Recovery process and apparatus for solid state metal sodium waste residue

Abstract

The present invention relates to a recovery process and an apparatus for solid state metal sodium waste residue. The process is characterized by comprising: placing solid state metal sodium waste residue into a heating furnace (1) to carry out high temperature heating to obtain sodium vapor so as to separate sodium and other elements through distillation separation, carrying out condensation on the sodium vapor to obtain liquid state sodium, and conveying the liquid state sodium to a sodium casting machine to cast sodium. According to the present invention, the sodium residue distillation method is adopted to recover and utilize the metal sodium from the sodium residue so as to provide characteristics of low energy consumption, high yield and the like; the raw materials use the industrial waste so as to achieve resource saving and created economic benefits; trial results prove that purity of the metal sodium produced by using the process can be 99.9%, and is higher than purity 99.7% of the metal sodium produced by using the original process; and continuous vacuum pumping is designed in the distillation process so as to enhance a sodium residue recovery rate, shorten a distillation time and meet the optimum process conditions of continuous production.

Description

Technical field [0001] The invention relates to a process and device for recovering solid metal sodium waste residue. Background technique [0002] In recent years, with the development of society, creating an environmentally friendly and resource-saving enterprise has become the mainstream consciousness of current economic development. The processing method of industrial waste (solid metal sodium waste slag, sodium slag) produced every year in the metal sodium production industry is mainly exported to downstream enterprises. However, in recent years, sodium slag customers have upgraded the process and the traditional sodium slag is no longer in line with Due to its production requirements, the sodium slag produced by the original process is no longer used, resulting in a sharp increase in sodium slag inventory of various sodium metal manufacturers, and problems such as potential safety hazards. Finding new methods, methods and processes for handling sodium slag has become Top p...

The industrial waste slag (solid metal sodium slag, referred to as sodium slag) produced every year in the sodium metal production industry is mainly exported to downstream enterprises. However, in recent years, sodium slag customers have upgraded the process, and traditional sodium slag is no longer suitable Its production requirements, so the sodium slag produced by the original process is no longer used, resulting in a sharp increase in the inventory of sodium metal slag in various metal sodium manufacturers, and leading to problems such as potential safety hazards. Finding new methods, methods and processes for processing sodium slag has become top priority
