Oily Sludge Harmless Treatment System
Brief IntroductionChanging the physical & chemical properties and components of the sludge particles,Website:, destroying it’s colloidal structure, reducing it’s affinity with water, improving dewater ability and de-oil performance through conditioning the sludge. to realize complete separation among oil, water and solid content.Pyrolysis process is a new technique of oily sludge harmless processing.The working principle is based on high temperature heating, it should dry the sludge as much as possible before pyrolysis, then put it into rotary kiln with 500-600℃ heating temperature, spray nitrogen at the mean time to separate oil and water.Oily sludge pyrolysis process has following advantages: --Process equipments don’t have to endure high temperature or high pressure, it has lower investment and much lower operation cost than incineration process;--High energy recovery rate, product of pyrolysis is liquid oil which is convenient in storage, solid residue has high calorific value --Heavy metal is concentrated inside the solid content after process, non-condensable gas amount is little, NOx, SO2 or Organic chloride amount are littleApplicationOil field Sludge, tank bottom oily sludge, oil base mud etc.Process Layout
