Abstract
An oil-water separating device for fatty acid wastewater comprises a waste liquid separator (1), a waste oil tank (2), a waste oil pump (3), a wastewater collecting well (4), a wastewater lifting pump (5), a sewage collecting well (6) and a sewage lifting pump (7), wherein a liquid outlet of the wastewater collecting well is connected with a liquid inlet of the waste liquid separator through the wastewater lifting pump; a water oil outlet of the waste liquid separator is connected with an inlet of the waste oil tank; a water oil outlet of the waste oil tank is connected with an inlet of the waste oil pump; a sewage outlet of the waste liquid separator is connected with an inlet of the sewage collecting well; and a sewage outlet of the sewage collecting well is connected with an inlet of the sewage lifting pump. The oil-water separating device for the fatty acid wastewater can separate grease, fatty acid, fatty alcohol and other materials from vacuum wastewater generated in the production of fatty acid for recycling, and can reduce the oil content and COD in the sewage and the running cost of a sewage station.
Description
Technical field
The utility model relates to a kind of sewage oil removal facility of oil and fat chemical industry, a kind of oily-water seperating equipment of lipid acid waste water.
Background technology
In the oil and fat chemical industry, thereby utilize negative pressure rectifying that material is carried out the carbochain cutting and obtain needed product, this method can reduce energy consumption greatly, but owing to containing the materials such as a small amount of grease, lipid acid, Fatty Alcohol(C12-C14 and C12-C18) in the vacuum waste water, so that the COD content in the waste water obviously increases, increased the difficulty of wastewater treatment.There is no at present the device of materials such as being exclusively used in the oil that separates in this waste water, acid, alcohol.
Summary of the invention
The utility model is intended to propose a kind of oily-water seperating equipment of lipid acid waste water, the oil in the sewage, acid, alcohol etc. can be recycled, and oleaginousness and COD in the reduction sewage.
The oily-water seperating equipment of this lipid acid waste water comprises waste trap, sump tank, scavenge oil pump, waste water pump well, waste water lifting pump, sewage collecting pool and sewage pump, the liquid outlet of waste water pump well links to each other with the fluid inlet of waste trap by the waste water lifting pump, the waste oil outlet of waste trap links to each other with the import of sump tank, and the waste oil outlet of sump tank links to each other with the import of scavenge oil pump; The sewage outlet of waste trap links to each other with the import of sewage collecting pool, and the sewage outlet of sewage collecting pool links to each other with the import of sewage pump.
The feed separation such as the grease in the vacuum waste water that the oily-water seperating equipment of this lipid acid waste water produces in lipid acid being produced, lipid acid, Fatty Alcohol(C12-C14 and C12-C18) are out recycled, and reduce oleaginousness and COD in the sewage, reduce the running cost of sewage plant.
Description of drawings
Accompanying drawing 1 is the schematic diagram of the oily-water seperating equipment of this lipid acid waste water.
Embodiment
As shown in the figure, the oily-water seperating equipment of this lipid acid waste water comprises waste trap 1, sump tank 2, scavenge oil pump 3, waste water pump well 4, waste water lifting pump 5, sewage collecting pool 6 and sewage pump 7.The liquid outlet of waste water pump well 4 links to each other with the fluid inlet of waste trap 1 by waste water lifting pump 5, and the waste oil outlet of waste trap links to each other with the import of sump tank 2, and the waste oil outlet of sump tank links to each other with the import of scavenge oil pump 3; The sewage outlet of waste trap 1 links to each other with the import of sewage collecting pool 6, and the sewage outlet of sewage collecting pool links to each other with the import of sewage pump 7.
Waste water pump well 4 and sewage collecting pool 6 in the oily-water seperating equipment of this lipid acid waste water can be embedded in underground.Waste water A in the Vacuum Heat trap in the lipid acid production is collected in the waste water pump well 4 by trench 8, then delivered to waste trap 1 by waste water lifting pump 5.The internal structure of waste trap adopts the 316L stainless steel tube as coalescence material, adopt inclined tube-type counter-current separation technology, has mixing, the integrated function of reaction and breakdown of emulsion, utilize oil to carry out oily water separation with the difference of water two-phase character with to the characteristic that the coalescence material surface affinity differs greatly, when oily(waste)water when filling the bed of coalescence material, elaioleucite is stranded in material surface and the hole by material capture, thicken along with the elaioleucite thing of catching and form oil film, when reaching a certain thickness, oil film will produce distortion, assemble to merge and form larger oil droplet, thereby oil is separated from aqueous phase, be integrated into the top of waste trap.Isolated waste oil is collected in the sump tank 2, then is sent to recovery oil tank C by scavenge oil pump 3 and recycles; Isolated water is sent into sewage collecting pool 6, then sends to sewage works D by sewage pump 7 and carries out biochemical treatment.Water oleaginousness after waste trap 1 is processed is not more than 500mg/L, because most of oil is separated, so that the oleaginousness of sewage and COD reduce greatly, thereby has reduced the running cost of sewage plant.The waste liquid that waste trap 1 bottom settlings produces is back in the waste water pump well 4 through trench 9.A plurality of outlets are arranged at waste trap 1 bottom is better to blow out separator with steam for the settling (being distributed in different positions) with the separator bottom.
Waste trap 1 in the oily-water seperating equipment of this lipid acid waste water is operation with pressure, and this pressure is provided by waste water lifting pump 5, and the waste oil in the waste trap enters in the sump tank 2 from the Base top contact of waste trap.A plurality of outlets are arranged at the top of waste trap, and waste liquid carries out separating for several times in separator, can reach better separating effect.Through transferring out after the precipitation, separate from the bottom of sump tank again by the waste liquid that precipitation produces in sump tank 2 for waste oil, is back in the waste water pump well 4 through trench 9.B is low-pressure steam among the figure, is used for purging the residue of accumulation in waste trap 1 and the sump tank 2.The liquid level of sump tank 2, waste water pump well 4 and sewage collecting pool 6 can be detected by Level Detection instrument 10,11,12 respectively, and according to liquid level scavenge oil pump 3, waste water lifting pump 5 and sewage pump 7 are controlled, whole wastewater treatment process can adopt concentrated time variable control, automatically operation.Waste water lifting pump 5 and sewage pump 7 can have a plurality of, are connected in parallel, use in turn and overhaul.
