Carbon black reaction furnace capable of improving quality and efficiency

Abstract

The invention relates to a carbon black reaction furnace capable of improving quality and efficiency. The carbon black reaction furnace comprises a combustion chamber and a throat pipe section, and first oil guns, second oil guns and third oil guns are evenly arranged on the throat pipe section in the pipe wall direction at intervals; the number of the first oil guns, the number of the second oil guns and the number of the third oil guns are even numbers and are sequentially decreased. The oil guns are arranged in a circumferential array and are arranged in a staggered manner; each oil gun comprises a gun body, an oil inlet pipe, a cooling layer and a sector gear; annular gears meshed with the sector gear are uniformly arranged outside the throat pipe section at intervals; a floor stand is arranged at the bottom of the annular gear, and a pull rod is arranged on the side. By arranging the multiple rows of raw oil spray guns in a staggered manner and adjusting the spray angles of the oil guns, the raw oil reaction temperature distribution is more uniform, and the raw oil atomization effect and the carbon black quality and yield are improved. Meanwhile, the production of carbon black varieties with different forms and structures can be adjusted, so that the production of a single carbon black reaction furnace is more efficient and more productive, and the benefit is increased.

Description

technical field [0001] The application relates to the technical field of carbon black production, in particular to a carbon black reaction furnace capable of improving quality and efficiency. Background technique [0002] Carbon black is a kind of amorphous carbon. Its normal state is light, loose and extremely fine black powder with a very large specific surface area. It is a product obtained by incomplete combustion or thermal decomposition of hydrocarbons under the condition of insufficient air. Carbon black is an indispensable chemical raw material in the industry. Its dyeing and reinforcing properties are used as modification additives for most plastic and rubber products. Among them, the amount of carbon black in tires has reached 80%. Most of them are prepared by the oil furnace method, and the reaction furnace is the most important reaction equipment in the preparation process of this method. The impact on the quality of carbon black is mainly concentrated in the co...

AI Technical Summary

Problems solved by technology

The impact on the quality of carbon black is mainly concentrated in the combustion chamber and the throat section. The fuel combustion in the combustion chamber is insufficient, the temperature of the combustion airflow is not high, the flow rate is low, the degree of atomization of the raw material oil in the throat section is not good, the reaction temperature and pressure are uneven, and the throat Poor layout of pipe raw material oil injection position will affect the quality and variety of carbon black products, resulting in poor efficiency
