(2) described fuel and additive are sent into the combustion chamber of reacting furnace, the hot-air mixed combustion sent with above-mentioned distribution plenum, temperature controls at 1900 ~ 1927 DEG C.Described feedstock oil, after fuel oil preheating device is preheated to 180 ~ 260 DEG C, is sprayed into by the trunnion section of reacting furnace, through atomization, shears, carries out the cracking reaction of 6 ~ 20 microseconds at the conversion zone of reacting furnace, produce carbon black smoke;
(3) described carbon black smoke carries out a chilling at reacting furnace quench zone, more successively through air preheater and fuel oil preheating device, finally carries out secondary chilling, makes its temperature be down to 260 ~ 290 DEG C;
(4) carbon black smoke after cooling enters main bag hose and collects, and the carbon black of collection delivers to collection cyclone separator through wind pressure fan after micron disintegrator is pulverized;
(5) carbon black of described cyclone collection is through granulator granulation, makes the particle diameter of carbon black particle be 0.5-1.4mm, then drying machine is dry.
The most significant advantage of the present invention is: LX-LS200 carbon black products of the present invention; take natural gas as fuel; coal tar, carbolineum, miscella are mixed into feedstock oil with proper proportion, and the feedstock oil of employing is rational in infrastructure, and carbon yield is higher; produce the minimum and narrow distribution of carbon black products particle diameter; structure comparison is low, and powdery carbon black is obtained after micron disintegrator, comminutor, drying machine, mature preparation process; be applicable to industrialized production, there is significant economic benefit.
Carbon black products of the present invention (called after LX-LS200) belongs to medium super abrasion furnace black, has middle super abrasive, improves and collapse the advantages such as flower, breach performance, further improves the mixing shortcoming of not easily disperseing of middle super abrasive series carbon black simultaneously.About 7 grades can be reached through experimental analysis LX-LS200 carbon black particle dispersion grade point, and the N219 carbon black particle belonging to medium super abrasion furnace black together disperses grade point generally at about 6 grades, as can be seen from above-mentioned separate data, LX-LS200 is higher by 15% ~ 20% than common medium super abrasion furnace black dispersion grade point, namely improves the mixing shortcoming of not easily disperseing of middle super abrasive series carbon black to a certain extent.
