Description
Technical field
System is utilized the present invention relates to atmosphere pollution process for comprehensively treating field, more particularly to a kind of oil flue waste gas gradient.
Background technology
The various chemical substances contained in oil flue waste gas, such as aldehyde, ketone, hydrocarbon, aliphatic acid volatile organic matter and tiny oil
Fog particles, wherein many volatile organic matters are acted on " carcinogenic, teratogenesis and mutagenesis ", while being photochemically reactive decision
Property precursor, is also the important sources of the Secondary Organic particle in PM2.5, and important shadow is all produced to health and surrounding air
Ring.In recent years, country paid attention to and increased the management and control of volatile organic matter, and volatile organic matter implements overall control into certainty
Trend.Therefore, the pollution of control oil flue waste gas is significant.
Oil flue waste gas cooking fume control equipment in the country's mainly includes that mechanical oil purification equipment, filtering type fume purifying set at present
Standby, wet cooking fume purifying equipment, equipment for purifying oil-fume etc..All of the above mode, except minority make use of chemical method
Outward, the method that physics is belonged to greatly, they are mainly solid state class material and the operative liquid class larger to particle size in oil smoke
Material has certain separation, absorption and deposition, and they are trapped in inside these purifiers, and these sooty substance sheets
Body is not broken off, and they can constantly be accumulated in purifier, under causing the efficiency of purifier and the continuous of effect
Drop, therefore has to continually clean or change these purifiers.Meanwhile, more seriously, these methods are to oil smoke
In those removal effects to air pollution and the great gaseous volatile organic matter (VOCs) of human health damage it is very limited,
Major part has still finally been discharged into air because cannot effectively remove.
Gross contamination emission is the product of exhausted air quantity and Pollutant emission concentration.The various atmosphere pollutions of present
Discharge standard generally only controls the concentration of emission of pollutant, and as the key factor of control gross contamination emission --- it is useless
Tolerance emission reduction does not cause enough attention.Therefore, traditional cooking fume control equipment has no positive effect to exhausted air quantity emission reduction.But it is actual
The emission reduction of upper exhausted air quantity plays an important roll for the reduction of gross contamination emission, and exhausted air quantity emission reduction can not only controlled on an equal basis
The discharge of pollutant is reduced under technical conditions processed, while the emission reduction of exhausted air quantity also tends to mean the reduction of the air amount of taking, row
The reduction of gas heat loss and the raising of efficiency, therefore exhausted air quantity emission reduction often has the double action of energy-conservation and emission reduction simultaneously.
