When liquid flows downward packing’s surface to become liquid droplet,these droplet fall down the next packing’s surface to form interflow.After that, when liquid droplet contacts with the rising gas, material was be transferred.

Gas & liquid’s contacting basically principle is collision type surface’s continuously update.Metal cascade mini ring’s two end’s round turnup and large wall’s area will promote liquid’s continuously interflow and shunt to achieve surface’s update. Therefore, it can be regarded as one high gas-liquid contacting efficiency metal random packing.
