Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] see Figure 1 to Figure 9 Shown: The equipment required for the production of carbon black includes reaction furnace 1, air preheater 3, oil preheater 2 and carbon black classification device 4, and activation device 6 is required to produce activated carbon black. These equipments are sequentially connected through the smoke pipe 5 in the order of the reaction furnace 1, the oil preheater 2, the air preheater 3, the carbon black classification device 4, and the activation device 6. Wherein between the oil preheater 2 and the reaction furnace 1, an oil pipeline 21 is also connected, a preheating air pipeline 31 is connected between the air preheater 3 and the reaction furnace 1, and a preheating air pipeline 31 is connected with the carbon black classifying device 4. B preheated air duct 32 .

Abstract

Provided are carbon black and a preparation device. The preparation device mainly comprises a reaction furnace, an air preheater, an oil preheater and a carbon black grading device. The carbon black grading device comprises a cylinder which is provided with an upper channel and a lower channel, a diversion column is arranged in the cylinder, a diversion sheet is arranged on the diversion column in a spiral mode, the side end of the diversion sheet makes contact with the inner side wall of the cylinder, a plurality of through grooves are formed in the side wall of the cylinder, and accumulated carbon on the wall of the cylinder is removed by the characteristics that water-based paint films resolve easily when being heated and is soluble in organic solvents. Compared with the prior art, the preparation device can remove the accumulated carbon caused by carbon black smoke in the carbon black grading device, and not only is utilization rate of the device improved, but also the service life of the device is prolonged. The problems that after the carbon black grading device is used for a long time, carbon is accumulated on the wall of the cylinder and the surroundings of the through grooves and then the circulation of the carbon black smoke is not smooth are solved.

Description

technical field [0001] The invention relates to a carbon black and a preparation device. Background technique [0002] Carbon black is a light, loose and very fine black powder whose main component is amorphous carbon. It has a very large surface area ranging from 10-3000m2 / g. The product obtained by incomplete combustion or thermal decomposition (with greater adhesion). Carbon black has a wide range of applications. It can be used as a black dye to make Chinese ink, printing ink, paint, etc. It is also used as a reinforcing agent for rubber and plays an important role in the industrial field. [0003] Traditionally, in the carbon black production process, air and fuel are burned in a reactor, and the raw materials are sprayed into the burning flame after being atomized, and carbon black is generated by high-temperature pyrolysis. Carbon black is suspended in the gas to form flue gas. After being quenched, the flue gas is sent to the air preheater and oil preheater for fu...
