And all known structures, can't accomplish always efficient, low energy consumption, apparatus structure compact take up an area little, installation and maintenance are quick.
Summary of the invention
The some shortcomings that the purpose of this utility model is strict such as preliminary treatment in the above-mentioned prior art in order to overcome, existence moves the dead angle, difficulty is cleaned in lifting, operation energy consumption is high, the rate of recovery is low, and the micro-filtration or the ultrafiltration membrane separating device that provide a kind of external pressure low energy consumption to move, the utility model need not preliminary treatment when using, operation energy consumption is low, the rate of recovery is high, cleaning is simple, it is little to take up an area without operation dead angle, compact conformation, and installation and maintenance are quick.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of micro-filtration or ultrafiltration membrane separating device of external pressure low energy consumption operation, comprise tank body, the tank body loam cake, aerating system, stirring system, some hollow fiber filter membrane and filter membrane fixed head, it is characterized in that: some hollow fiber filter membrane are installed on the filter membrane fixed head and form filter membrane filtering system, filter membrane filtering system is installed between tank body and the tank body loam cake by upper-lower seal, at tank body lower part aerating system and stirring system are installed, tops is provided with and produces the mouth of a river on the tank body, tank body top is provided with concentrated water spout from tank body mouth 60mm～350mm place, tank base is provided with aeration opening, and 50mm above aeration opening～270mm place is provided with water inlet.
Be provided with the instrument mounting interface at the tank body loam cake from producing mouth of a river 50mm～220mm place.
Aerating system is installed in filter membrane filtering system lower end 0mm～300mm place.
Stirring system is installed in the aerating system below, be provided with from aerating system 55mm～130mm place, and the stirring system axis becomes respective angles to install with the tank body axis.
Described stirring system is the turbine stirring system, buys from market to obtain.Aerating system also is existing structure, buys from market to obtain.
The production method of external-compression type hollow fiber filter membrane is quoted " a kind of production method of hollow fiber film assembly " (publication number: 2010105568291) of Wuhan Aqucell Filter Membrane Technology Co., Ltd.'s application, and the filter membrane outside is without sleeve pipe, a kind of naked external-compression type hollow fiber filter membrane.Several filter membranes are installed in the tank body, and are independently individuality between each filter membrane, do not interfere with each other.Filter membrane curl on fixed head evenly distributes, and all has enough the cavity rate of large space super large to make the film silk that very large activity space be arranged between the filter membrane, can adapt to the former water of water quality very severe.
Stirring system becomes respective angles to install according to the axis with the tank body axis, when former water is full of tank body, stirring system starts, former water is along with the rotation of stirring system blade produces flowing of axial and radial direction, the film silk is along with current freely swing in the tank inner chamber of super large cavity rate simultaneously, need not aeration and can avoid equally pollutant in film silk surface sorption and deposition, will require strict preliminary treatment to remove fully.
Aerating system is between filter membrane filtering system and the stirring system, at filter membrane filtering system lower end 0mm～300mm place, from stirring system 55mm～130mm.Aerating system adopts nanometer aeration pipe, becomes the pawl type to distribute.Aerating system just starts operation when backwash, backwash timer internal pressure is lower, and aerating system adopts low-pressure aeration, greatly reduces operation energy consumption.
Whole tank body all adopts the SUS304 stainless steel, comprises tank body loam cake and tank body.
The positive-pressure type operational mode that the utility model adopts can realize the field module assembly unit, and installation and maintenance are quick, because its compact conformation, thereby its occupation of land is little.
The beneficial effects of the utility model are, not only the advantage with traditional inner pressed, external-compression type, suction type and aeration external pressure type hollow fiber film component is integrated in one: water distribution evenly, without the dead angle, require very low to raw water quality, outside the easy to clean, can also reduce operation energy consumption, improve the rate of recovery, reduce floor space and installation and maintenance are quick.
