Technical field
The utility model relates to a kind of plasma technique that utilizes, and degraded soot gas molecule, removes the cooking fume control equipment of various pernicious gases, efficient dispelling abnormal flavor and sterilization, relates in particular to a kind of dielectric barrier discharge plasma smoke purifier.
Background technology
The major technique that solves fume purifying at present has mechanical filtering type, rinsing type and electrostatic, though these technology can reduce the environmental pollution that oil smoke causes to a certain extent, but still has more problem.Concrete condition is as follows: one, mechanical filter technology: utilize the cellular structure of filter material, and the dust granules in the fluid-absorbent (gas or liquid), thus reach the purification purpose; The subject matter that exists has: 1. windage is bigger, and 2. purification efficiency is low, 3. can not eliminate the unusual smell.Two, water-washing technique: cleaning equipment is used liquid absorption process removal oil smoke such as moisture film, spraying, impact, and main at present the employing utilized principle of inertia, is aided with the oil droplet in the water spray removal oil smoke; Problem is in actual applications: 1. for lack of water or winter cold the place be difficult to use, 2. be easy to generate the fan belt water phenomenon, the 3. more waste water of Chan Shenging, direct discharging can cause serious secondary pollution problem.Three, electrostatic means: be meant and utilize the electrostatic precipitation principle, make droplet charged and the mist of oil particle efficiently captured; Mainly have following problem in actual applications: 1. pole plate is difficult to clean, 2. effective dispelling abnormal flavor, the soot gas molecule of 3. can not degrading.
Summary of the invention
The purpose of this utility model is exactly the plasma smoke purifier that a kind of soot gas molecule of can degrading, dispelling abnormal flavor, kill bacteria, purification efficiency height, easy care, non-secondary pollution are provided for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions: the plasma smoke purifier, it is characterized in that, comprise casing, equal drift net, screen pack, plasma electric field, plasma electrical source, detachable oil-collecting net, draw-off tray, described casing is provided with oil smoke import, oil smoke outlet, described equal drift net, screen pack, plasma electric field, detachable oil-collecting net are located between this oil smoke import and the oil smoke outlet successively, and described draw-off tray is located at the bottom of casing.
Described plasma electric field comprises positive plate, minus plate, described positive plate and minus plate are oppositely arranged, be provided with the oleophobic property insulation barrier at positive plate and minus plate facing surfaces, at minus plate and the densely covered needle-like prickle of positive plate facing surfaces, described positive plate, minus plate are connected with plasma electrical source respectively.
Described positive plate, minus plate and described equal drift net, screen pack, detachable the oil-collecting net is vertical lays, and constitutes an oil smoke passage between positive plate and the minus plate.
Also comprise connecting rod, described positive plate, minus plate are connected with plasma electrical source by this connecting rod respectively.
Described plasma electrical source adopts high-frequency electric field impulse waveform dutycycle type variable, and its pulse voltage and dutycycle can be according to the power and the purification object variation of clearing machine.
Described plasma electric field constitutes an assembled unit with detachable oil-collecting net, and this assembled unit can have many groups to be sequentially arranged between interior screen pack of casing and the oil smoke outlet.
Also comprise a dividing plate, this dividing plate is horizontally set with in casing and with casing and is divided into upper and lower two parts, and top is provided with described equal drift net, screen pack, plasma electric field, plasma electrical source, detachable oil-collecting net, and the lower part is provided with draw-off tray.
Described dividing plate is funnel-form, and its middle part is provided with oil trickling hole.
Described casing bottom surface is provided with adjutage.
Described bottom of shell is provided with scroll wheel.
The utility model is owing to adopted above technical scheme, promptly be provided with a plasma electric field, this plasma electric field comprises positive plate, negative electrode prickle plate, oleophobic property insulation barrier, connecting rod, plasma power supply and control system composition thereof, and positive plate, negative electrode prickle plate are connected to plasma power supply unit by the positive and negative electrode connecting rod respectively.Plasma power supply unit injects the argon-arc plasma field of being made up of positive plate (collecting plate) and minus plate (discharge electrode) to high-energy, and the positive plate levels has covered the oleophobic property insulation barrier, and the needle-like prickle gathers on the minus plate.Because the radius of curvature of minus plate prickle is very little, near the electric-field intensity it is high especially, makes to form a large amount of thermal nonequilibrium attitude plasmas in the electric field space, has wherein comprised a large amount of high-energy electrons, ion, excited atom and the free radical of strong oxidizing property is arranged.The average energy of these active particles is higher than the most pernicious gases and the bond energy of oil smoke molecule, and the chemical bond generation monoatomic molecules and the solid particle of portion gas are opened in they and soot gas molecule generation frequent impact, generate a large amount of OH, HO simultaneously 2, free radical and the extremely strong O of oxidisability such as O 3, they take place to generate harmless product H behind the chemical reaction with pernicious gas molecule (peculiar smell molecule) 2O and CO 2In addition, the oil smoke that is not decomposed, under the effect of plasma electric field, the bear electricity is collected by positive plate, because the oleophobic effect on barrier layer on the positive plate is deposited in the draw-off tray greasy dirt particle, and can not rests on the pole plate under the effect of gravity.The utility model adopts the unit-combination type structure, makes the body resistance very little, applies the pulse voltage of special waveform simultaneously on electrode, and plasma active ingredient and pollutant component are interacted, and becomes harmful in harmless.The indication that this system provides operate as normal, fault and needs to clean three kinds of states.Help the user in time to understand equipment running status, guarantee the equipment body long-term stable operation.Therefore, the utility model not only can degrade efficiently oil smoke molecule, dispelling abnormal flavor, non-secondary pollution, and exempt to clean, belong to real environmental protection type oil fume clearing machine.
