Description
[ technical field ] A method for producing a semiconductor device
The utility model relates to a filtration equipment technical field, in particular to big flux doublestage filter core of strabismus for solid particle and impurity in the filtration aquatic.
[ background of the invention ]
The water filtration is widely applied to the industries of petrochemical industry, coal chemical industry, medicine, food, electronics and the like, and mainly removes impurities and unnecessary components in materials through filtration, so that the materials containing the impurities are clean again and are reused in life and production. In water filtration treatment systems, reverse osmosis filtration is essential. Reverse osmosis membranes have high requirements on the quality of inlet water, particularly the content and the size of particle impurities, and therefore, in order to ensure the reverse osmosis filtering effect and the service life of the reverse osmosis membranes in practical application, security filters need to be arranged before reverse osmosis. The security filter is used for removing large-particle impurities in the wastewater in advance, and the particle size of the impurities in the wastewater treated by the security filter is less than or equal to 10 mu m, so that the normal use of the subsequent reverse osmosis membrane can be ensured.
The cartridge filter adopts a high-flux filter element, the filtering precision is usually 5 mu m, the cartridge filter belongs to an easily-consumed product, and the replacement period of the cartridge filter element is 5-15 days as short as 2-3 months as long as the water quality of the incoming water is different. Particularly, coal chemical industry and chemical industry enterprises in northwest regions have poor water quality and lack of local water resources, so that the quality of produced wastewater is generally poor, the replacement period of the filter elements of the security filters of the enterprises is short, generally about 7 days, and the replaced waste filter elements can only be used for solid waste treatment. Therefore, the operating cost pressure of the security filter is very high for enterprises with large wastewater treatment capacity (tens of thousands of parties/day).
At present, most of cartridge filter elements are straight-pleat single-stage filter elements, namely, the filter elements only have one-stage filter materials, and the filter materials are formed by folding straight pleats. The straight-pleat single-stage filter element has the advantages of fixed flow area and single filtering precision, is only suitable for the condition of stable quality of incoming water, and particularly can block membranes quickly when the quality of the incoming water is poor and the particle size of impurities is increased, so that the replacement period of the filter element is shortened greatly.
However, the outer diameter of the filter element cannot achieve satisfactory effect due to the limitation of the straight pleat folding mode, the reason is that when the outer diameter is increased, the straight pleat L is increased, when the filter element structure is manufactured, the α angle is increased, the gaps between the pleats are increased, the straight pleat folding filter material is looser in the inner cylinder and the outer cylinder, the filter material strength is lower, the instability of fluid is caused by the impact of water flow, the filter element is stressed unevenly, the local folding filter material or the filter element is deformed possibly to lose the filtering performance, so the limitation of the straight pleat folding mode is applied, the inner diameter and the outer diameter of the filter element on the market are basically 3 '/6', the filtering area is limited, and fig. 1 is a schematic diagram of the straight pleat filter element structure commonly used on the market at present.
Patent CN207187243U provides a slant fold water filter element, which changes the straight fold filter form into slant fold filter form, and increases the filter area and performance of the filter element. The utility model discloses a slant pleat filter core that provides has following advantage:
(1) the specific surface area of the filter material is effectively increased, and the angle of the inclined pleat can be adjusted according to the inner diameter and the outer diameter of the filter element, so that a larger filter area can be obtained even if the volume is smaller;
(2) the filter has the advantages that the structure is simple, the maintenance is simple and convenient, the reliability is high, the pleats are tightly rounded, gaps among filter materials cannot be generated, and pollutants can be prevented from leaking out of the filter materials to the maximum extent;
(3) the filter element has strong pressure resistance and good stability, and can enhance the strength of the filter element while maintaining the corresponding filter area.
However, the single-stage pleated filter element has single filtering precision and limited filtering flow area, and thus the requirements of the existing cartridge filter on the water filtering filter element cannot be met.
