Description
Technical field
The present invention relates to a kind of equipment that utilizes reverse osmosis concentrated water as hyperfiltration rinsing water, belong to pure water preparation apparatus technical field.
Background technology
Along with the extensive application of membrane technique, ultrafiltration+ro treatment technology becomes the main flow technology that pure water is produced system.There is following problem in this technology at present:
1, the ultra-filtration membrane flushing cycle is short, washes once about 1 minute of each washing length in general 0.5～1 hour.Current at present way is to establish the hyperfiltration rinsing water pump.The numerous start and stop of pumping frequency like this.Every 0.5～1 hour, the ultrafiltration flushing pump will start and stop once, only move 1～2 minute at every turn, the utilization ratio of pump is not high, and frequent start-stop also makes pump fragile.
2, the general and ro treatment technology of ultrafiltration is united use, and the pressure of reverse osmosis concentrated water is higher, reaches about 1.5MPa.Utilize present existing method to reclaim this part energy, economic benefit is not remarkable.In the at present domestic engineering, this part energy has generally all wasted.
Summary of the invention
At the deficiencies in the prior art, the invention provides a kind of reasonable in design, simple in structure, easy to use, economize on resources, less investment, adaptability is good, the equipment that utilizes reverse osmosis concentrated water as hyperfiltration rinsing water that can generally promote.
The present invention realizes by following scheme:
A kind of equipment that utilizes reverse osmosis concentrated water as hyperfiltration rinsing water comprises high-volume pressure reduction vessel, piston and valve; Piston is installed in high-volume in the pressure reduction vessel, reverse osmosis concentrated water pipe is connected with the water-in of pressure reduction vessel high-volume by pipeline and pressure reduction vessel inlet valve high-volume, and high-volume the water outlet of pressure reduction vessel is by pipeline and high-volume pressure reduction vessel flowing water Valve and hyperfiltration rinsing water pipe coupling; Between the water outlet of reverse osmosis concentrated water pipe and pressure reduction vessel high-volume by pipeline and high-volume pressure reduction vessel against the current valve be connected, high-volume be connected by pipeline and water discharging valve between the water-in of pressure reduction vessel and the pond.
Described high-volume pressure reduction vessel is two cylinders that fuse, and the diameter of an end cylinder that connects reverse osmosis concentrated water pipe is less than the diameter that connects hyperfiltration rinsing water Guan Yiduan cylinder.
Described piston is made up of the two portions that fuse, and its external diameter internal diameter of cylinder residing with it respectively adapts.
The method of work of aforesaid device is as follows:
When 1) ultra-filtration membrane being washed, open high-volume pressure reduction vessel inlet valve and high-volume pressure reduction vessel flowing water Valve, close high-volume pressure reduction vessel valve and water discharging valve against the current, the pressure that utilizes reverse osmosis concentrated water water filling in pressure reduction vessel high-volume, high-volume the water of pressure reduction vessel right-hand member is discharged simultaneously, is used for ultra-filtration membrane is washed; Because the area difference at two ends, the piston left and right sides, high-volume the flooding velocity of pressure reduction vessel left end is less than the water flow of pressure reduction vessel right-hand member high-volume, high-volume the intake pressure of pressure reduction vessel is greater than the discharge pressure of pressure reduction vessel high-volume, thereby reaches the water yield and the pressure requirement of ultra-filtration membrane wash water;
2) after the ultra-filtration membrane flushing finishes, close high-volume pressure reduction vessel inlet valve and high-volume pressure reduction vessel flowing water Valve, open high-volume pressure reduction vessel valve and water discharging valve against the current, reverse osmosis concentrated water is from the water filling to pressure reduction vessel high-volume of the water outlet of pressure reduction vessel high-volume, utilize reverse osmosis concentrated water pressure high-volume the water in the pressure reduction vessel enter the pond, for back flushing is next time prepared.
Among the present invention,, be used as the wash-down water of ultra-filtration equipment, solved the drawback of prior art because reverse osmosis concentrated water water quality is better, have reasonable in design, simple in structure, easy to use, economize on resources, less investment, adaptability is good, the advantage that can generally promote.
