Abstract

A precious metal recovery device for waste liquid incineration comprises a storage tank which is arranged horizontally and inclines upwards by 15 degrees. An upright incineration tower and an upright scrubber tower are arranged on the side wall of the top end of the storage tank side by side. The bottom end of the incineration tower and the bottom end of the scrubber tower are both communicated with the storage tank. The incineration tower comprises a tower drum. The top end of the tower drum is sealed. The tower drum is divided into an upper combustion section and a lower splat cooling section. A waste liquid air inlet pipeline is arranged on the side wall of the middle of the combustion section. An atomization spray pipe is arranged on the side wall of the splat cooling section. Gas-state sufficient combustion is achieved, internal nitrogen, phosphorus and chlorine which are complex in component and low in content are treated better, a solvent is prepared by fully using high heat, fuel consumption is reduced, and the low loss rate of precious metal is guaranteed.

Description

technical field [0001] The invention relates to the field of precious metal recovery, in particular to a waste liquid incineration recovery precious metal device. Background technique [0002] Environmentally friendly waste disposal, incineration is an important process. The waste liquid contains precious metals that need to be recovered, which is also a normal state of spent catalysts containing precious metals. The combination of the two is the process of disposing of organic waste liquid while recycling precious metals. [0003] The waste liquid containing precious metals is mostly organic solvents, mostly hydrocarbons, and the molecular structure is C X h Y o Z， Some medical wastes contain a small amount of pharmaceutical intermediates, nitrogen-containing, chlorine-containing, and some chemical waste liquids contain phosphorus and iodine; but the main components are hydrocarbon bonds. The common characteristics are that the calorific value is very high, there are t...
