Method.
Background technology
With the fast development of Chinese society economy, people's living standard is improved constantly, the amount of kitchen castoff also with day
All to increase, wherein most all becomes changing food waste and is effectively recycled, not only has a strong impact on urban environment and make
Into the serious wasting of resources and numerous food safety hidden danger, wherein the food brought with kitchen waste grease (i.e. waste oil) is pacified
Full problem goes out the most.The high pulpous state kitchen castoff of moisture content realizes the separation of oils and fatss substantially after oil-water separation process
With collection, that is, removing oil link is completed, follow-up deep processing link could be entered.Therefore, oil-water separation is processed in kitchen waste grease
Very important status is occupied in recycling.
It is not to aim at the recovery of kitchen waste grease and design, base although existing oily water separation technique species is more
Be both for the mixed system of crude oil or mineral oil and water in sheet, and kitchen waste grease (containing animal oil) in composition with
Mineral oil has very big difference, and the specially animal oil content in kitchen waste grease in solid phase is higher.Bulk solid-state, adhesion
Animal oil (the such as tallow oil of caking) on solid phase kitchen castoff surface is poorly soluble, thus can not be formed fluid oil
To put into follow-up deep processing link, so that the oil recovery utilization rate of kitchen castoff is not high.And kitchen waste grease its
Composition mostly is fatty acid triglycercide, thus with the polarity more higher than mineral oil, so bigger with the separating difficulty of water.
At present existing oily-water seperating equipment and method all lay particular stress on oils and fatss in removing water, rather than the oils and fatss in water are enriched with
Come.Additionally, the separating effect of single oily water separation technique is generally relatively low.
