Description
Technical field
The present invention relates to a kind of membrane separation assemblies and avoid the waste water microwave and photo catalysis degradation treatment device of heat etching damage, belong to the C02F technical field of waste water processing.
Background technology
Microwave and photo catalysis degradation treatment technology, effectively to the innoxious process for treating that contains the organic pollutant trade effluent, development in recent years is swift and violent as a kind of.
About the microwave and photo catalysis degradation technique,, can referring to publication number the one Chinese patent application case of CN102260003A as an example.
This publication number is the one Chinese patent application case of CN102260003A; Be with microwave as excitaton source, excite electrodeless uv lamp emitted in ultraviolet line, be mixed with the suspension liquid of photocatalyst titanium oxide in liquid internal irradiation; This electrodeless uv lamp is shrouded by silica tube to be protected; Have pneumatic pump 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, and 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 drum, carries the water of analysing after the purification, and realizes 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 oxide 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 that is directed against organic pollutant certainly.
This publication number is that the one 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.
Accept the said trade effluent of microwave and photo catalysis degradation treatment; Wherein be mingled with the material of 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; This publication number is that the said organic membrane separation assemblies in the one Chinese patent application case of CN102260003A is installed in the microwave and photo catalysis reaction zone; Being used between silica tube and the membrane separation assemblies that be installed in wherein intercepts ultraviolet dividing plate and stopped not microwave certainly, and so, the practical function zone of microwave must cover organic membrane separation assemblies described in this scheme and install regional; 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 said metal particle and carbon granules and so on, the good absorption medium of microwave energy exactly; Absorbed the particulate of said metal particle and carbon granules and so on of the accumulation attitude of microwave energy; 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 stated and 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; Really high more many than general film material heatproof, however the heat penetration erosion effect that its point-like of particulate of said metal particle and carbon granules and so on that has absorbed the accumulation attitude of microwave energy is pierced formula breaks through the heatproof temperature of this polyvinylidene fluoride film material very easily and limits; For above-mentioned reasons; Well imagine that the pvdf membrane material in its device of this CN 102260003A application case will be significantly less than the ideal work-ing life of being expected, the structure of this its device of CN102260003A application case its actual service life; Determined that under this structural framing the heat penetration erosion destruction problem that above-mentioned point-like is pierced formula can't be avoided.
On the other hand, be in the expressed apparatus structure of the one Chinese patent application case of CN102260003A at this publication number, be used to shield the silica tube that protects electrodeless uv lamp; Its outer wall refers to the outer wall of silica tube, through for a long time be processed contacting of 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 said silica tube outer wall, though be very thin one deck, also be enough to ultraviolet radiation to electrodeless uv 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; 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 not shutting down, do not tear open under the prerequisite of machine, removing 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, is another technical problem that merits attention.
