Description
Technical field
The utility model relates to production of carbon black field, in particular to black reactor.
Background technology
Carbon black is that under the operating mode of stock oil (coal tar, carbolineum, ethylene bottom oil etc.) high temperature, high flow rate in Reaktionsofen, incomplete combustion generates.The oil-absorption(number) of carbon black is an important indicator weighing carbon black mass, and oil-absorption(number) is higher, and the quality of carbon black is higher.
At present, in production of carbon black, most widely used equipment is six segmentation Reaktionsofens, and this Reaktionsofen comprises burner, burning zone, trunnion section, conversion zone, cooling section and six parts of stay segment of connecting successively.The principle of work of this Reaktionsofen is: coal gas and air enter burning zone by burner, then in burning zone perfect combustion, produces high-temperature high-speed airflow, enters subsequently trunnion section; Now stock oil sprays into trunnion section through the oil gun of trunnion section setting, subsequently trunnion section with in conversion zone with from the high-temperature high-speed airflow of burning zone, contact mixing, stock oil rapidly vaporization cracking generates carbon black; Carbon black enters cooling section by cooling rapidly subsequently, then enters stay segment, for next process operations such as () granulation of carbon black, dry or collections is prepared.
In above-mentioned reaction, the reaction times of carbon black is longer, and chain branch structure is just longer, and oil-absorption(number) is also just higher.And oil gun is closely related to the distance of cooling section in the reaction times of carbon black and trunnion section, in trunnion section, oil gun is longer to the distance of cooling section, and the reaction times of carbon black is just longer, and the oil-absorption(number) of the carbon black of generation is also just higher.But the reaction times of carbon black is longer, the byproduct that stock oil generates is just more, and the output of carbon black decreases.For this reason, the black reactor in correlation technique adopts the trunnion section of following structure conventionally: an oil extraction rifle (being front-seat oil gun and rear oil extraction rifle) is set respectively at the two ends of trunnion section.Because the front end of trunnion section is connected with burning zone, rear end is connected with conversion zone, and therefore front-seat oil gun is far away apart from cooling section, makes the long reaction time of stock oil, and the oil-absorption(number) of the carbon black of generation is higher, but yields poorly.Rear oil extraction rifle is near apart from cooling section, makes the reaction times of stock oil short, and the carbon black output of generation is high, but oil-absorption(number) is lower, cannot meet quality product requirement.
As can be seen here, adopt the as above trunnion section of structure, although the ultimate production of carbon black increases.But the output of the carbon black of high oil-absorption(number) is still lower.
Utility model content
The purpose of this utility model is to provide black reactor, to solve the above problems.
A kind of black reactor is provided in embodiment of the present utility model, has comprised the burning zone, trunnion section, conversion zone and the cooling section that connect successively; Trunnion section is provided with front-seat oil gun and rear oil extraction rifle, and trunnion section goes forward to be provided with middle oil extraction rifle between oil extraction rifle and rear oil extraction rifle.
