Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] 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

The invention discloses a device and method for producing active carbon black. The producing device mainly comprises a reaction furnace, an air pre-heater, an oil pre-heater and a carbon black grading device. The carbon black grading device comprises a barrel body which is provided with an upper channel and a lower channel. A flow diversion column is arranged in the barrel body and is provided with a flow diversion sheet in a spiral mode. The side end of the flow diversion sheet makes contact with the inner side wall of the barrel body. The side wall of the barrel body is provided with a plurality of through channels. A device for removing accumulated carbon of the carbon black grading device is installed in the space inside the flow diversion column, and accumulated carbon on the barrel wall can be removed according to the characteristic of water paint. Compared with the prior art, the device has the advantages that the accumulated carbon produced in the carbon black grading device by carbon black smoke dust can be removed, and not only is use efficiency 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 barrel wall and surrounds the through channels, and then the carbon black smoke dust cannot flow smoothly are solved.

Description

technical field [0001] The invention relates to a preparation device and a preparation method of activated carbon black. 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 pr...
