Step 2: immersion：Flushed discarded power equipment is placed in soaked overnight in running water；
Step 3: alkaline solution is handled：The discarded power equipment of running water soaked overnight is put into alkaline solution, stood
10min；It is again heated to 20 DEG C, stirs 10min while heating, keep 20 DEG C of 10min, be cooled to room temperature, take out discarded electric power
Equipment, retain alkaline solution；
Step 4: acid solution is handled：The discarded power equipment that alkaline solution treats is put into acid solution, stood
10min；It is again heated to 20 DEG C, stirs 10min while heating, keep 20 DEG C of 10min, be cooled to room temperature, take out discarded electric power
Equipment, retain acid solution；
Step 5: split：Now discarded power equipment is split, is split as metal parts and non-metallic component；
Step 6: filtering alkaline solution and acid solution：What the alkaline solution and step 4 that filtration step three obtains respectively obtained
Acid solution, respectively obtain filtrate and sediment；
Step 7: the recycling of alkaline solution and acid solution：Alkaline solution and acid solution after recovery filtering, are weighed respectively
Newly it is used for step three and four；
Step 8: nonmetallic substance is split：It is 5*5cm that nonmetallic substance in step 5 is split as into size2Specification；
Step 9: nonmetallic substance melts：It is 5*5cm by the size obtained in step 82The nonmetallic of specification is placed in container
High-temperature fusion；
It is Step 9: modified：Zinc oxide, zinc dialkyl dithiophosphate and 4,4 '-two sulphur are added during step 9 melts
For morpholine.
Power equipment is discarded in the step 1 to waste gas using giant to be rinsed.
Alkaline solution in the step 3 is NaOH, KOH and CaOH2In one kind or any several mixture.
Acid solution in the step 4 is HCl, H2 SO4And HNO3In one kind or any several mixture.
Zinc oxide, the zinc dialkyl dithiophosphate and 4 added when modified in the step 9,4 '-dithiomorpholine
Mass ratio is 1:1:1.
Beneficial effect：Compared with prior art, the invention has the advantages that：
Discarded power equipment is rinsed by the present invention using giant first, the materials such as the soil on its surface is rinsed dry
Only, then soaked overnight in running water is placed on, be subsequently placed at the solubility on its surface in alkaline solution and acid solution
Material departs from so that metal is mutually disengaged with nonmetallic substance, and nonmetallic substance turns into after heat fusing and addition modifying agent can
With the rubber raw materials reused.The method that the present invention uses is simple and feasible, and the raw material of use is simple and is easy to get, alkaline solution and
It can also be reused after acid solution filtering, save the usage amount of raw material.
