Description
Technical field
The utility model relates to a kind of efficient, energy-conservation membrane separation device, belongs to separation technology field.
Background technology
The filtration, the clarification that contain the fluid liquid of solid particles (solid phase particles, microorganism, big molecule) are technical process common among the human production activity.Usually way is to let fluid pass through porous filter medium, comprises filter silks, filter cloth etc.Above-mentioned solid matter just is blocked in the filter medium surface, and the fluid that flows through filter medium is purified and clarifies.Traditional mode is that so-called end-blocking filters; Fluid flows through medium under the effect of gravity or impressed pressure, the solid suspended particles are held back gathering on the filter medium surface, and its thickness increases in time and is compacted; Thereby blocked the further quick seepage flow of fluid, so that had to stop filter operation; Filter efficiency was very low when its solid leached thing and is colloid and ultrafine particle, and operation must be step, remove filter cake termly, cleaning filter membranes or disposable abandoning (as under the situation of filter silks).Based on this principle, developed many industrial filters, for example plate-frame filtering is being fixed filter medium (being generally fabric property filter cloth) on a series of sheet frames, can improve the efficient that solid-liquid separates through the mode of pressurization extruding.Problem is to remain intermittently operated, and work difference and intensity are big, and because filter medium is general reticulated, tends to occur phenomenons such as leakage filter, thereby also be a kind of poor efficiency, low-quality liquid-solid separate mode.
Membrane separation technique has appearred in the eighties of last century 60-70 age, promptly adopts the porous film material of organic polymer or inorganic to realize this solid-liquid separation process.The difference of this film and aforesaid filter cloth, filter silks is that special pore structure is arranged, thereby can obtain higher separating power and effect.Can be divided into micro-filtration membrane (membrane aperture is more than 100nm), milipore filter (aperture is less than 100nm) and NF membrane (aperture is 1-2nm) based on the pore size difference.In lock out operation practice, separated solid-liquid mixtures under the driving of pump with the flow through passage of tubulose membrane component of certain speed, liquid under the transmembrane pressure effect that pump provides (for example.The ceramic-film tube internal pressure is 3-5atm, if stream tapping side atmosphere, then pressure is 1atm) go out through fenestra seepage flow.Because liquid is flow at high speed (crossflow velocity is 4-6m/s usually) on the film surface, because the existence of tangential force, solids are difficult to form filter cake from the teeth outwards, and the boundary layer thickness that concentration polarization forms is very thin, thereby filtration decays very slow in time.In this filter type, fluid flow direction is vertical with seepage direction, is commonly referred to cross flow one or cross-flow.Filter with end-blocking and diversely to be; One of great advantage of this mode of operation is can continued operation, large-scale application; Thereby be widely used in numerous industrial civil areas such as fruit drink, medical and health, chemical industry metallurgical, biotechnology, energy environment protection, water treatment and obtained huge technical economic benefit, and in constantly its application of developing.
The utility model content
The utility model rationally keeps and draws the speciality of end-blocking filtration and cross-flow filtration for the big characteristics of film separating area in the unit volume of utilizing the film resolution element, avoids shortcoming separately, has proposed a kind of comprehensive film lock out operation pattern.
The present invention adopts following technical scheme to achieve these goals:
Efficiently, energy-conservation membrane separation device; Comprise raw material tank, settling tank; It is characterized in that: described raw material tank bottom adopts separating pipe to be communicated to the upper shed of settling tank, is provided with first valve, liquid feeding pump, second valve in the middle of the described separating pipe successively, crosses element kit, the 3rd valve, and the described filter core sidewall of crossing is provided with the filtrating pipeline; Flowmeter and the 4th valve are installed on the described filtrating pipeline; The described mistake between filter core and the 4th valve is provided with recoil equipment, and described recoil equipment lower end is communicated with the filtrating pipeline and is provided with the 5th valve, and described raw material tank sidewall also adopts reflux line to be communicated with the settling tank sidewall; Be provided with the 6th valve in the middle of the said reflux line, described settling tank bottom is provided with the deposit outlet that has the 7th valve.
Described efficient, energy-conservation membrane separation device, described raw material tank and settling tank are in co-altitude so that the liquid in the settling tank flows in the raw material tank, so that get back to the film separation process.
Described efficient, energy-conservation membrane separation device, described separating pipe are higher than settling tank and carry out the film separation so that raw material has high pressure.
The beneficial effect of the utility model:
(1) saved the pump cycling of feed liquid, not only reduced equipment investment but also can cut down the consumption of energy greatly.
(2) in principle can any component connection in series-parallel design, improve space availability ratio greatly, and all component, no matter up and down, front and back all have the same function of overstating film pressure thereby can giving full play to film.
(3) owing to be static end-blocking filter process basically, can suitably improve and overstate film pressure, fully improve the withstand voltage advantage of ceramic membrane, the flux of elementary membrane area can significantly improve, thereby can further reduce membrane area and equipment investment.
(4) owing to there is not the long-time flow at high speed of liquid, thereby phenomenons such as temperature rise and solid suspension be broken can not appear.
(5) the high solids content feed liquid in the technical process is discharged in the special settling tank; Because what the normal orientation filtration time discharged than dope and the time of backwash process is long is many; Settlement action has adequate time to carry out; Supernatant can pump in fluid reservoir, this with regard to reasonable use the gravitational settling effect, further saved the energy.
(6) start-up time of same reason recoiling device is shorter than the low time of one crossflow membrane filtration efficient; Such recoiling device can be used for many film filters simultaneously; In other words can use low power recoil equipment, thereby equipment and operating cost are further saved.
