Description

Water purifier

Technical field

The utility model is related to discharge of wastewater water cleaning systems, more specifically, it relates to a kind of water purifier.

Background technology

China most cities using III class surface water, rural area mainly using IV class underground water as drinking water source, with dirt The problems such as aggravation of dye, two worms (giardia lamblia stiles, Cryptosporidium), blue-green alge, heavy metals exceeding standard, seriously threaten town and country and drink Water security.Therefore, surface water, underground water have to pass through purification and could used as drinking water.Present family expenses, commercial potable water Reason technological core is mainly membrane filtration technique.One of which is ultrafiltration membrance filter, and pore size filter is 0.01 micron, can be removed complete The muddy thing (such as silt, iron rust) in portion, pathogenic microorganisms (such as parasite, bacterium, virus) can also be removed most big Molecular organic, while be not required to electricity consumption, does not produce waste water, is relatively adapted to the preferable city of southern china water-quality ratio, but because can not A variety of harmful or heavy metal ion such as carcinogen and lead, mercury such as organic compound, radioactive radon, the arsenic gone in water removal, The poor northern area of water quality and vast rural area, can not just meet the drinking water treatment demand of safety and Health.It is another It is reverse osmosis membrane filtration, filtration openings footpath is 0.0001 micron, all harmful substances that can be gone completely in water removal only retain water Molecule output pure water, applicability is wide, is the main force of water process in Chinese vast both urban and rural area.But with the water purification machine of reverse osmosis membrane Because the operation principle of reverse osmosis membrane, need to discharge substantial amounts of waste water (condensed water) during pure water is produced, by water temperature, water quality Influence, output portion pure water need to discharge 3-5 parts of waste water.The present situation of this surprising waste water of output is the section advocated with the country Learn development and require mutually to deviate from " energy-conservation, the consumption reduction " built a conservation-minded society.

It is micro- useless that a kind of flash is disclosed in Publication No. CN203781935U patent document (referred to hereinafter as documents 1) Water discharges water cleaning systems, including：Pass sequentially through pipeline connection inlet triplet for water, fore filter group, booster pump, reverse osmosis membrane mistake Filter and Postposition carbon filter, the Postposition carbon filter outlet are connected by high-voltage switch gear with delivery port, reverse osmosis The outlet of permeable membrane is connected by pipeline with a Pressured water tank simultaneously, it is characterised in that the reverse osmosis membrane filt Outlet is provided with discharge of wastewater pipeline, and the pipeline is provided with an impulse electromagnetic valve；The Pressured water tank is by a pipeline and unidirectionally Valve flows back micro pure water to the front end of reverse osmosis membrane filt.

Although the micro- discharge of wastewater water cleaning systems of flash disclosed in documents 1 can effectively improve the profit of raw water With rate, in the case where ensureing water quality safety, moreover it is possible to accomplish energy-saving and emission-reduction；But, the water quality in each area differs, net installing , it is necessary to manually detect the TDS values of raw water during water dispenser, then, above-mentioned impulse electromagnetic valve is set further according to the TDS values of measure Opening and closing time, still, most user only can just detect the TDS values of raw water when using water purifier when installing water purifier, Detected without the regular TDS values to raw water, even, some have user when installing water purifier, also do not detect The TDS values of raw water, this may result in the opening and closing time of impulse electromagnetic valve and is not adapted to the TDS values of raw water, and this just most probably leads Cause reverse osmosis membrane to block, or even cause the use time of reduction reverse osmosis membrane.
