Description

Technical Field

[0001] The utility model belongs to the field of waste catalyst refining equipment, and in particular relates to waste catalyst raw material refining equipment capable of collecting waste materials. Background Art

[0002] Precious metals and their compounds usually have unique physical and chemical properties, and are therefore widely used in the fields of petrochemicals, aerospace, electronics, atomic energy, laboratory instruments, medicine, etc. Since some precious metals have excellent catalytic properties, catalysts containing precious metals are widely used in the chemical industry. Catalysts have a certain safe lifespan. After the service life is exceeded, the catalyst will become ineffective or the catalytic efficiency will be reduced and will no longer be used. Since precious metals are very rare on the earth, it is necessary to use waste catalyst raw material refining equipment to refine and recover precious metals from waste catalysts.

[0003] At present, most of the waste catalyst raw material refining equipment on the market adopts wet refining to chemically treat the solution containing metal ions, so that the metal ions are reduced to pure metals to recover the precious metals in the waste catalyst. During the refining reaction, waste and waste liquid will be generated. The existing waste catalyst raw material refining equipment often does not have the ability to collect waste, and direct discharge will cause pollution to the environment.

[0004] Therefore, in order to address the problem that the existing waste catalyst raw material refining equipment does not have the ability to collect waste materials and directly discharges the waste liquid and waste materials generated by refining, which easily pollutes the environment, the existing waste catalyst raw material refining equipment is improved to have the ability to collect waste materials. Utility Model Content
