A carbon black waste gas treatment process

Abstract

The invention discloses a carbon black waste gas treatment process, comprising the following steps: S1, putting the mixture into a carbon black reaction furnace for reaction, and obtaining carbon black flue gas after the reaction; S2, transporting the obtained carbon black flue gas to air for preheating Heat exchange with the cold air in the filter, and then transported to the main bag filter for separation of tail gas and carbon black after passing through a series of heat exchange equipment; S3, part of the carbon black tail gas separated by the main bag filter is sent to the power generation boiler, and Part of it is sent to the tail gas combustion furnace to provide heat for carbon black drying. The invention effectively treats different types of tail gas in carbon black waste gas, and at the same time thoroughly treats tail gas in different flow directions, greatly reducing the pollution caused by harmful gases to the surrounding environment, and realizing energy saving and consumption reduction in production and comprehensive waste gas Governance and compliance emission can not only promote the transformation and upgrading of carbon black production process, but also achieve good social and environmental benefits.

Description

technical field [0001] The invention relates to the technical field of carbon black, in particular to a carbon black waste gas treatment process. Background technique [0002] Carbon black is a kind of amorphous carbon, light, loose and extremely fine black powder, with a very large surface area, and it is a carbonaceous substance (coal, natural gas, heavy oil, fuel oil, etc.) that undergoes incomplete combustion or heating under the condition of insufficient air. products of decomposition. Specific gravity 1.8-2.1. The one made from natural gas is called "gas black", the one made from oil is called "lamp black", and the one made from acetylene is called "acetylene black". In addition, there are "trough black" and "furnace black". According to the performance of carbon black, there are "reinforcing carbon black", "conductive carbon black", "wear-resistant carbon black" and so on. It can be used as a black dye, used to make Chinese ink, printing ink, paint, etc., and also...

Problems solved by technology

[0003] At present, in the treatment of carbon black tail gas and waste gas, it is impossible to treat different sources of waste gas separately, resulting in the exhaust gas still causing serious pollution to the environment, and in the process of treating carbon black tail gas and waste gas, it is impossible to treat different flow The carbon black tail gas and exhaust gas are thoroughly treated. Therefore, we propose a carbon black exhaust gas treatment process to solve the above problems
