Abstract
The invention discloses a kind of condensing oil-water separation methods, it is characterized in that different with the freezing point of water by oil, within the temperature range of oil reaches freezing point and water and not up to freezing point, realize that oil is separated with the efficient oil liquid of water, so that the present invention has structure novel, mention oil it is high-efficient, it is fuel-displaced purity is high the advantages that.
Description
Technical field
The present invention relates to oily water separation technique field, specifically a kind of condensing oil-water separation method.
Background technique
It is well known that the separate mode of existing oily water separating equipment be broadly divided into Gravity separate, it is centrifugal separation,
There is respective substantive defect in electrically separated, adsorbing separation, dissolved air flotation etc., these water-oil separating modes, when water-oil separating
Between it is long, to propose oily low efficiency, fuel-displaced purity low, if Gravity separate mode uses settling tank form, will lead to liquid flowing and exist
Dead zone, partially liq cannot flow displacement, and organic matter can gradually corruption foul in water；Dissolved air flotation mode can generate a large amount of smelly
Gas；Centrifugal separate mode equipment dynamic component maintenance is difficult, is only applied to the analytical equipment etc. in laboratory at present.
In addition, the grease that above-mentioned separation method is isolated causes oil product poor since separation is not thorough, storage and recycling are tired
It is difficult.
Summary of the invention
It is an object of the invention to solve the deficiencies in the prior art, provide that a kind of method is simple, the water-oil separating time is short, mentions
The condensing oil-water separation method of high-efficient, the fuel-displaced purity is high of oil.
The technical solution adopted by the present invention to solve the technical problems is:
A kind of condensing oil-water separation method, it is characterised in that it is different with the freezing point of water by oil, reach freezing point in oil and
Within the temperature range of water and not up to freezing point, realize that oil is separated with the efficient oil liquid of water,
Condensing oil-water separation method of the present invention is obtained by following steps:
1, cold plate is made；
2, cooling condensation is carried out to cold plate, so that the temperature of cold plate is higher than the freezing point of water and is equal to or less than oily solidification
Point；
3, condensed cold plate bottom surface is placed to and is contacted the liquid upper surface in the cabinet for filling oil liquid after static, it will
The oil for being suspended in liquid surface is condensed into grease and adheres on cold plate；
4, the grease being adhered on cold plate is struck off with oil scraping plate；
Since the buoyancy of oil is greater than water and sundries and it is suspended in liquid surface, above-mentioned 1-4 step is repeated repeatedly, i.e.,
Oil-water residue can be separated thoroughly, significantly improve and propose oily purity and propose oily efficiency.
The invention also includes steps 5: the degreasing tank after striking off is heated so that grease heating after formed liquid oil and
It flows rapidly into and connects in oil drum.
Step 1 cold plate of the present invention is made of plate and cold plate evaporator, and the cold plate evaporator is fixed on flat
On plate, the cold plate evaporator is connect with heat pump system, and the heat pump system is connect with temperature detect switch (TDS), and the plate is by leading temperature
Material is made.
Step 5 degreasing tank of the present invention be by groove body and groove body below oily cool condenser constitute, it is described oil condensation
Device is connect with heat pump system.
Temperature detect switch (TDS) of the present invention can use PLC controller, to have the function that automatic control.
The present invention due to use the above method, have structure novel, mention oil it is high-efficient, it is fuel-displaced purity is high the advantages that.
Specific embodiment
Below with reference to examples illustrate the present invention.
A kind of condensing oil-water separation method, it is characterised in that it is different with the freezing point of water by oil, reach solidification in oil
It puts within the temperature range of water and not up to freezing point, realizes that oil is separated with the efficient oil liquid of water,
Condensing oil-water separation method of the present invention is obtained by following steps:
1, cold plate is made；
2, cooling condensation is carried out to cold plate, so that the temperature of cold plate is higher than the freezing point of water and is equal to or less than oily solidification
Point；
3, condensed cold plate bottom surface is placed to and is contacted the liquid upper surface in the cabinet for filling oil liquid after static, it will
The oil for being suspended in liquid surface is condensed into grease and adheres on cold plate；
4, the grease being adhered on cold plate is struck off with oil scraping plate；
Since the buoyancy of oil is greater than water and sundries and it is suspended in liquid surface, above-mentioned 1-4 step is repeated repeatedly, i.e.,
Oil-water residue can be separated thoroughly, significantly improve and propose oily purity and propose oily efficiency.
The invention also includes steps 5: the degreasing tank after striking off is heated so that grease heating after formed liquid oil and
It flows rapidly into and connects in oil drum.
Step 1 cold plate of the present invention is made of plate and cold plate evaporator, and the cold plate evaporator is fixed on flat
On plate, the cold plate evaporator is connect with heat pump system, and the heat pump system is connect with temperature detect switch (TDS), and the plate is by leading temperature
Material is made.
Step 5 degreasing tank of the present invention be by groove body and groove body below oily cool condenser constitute, it is described oil condensation
Device is connect with heat pump system.
Temperature detect switch (TDS) of the present invention can use PLC controller, to have the function that automatic control.
Embodiment: at work, PLC controller powers on the present invention, and refrigerating and heating systems are to cool solidifying plate refrigeration and right
Except oil condenser and water-cooled condenser heat, when cold plate reaches assigned temperature, the assigned temperature be higher than the freezing point of water and
Equal to or less than the freezing point of oil, cold plate downlink is contacted with liquid level, and the oil of liquid surface is cooling under the action of cold plate to be become
Cold plate is adhered at grease in the following, then lifting cold plate, and the grease below cold plate is scraped into oil scraping plate and is removed
In oil groove, grease heats through the oily cool condenser below degreasing tank and becomes oil liquid, and the oil outlet through oil removing trench bottom is flowed into
It connects in oil drum.
The present invention due to use the above method, have structure novel, mention oil it is high-efficient, it is fuel-displaced purity is high the advantages that.
