AI Technical Summary
Existing membrane modules suffer from reduced strength and shortened service life due to the lack of space for the membrane tubes to stretch under temperature changes.
A retractable membrane shell structure is designed to release the membrane tube's extension space by utilizing the gap between the left and right membrane shells, thus avoiding membrane tube twisting. The membrane tube is made of polymer material and connected by clamps.
It effectively reduces the damage rate of membrane modules, extends their service life, and protects the membrane tube from twisting and breakage caused by space constraints.
