Abstract

Disclosed are a magnetic regulation and control ion salt-difference power generation device and method based on waste heat utilization.When the magnetic regulation and control ion salt-difference power generation device is in a working state, a storage battery stores the electric energy generated by ion salt-difference power generation and supplies the electric motor and electronic devices, the electronic devices supply the waste heat generated by work to the magnetic regulation and control ion salt-difference power generation device for recycling, and the electric motor controls the movement of the outer magnetic pole to change the magnetic field strength and direction to drive the movement of the magnetic nanoparticles, the flow rate caused by the movement and the inherent high thermal conductivity of the magnetic nanoparticles can strengthen heat exchange and power generation; when the magnetic regulation and control ion salt-difference power generation device is in a non-working state, the electric motor controls the outer magnetic pole to adhere to the high-salt storage pool to provide a larger magnetic field, so that the magnetic nanoparticles of the high-salt storage pool adhere to the nano-selective membrane to hinder the diffusion of ions, and the self-discharge problem of the magnetic regulation and control ion salt-difference power generation device is solved.
