Background technology
Nanofiltration is a kind of to be received between the reverse osmosis pressure-driven membrane separating process between ultrafiltration, its pore diameter range several
Rice or so, since it is poor less than 200 rejection to organics to monovalention and molecular weight, and to divalence or multivalent ion and divides
Organic matter of the son amount between 200~500 has higher removal efficiency, thus is widely used in electronics, food, medicine, biology hair
The industries such as ferment.
At present, the structure type of most of NF membranes is rolling, and the filtering runner of the structure is small, is easily blocked.Industrializing
In application, rolling NF membrane is statically placed in pressure vessel, thus during system operation, the material such as some microorganisms, organic matter holds very much
Easily formed on the surface of film dirty stifled, it is necessary to take considerable time and manpower cleaning.Rolling nanofiltration system is also required to higher charging
Flow velocity and operating pressure, thus energy consumption is of a relatively high.
At present, also there are some rotation cross-flow membrane separation devices, by allowing membrane component dynamic operation, reduce film table
The dirt in face is blocked up, such as：In patent《Spinning disk tablet membrane separation device》In disclose a kind of rotary membrane separation device, lead to
A rotatable quill shaft is crossed, drives the plate membrane being fixed on axis to rotate, one is formed in film surface in a manner of centrifugal movement
Fixed section flow velocity filters to realize.The membrane module antipollution of this structure type, energy consumption is low, but flat membrane component filtering accuracy
It is low, it is not pressure-resistant, it can only accomplish micro-filtration and ultrafiltration rank at present.
Therefore, it is necessary to the nanofiltration filtration apparatus of a kind of antipollution, low energy consumption to solve the problems, such as this.
The content of the invention
The object of the invention is to provide a kind of rotary organic nanofiltration membrane filtration apparatus, to solve traditional coiled nanofiltration device
High energy consumption, it is easy to pollute the problem of.
What the present invention was realized in：A kind of rotary organic nanofiltration membrane filtration apparatus, including hollow shaft, pressure vessel,
Flow guiding disc, organic nanofiltration membrane piece, dynamic seal, motor；The organic nanofiltration membrane piece of some central openings is folded up and is led into some
In flow table, integrally pierce into a hollow shaft, hollow shaft one end attaching nut locking, the other end passes through the method for pressure vessel ends
Blue plate is simultaneously interlocked with motor.Dynamic seal is installed, to prevent feed liquid from leaking between hollow shaft and flanged plate.Flanged plate is close to electricity
Motivation side is equipped with two mouths, and upper end is material liquid outlet, and lower end is liquor inlet, and hollow shaft goes out through motor side for filtrate
Mouthful, hollow shaft is communicated with equipped with aperture with organic nanofiltration membrane piece filter layer.
Pressure vessel is installed on flanged plate close to flow guiding disc side, just forms rotary organic nanofiltration membrane filtration apparatus.
The hollow shaft structure is thin for both ends, middle thick, and one end of hollow shaft interface pressure vessel closes and equipped with outer
Screw thread, the hollow shaft other end is hollow and is internal thread, and the hollow parts of hollow shaft are extended at flow guiding disc from internal thread side.
The pressure vessel is pressure resistant type, and 25 kilograms of allowable stress, pressure vessel is provided with pressure gauge at termination, with prison
Examining system internal pressure.
The water conservancy diversion panel surface has uniform and staggered arrangement salient point.In order to more preferably clamp diaphragm.
The organic nanofiltration membrane piece shares three layers, respectively film layer, clathrum, film layer, organic nanofiltration membrane piece surface structure
Can be polygon or circle, filtering accuracy 1-10nm.
The dynamic seal is pressure resistant type mechanical seal, shares two sets, is respectively interior mechanical seal and outer mechanical seal.
It is hole among the motor, hollow shaft can be therethrough.Motor can pass through Frequency Converter Control rotating speed.
Beneficial effect, the present invention provide a kind of rotary organic nanofiltration membrane filtration apparatus, to solve traditional coiled nanofiltration dress
Put high energy consumption, it is easy to pollute the problem of.When device is run, by an exterior high-pressure pump, hold from feed inlet by feed liquid pump-in pressure
In device, while motor is opened, and drives flow guiding disc and diaphragm rotation, and due to rotary motion, feed liquid forms a table in film surface
Face tangential force, so as to fulfill filtering.Dope in container is discharged from discharge port, and permeate is then collected into hollow shaft, finally along clear
Liquid collecting pipe is discharged.
It is organic in the device operational process the present invention provides a kind of antipollution, the nanofiltration filtration apparatus of low energy consumption
Nanofiltration diaphragm is kept in motion all the time, thus opposite traditional coiled nanofiltration, and resistance tocrocking is stronger, and inflow requirement is lower, uses
Longer life expectancy, while the final cycles of concentration (concentration) of feed liquid can improve, and improve operational efficiency.Solves tradition
Rolling nanofiltration device high energy consumption (it is required that pressure of higher), it is easy to pollute the problem of.Apparatus of the present invention provide film with rotary motion
Surface current speed, it is only necessary to which the high-pressure pump of a low discharge provides filter pressure, and traditional coiled nanofiltration system needs to be equipped with big flow
High-pressure pump, thus the device more saves energy consumption.
