Honestly Shen Wei's exact energy content after ep22 and what he does with it, I'm not sure of. I think it's a mixture, though, and that the mixture is unstable in a way that straight Haixing or Dixing energy isn't.
But I also think Ye Zun would have been able to digest Shen Wei eventually if Shen Wei hadn't detonated that energy.
Best guess for why Ye Zun can eat Haixing people but Shen Wei suffers from the energy exchange is something similar to jo_lasalle's - he's eating them not injecting them, and his body has time to break them down and convert them to usable energy- and his power is specifically the ability to do that. Unlike Shen Wei, who contaminated his system with a direct infusion of energy it wasn't meant to handle.
