Description
Technical field
The present invention relates to the Microwave photocatalytic wastewater degradation device expansion method of a kind of agglomeration tendency self-detection, belong to C02F
Technical field of waste water processing.
Background technology
Microwave and photo catalysis degradation treatment technology, as a kind of effective for the harmless treatment skill containing organic pollution industrial wastewater
Art, the most interesting.
About microwave and photo catalysis degradation technique, as an example, may refer to the Chinese patent Shen of Publication No. CN102260003A
Please case.
The disclosure number is the Chinese patent application case of CN102260003A, is using microwave as excitaton source, excites electrodeless ultraviolet lamp
Launching ultraviolet, irradiate the suspension mixed with photocatalyst titanium dioxide in liquid internal, this electrodeless ultraviolet lamp is by quartz ampoule institute cage
Cover protects, and is free air pump persistently to inject air to this quartz ampoule inner chamber, quartz cavity the air overflowed via pipeline be positioned at anti-
Answering the micro porous aeration head UNICOM bottom device, the lower zone of this inside reactor is aeration zone, the upper area of this inside reactor
Being microwave and photo catalysis reaction zone, the program also with the membrane separation assemblies that reactor is built-in, carries the water after analysis purifies, and with this film
Separation assembly realizes retaining of photocatalyst titanium dioxide fine particles and uses;The program also non-polar ultraviolet light source and membrane separation assemblies it
Between set up dividing plate, for preventing the ultraviolet radiation damage to organic membrane separation assemblies;It is passed through the air of inside reactor,
Part the most directly participates in relying on the photocatalytic degradation of photocatalyst titanium dioxide to react, some air, direct at ultraviolet light
Under irradiation, generating a certain amount of ozone, the ozone of this generation the most also plays the direct oxidative degradation for organic pollution
Effect.
The disclosure number is that the Chinese patent application case of CN102260003A is certainly for microwave and photo catalysis wastewater degradation technology
Progress serves very important impetus, and the work that its research staff is launched in this field is admirable.
Meaning based on sincere admiration, and, common striving direction, to be talked below us is problem.
The problem below will spoken of, has 11;These 11 problems are arranged side by side 11 problems;The priority of its sequence
Consider easily merely for the sake of discussing.
One of problem:
The disclosure number is the Chinese patent application case of CN102260003A, and it divides for the film intercepting catalyst titanium dioxide fine particles
It is to be placed in reactor inner chamber from assembly, is immersed among process object liquid, and relies on washing away containing ozone bubbles of ascension
Membrane separation assemblies, the institute's catalyst particles that adsorbs, be detained that thereby removes its surface, reach the recovery of catalyst particles, recycling
Purpose, meanwhile, it is self-cleaning and keep its separating power that membrane separation assemblies is also dependent on this mode, then, based on this structure, only
Business curtain hollow fiber film assembly or plate film assembly can be selected, and, this membrane separation assemblies is to need to be immersed in ozone
In the context of the strong oxidizing property of bubble ascension, therefore, the tolerance against oxidative power of membrane separation assemblies is necessarily required, common material
The organic membrane separation assembly of matter is not resistant to such use environment, therefore can only select the membrane separation assemblies of PVDF material, this
Point clearly illustrates in the 0009th section of word of this case disclosure and claim 3;This kind needs special tolerance against oxidative power
Its material of filter membrane is relatively costly, and its commercially available price is certainly also above common organic micro-filtration membrane module of non-oxidation durability requirements;Change
Sentence is talked about, and the frame mode of this case causes the material of membrane separation assemblies to be limited to PVDF material costly.Further, dress
Putting interior possible ultraviolet light to reveal, may touch organic membrane assembly, this organic membrane assembly material also required that in device can be resisted
Ultraviolet light irradiation, from the point of view of this, organization plan based on this device, the material of organic membrane separation assembly also can only be limited in
PVDF material costly.
Organic membrane assembly, compared to ceramic filter assemblies, has its obvious advantage;About this point, special for filtering technique
For the personage of industry, it is known, does not the most launch to repeat.
So, under the premise using organic material membrane module, this PVDF filter membrane material limitation can be bypassed?This is
One needs the problem solved, and this is one of problem.
The two of problem:
In view of scouring force, the cleaning capacity of described ascension bubble are more weak, therefore, with this cleaning mode with the use of membrance separation
The filter opening aperture of bigger microfiltration rank can only be selected in its aperture of assembly, and the filter opening aperture of this microfiltration rank is 0.1-0.2 micron,
About this point, have in the 0009th section of word of this case disclosure and claim 3 equally and clearly limit, this kind of filter opening aperture
Limit, from the type selecting of the such membrane separation assemblies of this case, built-in and soak from the point of view of occupation mode, the self-cleaning method of ascension bubble, be
Inevitable, its filter opening aperture can only be limited in microfiltration rank.In other words, this in the way of ascension bubble washes away its scouring force,
Cleaning force is the most weak, to such an extent as to cannot tackle the filter membrane of more small-bore at all, and thus, in this case device, filter sizes limits
Between 0.1 micron-0.2 micron, it it is the inevitable choice not discussing leeway.
The filter opening aperture of so-called 0.1-0.2 micron, if changing a measurement unit, corresponding is exactly the filter opening hole of 100-200 nanometer
Footpath;That is any concept?For 100 nanometer filter opening apertures of its lower limit, its size of catalyst particles that it can intercept
Must be more than 100 nanometers, and cannot be intercepted less than the catalyst particles of 100 nanometers;In other words, less than 100
The catalyst particles of nanometer by being directed through, by the filter opening of membrane module, be mixed into so-called water purification that degradation reaction device exported it
In.
Need now to have a talk the particle diameter of photocatalyst involved by ultraviolet catalytic degradation reaction and photocatalyst dosage form selection.
The professional person being engaged in photocatalytic degradation research both knows about, and reacts with the photochemical degradating of uv light induction, and its catalyst is many
Select titanium dioxide fine particles catalyst;At present, laboratory level has been developed for various in style urging based on titanium-dioxide photo
Changing the light degradation particle catalyst of characteristic, certainly, the light degradation catalyst that these different preparation methods are formed, its particle diameter is also
It is various;Its particle diameter of photocatalyst that different preparation methoies are made is little to 20 nanometers, greatly to 100000 nanometers namely 100 microns,
Have, be wherein no lack of the photocatalyst kind of excellent performance;But, due to performance long-time stability evaluate, preparation cost and
The restriction of market expansion etc. aspect factor, most of its deliverability of described photocatalyst is limited only to laboratory level,
And do not have to form the most commercially available level of production;The most known can make a big purchase in large quantities commercially available can be actual a large amount of
The photocatalyst for ultraviolet light wave band used is famous gas phase titanium dioxide P25;Its concrete skill of gas phase titanium dioxide P25
Art implication, insider both knows about, and does not the most launch to repeat;The mean diameter of gas phase titanium dioxide P25 is 21 nanometers;Gas
Phase titanic oxide P25 performance not very optimum, but, its stable performance, it is important to can commercially make a big purchase in large quantities and obtain, and
Can use the most in a large number, therefore, the most usually be used as weighing respectively with P25 catalyst in photocatalysis specialized laboratory
Plant reference pointer or the contrast pointer of self-made photocatalyst catalytic performance, it is true that in view of the feature of ultraviolet catalytic degradation reaction,
The photocatalyst that dispersion is the highest, is suitable for the needs of this type reaction, say, that mean diameter is at the light of 21 ran
Catalyst its catalyst interfacial area that can provide, anti-settling ability, catalytic performance long-time stability etc. aspect, comprehensive and
Speech, is optimal.Simply, at present, good and cheap, it is possible to the actual ready-made commercially available business making a big purchase in large quantities, using
The photocatalyst of the ultraviolet light wave band of grade, it is simply that mean diameter is the gas phase titanium dioxide P25 catalyst of 21 nanometers;In industry
The application of scale, this mean diameter be the photocatalyst of 21 nanometers be actual first-selection.
Already described above and, the disclosure number is the Chinese patent application case of CN102260003A, and it is for intercepting the film of photocatalyst
Assembly, is the catalyst particles that stripping film assembly surface adsorbs, deposits that washes away with ascension bubble, but, this kind is to rise
Rise its scouring force of mode that bubble washes away, cleaning force the most weak, to such an extent as to the filter membrane of more small-bore cannot be tackled at all, therefore,
In this case device, filter sizes is limited at microfiltration filter opening rank between 0.1 micron-0.2 micron, for changing a measurement unit,
In this case device, filter sizes is limited at the microfiltration filter opening rank between 100 nanometer-200 nanometers, and this is not discuss leeway
Inevitable choice;This case certainly cannot intercept as above flat without the microfiltration filter opening between selectable 100 nanometer-200 nanometers
All particle diameters are the gas phase titanium dioxide P25 granule of 21 nanometers;So, if using P25 photocatalyst, this catalyst will completely
Cannot intercept, and flow in so-called water purification, form secondary pollution, certainly also result in the heavy losses of catalyst and unrenewable;
Even if using the titanium dioxide optical catalyst of the big particle diameter special for this of other kind, it collides because of mutual during using
Or collide with wall, inevitable also can produce a large amount of small particle fragment, wherein particle diameter is less than the fragment of 100 nanometers, equally can not be by
Microfiltration filter opening between 100 nanometer-200 nanometers is intercepted, these fractionlets also can through its membrane module enter so-called water purification it
In, form secondary pollution.
Visible, the disclosure number is the Chinese patent application case of CN102260003A, and it is for the interception structure of photocatalyst microgranule
The cleaning solution of scheme and related film assembly is the most undesirable.
Therefore, how under the premise of this case advantage of incorporating things of diverse nature, reach the fine interception for photocatalyst microgranule and return
Receiving use again, be a important topic the most worth thinking deeply about, this is the two of problem.
The three of problem:
It is known that liquid water body itself also is able to absorb the energy of microwave, and cause the liquid water body that is processed itself
Temperature-rise effect, and this with wastewater treatment process the temperature-rise effect that occurs, be not the most our situation of being expected, in other words
Saying, the microwave energy from magnetron is used for exciting electrodeless ultraviolet lamp the most completely, and has quite a few should be served only for swashing
The microwave energy sending out electrodeless ultraviolet lamp is dissipated in described temperature-rise effect, and it is unnecessary that the temperature-rise effect that this kind is not fond of causes
Microwave energy waste, in view of disclosed above number be CN102260003A the apparatus structure side that shown of Chinese patent application case
Case, its rational approach, can only be to reduce single tank process capacity in other words by the volume of minimizing microwave and photo catalysis reactor to come
Reach the purpose weakening the unnecessary dissipation of microwave, about this point, in this its detailed description of the invention of CN102260003A application case
Clearly have expressed the suitable size overall about this apparatus structure, what its expressed preferred size was corresponding is exactly that a profile is the least
Device, then, consequently, it is possible to the distance of reactor wall and microwave radiation source is little, the wastewater flow rate contacted with microwave is little,
The microwave energy that waste water is absorbed is the least, corresponds ground, and the wastewater treatment capacity of single tank is the least, more specifically
Ground is said, the internal capacity corresponding to device suitable size expressed in embodiment is 40 liters, namely single tank wastewater treatment capacity is
40 liters, i.e. 0.04 cube, in other words, its once a complete set of, substantial length of operation solve only the industrial wastewater of 0.04 cube, then,
Being accomplished by the repetition operated by a complete set of head to tail carried out many times, the cumulative of its treating capacity just has plant-scale meaning,
So to say, the most individual analogy substantially, 0.04 cube of such waste water of single tank that its preferred structure size of this case is generally corresponding to
Treating capacity, need to repeat 1000 times by a complete set of head to tail, substantial length of operation, its accumulation amount, can be only achieved 40 cubes such one
Individual have industrial level wastewater treatment capacity, the most loaded down with trivial details repetitive operation will cause the serious waste of human and material resources,
Visible, the wastewater degradation treatment effeciency of its reality of scheme that this kind is shown by CN102260003A may not be fully up to expectations.
Therefore, how on the premise of not causing the waste of more microwave energy or reducing microwave energy waste, increase single tank wastewater treatment capacity,
Reduce the unnecessary too many by the repetitive operation number of times of head to tail of this batch (-type) wastewater treatment equipment, improve its waste water and process effect
Rate, is a significant technical problem merited attention.
On the other hand, according to the literature, some system, in the case of microwave direct irradiation wastewater liquid, photochemical catalysis is dropped
Solve efficiency and truly have raising, say, that in some system, between microwave direct irradiation wastewater liquid and photochemical catalysis degraded,
There is certain coupling.
Therefore, how on the premise of taking into account described coupling, improve the treatment effeciency of wastewater degradation device, be worth inquiring into,
This is the three of problem.
The four of problem:
The scheme that this kind is shown by CN102260003A, the bubble of the internal unrestrained cloth ascension of its retort, for driving a reaction tank
The shuttling movement of the relatively large yardstick of internal liquid, contributes the most inadequate;Certainly, this weak point, for CN102260003A
In scheme such as its detailed description of the invention the fact that clear expression for upper corresponding small size, low capacity device, almost without what
Observable impact.From the point of view of plant-scale application demand, undersized can not the device of divergence process amount certainly the most much
Captivation;So, as a kind of probability, if there being certain mode to be capable of the significantly expansion for the treatment of capacity, under this situation,
Its importance of shuttling movement of the relatively large yardstick of retort internal liquid will highlight naturally;Imagine the most this process
The probability that amount is significantly expanded, then, how to strengthen the shuttling movement of the relatively large yardstick of retort internal liquid, be certainly exactly
Individual problem, this is the four of problem.
The five of problem:
For the photochemical catalysis oxidation reaction of ultraviolet light wave band, this kind of oxidation is anti-to have the most several following key element to influence whether
The efficiency answered, first ultraviolet wavelength, intensity, it two is photocatalyst in the particle diameter of photocatalyst, unit volume reactant liquor
Usage amount, himself catalytic performance etc. of photocatalyst, it three is organic concentration in oxidized object i.e. water body, has
Oxidation complexity that machine thing molecular structure is determined himself etc., it four is the sufficient degree of oxygen atmosphere, in other condition
In the case of identical, the sufficient degree of oxygen atmosphere, will become and affect an act foot of photochemical catalysis oxidative degradation ability gently
The key element of weight.
The scheme shown such as CN102260003A, its numerous micro porous aeration heads being placed in reactor inner chamber bottom overflow cloth the end of at
Portion, and by its alleged water distributing plate so that this micro porous aeration head overflows the effect of cloth arrangement and becomes more very, certainly, this for
For using the situation of oarse-grained micron-sized photocatalyst of relatively easy sedimentation, really there is its favourable one side, but,
From the point of view of another side, this micro porous aeration head overflows the mode that cloth arranges, and the supply of oxygen atmosphere excessively disperses, and needs most
The region that need to strengthen oxygen supply is the most effective region of photochemical catalysis oxidation, due to effective in liquid water body of short wave ultraviolet
Penetration depth only has 20 cm, therefore, needs most enhanced oxygen blowing real with the effective coverage promoting photochemical catalysis oxidation course
It is exactly the region within quartz ampoule periphery about 20 cm distance on border, in other words, within quartz ampoule periphery about 20 cm distance
Region be the region really needing the supply of enriched with oxygen atmosphere to ensure, oxygen atmosphere supply in this region is the strongest, and oxidation reaction is also
Just it is proceeded more quickly;The most especially, producing electrodeless ultraviolet emission in microwave excitation mode, its feature can be accomplished greatly exactly
Power, high intensity, this is the strong point of this lamp-type of electrodeless ultraviolet lamp, but, just because of its purple extraradial high power, high-strength
Degree, just mates with greater need for powerful oxygen atmosphere supply capacity, and otherwise, that powerful ultraviolet radiation energy power is just
Really major part is wasted.Above it is stated that, the scheme shown such as CN102260003A, factors limits
Its reactor size, limits its actual treatment capacity, as its specific embodiment clearly illustrates, that
Can be a single tank single treatment amount little reactor that only has about 40 liters, in the case of such little reactor, little inner chamber,
Because size is the least, then, its shortcoming in terms of photochemical catalysis oxidation effective coverage oxygen supply concentration degree, would not
The most obvious, it might even be possible to ignore, a problem the most non-existent can be regarded the most completely as, in the face of such
Undersized little reactor, the shortcoming problem in terms of oxygen supply concentration degree, not may float mind;However, it is contemplated that
Once, if described many limiting factors can be overcome, if can have that way actual implementation one is large-scale, high throughput anti-
Answer device, then within above-mentioned quartz ampoule periphery 20 cm distance, effective coverage oxygen supply strengthening problem will show especially out, particularly with
Using electrodeless ultraviolet lamp as the situation of UV source, within above-mentioned quartz ampoule periphery 20 cm distance, effective coverage oxygen supply is strengthened
Problem is not more allowed to despise, therefore, how among the structure of possible large-scale photo-catalytical oxidation degradation reaction device,
Strengthen the oxygen supply concentration degree of described effective coverage, improve the usefulness of wastewater degradation equipment, it is simply that the problem that individual needs are kept a close watch on, this is
The five of problem.
The six of problem:
Within this CN102260003A scheme pumps air into the quartz ampoule including electrodeless ultraviolet lamp, reach the logical of electrodeless ultraviolet lamp
Wind cooling, the purpose of cooling, and those flowings are through the air of quartz ampoule, because of by ultraviolet irradiation, some air meeting
Being changed into ozone, therefore, the air flowed out from quartz ampoule is exactly the air containing some ozone certainly, and this is contained smelly by the program
Oxygen air is transferred to be positioned at micro porous aeration head below reactor, and disengages from micro porous aeration head, these containing ozone bubbles from lower
On ascension during, ozone contained therein can meet with the organic molecule that runs among distance and redox reaction occurs,
This redox reaction can consume a part of ozone certainly, this be do not have doubt, but, above it is stated that, as
The scheme that CN102260003A is shown, the many factors that cannot ignore certainly existed limit its reactor size,
Limiting its actual treatment capacity, as clearly illustrating in its specific embodiment, that can only be a single tank single
Treating capacity only has the little reactor of about 40 liters, in the case of such little reactor, little inner chamber, because overall dimension itself
The least, then, the longitudinal size of its reactor inner chamber or regard as with reckoning in every item contain the liquid degree of depth also can only be one the least
Size, clearly illustrates among this size such as its detailed description of the invention, the most about 40 centimetres, and the Sheng that reckons in every item liquid is deep
Spend the most only 40 centimetres, actually contain the liquid degree of depth and be certainly less than this number, just analyze with the Sheng liquid degree of depth of 40 centimetres, that
, this Sheng liquid degree of depth of 40 centimetres is what concept?That is to say, containing ozone-air ascension by the path of waste water only
Having short 40 centimetre, this path is the shortest, passes through at a gallop containing ozone-air bubble and only only has 40 centimetres of deep water bodys,
The shortest for time of contact with water body, contained in bubble ozone, can only have small part to be used for oxidative degradation Organic substance,
And most ozone actually simply passes by liquid simply, effusion emptying through exhaust port from liquid level, briefly,
The Oxidation potentiality major part of these ozone is wasted, and, effusion, the ozone that is wasted actually can cause need not
The air pollution wanted;This case main inventive people once beat via micro porous aeration head with normal domestic use ozone machine in one meter of deep tank
Enter containing ozone-air, in the case of the depth of water degree of depth reaches one meter, remain able to substantially smell the abnormal smells from the patient of ozone near the water surface, can
See, that 40 centimetres of deep Sheng liquid degree of depth, it is clear that be to be not enough to fully utilized ozone;Visible, electrodeless ultraviolet light chemistry is urged
For changing the such equipment of wastewater degradation reactor, ozone utilizes incomplete problem to be also required to pay close attention to, it is clear that Ren Mengeng
It is contemplated that the reactor of wastewater degradation without extreme ultraviolet that ozone utilizes more completely, contaminative exhaust emissions is less, this is the six of problem.
The seven of problem:
Its running of waste water catalytic degradation reaction device, requires the expenditure of energy, and therefore, operator are bound to wish, work as wastewater degradation
When reaction proceeds to terminal, it is possible to impartially, the most lately immediately stop continuing to inject to inside reactor
Energy;If the moment stopping Implantation Energy is too early, then wastewater degradation is incomplete;And if reaching reaction end already, the most still
The most unceasingly to inside reactor Implantation Energy, that is certainly the energy in waste preciousness.As this case technical background
Its structure of CN102260003A scheme can not provide any instant information to the wastewater degradation reaction end moment, then, just
The terminal that wastewater degradation reacts can only be estimated by experience;And estimate, by experience, the terminal that wastewater degradation reacts, that obviously can not
Satisfactory;So, how to make neither the most undelayed instant information output for the wastewater degradation reaction end moment,
And immediately close the energy input to reactor in the just right moment, it is simply that a technical threshold that can not despise, this is
The seven of problem.
The eight of problem:
Accept the described industrial wastewater of microwave and photo catalysis degradation treatment, be mingled with some the most unavoidably and originate from mechanical system abrasion process
The material of metal particle and carbon granules etc, even if quantity is small, its existence is almost difficult to avoid that, the disclosure number is
Described organic membrane separation assemblies in the Chinese patent application case of CN102260003A is installed in microwave and photo catalysis reaction zone, its
In be installed between quartz ampoule and membrane separation assemblies certainly do not stop microwave for intercepting the dividing plate of ultraviolet, so, micro-
The practical function region of ripple necessarily covers organic membrane separation assemblies institute installation area described in the program, based on membrane separation assemblies
Working mechanism, its accumulation process on membrane separation assemblies organic matter top layer of the microgranule of metal particle as above and carbon granules etc
It is difficult to avoid that, and the microgranule of this type of described metal particle and carbon granules etc, exactly the good absorption medium of microwave energy, inhale
The microgranule of described metal particle and the carbon granules of having received the accumulation state of microwave energy etc, its organic plasma membrane being close to can be divided by nature
Produce from the top layer of assembly and based on heat penetration erosion mechanism lasting pierce destruction, be as noted previously, as this CN102260003A
The structures shape of its device of application case can only select polyvinylidene fluoride film material, this polyvinylidene fluoride film material heatproof about 140 degrees Celsius,
More certain than general film material heatproof high much, but, described metal particle and carbon granules of absorbing the accumulation state of microwave energy etc
Its point-like of microgranule pierce the heat penetration erosion effect of formula and the most easily break through the heatproof temperature limit of this polyvinylidene fluoride film material, due to above-mentioned former
Cause, well imagines, the pvdf membrane material in this its device of CN102260003A application case its actual life will be the lowest
In the preferable service life expected, the structure of this CN102260003A its device of application case, determine in this structural frames
Under frame, above-mentioned point-like pierce formula heat penetration erosion destruction problem cannot avoid;Therefore, how to get around this point-like and pierce the heat penetration erosion of formula
Destruction problem, also needs to consider, and this is the eight of problem.
The nine of problem:
The disclosure number is the Chinese patent application case of CN102260003A, the 0008th section of word of its description disclosure text
And claim Section 2, the catalyst particle size scope being suitable for for its device, there is a restriction, this particle size range limits
It is that 20 nanometers are to 100 microns.It is known that some pH value be pre-adjusted not in place, pH value inappropriate in the case of,
Titanium dioxide fine particles is susceptible to reunite, and then affects its effective working interface area, affects its photocatalysis usefulness;Particularly with
The section of those the relatively small particle diameters among this particle size range, easily occurs because of presetting not in place, the pH value of pH value not especially
Appropriate and the agglomeration traits that causes: for this catalyst particles in the case of of reuniting, is immediately to adopt an effective measure, enters
The depolymerization of aggregate is operated by the hand-manipulating of needle;But, we, among this CN102260003A scheme, do not see any having
Help immediately dissolve the structure of this problem or can immediately dissolve the scheme prompting of this problem.For such as
CN102260003A scheme can only be the reactor of small scale structures because factors limits just like that, still can the most directly carry
React device, carries out toppling over and inspecting outside reactor, process above-mentioned reunion situation, then, hold if likely expanding it
Amount, the most so to say, if being the several cubes of large-scale reactors to dozens of cube or huge reactor, that is the most not
It is manual to topple over it and operate the problem that can tackle, then, for this catalyst particles in the case of of mutually reuniting, how
Realize instant disposal in situ, it is simply that a technical problem, this is the nine of problem.
The ten of problem:
The disclosure number be CN102260003A Chinese patent application case expressed by apparatus structure in, protect electrodeless purple for screen
The quartz ampoule of outer lamp, its outer wall, refer to the outer wall of quartz ampoule, through for a long time with the contacting, unavoidably of processed industrial wastewater
Gradually dirty, the material that dirt amasss the most mainly is difficult to the mineral-type impurity touched by light-catalyzed reaction, because of the formation of this mechanism
Dirty phenomenon, is easy to be observed after equipment long-play;It is attached to the dirty lamination of described quartz ampoule outer wall, although
The veryyest thin one layer, also be enough to cause the ultraviolet radiation of electrodeless ultraviolet lamp significantly stop, and this will cause this microwave light to be urged
The actual treatment effect changing reaction treating device significantly reduces;In its reactor, the bubble of unrestrained cloth ascension is because excessively disperseing, scouring force
Measuring more weak, if only relying on this more scattered bubble to maintain the bright and clean of quartz ampoule surface, really undertaking to do what is apparently beyond one's ability, in other words
Saying, this more scattered bubble, what it was more weak wash away strength is still not enough to stop completely the dirty process on this quartz ampoule surface;?
During the use of laboratory yardstick, above-mentioned fouling problem is subtle, but, on commercial Application yardstick, this fouling problem
Certainly will highlight;Therefore, how on the premise of not tearing machine open, immediately, effectively remove on this quartz ampoule outer wall
Dirt lamination, maintains the lasting high efficiency of this microwave and photo catalysis processing means, and this problem is the most very important, and this is the ten of problem.
The 11 of problem:
Nine its problems derived of this problem problem by addressing above.Above speak of, some pH value be pre-adjusted less than
In the case of position, pH value are inappropriate, titanium dioxide fine particles is susceptible to reunite, and then affects its effective working interface area,
Affect its photocatalysis usefulness;Particularly with among its suitable catalyst particle size range that this CN102260003A scheme is touched upon
The section of those relatively small particle diameters, easily occur especially because of pH value presetting not in place, pH value is incorrect and the group that causes
Poly-problem;For this catalyst particles in the case of of reuniting, it is immediately to adopt an effective measure, carries out for aggregate
Depolymerization operates;Based on this its framework of CN102260003A scheme, operator cannot immediately perceive inside reactor and institute occurs
State the situation of reunion, thus also cannot make instant disposal, thus, should be limited by factors and can only be small scale structures
Its limited usefulness of reactor can reduce further;Therefore, among the application of reactor operates, particularly, for example,
Among the application of possible large-scale reactor or huge reactor operates, the most immediately awareness inside reactor catalyst particles
The main inducing parameter reunited, is a key issue, and this is the 11 of problem.
Summary of the invention
The technical problem to be solved is, with CN102260003A scheme as technical background, for address above
One of this its existing problem of technical background scheme, two, three, four, five, six, seven, eight, nine, ten, 11, and hold concurrently
Turning round and look at collaborative, the coupling of microwave exposure excitation and photochemical catalysis degraded, research and development one can solve this series totally and ask
The new method of topic.
The present invention solves described technical problem by following scheme, and the program provides the microwave light of a kind of agglomeration tendency self-detection to urge
Changing wastewater degradation device expansion method, the key step of the method is as follows: a, with the microwave exposure spatial domain of the caged of metal material
The quartz ampoule that its inner bay is provided with electrodeless ultraviolet lamp is wrapped up by constrainer so that the microwave exposure that quartz ampoule is in this caged is empty
The inside of region constraint device, the locations of structures of microwave exposure spatial domain its entirety of constrainer of this caged is in wastewater degradation reactor
Portion, the microwave exposure spatial domain constrainer of the caged of this metal material is exactly a metal cage, is a mass of hole in its structure of this metal cage
Hole or mesh, the function of the microwave exposure spatial domain constrainer of this caged is to retrain therein, microwave exposure spatial domain thereby at cage
Build microwave weak irradiation spatial domain between outer wall and the inwall of reactor of the microwave exposure spatial domain constrainer of shape or microwave zero irradiation is empty
Territory;B, probes into the inside of wastewater degradation reactor by the waveguide being derived from magnetron, and this waveguide is probeed into wastewater degradation

It is an advantage of the invention that the microwave exposure spatial domain to wastewater degradation inside reactor carries out forcing partition, this case metal cage
Electrodeless ultraviolet lamp and screen thereof being protected shrouds in it with quartz ampoule, and metal cage retrains the effect spatial domain of microwave simultaneously, so, at quartz
Spatial domain between pipe outer wall and metal cage inwall defines the wastewater degradation region of a microwave and photochemical catalysis coupling, and
And, the multiple hole of metal cage or the structure of many meshes, do not affect waste water and reactor bottom bubbling and on air freely into and out of
This spatial domain;And the spatial domain between metal cage and reactor wall, the simple pyrogenicity of microwave is absorbed by waste water water body to be contained,
The most significantly weaken the unhelpful dissipation of microwave energy;This case method forces the microwave exposure cutting off wastewater degradation inside reactor empty
Territory, based on this, this case method allows by significantly expanding this design volume without microwave exposure spatial domain, it is achieved one-pot reaction body
Long-pending significantly expansion;This case method allows reactor list tank wastewater treatment capacity to be substantially improved, and need not worry that microwave energy is too much again
Dissipate in unhelpful waste water water body temperature-rise effect.
Relying on this case method, the most single tank wastewater treatment capacity of the design volume of wastewater degradation reactor can be expanded to several cubes to number
Ten cubes;The volume of hundreds of cubes of even single tank, is also to allow;Rely on this case method, expand reactor for treatment capacity
After, a complete set, the frequency of omnidistance wastewater degradation equipment operation, the beneficially saving of human and material resources can be greatly reduced.
This case method is on the premise of taking into account described microwave and photochemical catalysis coupling, and for relevant wastewater degradation reactor, it sets
The significantly expansion of meter capacity provides a broad space.
On the other hand, this case method makees the shuttling movement of relatively large yardstick with described circulation guide guided liquid-flow, rises in reactor
The liquid stream that can pull, guide inside reactor containing ozone bubbles stream risen along the inner passage rapid increase of this circulation guide,
And impact, by microwave and photo catalysis coupled reaction region after, by top area to surrounding spread, via neighboring area sink,
Arrival reactor intracavity bottom region, then the inner passage of guide is converged to circulate through circulating the horn mouth of guide, continue it
Circulation;The liquid shuttling movement of this relatively large yardstick guided, contributes to guaranteeing inside reactor liquid degradation reaction process
Homogenization, this, for large-scale degradation reaction device, is necessary.
Its UV source of this case method is to rely on microwave excited electrodeless ultraviolet lamp, and the ultraviolet radiation feature of this lamp-type is exactly permissible
Accomplish high-power, high intensity, but the Effective depth penetration that ultraviolet is in liquid water body only has about 20 centimetres, therefore, stone
Region within English pipe periphery about 20 cm distance is effective coverage, and this region is exactly photochemical catalysis oxidative degradation
Efficient region;This case method is with described circulation guide, and pack is from the bubble stream of numerous micro porous aeration heads so that it is concentrate
Ground discharges towards quartz ampoule peripheral light chemical catalytic oxidation effective coverage, and the method is favorably improved effective district described in quartz ampoule periphery
The oxygen atmosphere supply intensity in territory, helps speed up ultraviolet catalytic oxidation degradation reaction process.
Can significantly expand based on this case method, the capacity of reactor or treating capacity, described significantly expand, be by significantly expanding
The design volume of microwave zero irradiation zone or the weak irradiation zone of microwave realizes, then, the lateral dimension of reactor, longitudinal ruler
Very little is all significantly to expand certainly, and therefore, inside reactor is contained the liquid degree of depth and can be deepened significantly similarly, such as, and can
To deepen to one meter, two meters, three meters, four meters, five meters, six meters, even ten meters, etc., containing the feelings that the liquid degree of depth is the deepest
Under condition, containing ozone-air bubble ascension path long enough, steep the time long enough contacted with water body, its ascension process containing ozone-air
In just can be with abundant reducing substances fortune, and thoroughly or be close to and exhaust ozone contained in bubble up hill and dale, thus,
Incomplete problem is utilized to be solved containing ozone composition oxidation potential in ozone-air bubble, and, due to long
Ascension path cause ozone depletion, reactor tail gas re-entrainment would not have the ozone that can cause environmental pollution.
This case method is with external multistage filter, reaches little from aggregate bulky grain to ten number nanometer to catalyst particles
The interception step by step of the collision fragment of yardstick, is close to recovery, reuse photocatalyst up hill and dale, is close to and takes precautions against catalyst loss up hill and dale
And the secondary pollution caused;This hold-up interception method secondary filter can be protected to make its filtration passage from bulky grain thing step by step
The rigid obstruction of matter;Wherein the pre-filtering aperture of the first order is between 5 microns and 300 microns, and its aperture of the microfiltration of the second level exists
Between 25 nanometers and 1000 nanometers, its aperture of the ultrafiltration of the third level is between 15 nanometers and 2 nanometers;Such hold-up interception method,
Can fully intercept nano level photocatalyst, it can be close to interception gas phase this average particle of titanium dioxide P25 up hill and dale certainly
Footpath is the catalyst of 21 nanometers;Address above, the gas phase titanium deoxide catalyst of nano level P25 etc, be can be a large amount of
The commercially available catalyst buied, is also durability, stability, the known excellent photocatalyst of ultraviolet light wave band photocatalysis performance,
Certainly, it is also the photocatalyst in fact paying the utmost attention in industrial scale applications select;This case catalyst hold-up interception method and catalyst
The practical capacity of market supply, actual kind match, blend.
Further, in this case method, it is external mechanism that catalyst intercepts mechanism, and based on the method, its filter element need not be soaked in reaction
In Strong oxdiative within device, the liquid of strong ultraviolet irradiation, therefore, it can need not consider completely ultraviolet irradiation, Strong oxdiative condition
Tolerance, so, just without the restriction in terms of extraordinary tolerance in the selection of filter element material, can more vast
Select in selection matter kind, and entirely without the material of the PVDF must being confined to again costly etc.
Involved filters at different levels are commercially available, commercially available filters at different levels, the discharge of draining-off sewage when its sewage draining exit is exactly backwash
Mouthful, this case uses this kind of back flush type equipment, is used to intercept step by step catalyst particles, the sewage draining exit of the most commercially available relevant device,
The recycling delivery outlet or backflow that are used as by retaining catalyst particles by conversion in this case method use delivery outlet again.
Already described above and, can significantly expand based on this case method, the capacity of reactor or treating capacity, described significantly expand, be
Realized by the design volume significantly expanding microwave zero irradiation zone or the weak irradiation zone of microwave, then, from the appearance,
The lateral dimension of reactor, longitudinal size are the most all significantly to expand, and therefore, inside reactor contains the liquid degree of depth similarly
Can deepen significantly, for example, it is possible to deepen to one meter, two meters, three meters, four meters, five meters, six meters, even ten meters, etc.
Deng, in the case of the Sheng liquid degree of depth is enough deep, containing ozone-air bubble ascension path long enough, the bubble containing ozone-air contacts with water body
Time long enough, just can be with abundant reducing substances fortune during its ascension, and thoroughly or be close to and exhaust up hill and dale
Ozone contained in bubble, thus, utilizes incomplete problem to obtain containing ozone composition oxidation potential in ozone-air bubble
Thoroughly solve, and, owing to long ascension path causes ozone depletion, reactor tail gas re-entrainment would not have and can cause
The ozone of environmental pollution;Only when being subject to processing reducing substances in water body i.e. organic pollution is degraded totally, in water body
Through again without being available for the organic pollution of ozone oxidation reaction, those unnecessary ozone it is possible to no longer consume and pass through long
Ascension path effusion liquid level;Having spoken of, among the some problem that this case solves simultaneously, is enhanced reactor
The circulation of the relatively large yardstick of internal liquid, the systemic circulation mechanism that this enhances facilitates the organic dirt contained by it of inside reactor liquid
The uniformity of dye thing degradation reaction process, thus, several cubes allowed at its corresponding framework of this case method are stood to dozens of
Under the process capacity framework of the most hundreds of the cube volume in side, when inside reactor ullage has ozone effusion, i.e. show
The degradation reaction of inside reactor has reached terminal, and be internal liquid entirety uniformity reach the terminal of degradation reaction, this
One terminal point determining factor is the matching criteria that can be provided by with this case scheme;This case fills in its exhaust port position of reactor
If ozone sensor, ozone detected in this locations of structures, just mean that inside reactor degradation reaction is reached home, ozone
Sensor and the composite structure connection with ozone attention device or ozone content display or ozone attention device and ozone content display
Connect, for providing the information that indicates accurately, this case and the electric signal by ozone sensor output to be passed by cable to operator
Giving power-supply controller of electric, this power-supply controller of electric is also coupled with magnetron and air pump respectively by cable, and power-supply controller of electric is according to it
Received described electric signal carries out on and off switch action, and certainly, its function mode is to receive ozone at power-supply controller of electric
When the signal of the ozone effusion that sensor sends, it is automatically switched off and leads to magnetron and the power supply of air pump;This case method according to this,
The terminal of inside reactor degradation reaction process can be known in time;And method according to this, when reaction reaches terminal, it is automatically switched off magnetic
Keyholed back plate and the power supply of air pump, stop to inside reactor Implantation Energy in time, so can avoid unnecessary energy waste;And
And, this case method according to this, when degradation reaction is reached home, it is possible to close described magnetron and the power supply of air pump in time,
This power-off action also synchronizes, the same generation process terminating in a flash ozone, owing to ozone generation process is terminated in time,
The a large amount of ozone that would not have more than needs disengage from described exhaust port, thus avoid unnecessary secondary pollution or say secondary
Raw pollution;This case method determines the ozone that its corresponding framework do not has more than needed and is available for discharge.
Relying on this case method, the microwave exposure spatial domain of inside reactor is cut off by forcing, limits, this case and use external level
Join multistage backwash filter and carry out the fine interception for catalyst particles, among this method, back flush type doughnut microfiltration
Membrane module and back flush type polysulfone hollow fiber ultrafiltration membrane system are all by external and away from reactor core, and microwave can not be irradiated to institute completely
Stating membrane module, based on this case the method, got around described point-like completely and pierced the heat penetration erosion destruction problem of formula, this problem thus obtains
To good solution.
