Abstract
The invention discloses a waterway technology with water production fresh-keeping and filter core system self-cleaning maintenance and a control system. A self-cleaning maintenance mechanism comprises a water inlet pipe system connected with an outlet of a tap water pipe, a drainage pipe system connected with an outlet of the water inlet pipe system, and a control system equipped with an electric controllable valve arranged in the drainage pipe system and a monitoring device arranged in the water inlet pipe system or the drainage pipe system. The control system determines on and off of the electric controllable valve according to comparison of a signal of the water inlet pipe system in a standby state obtained by information monitored by the monitoring device and a preset standby state time threshold, and controls water flow in the water inlet pipe system cyclically and discharges accumulated water in a pipe an a filter core. The problems are solved that when a present purifier is located in a non-operating state for a long time, microbes breed and gather in the filter core and membrane elements, filter core performances are affected, pollution of a reverse osmosis membrane is aggravated, dissolved oxygen of standing water in purifier without water flow is reduced and water quality changes along with time prolongation, and thus the accumulated water has a poor freshness degree and is not suitable for direct drinking.
Description
Technical field
The invention belongs to water treatment field, be specifically related to one and have that water processed is fresh-keeping, water route technique and control system are safeguarded in cartridge systems self-cleaning.
Background technology
Water is Source of life, the quality of Drinking Water matter and the healthy closely related of people.Show according to the World Health Organization (WHO) (WHO) investigation, in developing country, the disease of 80% is caused by unsafe water and severe sanitary condition, and wherein women and children are the most serious by harm.Because industrial sewage and sanitary wastewater constantly enter arbitrarily in river, open water supply water pollution is caused constantly to be aggravated, " old three sections " of adopt traditional water technology and coagulant precipitation, filter, disinfecting carry out that the tap water of purified treatment is more and more difficult obtains good water quality, are even difficult to the hygienic standard reaching potable water.At present, the population of state-owned 1/4th is drinking the water not meeting hygienic standard, and " water pollutions " has become the main environmental problem of China.Along with improving constantly of the fast development of economy and people's income and living standard, comprise the requirement of drinking water quality also more and more higher to quality of life, drinking water safety becomes with healthy the focus and focus that receive much attention gradually.
In recent years, in order to improve water quality and the security of potable water, increasing purifier entered huge numbers of families, became the daily necessities of herbal gradually.At present, the purifier on market all uses changeable type filter core mostly.Because though the filter effect of purifier is excellent, after but the filter core in purifier uses a period of time, cartridge surface can amass the sediment in attached a large amount of tap water, as cleaned not in time, sediment will affect the filtering efficiency of filter core, and the time is slightly long, meeting breed bacteria in sediment, pollute water purifier, affect water purification, even hidden danger is brought to the security of water, therefore water purifier must be dismantled by water purifier at set intervals, take out filter core to carry out cleaning or changing, in filter element cleaning process, need to adopt various chemical, not only increase use cost, and the remaining clean-out system do not cleaned up can accumulate in filter core, need to clean use for a long time, just can residual quantity be made gradually to reduce, Long-Time Service is not only bad for the health of drinking person, remaining clean-out system is cleaned up, virtually waste a large amount of water resources, trivial operations, and make troubles and potential safety hazard to user, if and have accidentally in filter core installation process, very easily damage filter core, reduce the serviceable life of filter core, if more renew cartridge, then substantially increase the cost of purifying waste water, and the filter core mating this purifier need be selected, if have selected unmatched filter core, water purifying effect is influenced, adverse effect may be caused to purifier built-in system, reduce the life-span of purifier.
For this reason, market there is the purifier with self-cleaning function, without the need to chemical cleaning or more renew cartridge, not only reduce use cost, avoid the use of inconvenience that stripping assembly brings and chemical, flow dynamic can be utilized to clean up the dirt of element kit outside surface and endoporus and impurity in purifier internal system.From rinsing disclosed in water purifier solenoid directional control valve from rinsing water purifier disclosed in Chinese patent literature CN104358894A, multi-usage high-pressure pump is adopted to carry out forward flushing and counterflush to RO membrane cartridge and PPF filter core respectively, from pressure of return water tank, the use water automatically cleaned is sucked by the high-pressure pump suction hose connected with solenoid directional control valve transverse port, when multi-usage high-pressure pump implements forward cleaning to RO membrane cartridge, multi-usage high-pressure pump is just rinsing the High-Pressure Water of generation, inject from the water inlet port of RO membrane cartridge, via RO membrane cartridge, RO yield regulates mouth, the transverse port of solenoid directional control valve E42, from flushing shunt valve, from flushing by-pass tee, retaining valve, return main, finally import in pressure of return water tank, when multi-usage high-pressure pump implements reverse cleaning to PPF filter core, the High-Pressure Water that the back flush of multi-usage high-pressure pump produces, via the transverse port of solenoid directional control valve D37, high pressure backflushing pipe, to port on solenoid directional control valve A2, PPF filter core, the transverse port of solenoid directional control valve B7, directly enter in sewer finally by draining skirt.Achieve in such scheme purifier internal system filter membrane component from rinsing, easy to use, cost is low, extends the serviceable life of filter membrane component, solve filter membrane cleaning inconvenience in prior art, the problem that need regularly clean or replace.But also there is many deficiencies in such scheme, specific as follows: the filter membrane component 1, in system all can not carry out auto-flushing, only PPF filter membrane and RO reverse osmosis membrane can carry out auto-flushing, other filter membrane UDF, CTO also need to change or cleaning in use for some time, therefore the function achieved from rinsing of this system only part; 2, water used is rinsed in system from the water in pressure of return water tank, this water is rinse the water in the sewage remittance pressure of return water tank of RO reverse osmosis membrane, and rinsing water used is not clean water, and the developing result so for filter membrane is limited, even more block filter membrane, damage filter membrane; 3, when this water purifier is in standby off position, because water purifier is in off position for a long time, purifying waste water of accumulating in whole pipe system and each filter core is in first valve state, easy formation microorganism grows and enrichment in filter core and membrane component, thus affects the pollution of filter core performance and aggravation reverse osmosis membrane; 4, the potable water moment in guarantee system after purification " freshness " cannot be kept, when water purifier system does not use for a long time, accumulate in purifying waste water in system pipeline can not regularly discharge, easy breed bacteria and microorganism, affect water quality and the freshness of potable water, even bring safe drinking water hidden danger.
Summary of the invention
