Description
Technical field
The utility model relates to a kind of comprehensive utilization of deep seawater.Be specifically related to a kind of system of extracting concentrated liquor from water at deep layer of ocean.
Background technology
The supply at healthy drinking water water source, deep-sea must be from seawater.And the deep-sea healthy drinking water mainly utilizes and effect is mainly derived from mineral element in the seawater.Therefore we at first roughly have gained some understanding to the mineral salt composition of seawater.
The various salinities of dissolving are seen that with its source seawater should contain elements all on the earth, but are limited to the analytical technology level in the seawater, have only measured kind more than 80 at present, and these elements constitute various organism and inorganics in the seawater.Though it is many to be dissolved in the chemical element of seawater, its content difference is very big.Except the hydrogen and oxygen of forming water, the unit of content more than 1mg have 12 kinds altogether in chlorine, sodium, magnesium, sulphur, calcium, potassium, bromine, carbon, strontium, boron, silicon and fluorine in every kilogram of seawater.They account in the seawater 99.9% of whole elements, they have formed 5 kinds of positively charged ion Na+, k+, Ca2+, Mg2+ and Sr2+, and 6 kinds of negatively charged ion Cl-, SO42-, Br-, HCO3-, CO32-and F-, totally 11 kinds of ion components are called macroelement and main component in the seawater.Because the content of these compositions in seawater is bigger, the ratio approximately constant between each constituent concentration, biological activity is little to its concentration affects, and character is more stable in seawater, is called conservative element again.Though but Si content wherein surpasses 1mg/kg, because its content is subjected to the influence of biological activity bigger, character is also unstable, does not belong to conservative element.Tens kinds of elements except that 12 kinds of macroelement are commonly referred to as trace element.Phosphorus, nitrogen, silicon etc. are called nutritive element to the relevant element of marine plant growth, when its content is very low, can limit the normal growth of plant, and it is significant to the ocean comprehensive utilization to study these element changes in distribution.The leading ion composition sees Table 1 in the seawater.

The dense water that reverse osmosis is come out is removed the material of 5000-10000 molecular weight in the water through ultra-fine filter 10, the electrodialysis unit 19 that removes sodium-chlor with specialization, remove sodium-chlor more than 80% and part bromide in the dense water, promptly obtain the concentrated solution of lower concentration, equally also use 80 ℃ temperature disinfection, be finished product after canned.
Mechanical filter 3 is primarily aimed at suspended particulate, partial organic substances, colloidalmaterial in the water and holds back and remove.Therefore the filtrate in the mechanical filter 3 mainly adopts marble, quartz sand, titanium sand, Tao Li material that water is handled, the particle requirement physical strength height that it is selected for use, and chemical property is stable, the burn into capacity of resisting impact load of anti-seawater is strong.
Owing to contain some protozoons, algae, various microorganism in the seawater, the processing of therefore killing livestock when deep seawater is handled is a critical step.Traditional brine disposal technology is dosing coagulant and chlorhexidine-containing disinfectant in seawater usually, because these materials have disadvantageous effect to the water quality of deep seawater, so this technology mainly adopts ozonizer 4 and activated charcoal filter 5, can kill the various biologies in the water on the one hand, ozone can decompose some organism in the seawater on the other hand, is beneficial to charcoal absorption and removal.
Security personnel's strainer 7 belongs to micro-filtration, and it is to use pressure is the screening process of power, and it belongs to secondary filter, promptly adopts microfiltration membrane, and general 0.05～10 μ m of its pore diameter range is characterized in filtering the precision height, filtering velocity is fast, adsorptive capacity is little, a day medium comes off etc.
Because pretreated filtering accuracy is relatively poor, the secondary pollutant that some macromolecular organism or water treating equipment and pipeline form also enters into condensed water along with the process of desalination, therefore adopts 10 pairs of condensed water of the high ultra-fine filter of filtering accuracy to filter.Ultra-fine filter 10 adopts ultra-filtration membrane, this ultra-filtration membrane generally can molecular weight cut-off be 103～106 material, compare with the processing of routine, design is easy to stdn, operation is easy to automatization, save advantages such as energy consumption and manpower, particularly the colloidalmaterial of concentrated solution can be reduced effectively, the particle of some mineral salt is removed effectively.
Sterilization equipment-be Sterilizers, deep seawater is heated to 85～90 ℃ and keeps 20～30min in electric-heating container.
The underpressure distillation device of level Four underpressure distillation device-each grade all adopts water cooling, and the negative pressure state that reaches that vacuumizes is distilled.Therefore vacuum pump needs water coolant could farthest carry out work when work, and the temperature of general recirculated water is controlled at 10～20 ℃
Removing sodium-chlor electrodialysis unit-cardinal principle and be with the direct current is impellent, utilizes anion-exchange membrane and cationic exchange membrane that the sodium ion in the deep seawater and chlorion, sulfate ion are removed.This electrodialyzer that removes sodium-chlor has stronger specific aim to the sodium-chlor in the water, the Na in the water
+To cathode direction migration, the H that comes out with water decomposition
+Forming NaOH flows out from negative electrode; And the Cl in the water
-And SO
4 2+The OH that comes out with water decomposition
-Become HCl and HSO
4From anode, flow out.After circulating repeatedly, the Na in the water
