The invention relates to a
gasoline steam purification device utilizing an electric
magnetism-generating transmission principle. The
gasoline steam purification device utilizing the electric
magnetism-generating transmission principle comprises a
volute, an
impeller and a shell. The upper end of the shell is connected with the
volute. A cylindrical partition plate is arranged in the middle of the inner bottom of the shell. A
stator is installed inside the cylindrical partition plate. The magnetic
impeller arranged coaxially with the
stator is installed in the position, above the cylindrical partition plate, of the
volute in a rotating mode. An air intake
pipe is vertically arranged in the position, corresponding to the center of the magnetic
impeller, of the upper end of the volute. An air
exhaust pipe is arranged on the side wall of the volute in the tangent direction of the magnetic impeller. A bottom cover is installed at the bottom of the shell. A PCB is installed between the bottom cover and the shell. A
magnetic field is generated inside the
gasoline steam purification device through the electric
magnetism-generating principle, the magnetic impeller is driven to rotate by the
magnetic field, and accordingly
pressure difference is formed; and oil steam collected by a carbon tank is fed into an air intake manifold and prevented from being exhausted into air, and the requirement for emission reduction is met accordingly.
