Environment-friendly carbon black and production process thereof

Abstract

The invention discloses environment-friendly carbon black and a production process thereof, and relates to the technical field of carbon black production. Carbon black flue gas is subjected to cyclone separation through a cyclone separator of environment-friendly carbon black production equipment, so that high-temperature flue gas is effectively separated from carbon black, then the carbon black is conveyed to a material mixing mechanism to be evenly mixed with water and a binding agent to obtain acarbon black wet material, the carbon black wet material is conveyed to a forming mechanism, and granulated in the forming mechanism to form carbon black particles, and then the carbon black particles are dried by taking high-temperature flue gas as a heat source to obtain the environment-friendly carbon black. The environment-friendly carbon black is prepared from carbon black and the binding agent, and carbon black fine powder generated in the production process is agglomerated to form granular carbon black, so that the pollution to the environment caused by flying of the carbon black fine powder in the production and use processes is avoided; in addition, the carbon black production tail gas is firstly used as a heat source to dry carbon black particles before being purified in the high production process, so that heat is fully utilized, energy consumption is reduced, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of carbon black production, in particular to an environmentally friendly carbon black and a production process thereof. Background technique [0002] Carbon black is a light, loose and extremely fine black powder whose main component is amorphous carbon. It has a very large surface area. The resulting product (with greater adhesion). Carbon black has a wide range of applications. It can be used as a black dye to make Chinese ink, printing ink, paint, etc. It is also used as a reinforcing agent for rubber and plays an important role in the industrial field. [0003] However, carbon black is easy to fly with the wind during production, transportation and use, and enters the air to cause environmental pollution. [0004] Therefore, need badly a kind of environment-friendly carbon black and production technique thereof to solve the above problems. Contents of the invention [0005] In order to overcome the ...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the above-mentioned technical problems, the object of the present invention is to provide a kind of environmental protection carbon black and its production process: by using the cyclone separator of environmental protection carbon black production equipment, the carbon black flue gas is subjected to cyclone separation, thereby the high temperature flue gas and carbon The black is effectively separated, and then the carbon black is transported to the mixing mechanism to mix evenly with water and the binder to obtain a carbon black wet material, and then the carbon black wet material is transported to the forming mechanism, and the carbon black is first granulated in the forming mechanism to form carbon After that, the carbon black particles are dried with high-temperature flue gas as the heat source to obtain an environmentally friendly carbon black, which solves the problem that the existing carbon black is easy to fly with the wind during production, transportation and use, and enters the air to cause environmental pollution The problem
