Technical field
The invention belongs to the rubber grade carbon black technical field, is tire tread carbon black plant technical field furtherly, relates in particular to the Reaktionsofen of producing N100, N200, N300 series carbon black.
Background technology
The black reactor that is applied in all devices in the carbon black manufacturing processed, particularly production of carbon black is the nucleus equipment of carbon black production device.
Black reactor is that a kind of temperature of reaction is high, heat load intensity is large, one of the reactor of severe reaction conditions in the chemical industry technical field.Almost the major progress each time of carbon black production technology all relates to the improvement of carbon black reactor directly or indirectly.
The experimental study of carbon black reactor and to design and develop be to improve carbon black list furnace output and efficient, raising reactor hot strength is strengthened the soot formation reaction for ultimate aim.
Common carbon black is the carbon black that adopts oven process to make, and is divided into tyre surface carbon black and carcass carbon black, is called again inside industry: hard (carbon) black and soft carbon, and oven process tyre surface carbon black manufacture method generally has two kinds.
A kind of is regardless of oil fuel and stock oil, is axially entered by black reactor.Oil plant part fuel combustion under the effect of process (combustion-supporting) air provides the hot kinetic energy of remainder oil-cracking, generates the mixture of carbon black and flue gas.
Another kind be oil fuel (gas) in the perfect combustion of black reactor burning zone, the hot kinetic energy of the oil breaking of supplying raw materials radially injects stock oil atomizing in the trunnion section and mixes, and generates the mixture of carbon black and flue gas in the conversion zone cracking.
Above-mentioned two kinds of methods, the mixture of carbon black and flue gas are all stopped the carbon black reaction at quench zone by quenched water.
Furnace treated black production has been experienced double teacher so far: first-generation carbon black reactor: single chamber/pair chamber black reactor; S-generation carbon black reactor: new process carbon black Reaktionsofen; Third generation carbon black reactor: the black reactor of low hysteresis carbon black; The 4th generation carbon black reactor: maximization new process carbon black Reaktionsofen; The 5th generation carbon black reactor: nano carbon black/heterogeneous black reactor.

And because the Reaktionsofen size increases, the problem that the quality product of bringing descends can't overcome, therefore, and for the general many stoves parallel connections of adopting of enhancing production capacities.Be a plurality of black reactors after Reaktionsofen or in parallel after air preheater, what also have is in parallel before entering main bag filter.So both the increasing device floor space, increased again plant investment, reduced economic benefit.No matter be the production technique that increases the size of black reactor or adopt black reactor in parallel, up to now, the structure of black reactor is the single throat tubular construction form of a trunnion of a Reaktionsofen always.
In order to change this state, the present inventor has done a large amount of research and test, has proposed goal of the invention of the present invention.
Summary of the invention
