Problems solved by technology

[0005] 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

[0109] 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 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 tail gas is passed into the production process of white carbon black, and the nitrogen gas is passed into the wet mixing process, and a large amount of heat is generated in the process of white carbon black and wet mixing use.

[0118]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 filler, synthetic rubber and wet rubber compound integrated production method. A filler is selected from carbon black, white carbon black or a combination of the carbon black and the white carbon black. Compared with traditional and respective independent technologies, the method disclosed in the invention has the advantages of omitting of the post-treatment technologies of the filler and a synthetic rubber, realization of the cycle of sodium carbonate, and full utilization of carbon dioxide and heat generated in a traditional carbon black production technology. So the method can reduce production equipment and simultaneously realize the low carbon and low pollution discharge through the integrated optimization of the process flow in order to reach the recycle purpose.

Description

technical field [0001] The invention relates to the field of rubber, in particular to an integrated production method of filler, synthetic rubber and wet mixing rubber. Background technique [0002] In the modern rubber industry, more than 99% of the rubber used to manufacture products contains fine particle powder fillers. On the one hand, their application is used as a reinforcing material for rubber, improving the physical and mechanical properties of rubber and improving the performance of rubber products; the other is 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. [0003] The traditional dry mixing technology has become the research focus of more and more enterprises and scientific research institutes due to its long mixing...
