Description

Acidolysis tank Technical Field The utility model relates to the field of magnesium chloride production, in particular to an acidolysis tank. Background In inland areas, magnesium chloride (MgCl 2) is produced from magnesium-rich ores by a low-cost and environmentally friendly method, which provides an important raw material for the electrolysis of magnesium, and is widely used as a powerful water-absorbing/moisture-absorbing agent, moisture-proof agent, antioxidant and an important component of some medicines in various fields such as national defense, chemical industry, pharmacy and metallurgy. In the field of smelting magnesium metal, dolomite has recently taken up more than 99% of the consumption of magnesium metal by a thermal reduction method (commonly called the Pidgeon method) and its modified thermal reduction method. However, this method requires high-temperature calcination and high-temperature reduction while using a large amount of ferrosilicon, which results in not only a high content of magnesium remaining in the reduction residues (i.e., magnesium slag, in which the content of magnesium oxide is generally higher than 10%), but also these residues become "hazardous micro waste". In addition, because the effective component of the ore is MgCO 3, the production process of the metal magnesium by the Pidgeon process belongs to the industries of high energy consumption, high pollution, high emission and high cost. Meanwhile, salt lake brine (or scraps of carnallite and potash fertilizer production) is used as a raw material to extract magnesium chloride for electrolytic magnesium production, which is originally a more green magnesium production path. However, since electrolytic magnesium requires high quality anhydrous magnesium chloride as a raw material, the process of preparing anhydrous magnesium chloride has been invented so far from the last 60 th century, and the process of preparing anhydrous magnesium chloride is still very difficult, the technical route is complex, and the cost is high. The prepared magnesium metal is high in price, and a multi-stage hydrated magnesium chloride (MgCl 2·6H2 O) dehydration technology developed by the mechanisms such as the Dow chemistry and the like still faces great challenges in mass production of anhydrous magnesium chloride, namely high cost, low efficiency and poor production stability. In addition, the current area requiring magnesium production is often far away from salt lakes or seasides, so that the hydrated magnesium chloride (MgCl 2·6H2 O with the magnesium content of only 11.95 percent by weight) formed by natural crystallization is transported to the inland area, which has a great deal of inconvenience and no commercial value. Whereas dolomite with a lower magnesium content has an average magnesium content of 13.9% wt, magnesite has an average magnesium content of 27.13% wt. Thus, extraction of magnesium chloride by ore conversion is particularly necessary.
