Water purifier with multi-stage filtration
Technical Field
The utility model belongs to the technical field of water treatment, concretely relates to purifier with multiple stage filtration.
Background
The hardness of water is mainly composed of cations in water, such as calcium (Ca2+), magnesium (Mg2+) ions. When the hardness of water is higher, if do not carry out the softening and handle very easy scale deposit when directly passing through the cooling tower coil pipe to influence the heat exchange efficiency of cooling tower, consequently generally can use the water softener to handle industrial raw water. The principle of the water softener is as follows: when raw water containing hardness components passes through the resin layer in the water softener, calcium (Ca2+) and magnesium (Mg2+) ions in the water are exchanged and adsorbed by the resin, and sodium (Na +) ions are released by the same mass, so that the water flowing out of the water softener is softened water with the hardness ions removed. When the resin adsorbing calcium (Ca2+) and magnesium (Mg2+) ions reaches a certain degree, the exchange resin in the water softener fails, the water softener automatically performs regeneration work of the failed resin according to a preset program, and the failed resin is restored to the sodium resin again through the failed resin by using a NaCl solution with higher concentration.
Water softeners are generally equipped with a salt tank for dissolving NaCl, and an excess amount of NaCl is added to the salt tank to make the solution a saturated NaCl solution (i.e., saturated brine). The water softener multi-way valve sucks saturated salt water in the salt tank into the water softener to regenerate the failure resin. For example, CN204873943U discloses a water softener, which comprises a softener and a salt tank, wherein the salt tank is composed of a tank body and a salt well cover, the side surface of the tank body is provided with a salt pipe orifice and an overflow orifice, and the salt pipe orifice of the salt tank is connected with a salt suction orifice on a softening valve head through a salt suction hose; the salt well and the regenerated salt box partition board are arranged in the box body, the salt well is inserted into a salt well inserting hole of the regenerated salt box partition board, a plurality of partition board supporting legs are arranged on the regenerated salt box partition board, a salt absorption filter is arranged in the salt well, a salt absorption pipe connecting port is arranged at the upper end of the salt well, and the salt well is connected with a salt absorption hose through the salt absorption pipe connecting port. The softener is connected with the salt well of the salt box through a salt absorption port on the softening valve, and the regeneration step is as follows: salt absorption, water supplement, back flushing and normal flushing, and sewage after salt absorption and flushing is discharged from a sewage discharge outlet.
At present, most of the salt special for large-particle soft water is used on a water softener because common refined industrial salt has more impurities, long dissolving time, easy salt bridge formation or salt particle formation and difficult cleaning; if the existing water softener adopts refined industrial salt, the salt absorption pipe is easy to absorb impurities and salt particles, block the salt absorption valve and even pollute resin and softened water. Due to the existence of impurities, the salt plate is easy to be hardened around and difficult to take out, so that the optimized design is necessary; in addition, most of the existing salt plates are flat plates, and the contact surface of a solute and a solvent can be enlarged so as to facilitate rapid dissolution and achieve saturation, so that the operation efficiency is improved.
In addition, as the Chinese invention patent, CN201621402071.5, a water softener salt box and a water softener disclose a sealed salt plate, and the contact area is objectively increased by arranging filter caps above and below the salt plate.
