Technical field
The utility model relates to the structure improved technologies of EDI high purity water treatment device, and more specifically, it relates to one kind
EDI constant pressure and flow protective device.
Background technique
EDI, that is, continuous electrodeionization abbreviation, for it is reachable to produce water resistance rate by the further deep processing of reverse osmosis produced water
To the ultrapure water rank of 16.0M Ω .cm.EDI must apply DC power supply at work, to guarantee the continuous of internal potting resin
Exchange.It is otherwise internal to heat up quickly but also just because of this characteristic, flow cannot be too small when being powered on by EDI, it may burn
Bad membrane stack.
Since ultrapure water cannot be stored, it is necessary to produce and use, so the production water of EDI is all direct-furnish, but due to the use of user
Water may be variation, so the water amount of EDI is just also to follow variation, when flow is too small or does not have to water, just there is burning
Bad danger.Common practice is in EDI concentrated water side installation traffic protection switch (FS in such as attached drawing 3), setting in the industry at present
One protection value stops powered by direct current when flow is lower than setting value.Pure water side is then to pass through hand by the way of reflux
Dynamic regulating valve F7 flows back EDI production water.But the problem of doing so is: when water consumption is big, because some water flows back
, will lead to insufficient water；When water consumption is small, EDI flow may be suppressed too small again.So the aperture of return valve F7 will frequency
It is numerous to go to adjust, or fixed aperture, but to endure the risk for influencing to produce or EDI is impaired.
Summary of the invention
