Description
Technical field
This utility model is related to water purifier, more particularly to a kind of water purifier of pure water backflow backwash ultrafilter membrane.
Background technology
China most cities with III class surface water, rural area mainly with IV class subsoil water as drinking water source, with dirt
The aggravation of dye, two worms（Giardia lamblia stiles, Cryptosporidium）, blue-green alge, heavy metals exceeding standard the problems such as, seriously threaten town and country and drink
Water security.Therefore, surface water, subsoil water have to pass through purification and could use as drinking water.Present domestic, commercial potable water
Reason technological core is mainly membrane filtration technique.Ultrafiltration apparatus can filter out larger molecular organicses in water, colloid and float.It is super
Filter device core technology adopts a kind of advanced Ultra filtration membrane technology, and the solvent contained in feed liquid and various little solutes are from height
Binder liquid side reaches low-pressure side through filter membrane, so as to obtain permeate or referred to as ultrafiltrate.Ultrafiltration membrane micropore is up to 0.01 micron
Hereinafter, under microgranule, colloid, antibacterial, thermal source and the effect of Organic substance power that can effectively go in eliminating water, and size is bigger than membrane aperture
Solute molecule is rejected by into concentrated solution.
When ultrafilter membrane when in use, because it is to antibacterial in water or solution, microorganism, colloid, suspended solid and solvable
Property macromolecular compound there is high rejection effect, be deposited on film surface formed pollution, make the through performance and rejection of film
Can deteriorate.In addition the attachment of antibacterial, microorganism, its metabolite forms mucus on film surface.These factors will all cause ultrafiltration
Film properties are reduced, so ultrafilter membrane carries out regularly backwash and can separate attachment dirt material on the surface of the film.Conventional
Ultrafilter membrane backwashing technology mainly has three kinds：The first be filtration after water purification with water pump pressurize reversely through ultrafilter membrane realize
Backwash, high cost, volume are big, are not suitable for domestic；Second is changed the direction of a stream of water using water valve, allows raw water back through super
Filter membrane realizes backwash, and cost of implementation is low, but can pollute clean water area；The third method is, using the ultrafiltration core of more than two, to lead to
Water valve switching water (flow) direction is crossed, with the water purification of a wherein filter element reversely through the filter membrane of other filter elements realizing backwash, into
This height, volume are big, are difficult to promote the use of.
The maximum traditional water purification machine of the current usage amount of China, filter cartridge construction standard configuration is：PP cottons+granular active carbon+pressure
Contracting activated carbon（Or PP cottons）+ reverse osmosis membrane+post active carbon, typically no ultrafiltration membrane filter element in Pyatyi filter element, on rural area ground
When the poor area of the water quality such as lower water uses, because colloidal content is high in raw water, biological pollution is serious, reverse osmosis membrane is because above
Three-level filter element can not preferably play filtration protective effect and easily lead to dirty stifled in the short time.And if simple in reverse osmosis
Add a ultrafilter membrane before permeable membrane, do not set up ultrafilter membrane flusher, the dirty stifled, pure water of ultrafilter membrane may be caused within a period of time
The situation that aquifer yield is reduced, in some instances it may even be possible to which blocking up because ultrafilter membrane is dirty makes the long-term hydropenia idle running of booster pump（Ultrafilter membrane booster pump it
Before）, the long-term running at full capacity of booster pump（Ultrafilter membrane is after booster pump）, ultimately result in booster pump decompression and damage and then cause anti-
Permeable membrane is run under conditions of pressure is inadequate, accelerates dirty stifled situation generation.
The content of the invention
The purpose of this utility model is the defect existed for above-mentioned prior art, there is provided a kind of improved pure water
The water purifier of backflow backwash ultrafilter membrane.
The utility model proposes pure water backflow backwash ultrafilter membrane water purifier include：Pass sequentially through entering for pipeline connection
Water threeway, PPF candle filters, active carbon filter core filter and ultrafiltration membrane filter element filter, booster pump, reverse osmosis membrane filtration
Device, high-voltage switch gear and Postposition carbon filter, described high-voltage switch gear outlet by a threeway simultaneously with post active carbon mistake
Filter and a Pressured water tank connect, and Postposition carbon filter outlet is connected with outlet, described reverse osmosis membrane filt
Outlet be provided with discharge of wastewater pipeline, the Pressured water tank is by a reflux line and a Unidirectional solenoid valve and ultrafiltration membrane filter element
Filter connects.
The bottom of described ultrafiltration membrane filter element filter is provided with scouring electromagnetic valve.
In the first embodiment, described electromagnetic valve adopts check valve, from the reflux line that the Pressured water tank is drawn
It is connected to the outlet of ultrafiltration membrane filter element filter.
In a second embodiment, described electromagnetic valve adopts check valve, from the reflux line that the Pressured water tank is drawn
It is connected to the outlet of booster pump.
In the third embodiment, described electromagnetic valve adopts check valve, and from described return flow solenoid valve check valve is adopted, from
The pure water pipeline that the Pressured water tank is drawn is by a threeway and the outlet of booster pump and going out for ultrafiltration membrane filter element filter
Mouth connection.
In the fourth embodiment, described electromagnetic valve adopts check valve, described return flow solenoid valve to adopt check valve, from institute
State the reflux line of Pressured water tank extraction by the entrance of four-way and booster pump, the outlet of ultrafiltration membrane filter element filter and
The entrance connection of reverse osmosis membrane filt.
Relative to common backwash ultrafiltration membrane technique, this utility model has a two big advantages, and first, use pure water rinsing ultrafiltration
Film is cleaner than what is rinsed with tap water and ultrafilter membrane purified water, and flushing finishes rear ultrafilter membrane and is immersed in pure water, can be further
Soften the fouling dirt on film surface, carry out once being more prone to the dirt on ultrafilter membrane along rinsing when the next one is with the water cycle
Remove, make ultrafilter membrane be in a cleaner environment, be less susceptible to stifled film.Second, the pure water of pressure pot has stable hydraulic pressure, then
When carrying out backwash, relative to the backwashing manner by tap water pressure（Note：Domestic many area hydraulic pressure are unstable）, this practicality is newly
The flushing strength of type is more powerful, more thoroughly.Ultrafilter membrane service life is longer.
