多面空心球中部沿整个周长有一条加固环，环上、下部各有12条球瓣，沿中心轴呈放射形布置。该球气速高、叶片大、阻力小；比表面积大，可以充分解决气液交换，广泛应用于除氟、除氧气、除二氧化碳器，接触反应器。

Multi-faceted hollow ball along the entire perimeter of the middle there is a reinforcement ring, ring, the lower part of each ball valve 12, along the central axis showed radial arrangement. The gas velocity the ball high, leaves large, the resistance is small; large surface area that can adequately address the air-fluid exchange, widely used in fluoride removal, in addition to oxygen, in addition to carbon dioxide devices, contact reactor.
