1. , a kind of gas is carried the internal circulating membrane filter, it is characterized in that comprising many hollow-fibre membranes or capillary-pipe film or tubular membrane, and two are drawn sap cavity up and down, one shell, an aerator, at least one is positioned at the outer comb of the gas-liquid of drawing the sap cavity top, a liquid reflux channel, two LIFTs up and down;

  • Wherein the top of many hollow-fibre membranes or capillary-pipe film or tubular membrane and bottom are packaged together by two LIFTs up and down respectively, and the tube chamber of every hollow-fibre membrane or capillary-pipe film or tubular membrane draws sap cavity and bottom by top and bottom and top and draws sap cavity and be communicated with;

    Wherein shell by clip with draw sap cavity up and down and be connected;

    Wherein have at least one production fluid pipe on the shell wall, the chamber that draws water down is provided with at least one feed tube and at least one air inlet pipe;

    Wherein aerator is located at down to draw in the sap cavity and is connected with air inlet pipe;

    Wherein the aerator centre does not have gas to expose;

    Wherein liquid reflux channel is one to be positioned at the liquid return tube of film filter longitudinal center, liquid return tube upper end with on draw sap cavity and be communicated with, the lower end extends aerator and does not sentence apart from aerator center 10-100 millimeter above the aeration center and guarantee that the gas that aerator exposes can not enter liquid return tube.
