Introduction of platinum, palladium and rhodium recovery and extracting production machine from automobile exhaust catalyst
Due to the lack of domestic platinum group mineral resources and the imbalance between supply and demand, in order to meet domestic demand, most of China's platinum group metals come from the recovery of platinum group metal containing wastes, such as platinum palladium catalyst in petrochemical industry, automobile exhaust catalyst, etc. Different raw materials require different treatment processes. The company designs processes and equipment according to different raw materials to meet production needs.
In September 2021, the project of clean and efficient separation and refining technology and equipment of short process platinum, palladium and rhodium jointly developed by the company in Northeast University was recognized by academicians and recognized as the international advanced level by China Nonferrous Metals Industry Association.

Features of platinum, palladium and rhodium recovery and refining production line:
The company's platinum, palladium and rhodium recovery and refining production line can be designed according to the owner's raw materials and operation habits. It can refine and separate platinum, palladium and rhodium materials with a content of more than 5%, and the content of each finished product can reach more than 99.95%.

High recovery of platinum, palladium and rhodium
In the recovery process of platinum palladium rhodium waste catalyst, there are some processes to oxidize a small number of palladium to form palladium oxide which is difficult to dissolve in acid and alkali. The dissolution rate is very low by direct use of aqua regia or chlorination. In addition, the stability and extremely difficult solubility of rhodium, iridium and ruthenium also cause the low recovery rate of rhodium, iridium and ruthenium. We design a pretreatment process for this material, which can effectively improve its dissolution rate and then improve the recovery of precious metals.

Continuous operation of production line
The company's platinum, palladium and rhodium recovery production line has the following advantages: first, design glass high-level tanks, reduce staff handling and increase production capacity. The traditional PP high-level tank is not suitable for cleaning, which is easy to be dirty and inconvenient to observe the liquid level, resulting in unqualified product quality and large production occupation; The designed glass high-level storage tank well meets the production requirements. The glass material is transparent and easy to clean. 2, In order to facilitate the use and operation of the supporting glass high-level tank, the design of the traditional suction filter bottle is improved and changed to a horizontal filter. After the filtration of the horizontal filter is completed, the liquid guide pipe is connected below and directly enters the glass high-level tank. The horizontal filter has a slight 3O inclination angle to facilitate the vacuum extraction of a small amount of solution. This makes the production process more coherent and smooth and doubles the production capacity.

Reasonable exhaust design
The traditional refining of platinum, palladium and rhodium is carried out in the air cabinet. The exhaust pipe of the air cabinet is normally open. The overall design air volume design requirements are large. Excessive air pressure leads to the volatilization of precious metals with steam, and the loss rate of precious metals is high. The complete set of platinum, palladium and rhodium refining air cabinet is sealed at the mouth of the reaction vessel, and a gas-liquid separation and condensation device is added in the non temperature reaction vessel to condense water vapor, so that the waste gas can directly enter the corresponding treatment pipeline. For example, in the aqua regia dissolution process, the flue gas hood seals the reaction vessel. After the reaction waste gas is condensed and separated by gas-liquid, the condensate containing precious metals returns to the reaction vessel. The nitrogen oxide waste gas directly enters the jet tower for treatment, so as to reduce the diffusion of waste gas and maintain a good workshop environment.
In the production and refining process, from aqua regia to finished products, all precious metal filters and storage tanks are made of glass, transparent and visible. A spray washing system is attached to reduce the occupation of precious metals in the equipment.

Mature waste gas treatment process
The company is equipped with mature precious metal refining waste gas treatment process and multi-stage jet jet high concentration NOx waste gas treatment device, including gas-liquid separator, no oxidation tank, jet jet jet tower, etc. after the treatment of high concentration NOx flue gas (~ 30000 mg / m3) produced by platinum, palladium and rhodium dissolution, the emission concentration is less than 100 mg / m3 and the minimum can be less than 20 mg / m3.
