Description
Technical field
The invention belongs to kitchen waste water processing technology field, particularly relate to a kind of kitchen waste water oil-water separation method.
Background technology
Along with the development of Chinese national economy and the raising day by day of living standards of the people, catering industry has obtained swift and violent development in recent years, and the environmental problem of being drawn by changing food waste becomes increasingly conspicuous.According to Tsing-Hua University's environment, be that solid waste pollution is controlled and the statistic data of Resource analysis institute shows, the changing food waste of the annual generation in China city is not less than 6,000 ten thousand tons.Kitchen waste water claims again swill, the worry that other whereabouts of the not the norm handles of swill and swill and impact cause the public.The wordings such as " swill pig ", " sewer oil " allow people abhor, and swill harm city appearance environment, affects citizen healthy, has become one of focal issue of current China hygienic condition.In kitchen waste water, wherein contain a large amount of materials such as animal-plant oil, these materials can be recycled as the raw material of the products such as biofuel, stearic acid and oleic acid, so changing food waste is also a kind of available renewable resource.It is one of green method solving kitchen waste water problem that grease in kitchen waste water is recycled to also recycling.Oily water separation technique application and research mainly concentrates on oil refining and chemical industry at present, for the processing of picture catering industry this waste oil rare report at home, therefore research and develop efficient kitchen waste water oily water separation technique, for the changing food waste into resources utilization of China provides technical support, there is very important practical value.
In the oil recovery process of kitchen waste water, kitchen waste water is after preliminary solid-liquid separation, under the impact of emulsifying effect, grease is mainly present in the external phase of water with the form of disperse phase, how to make small oil phase drop generation breakdown of emulsion with coalescence, finally realize two separated be the key point of oil recovery.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of simple in structure, the kitchen waste water oil-water separation method that oil-water separation is good.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of kitchen waste water oily-water seperating equipment, comprise gun barrel (4), waste water tank (1) and storage tank (3), and be arranged on gun barrel (4) lower end water inlet pipe (2), be arranged on the water shoot (9) of gun barrel (4) one sides and be connected the oil outlet pipe (8) of gun barrel (4) and storage tank (3), water shoot (9) is connected gun barrel (4) with waste water tank (1).
Gun barrel (4) comprises filler separating layer (6), hydrophilic oleophobic interlayer (5) and the hydrophobic oleophylic screen layer (7) of the portion of setting within it, described filler separating layer lower end is connected with water inlet pipe, the surrounding of filler separating layer is surrounded by hydrophilic oleophobic interlayer (5), and the top of filler separating layer is covered by hydrophobic oleophylic screen layer (7).
In described scheme, filler separating layer (6) is comprised of the random packing of polyolefine material, and the diameter of filler is 1cm-5cm.
In described scheme, hydrophilic oleophobic interlayer (5) is comprised of stainless steel mesh supporting layer and viscose fiber filter layer of cloth, and the order number of stainless steel mesh is 30-100 order.
In described scheme, hydrophobic oleophylic screen layer (7) is the three-dimensional mesh layer of polyolefine material.
Advantage and positively effect that the present invention has are: with respect to prior art, oily-water seperating equipment provided by the invention and separation method technique are simple, easy handling.Adopt the random packing of polyolefine material to divide phase medium as profit, and with hydrophilic oleophobic interlayer and hydrophobic oleophylic screen cloth respectively as the collection channel of water and oil phase, process field at kitchen waste water has broad application prospects, and the while is also for the oily water separation of other industry provides a kind of very important Technical Reference.

Embodiment
As shown in Figure 1, a kind of kitchen waste water oily-water seperating equipment, is characterized in that: described kitchen waste water tripping device comprises water inlet pipe 2, water shoot 9, oil outlet pipe 8, and gun barrel 4, waste water tank 1 and storage tank 3.Described gun barrel comprises filler separating layer 6, hydrophilic oleophobic interlayer 5, hydrophobic oleophylic screen layer 7.Described filler separating layer lower end is connected with water-in, and the surrounding of filler separating layer is surrounded by hydrophilic oleophobic interlayer, and the top of filler separating layer is covered by hydrophobic oleophylic screen layer.Kitchen waste water oily-water seperating equipment provided by the invention be take gun barrel as core parts, gathering centrifugation by filler separating layer realizes the separated of oil phase and water, water is separated and is entered waste water tank via hydrophilic oleophobic interlayer from system, oil phase enters storage tank via hydrophobic oleophylic screen layer, finally realizes the oily water separation of kitchen waste water.
What described filler separating layer adopted is the random packing of polyolefine material, and the diameter of filler is 1cm-5cm.The random packing that filler separating layer adopts is polyolefine material, is specially polypropylene, polyethylene, or one or more in tetrafluoroethylene
Described hydrophilic oleophobic interlayer is comprised of stainless steel mesh supporting layer and viscose fiber filter layer of cloth, and the order number of stainless steel mesh is 30-100 order.
What described hydrophobic oleophylic screen layer adopted is the three-dimensional mesh material of polyolefine material.
Now kitchen waste water oily-water seperating equipment principle of work provided by the invention is described below:
Kitchen waste water, after the pre-treatment such as precipitation and filtration, obtains oil-in-water or water in oil mixed emulsion.Pretreated kitchen waste water enters the filler separating layer of gun barrel inside under the effect of pump via water inlet pipe.According to similar compatibility principle, be all between grease that polarity is less and polyolefine filler and produce stronger interaction force, grease is adsorbed on the surface of polyolefine filler.Due to the density of grease density lower than water, under the effect of buoyancy, grease upwards flows with the form remaining in a standstill at filling surface, until arrive the hydrophobic oleophylic screen cloth of oily water separation tank top, grease sees through mesh and discharges system, in storage tank, collects.In separating filler layer, water is subject to the effect of repulsion around under surface tension effects, and water flows to be similar to the form of turbulent flow in the space of filler.Water is to filler separating layer hydrophilic oleophobic diaphragm movement around under the effect of lateral pressure, and because hydrophilic oleophobic barrier film has very strong wetting ability and water-permeable, water, through outside discharge system after barrier film, is collected in waste water tank.
Example 1
Wastewater source is waste water after certain restaurant changing food waste solid-liquid separation, and the content that enters the front grease of oily-water seperating equipment is 6%(volume fraction), after oily-water seperating equipment is processed, in storage tank, the content of grease is 90%, in waste water tank, the fat content of water is 0.2%.
Example 2
Waste water after wastewater source Wei Mou star hotel changing food waste solid-liquid separation, the content that enters the front grease of oily-water seperating equipment is 10%(volume fraction), after oily-water seperating equipment is processed, in storage tank, the content of grease is 93%, and in waste water tank, the fat content of water is 0.3%.
Above embodiments of the invention are had been described in detail, but described content is only preferred embodiment of the present invention, can not be considered to for limiting practical range of the present invention.All equalization variations of doing according to the scope of the invention and improvement etc., within all should still belonging to this patent covering scope.
