Water purifier is in casing.
Technical principle and the course of work:
Running water returns to the top of filtration core by the lower end after backwash valve by central tube, is then supplied by outlet pipe First order filter, second level filter and the filtering of third level filter, then after entering water electromagnetic valve and booster pump will be filtered Water feeding fourth stage filter in, because in fourth stage filter, built with RO films, the water after membrane filtration passes through against the current Valve and high-voltage switch gear are reached in level V filter, through a filtration, purification, not over the water of RO films from fourth stage filter Wastewater outlet returned to via waste water magnetic valve and waste water inlet pipe in filtration core, proceed filtering and purification, so that real Existing waste water recycling, so the discharge without waste water.
The effect of booster pump is to be stored by the water purification after RO films in pressure measuring cylinder, is reduced when opening water tap with two outlet pressure When, the water purification in pressure measuring cylinder is supplemented by level V filter, meets the flow that water tap with two outlet discharges water.
Provided with fore filter, backwash valve water side and reverse osmosis water purifier first order filter on fore filter Second level filter and the connection of third level filter;Installed on the water pipe of third level filter water side 24 volts of entering water electromagnetic valves and Booster water pump one, squeezes into water in fourth stage reverse osmosis (RO) film by booster pump, and the hydrone less than 0.0001 micron is going out Water end (W.E.) is provided with current valve, connects threeway;One end connection enters pressure pot, and the other end connects the water inlet end of level V filter, the The water side of Pyatyi filter is connected with bleeder cock;In addition set in fourth stage reverse osmosis (RO) film water side second delivery port with Wastewater valve is connected, and protection RO film backwashes, waste water enters specific function fore filter, reaches reverse osmosis water purifier zero-emission, It is controlled automatically at for complete machine before first order filter and sets low tension switch, high-voltage switch gear is set after current valve, 24 volts is set before water pump Transformer, complete machine connects to be formed by circuit board automatically controls all-in-one.
Counter-infiltration function water purifier, water inlet end and fore filter backwash valve, water side connection are provided with case;Waste water In the waste water inlet of pipe insertion fore filter.
Complete machine formation result of the reverse osmosis water purifier without wastewater zero discharge, in order to ensure in water quality, fore filter High more than 300MM activated zeolites and activated carbon are put into, allows running water to be directly entered the zeolite and activity from backwash valve water inlet The bottom of charcoal, by activated zeolite and charcoal-stripped, ion exchangeable, catalytic, ion selectivity, acid resistance, more into Divide property and very high bioactivity and mithridatism, the active oxygen in top is filled into from down and is formed, plus electrolyzer, reactive hydrogen is generated, Combined with the active oxygen in water, form the plain water of water and enter water purifier, further filtering produces the plain water drinking water of high-quality water.
The waste water that water purifier is produced enters in the filtration core of activated zeolite and activated carbon, by adsorptivity, ion exchangeable, Catalytic, ion selectivity, acid resistance, the effect of multicomponent and very high bioactivity and mithridatism, with after filtering from Water is mixed, and produces stable hydrone.
To feed intake conveniently, charging aperture is set on the top of fore filter.
Electrolyzer is installed in the charging aperture of fore filter, by producing activation hydrogen and active oxygen to water electrolysis, and not Change water temperature;
Electric-controlled plate, the control for water purifier are housed on water purifier.Set control module controls height respectively on electric-controlled plate Compress switch, low tension switch, electrolyzer, entering water electromagnetic valve, booster pump and waste water magnetic valve and power supply.
Feature:
Due to can effectively adsorb non-water substance built with zeolite and activated carbon, especially zeolite in fore filter, so By the water of prefilter, most of particulate matter is filtered and adsorbed, and mitigates the burden of next step filtering.In fore filter Under effect, purification waste water is returned in fore filter, is carried out repetitive decontamination, is improved the utilization rate of water, work as fore filter After adsorbate saturation, the filtering material for being backwashed or more being renewed is continuing with.
Due to being equipped with electrolyzer on fore filter, the water after electrolyzer can filter fore filter carries out electricity Solution, produces oxonium ion after electrolysis, is dissolved in the water to form active oxygen, and hydrogen ion is water insoluble, but with the filtering step by step of dampening, When by water tap with two outlet, the Shui Sushui containing reactive hydrogen is just produced, it is favourable to health.
Using fore filter can carry out six grades filtering, can remove impurities in water, heavy metal, industrial pollutants and Odor profiles material, and it is easy to cleaning, effect is kept, usage cycles are long.
