Description

Initiatively the photochemical catalysis waste water of recognition reaction terminal point is degraded and is used the large vol reactor
Technical field
The large vol reactor is used in the photochemical catalysis waste water degraded that the present invention relates to a kind of active recognition reaction terminal point, belongs to the CO2F technical field of waste water processing.
Background technology
Microwave and photo catalysis degradation treatment technology, is quite paid close attention to effectively at the innoxious process for treating that contains the organic pollutant trade effluent in recent years as a kind of.
About the microwave and photo catalysis degradation technique,, can referring to publication number the Chinese patent application case of CN102260003A as an example.
The disclosure number is the Chinese patent application case of CN102260003A, be as excitaton source with microwave, excite electrodeless ultraviolet lamp emission ultraviolet ray, be mixed with the suspension liquid of photocatalyst titanium dioxide in the liquid internal irradiation, this electrodeless ultraviolet lamp is shrouded by silica tube to be protected, there is pneumatic pump to continue to inject air to this silica tube inner chamber, the air that is overflowed by quartzy chamber is via pipeline and the micro porous aeration head UNICOM that is positioned at reactor bottom, the lower zone of this inside reactor is the aeration zone, the upper area of this inside reactor is the microwave and photo catalysis reaction zone, this scheme is also with the built-in membrane separation assemblies of reactor, carry the water of analysing after the purification, and realize that with this membrane separation assemblies holding back again of photocatalyst titanium dioxide fine particles use; This scheme is also set up dividing plate between electrodeless ultraviolet light source and membrane separation assemblies, be used to prevent the radiation injury of ultraviolet ray to the membrane separation assemblies of organic matter; Feed the air of inside reactor, part is participated in the photocatalytic degradation reaction that relies on photocatalyst titanium dioxide directly, some air, under the direct irradiation of UV-light, generate a certain amount of ozone, the ozone of this generation is also being brought into play the direct oxidative degradation at organic pollutant certainly.
The disclosure is number for the Chinese patent application case of CN102260003A has undoubtedly played very important pushing effect for the progress of microwave and photo catalysis waste water degradation technique, and its research staff is admirable in this field institute unfolded work.
Based on the meaning of sincere admiration, and, the common striving direction, what will talk below us is problem.
Below the problem that will speak of has ten; These ten problems are ten problems arranged side by side; The priority of its ordering only is to consider for discussing easily.
One of problem:
The disclosure number is the Chinese patent application case of CN102260003A, its membrane separation assemblies that is used to tackle the catalyzer titanium dioxide fine particles is to be placed in the reactor inner chamber, be immersed among the process object liquid, and rely on the ozone bubbles that contains of ascension to wash away membrane separation assemblies, it is adsorbed to remove its surface by this, the catalyst particles that is detained, reach the recovery of catalyst particles, utilize purpose again, simultaneously, membrane separation assemblies also is to rely on this mode self-cleaning and keep its separating power, so, based on this structure, can only select for use commercial with curtain formula hollow fiber film assembly or plate film assembly, and this membrane separation assemblies is need be immersed in the context of strong oxidizing property of ozone bubbles ascension, therefore, oxidation tolerance to membrane separation assemblies must have requirement, the organic membrane separation assembly of common material can not tolerate such environment for use, so can only select the membrane separation assemblies of PVDF material for use, this point clearly illustrates that in open the 0009th section literal of text of this case and claim 3; Its material cost of the filter membrane of the oxidation tolerance that this kind needs are special is higher, and its commercially available price also is higher than common organic micro-filtration membrane module of non-oxidation tolerance requirement certainly; In other words, the frame mode of this case causes the material of membrane separation assemblies to be limited to expensive PVDF material.Have again, UV-light possible in the device is revealed, may touch the organic membrane assembly, this also the organic membrane assembly material in the claimed apparatus can resist ultraviolet light irradiation, from this point, based on the organization plan of this device, the material of organic membrane separation assembly also can only be limited in expensive PVDF material.
The organic membrane assembly has its conspicuous advantage compared to the ceramic filter assemblies; About this point, for the personage of filtering technique specialty, be known, here do not launch to give unnecessary details.
Can so, under the prerequisite of using the organic material membrane module, bypass this PVDF filter membrane material limitation? this is the problem that needs solve, and this is one of problem.
Two of problem:
Scouring force in view of described ascension bubble, cleaning capacity is more weak, therefore, can only select other filter opening aperture of bigger micro-filtration level for use with its aperture of membrane separation assemblies that this cleaning mode is used, other filter opening aperture of this micro-filtration level is the 0.1-0.2 micron, about this point, in open the 0009th section literal of text of this case and claim 3, have clearly equally and limit, this kind filter opening aperture limits, type selecting from the such membrane separation assemblies of this case, built-in and soak use-pattern, the self-cleaning method of ascension bubble, be inevitable, can only limit its filter opening aperture in the micro-filtration rank.In other words, this its scouring force of mode that washes away with the ascension bubble, cleaning power too a little less than, to such an extent as to can't tackle the more filter membrane of small-bore at all, thus, in this case device, the filter membrane aperture is limited between 0.1 micron-0.2 micron, is the inevitable choice of not discussing leeway.
The filter opening aperture of so-called 0.1-0.2 micron, if change a measure unit, corresponding is exactly the filter opening aperture of 100-200 nanometer; Is what notion that? with 100 nanometer filter opening apertures of its lower limit, its size of catalyst particles that it can be tackled must be more than 100 nanometers, and can't be blocked less than the catalyst particles of 100 nanometers; In other words, less than the catalyst particles of 100 nanometers will directly penetrate, by the filter opening of membrane module, sneak among the so-called water purification that the DeR device exported.
The particle diameter and the photocatalyst dosage form selection of the related photocatalyst of the ultraviolet catalytic DeR of need having a talk now.
The professional person who is engaged in photocatalytic degradation research knows, with the photochemical degradation reaction of uv light induction, its catalyzer multiselect titanium dioxide fine particles catalyzer; At present, on laboratory level, developed the photodegradation particle catalyst based on the optically catalytic TiO 2 characteristic various in style, certainly, the photodegradation catalyzer that these different preparation methods form, its particle diameter also is various; Its particle diameter of photocatalyst that different preparation methods make is little of 20 nanometers, to also promptly 100 microns of 100000 nanometers, has greatly, wherein is no lack of the photocatalyst kind of excellent performance; But because the restriction of the evaluation of performance permanent stability, preparation cost and market expansion or the like aspect factor, most its deliverabilities of described photocatalyst only are confined to laboratory level, and do not have to form extensive commercially available production level; At present known can make a big purchase in large quantities commercially available can actual a large amount of photocatalysts that are used for the UV-light wave band that use be famous gas phase titanium dioxide P25; Its concrete art-recognized meanings of gas phase titanium dioxide P25, the insider knows, does not here launch to give unnecessary details; The median size of gas phase titanium dioxide P25 is 21 nanometers; Gas phase titanium dioxide P25 performance is not very optimum, but, its stable performance, key is can make a big purchase in large quantities to obtain on market, and can on technical scale, use in a large number, therefore, in the photochemical catalysis specialized laboratory also usually with the P25 catalyzer be used as weighing various self-made photocatalyst catalytic performances with reference to pointer or contrast pointer, in fact, characteristics in view of the ultraviolet catalytic DeR, the photocatalyst that dispersity is high more, be fit to the needs of this type reaction, that is to say, the photocatalyst of median size about 21 nanometers its catalyst interfacial area that can provide, anti-sedimentation capacity, catalytic performance permanent stability or the like aspect, comprehensive, be optimal.Say simply, at present good and cheap, the photocatalyst of the UV-light wave band of the ready-made commercially available commercial grade that can actually make a big purchase in large quantities, use, be exactly median size be the gas phase titanium dioxide P25 catalyzer of 21 nanometers; At plant-scale application, this median size is that the photocatalyst of 21 nanometers is actual first-selections.
Above address, the disclosure number is the Chinese patent application case of CN102260003A, it is used to tackle the membrane module of photocatalyst, be to wash away the stripping film assembly surface adsorbed with the ascension bubble, sedimentary catalyst particles, yet, its scouring force of mode that this kind washes away with the ascension bubble, cleaning power too a little less than, to such an extent as to can't tackle the more filter membrane of small-bore at all, therefore, in this case device, the filter membrane aperture is limited at micro-filtration filter opening rank between 0.1 micron-0.2 micron, change a measure unit, in this case device, the filter membrane aperture is limited at the micro-filtration filter opening rank between 100 nanometers-200 nanometer, and this is the inevitable choice of not discussing leeway; The micro-filtration filter opening that this case does not have between selectable 100 nanometers-200 nanometer can't be tackled the gas phase titanium dioxide P25 particle that aforesaid median size is 21 nanometers certainly; So, if use the P25 photocatalyst, this catalyzer will can't be tackled fully, and flows in the so-called water purification, forms secondary pollution, certain heavy losses that also cause catalyzer and unrenewable; Even if use other kind for this reason and the titanium dioxide optical catalyst of special big particle diameter, collide because of mutual collision or with wall in its use, must also can produce a large amount of small particle size fragments, wherein particle diameter is less than the fragment of 100 nanometers, can not be tackled by the micro-filtration filter opening between 100 nanometers-200 nanometer equally, these small shredss also can see through its membrane module and enter among the so-called water purification, form secondary pollution.
As seen, the disclosure number is the Chinese patent application case of CN102260003A, and its cleaning scheme at the interception structure scheme of photocatalyst particulate and related film assembly is all undesirable.
Therefore, how under the prerequisite of this case advantage of incorporating things of diverse nature, reaching at the meticulous interception of photocatalyst particulate and reclaim usefulness again, is an important topic very worth thinking deeply about, and this is two of a problem.
Three of problem:
We know, liquid water body itself also can absorb the energy of microwave, and cause itself temperature-rise effect of processed liquid water body, and this temperature-rise effect of following wastewater treatment process and occurring, it but not the situation that we expected, in other words, microwave energy from magnetron is not used to excite electrodeless ultraviolet lamp fully, and have quite a few should only be used to excite the microwave energy of electrodeless ultraviolet lamp to be dissipated in described temperature-rise effect, the temperature-rise effect that this kind is not fond of has caused unnecessary microwave energy to waste, in view of above-mentioned publication number is the apparatus structure scheme that the Chinese patent application case of CN102260003A is showed, its rational approach, can only be to reduce the purpose that single jar of processing capacity is reached the unnecessary dissipation of reduction microwave in other words by the volume that reduces the microwave and photo catalysis reactor, about this point, clear suitable size of having expressed in this its embodiment of CN102260003A application case about this apparatus structure integral body, the preferred size correspondence that it is expressed be exactly a device that profile is very little, so, thus, the distance of reactor wall and microwave radiation source is little, the wastewater flow rate that contacts with microwave is little, waste water institute microwave energy absorbed is also little relatively, with it accordingly, single jar wastewater treatment capacity is therefore also little, more particularly, the pairing internal capacity of device suitable size expressed in the embodiment is 40 liters, also be that single jar of wastewater treatment capacity is 40 liters, promptly 0.04 cube, in other words, it is once a complete set of, substantial length of operation has only solved 0.04 cubical trade effluent, so, just need carry out many times by the repetition of head to the operation of the complete set of tail, adding up of its treatment capacity just has plant-scale meaning, so to say, just individual analogy roughly, single jar of 0.04 cube of such wastewater treatment capacity that its preferred structure size of this case is roughly corresponding, need to repeat 1000 times by the complete set of head to tail, substantial length of operation, its accumulation amount, just can reach 40 cubes such one have industrial level wastewater treatment capacity, so excessively loaded down with trivial details repetitive operation will cause manpower, the serious waste of material resources, as seen, this kind may not be fully up to expectations by its actual waste water degradation treatment efficient of scheme that CN102260003A showed.Therefore, how not cause more microwave energy wastes or to reduce under the prerequisite of microwave energy waste, increase single jar of wastewater treatment capacity, reduce the unnecessary too many of this intermittent type wastewater treatment equipment by the repetitive operation number of times of head to tail, improve its waste water treatment efficiency, be a significant technical problem that merits attention, this is three of a problem.
Four of problem:
This kind be by the scheme that CN102260003A showed, the bubble of the inner dispersed ascension of its retort for the cyclic motion of the relative big scale of driving a reaction jar internal liquid, is contributed inadequate slightly; Certainly, this weak point, in fact corresponding small size, the low capacity device of clear expression in CN102260003A scheme such as its embodiment, the influence that almost has nothing observable.From plant-scale application demand, undersized device that can not the divergence process amount does not have great magnetism certainly; So, as a kind of possibility, if there is certain mode can realize the significantly expansion of treatment capacity, under this situation, its importance of the cyclic motion of the relative big scale of retort internal liquid will highlight naturally; Imagining the possibility that this treatment capacity is significantly expanded, so, how to strengthen the cyclic motion of the relative big scale of retort internal liquid, is exactly a problem certainly, and this is four of a problem.
Five of problem:
Photochemical catalysis oxidizing reaction for the UV-light wave band, there is following so several key element can have influence on the efficient of this kinds of oxidation reaction, first ultraviolet wavelength, intensity, it two is particle diameters of photocatalyst, the usage quantity of photocatalyst in the unit volume reaction solution, himself catalytic performance or the like of photocatalyst, it three is that oxidized object is an organic concentration in the water body, oxidation complexity that the organic molecule structure is determined himself or the like, it four is sufficient degree of oxygen atmosphere, under the identical situation of other condition, the sufficient degree of oxygen atmosphere will become a very important key element that influences photochemical catalysis oxidative degradation ability.
As the scheme that CN102260003A showed, its numerous micro porous aeration head disperseds that are placed in reactor inner chamber bottom are in the bottom, and by its alleged water distribution board, make the effect of this micro porous aeration head dispersed arrangement become more very, certainly, this is for the situation of using relatively easy settled oarse-grained micron-sized photocatalyst, really there is its favourable one side, but, from another side, the mode that this micro porous aeration head dispersed is arranged, the supply of oxygen atmosphere too disperses, and in fact need most enhanced oxygen blowing the zone be the effective area of photochemical catalysis oxidation, because the Effective depth penetration of short wave ultraviolet in liquid water body has only about 20 centimetres, therefore, needing most enhanced oxygen blowing in fact is exactly zone within peripheral about 20 cm distance of silica tube with the effective area that promotes photochemical catalysis oxidation process, in other words, zone within about 20 cm distance of silica tube periphery is really to need enriched with oxygen atmosphere to supply with the zone that ensures, this regional oxygen atmosphere is supplied with strong more, and oxidizing reaction is also just carried out soon more; Especially especially, produce electrodeless ultraviolet emission in the microwave excitation mode, its characteristics can be accomplished high-power, high strength exactly, this is the strong point of this lamp type of electrodeless ultraviolet lamp, yet, just because of the superpower of its uv-radiation, high strength just more need mate with powerful oxygen atmosphere supply capacity, otherwise, that powerful uv-radiation ability is that major part has been wasted really just.Above address, as the scheme that CN102260003A showed, many effects limit its reactor size, limited its actual treatment capacity, just as clearly illustrating that in its specific embodiment, that can only be that one single jar single treatment amount has only the little reactor about 40 liters, at so little reactor, under the situation of little inner chamber, because size itself is just very little, so, its shortcoming aspect photochemical catalysis oxidation effective area oxygen supply concentration degree just can not be so obvious, even can ignore, more even fully can regard a non-existent at all problem as, in the face of such undersized little reactor,, not may float mind about the shortcoming problem of oxygen supply concentration degree aspect; But, imagine, if can overcome described many limiting factors, if can there be one of way actual implementation large-scale, the reactor of high throughput, effective area oxygen supply reinforcement problem will show especially out within so above-mentioned silica tube periphery 20 cm distance, especially for the situation of using electrodeless ultraviolet lamp as UV source, effective area oxygen supply reinforcement problem is not allowed to despise more within above-mentioned silica tube periphery 20 cm distance, therefore, how among the structure of possible large-scale electrodeless ultraviolet light catalysis oxidative degradation device, strengthen the oxygen supply concentration degree of described effective area, improve the usefulness of waste water degraded equipment, the problem that individual exactly needs are kept a close watch on, this is five of a problem.
Six of problem:
This CN102260003A scheme pumps air within the silica tube that includes electrodeless ultraviolet lamp, reach the aeration-cooling of electrodeless ultraviolet lamp, cooling purpose, and those flow through the air of silica tube, because of being subjected to ultraviolet irradiation, some air can change ozone into, therefore, effusive air is exactly the air that contains some ozone certainly from silica tube, this scheme contains ozone-air with this and is transferred to and is positioned at reactor below micro porous aeration head, and disengage from micro porous aeration head, contain in the ozone bubbles ascension process from bottom to top at these, wherein contained ozone can meet with and take place redox reaction with the organic molecule that runs among the distance, this redox reaction can consume a part of ozone certainly, this does not have query, but, above address, as the scheme that CN102260003A showed, the many effects limit that can't ignore that certainly exist its reactor size, limited its actual treatment capacity, just as clearly illustrating that in its specific embodiment, that can only be that one single jar single treatment amount has only the little reactor about 40 liters, at so little reactor, under the situation of little inner chamber, because overall dimension itself is just very little, so, the longitudinal size of its reactor inner chamber or regard that to contain the liquid degree of depth also can only be a very little size as with reckoning in every item, this size is as clearly illustrating that among its embodiment, have only about 40 centimetres, the Sheng that the reckons in every item liquid degree of depth also just has only 40 centimetres, in fact contain the liquid degree of depth and be less than this number certainly, just analyze with 40 centimetres the Sheng liquid degree of depth, so, is this Sheng liquid degree of depth of 40 centimetres what notion? that is to say, contain the ozone-air ascension and have only short 40 centimetres by the path of waste water, this path is too short, containing the ozone-air bubble passes through at a gallop and only has only 40 centimetres of dark water bodys, too short duration of contact with water body, contained ozone in the bubble, can only there be a very little part to be used to the oxidative degradation organism, and most ozone is in fact just passed by liquid simply, from the liquid level effusion and through the exhaust port emptying, briefly, the oxygenizement potentiality major part of these ozone has been wasted, and, effusion, in fact the ozone that is wasted can cause unnecessary atmospheric pollution; The main contriver of this case once squeezed in one meter dark tank via micro porous aeration head with the normal domestic use ozone machine and contained ozone-air, reach in the depth of water degree of depth under one meter the situation, still can near the water surface, obviously smell the smell of ozone, as seen, the sort of 40 centimetres of dark Sheng liquid degree of depth obviously are to be not enough to utilize fully ozone; As seen, for the such equipment of electrodeless ultraviolet light chemical catalysis waste water DeR device, ozone utilizes incomplete problem also to need to pay close attention to, obviously, what people more expected is that the ozone utilization is more complete, contaminative exhaust emissions no extreme ultraviolet waste water DeR device still less, and this is six of a problem.
Seven of problem:
Its running of waste water catalytic degradation reaction device requires the expenditure of energy, and therefore, operator are bound to wish, when the waste water DeR proceeds to terminal point, can impartially, immediately not stop too early continuing to inject energy to inside reactor only lately; If it is too early to stop to inject the moment of energy, then the waste water degraded not exclusively; And if reach reaction end already, but still inject energy to inside reactor unceasingly, that undoubtedly is at the valuable energy of waste.Its structure of CN102260003A scheme as this case technical background can not provide any instant information constantly to waste water DeR terminal point, so, just can only estimate the terminal point of waste water DeR by experience; And estimate the terminal point of waste water DeR by experience, that obviously can not be satisfactory; So, how make neither in advance also undelayed instant information output constantly, and immediately close energy input reactor in the just right moment at waste water DeR terminal point, the technical threshold that can not despise exactly, this is seven of a problem.
Eight of problem:
Accept the described trade effluent of microwave and photo catalysis degradation treatment, the material that wherein is mingled with some metal particles that originate from mechanical system abrasion process and carbon granules and so on unavoidably, even if quantity is small, its existence almost is difficult to avoid, the disclosure number is installed in the microwave and photo catalysis reaction zone for the described organic membrane separation assemblies in the Chinese patent application case of CN102260003A, being used between silica tube and the membrane separation assemblies that be installed in wherein intercepts ultraviolet dividing plate and do not stop microwave certainly, so, the practical function zone of microwave must cover zone that organic membrane separation assemblies is installed described in this scheme, working mechanism based on membrane separation assemblies, its accumulation process on the organic top layer of membrane separation assemblies of the particulate of aforesaid metal particle and carbon granules and so on is difficult to avoid, and the particulate of this type of described metal particle and carbon granules and so on, the good absorption medium of microwave energy exactly, absorbed the particulate of the described metal particle of accumulation attitude of microwave energy and carbon granules and so on, nature can to the top layer of its organic membrane separation assemblies of being close to produce based on heat penetration erosion mechanism continue pierce destruction, as mentioned above, since the structures shape of this its device of CN102260003A application case can only select the polyvinylidene fluoride film material for use, about 140 degrees centigrade of this polyvinylidene fluoride film material heatproof, high really more many than general film material heatproof, yet, absorbed the heatproof temperature limit that its point-like of particulate of the described metal particle of accumulation attitude of microwave energy and carbon granules and so on is pierced very easy this polyvinylidene fluoride film material of breakthrough of heat penetration erosion effect of formula, for above-mentioned reasons, well imagine, pvdf membrane material in its device of this CN102260003A application case will be significantly less than the ideal work-ing life of being expected its actual service life, the structure of this its device of CN102260003A application case, determined that under this structural framing the heat penetration erosion destruction problem that above-mentioned point-like is pierced formula can't be avoided; Therefore, how to get around the heat penetration erosion destruction problem that this point-like is pierced formula, also need consider, this is eight of a problem.
Nine of problem:
The disclosure number is the Chinese patent application case of CN102260003A, open the 0008th section literal of text text of its specification sheets and claim the second, for its device catalyst particle size scope that can be suitable for, a qualification is arranged, this particle size range is defined as 20 nanometers to 100 micron.We know, under some pH value was regulated not in place, the inappropriate situation of pH value in advance, titanium dioxide fine particles was reunited easily, and then influences its effective working interface area, influences its photochemical catalysis usefulness; Especially among this particle size range those relatively than the section of small particle size,, the pH value incorrect agglomeration traits that cause not in place because of pH value preset appears especially easily; For the situation that this catalyst particles is reunited, be immediately to adopt an effective measure, carry out depolymerization running at coacervate; Yet we do not see that any helping immediately dissolve the structure of this problem or can immediately dissolve the scheme prompting of this problem among this CN102260003A scheme.For can only being the reactor of small scale structures just like that because of many effects limit as the CN102260003A scheme, still can manually directly mention reactor, topple over and inspect in the reactor outside, handle above-mentioned reunion situation, so, if might expand its capacity, just so to say, if be that several cubes are to large-scale reactor of dozens of cubical or huge reactor, that obviously be not manual topple over its operation the problem that can tackle, so, for the situation that this catalyst particles is reunited mutually, how to realize instant original position disposal, be exactly a technical problem, this is nine of a problem.
Ten of problem:
In the disclosure number is in the expressed apparatus structure of the Chinese patent application case of CN102260003A, be used to shield the silica tube that protects electrodeless ultraviolet lamp, its outer wall, refer to the outer wall of silica tube, through for a long time with the contacting of processed trade effluent, incrustation gradually unavoidably, the long-pending material of dirt mainly are difficult by mineral-type impurity that light-catalyzed reaction touched certainly, incrustation phenomenon because of this mechanism forms is easy to be observed after the equipment long-play; Be attached to the dirty lamination of described silica tube outer wall, though be very thin one deck, also be enough to ultraviolet radiation to electrodeless ultraviolet lamp and cause significantly and stop, this will cause the actual treatment of this microwave and photo catalysis reaction treating device to be renderd a service significantly reducing; The bubble of dispersed ascension is because of too disperseing in its reactor, wash away strength a little less than, keep the bright and clean of silica tube surface if only rely on this comparison dispersive bubble, really undertake to do what is apparently beyond one's ability, in other words, this is dispersive bubble relatively, and it is more weak washes away the incrustation process that strength still is not enough to stop fully this silica tube surface; In the use of laboratory yardstick, above-mentioned incrustation problem is subtle, and still, on the industrial application yardstick, this incrustation problem undoubtedly will highlight; Therefore, how under the prerequisite of not tearing machine open, remove the dirty lamination on this silica tube outer wall immediately, effectively, keep the high-level efficiency that continues of this microwave and photo catalysis treatment unit, this problem is also very important, and this is ten of a problem.

Based on the structure of this case, the DESIGN OF REACTOR volume is that single jar of wastewater treatment capacity can be expanded to several cubes to dozens of cube; Even single jar hundreds of cubical volumes, also allow; Based on this structure of this case, can reduce the frequency of a complete set, substantial length of operation significantly, help the saving of human and material resources.
This case reactor is among its operation, described its high-density ascension bubble flow that is discharged of cluster shape micro porous aeration head cluster, in the ascension that makes progress, and wrapped folder, carry, guided liquid-flow, form a kind of motion that is similar to the fountain form, in this kind motion, the high-density bubble flow wrapped folder that is derived from described cluster shape micro porous aeration head cluster liquid to the silica tube region gush and on, and then relatively the concentrated area is impacted, the effective area of the described photochemical catalysis oxidizing reaction by the silica tube periphery, be subjected to described high-density bubble flow wrapped folder, the liquid stream that carries is impacting, after the described effective area by the silica tube periphery, by the liquid layer of top area to around diffusion, sink via the neighboring area, arrive reactor intracavity bottom zone, again through the wrapped folder of described its high-density ascension bubble flow that is discharged of cluster shape micro porous aeration head cluster, carry, continue the motion that it is similar to the fountain form, so circulation endlessly; The liquid circulation campaign of this relative big scale that is guided helps to guarantee the homogenizing of inside reactor liquid degradation reaction process, and this is necessary for large-scale electrodeless ultraviolet light catalysis DeR device.
Its UV source of this case reactor is to rely on microwave excited electrodeless ultraviolet lamp, the uv-radiation characteristics of this lamp type can be accomplished high-power, high strength exactly, yet the Effective depth penetration of ultraviolet ray in liquid water body has only about 20 centimetres, therefore, zone within about 20 cm distance of silica tube periphery is the effective area, and this zone is exactly the efficient zone of photochemical catalysis oxidative degradation; This case method is to be positioned at the described cluster shape micro porous aeration head cluster under the silica tube, come the concentrated area to discharge highdensity ascension bubble flow, it is discharged towards silica tube periphery photochemical catalysis oxidation effective area as concentrated area as the fountain, the oxygen atmosphere that this method helps to improve the described effective area of silica tube periphery is supplied with intensity, helps accelerating ultraviolet catalyzing oxidizing degrading reaction process.
Based on this case structure, the capacity of reactor or treatment capacity can significantly be expanded, described significantly expansion, be that the design volume of irradiation zone realizes a little less than microwave zero irradiation zone or the microwave by significantly expanding, so, the lateral dimension of reactor, longitudinal size all is significantly to expand certainly, therefore, inside reactor is contained the liquid degree of depth and can be deepened significantly similarly, for example, can deepen to one meter, two meters, three meters, four meters, five meters, six meters, even ten meters, or the like, containing under the enough dark situation of the liquid degree of depth, contain ozone-air bubble ascension path sufficiently long, contain the time sufficiently long that the ozone-air bubble contacts with water body, in its ascension process just can with abundant reducing substances fortune, and thoroughly or be close to and exhaust ozone contained in the bubble up hill and dale, thus, contain that ozone composition oxidation potential utilizes incomplete problem to be solved in the ozone-air bubble, and,, just can not be entrained with the ozone that can cause environmental pollution again in the reactor tail gas because long ascension path causes ozone to exhaust.
This case is with external multistage filter, reach interception step by step from the collision fragment of the small scale of coacervate macrobead to ten number nanometers to catalyst particles, be close to recovery, reuse photocatalyst up hill and dale, be close to the secondary pollution of taking precautions against catalyst loss up hill and dale and causing; This is tackled scheme step by step and can protect secondary filter to make its filtration passage avoid the rigid obstruction of large particulate matter; Wherein the pre-filtering aperture of the first step is between 5 microns and 300 microns, and its aperture of partial micro-filtration is between 25 nanometers and 1000 nanometers, and its aperture of the ultrafiltration of the third stage is between 15 nanometers and 2 nanometers; Such interception scheme can fully be tackled nano level photocatalyst, and it can be close to certainly and tackle this median size of gas phase titanium dioxide P25 up hill and dale is the catalyzer of 21 nanometers; Preamble is addressed, the gas phase titanium deoxide catalyst of nano level P25 and so on, it is the commercially available catalyzer that to buy in a large number, also be weather resistance, stability, the known good photocatalyst of UV-light wave band photocatalysis performance, certainly, it also is in fact to pay the utmost attention to the photocatalyst of selecting for use in the industrial scale applications; This case catalyzer interception scheme is complementary with the virtual rating of catalyzer market supply, actual kind, merges mutually.
And, because this case catalyzer interception mechanism is external mechanism, its filter core just needn't be soaked in the liquid of the strong oxidation of inside reactor, strong uv irradiation, therefore, can needn't consider tolerance fully, like this, just not have restriction aspect the extraordinary tolerance selecting for use of filter core material to uv irradiation, strong oxidizing condition, can on more vast optional material kind, select, and need not be confined to the material of the PVDF and so on of comparison costliness fully again.
Related strainer at different levels all has commercially available, commercially available strainers at different levels, the discharge outlet of draining-off sewage when its sewage draining exit is exactly back flushing, this class back flush type equipment is used in this case, be to be used for tackling step by step catalyst particles, originally the sewage draining exit of commercially available relevant device, the recovery that is used as being held back catalyst particles in this case by migrating are again with delivery port or reflux and use delivery port again.
Above address, based on this case structure, the capacity of reactor or treatment capacity can significantly be expanded, described significantly expansion, be that the design volume of irradiation zone realizes a little less than microwave zero irradiation zone or the microwave by significantly expanding, so, from in appearance, the lateral dimension of reactor, longitudinal size all is significantly to expand certainly, therefore, inside reactor is contained the liquid degree of depth and can be deepened significantly similarly, for example, can deepen to one meter, two meters, three meters, four meters, five meters, six meters, even ten meters, or the like, containing under the enough dark situation of the liquid degree of depth, contain ozone-air bubble ascension path sufficiently long, contain the time sufficiently long that the ozone-air bubble contacts with water body, in its ascension process just can with abundant reducing substances fortune, and thoroughly or be close to and exhaust ozone contained in the bubble up hill and dale, thus, contain that ozone composition oxidation potential utilizes incomplete problem to be solved in the ozone-air bubble, and,, just can not be entrained with the ozone that can cause environmental pollution again in the reactor tail gas because long ascension path causes ozone to exhaust; Only ought be subject to processing that reducing substances is in organic pollutant is degraded totally in the water body, not had in the water body can be for the organic pollutant of ozone oxidation reaction again, and those redundant ozone just might no longer consume and see through long ascension path effusion liquid level; The front is spoken of, among some problems that this case solves simultaneously one, it is the circulation of the relative big scale of enhanced reactor internal liquid, this systemic circulation mechanism of having strengthened has been facilitated the uniformity of inside reactor liquid its contained organic pollutant degradation reaction process, thus, at several cubes that this case structure is allowed to the processing capacity framework of dozens of cube even hundreds of cube volume, above the inside reactor liquid level, have in the ozone effusion, the DeR that promptly shows inside reactor has reached terminal point, and be the terminal point that the whole uniformity of internal liquid ground reaches DeR, this terminal point determining factor is that the condition that can provide with this case organization plan is complementary; This case is at its exhaust port position installing ozone sensor of reactor, detect ozone in this locations of structures, just mean that the inside reactor DeR reaches home, ozone sensor and connect with the composite structure of ozone content indicating meter with ozone attention device or ozone content indicating meter or ozone attention device, be used for providing indication information accurately to operator, this case and the electric signal that ozone sensor is exported send power-supply controller of electric to by cable, this power-supply controller of electric also connects with magnetron and pneumatic pump respectively by cable, power-supply controller of electric carries out the power switch action according to its received described electric signal, certainly, its function mode is, receive in the signal that ozone that ozone sensor sends overflows at power-supply controller of electric, close the power supply that leads to magnetron and pneumatic pump automatically; This case is organization plan according to this, can in time know the terminal point of inside reactor DeR process; And organization plan according to this, when reaction reaches terminal point, close the power supply of magnetron and pneumatic pump automatically, in time stop to inject energy to inside reactor, so can avoid unnecessary energy dissipation; And, this case is structure according to this, in DeR reaches home, can in time close the power supply of described magnetron and pneumatic pump, this power-off action has also stopped the generation process of ozone synchronously, together in a flash, because ozone generation process is in time stopped, just do not have and disengage, thereby avoided unnecessary secondary pollution or said secondary pollution from described exhaust port above a large amount of ozone that need; Its framework of this case has determined it not have ozone more than needed can supply discharging.
Among this case structure, the microwave exposure spatial domain of its inside reactor is subjected to forcing to cut off, limit, this case and adopt the multistage backwash filter structure of external cascade to tackle catalyst particles subtly, back flush type hollow fiber microfiltration membrane assembly wherein and back flush type polysulfone hollow fiber ultrafiltration membrane system are all external and away from reactor core, microwave can not shine described membrane module fully, based on this structure of this case, got around described point-like fully and pierced the heat penetration erosion destruction problem of formula, this problem is settled properly thus.
Be installed in the ultrasonic transducer of reactor bottom in this case structure, can start at once where necessary; Above address, under some pH value was regulated not in place, the inappropriate situation of pH value in advance, titanium dioxide fine particles was reunited easily, and then influences its effective working interface area, influences its photochemical catalysis usefulness; Especially among this particle size range those relatively than the section of small particle size,, the pH value incorrect agglomeration traits that cause not in place because of pH value preset appears especially easily; For the situation that this catalyst particles is reunited, be immediately to adopt an effective measure, carry out depolymerization running at coacervate; Take place under the serious situation of reuniting at catalyst particles, the ultrasonic transducer that is positioned at reactor bottom in this case structure is OnNow easily, immediately implement the depolymerization running, realized thus disposing at the instant original position of this catalyst particles agglomeration traits.
Be used to shield the silica tube that protects electrodeless ultraviolet lamp in the structure, its outer wall, refer to the outer wall of silica tube, through for a long time with the contacting of processed trade effluent, incrustation gradually unavoidably, the long-pending material of dirt mainly is to be difficult for by the mineral-type impurity that light-catalyzed reaction touched certainly, and the incrustation phenomenon because of this mechanism forms is easy to be observed after the equipment long-play; Be attached to the dirty lamination of described silica tube outer wall, though be very thin one deck, also be enough to ultraviolet radiation to electrodeless ultraviolet lamp and cause significantly and stop, this will cause the actual treatment of this microwave and photo catalysis reaction treating device to be renderd a service significantly reducing; Be positioned at the ultrasonic transducer of reactor bottom in this case structure, among the depolymerization running that the irregular situation of seriously reuniting at accidental catalyst particles is carried out, its radiating ultrasonic wave, certainly also can arrive silica tube place locations of structures, this ultrasonic wave is also being carried out the ultrasonic clean scale removal work at the long-pending thing of silica tube surface dirt in the lump when carrying out original position depolymerization running; And, the installation position of ultrasonic transducer is away from silica tube place locations of structures, decay to some extent when ultrasonic radiation arrives the silica tube position, therefore, the suffered ultrasonic impact in silica tube surface is low intensive ultrasonic impact, this low intensive ultrasonic impact scale removal leniently, can avoid again or significantly weaken ultrasonic cavitation its silica tube surface smoothness loss that may cause; Based on this structure of this case, can under the prerequisite of not tearing machine open, remove the dirty lamination on this silica tube outer wall immediately, effectively, safeguard the high-level efficiency that continues of this microwave and photo catalysis DeR device by this.
In brief, this case structure utilizes metal cage to retrain microwave more closely, has reached the target that allows the reactor design capacity significantly to expand; Simultaneously, this case structure has also been strengthened the cyclic motion of the relative big scale of inside reactor liquid; This case structure and to be set up in described its highdensity bubble flow that is discharged of cluster shape micro porous aeration head cluster under the silica tube realizes the significantly lifting at the oxygen supply concentration degree of emphasis reaction zone; This case structure and reached at the nm-class catalyst particulate from the collision fragment of its coacervate macrobead to ten number nanometers widely, meticulous interception; Its related filter core Material Selection face also thereby enlarged; Based on this case structure, its DeR endpoint information can in time be known; Can close energy input in its DeR terminal point automatically to reactor; In its DeR terminal point, also automatically in time stop the generation process of ozone, avoided unnecessary secondary pollution; Its structure and immediately original position dispose the accidental catalyst particles situation of seriously reuniting, also incidentally clean described silica tube surface simultaneously, keep its good UV-light transparent performance with ultrasonic wave through the low intensive gentleness after the reduction of teletransmission appropriateness.
This case structure of reactor has solved described serial problem totally.
