Positive pressure air supply elevator ventilation system and elevator

The utility model belongs to the field of elevator ventilation, and provides an elevator ventilation system with positive pressure air supply and an elevator. The problems that an existing ventilationscheme is poor in ventilation effect and has public health safety risks are solved, it can be guaranteed that enough fresh air enters an elevator, and the ventilation effect is good. The elevator ventilation system comprises a positive pressure air feeder and a positive pressure air supply pipeline. The positive pressure air feeder is arranged at the position, communicated with outdoor fresh air,of a building above an elevator shaft. The positive-pressure air feeder is connected with the upper end of the positive-pressure air feeding pipeline, the positive-pressure air feeding pipeline is arranged in the elevator shaft, and the lower end of the positive-pressure air feeding pipeline directly feeds outdoor fresh air conveyed by the positive-pressure air feeder into the elevator shaft; thepositive pressure air supp
