Detailed description of the invention
It as it is shown in figure 1, the present embodiment is based on the modularization oxygenerator of doughnut ceramic oxygen-permeable membrane, is by several
Hollow fiber perineurium element 16 is dismountable is installed in parallel in high temperature furnace 14 composition；Corresponding to each hollow fiber membrane bundle element
16, it in high temperature furnace, has all been independently arranged heating unit, so that each hollow fiber membrane bundle element can work alone.Specifically set
When putting, heating unit can use resistive heater 15.
As in figure 2 it is shown, hollow fiber membrane bundle element 16 includes that shell the 3rd, upper cover the 2nd, several one end seal other end opening
Doughnut ceramic oxygen-permeable membrane membrane tube the 4th, perineurium firm banking 11 and perineurium fixed disk 10；
Wherein, upper cover the 2nd, shell 3 and perineurium firm banking 11 coordinate from top to bottom successively, form closed structure；At upper cover 2
Central authorities offer air intake 1, the central authorities at perineurium firm banking 11 offer oxygen outlet 12, open in the downside of shell 3
It is provided with air outlet slit and air outlet slit joint 5 is installed；
The inside bottom of perineurium firm banking 11 is trapezoidal mesa structure；Perineurium fixed disk 10 lies against perineurium firm banking
It (is stuck in trapezoidal table top superstructure) in 11, between the bottom of bottom and perineurium firm banking 11, form inverted trapezoidal cavity；
Offering some through holes on perineurium fixed disk 10, laminating above perineurium fixed disk is fixed with ceramic fiber paper 8,
Ceramic fiber paper 8 also offers and through hole through hole one to one on perineurium fixed disk 10；
Each doughnut ceramic oxygen-permeable membrane membrane tube 4 is inserted vertically into fixing ceramic fiber paper 8 He down one by one with openend
The through hole of perineurium fixed disk 10 is interior and extend out in inverted trapezoidal cavity；Above ceramic fiber paper 8, perineurium firm banking 11 with
Pass sequentially through organic fluid sealant 7 between each doughnut ceramic oxygen-permeable membrane membrane tube 4 and carry out double-layer seal with inorganic sealant 6.
Oxygen outlet 12 connects oilless vacuum pump.
Concrete, high temperature furnace 14 is provided with perineurium element bracing frame 13, the boss shape of hollow fiber membrane bundle element 16
Upper cover 2 is suspended on perineurium element bracing frame 13, so that hollow fiber membrane bundle element 16 is fixed in high temperature furnace 14.Hollow is fine
The air intake 1 of dimension perineurium element 16 and air outlet slit joint 5 are all positioned at outside high temperature furnace 14.
Shell 3 is threaded engagement with coordinating of upper cover 2, and shell 3 is threaded engagement with coordinating of perineurium firm banking 11, and
Sealed by elastic washer.It is threaded engagement between air outlet slit joint 5 and described shell 3.
The assembling of the above-mentioned modularization oxygenerator based on doughnut ceramic oxygen-permeable membrane, occupation mode are exemplified below:
Perineurium fixed disk 10 is kept flat in perineurium firm banking 11, then spread one layer of ceramic fiber paper 8 on its surface, will
Through hole on ceramic fiber paper 8 and the through-hole alignment on perineurium fixed disk 10, to ensure doughnut ceramic oxygen-permeable membrane membrane tube 4 energy
Penetrate, be fixed in perineurium fixed disk.The openend of doughnut ceramic oxygen-permeable membrane membrane tube 4 is passed through downwards ceramic fibre one by one
Paper is inserted vertically in the array through-hole of perineurium fixed disk, adds organic encapsulant 7, and organic encapsulant needs certain flowing
Property, the temperature of 200-400 DEG C is stablized and can be born in solidification, after organic encapsulant solidification, adds inorganic sealant at an upper portion thereof

Mouth 12 external oilless vacuum pumps, carry out air-leakage test, if extracting out without gas, illustrate that air-tightness is intact, if there being air to extract out, then
The inorganic sealant of secondary addition, repeats, until fully sealing.Elastic washer 9 is enclosed within outside perineurium firm banking 11, so
Rear screw-in shell 3, shell 3 and perineurium firm banking are threaded.Upper cover 2 screws in shell 3, and shell 3 and upper cover 2 are similarly
Threaded, preliminarily form hollow fiber membrane bundle element 16.Hollow fiber membrane bundle element 16 is passed through perineurium element bracing frame 13
Put in high temperature furnace 14, upper cover 2 edge torr on perineurium element bracing frame with fixing.Air outlet slit joint 5 is screwed in shell 3 side
In the tapped through hole of face, complete the assembling of single perineurium element.
As procedure described above by some hollow fiber membrane bundle elements assemble be fixed on perineurium element bracing frame 13, then from
Air intake 1 is passed through air.Each element air outlet slit joint connects follow-up emission-control equipment, discharges gas in order to collect process
Body.Connection oilless vacuum pump is collected, in order to produce low oxygen partial pressure ring after each oxygen outlet 12 quality of connection flowmeter and breather valve
Border and oxygen are collected.
During work, heat up and reach operating temperature (700～900 DEG C), open oilless vacuum pump, can produce in inner chamber and film
Raw low oxygen partial pressure environment, thus carry out oxygen processed.Determine gas bleeding flow by incoming gas flow gauge.Also can connect gas phase look
Spectrometer, in order to inspect gas bleeding oxygen content by random samples, in order to carries out oxygen quality monitoring.If element operationally goes wrong, then
Changes in flow rate can be detected by gas flowmeter, after closing breather valve, change to damaging element.
Through on probation, with one with 10 a diameter of Φ 2mm, the Ba of a length of 40cm0.5Sr0.5Co0.8Fe0.2O3-δ(BSCF)
The oxygen flow element of hollow-fibre membrane composition, when 900 DEG C, oxygen speed is at 150cm3/min.Calculate by this, single 48 BSCF
The oxygen production capacity of perineurium element can reach 720cm3/min.If the assembly of 10 element compositions, total oxygen production capacity can reach
7.2dm3/ min, per hour can oxygen 0.43m processed3.This assembly can use oxygen demand regulating element quantity according to different, assembles, ties up
Protect and be very convenient to, it is possible to achieve producing continuously, there is very high efficiency.
