Abstract
An electric desalting device adopting a reverse-osmosis direct-connecting technology comprises a water inlet pipeline.The water inlet pipeline is connected with a reverse-osmosis component through a booster water pump and a water inlet control valve, the reverse-osmosis component is in output connection with an electric desalting module, the output end of the electric desalting module is provided with a water outlet pipeline, and a decompression solenoid valve is arranged between the output end of the reverse-osmosis component and the input end of the electric desalting module.After the device is shut down, the solenoid valve is switched on, pressure on the fresh water side of the reverse-osmosis module is released, and reverse-osmosis membrane damage caused due to the fact that after the booster water pump stop working, a reverse pressure difference of a reverse-osmosis membrane is too large is prevented.Due to the fact that the reverse-osmosis and electric desalting direct-connecting technology is adopted, a middle transition water tank is omitted, the size of the electric desalting device is greatly decreased, and the use requirements of ships, naval vessels and the like which are limited in space can be met.
Description
Technical field
The present invention relates to a kind of electric demineralizer adopting reverse osmosis direct-connecting technology.
Background technology
Electricity desalination technology (EDI) is a kind of electrodialysis and the ingenious technique combined of Features of Ion Exchange Process.The internal structure of electricity desalination module and electrodialyzer basic simlarity, the two is distinctive in that electricity desalination module is filled with anion-cation exchange resin in freshwater room, this technique has concentrated ion exchange and electrodialytic advantage, overcomes again the polarization phenomena in electrodialytic process and ion exchanges the drawback needing chemical regeneration.Electricity desalination technology has become manufacture high purity water prefered method.
Owing to the amount of resin in electricity desalination module is less, necessary life-time service again, for avoiding resin by water rapid failure, the total salinity in water inlet is had strict restriction by electricity desalination module.Therefore, the water inlet of electricity desalination module need to be done pretreatment, the preposition desalination preprocess method of electric desalination that reverse osmosis is conventional.Generally, after reverse osmosis produced water is introduced water tank, then deliver to from water tank electricity desalination module carry out deep desalting.Water tank be introduced for avoiding device shut down after, dilute side is forced through greatly, causes the damage of reverse osmosis membrane.Owing to adding middle transition water tank so that electricity demineralizer volume cannot meet more greatly the use needs of the limited space such as steamer, naval vessels.
Summary of the invention
Its purpose of the present invention is that a kind of electric demineralizer adopting reverse osmosis direct-connecting technology of offer; shut down rear electromagnetic valve when device and open release reverse osmosis module dilute side pressure; after preventing from quitting work because of booster pump, reverse osmosis membrane reverse differential pressure is excessive, and reverse osmosis membrane is caused damage.Owing to adopting reverse osmosis and electricity desalination direct-connecting technology, eliminate middle transition water tank, substantially reduce the volume of electricity demineralizer, the use needs of the limited space such as steamer, naval vessels can be met.
The technical scheme realizing above-mentioned purpose and take, including inlet channel, the intensified water pump of described inlet channel, water inlet control valve connect reverse osmosis module, reverse osmosis module output connects electricity desalination module, described electricity desalination module outfan is provided with outlet conduit, is provided with pressure release electromagnetic valve between described reverse osmosis module outfan and electricity desalination module input.
Beneficial effect
Compared with prior art the present invention has the following advantages.
The present invention adopts pressure release electromagnetic valve to control reverse osmosis freshwater lateral pressure, it is achieved that reverse osmosis is direct-connected with electricity desalination, eliminates intermediate water tank, reduces the volume of electricity demineralizer, enhance the space adaptability of device.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is this apparatus structure schematic diagram.
Detailed description of the invention
This device includes inlet channel 1, as shown in Figure 1, the intensified water pump 2 of described inlet channel 1, water inlet control valve 3 connect reverse osmosis module 4, reverse osmosis module 4 output connects electricity desalination module 6, described electricity desalination module 6 outfan is provided with outlet conduit 7, is provided with pressure release electromagnetic valve 5 between described reverse osmosis module 4 outfan and electricity desalination module 6 input.
Embodiment
This device includes inlet channel 1, booster water pump 2, water inlet control valve 3, reverse osmosis module 4, pressure release electromagnetic valve 5, electricity desalination module 6 and outlet conduit 7, as shown in Figure 1, described booster pump 2 provides pressure for reverse osmosis work, and the fresh water of reverse osmosis module 4 is delivered to electricity desalination module 6；Certain back pressure is there is in described electricity desalination module 6 in running, when electricity demineralizer quits work or during power-off, booster water pump 2 quits work, the dense water lateral pressure of reverse osmosis module 4 declines rapidly, pressure release electromagnetic valve 5 dead electricity is opened, release reverse osmosis module 4 dilute side pressure, it is prevented that reverse osmosis module 4 is caused damage because reverse differential pressure is excessive.
Claims (1)
1. the electric demineralizer adopting reverse osmosis direct-connecting technology, including inlet channel (1), it is characterized in that, described inlet channel (1) intensified water pump (2), water inlet control valve (3) connect reverse osmosis module (4), reverse osmosis module (4) output connects electricity desalination module (6), described electricity desalination module (6) outfan is provided with outlet conduit (7), is provided with pressure release electromagnetic valve (5) between described reverse osmosis module (4) outfan and electricity desalination module (6) input.
