The metal sodium is an important basic chemical raw material, is also a common substance for demonstration medicines and scientific research laboratories which are necessary for teaching laboratories, and is often present in laboratory hazardous waste collected by hazardous waste disposal units and hazardous waste of other industries. The metal sodium has very active chemical properties, is very easy to react with water, alcohol, acid and the like, releases a large amount of heat and inflammable and explosive hydrogen, and the heat ignites and detonates the hydrogen, so that fire or explosion occurs, and the explosion accident caused by the metal sodium slag used for reaction or dehydration pretreatment occurs due to reasons such as management, label extinction and the like, so that the waste metal sodium is treated, completely quenched and inactivated, potential safety hazards are eliminated, and the metal sodium is an important task from the use source to the waste disposal terminal.
At present, waste metal sodium is treated by pretreating sodium as reactive waste, and the sodium is fed and burned from a side gate alone without mixing with other dangerous waste, especially water, alcohol and acid. However, this method generates sodium peroxide and sodium superoxide in the incinerator, and when slag is collected, it is liable to react with cooling water to splash, thereby generating active oxygen which is harmful to health and increasing the alkaline corrosiveness of slag.
In view of the above problems, the chinese patent application No. 2020113381308 discloses a sodium metal treatment system, which discloses a method of melting sodium in a melting furnace, reacting the melted sodium with hot air in a reaction furnace to form sodium oxide and sodium peroxide, reacting the sodium oxide with water to form sodium hydroxide, and neutralizing the sodium hydroxide with water in a neutralization tank, but the system of the method is complex, has a large investment, and is not suitable for medium-small scale treatment. The Chinese patent application No. 2006101458563 discloses a method for destroying waste sodium, potassium and sodium-potassium alloy, wherein the method is disclosed that after the waste sodium is burnt, the explosion is controlled by spraying millimeter-level water mist, but the method needs repeated manual operation, and has low automation degree.

The application mode and the principle of the utility model are as follows: when the utility model is used, the waste metal sodium to be treated is poured onto the screen plate through the pouring opening, the coverage rate of the waste metal sodium on the screen plate reaches 50-80%, then the pouring opening is sealed through the sealing cover, the ultrasonic atomizer is started, water in the water reservoir enters the ultrasonic atomizer and is atomized into water mist (water vapor) of 1-5 microns, then the generated water mist is transmitted into the reaction container by utilizing the fan blades of the ultrasonic atomizer and the suction pump arranged on the pipeline, the water mist is transmitted into the inner cavity of the reaction container and then is diffused, the waste metal sodium contacted with the screen plate of the reaction container reacts with the water mist, sodium hydroxide is generated by the reaction of the water mist and sodium oxide on the surface layer of the waste metal sodium, and sodium hydroxide and hydrogen are generated by the reaction of the water mist and sodium hydroxide on the inner layer of the waste metal sodium after the reaction of the sodium oxide on the surface layer of the waste metal sodium is finished, and the sodium hydroxide is dissolved in the water mist. On one hand, the water mist is condensed and then gathered to the bottom of the reaction vessel, and is discharged from a lower discharge pipe at the bottom of the reaction vessel, wherein the lower discharge pipe can be connected with a neutralization device to neutralize the liquid containing sodium hydroxide; on the other hand, the generated hydrogen and the water mist absorbing the heat are discharged from an upper discharge pipe of the reaction vessel, and the upper discharge pipe can be connected with a collecting device to collect the discharged water mist and the hydrogen for further treatment. The waste metal sodium is in a reaction vessel, and the whole process can not generate dangerous substances and energy aggregation through reaction with water mist, and the reaction vessel is always kept at normal temperature, and the whole process is in a very stable state, so that the waste metal sodium can be safely treated.
In addition, the small waste metal sodium on the screen plate possibly passes through the meshes of the screen plate and falls into the bottom of the inner cavity of the reaction container, the small waste metal sodium can react with liquid which is not discharged from the bottom and water mist in the inner cavity at the bottom, and the small waste metal sodium can not generate violent reaction under the action of the water mist and the liquid due to the small volume.
