The present invention discloses a flow channel assembly for a membrane element, the flow channel assembly comprises: a flow channel element, the flow channel element is concaved inwards to form a plurality of concave structures and is convex outwards to form a plurality of convex structures, and the plurality of concave structures and the plurality of convex structures are distributed in a staggered manner; the flow channel element comprises a water inlet section, a transition section and a water outlet section in the first direction, and the density of the multiple concave structures and the density of the multiple convex structures are gradually increased in sequence along the water inlet section, the transition section and the water outlet section. Through the gradient design that the density of the concave-convex structures of the water inlet section, the transition section and the water outlet section is gradually increased, water flow resistance at the water inlet end is reduced, pressure loss is reduced, and it is guaranteed that water flow enters rapidly and stably; the transition section realizes stable transition of water flow from a low-resistance state to a high-turbulence state and prevents the water flow from impacting the surface of the membrane; the high-density concave-convex structure at the water outlet end generates strong turbulence to effectively scour a concentration polarization layer on the surface of the membrane, low resistance and high turbulence are both considered, the scale deposition risk is reduced, and the service life of the membrane element is prolonged.

And the inlets and the outlets of the adjacent heat exchange units are communicated.

This invention relates to the field of micro-power generation technology, and more particularly to an integrated micro permanent magnet direct-drive generator. The generator includes: a duct housing, a turbine, a permanent magnet power generation unit, a flow field monitoring module, and a control unit. This invention designs the inner wall of the duct as a composite curved surface with a specific helical waveform and axial contraction, precisely matching its key shape parameters with the aerodynamic design point of the turbine. This allows the airflow to be accelerated by the Venturi effect as it passes through the duct, and further endowed with tangential momentum consistent with the turbine's rotation direction by a controllable helical bulge structure. Simultaneously, based on real-time monitoring of the outlet swirl intensity and load closed-loop control, the optimal aerodynamic matching state is dynamically maintained. Furthermore, monitoring of characteristic pressure distribution enables early warning of duct performance degradation, effectively solving the problem of reduced power generation efficiency caused by mutual interference of airflows due to the use of multiple parallel independent flow guiding mechanisms.

The module comprises a shell assembly, a plurality of gas inlet joints, a trapped gas outlet pipe and a permeated gas outlet pipe, the shell assembly is a cylindrical hollow shell, the interior of the shell assembly is divided into at least three independent channels in the axial direction, and a plurality of turbulent flow protrusions are arranged on the inner wall of each channel. Inclined air inlet holes which are in one-to-one correspondence with the channels and are connected and communicated with the air inlet joint are formed in one end of the side wall of the shell; the other end of the side wall is provided with a trapped gas outlet hole which is correspondingly connected and communicated with the trapped gas outlet pipe; a permeable gas gathering hole is formed in the head of one end of the shell and is communicated with a permeable gas outlet pipe. The module adopts a cross-flow multi-channel shell, is reasonable in structural design, can realize uniform distribution of airflow, remarkably reduces airflow dead zones among membrane filament bundles, and improves the effective utilization rate and mass transfer efficiency of membrane filaments. The device is suitable for various efficient and stable gas separation scenes such as industrial gas separation, natural gas purification, fuel cell tail gas treatment, chemical tail gas recovery and biogas purification.
