It comes into full contact with, the mist of oil particle in oil smoke is thus made to form the oil-in-water fog particles wrapped up by water mist, that is, oil-in-water
Particle is the aerosol of dispersed phase, and to convert the purification of oil smoke to demisting purification, this reduces cooking fume purifications
Difficulty.Water mist that oil-in-water fog particles are sprayed by equipment nozzle, moisture film, and by inertia, retention, diffusion with water droplet
Flow into water tank.After water oil mixture reaches saturation, the oil reservoir on surface can be scraped off recycling.This purification method
For purification efficiency up to 80% or so, pressure drop is smaller, stable, and cleaning easy to maintain takes up space smaller.But in the process of running
Equipment needs power consumption, Jia Shui (detergent) to be less suitable for being used for a long time so expense is larger, and has the problem of secondary pollution.It utilizes
The detergent containing ingredients such as surfactant, alkali can be added, so that it may substantially carry in the hydrophobicity of oil smoke droplet in slurry
The efficiency of high fume purifying.This method cost of equipment is low, and operation and maintenance amount is small, and floor space is small, economy is high.But because lack conjunction
Suitable absorbent of oil fume, and lack the technology of waste liquid after-treatment and develop limited.
Therefore, research and develop that a kind of fume eliminating is efficient, kitchen oil fume purifying chaotropic agent cost-effective and environmentally friendly is extremely important.
