Description
Technical Field
The utility model relates to a technical field of water treatment, specific novel sea water desalination coupled system that says so relates to and its systematic connection structure very much.
Background
With the rapid development of economy in China, the importance of seawater desalination is gradually reflected. Since the 60 s of the 20 th century, reverse osmosis desalination has become an important way for obtaining drinking water, and is an effective method for solving the shortage of fresh water resources. More than 99% of salt ions in the seawater can be removed through the reverse osmosis membrane, and drinkable fresh water is obtained.
The traditional seawater desalination system occupies a large area and is matched with equipment, so that the operation and maintenance are complex, and the early equipment investment is large. At present, a common seawater desalination system comprises an ultrafiltration water feed pump, an ultrafiltration device, a reverse osmosis high-pressure pump and a reverse osmosis device, and is also provided with a reverse osmosis low-pressure water feed pump and a cartridge filter, so that the operation and maintenance are complex. By analyzing the functions of the equipment and utilizing the mode of directly coupling the ultrafiltration device and the reverse osmosis high-pressure pump, a reverse osmosis low-pressure water supply pump and a security filter are omitted, and the system is simple and convenient to maintain.
Disclosure of Invention
An object of the utility model is to provide a novel sea water desalination coupled system to improve sea water desalination's stability, reduce area, reduce the input cost. Overcomes the defects in the prior art.
In order to realize the purpose, the technical scheme of the utility model is that: the utility model provides a novel sea water desalination coupled system, includes sea water pipeline and a plurality of ultrafiltration device, sea water pipeline is connected with ultrafiltration device's the end of intaking, is provided with the ultrafiltration feed pump on the pipeline between sea water pipeline and the ultrafiltration device, and ultrafiltration device's play water end is connected through pipeline and reverse osmosis unit's the end of intaking, is provided with the reverse osmosis high-pressure pump on the pipeline between ultrafiltration device and the reverse osmosis unit, and reverse osmosis unit's play water end and fresh water pipeline are connected, ultrafiltration device and reverse osmosis high-pressure pump direct coupling.
The utility model discloses a novel sea water desalination coupled system, through ultrafiltration system and reverse osmosis system direct coupling, saved low pressure feed pump and safety filter among the reverse osmosis system, reduce equipment investment cost in earlier stage, increase sea water desalination's stability.

Detailed Description
The invention will be further described with reference to the accompanying drawings.
The utility model discloses a novel sea water desalination coupled system, it is different from prior art and lies in: including sea water pipeline 1 and a plurality of ultrafiltration device 2, sea water pipeline 1 is connected with ultrafiltration device 2's the end of intaking, is provided with ultrafiltration feed water pump 3 on the pipeline between sea water pipeline 1 and the ultrafiltration device 2, and ultrafiltration device 2's play water end is connected with reverse osmosis unit 4's the end of intaking through the pipeline, is provided with reverse osmosis high-pressure pump 5 on the pipeline between ultrafiltration device 2 and the reverse osmosis unit 4, and reverse osmosis unit 4's play water end is connected with fresh water pipeline 6, and ultrafiltration device 2 and reverse osmosis high-pressure pump 5 direct coupling.
When the system is specifically implemented, a plurality of groups of ultrafiltration devices 2 are arranged in the system, the ultrafiltration devices 2 are connected in parallel, and an on-off valve is arranged in front of the water inlet end of each ultrafiltration device 2 and used for independently controlling the working state of each ultrafiltration device 2, so that the daily maintenance is convenient, and the maintenance is realized without stopping. A plurality of ultrafiltration cores are arranged in the ultrafiltration devices 2, a secondary ultrafiltration feed pump 7 is further arranged on a pipeline between the adjacent ultrafiltration devices 2, the number of the ultrafiltration cores in the adjacent ultrafiltration devices 2 can be sequentially increased, and the number of the ultrafiltration cores in the ultrafiltration device 2 closest to the reverse osmosis high-pressure pump 5 is the largest.
In specific implementation, the pretreatment of seawater comprises the following steps: sequentially feeding water to be treated into an ultrafiltration device through an ultrafiltration feed pump, and removing suspended matters in seawater through the ultrafiltration device; sea water desalination: the water produced by the ultrafiltration device is pressurized by a reverse osmosis high-pressure pump and then is sent into the reverse osmosis device, and the salt in the seawater is removed by the reverse osmosis device.
The foregoing is a more detailed description of the invention, taken in conjunction with the accompanying preferred embodiments, and it is not intended that the invention be limited to the specific embodiments described above. To the utility model belongs to the technical field of ordinary technical personnel, do not deviate from the utility model discloses under the prerequisite of design, can also make a plurality of simple deductions or replacement, all should regard as belonging to the utility model discloses a protection scope.
