A kind of domestic oil-fat separator
Technical field
The invention belongs to waste process fields, are a kind of Household oil-water separators specifically.
Background technology
With the development of the social economy, people’s lives level is higher and higher, the oil smoke and oil generated in family life
Water is also more and more.Among oil smoke is discharged into air after smoke exhaust ventilator filtering, but filtered oil smoke still contains part
Grease polluted atmospheric environment although oil smoke is directly expelled to the outdoor living environment for having ensured family.And grease is then
As the sewer pipe connected under every household sink flows into the sewer pipeline system in city, and finally it is gathered together.
The moisture content of these greases is very high, and content of organics is also very big, is easy to grow virus, pathogenic bacteria and cause of disease when temperature is suitable
Microorganism carrys out prodigious threat to the health care belt of people, meanwhile, the organic matter in grease is degenerated decomposition in sewer and also be will produce
Foul gas affects the living environment in city to a certain extent.In addition, there is some businessmans can also be the grease in sewer
It collects to be processed into " gutter oil " and be entrained in edible oil and sell, this edible oil for being doped with " gutter oil " contains largely
Carcinogen and pathogenic bacteria, people can greatly endanger after directly eating to health care belt.But the fat content in oil smoke and grease
Very abundant, these oil recoveries have prodigious utility value later.
There is the oil water separator for being much separated from water the oil in grease on the market, but is all according to oily close with water mostly
Degree is different and simply carries out water-oil separating using gravitational separation process, be also equipped in some oil water separators heating device with
The temperature for improving grease, accelerates the ascent rate of grease.But in grease, grease with can oil slick, dispersed oil, oil emulsion and
The variforms such as dissolved oil exist, merely according to gravitational separation process design that oil water separator can only be in oil-water separation with can oil slick
Grease existing for form, and grease existing for being unable in oil-water separation in the form of other, lead to the inefficient of water-oil separating.
Dissolved air flotation technology is by the way that bubble source is arranged in grease, continuously generates a large amount of bubble, these bubbles are in oil
The tiny oil droplets to suspend in water can be made to be adsorbed on bubble during rising in water, and float up to the table of grease with bubble
Face.This method can make the grease under the suspended states such as the oil emulsion for being not easy to float move to the surface of grease, so as to by grease
In grease separation.Airfloat equipment such as ejector flotation machine special at present, the operating costs such as centrifugal floatation sorting machine are high, equipment volume
Greatly, the deoiling treatment of all uncomfortable household castoff, but it is the basic of dissolved air flotation technology that bubble, which is introduced into oil water separator,
Place.Therefore it needs to design a kind of oil water separator that can be introduced bubble by simple mode, improves the separation effect of grease
Rate.
