Abstract

The invention discloses a production system and process of pigment carbon black with low impurity content and relates to the field of production of carbon black. The production system comprises a raw material supply device, a reaction device, pre-heating devices, a collection device, a granulation device and a storage and packaging device, wherein air, raw oil and fuel oil enter the reaction device from the respective pre-heating devices; carbon black flue gas passing through the reaction device is used for pre-heating the air and the raw oil and sequentially enters the collection device, the granulation device and the storage and packaging device to finish carbon black collection; in the production process, the raw oil passes through four paths of filtering devices in advance; before an additive is blended, the raw oil is pre-dissolved with water; quenched water needs to be purified; an ultrafine grinding device is arranged in the collection device; the content of non-carbon impurities in a production process is effectively reduced and the purity of the pigment carbon black is improved; advanced equipment and process technology are adopted so that the aim of reducing the content of the impurities in a carbon black finished product is realized.

Description

technical field [0001] The invention belongs to the technical field of pigment carbon black, and in particular relates to a production system of pigment carbon black with low impurity content and a production method thereof. Background technique [0002] Pigment carbon black contains non-carbon black by-product impurities, mainly non-carbon components such as granular impurities, water, solvent extracts and inorganic salts. By-product impurities are divided into two categories: carbonaceous impurities and non-carbonaceous impurities. [0003] Carbon impurities come from coke particles in the process of producing carbon black. There are four ways to form coke particles: 1) Some catalyst powders, other mineral particles and additive K2CO3 in raw oil are the core of coke particles; 2) When the carbonization reaches a certain level, the carbon film on the inner surface of the oil pipe will rupture automatically, and the flaky bright small carbon particles will enter the reactio...
