Problems solved by technology

[0006] CN102209586A discloses the use of waste heat and residual gases from the industrial production of carbon compounds (such as carbon black, graphite) or from the pyrolysis of sugars for the production of electrical energy, in particular for the operation of furnaces, and / or the use of waste heat in endothermic processes , but the patent does not disclose how to utilize the carbon dioxide produced in the production of carbon black and reduce carbon dioxide emissions
The carbon dioxide in this technology needs to be purchased and stored, so the process is more complicated

Embodiment 1

[0092] The fuel oil is pumped to be mixed with the air provided by the main supply fan and preheated to 850°C by the air preheater, and then combusted in the combustion section to generate a high-temperature combustion airflow of about 1900°C; the raw oil is preheated to a certain temperature by the preheater After that, it is sprayed into the throat section of the reaction furnace, mixed with the high-temperature combustion airflow, and rapidly cracked to produce carbon black flue gas; then, it is sprayed with quenching water to reduce the temperature of the flue gas to terminate the reaction, and the separated carbon black is sent to the In the process of wet mixing rubber, the carbon dioxide separated from the exhaust gas after combustion is used in the production process of white carbon black, and nitrogen is used in the wet mixing process, and a large amount of heat generated is used in the production process of white carbon black and wet mixing. used in the process.

Embodiment 2

[0101] The fuel oil is pumped to be mixed with the air provided by the main supply fan and preheated to 850°C by the air preheater, and then combusted in the combustion section to generate a high-temperature combustion airflow of about 1900°C; the raw material oil is preheated to a certain temperature by the preheater After that, it is sprayed into the throat section of the reaction furnace, mixed with the high-temperature combustion airflow, and rapidly cracked to produce carbon black flue gas; then, it is sprayed with quenched water to reduce the temperature of the flue gas to terminate the reaction, and the separated carbon black is used after passing through the bag filter. In the process of wet mixing rubber, the carbon dioxide produced by the combustion of tail gas in the tail gas boiler is used in the production process of white carbon black, and the heat generated is used in the process of white carbon black and wet mixing.

Abstract

The invention discloses a method for the integrated production of carbon black and white carbon black. Compared with the traditional mutually-independent processes, the method has the effects that the cyclic utilization of sodium carbonate is realized; and carbon dioxide and heat which are generated in the traditional carbon black production process are utilized fully. Thus, by integrating and optimizing the process flows, the purposes of low carbon emission, low pollution emission and cyclic utilization are realized.

Description

[0001] This application is a divisional application of the invention patent application with application number 201310027002.5 and application date of March 25, 2013. technical field [0002] The invention relates to the field of fillers, in particular to an integrated production method of carbon black and white carbon black. Background technique [0003] In the modern rubber industry, more than 99% of the rubber materials used to manufacture rubber products contain fine particle powder fillers. On the one hand, they are used as reinforcing materials for rubber, improving the physical and mechanical properties of rubber and improving the performance of rubber products; On the one hand, rubber products can be endowed with some special functions, such as electrical conductivity, thermal conductivity, radiation resistance, magnetic properties, etc. Therefore, the consumption of fillers in rubber products raw materials has always been second only to rubber itself. [0004] The t...
