent extent of combustion product gases, the raw oil thorough mixing that sprays into trunnion is in utmost point cracking in the short period of time; Make the particle size carbon black distribution narrow, thereby improve sooty output and quality.Last effect is good, production is stable, and output improves, and ton hard(carbon)black consumption oil reduces, and tinctorial strength increases progressively.Can improve the output and the quality of black carbon special.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure:1, additive inlet port, 2, air, 3, the oil fuel import, 4, burning zone, 5, contraction section, 6, the trunnion section, 7, conversion zone, 8, the quenched water import, 9, the raw oil import, 10, the cone angle, 11, the coke-oven gas import, 12, the Sweet natural gas import.
Specific embodiments
At air 2 places; Air after the preheating is mixed mutually with fuel, atomizing medium from oil fuel import 3, coke-oven gas import 11 and Sweet natural gas import 12, regulates through the design at awl square and cone inclination angle, sprays into burning in the burning zone 4; Produce 1920 ℃～2000 ℃ high-temperature flue gas; Behind the raw oil thorough mixing that sprays into the 6 raw oil imports 9 of trunnion section, get into conversion zone 7 cracking and generate carbon black, the quenched water termination reaction that sprays into through quenched water import 8 again.On conversion zone 7, be provided with four row's quenched water imports 8, can be according to different positions, the adjustment quality product.
The inner diameter d of burning zone 4
1Be 860mm, length L
1Be 1850mm; The cone length D of contraction section 5
1Be 918mm, the cone inclination angle theta
1 =50 °It is big that the cone inclination angle becomes, and makes the turbulent velocity of combustion product gases become big, and the raw oil contact cracking time that radially sprays into trunnion shortens, and the particle size carbon black distribution narrow improves output and quality.
Claims (2)
1. the hard(carbon)black Reaktionsofen of a suitable coals tar stock is characterized in that comprising burning zone, contraction section, trunnion section and conversion zone; The burning zone rear end is connected with contraction section, and the burning zone front end is provided with additive inlet port, air, oil fuel import, coke-oven gas import and Sweet natural gas import; Trunnion section front end is connected with contraction section, and the rear end is connected with conversion zone; The trunnion section is provided with the raw oil import, and conversion zone is provided with the quenched water import.
