The plasma purification module that poison purifies.
Background technology
Along with the raising of people's living standard, people increasingly pay attention to the environmental quality of indoor.Air in the market
The technology that depurator uses substantially has following a few class: strainer filtering absorption, catalyst are decomposed, ultra violet lamp and plasma
Body etc..
Strainer filtering absorption is to utilize the filtration of material dust antibacterial of fine pore, employing activated carbon adsorption formaldehyde, VOC etc. to have
Pest matter, but this mode does not fundamentally solve pollution problem, needs often to change filter material, and also initiation two
The risk of secondary pollution；Catalyst decompose can only decomposing organic matter, purification efficiency is the highest to be needed to combine other technology and uses；Purple
Outer light irradiation can only kill antibacterial；
Plasma not only can dust cleaning and sterilizing, can also decomposition gas pollutant but also no material consumption, thus enjoy the green grass or young crops of people
Look at.Plasma air disinfection purifier is to utilize corona discharge generation plasma to purify air, and its cleaning principle is profit
Formed with living radical, high energy electron and the particle produced in the highfield of plasma and plasma and plasma
During the ultraviolet that produces, effective destroy in various viruses, antibacterial nucleic acid, protein so that it is can not carry out normal
Metabolism and biosynthesis, thus it is dead to cause it；Dust in gas is because bringing in heating region and charged particle collision
Electric charge, is collected on pole plate under the effect of electric field；Volatile Organic substance is ionized, is dissociated into little molecule, with oxidation
Property radical reaction generate CO2And H2O。
The core of plasma air disinfection purifier is plasma producing apparatus, and current plasma fills
Put that the wired cartridge type of electrode form of employing, syringe-type, line be board-like and needle plate type.Patent CN1785485A describes a kind of plasma
Body discharge catalytic air purifier, produce plasma corona discharge electrode be zigzag, star, prickle wire, fishbone line, line electrode,
Needle electrode, another electrode is the electrode being loaded with semiconductor light-catalyst, electrode can be template electrode, cylindrical electrode combination,
Net electrode, pipe electrode etc.；Catalyst is supported on stainless (steel) wire electrode by AB glue.There is following deficiency in technique scheme:
1, corona discharge electrode uses line electrode or needle electrode, when the later stage uses cleaning, is easily caused electrode deformation, after impact
The use of phase discharge cell；
2, when corona discharge electrode uses zigzag, star, prickle wire, fishbone line, the region of discharge formed during each point discharge
Little, cause purification efficiency low；
3, catalyst is supported on stainless (steel) wire electrode by AB glue, and catalyst is chronically in plasma, can with etc.
The composition reaction of strong oxidizing property in gas ions, catalyst can fall off, additionally, the mode of this supported catalyst is difficult to ensure
The flatness of net electrode plane, causes the electric discharge of whole region of discharge uneven, and ozone amount increases；
4, more weak due to corona discharge strength ratio, when catalyst is supported on another electrode, the distance of distance catalyst compares
Far, the catalysis efficiency of catalyst reduces.
Utility model content
The purpose of this utility model is to provide the low temperature plasma air that a kind of corona discharge electrode is more firm, purification efficiency is high
Sterilizing and purifying module.
The purpose of this utility model can be achieved through the following technical solutions:
Low temperature plasma air sterilization cleaning module, this cleaning module includes taper corona discharge electrode and circular hole slab electrode；Institute
The taper corona discharge electrode rectangular array stated is distributed in the upper and lower both sides of wire netting, and the taper corona discharge electrode interval of wire netting both sides is arranged；
It is loaded with photocatalyst on described wire netting；
All offering the circular hole of rectangular array distribution on two described circular hole slab electrodes, wire netting is positioned at two circular holes
Between plate electrode；
Taper corona discharge electrode described in wire netting both sides and the circular hole coaxial of this mother rib lateral rotundum plate electrode.
Described photocatalyst is on corona discharge electrode.
Described cleaning module contains two region of discharges, and the electric discharge junior unit of two region of discharges uses spaced
Mode.
The beneficial effects of the utility model: this utility model corona discharge electrode uses tapered electrode, and another electrode is borehole structure,
Two electrodes use coaxial structure, and the compare corona discharge electrode of other structure of tapered electrode is more firm, and the later stage will not deform when cleaning；
Using the taper discharge mode to circular hole, region of discharge is umbrella, increases the region of discharge of each little discharge cell, improves clean
Change the purification efficiency of unit；Before wire netting impregnated catalyst, using plasma processes, and improves catalyst and wire netting
Adhesion, catalyst from heating region closer to, improve the catalysis efficiency of catalyst, and this mode of loading does not interferes with
Corona discharge.
