A sodium potassium lithium and lithium slag waste treatment device

Abstract

The invention discloses a potassium sodium lithium and lithium slag waste treating device. The device comprises a combustion chamber, a smoke treating device and a smoke exhausting device; a material bin for storing potassium sodium lithium and lithium slag wastes, a lithium storing basin and a combustion platform are arranged in the combustion chamber from top to bottom in a sequence, wherein the material basin is erected on the lithium storing basin; a through lithium discharging leaking hole is formed in a bottom plate of the material basin; the material basin is communicated with the lithium storing basin through the lithium discharging leaking hole; the lithium storing basin is arranged on the combustion platform; the smoke treating device is communicated with the top part of the combustion chamber; the top part of the smoke treating device is communicated with the smoke exhausting device. The device is simple in structure, can safely treat the potassium sodium lithium and lithium slag wastes, is harmless to environment, and large in treatment quantity per unit of time; the lithium can be recovered during treating the wastes, so that the resource waste can be avoided; the economic benefit is increased.

Description

technical field [0001] The invention relates to a waste material treatment device, in particular to a sodium potassium lithium and lithium slag waste treatment device. Background technique [0002] Lithium metal is a silver-white metal with low density, 0.534g / cm2 at room temperature 3 , which is about half of water, is the lightest metal existing in nature, and has a low melting point and the lowest electronegativity. It is widely used in petrochemical, pharmaceutical, rubber synthesis, fine chemical, lithium-ion batteries, aerospace, and nuclear industries. And other fields, known as industrial monosodium glutamate and new energy metal. During the metal lithium smelting and deep processing process, some lithium waste will be produced. For example, in the vacuum distillation purification process, when the low-purity metal lithium is obtained through oil melting, vacuum melting and other processes to obtain high-purity battery-grade metal lithium, it will also produce The ...

Problems solved by technology

However, this process takes a long time to process, and since the slowly oxidized lithium waste may still contain metal lithium or metal sodium, it is prone to explosion during the hydrolysis process, and there is a great potential safety hazard
