Description
Technical field
The utility model relates to the high-purity wetting systems of the field of medical instrument technology more particularly to a kind of clinical laboratory.
Background technique
Currently, pure water, high purity water, ultrapure water are that modern industry is indispensable and one of highly important basic material,
The fields such as electronics, electric power, chemistry, medicine, biology, information have very extensive purposes；It is especially all kinds of for medical institutions
Clinical laboratory, due to it is larger to pure water demand and also to water quality requirement it is higher, it is accordingly required in particular to one kind can utilize tap water or phase
Nearly water source facilitates the integral intelligent equipment for preparing high purity water as raw water.
In high purity water producing process, mixed bed (ion exchange bed) or EDI (electrochemical deionization) equipment is generally used, it will be former
Water carries out deionization purification, makes the resistivity of water up to 15m Ω .cm or more.And after mixed bed or EDI electrification deionization apparatus, it needs
When buffer tank is set, the storage problem of high purity water must be just paid the utmost attention to.Because high purity water after contacting with the air will
It is heavily polluted, containing impurity such as carbon dioxide, bacterium, dust in air, and high purity water is pure solvent, to these impurity
Solvability is very strong, once its resistivity will be made to decline rapidly, in practice it has proved that 15m Ω .cm so high purity water is contacted with air
Above high purity water, water quality will drop to 3-4m Ω .cm after 1 minute in air for exposure, will drop to 2m after 3 minutes
Ω .cm or so.Therefore it has to reduce the chance that high purity water is contacted with air.High purity water is unable to reach user if contaminated
Requirement causes back segment system to purify burden, leads to the increase of operating cost.
In the prior art, prevent high purity water from having following 3 kinds by the common methods of air pollution:
(1) nitrogen charging method: nitrogen is filled on the water tank water surface to be made to maintain normal pressure appropriate in water tank, prevents atmosphere and water
The water surface contacts in case, and air-isolation prevents pollution effects up to 95% or more；
(2) bag film method: being arranged bag-shaped film i.e. in water tank and be covered on the water surface, and bag film following water-level lifting is reduced
The water surface and air contact area, due to the sealing problem of bag film and four wall of water tank, so air-isolation prevents pollution effects only
Have 50% or so；
(3) floating roof method: monolith plate floating roof is made in water tank with the light light material of density ratio water and is bubbled through the water column, is used in combination
Light elastic material (such as sponge, foamed plastic) covers the gap between floating roof and water tank, and floating roof is with water surface fluctuation, to reduce
The touch opportunity of air and the water surface；Also due to the sealing problem of floating roof method material and four wall of water tank, air-isolation prevent from polluting
Effect only has 50% or so.
It is most common that high purity water is stored in a manner of nitrogen envelope in the prior art, implements most simple, and effect is best.And it uses at some
In the industry of high purity water, many users can not provide nitrogen, therefore be difficult to guarantee the quality of high purity water, cause back segment system negative
Load increases, and the serious company that will directly influence normally produces.
Chinese patent (Publication No. CN202108075U) discloses water seal device for high purity water storage
The connected high-purity water tank of pure water equipment, is additionally provided with prime water tank before mixed bed or EDI pure water equipment, and high-purity water tank top is original
Gas vent is connected by return pipe with prime tank top water inlet, and prime water tank bottom water outlet is set with mixed bed or EDI pure water
Standby water inlet is connected.High-purity water tank fills after high purity water extra pure water and is back to prime water tank from the return pipe of tank top, together
When high purity water water tank form a closed space completely and air insulated, after high purity water roof tank water quality reaches requirement, water
Case water can be supplied or be used backward, according to live actual used water amount, in water seal return pipe always can some water flowing back,
Water seal is formed, prevents high-purity water pollution, effect can be suitable with nitrogen charging method.But the high purity water storage water seal dress that the patent provides
Set the gas for not accounting for and dissolving in raw water, in raw water dissolved with gas by constantly accumulating, generate a large amount of gas not
It will result only in high purity water secondary pollution, can also destroy the internal pressure of water seal increase high-purity water tank in return pipe by being temporarily stored in,
The high purity water for the water seal device for high purity water storage production that the patent provides can not obtain the pure water of high-quality.
