Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of petroleum chemical industry, and particularly relates to a combined fuel oil atomizing oil gun for a reaction furnace or a burner in a carbon black production process. BACKGROUND

[0002] At present, fuel oil guns used in the chemical industry have various structural forms according to different fuels and functions, and the working principle is as follows: a general oil gun has a sleeve structure, an inner tube is a fuel pipe, a head part of the fuel pipe is provided with a nozzle with small holes according to design, a tail part is provided with a pipe joint and a connecting pipe of a fuel oil inlet; an outer tube is an atomizing pipe, a head part of the atomizing pipe is connected with an original nozzle, a tail part is provided with a joint connected with the pipe joint of the inner tube and a connecting pipe of a compressed gas inlet; fuel oil enters the fuel pipe from the connecting pipe of the fuel oil inlet, compressed gas enters between the atomizing outer pipe and the fuel pipe from the connecting pipe of the compressed gas inlet; the fuel oil enters the inner cavity of the nozzle together with the compressed gas to be mixed and atomized, and then enters a furnace chamber from a nozzle outlet to be combusted and reacted. In addition, some industries add a kind of thin oil additive (such as potassium carbonate additive used in the carbon black industry) in the reaction furnace, so a kind of additive atomizing gun should be added. Therefore, the combined fuel oil atomizing oil gun is provided, which combines the fuel oil gun and the additive gun together, can separately control the time when the additive and the fuel oil enter the reaction furnace, and can be used as the fuel oil gun only when the additive is not needed, so that the on-site pipeline is neat, management is convenient, and the occupied space is small.
