A kind of anti-clogging detection device of reverse osmosis (RO) film
Technical field
The utility model relates to reverse osmosis (RO) technical field of membrane, and in particular to a kind of anti-clogging detection dress of reverse osmosis (RO) film It sets.
Background technique
Infiltration is a kind of physical phenomenon.Contain the water of different salts when two kinds, is such as separated with a semi-permeable film It finds that the moisture on one side of low salinity can be seeped into the high water of salt content through film, gradually the salt concentration on both sides Until being fused to equalization, this process is known as permeating.Take a long time however, to complete this process.But if in saliferous High water side is measured, a big pressure is applied, direction can be made to permeate to opposite direction, and salinity is remaining, this process is known as reverse osmosis Thoroughly.Osmosis filtration principle imposes the pressure bigger than naturally osmotic pressure, makes exactly in the water for having impurity (such as raw water) Infiltration carries out round about, the hydrone pressure in raw water to the another side of film, becomes clean water, to reach removing The purpose of impurities in water, salinity.
RO film is in use, be easy to be attached in RO film surface and hole because of a large amount of depositions of substance in water, cause RO film Blocking leads to that water yield becomes smaller and filtering water is not clean.And this deposited phenomenon occurs mainly under water stationary state, stream Dynamic water flow is not allowed to be also easy to produce depositional phenomenon.RO system at work, because water is in flowing, is actually not easy precipitating knot Dirt and stifled film problem occurs.And when RO system is in standby, high concentration water in RO film, because of long-time quiescent setting, water Middle substance (such as calcium ions and magnesium ions) can largely deposit the phenomenon that being attached to RO film surface, resulting in blockage (film is blocked up in fouling), lead to after deposition Crossing water flow flushing can not reach and rinse out deposition completely, affect the practical effect of RO system.
Currently, it is built-in with the water-strainer or water purifier of reverse osmosis (RO) film, one-side detection water quality, if water quality detection When unqualified, alarm etc. occurs;Where the problem of can not detecting RO film well, user is only capable of carrying out by disassembly RO film It checks, remakes replacement or flushing, bring great inconvenience to users.
