Abstract

The utility model relates to a compound plasma oil fume purifier that is characterized in including a shell, homogeneous liquid, an oil mist agglomerating and harmful air decomposing section and a rotary stream divider; oil mist and fume enters the oil mist agglomerating and harmful air decomposing section after processed with the homogeneous liquid; under the effect of low temperature plasma produced during the discharge by the plasma generator space, the oil mist grains are agglomerated and gathered on a rotary stream body wall and then flows to an oil collecting box under gravity effect. The utility model has an oil removal rate of higher than 80 percent and a peculiar smell removal rate of higher than 70 percent; besides, no adhesive oil exists, which avoids the problem of decreased efficiency caused by adhesive oil on the static oil removing board and line.

Description

Composite plasma body cooking fume remover

Technical field:

The utility model relates to that a kind of to use the polymerization of low temperature plasma and oxidisability be cardinal principle, and the tiny oil droplet in the oil smoke is carried out charged cohesion, simultaneously with the composite plasma body cooking fume remover of gasified harmful substance oxidation or decomposition.

Background technology:

In the traditional Fried, fried, cooked, fried process of China, can produce a large amount of oil smoke, according to relevant department's analysis and measurement, contain in the oil smoke in a large number to human body and the harmful material of atmospheric environment, for example: grease, protein and raw material seasoning matter carry out physical-chemical reaction and organic flue gas of producing under heating condition, also have heating operation process drop to spatter the macromolecular compound that splits the decomposition of oil plant material, oxidation, polymerization, therefore the existing suspended particulate substance of state that exists has the organic pollutant with gas molecule again.Mainly be divided into unsaturated hydro carbons, saturated hydrocarbons, benzene series thing, polycyclic aromatic hydrocarbon, heterocyclic compound and alcohol, aldehyde etc., kind more than 200 is specifically arranged.Add that the pollution that fuel produces in the operation room can form the ternary pollution of gas, liquid, solid, wherein the taste in the oil smoke mainly is that gaseous contaminant is done.Multiring aromatic hydrocarbon etc. is a carcinogenic substance in the oil smoke dirt, and these materials form the aerosol that is difficult for diffusion and is difficult to sedimentation in atmosphere, the dense population areas The Surroundings in Cities has been caused great harm.At present, the oil smoke treatment measures mainly contain inertial separation equipment, electrostatic precipitation equipment, filter plant and washing facility etc. both at home and abroad.Though above the whole bag of tricks has solved certain problem in the pollution problem of oil smoke to atmosphere, but all exist not enough and potential secondary pollution problem separately, inertial separation equipment is made up of grid, mist of oil guard, it is that change by the flue gas direction makes oil mist particles lean on inertia to separate from air-flow, this kind equipment is simple, pressure drop is less but purification efficiency is not high, and invalid fully to removing pernicious gas and peculiar smell.Owing to contain the ternary polluter of gas, liquid, solid in the kitchen exhaust simultaneously, no matter to capture the material viscosity of getting off but very big for the sort of method, so electrostatic precipitation equipment and filter plant all exist not long characteristics effective acting time, and there is extremely difficulty of cleaning in electrostatic method, problems such as operating cost height, it is higher that washing facility is handled oil smoke efficient, also can remove the part peculiar smell, but the circulation of cleaning solution also is very limited, its blowdown is bigger to the harm in water source and soil, if the user does not add the cleaning solution additive, the equipment oil removal rate is just near zero so.

Technology contents:

The purpose of this utility model is exactly to determine that polymerization and oxidisability with low temperature plasma are that guiding theory is carried out the design of product, and plasma is a kind of state (being commonly called as the 4th attitude) that material exists.Different with common gaseous state, in plasma state, component be charged ion rather than neutral molecule.Plasma state exists in a large number in the cosmic space, the hot celestial body just formed by plasma fully of the sun for example, and this plasma is because the high-temperature plasma of thermonuclear reaction generation.Composite plasma body cooking fume remover described in the utility model is the low temperature plasma that utilizes the space discharge generation.Its mechanism is: contain a large amount of opposite polarity ions in the plasma, can be attached on the oil droplet, thus impel the oil droplet cohesion to be easy to capture effectively, the plasma of space discharge generation contains the very strong free group of a large amount of activity as OH, O, HO ₃And strong oxidizer O ₃Effective oxygen attitude harmful components in the oxidation oil smoke.Course of reaction with the Low Temperature Plasma Treating oil smoke is: tiny oil droplet → charged cohesion → sedimentation or capture; Gasified harmful substance matter → oxidation or decomposition → sedimentation or capture.Its structure is made up of four parts: housing, equal fluid, mist of oil cohesion and pernicious gas decompose section, rotational flow separation body.Housing is a closed box that equal fluid, plasma generator and rotary fluid are combined, and the left side of housing is an air inlet, and the right-hand member top is an air outlet, and the bottom is an oil sump tank; The current-sharing body is positioned at housing Inner Front End portion, and the air inlet place is two and parallels, and with housing bottom, the parallel square louver board in top, two boards is separately fixed on the housing sidewall, left end links to each other with air inlet, right-hand member is blind dead, and the housing Inner Front End partly is slit into three spaces; Mist of oil cohesion and pernicious gas decompose the place, upper and lower two spaces that section is positioned at equal fluid two boards and inner walls formation, and two plasma generators are separately fixed on the upper and lower inwall of housing; Rotary fluid is positioned at the cylindrical drum of being made up of two 3/4 concentric circles column casings that do not waited by a plurality of diameters respectively the housing right part and constitutes, and the top links to each other with air outlet, and the lower end links to each other with oil sump tank.After oil-containing fog dust gas enters clarifier by air inlet, at first, remove big oil mist particles by equal fluid, reduce because the inhomogeneous oil mist concentration that produces in the cooking process to the efficient fluctuation of cohesion and decomposition section, makes the life-span of generator longer, efficient is higher.After oil-containing fog dust gas enters mist of oil cohesion and pernicious gas decomposition section, under the low-temperature plasma effect that the discharge of plasma generator space is produced, adopt mechanical means that it is caught oil mist particles cohesion back, the oxidized decomposition of pernicious gas simultaneously, peculiar smell is removed, cyclone separator is the direction of motion that changes the bulky grain mist of oil that has condensed, and makes it to be aggregated on the eddy flow body wall, and flows under the influence of gravity into oil sump tank and be collected.

This composite plasma body cooking fume remover main feature is that its resistance approaches zero in its course of normal operation.Because oil removing that equipment adopts and the mechanism that eliminates the unusual smell are different from the filtering type clarifier, so the complete machine resistance substantially not in time length and change, its oil removal efficiency all is higher than more than 80% at present, and eliminating the unusual smell reaches more than 70%, and the generator maximum selects for use power to be not more than 50W.Since the not sticking oil of generator itself and cohesion oxidation panel, the decrease in efficiency problem of having avoided static oil removing pole plate, the sticking oil of polar curve to be caused.
