Description
Technical field
The utility model belongs to low temperature plasma application field, is specifically related to a kind of plasma body water purifier that is provided with fiber filter curtain.
Background technology
Micro-fibre fabric etc. have the material of high porosity and high surface area, and pollutent is had to very strong adsorptive power, are widely used in water filtering system as filter material always.Yet, adopting at present in the water filtering system of primitive fiber as filter material, filter material all, without effective self cleaning method, need to regularly replace new fibre filtering material.Regular maintenance, not only increases material cost, also increases the maintenance cost of filtering system, and, user is used and brought inconvenience.Once safeguard not in time, not only can not purify water, also may cause the secondary pollution at water source, security is without guarantee.Therefore, fibre filtering material is necessary to increase instant self-cleaning function, do not allow pollutent prolonged stay on filter material surface, guarantee that on the one hand filtering system can constantly keep degree of cleaning and the strong adsorptive power on fibre filtering material surface in life-time service, security is secure; Save on the other hand the expense of a large amount of maintenance costs and replacing fibre filtering material, improved its usage economy of filtering system.
Yet fiber itself is passive filter material, itself do not possess the ability of decomposition or cleaning surface contaminant, only collect and do not process, need consideration and the combination of other active purification systems could realize the instant self-cleaning function of system.
In recent years, lower temperature plasma technology is as a kind of emerging Pollutant Treatment technology, there is the features such as flow process is short, efficiency is high, applied widely, be widely used in the synthetic and activated water field of industrial gaseous waste processing, dedusting, vehicle exhaust processing, wastewater treatment, ozone.Lower temperature plasma technology is mainly based on atmospheric pressure plasma discharge technology, utilize deep oxidation and the decomposition reaction of source of pollution in ozone, Sauerstoffatom, the free group of hydroxyl isoreactivity and atmosphere or the water that atmosphere pressure discharging produces, reach the object that removes objectionable impurities in atmosphere or water, follow ultraviolet photolysis, shock wave simultaneously, thereby remove organism, killing pathogenic bacteria in atmosphere or water.Utilize various living radicals and ultraviolet strong oxidation and sterilizing effect in plasma body, degraded organic contamination source, sedimentation metal ion, killing pathogenic bacteria, source of pollution to life and industrial discharge all have general applicability, volume compact, invest low, be not subject to environmental restraint, be subject to extensive approval.
Yet, current disclosed plasma body water treatment device and method all exist efficiency on the low side, the problems such as unit consumption of energy height, single decontamination effect improving is far below expection, and reason is that the current plasma device for the treatment of sewage is all based on dielectric barrier discharge, corona discharge, spark discharge or thermal equilibrium plasma.On the one hand because air pressure is high, electric discharge can only be in local zonule activated plasma, and, collision frequency is high, free path is short, in plasma body, living radical diffustivity is poor, the life-span is short, is not easy to source of pollution contact reacts in abundant and water, therefore, the utilization ratio of living radical is not high, causes processing efficiency low; Current pass through discharge gap fast on the other hand; pollutent and plasma body are too of short duration duration of contact; or having part pollutent to have no chance contacts with plasma body; by plasma decomposes, just do not left region of discharge, therefore, single decontamination effect improving is not good; needing long-time iterative cycles to process just can accomplish the end in view; processing efficiency is low, and not only energy consumption is high, is also applicable to large-scale promotion.The simple strength of discharge that increases there is no unusual effect to improving single decontamination effect improving, can further increase energy consumption on the contrary.How to make the pollutent long period be trapped in region of discharge and fully contact with plasma body, be only the effective way that improves single decontamination effect improving.
Primitive fiber has strong adsorptive power to pollutent, plasma body has strong capacity of decomposition, the two is in conjunction with having complementarity: the preferential absorb polluted matter of primitive fiber, make pollutent can not leave fast region of discharge with current or air-flow, make pollutent and plasma body have abundant touch opportunity and resolving time, significantly improve single decontamination effect improving; The strong capacity of decomposition energy settle accounts immediately of plasma body is adsorbed in the pollutent of fiber surface, makes fiber surface all contamination-free accumulations in prolonged application, keeps surperficial degree of cleaning and strong adsorptive power constantly.
Summary of the invention
The purpose of this utility model is by fiber filter curtain is set in the discharge gap between discharge electrode, water water conservancy diversion is become to cascade, greatly increase the interface that water contacts with plasma body, extend current through the time of plasma slab simultaneously, and source of pollution are preferentially adsorbed on fiber filter curtain, can the long period be trapped in plasma slab, by plasma body, fully be decomposed, thereby reach the object that greatly improves purification efficiency and single decontamination effect improving.
