Description
Technical Field
The invention relates to the technical field of filtration, in particular to a filtering device and a water purifier.
Background
The current water purifier mainly comprises:
1. a PP cotton filter element water purifier: the single-tube water purifier with various PP cotton filter elements is simple in structure and convenient to install, but the filter elements are easy to block, the replacement frequency is high, the filtering precision is not high, and the single-tube water purifier is only used for primary filtering of water and cannot be directly drunk.
2. The composite sintered active carbon water purifier comprises: the main filter medium is an activated carbon rod. The activated carbon rod is generally formed by sintering activated carbon powder with different particle sizes and a bonding material at a high temperature.
The method is characterized in that: due to the porous structure of the activated carbon powder (according to estimation, the specific surface area of 3-5 g of the activated carbon powder is equivalent to the size of a standard American football court), the activated carbon rod after being fired is very compact, has high removal efficiency on pollutants such as peculiar smell, residual chlorine, volatile organic matters and the like in tap water, can filter spore cysts even according to the American NSF53 standard by part of activated carbon rods produced by manufacturers, can retain mineral substances in water, and does not need to use extra filtering media such as microfiltration, ultrafiltration and the like.
In addition, in the firing process of the activated carbon rod, other filter media can be added through a special process formula, so that the activated carbon rod is compounded with more functions of removing indexes such as volatile organic compound pollutants (VOC), heavy metals and the like.
Due to the excellent performance of the composite sintered activated carbon rod, the product can be directly used for occasions with high filtering requirements such as drinking, cooking and the like.
However, the product has high manufacturing cost, and the activated carbon rod filter element is easy to block and needs to be replaced frequently.
3. RO reverse osmosis water purification machine: the water purifier can completely remove harmful substances in water and simultaneously remove mineral substances in the water, and the purified water is pure water. The water is not at its working pressure and therefore requires a booster pump, with the aid of electricity and pressure. The method has the great disadvantage that the waste water is more, and about 50 percent of the waste water is generally filtered. Its advantages are high cleaning cost and low water output.
4. The composite filtering design of the imported non-woven fabric, the Japanese ultrafiltration membrane and the imported coconut shell activated carbon can effectively filter bacteria in water and various harmful substances such as chlorine, pathogenic microorganisms and the like, and the external kettle can also avoid drinking water with heavy metals exceeding the standard. The purification effect of direct drinking of tap water is ensured to be realized, the integrated design is adopted, secondary pollution can be prevented, materials are imported, and the manufacturing cost is high.
5. An ultrafiltration machine: the ultrafiltration water purifier can effectively remove silt, suspended matters, rust, bacteria, colloid, macromolecular organic matters and the like in water, and can effectively retain some beneficial mineral substances, trace elements and the like. Its advantages are long service life of filter core, high output of water, no need of pressurization, and low cost. The major disadvantage is the complete lack of removal of heavy metals and organic pollutants.
6. A ceramic filtering water purifier. The water purifier adopts the plug-in ceramic filter element, has large water yield, meets the requirement of water for kitchens, and has the membrane pores of the double-control membrane ceramic filter element with the highest precision of 0.1 mu m smaller than bacteria, so that the bacteria are completely isolated outside the filter element, but water can pass through the filter element, and beneficial mineral substances and trace elements in the water are reserved. Meanwhile, the water purifier does not produce secondary pollution in the using process, is not afraid of blockage, and realizes the terminal water purification function. The disadvantages are short service life of the filter element and small water yield.
