The application provides a polyaniline-zinc ion battery with continuous replacement of electrolyte, which comprises a first liquid tank, an electric pile and a second liquid tank which are in communication with each other, the first liquid tank and the second liquid tank respectively store high-concentration and low-concentration zinc salt aqueous solutions, the electric pile comprises a polyaniline active layer, a first porous separator and a zinc layer which are adjacent in sequence, the polyaniline active layer is close to the first liquid tank, and the zinc layer is close to the second liquid tank. The polyaniline-zinc ion battery does not need an ion exchange membrane, and the electrolyte in the electric pile can be continuously replaced during charging and discharging, so that the concentration difference polarization is eliminated, the chemical equilibrium of the electrochemical reaction is promoted to move in a favorable direction, the charging and discharging voltage difference of the battery is reduced, the energy efficiency is improved, and the service life is longer.

The invention relates to the field of flue gas purification product resource utilization and coal rock gas yield increase and injection increase, in particular to an alkaline desulfurization and denitrification agent and application thereof in coupling of a flue gas resource desulfurization and denitrification process and coal rock gas acidification yield increase and injection increase. The invention provides an alkaline desulfurization and denitrification agent, the alkaline desulfurization and denitrification agent contains camellia saponin and a crown ether ring structure, sulfuric acid, nitric acid and fluoboric acid mixed salt of the alkaline desulfurization and denitrification agent is generated after desulfurization and denitrification, the mixed salt is used for coal rock gas acidification, flue gas desulfurization and denitrification waste liquid can be recycled, and the desulfurization and denitrification cost can be recovered; in addition, a bis-imidazoline alkaline desulfurization and denitrification agent containing crown ether and camellia saponin is combined with plasma irradiation oxidation to perform desulfurization and denitrification on the flue gas, and the desulfurization and denitrification waste liquid is used for reservoir transformation, so that environmental pollution can be better treated, one agent can be used for multiple purposes, the acidification cost of the carbonate reservoir is reduced, and slow acidification and diverted acidification are realized at the same time.
