Description

Technical Field

[0001] This utility model belongs to the field of nickel mud treatment technology, and in particular relates to a nickel mud dissolution and leaching device. Background Technology

[0002] Nickel sludge mainly originates from battery waste and the electroplating process. It contains high concentrations of nickel (up to 20% or more), as well as metallic and non-metallic elements such as iron, copper, and zinc. Electroplating sludge, on the other hand, comes from electroplating wastewater treatment. It has a complex composition, high water content, and contains heavy metal hydroxides and soluble salts such as copper, nickel, and chromium. In terms of hazards, the heavy metals in both types of sludge, such as nickel and chromium, are toxic. If not properly treated, they can pollute soil and water sources and accumulate through the food chain, harming human health. Hexavalent chromium in electroplating sludge is a strong carcinogen, and excessive nickel can cause damage to the nervous system. Regarding treatment technology, the disposal of nickel sludge... Treatment methods include heavy metal ion exchange, chemical reduction, and biological reduction. Electroplating sludge treatment technologies are even more diverse, such as solidification and stabilization, plasma methods, pyrometallurgical recovery (high-temperature reduction smelting, oxygen-enriched side-blown smelting), and wet recovery (acid leaching, ammonia leaching). Currently, factories typically use dissolving tanks to dissolve nickel sludge, transferring the nickel ions into the solution. However, after draining the solution, the remaining waste residue in the dissolving tank is difficult to handle and requires manual removal, which is very inconvenient. Therefore, it is necessary to provide a nickel sludge dissolving and leaching device to solve the above problems. Utility Model Content
