Abstract

The utility model discloses a metallic sodium secondary refiner, comprising a refiner body. A filtering barrel is arranged in the refiner body; a plurality of filtering holes are arranged in the wall of the filtering barrel; and a filtering screen is arranged on the external wall of the refiner barrel . According to the metallic sodium secondary refiner, the secondary separation of sodium and the recovery of sodium in primary sodium slag are realized, so that the yielding rate of products is improved; thus, the production cost is reduced and the economic benefit is improved.

Description

Sodium Metal 99.5 secondary refining device

Technical field

The utility model relates to technical field of chemical, relates in particular to a kind of sodium Metal 99.5 and uses the secondary refining device.

Background technology

Sodium Metal 99.5 is important chemical material and nuclear reactor thermal barrier, is widely used in printing and dyeing, medicine, precious metal refinement, petrochemical industry or the like industry-by-industry.

Present domestic sodium Metal 99.5 is mainly used in ammonia sodium legal system sodium cyanide, utilizes the strong reducing property of sodium, with sodium Metal 99.5 from Repone K displace potassium metal, sodium Metal 99.5 reduction titanium tetrachloride system Titanium Sponge 40-60 mesh; Can also make rare metal tantalum and niobium, utilize sodium to be prone to form the character of alloy, generate tetraethyllead with sodium Metal 99.5 preparation lead sodium alloy; Improve the octane value of gasoline, strengthen the antiknock ability of gasoline, sodium also is used to make sodium-potassium eutectic and makes refrigerant; Produce sodiumperoxide with sodium Metal 99.5, as the SYNTHETIC OPTICAL WHITNER of bleachinging and dyeing industry, sodium can also be processed the sodium superoxide as artificial oxygen source; Produce sodium hydride with sodium Metal 99.5,, generate sodium amide with sodium Metal 99.5 and ammonia react as the agent of derusting of metallurgical industry galvanized iron sheet; Sodium amide is that dyestuffs industries is made indigo midbody, and high pure sodium can also be as the thermal barrier of reactor.

Electrolyzing fused sodium-chlor is adopted in sodium Metal 99.5 production, is dissolved in the product owing to needing adding auxiliary material solubility promoter in electrolytic process, will produce impurity so in process of production, and this just need remove in subsequent production to improve the quality of products; Sodium Metal 99.5 in the electrolyzer output is that bullion need be made with extra care, get in treater, through the insulation of electrolysis heat at 105～110 ℃; 24 hours final vacuums of sedimentation change material, and the residual sodium slag is discharged through mucking machine, and we are referred to as the sodium slag one time; Domestic is directly a sodium slag to be taken out as product with the provisional capital, and the content of sodium is more than 85% in the sodium slag like this, causes the waste loss; Product yield is low, has increased production cost.

The utility model content

The utility model technical problem to be solved provides a kind of sodium Metal 99.5 secondary refining device of practicing thrift cost, improving product yield.

For solving the problems of the technologies described above; The technical scheme of the utility model is: sodium Metal 99.5 secondary refining device, comprise the treater body, and in the said treater body filtration barrel body is installed; Said cartridge filter body wall is provided with some filter pore, and said filtration barrel body outer wall is provided with filtering net.

As the improvement to technique scheme, said treater body outer wall is provided with thermal insulation layer.

As optimized technical scheme, said thermal insulation layer is the electrical heat tracing layer.

As optimized technical scheme, said filtering net has increased intensity and has prolonged work-ing life for filtering steel mesh.

Principle of work: through sodium Metal 99.5 secondary refining device; A sodium slag is put in the secondary refining device again, added under the insulation of electrical heat tracing layer 130～150 ℃ of control treater temperature outside, sodium liquefaction back sedimentation is through filtering net and filter pore discharge like this; The HMP contaminant filter is left in the secondary refining device; Make sodium thoroughly separated like this, improved the yield of product, reduced production cost with impurity.

Owing to adopted technique scheme, sodium Metal 99.5 secondary refining device comprises the treater body; Be equipped with in the said treater body, said cartridge filter body wall is provided with some filter pore, and said filtration barrel body outer wall is provided with filtering net; The secondary separation of sodium, the sodium in sodium slag of recovery have been solved; So as to improving product yield, so just reduced production cost, improved economic benefit.

Description of drawings

Accompanying drawing is the structural representation of the utility model embodiment;

Among the figure: 1-treater body; The 2-filtration barrel body; The 3-filter pore; The 4-filtering net; The 5-thermal insulation layer.

Embodiment

Below in conjunction with embodiment; Further set forth the utility model, should be understood that these embodiment only are used to the utility model is described and are not used in the scope of restriction the utility model; Should understand in addition; After the content of having read the utility model instruction, those skilled in the art can do various changes or modification to the utility model, and these equivalent form of values fall within the application's appended claims institute restricted portion equally.

Shown in accompanying drawing, sodium Metal 99.5 secondary refining device comprises treater body 1, in the said treater body 1 filtration barrel body 2 is installed, and said filtration barrel body 2 walls are provided with some filter pore 3, and said filtration barrel body 2 outer walls are provided with filtering net 4.

Said treater body 1 outer wall is provided with thermal insulation layer 5.

Said thermal insulation layer 5 is the electrical heat tracing layer.

Said filtering net 4 has increased intensity and has prolonged work-ing life for filtering steel mesh.

During work,, a sodium slag is put in the secondary refining device again through sodium Metal 99.5 secondary refining device; Add under the insulation of electrical heat tracing layer 130～150 ℃ of control treater temperature outside; Sodium liquefaction back sedimentation is discharged through filtering net 4 and filter pore 3 like this, and the HMP contaminant filter is left in the secondary refining device, makes sodium thoroughly separated with impurity like this; Improve the yield of product, reduced production cost.

More than show and described the advantage of ultimate principle, principal character and the utility model of the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification sheets that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
