Description
Technical field
The utility model belongs to the cleaning equipment to water treatment field, is specifically related to a kind of external pressure type hollow fiber membrane component captation, and the health rank is high.
Background technology
The world today is owing to environmental pollution, and water resource is constantly deficient, forces water technology fast-developing.Since the doughnut membrane technology have lot of advantages (comprise filter area big, be prone to reverse clean and cost lower etc.), therefore all be widely used in the fields such as water treatment, sewage disposal and middle water reuse of giving.
The structure of the hollow-fibre membrane in the doughnut membrane technology is a hollow tubular, and the length of hollow tube is far longer than its caliber, look just as a rhizoid, so hollow-fibre membrane is called the film silk by image.The tube wall of film silk is the macromolecule membrane with micro-aperture, and this is the filter membrane of filtration.Be motive force with outside energy or chemical potential difference when using, utilize film fiber tube wall filter membrane to filter, the solute that comes water is separated with solvent, be purified water outlet coming water.Because the film silk quantity that acts in the hollow-fibre membrane system is generally thousands of, damaged even therefore a small amount of film silk takes place, can not influence entire system yet and use, move more reliable.
The hollow-fibre membrane system is divided into external-compression type and inner pressed.Nearly all be inner pressed hollow-fibre membrane system giving water treatment field employed at present, the membrane module of this system has the pressure-bearing putamina of a hard, and the film tow that several (thousands of) hollow-fibre membrane film silk is formed is inserted in the putamina; And film silk end is connected with water inlet; The hollow tube chamber of film silk is communicated with water inlet, and stoste gets into the tube chamber of every film silk from the end of the outside film silk hollow tube chamber of putamina, drives through pressure differential; Radially seeing through film silk hollow tube tube wall from inside to outside becomes through liquid (clear water after promptly purifying); Get in the gap of film silk and putamina wall in the putamina, advancing/the delivery port outflow from the putamina is the water purification that obtains again; Concentrate is then stayed in the film silk hollow tube chamber, from the other end outflow of film silk hollow tube chamber.Need regularly recoil in the technology or use chemical cleaning solution to clean the hollow tube chamber of film silk, avoid concentrate (being polluter in the feedwater water preparation process) to stop up the film silk.It is thus clear that the corner or spot as yet untouched by a clean-up campaign is many in the putamina of inner pressed system, be difficult for thoroughly recoil or clean the film silk, current are prone to alluvial in putamina, polluted water, breed bacteria, particularly drinking water system water to water treatment field, bring water quality safety hidden danger easily.
And the container (envelope film container) that is used for encapsulating is all inserted at the two ends of the hollow-fibre membrane film tow of external-compression type system (being generally film tow in the form of sheets); Each end correspondence is inserted an envelope film container; Use hardenable resin material that film silk end is built to be fixed in the envelope film container and (be called the glue envelope); Again the end of each container is cut to expose the hollow tube chamber of film silk in the envelope film container, two envelope film containers are inserted in two captations, form a membrane module; Each hollow tube chamber that seals the film silk end in the film container is communicated with water stream channel in the corresponding captation; After assembling, captation and film silk all are immersed in the water body of pond, the water stream channel of captation is connected with suction pump/recoil or scavenging pump through pipeline.Produce the water stage, suction pump is opened, and aeration in the water body, the water in the pond get in the tube chamber after passing the tube wall filter membrane of each film silk in the film tow, get in the water stream channel of captation through film silk end along tube chamber, get in the follow-up clear water reserviors through pipeline again.Accumulate in behind particulate matter in the water body (be pollutant, comprise bacterium etc.) the tunicle fiber tube wall membrane retention in the film fiber tube wall outside and the pond water body, the film silk is constantly impacted to take away the pollutant that the film fiber tube wall outside is built up by current and air-flow.The film silk itself is to have the outer press mold silk of the enhancement mode that strengthens structure, can hold out against the repeated stock of current air-flow.And at recoil stage or wash phase, water (flow) direction is opposite.
Than the inner pressed system; The external-compression type system is immersed in the water body owing to the film silk; Film silk space outerpace is big; The corner or spot as yet untouched by a clean-up campaign is few, so the wholesomeness of the captation that is communicated with the film silk in the external-compression type system membranes assembly is the vitals of restriction external-compression type system water quality safety, health in giving water treatment field.
Summary of the invention
The utility model provides a kind of external pressure type hollow fiber membrane component captation of health, can breed bacteria, and can residual harmful substance.
