Abstract
The utility model relates to a two-stage reverse osmosis water purifier for a pre-ultra-filter, which comprises a first-stage high pressure pump, a first-stage reverse osmosis device, a two-stage high pressure pump and a two-stage reverse osmosis device which are connected orderly by a pipeline, wherein the front of the first grade high pressure pump is connected with an ultra-filter. The utility model the advantages that the dirt blocking coefficient of pretreated water which enters the reverse osmosis device can be kept below 3, and thus the service life of a reverse osmosis membrane can be prolonged and the running cost of equipment can be reduced; the overall structure of the two-stage reverse osmosis water purifier for a pre-ultra-filter is simple and compact and occupation area is small.
Description
Technical field
The utility model relates to the treatment unit of water, particularly utilizes the device of ultrafiltration and reverse osmosis membrane processing water.
Background technology
At present, the two-pass reverse osmosis water treatment device with outstanding advantages such as its environmental protection, full-automatic running, stable effluent quality, has obtained using widely in industries such as beverage, chemical industry, electric power, electronics.And, the treating water quality is further improved through the applicant's improved " two-pass reverse osmosis pure water device " (patent No. is 01252857.9), and more reliable and more stable, thus extend to the sector applications such as pharmacy higher to water quality requirement.But existing reverse osmosis unit still has weak point, and for example, its reverse osmosis membrane vulnerable to pollution is so to the having relatively high expectations of pre-treatment water quality, dirt-block modulus need be controlled at below 4.And existing former water pretreatment generally all adopts washed ore filtration, activated carbon filtration and secondary filter to filter, above-mentioned pretreatment unit is not only bulky, operation is complicated, the working cost height, and Yuan Shui contain pollutent more, when water quality is relatively poor, often be difficult to reach the specification of quality of pretreated water, thereby make reverse osmosis membrane contaminated and reduction of service life.
Summary of the invention
The technical problem that the utility model quasi-solution is determined is: provide that a kind of its pretreatment unit is simple in structure, the little occupation of land of volume less, strong to raw water quality fluctuation adaptability, the drainage steady quality is reliable, and the high two-pass reverse osmosis pure water device of water use efficiency.
The technical solution of the utility model is: it comprises one-level high-pressure pump, first-stage reverse osmosis device, secondary high-pressure pump, the two-pass reverse osmosis device that is linked in sequence with pipeline, and is connected with ultra-fine filter before the one-level high-pressure pump.
The beneficial effects of the utility model are: it can make the dirt-block modulus SDI value of the pretreated water that enters counter-osmosis device remain on below 3, thereby prolong the work-ing life of reverse osmosis membrane greatly, reduction equipment working cost, and this equipments overall structure is simply compact, floor space is few, and water use efficiency increases.
Description of drawings
Accompanying drawing is the utility model overall structure synoptic diagram.
Embodiment
The utility model is described in further detail with embodiment below in conjunction with accompanying drawing.
The present embodiment device mainly is made up of ultra-fine filter 3, one-level high-pressure pump 7, first-stage reverse osmosis device 9, secondary high-pressure pump 13, two-pass reverse osmosis device 15 and each connecting tube.Because ultra-fine filter 3 needs back flushing continually, in order to keep quantity-produced stability, is provided with ultrafiltration pretreatment water storage tank 5 between ultra-fine filter 3 and one-level high-pressure pump 7, is provided with intermediate water tank 11 between first-stage reverse osmosis device 9 and secondary high-pressure pump 13.Its Production Flow Chart is, initial filter water 1 is sent into ultra-fine filter 3 through pipeline 2, pretreated water behind ultrafiltration membrance filter enters ultrafiltration pretreatment water storage tank 5 by pipeline 4, storage tank 5 outlets are joined with pipeline 6 and one-level high-pressure pump 7, the outlet of one-level high-pressure pump is sent to first-stage reverse osmosis device 9 by connecting tube 8 with pretreated water, the first-stage reverse osmosis device produces water and enters intermediate water tank 11 through pipeline 10, the import of secondary high-pressure pump 13 is connected with intermediate water tank outlet pipe 12, outlet connects the import of two-pass reverse osmosis device 15 through pipeline 14, and the output water after the two-pass reverse osmosis device is handled is sent to the finished product water storage tank by pipeline 16.The dense water part of two-pass reverse osmosis device 15 is connected to through concentrate recirculation pipeline 17 on the water inlet pipe 12 of secondary high-pressure pump, and a part is connected to ultrafiltration pretreatment water storage tank 5 by return line 18.All be provided with control valve 19 on above-mentioned each connecting tube.
Claims (3)
