Bottom, described electric arc core district is provided with cooling water spray gun, by spraying into the water coolant termination reaction of lowering the temperature.
The angle of described spray gun spout makes the hydrocarbon stream tail dimension D1 of its generation less than the dimension D 2 of the electric arc core that forms, and makes aerosol as far as possible all contact high-temperature electric arc.
Described Reaktionsofen electric arc core district internal diameter size D3 is greater than electric arc core dimension D 2, the ultrahigh-temperature that guarantees electric arc core does not directly touch the Reaktionsofen inner bag, what contact with inner bag is only the carbon black that is cracked into after the hydrocarbon heat absorption, and ultrahigh-temperature electric arc core is wrapped in the carbon black air-flow all the time.
In addition, the present invention also provides a kind of method of producing black pigment, it is characterized in that comprising the following steps: in black reactor, hydrocarbon stream penetrates continuously through spray gun and forms the hydrocarbon stream aerosol, in the black reactor stage casing, the plasma body that is produced by plasma generator forms the localized hyperthermia district of 5000～8000K, and hydrocarbon stream is subject to high temperature action during by this district, and 10
-3Cracking rapidly in second, thus carbon black generated, the carbon black air-flow flows into the rear portion section of collecting, and the termination reaction of lowering the temperature under the water coolant effect that the water spray gun sprays into also flows out from the carbon black outlet.
The air flow power of carbon black is mainly to be provided by the hydrocarbon stream spray gun in described Reaktionsofen, is secondly the pressurized air that the plasma generator striking is used, and these power drive carbon black air-flows and enter the black reactor bottom.
Described plasma body is wrapped in the carbon black air-flow all the time.
The present invention adopts plasma technology ultrahigh-temperature cracking steam state hydrocarbon, accelerate the carbon black chemical reaction velocity, improve reaction yield, reduce energy consumption, change reaction process and cause new chemical reaction, carbon black crystallite formation reaction process is disturbed, improve the surfaceness of carbon black nano-scale, reduce the bonding force of the formation of aggregate, obtain the carbon black products of nanostructure.
