Example Embodiment
[0026] Example 1
[0027] Put 100g of waste transformer in a small reactor, heat it at 80°C for one hour, then cool it to room temperature and leave it for 24 hours, and filter it with a filter press to remove most of the mechanical impurities to obtain component oil A 1 ;to A 1 Add 1 g of concentrated sulfuric acid to the mixture and stir well to obtain B 1 ; to B 1 Add sodium hydroxide with a concentration of 3%, adjust the pH to 6.3, and obtain C 1 ;to C 1 Add 5g of desulfurizer to it, stir it evenly, filter it with a filter press, and then pass it through the acrylic resin to obtain D 1 ; finally put D 1 After passing through molecular sieves, light yellow regenerated transformer oil is obtained.
Example Embodiment
[0028] Example 2
[0029] Put 100g waste transformer in a small reactor, heat it at 90°C for one hour, then cool it to room temperature and leave it for 24 hours, filter it with a filter press, remove most of the mechanical impurities, and obtain component oil A 2 ;to A 2 Add 5g of concentrated sulfuric acid to it, stir well, get B 2 ; to B 2 Add sodium hydroxide with a concentration of 5%, adjust the pH to 7.2, and obtain C 2 ;to C 2 Add 10g of desulfurizer to it, stir it evenly, filter it with a filter press, and then pass it through the phenolic resin to obtain D 2 ; finally put D 2 After passing through molecular sieves, light yellow regenerated transformer oil is obtained.
Example Embodiment
[0030] Example 3
[0031] Put 100g waste transformer in a small reactor, heat it at 90°C for one hour, then cool it to room temperature and leave it for 24 hours, filter it with a filter press, remove most of the mechanical impurities, and obtain component oil A 3 ;to A 3 Add 3 g of concentrated sulfuric acid to the mixture, stir evenly to obtain B 3 ; to B 3 Add sodium hydroxide with a concentration of 5%, adjust the pH to 7.5, and obtain C 3 ;to C 3 Add 12g of desulfurizer to it, stir it evenly, filter it with a filter press, and then pass it through phenolic resin and acrylic resin to obtain D 3 ; finally put D 3 After passing through molecular sieves, light yellow regenerated transformer oil is obtained.
