It should be noted that, the invention is a gas distribution device, and when in specific work,

1. compressed air is introduced into the upright post 2 through an air guide pipe by an air compressor, high-pressure gas is introduced into an air inlet 10 of a one-inlet two-outlet ball valve through a hollow pipe in the upright post 2, at the moment, a left air outlet 7 is in a maximum flow ventilation state, the high-pressure gas is introduced into an injection pipe I13 which is positioned at the lower part of the impeller 15 and extends upwards according to a right-hand spiral through the left air outlet 7, the high-pressure gas is sprayed out and acts on one side of the horn-shaped impeller 15, the outer cylinder wall 4 is pushed to slowly start and circularly move along the upper gas distribution cover 6 and the lower sealing plate 16 through a reaction force, and then the stirring paddle 3 is driven to stir water areas around the base 1, so that the use;
