Description
Technical Field
The invention relates to an atomization distributor, in particular to a gas-driven mechanical atomization distributor.
Background
Crude oil is known to be a viscous oily liquid having a special odor, and is a mixture of various liquid hydrocarbons such as alkanes, cycloalkanes, aromatic hydrocarbons, olefins, and the like, and its main components are carbon and hydrogen, and elements such as sulfur, chlorine, oxygen, nitrogen, and the like. In the process of refining crude oil, corrosive substances such as hydrogen sulfide, sulfuric acid, hydrochloric acid, ammonia, cyanide and the like are generated due to heating and the like, and the corrosive substances can cause corrosion to equipment and pipelines of oil refining devices to different degrees. Meanwhile, with the gradual exhaustion of fossil energy, high-quality crude oil is gradually reduced, and low-quality crude oil with high sulfur value and high acid value is continuously developed and applied. The inferior crude oil contains more corrosive substances, and compared with the superior crude oil, the inferior crude oil has higher corrosiveness to the oil refining device, so that corresponding anti-corrosion measures are needed.
The corrosion prevention measures adopted at present mainly comprise equipment corrosion prevention and process corrosion prevention, wherein the equipment corrosion prevention comprises the steps of improving the material grade of equipment or a pipeline and increasing the corrosion resistance of the equipment, the corrosion prevention method can greatly increase the investment of the equipment, and therefore, the application is limited, the process corrosion prevention means that corrosion inhibitor injection points are arranged at proper positions, and the corrosion inhibitor injection points are used for carrying out neutralization reaction with corrosive substances in a gas-phase raw material medium through injecting corresponding neutralizing mediums, and a protective layer of the corrosion-resistant medium is formed on the inner wall of a pipeline.
When the corrosion inhibitor is injected at the injection point position by adopting the process corrosion prevention, the injection form has great influence on the use effect of the corrosion inhibitor. The existing injection mode is mainly straight pipe direct injection, the corrosion inhibitor injected in the mode directly flows along the lower part of the inner wall of the pipeline, cannot fully contact with corrosive substances in a gas phase medium in the pipeline, and has neutralization reaction, so that the technical purpose of corrosion prevention cannot be achieved. If the injection mode is adopted for a long time, the injected corrosion inhibitor cannot effectively play a role in preventing corrosion, so that the accident risk of equipment or pipeline corrosion leakage cannot be avoided, and meanwhile, the corrosion inhibitor is wasted. Further, since the corrosion inhibitor cannot be uniformly dispersed into the pipeline, an effective corrosion-resistant protective film cannot be formed on the inner wall of the pipeline, and a desired corrosion-inhibitor protective film cannot be formed at the initial start-up period of the device, namely, the pre-film period of the corrosion inhibitor injection.
With the continuous intensive research of corrosion inhibitors, the novel corrosion inhibitor with small dosage of the injection agent and high corrosion prevention efficiency is applied in a large quantity, compared with the corrosion inhibitor used in the past, the injection flow of the novel corrosion inhibitor is very tiny (5-20 liters/hour), and for the corrosion inhibitor with tiny flow, if the conventional straight pipe is still adopted for direct injection in the injection mode, the injected corrosion inhibitor can drop below the injection point straight pipe on the inner wall of the pipeline, the process aim of neutralizing the corrosion inhibitor with corrosive substances in the gas phase raw material medium can not be realized, a protective film of the corrosion prevention medium can not be formed on the inner wall of the pipeline, and the use cost and the like are greatly increased.

The basic principle of the invention is as follows: the kinetic energy of the gas in the pipeline is converted into mechanical energy to atomize the liquid phase corrosion inhibitor 11. Namely, when the gas-driven mechanical atomization distributor is arranged in the pipeline 8, the high-speed flow of the gas-phase raw material medium 10 in the pipeline 8 drives the impeller 6 to rotate, the rotating impeller 6 drives the porous distributor 4 to concentrically rotate, at the moment, the liquid-phase corrosion inhibitor 11 from the liquid inlet pipe 7 enters the porous distributor 4 through the liquid channel on the hollow main shaft 3, and the liquid-phase corrosion inhibitor 11 is uniformly distributed in the pipeline 8 and on the inner wall of the pipeline 8 or the inner wall of the protective layer 9 under the rotary centrifugal action of the porous distributor 4, so that the high-efficiency contact reaction of the gas-phase raw material medium 10 and the liquid-phase corrosion inhibitor 11 is ensured, the corrosion of corrosive substances to the equipment and the pipeline 8 is greatly reduced, and meanwhile, the liquid-phase corrosion inhibitor 11 is uniformly distributed on the circumference, so that an effective corrosion inhibitor protective layer can be formed on the inner wall of the pipeline.
