Description
Technical field
The invention belongs to kitchen garbage process field, more particularly, to a kind of Kitchen waste filtrate oil removing pot and its oil removing system
System.
Background technology
About containing 3% animal and plant fat in Kitchen waste filtrate, 35%~45% is about contained in hogwash fat or gutter oil
Animal and plant fat, as it is recyclable recycling resource, it is necessary to be efficiently separated and recycled to it.
Kitchen waste filtrate will subsequently enter anaerobic system, but the grease (long chain fatty acids) in kitchen filtrate can suppress to detest
The activity of microorganism in oxygen system, so as to influence anaerobism effect, therefore kitchen filtrate enter anaerobic system before be necessary to be removed
Oil.
Grease can be sufficiently separated under heated condition (30 DEG C~70 DEG C) with moisture in filtrate, since density is different, oil
Fat is located at upper strata, and moisture is located at lower floor, so as to reach separated effect.
The grease separation in industry and recovery method mainly add disk centrifugal separator complete with three decanter centrifuges at present
Into, this method mainly use for reference with edible oil processing industry, but be in fact not particularly suited for kitchen garbage treatment industry, it is main former
Because being that fat content is far below oil content in edible oil processing enterprise material in Kitchen waste filtrate, secondly, kitchen garbage is whole
Material enters three decanter centrifuges, causes decanter centrifuge to be in for a long time under high abrasive conditions, can not only reduce centrifuge
Service life, and larger energy consumption can be brought in the process of running.
Another grease separation and recovery method are the damp and hot technology for hydrolyzing of high temperature in industry at present, i.e., kitchen garbage is whole
Thermophilic digestion is carried out, grease is separated under the high temperature conditions from kitchen garbage, carries out oil extraction afterwards.This method is being transported
Need to ensure high temperature (120 DEG C~160 DEG C) state during row, energy consumption is higher, improves oil removing cost.
Also there are a small number of engineering application oil removing pots to carry out oil removing in industry at present, this oil removing pot shape is in cone for bottom
Cylinder tank body, mainly there are following several respects in the drawbacks of upper end oil removing, lower end water outlet, this tank body：
1st, tank body only has a discharge outlet, and solid slag and filtrate together exclude, and can cause draining blockage for a long time；
2nd, at the oil discharge outlet of tank body upper end liquid level diameter as whole tank body, so that oil layer 15 is relatively thin, in oil extraction
When can take the moisture in a large amount of kitchen filtrates out of, so as to get grease moisture content it is excessive；
3rd, existing mode of heating is built-in heating pipe heating, can be corroded for a long time by kitchen filtrate, and exists and add
The non-uniform problem of heat；
4th, the water distribution system style sheet one of tank body, is light water water inlet tube, i.e., the water pipe of single caliber is a part of by feed liquor
Design can make filtrate form horizontal mobilization in tank base, be unfavorable in tank base, this design between pipe outlet
Can oil slick rising, another part tank design is that inlet tube extended to tank body middle and lower part position, this design produce into
Water carries the speed moved upwards, and the oil layer 15 that can make to have produced is broken through, and is unfavorable for follow-up oil removing；
5th, it is in the process of running full closeding state that tank body, which is, it is impossible to intuitively observes 15 position of oil layer in tank, causes
Not exclusively or in the grease gone out moisture content is excessive for oil removing.
The content of the invention
