Abstract
The utility model provides a carbon black raw oil nozzle, which comprises a raw oil cavity and a nitrogen cavity sleeved outside the raw oil cavity, wherein the outlets of the raw oil cavity and the nitrogen cavity are simultaneously connected into a carbon black reaction furnace; the nitrogen cavity comprises an inlet pipe, a gathering chamber and an interlayer which are sequentially connected, and an outlet of the interlayer is connected with the carbon black reaction furnace. The utility model discloses utilize nitrogen gas parcel raw oil when carbon black raw oil gets into carbon black reacting furnace, the oxygen contact in the high temperature flue gas produces the side reaction in reduction raw oil and the reacting furnace, and the carbon black primary particle size aggregate distribution that raw oil pyrolysis reaction generated can be controlled in narrower scope, reduces impurity in the carbon black product simultaneously by a wide margin, the wear resistance of reinforcing rubber vulcanizate.
Description
Technical Field
The utility model relates to a carbon black apparatus for producing field specifically is a carbon black raw oil nozzle.
Background
In the production process of soft carbon black in the prior art, raw material hydrocarbon enters a reaction furnace and is sprayed out of the reaction furnace by a raw material gun and a nozzle, the sprayed raw material hydrocarbon is atomized and is contacted and mixed with hot air flow from a combustion chamber of the reaction furnace, the raw material hydrocarbon is contacted with the hot air flow and then is subjected to endothermic cracking to generate a carbon black product, the atomized raw material hydrocarbon sprayed out of the oil nozzle is contacted and mixed with the hot air flow, partial hard carbon substances are easy to generate, washing screen residues of the carbon black product are generated, and the carbon black product is polluted, so carbon black workers always research how to reduce the washing screen residues of the carbon black product.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve prior art's problem, provide a carbon black raw oil nozzle, the oxygen contact that reduces in raw oil and the reaction furnace high temperature flue gas produces the side reaction, and the carbon black primary particle size aggregate that raw oil pyrolysis reaction generated distributes and can control in narrower scope, reduces impurity in the carbon black product simultaneously by a wide margin, reinforcing rubber vulcanizate's wear resistance.
The utility model comprises a raw oil cavity and a nitrogen cavity sleeved outside the raw oil cavity, wherein the outlets of the raw oil cavity and the nitrogen cavity are simultaneously connected into a carbon black reaction furnace; the nitrogen cavity comprises an inlet pipe, a gathering chamber and an interlayer which are sequentially connected, and an outlet of the interlayer is connected with the carbon black reaction furnace.
The flow ratio of the raw oil to the nitrogen is 100: 5 ~ 8.
The novel practical working method comprises the following steps that raw carbon black oil enters the cylindrical cavity 2 from the inlet end 1, flows out from the outlet end 3 and enters the carbon black reaction furnace, nitrogen enters the gathering chamber 5 from the introducing pipe 4, flows out from the interlayer 6 and enters the carbon black reaction furnace, and the flow ratio of the raw oil to the nitrogen is 100: 5 ~ 8.
The utility model has the advantages that: when the carbon black raw oil enters the carbon black reaction furnace, the nitrogen is used for wrapping the raw oil, so that the side reaction caused by the contact of the raw oil and the oxygen in the high-temperature flue gas in the reaction furnace is reduced, the distribution of carbon black primary particle size aggregates generated by the cracking reaction of the raw oil can be controlled in a narrow range, the impurities in a carbon black product are greatly reduced, and the wear resistance of the rubber vulcanized rubber is enhanced.
