Example Embodiment

[0068] Example 1:

[0069] The embodiment of the present invention provides a novel waste catalyst cleaning ball milling process, such as Figure 1-Figure 9 shown, including the following steps:

[0070] Step 1: put the waste catalyst into the drum screening and cleaning machine 1, and screen the waste catalyst for ash cleaning;

[0071] Step 2: The waste catalyst for removing dust is transported to the bucket 4 of the lifting tipper 3 through the material transition mechanism 2, and the waste catalyst for removing dust is transported to the ball mill 5 through the lifting tipper 3;

[0072] Step 3: Use the ball mill 5 to grind the spent catalyst, and add sodium hydroxide solution to the ball mill 5 through the liquid addition device 6 .

[0073] The working principle and beneficial effects of the above technical solutions are as follows: first, the waste catalyst is put into the drum screening and cleaning machine 1, and the waste catalyst is screened and cleaned, and then ...

Abstract

The invention provides a novel waste catalyst cleaning and ball-milling process which comprises the following steps: putting a waste catalyst into a roller screening and cleaning machine, and carrying out dust screening and cleaning on the waste catalyst; the dedusted waste catalyst is conveyed into a hopper of a lifting tipping bucket machine through a material transition mechanism, and the dedusted waste catalyst is conveyed to a ball mill through the lifting tipping bucket machine; a ball mill is used for grinding the waste catalyst, and a sodium hydroxide solution is added into the ball mill through a liquid adding device. According to the device, dust in the catalyst can be removed through dust screening of the roller screening and cleaning machine, then the ball mill is used for grinding, the catalyst is more soluble in water, valuable crystals are better formed, a sodium hydroxide solution is added through the liquid adding device, and valuable crystalline sodium tungstate is generated after heating, so that the utilization rate of resources is increased; meanwhile, direct burying of the catalyst is avoided, pollution to the environment is reduced, and the method is more environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of catalyst treatment, in particular to a new ball-milling process for cleaning waste catalysts. Background technique [0002] Catalysts will become waste catalysts after long-term use. After the spent catalysts are returned to the factory, the useful catalysts will be selected by the staff and regenerated, while the catalysts with no regeneration value are mostly buried, and the catalysts with no regeneration value are mostly buried. Valuable sodium tungstate can be produced through processing. Therefore, the existing catalyst burial treatment method does not use waste catalyst to process valuable sodium tungstate, which will not only cause waste of resources, but also pollute the environment. SUMMARY OF THE INVENTION [0003] The invention provides a novel waste catalyst cleaning ball milling process, which is used to solve the technical problem that the existing catalyst burial treatment method does not...
