Description

A raw water purifier

technical field

The utility model belongs to the technical field of water purifiers, in particular to a raw water purifier.

Background technique

Water purifiers, also called water purifiers and water purifiers, are water treatment equipment that perform in-depth filtration and purification of water quality according to the use requirements of raw water. It is mainly through the reverse osmosis membrane under the action of pressure, the raw liquid flows inside or outside the membrane, the solvent or small molecules in it can pass through the membrane, and become ultrafiltrate after collection, while the macromolecular substances and colloidal particles in it flow Bacteria, bacteria, etc. are trapped outside the membrane, and are taken away by the circulating raw solution to become a concentrated solution, so as to achieve the removal of impurities in the raw water and become purified water.

However, after the water purifier is used, separated substances and other impurities will gradually accumulate on the surface of the reverse osmosis membrane, which will cause pollution and blockage of the reverse osmosis membrane, thereby affecting the working effect of the ultrafiltration device. Under the action of pressure, the clean water flows out through the reverse osmosis membrane through the central axis, while the impurities are trapped on the surface of the reverse osmosis membrane. Under the action of water pressure, part of the raw water flow will pass through the hydrophobic network on the reverse osmosis membrane from top to bottom. Wash away the impurities and realize the function of decontamination while purifying water, but the flushing water only cleans the reverse osmosis membrane vertically along the direction of gravity from top to bottom, but lacks horizontal cleaning, resulting in many fine impurities still remaining The surface of the permeable membrane is not flushed enough, which is why the water purifier has to replace the filter cartridge or filter element every other year or so.
