Embodiment
The present invention program is further elaborated with reference to embodiment.
A kind of disc tube reverse osmosis (dt-ro) film integrated film separator of preposition pretreatment and the structure of flow guiding disc of the present invention
It is：
The disc tube reverse osmosis (dt-ro) film integrated film separator and flow guiding disc of a kind of preposition pretreatment, mainly including pressure vessel,
Flange, center pull rod, flow guiding disc, disc tube reverse osmosis (dt-ro) film bag, preposition pretreatment gradual change filtering material, connecting line and sealing
Circle.Upper portion is the by-pass filtration stage, and the lower section is the secondary filtration stage.Upper flanges 2, multiple flow guiding discs 5 and lower end
Flange 15 stacks successively, and is fixed on center pull rod 1 within pressure vessel, the upper portion of device each two flow guiding disc it
Between load preposition pretreatment filtration material 4, the lower section loads disc tube reverse osmosis (dt-ro) film bag 6 between each two flow guiding disc, close
Seal is located in the groove of flow guiding disc two sides, for separating permeate and concentrate, preposition pretreatment gradual change filtering material and dish pipe
It is not in contact with each other between formula reverse osmosis membrane bag and upper and lower flow guiding disc, forms liquid flow path.The each two water conservancy diversion of the lower section
The distance between disk is equal, and upper portion is gradually reduced along the distance between water (flow) direction each two flow guiding disc, and to the last two
The distance of a flow guiding disc and the distance of the lower section each two flow guiding disc are equal.
Disc tube reverse osmosis (dt-ro) film integrated film separator and the flow guiding disc work of a kind of preposition pretreatment of the present invention are former
Reason and the course of work are：
For raw water out of upper flanges water inlet 3 inflow device, the passage between flow guiding disc and pressure vessel flows to upper portion
Bottom, and flow quickly through it is preposition pretreatment gradual change filtering material, then 180 degree reverse to it is preposition pretreatment gradual change filtering material
Another side, then next flow guiding disc is flowed into from flow guiding disc, so that in the surface shape of preposition pretreatment gradual change filtering material
Into by flow guiding disc circumference to circle center, then to circumference, then the route to circle center, condensed water is from 10 row of upper flanges water outlet
Go out, by-pass filtration complete, by-pass filtration water from center pull rod upper end water outlet 9 by pipeline 11 flow into the secondary filtration stage, one
Level crosses water inlet 15 inflow device of the drainage from lower end flanges 16, and the passage between flow guiding disc and pressure vessel flows to hypomere portion
The top divided, and disc tube reverse osmosis (dt-ro) film bag is flowed quickly through, then 180 degree reverses the another side to film bag, then from flow guiding disc
Next flow guiding disc is flowed into, the salient point when system running pressure becomes larger or water flow increases on flow guiding disc becomes larger, when being
Salient point when system operating pressure diminishes or water flow reduces on flow guiding disc diminishes, and the salient point on flow guiding disc is to system pressure size
Change in real time with water flow size, so that formed in film surface by flow guiding disc circumference to circle center, then to circumference, then arrive
The route at circle center, condensed water are discharged from the water outlet 7 of lower end flanges, water outlet of the secondary filtration pure water from hypomere center pull rod 13
Mouth 8 is discharged, into pure water collection device.
