Description
Technical field
The invention belongs to waste oil water process field, particularly relate to a kind of oily-water seperating equipment.
Background technology
After oily(waste)water is discharged to the water bodys such as rivers,lakes and seas, oil reservoir covers the water surface, and the oxygen in prevention air is to the diffusion in water; Because dissolved oxygen reduces in water body, the photosynthesis that algae carries out is restricted; Affect hydrobiological normal growth, make aquatic animals and plants have oily taste or toxicity, even make water body foul, destroy the utility value of water resources; If livestock has drunk oily(waste)water, usually fatal esophageal disease can be infected; If use oily(waste)water irrigated farmland, oil content and derivative thereof by the surface of mulching soil and plant, the hole of blocking soil, air is stoped to penetrate, make fruit have oily taste, or make soil normally can not carry out metabolism and bacteria metabolism, time serious, crop production reduction or death can be caused.In addition, due to drift and the diffusion of oil spilling, seabeach and seaside touring areas can be fallen into disuse, cause great environmental hazard and social danger.But main harm is containing carcinogenic hydrocarbon in oil, by fish, shellfish enrichment being detrimental to health by food chain.Therefore, it is extremely necessary that the oily(waste)water produced the industry such as oil and petrochemical industry carries out effectively process.
Current oily water separation technique is more, and conventional method has the technology such as gravitational separation process, air flotation, coalescence, filtration method, absorption method, supersonic method.
Oiliness sewage treatment equipment making is in the market accurate, expensive, be applicable to oleaginousness lower than certain density oiliness sewage treatment, if oil concentration is too high in waste water, the filter core of such treatment facility can be easy to blocking, and cannot process after the blocking of oil suction class filter core, the filter core that can only more renew, this adds increased the working service cost of oiliness sewage treatment equipment.
Summary of the invention
In order to solve above technical problem, the invention provides a kind of oily-water seperating equipment and separation method, apparatus structure is simple, and cost is low, practical, easy to operate, maintenance cost is cheap.
Solve a kind of oily-water seperating equipment in the present invention of above technical problem, comprise waste oil tank body and water pump, it is characterized in that: described device is provided with waste oil water and enters pipe, rising pipe, oil outlet pipe, filter disc and dividing plate, waste oil water enters pipe and enters bend pipe by the oil-feed mouth of a river and waste oil water and form, on the waste oil water tank sidewall that the oil-feed mouth of a river is located at, near dirty oil tank top, waste oil water enters bend pipe and is connected with the oil-feed mouth of a river, in waste oil water tank and downward-extension; Rising pipe is made up of water outlet, Discharging bent-tube, and water outlet is located to enter with waste oil water manages relative waste oil water tank sidewall bottom, and Discharging bent-tube is connected with water outlet, outside waste oil water tank and upper extension; Oil outlet pipe is made up of oil outlet, fuel-displaced bend pipe and switch-valve, oil outlet is located on the dirty oil tank sidewall with rising pipe the same side, near waste oil water box top, higher than Discharging bent-tube vertex, what ensure to flow out in oil outlet is the oil of waste oil water tank water surface top, instead of water.Dividing plate is located to enter with waste oil water manages on adjacent waste oil water tank two side, does not fit respectively, leave gap with waste oil water tank bottom surface and waste oil water tank top cover; Filter disc is located in waste oil water tank, water outlet.
The top cover of described waste oil water tank is movable.
Described top cover is provided with suspension ring, in order to be easy to open top cover, removes the oil on tank inner wall.
Described Discharging bent-tube height is waste oil tank height 3/5-1, and optimum is 4/5.Namely such height does not just affect the gathering of waste oil at top, the maximum volume that make use of waste oil water tank yet.
Described waste oil water tank Plate Welding squarely forms.
Described filter disc is that oil absorbency material is made, and has adsorptivity to oil, and water can be allowed again through filter disc filter pore 25-35 order.
Described dividing plate is connected on relative two side completely, does not fit respectively, leave gap with waste oil water tank bottom surface and waste oil water tank top cover.In order to allow water and oil have time enough to lean on the difference of density and natural separation, add the time that buffering dividing plate separates to extend waste oil water tank water-filled time and oil droplet with water.If dividing plate and bottom surface apart from too far away, profit come in after major part directly directly can flow to water outlet from the gap of dividing plate and bottom surface, the time of profit natural layering can shorten.Dividing plate is better the closer to bottom surface, but can not fit.Dividing plate and top cover apart from too far away, also there is the problem that above-mentioned profit separation time is short.The distance of dividing plate and top cover is also as far as possible close, but the oil that this distance can not affect on the right side of dividing plate flows out smoothly from oil outlet.
Pumping forces size will match with the volume of waste oil water tank, and the time of the enough oily water separation of speed of water tank made by water pump within half an hour.
In the present invention, after oily(waste)water is passed into waste oil water tank, under buffering dividing plate and action of gravity, the oil in oily(waste)water floats up on liquid level, and water then flow to outside by water outlet, and the oil floated on liquid level is flowed out by oil outlet pipe.Meanwhile, regularly can open waste oil water tank top cover and change filter disc, cleaning waste oil water chamber interior wall.
Method during use comprises following steps:
(1) waste oil water pumps into waste oil water by water pump and enters pipe, enters side in waste oil water tank;
(2) waste oil water entering side in dirty oil tank enters dirty oil tank opposite side through the space of dividing plate and dirty oil tank bottom surface and top cover;
(3) water flows out through rising pipe, and waste oil sticks on dirty oil tank inwall or floats on the surface formation waste oil layer of water;
(4) stop pumping into waste oil water, open fuel-displaced switch-valve, release waste oil; Or regularly open waste oil water tank top cover, remove the waste oil on dirty oil tank inner side-wall;
(5) regularly filter disc cleaned or change.
Apparatus structure in the present invention is simple, and cost is low, practical, easy to operate, maintenance cost is cheap.
The present invention is applicable to and produces the factory of oily(waste)water and workshop uses as elementary oil-containing waste water treating device.
All features disclosed in this specification sheets, or the step in disclosed all methods or process, except mutually exclusive feature and/or step, all can combine by any way.
Arbitrary feature disclosed in this specification sheets (comprising any accessory claim, summary), unless specifically stated otherwise, all can be replaced by other equivalences or the alternative features with similar object.That is, unless specifically stated otherwise, each feature is an example in a series of equivalence or similar characteristics.
