Description
Technical field
The invention belongs to technical field of sewage treatment equipment, the high multiple continuous film of a kind of modularization concentrating unit particularly is provided.
Background technology
R-o-be a kind of be impellent with the pressure difference, from solution, isolate the membrane sepn operation of solvent.Feed liquid to film one side is exerted pressure, and when pressure surpassed its osmotic pressure, solvent can be made inverse osmosis against the direction of naturally osmotic.Thereby the solvent that obtains seeing through in the low-tension side of film, i.e. penetrating fluid; The high-tension side obtains spissated solution, i.e. liquid concentrator.If use the reverse-osmosis treated seawater, obtain fresh water in the low-tension side of film, obtain bittern in the high-tension side.
Reverse osmosis membrane is core parts of realizing r-o-, is a kind of artificial semi-permeable membranes with certain characteristic that biological semi-permeable membranes is processed of simulating.Generally process, like CAM, aromatic polyamide film with macromolecular material.Therefore the membrane pore size of reverse osmosis membrane is very little, can remove dissolved salts in the water, colloid, mikrobe, organism etc. effectively.
The reverse osmosis membrane assembly form has tubular fibre formula, rolling, flat and tubular type.The commercialization assembly that can provide in the market mainly contains the coiled reverse osmosis membrane assembly and high-voltage flat board-like (dish tubular type) reverse osmosis membrane assembly.
Because to have process simple in r-o-, compact construction, fitting operation is easy, and energy consumption is low, and it is high to produce quality, advantage such as can operate at normal temperatures, is developed rapidly in recent decades.At present large-scale application in seawater and brackish water desalination, BW is softening and every field such as waste water advanced processing.And the constantly expansion of its range of application, begun to be used for concentrating of dairy products, fruit juice and separating and concentrated aspect of biochemistry and biotechnological formulation.
Nf membrane belongs to the semi-permeable membranes of r-o-category, and its aperture is between r-o-and ultra-filtration membrane, and it is several to several nanometers to be often referred to zero point.Nf membrane is held back organic molecular weight and is about about 200-800MW, and the molecular weight hundreds of is arrived several thousand material, and it is fine to hold back effect.Compare with reverse osmosis membrane, nf membrane has the effect that selectivity is held back to ion, and the clearance of solubility univalent ion is lower than high valence ion.
Nanofiltration generally is used for removing organism and the pigment of surface water, hardness and other high valence ion in the underground water, and part is removed the dissolving monovalent salt.In food and medicine production nanofiltration be used for useful matter extraction, concentrate.In recent years, nanofiltration has obtained fast development in the application of industries such as chemical industry, pharmacy, food-drink, water treatment, environment protection.
Industrialized reverse osmosis membrane and nanofiltration membrane component form mainly contain two kinds: a kind of is rolled membrane module, and another kind is flat (dish tubular type) membrane module.
Rolled membrane module is that existing market is used film application form at most the most widely, and its major advantage is that to load density big, uses easy and simple to handlely, and industry standard is unanimity relatively.The rolled film element is rolled by flat sheet membrane and forms, and has comprised assemblies such as dull and stereotyped diaphragm, charging graticule mesh, penetrating fluid graticule mesh, glue and permeate collection pipe, and the wherein common rolled film element that is used for industrial separation also carries the anti-twisting equipment at two ends.Receive the influence of structure and material, general rolled membrane module maximum operating pressure is no more than 4.2MPa, the sea water desaltination membrane module, and the highest working pressure is no more than 8.3MPa.
Rolled membrane module requires high to water inlet, antifouling property is poor, be not easy to recover after polluting, but its filling area is big, and water production rate is big, and low price generally is used for the spissated prime of high power and handles, and cycles of concentration generally is no more than 5 times.
Flat (dish tubular type) membrane module has been broken the mindset of rolled film design on component construction, adopted flat diaphragm structure.Have following characteristics on flat (dish tubular type) membrane module structure and the flow process: 1. by withstand voltage flow guiding disc, the stacked and centre gangway pull bar of diaphragm is formed, and flow guiding disc is not pressed in that the O shape circle that places on the film bag surface around the central tie rod will intake and pure water separates.2. it is short that membrane element is gone into water flow passage, and 180 degree of generation continuously that flow turn to (each standard film post corotation is to 418 times) thereby eliminated concentration polarization.3. the spacing between the passage between film surface and the valve plate is more than 2mm, the unique design of this open type passage, even but make former water turbidity height to 80NTU works better still, so just can simplify pre-filtering.The passage of broad also can bear film surface liquid flow velocity faster, can reduce the possibility of concentration polarization greatly up to the film surface velocity of 0.4m/s.4. because the salient point on the valve plate causes the current on film surface to become turbulence state, make that the pollution and the fouling on film surface are few, membrane stability is high.Flat (dish tubular type) membrane module is at present except rolled film, the membrane element form of other a kind of uniqueness in the r-o-field.The unique design of dish tubular membrane element makes that the element intake pressure can be up to 20MPa.
Flat (dish tubular type) membrane module requires low to water inlet, but raw water turbidity up to 80NTU works better still, contamination resistance is strong, recovers easily after polluting, operating pressure is high, is suitable for very much the spissated back of high power level and handles.
The industrial continuous film concentrating unit of mass-producing mainly contains two kinds: a kind of two sections or multistratum system that adopts Christmas tree structure to arrange, another kind is two sections or a multistratum system of recirculation structure.
Christmas tree structure design: because a water inlet part of every section becomes product water; The flooding velocity that the back is one section can reduce; In order to guarantee the normal flooding velocity of every membrane element,, form the inverted pyramid shape and arrange so the pressurized vessel quantity of back segment is lacked than the pressurized vessel quantity of the preceding paragraph.Concrete arrangement mode is relevant with factors such as single pressurized vessel membrane element quantity, material properties (concentration, viscosity etc.), the design recovery.The arrangement mode of common four～six core membrane pressure vessels is 2:1 or 4:2:1.To multistratum system, because membrane element self pressure drop and concentration raise, the insufficient phenomenon of clean driving pressure can appear in the back segment system, and it is unbalanced to cause leading portion and rear end to produce water, often need between per two sections, add topping-up pump, to improve the motivating force of back segment.Christmas tree structure design film system recoveries rate can reach 50～80 %.The Christmas tree structure design advantage is a structure and simple to operate, reduced investment.The system of this structure only needs a HPP (needing intersegmental topping-up pump sometimes) and process line seldom and valve usually, and is simple to operation, is convenient to realize automatic control.Its disadvantage is to receive factor affecting such as material properties, the recovery, and the feed rate of membrane element selects can be in usually too high or too low edge, and the fluctuation of any feed rate all may cause system unstable.At present, two sections systems that nearly all industrial r-o-all adopts Christmas tree structure to arrange, former water is through behind this reverse osmosis system, and multipotency is concentrated 4-5 doubly.
The recirculation structure design: its maximum is characterised in that every section system all is equipped with a recycle pump, and feed pipe is connected to pump entry, and each section membrane stack outlet conduit also is connected to pump entry simultaneously.Recycle pump, membrane stack and associated conduit form a circulating inside circle.The effect of recycle pump provides every needed feed rate of pressurized vessel, overcomes mould and falls.The recirculation structure design is generally 2 above circulating ring parallel connections, the pump entry of each circulating ring and membrane stack concentrated solution outlet mounted valve.Its great advantage is that each circulating ring can be distinguished independent operating, through controlling each circulating ring terminal valve, is producing under unbroken situation, realizes cleaning, thereby realizes continuous concentration truly; In addition, owing to adopted inner circulation structure, system recoveries rate can reach very high (can reach more than 95%), and can on a large scale, adjust according to material properties and production needs.Recirculation structure design main drawback is that investment and working cost are high.Under the situation that cycles of concentration and processing speed are confirmed, hop count is few more, and employed membrane element can be many more.Increase hop count, though can reduce membrane element quantity, can increase the quantity of recycle pump simultaneously, installed power improves, and working cost increases.Influenced by the one-time investment expense, the recirculation structure design is generally used for the bigger system of treatment scale.Former water can be concentrated into more than 20 times through the reverse osmosis system of recirculation structure.The disclosed disc tube reverse osmosis (dt-ro) technology that is used for the percolate processing of Chinese patent CN200620001529.6 has promptly adopted the recirculation structure design.
At present, still there is not cycles of concentration to reach tens of times even hundreds of times continuous film concentrating unit, and increasing in the demand of advanced treatment of industrial waste water reuse and zero discharge of industrial waste water, press for a kind of high multiple continuous film concentrating unit of exploitation.
