Description
Technical field
The invention belongs to field of Environment Protection, relate in particular to a kind of kitchen oil fume purifying processing method, is a kind of fume purifying method for kitchen and device specifically.
Background technology
The enhancing to ecological environmental protection consciousness along with social development and the mankind; people talk at present " haze " look and become; because exceeding standard, outdoor air quality PM2.5 becomes normality; and the outer row of kitchen fume has made the matter worse to the weak air quality that is highly brittle at present, very distinct issues are become.The discharge of kitchen fume shows from overall situation, according to Chinese Academy of Sciences's atmospheric physics institute monitoring, in the source of Beijing PM2.5, the discharge ratios such as kitchen fumes have accounted for 13%, even higher than 8% of industrial discharge, this is that family kitchen quantity absolute value determines and causes the variation of matter.Consider from kitchen subenvironment, particularly some middle-size and small-size food and beverage enterprises, the index of PM2.5 in kitchen is far beyond the more than 10 times of outdoor air quality, once and particle in these oil smoke of human body Long Term Contact, not only can cause skin senescence, even also can improve the risk of suffering from cancer, it is extremely urgent solving as can be seen here the problem of oil smoke in kitchen.
Civilian kitchen fume treatment technology, great majority adopt mechanical system to carry out oil removing, peculiar smell are not processed.Traditional mode utilizes the fan blade of High Rotation Speed to cut floating trickle oil droplet in air, and making it cohesion becomes in oarse-grained greasy dirt inflow store oil box, and fumes peculiar smell is not directly passed through to pipeline external discharge through walls through any processing.
Same commercial kitchen oil smoke treatment technology, adopt the blower fan of Wind Volume High Rotation Speed, oil smoke inspiration fume purifier of fume, device ground floor adopts stainless steel wire braiding coarse filtration net, the second layer is Electrostatic Absorption or plasma, the 3rd layer for charcoal absorption, gas again by pipeline to outdoor discharge.In recent years, also having occurred some new technologies on market, as light degradation technology, is that the wavelength that utilizes quartz burner to send 100-280 nanometer produces ozone, the airborne odoring substance of oxidation Decomposition and gaseous organic compound; Also adopt in addition atomized water spray in pipeline, produce moisture film and eliminate and separate oil smoke, no matter adopt which kind of oil smoke treatment technology, all be unable to do without brokenly wall, discharge pipe, erect chimney, to disturb residents and take high as far as possible smoke stack emission in order to reduce.
The fume purifier of fume of catering industry, no matter adopt what technology, all be unable to do without flue gas utilization chimney after treatment or building flue to outdoor discharge at present, causes outdoor air quality constantly to worsen.If can not regularly fume pipeline be cleaned, can give hiding some dangers for of fire.
