Energy-saving water purifier with backwashing function

Abstract

The invention discloses an energy-saving water purifier with a backwashing function. The energy-saving water purifier comprises a PP cotton filter element 1, a front activated carbon filter element 2, an ultrafiltration membrane filter element 3, a nanofiltration membrane filter element 4, a rear activated carbon filter element 5, a backwashing part 6, a fixed frame part 7, a water outlet part 8, a connecting pipe 9 and a blow-down valve 10; the backwashing part 6 comprises a booster pump 61, a three-way connected ball valve 62, a water storage pressure barrel 63 and a fixing nut 64; the fixed frame part 7 comprises a fixed bracket 71 and a fixed frame 72; and the water outlet part 8 comprises a concentrated wastewater / sewage outlet 81, a domestic water outlet pipe valve 82, a domestic water outlet pipe 83 and a drinking water outlet 84. Compared with a traditional water purifier, the water purifier has the advantages that the energy consumption can be effectively reduced, the service life of the membrane is prolonged, the use cost of water purification is reduced, ions in water can be selectively removed, and the backwashing function is achieved; the integrated design is adopted, the use space is saved, maintenance is convenient, the operation and maintenance cost is low, the effluent quality is stable, and the service life is long.

Description

technical field [0001] The invention relates to water treatment equipment, in particular to an energy-saving water purifier with backwashing function. Background technique [0002] At present, most of the water purifiers on the market do not have a backwash function, so they are prone to scale during use and cause pollution by clogging the membrane; a few water purifiers with a backwash function need to switch the pipe connection during backwash, so After cleaning, there is likely to be unremoved residual gas in the equipment, which will cause the equipment to rapidly increase the pressure during continuous operation, and form an air hammer to damage the membrane. Therefore, the quality of the effluent gradually deteriorates with the increase of the use time, and it is necessary to simplify the operation of backwashing and achieve efficient flushing. [0003] In addition, the water purifiers on the market often have the problems of high energy consumption, high operation an...
