Problems solved by technology

Although the invention adds spoilers, there is still a large gap between the linear velocity of the surface of the ceramic membrane near the center and the linear velocity of the outer edge, the spoiler effect is limited, and the dense phase material of the ceramic membrane placed horizontally is subjected to gravity during use. The impression will still be deposited on the surface of the ceramic membrane with a high probability, causing secondary pollution on the surface of the membrane, reducing the permeability and service life of the membrane
