The invention provides a novel
high pressure resistant, anti-
corrosion and high temperature resistant membrane shell, which comprises a shell, wherein two ends of the shell are connected with end covers; two axial ends of the outer side surface of the shell are respectively provided with a
branch pipe; a membrane element bracket is arranged on a position corresponding to each
branch pipe in the shell; each membrane element bracket comprises two circular ring groups which are fixedly connected through a rib plate; each circular ring group comprises at least two concentric circular rings. The invention simultaneously provides a preparation method for the novel
high pressure resistant, anti-
corrosion and high temperature resistant membrane shell and the preparation method thereof have the advantages of simple structure, easiness in
processing, low manufacture cost, large manufacture size range and high compatibility. When the
diameter is greater than 8 inches (203.2mm), the aspects including the
pressure resistance degree, the flow condition, the
mass transfer efficiency and the cost of the novel
high pressure resistant, anti-
corrosion and high temperature resistant membrane shell areall superior to that of the mainstream 8-inch membrane shell in the traditional market, a
space use ratio is improved, and a larger membrane area can be provided in
unit volume so as to obtain higherwater yield in the
unit volume.
