Detoxification device and detoxification method of carbonylated alloy

Abstract

The invention discloses a detoxification device of a carbonylated alloy. The detoxification device comprises a steel belt detoxification furnace sequentially divided into a detoxification furnace material distribution area, a detoxification furnace carbonylated alloy detoxification area and a detoxification furnace cooling area through two gas curtains. A detoxification furnace argon inlet is formed in the end, close to the detoxification furnace material distribution area, of the detoxification furnace carbonylated alloy detoxification area, and a detoxification furnace exhaust port is formedin the end, close to the detoxification furnace cooling area, of the detoxification furnace carbonylated alloy detoxification area. The detoxification furnace exhaust port is connected with one end of a waste gas pipeline provided with an exhaust valve, and the other end of the waste gas pipeline is connected with a waste gas induced draft fan. During detoxification, firstly, the carbonylated alloy passes through the detoxification furnace material distribution area and enters the detoxification furnace carbonylated alloy detoxification area, then passes through the detoxification furnace cooling area and comes out and enters a hopper placed in advance, and detoxification of the carbonylated alloy is completed. By means of the detoxification device, the detoxification efficiency of the carbonylated alloy can be improved, the detoxification effect is better, carbonylated alloy detoxification is efficient and reliable, and recycling of other valuable metal in the subsequent carbonylatedalloy obtained through carbonylation method refining is facilitated.

Description

technical field [0001] The invention belongs to the technical field of nickel refining, and in particular relates to a carbonylated alloy detoxification device and a detoxification method for nickel refined by carbonyl method. Background technique [0002] At present, the raw materials used in the synthesis process of nickel carbonyl are all nickel-rich raw materials. Due to the difference in structure, nickel enrichment degree and appearance shape of various nickel-rich raw materials, there are follow-up other valuable metals after carbonylation refining. Recycling issues. Since nickel carbonyl is a highly toxic substance, the subsequent recovery of other valuable metals, no matter what process is used, certainly does not want the raw materials to contain highly toxic substances. However, nickel carbonyl will remain in the form of gas adsorption in the carbonylated alloy of nickel refined by the carbonylation method, which will bring a lot of inconvenience to the recovery ...
