Description

The public flue smoke purifier in commodity building

Technical field: the utility model relates to a kind of cooking fume control equipment, the public flue smoke purifier in especially a kind of commodity building.

Background technology: the technology that is in of flue oil smoke mainly contains following several at present:

1, (mechanical type) inertial separation method: the mechanical type cooking fume remover is meant the cooking fume remover that utilizes the mechanical type technology for cooking fume control to make, and the mechanical type technology for cooking fume control is to utilize mass force effects such as gravity, inertia force, centrifugal force to finish the technology of fume purifying process.Mechanical type technology for cooking fume control commonly used comprises technology such as traditional hydro-vent, centrifugal oil remover, inclined rodbank, cyclone dust removal, inertia force dedusting.Early stage at fume purifying, this mechanical type cooking fume remover is more common.This class cooking fume remover usual earlier adopts mechanical barrier class purification techniques such as composite web, inclined rodbank on the market, the steel wire that has part enterprise to adopt high speed to rotate is in the recent period tackled the larger particles composition in the oil smoke, belong to the centrifugal lampblack purification techniques, man of part Kitchen Utensils Factory has the ability of making hydro-vent simultaneously, and hydro-vent then is the product that combines water droplet inertial dust collection and two kinds of technology of centrifugal force dedusting.Generally speaking, filter oil smoke with mechanical barriers such as net or water exactly.Relative other cooking fume remover, the characteristics of the mechanical type cooking fume remover of mechanical type technology for cooking fume control manufacturing be simple in structure, be easy to make, cost is low, be convenient to safeguard and equipment resistance less, the smoke particle pollutant of the above order of magnitude of micron is had higher detergent power.If adopt the cooking fume remover of mechanical type technology for cooking fume control reasonable in design, configuration is installed suitably, the specification requirement that its fume purifying ability reaches GB 18483-2001 regulation is fully possible.Handle through qualified mechanical type technology for cooking fume control, can guarantee the long-term not oil-collecting of fume pipeline and the long-term effect of not hanging oil of exhaust opening basically.But the defective of mechanical type cooking fume remover is powerless to the pollutants from cooking fume of the following order of magnitude of micron, important component part for pollutants from cooking fume---pollutant aerosol does not possess detergent power basically, therefore uses the mechanical type technology for cooking fume control not meet the demands separately in the occasion that requires smokeless emission.

2, common filtration method: the operation principle of common filtration method is to make oil smoke gas by filtering material, and the smoke particle thing is caught to combine in the filtrate under collision, interception and the diffusion of filtrate and is purified.The key of this technology is that the higher polymer composite of oil absorbency is generally selected in the selection of filtrate for use, and wherein activated carbon application is the most extensive.When soot gas when the filtering oil smoke layer, the granule aerosol of filter course in can the adsorbed oil flue gas, and smell had obvious catharsis.But general firm advantages of good adsorption effect when beginning to install, along with adhering to of oil smoke mist, adsorption capacity can weaken gradually.On the whole, the advantage of this filtration method is that investment is little, purification efficiency is high, reaches usually more than 80%, stable and reliable operation, but because the particle viscosity that filtrate captures is higher, all be difficult to clean by common flow by gravity or extruding removing, filtrate easily stops up, and pressure drop is bigger, and up to 1500Pa, and floor space is big as the pressure drop of glass fibre bed, can only be installed in outdoor, filtrate needs periodic replacement, the operating cost height, and these problems make the application of this filtration method be subjected to certain limitation.

3, liquid scrubbing method: the liquid scrubbing ratio juris is that oil smoke gas is contacted with absorption liquid by special distribution device in gas-fluid, the particle in the oil smoke gas is removed to liquid phase from gas phase, thereby reaches the purpose of purification.According to the difference of the gas-liquid way of contact, can be divided into three kinds of liquid film type, fountain and impact types.The liquid film type fume purifier of fume, its principle is to form water smoke, moisture film by the space of special nozzle in cover, after oil smoke is drawn onto in the cover by the air-introduced machine negative pressure, the mist of oil particle fully contacts with water smoke, moisture film, stick on the water droplet through effect of inertia, crown_interception, diffusion, the gravity of water droplet dependence itself drops on the end plate washer of cover, bottom baffle tilts to the groove of cover the inside, after the water that has adhered to oil droplet flows to groove, flow to cyclic water tank by return pipe, water tank is made the held concurrently effect of oil interceptor of special form.Because the proportion of oil is less than water, oil droplet relies on the buoyancy of self to rise to the water surface, is gathered into oil reservoir and gets in the cover by circulating pump and recycle.The clean-up effect of wet purification method is than higher, and can remove the SO2 in the oil smoke, CO2, and waste gas such as NOx, but wet scrubber is to the particle purifying efficient lower [9] of submicron order; Scrub raffinate fails better to solve, and directly scrub raffinate is entered sewer at present, produces secondary pollution; The consumption of cleaning solution usually causes increasing of operating cost in addition.

4, static fume purifies: the applying high voltage electrostatic principle, adopt many electric fields module combinations technology, with oil smoke, thermal cracking cloud, fuel flue dust electric charge, absorption and the oxidation under static and effect of electric field that produces in the cooking process, the effect that reaches purifying oil fume, removes flue dust, removes peculiar smell, the ozone that is produced in the electric field can also sterilization, removes peculiar smell and pernicious gas.The cooking fume remover that utilizes high-pressure electrostatic development has bigger superiority and application prospect than the cooking fume remover of wet type cooking fume remover, filtering type.Principle: electrostatic oil and smoke cleaner has " high altitude discharge type " and " low latitude emission type " two kinds; It utilizes the direct current high voltage electric field to produce the corona discharge phenomenon, oil smoke to the clarifier of flowing through carries out the ionization decomposition, form small charged elaioleucite and cigarette, dirt, water particle, through the dull and stereotyped dust arrester of heteropolarity the time, be absorbed, deposit at last in the bottom fuel reserve tank of clarifier and and discharge through conduit.Simultaneously, because the ozone that corona discharge produces has the sterilization effect of eliminating the unusual smell, oil smoke is fully purified.Characteristics: complete machine structure is reasonable in design, standard modular design, the capture and the clean-up effect of raising elaioleucite; Energy consumption is little, low noise; Interchangeability is good, installation and maintenance and easy to use.Parameter: be suitable for cooking stove: 2～12; Handle air quantity: 4000～30000m3/h; Power: 0.9～2.0KW.As seen static fume purified treatment amount is less, is not suitable for large-scale public flue.
