Description
Technical field
The present invention relates to a kind of equipment and method of work thereof of amplifying reverse osmosis concentrated water as hyperfiltration rinsing water, belong to pure water producing equipment technical field.
Background technology
Along with the extensive application of membrane technology, 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 milipore filter 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 rate 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.
Because reverse osmosis concentrated water water quality is better, can be used as the flushing water of ultrafiltration apparatus.The water yield by amplifying reverse osmosis concentrated water can solve above-mentioned two problems simultaneously as the flushing water of ultrafiltration apparatus.
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, small investment, adaptability is good, the equipment of the amplifying reverse osmosis concentrated water as hyperfiltration rinsing water that can generally promote.
The present invention realizes by following scheme:
A kind of equipment of amplifying reverse osmosis concentrated water as hyperfiltration rinsing water comprises reverse osmosis concentrated water tank, injection apparatus and decompressor; Reverse osmosis concentrated water tank is connected with reverse osmosis concentrated water pipe by dense tank intake valve of water, is connected with drainpipe with injection apparatus with dense water tank drain valve by the injector suction valve respectively simultaneously; Injection apparatus is connected with reverse osmosis concentrated water tank with reverse osmosis concentrated water pipe with the injector suction valve by the injector water intaking valve respectively, is connected with decompressor simultaneously; Decompressor is a pressure-reducing valve.
Described injection apparatus is composed in series by a plurality of injectors.
The method of work of the said equipment is as follows:
When milipore filter washes, close injector water intaking valve and injector suction valve, open dense tank intake valve of water and dense water tank drain valve, make reverse osmosis concentrated water pipe to reverse osmosis concentrated water tank water filling, when water filling was excessive, superfluous water was by dense water tank drain valve discharging; When milipore filter is washed, close dense tank intake valve of water and dense water tank drain valve, open injector water intaking valve and injector suction valve, injection apparatus and the pressure-reducing valve formed by the multi-stage jet device from the High-Pressure Water of reverse osmosis concentrated water pipe wash milipore filter; When High-Pressure Water is flowed through injection apparatus, in injector, produce negative pressure, thus will be anti-
The water yield by the quantity regulating of adjusting injector in the injection apparatus is washed milipore filter when the water yield that needs is big, increases injector quantity; The water yield that needs hour reduces injector quantity.
Regulate the pressure of the water that milipore filter is washed by adjusting pressure-reducing valve.
The present invention is reasonable in design, simple in structure, easy to use, economize on resources, small investment, and adaptability is good, has promotion prospect preferably.
