HOLLOW FIBER MEMBRANE FILTER WITH SCREEN

PURPOSE: A hollow fiber membrane filtering device, a regenerating method thereof and a method for filtering condensate remove bulky foreign substances in condensate without installing extra pre-processor and a compressed-air facility, so that the structure of the filtering device is simple and the condensate is not thrown away to remove bulky foreign substances in the condensate, generating less waste water. CONSTITUTION: A hollow fiber membrane filtering device has a body (20), multiple filtration modules (30), a filtering screen (28) inside the body, an upper plate (26) and a lower plate. In the body, multiple inlet ports (21) are on the upper part, multiple enriched water vents (25) are on the lower part, and a treat water gateway (22) is in the side. The filtering screen is on the upper part of the multiple filtration modules. The upper plate (26) and the lower plate respectively fix the upper and the lower parts of the multiple filtration modules. When condensate in flowed in the multiple inlet ports passes through the filtering screen, bulky foreign substances in the condensate are firstly removed on the filtering screen, the condensate flows inside multiple hollow fiber membranes, and the condensate is filtered while being discharged from the inside to the outside of the hollow fiber membranes.
