Being not less than 60,000,000 tons, big and medium-sized cities changing food waste yield is the most surprising, and annual production has just exceeded 6,400,000 tons, Chongqing, Beijing,
The urban issues that the catering trades such as Guangzhou are flourishing is the most serious.Unscientific process changing food waste not only results in environmental pollution, harm
Resident is healthy, is also the huge waste to resource simultaneously.
Changing food waste have high-moisture, high salinity, high oils and fats, high organic content, component space and time difference substantially, hazardness with
Resource the feature deposited, changing food waste into resources causes country's great attention in recent years.The main pin of original oily water separation technique
To mineral oil, and there is bigger difference in the physical property characteristic of changing food waste and mineral oil, causes oil-water separation inefficient；Meanwhile,
Owing to the recovering state of changing food waste is poor, cause changing food waste entirety recycling treatment ratio relatively low, such as Beijing 2014
The changing food waste daily output is more than 2200 tons, and recycling treatment amount is only 540 tons, less than 25%；The Shanghai kitchen rubbish of 2014
The rubbish daily output is more than 2000 tons, and actual freight volume of receiving only has 1100 tons.
Stokes' law is that fluid flows for spheroidal particle settlement law in a liquid during laminar flow.As a diameter of d spherical
When grain settles in a liquid, the sedimentation velocity of granule is u0=d3(ρs-ρ) g/18 μ (wherein, u0For sedimentation velocity, unit:
m/s；D is particle diameter, unit: m；ρsFor grain density；ρ is fluid density, unit: m3/kg；δ is resistance coefficient,
Zero dimension；Re is Reynolds number, zero dimension；μ is viscosity, unit: Pa s).When oil-water separation, work as u0< when 0, oil droplet
Float, lamination occurs, and with u0Increasing, the speed that oil droplet floats gradually rises, thus improves oil-water separation efficiency and carry
High.According to Stokes' law: the ascent rate u0 of oil droplet and the diameter d of oil droplet square is directly proportional, with disperse medium
Density contrast (ρ with suspension oil droplets-ρ) be directly proportional, be inversely proportional to the viscosity, mu of solution, i.e. droplet diameter d increase, disperse medium and
Poor (the ρ of density of suspending liquids-ρ) increase, viscosity, mu reduces, and ascent rate increases.Analyze accordingly, for improving oil-water separation efficiency, i.e.
Increase the ascent rate of oil droplet, can be from the standpoint of increasing disperse medium and the density contrast of suspension oil droplet, reducing viscosity the two.
