Description

technical field

[0001] The invention relates to a carbon black production device, in particular to a device for producing carbon black by thermal cracking. Background technique

[0002] Thermal cracking method (also known as thermal cracking method) is a common method of carbon black production. It uses natural gas as raw material and produces carbon black through high temperature thermal cracking at 1000 to 1300 °C in the absence of oxygen and flame. The carbon black produced by this method has unique qualities and is widely used in rubber, machinery, metallurgy, plastics and other fields.

[0003] At present, the thermal cracking carbon black manufacturers in the world mainly include CANCARB LIMITED in Canada, EVONIC in the United States and GAZPROM in Russia. The typical equipment and process used to produce carbon black by this method are as follows: figure 1 As shown, the main supply fan 1 is connected with the cracking furnace A2 and the cracking furnace B3 respectiv...
