An online high-temperature separation and purification device and method for carbon black fuel oil

Abstract

The invention discloses an online high-temperature separation and purification device and method for carbon black fuel oil, belonging to the technical field of carbon black fuel oil treatment equipment. The separation and purification device includes a pressurization device, a separation device and a purification device. The pressurization device and the separation device pass through the first One oil outlet pipe is connected to the connecting hose, and the separation device is connected to the purification device through the second oil outlet pipe. The pressurizing device is used to pressurize the carbon black fuel oil to compress the carbon black fuel oil to be separated and purified. The separation device is used to Centrifuge the carbon black fuel oil to remove moisture impurities in the carbon black fuel oil. The purification device is used to purify the centrifuged carbon black fuel oil. The separation and purification of shutdown improves the processing efficiency and has a high degree of automation.

Description

technical field [0001] The invention relates to the technical field of carbon black fuel oil treatment equipment, in particular to an online high-temperature separation and purification device and method for carbon black fuel oil. Background technique [0002] In the process of carbon black production, due to the particularity and diversification of raw materials for production, there are often situations where the reactants are mixed together due to insufficient reaction after the reaction, so the fuel oil in it needs to be separated and purified , and the process is relatively complicated, and the actual purification method is also relatively simple, resulting in a part of impurities in the separated fuel oil. In order to solve this problem, the patent application number CN201510613555.8 discloses a carbon black and its preparation method and a preparation device, the preparation method comprising: (A) contacting the carbonaceous material with high-temperature plasma to ca...

[0002] In the process of carbon black production, due to the particularity and diversification of raw materials for production, there are often situations where the reactants are mixed together due to insufficient reaction after the reaction, so the fuel oil in it needs to be separated and purified , and the process is relatively complicated, and the actual purification method is also relatively simple, resulting in a part of impurities in the separated fuel oil. In order to solve this problem, the patent application number CN201510613555.8 discloses a carbon black and its preparation method and a preparation device, the preparation method comprising: (A) contacting the carbonaceous material with high-temperature plasma to carry out a cracking reaction at 1400-1800° C. to obtain a cracked product rich in acetylene; (B) making the cracked product obtained in step (A) Carry out acetylene decomposition reaction to obtain carbon black. This technology can realize the production of carbon black by using at least one of coal, fuel oil and natural gas as carbonaceous materials, reducing the steps of acetylene purification and purification, and shortening the production process of carbon black. The production cost is reduced, but this prior art mainly designs the whole system for the preparation of carbon black, and does not carry out targeted design for the separation and purification of carbon black fuel oil.
