Production method of environment-friendly and safe furnace carbon black and carbon black product

Abstract

The invention discloses a production method of environment-friendly and safe furnace carbon black and a carbon black product. The production method comprises the following steps: preheating raw material oil after fractioning treatment, then spraying the preheated raw material oil into a furnace carbon black reaction furnace with an ultra-long retention section from a throat pipe section, and strictly controlling the purity of the raw material entering the furnace to prepare carbon black smoke gas; collecting the carbon black in the carbon black smoke gas by a main bag filter; crushing the carbon black by a micron crushing machine, then sending the carbon black to a collection cyclone separator and an exhaust bag filter by a wind-sending fan, exhausting waste gas, collecting carbon black powder to a carbon black storage tank, and meanwhile, introducing one part of preheated hot air to a conveying pipeline from the wind-sending fan to the collection cyclone separator; sending the powdery carbon black in the carbon black storage tank to at least one oxidation-granulation unit for oxidation and granulation; sending the prepared oxidized carbon black into a roller rotary drying machine for drying; and drying and packaging a finished product. The process disclosed by the invention is safe and reliable, and the produced pigment carbon black can meet various international environment-friendly and safe requirements of the carbon black products.

Description

technical field [0001] The invention relates to a method for producing environmentally safe furnace carbon black and a carbon black product thereof, belonging to the field of carbon black production. Background technique [0002] As a black pigment, carbon black is widely used in chalk, crayon, plasticine, paint, varnish, pen ink, liquid adhesive, glue, surface coating (paint, varnish, ink, etc.), plastic, rubber, silicone And other polymer materials, paper, cardboard materials, textile materials, glass, ceramics, metal materials, wood, fiberboard, bone, cortical materials, although the amount is not large, but carbon black as a raw material is added to it, becoming various One of the components of a product. [0003] With the progress of society, people are becoming more and more aware of environmental protection and life safety maintenance. Following this trend, standards such as IEC IEC 62321 of the International Electrotechnical Commission, AP (89) 1 test of the EU col...

Problems solved by technology

[0005] Since the main raw material of furnace carbon black comes from the leftovers of coal chemical industry or petrochemical industry, the composition of raw material oil is very complex and its quality is unstable. When carbon black is produced, hydrocarbons (solid, liquid or gaseous) are incompletely burned or cracked. Due to the difference in furnace temperature and quenching method, a small amount of liquid aromatic hydrocarbons will not be completely cracked, but will remain and adsorb on the surface of carbon black. Using new technology carbon black production technology to produce carbon black with larger particle size, the surface of carbon black is often There will be more residues and adsorbed substances, and these objective problems will bring difficulties to the production of high-quality carbon black products
