Tubular membrane module

The utility model relates to a tubular membrane module belongs to the membrane separation and equips technical field. Problem to the atress of film element among big filling quantity's the tubular membrane module is easily broken is improved, realizes through the internally mounted bracing piece. Including first head, second head, barrel, establish first head and second head respectively in the both sides of barrel, between first head and the barrel, all be provided with the flower disc between second head and the barrel, be provided with the opening on the flower disc, being provided with the export of first penetrant on the barrel, setting up the feed liquid import on the first head, set up the feed liquid export on the second head, still be provided with an at least spinal branch vaulting pole in the barrel, the both ends of bracing piece are fixed in respectively on the flower disc at both ends. The utility model provides a tubular membrane module can improve the installation volume of the tubular membrane in same membrane module, and improve equipment's loading density reduces equipment investment cost, is suitable for very much during big batch feed liquid handles the engineering, and the installation stability of film element obtains improving.
