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, as an example, can be the Chinese patent application case of CN102260003A referring to publication number.

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 for preventing that ultraviolet ray is to the radiation injury of 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 the work that its research staff launches in this field is admirable.

Based on the meaning of sincere admiration, and, common striving direction, what will talk below us is problem.

Below the problem that will speak of has seven; These seven problems are seven 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 for interception catalyzer titanium dioxide fine particles is to be placed in the reactor inner chamber, be immersed in and handle among the 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, the recycling purpose, 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 apparent 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 concept 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 exports.

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 namely 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 etc. 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; The at present known commercially available photocatalysts that are used for the UV-light wave band that can actually use in a large number that can make a big purchase in large quantities 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 in market to obtain, 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 more high, 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 etc. 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 for the membrane module of interception photocatalyst, be to wash away the stripping film assembly surface adsorbed with the ascension bubble, the catalyst particles of deposition, 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 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 expect, in other words, microwave energy from magnetron is not used to excite electrodeless ultraviolet lamp fully, and have quite a few only to be used for exciting 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 about this apparatus structure integral body in this its embodiment of CN102260003A application case, 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 corresponding 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, namely 0.04 cube, in other words, it is once a complete set of, substantial length of operation has only solved 0.04 cube 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, its preferred structure size of this case is single jar of 0.04 cube of such wastewater treatment capacity of correspondence roughly, 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 its actual waste water degradation treatment efficient of scheme of being showed by CN102260003A may not be fully up to expectations.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 by the repetitive operation number of times of head to tail of this intermittent type wastewater treatment equipment, improve its waste water treatment efficiency, be a significant technical problem that merits attention, this is three of problem.

Four of problem:

The scheme that this kind showed by CN102260003A, 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 for the treatment of 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 an individual problem certainly, and this is four of 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 etc. of photocatalyst, it three is that oxidized object is organic concentration in the water body, oxidation complexity that the organic molecule structure determines himself etc., 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.

The scheme of showing as CN102260003A, 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 the oarse-grained micron-sized photocatalyst that uses relatively easy sedimentation, 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 more strong, and oxidizing reaction is also just carried out more soon; 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, the scheme of showing as CN102260003A, 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 problem at all as, in the face of such undersized little reactor, about the shortcoming problem of oxygen supply concentration degree aspect, not may float mind; 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 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 being subjected to ultraviolet irradiation, some air can change ozone into, therefore, the air that flows out from silica tube is exactly the air that contains some ozone certainly, 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, the scheme of showing as CN102260003A, 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 concept? 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 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 also undelayed instant information output in advance constantly at waste water DeR terminal point, and immediately close energy input to reactor in the just right moment, the technical threshold that can not despise exactly, this is seven of problem.

Advantage of the present invention is, microwave constrainer with the cage shape of metal material, electrodeless ultraviolet lamp is wrapped among its inner chamber, and with its inner chamber of microwave constrainer of this cage shape and the waveguide UNICOM that is derived from magnetron, its whole locations of structures of the microwave constrainer of this cage shape also is the inside at described silica tube, this silica tube is isolated for the gas-liquid thing, the performance screen protects the member of effect, this silica tube is positioned at the inside of reactor, by this step, the microwave that comes via the waveguide transmission is constrained within its effective workspace, contained the unhelpful dissipation of microwave to peripheral waste water water body, and a little less than making up microwave between microwave constrainer outer wall and the reactor wall irradiation spatial domain or microwave zero irradiation spatial domain; The step of this case method also comprises: the size in irradiation spatial domain or microwave zero irradiation spatial domain a little less than three-dimensional extension, the described microwave of expansion inside reactor, by this step, can significantly expand the DESIGN OF REACTOR volume, allow single jar of wastewater treatment capacity of reactor significantly to promote, and need not worry again that microwave energy dissipates too much in unhelpful waste water water body temperature-rise effect.

Adopting under the situation of bright finished Stainless Steel Wire cylinder mould as the microwave constrainer, and, make under the situation of microwave constrainer through mold pressing, welding or splicing process at employing punching stainless steel plate, specular reflection mechanism via complexity, can to greatest extent the UV-light from electrodeless ultraviolet lamp be transferred out, and remedy himself entity of described metal cage to greatest extent light is blocked, absorbs the loss that causes.

Rely on this case method, the design volume of this waste water DeR device is that single jar of wastewater treatment capacity can be expanded to several cubes to dozens of cube; Based on this method of this case, can reduce the frequency of a complete set, omnidistance waste water degraded operation significantly, be conducive to the saving of human and material resources.

On the other hand, this case method is made the cyclic motion of relative big scale with described circulation conductor guided liquid-flow, ascension contains the ozone gas burble and can pull, guide the liquid stream of inside reactor along the internal passages fast rise of this circulation conductor in the reactor, and after impacting, pass through silica tube periphery photocatalytic degradation conversion zone, by top area to around the diffusion, sink via the neighboring area, arrive reactor intracavity bottom zone, converge to the internal passages of circulation conductor again through the hydraucone of circulation conductor, continue its circulation; 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 DeR device.

Its UV source of this case method 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 only had an appointment 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 with described circulation conductor, pack is from the bubble flow of numerous micro porous aeration heads, its concentrated area is discharged towards silica tube periphery photochemical catalysis oxidation effective area, 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 method, 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, etc., containing the liquid degree of depth enough under the dark situation, 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, because long ascension path causes ozone to exhaust, just can not be entrained with the ozone that can cause environmental pollution again in the reactor tail gas.

This case method is with external multistage filter, reach the 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 hold-up interception method and can protect secondary filter to make its filtration passage avoid the rigid obstruction of large particulate matter step by step; 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 hold-up interception method 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 hold-up interception method is complementary with the virtual rating of catalyzer market supply, actual kind, merges mutually.
