In recent years, along with expanding economy, the fresh water dosage of demand is increasing; And the rivers,lakes and seas of China are generally polluted, and seven big water systems are except that the Zhujiang River and the Changjiang river; Other water system water quality are many in IV class and V class; The coastland, groundwater mining causes seawater intrusion, salinization problem in soil is also serious day by day; Want water to the sea this moment, and the development desalination technology has been subjected to general attention.
Sea water desaltination is to remove salinity in the seawater and obtain the technological process of fresh water through sea water desalinization equipment.At present, the method for sea water desaltination mainly contains distillation method and embrane method.Along with the raising of film properties, the improvement of HPP and the raising of energy recovery efficiency, the embrane method sea water desaltination is used more and more widely, and reverse osmosis membrane becomes the method that fresh water is produced in investment economizes most, cost is minimum sea water desaltination.
Reverse osmosis technology is adopted in the embrane method sea water desaltination, it utilize semipermeability can film, under the effect of pressure, make water in the salt solution see through semipermeability can film, and salinity and impurity are retained down, thereby reach the purpose that desalinizes seawater.
The water device is produced in existing embrane method sea water desaltination, and with the entrance end of seawater through the pressure vessel for reverse osmosis of HPP importing sea water distiling plant, the water of output only goes out from a termination of putamina.Under the common situation, the about 100～500mg/L of saltiness, the hardness that water is produced in the sea water desaltination of one-level embrane method lower (about 2～10mg/L), boron is higher, and (about 0.5～1.0mg/L), this water quality can't satisfy the requirement of tap water, can only satisfy the requirement of process water basically.According to GB 5749-2006 (drinking water sanitary standard), the ultimate value＜0.5mg/L of boron adopts the first-stage reverse osmosis embrane method to produce water and just can not reach this standard.If will reach drinking water standard, then need through after converting with the reservoir ditch, after perhaps the product water of one-level sea water desaltination being handled through two-pass reverse osmosis again, pass through activation treatment again after, be used for tap water.
Summary of the invention
The purpose of the utility model will overcome the existing in prior technology deficiency exactly, provides a kind of embrane method sea water desaltination to produce the water device, can make the product water of one-level embrane method sea water desaltination can satisfy the requirement of process water, can satisfy the tap water requirement again.
For realizing above-mentioned purpose; The water device is produced in the embrane method sea water desaltination that the utility model designed; Comprise the reverse osmosis membrane pressurized vessel that a plurality of parallel connections are provided with; The shell two ends of each reverse osmosis membrane pressurized vessel are respectively arranged with sea intake and dense water out; Also be provided with a pipe core that runs through in each reverse osmosis membrane pressurized vessel, series connection is provided with a plurality of reverse-osmosis membrane elements on the pipe core, and a plurality of reverse-osmosis membrane elements link to each other with the inner chamber of pipe core through the permeability hole that is opened on the pipe core; It is outer and link to each other with industrial water pipe that pipe core extends the reverse osmosis membrane pressurized vessel near an end of dense water out, and pipe core extends the reverse osmosis membrane pressurized vessel near an end of sea intake and links to each other outward and with the Drinking Water pipe.
Preferably, be provided with the manual valve and the pneumavalve of dominant discharge on said industrial water pipe and the Drinking Water pipe.Like this, can regulate the flow of Drinking Water through pneumavalve and manual valve according to the disposition of sea water desaltination.
Preferably, the cross-sectional area of said industrial water pipe is 2.5～5 times of cross-sectional area of Drinking Water pipe.Like this, the flux values of control Drinking Water pipe accounts for below 30% of gross output discharge, and the fresh water of can assurance obtaining can satisfy the tap water requirement fully.
Preferably, series connection is provided with 4～6 reverse-osmosis membrane elements in the said reverse osmosis membrane pressurized vessel.Like this, can effectively improve the product water efficient of reverse osmosis membrane pressurized vessel.
Being provided with 6 reverse-osmosis membrane elements with series connection in the reverse osmosis membrane pressurized vessel is example, and the water inlet saltiness and the product water saltiness variation tendency that detect reverse-osmosis membrane element are following:
The 1st reverse-osmosis membrane element is near the sea intake end of reverse osmosis membrane pressurized vessel, and its pressure P is the highest, TDS is minimum for the seawater saltiness, i.e. the water inlet saltiness C of first reverse-osmosis membrane element
1Be worth minimum; The 6th reverse-osmosis membrane element is near the dense water out end of reverse osmosis membrane pressurized vessel, and pressure P is minimum, TDS is the highest for the seawater saltiness, i.e. the water inlet saltiness C of the 6th reverse-osmosis membrane element
6Be worth the highlyest, the water inlet saltiness of six reverse-osmosis membrane elements progressively increases, and promptly its mathematical relation is C
1＜C
2＜C
3＜C
4＜C
5＜C

P1＜C
P2＜C
P3＜C
P4＜C
P5＜C
P6Higher saltiness means higher osmotic pressure Pc, so the impellent (P-P of seawater
c) progressively reduce.Product water pressure near the sea intake end of reverse osmosis membrane pressurized vessel is higher, and water quality is better, can be used as tap water; Product water pressure near the dense water out end of reverse osmosis membrane pressurized vessel is lower, and it is relatively poor relatively to produce water water quality, but the about 300～800mg/L of its saltiness, still can satisfy the needs of process water.Test shows that first three reverse-osmosis membrane element boron content＜0.5mg/L can satisfy the requirement of tap water.
The beneficial effect of the utility model: utilize one-level embrane method desalting equipment to produce water; Pipe core through the reverse osmosis membrane pressurized vessel connects the Drinking Water pipe near the sea intake end can realize that the index of boron in the product water of one-level embrane method desalination reaches the tap water requirement; Need not convert with the reservoir ditch; Need not carry out two-pass reverse osmosis yet and handle, reduce cost of investment and running cost.
