A kind of production method of n330 carbon black

Abstract

The invention provides an N330 carbon black production method. The process is simple and practical, and produced carbon black is better in performance. A hard carbon black reaction furnace is used for production, and the volume ratio of air to natural gas entering the reaction furnace is (18-19):1, so that more redundant air is generated to take participation in secondary combustion in a reaction chamber; raw oil enters the reaction chamber according to the spray amount of 440 kg / h; each kilogram of raw oil needs 2-3 m<3> of mixed gas composed of air and natural gas; the temperature of secondary combustion in the reaction chamber is controlled to be 1500-1600 DEG C; a plurality of gas inlets are evenly formed in a spray burner in the radial direction, and natural gas enters the gas inlets in a radial surrounding and axial mode so as to improve combustion efficiency; a first quenching section and a second quenching section are arranged at an outlet of the reaction furnace, the temperature of the first quenching section is controlled to be 900-950 DEG C, the temperature of the second quenching section is controlled to be 700-950 DEG C, and accordingly reaction time is prolonged; after carbon black is subjected to wet granulation, mixed gas composed of tail gas generated after carbon black production and air is introduced to dry the carbon black at the temperature of 300 DEG C; the tail gas and the air are mixed according to the volume ratio of (1.5-1.6):1.

Description

technical field [0001] The invention relates to a production method of carbon black, in particular to a production method of N330 carbon black. Background technique [0002] Carbon black is a product obtained by incomplete combustion or thermal decomposition of organic substances such as natural gas, heavy oil, and fuel oil under conditions of insufficient air. N330 carbon black is a high wear-resistant carbon black with good reinforcing properties. It is mainly used as a rubber reinforcing agent to improve the physical and mechanical properties and dynamic properties of rubber products. It is used in tire treads, cord rubber, sidewalls, conveyor belts, rubber Rolls and various rubber industrial products can endow the rubber with good stretchability, tear resistance, wear resistance and elasticity, reduce compression heat generation, reduce rolling resistance, and improve wet grip. It has a wide range of uses. my country is a big country of tire production, and the carbon b...

AI Technical Summary

Problems solved by technology

my country is a big country of tire production, and the carbon black industry has a huge market potential. However, the current carbon black industry has problems such as small number of samples, immature technology, difficulty in large-scale scale, and severe situation. In particular, the production process of hard carbon black is relatively complicated. , product performance is not easy to control
