The specific embodiment
Referring to Fig. 1 to 4, the film filter of the utility model double filtration (100 or 200) comprises at least one filter element (101), and two are drawn sap cavity (120), and two are drawn sap cavity shell (122) and at least one and draw the production fluid pipe (121) that sap cavity (122) communicates; It is characterized in that wherein said filter element (101) comprises many capillaries film (110); At least one screen cloth crossed filter ruffle (116) and said many capillaries film (110) and screen cloth crossed filter ruffle (116) two ends and be cast in two LIFTs (140) together respectively; Said many capillaries film (110) is crossed filter ruffle (116) by screen cloth and is wrapped up fully between two said LIFTs (140); Said many capillaries film (110) two ends are all open; And with said sap cavity (120) UNICOM of drawing, simultaneously said many capillaries film (110) outside and screen cloth are crossed in the filter ruffle (116) outside and are all drawn sap cavity (120) isolation with said.
Referring to Fig. 1 and Fig. 2; The film filter (100) of first kind of double filtration of the utility model is characterized in that at least one filter element (101) realizes that through two assembly LIFTs (141) said many capillaries films (110) outside and screen cloth cross in the filter ruffle (116) outside and all draw sap cavity (120) isolation with said.
