This utility model discloses an adjustable membrane material prestress fixing clamp and system, relating to the field of clamp technology. It solves the problem that existing prestressed membrane materials, fixed with edge bolts or rivets, are difficult to control, especially for planar membrane materials requiring high prestress values. An embodiment of this utility model discloses an adjustable membrane material prestress fixing clamp, including a clamp body with a membrane material pulling groove and a locking groove arranged opposite to each other; it also includes a pulling member that passes through the membrane material pulling groove and can move freely within it, and several adjustable locking members with adjustable locking positions, the adjustable locking members being disposed within and slidably connected to the locking groove.

This invention discloses a planar membrane mass transfer internal component, a collection tower, and a collection system based on sound field enhancement. The planar membrane mass transfer internal component includes several vertically arranged resonant composite plates and a support assembly for supporting the resonant composite plates. The resonant composite plates are layered structures with double-sided mass transfer, comprising, from the inside out, a piezoelectric transducer array layer, an acoustic impedance matching layer, and a hydrophilic microporous mass transfer layer. The piezoelectric transducer array layer is electrically connected to a power supply to generate high-frequency mechanical vibration, thereby forming a high-frequency sound field. The support assembly includes several limiting grooves located above and below the resonant composite plates, and a frame for fixing the limiting grooves. The resonant composite plates are floatingly installed within the limiting grooves, with their upper and lower ends forming a limiting fit with the limiting grooves. This invention significantly improves mass transfer efficiency by disrupting the boundary layer of high-viscosity liquid films at the microscale using active sound field technology, and solves the problem of fixing and damping piezoelectrically brittle components in industrial towers by employing a floating installation structure.
