Abstract

The utility model discloses an oil-water separation device which is characterized by comprising a water inlet pipe, a water outlet pipe, an oil outlet pipe and a closed barrel, wherein the water inlet pipe and the water outlet pipe are respectively inserted into the barrel in a sealed mode; the lower end of the water outlet pipe is close to the bottom of the barrel; a horizontal water outlet is formed in the upper end of the water outlet pipe; the lower end of the oil outlet pipe is fixedly communicated with the barrel; a horizontal oil outlet is formed in the upper end of the oil outlet pipe; when an oil-water mixture in the barrel reaches static balance, the height from an oil-water separation surface in the barrel to the barrel bottom is smaller than the height from a water outlet to the barrel bottom, and the height from the water outlet to the barrel bottom is smaller than the height from the oil outlet to the barrel bottom. The oil-water separation device has the advantages that the principle of a communicating vessel is utilized, a height difference is formed between the water outlet and the oil outlet, and the lower end of the water outlet pipe is close to the bottom of the barrel body, so that water with the purity of 100 percent is discharged from the water outlet pipe, and oil with the purity of 100 percent is discharged from the oil outlet pipe.

Description

A kind of oily-water seperating equipment

Technical field

The utility model relates to a kind of oily-water seperating equipment.

Background technology

Along with industrial fast development, human living standard's progressively raising, environmental problem arouses widespread concern.At present, in the kitchen scouring waste water of catering trade, contain a large amount of greases, directly discharge can cause serious environmental pollution and the waste of resource, and the problems such as corrosion also can result in blockage to discharge of wastewater system.In addition, in oil exploitation process, need to oil be taken out of from underground to underground flooding, exploitation oil water mixture out need to be realized water-oil separating, so that follow-up PETROLEUM PROCESSING.At present, for chemical oil water mixture, generally adopt extraction, or flocculation sediment partition method, not only uneconomical but also not environmental protection, also there will be the problem of secondary pollution; And for the processing of life profit, generally take artificial separation or directly discharge, this or labor intensive, efficiency are low, or waste resource, contaminated environment.Therefore, for how, the efficient high-quality research that separates profit from oil-water mixture is significant.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of efficiently high texture and separates profit and oily-water seperating equipment simple in structure.

The utility model solves the problems of the technologies described above adopted technical scheme: a kind of oily-water seperating equipment, comprise water inlet pipe, outlet pipe, the staving of flowline and sealing, described water inlet pipe and outlet pipe seal respectively and insert in described staving, the lower end of described outlet pipe is near the bottom of described staving, the upper end of described outlet pipe is provided with the delivery port of level, the lower end of described flowline is fixedly communicated with described staving, the upper end of described flowline is provided with the oil-out of level, when the oil water mixture in staving reaches static balancing, water-oil separating face in described staving to the height at the bucket end is less than the height of described delivery port to the bucket end, described delivery port to the height at the bucket end is less than the height of described oil-out to the bucket end.

Described flowline one is connected on the upper surface of described staving.

The internal diameter of described flowline is that lower large gradual change is supreme little.

Compared with prior art, the utility model has the advantages that this device has utilized law of connected vessels, delivery port and oil-out have difference in height, and the lower end of outlet pipe is near the bottom of staving, thereby guaranteed from outlet pipe discharge be the water of 100% purity, from flowline discharge is the oil of 100% purity; Because the internal diameter of flowline is that lower large gradual change is supreme little, the surface area of the critical groundwater table while effectively having increased water-oil separating, has improved the stability of water-oil separating, has guaranteed the high-purity of water-oil separating again; In addition, this apparatus structure is simple, workable, and the market demand and using value are high, can accomplish scale production.

Fig. 2 is cutaway view of the present utility model;

Fig. 3 is the principle schematic when the oil water mixture in staving reaches static balancing.

The specific embodiment

Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.

As shown in the figure, a kind of oily-water seperating equipment, comprise water inlet pipe 1, outlet pipe 2, the staving 4 of flowline 3 and sealing, water inlet pipe 1 and outlet pipe 2 seal respectively and insert in staving 4, the lower end of outlet pipe 2 is near the bottom of staving 4, the upper end of outlet pipe 2 is provided with the delivery port 21 of level, the lower end one of flowline 3 is connected on the upper surface of staving 4, the internal diameter of flowline 3 is that lower large gradual change is supreme little, the upper end of flowline 3 is provided with the oil-out 31 of level, when the oil water mixture in staving 4 reaches static balancing (as shown in Figure 3), water-oil separating face in staving 4 is less than delivery port 21 to the height H 1 at the bottom of bucket to the height h1 at the bucket end, delivery port 21 to the height H 1 at the bottom of bucket is less than oil-out 31 to the height H 2 at the bottom of bucket.

In above-described embodiment, the operation principle of this oily-water seperating equipment is: when oil-water mixture is from water inlet pipe 1 enters staving 4, because the density of water is greater than oily density, oil can appear the surface at water in one's mind, under the effect of pressure, water can be by entering outlet pipe 2 at the bottom of bucket, and along with constantly entering of oil-water mixture, the oil-water mixture in staving 4 can constantly increase; From law of connected vessels, when the oil-water mixture in staving 4 reaches static balancing, be that water overflows delivery port 21 just, and oil is when just overflow from oil-out 31, the water-oil separating face on the left side can be all the time lower than water outlet height, can guarantee that thus water can only overflow from the delivery port of outlet pipe 2 21, and oil can only overflow from the oil-out of flowline 3 31, thereby guarantee purity and the quality of water-oil separating.When Chuck Steak in oil-water mixture, the height of water-oil separating face can be less than h1, and then the height of water level in outlet pipe 2 can be less than H1, along with oil takes the lead in constantly discharging from oil-out 31, water is constantly in the interior accumulation of staving 4, the height of water-oil separating face can increase gradually, until reach h1, water starts to overflow from delivery port 21; In like manner, when the water in oil-water mixture is more, the height of the water-oil separating face on the left side can be a little more than h1, along with the continuous accumulation of oil water mixture, water can take the lead in constantly from delivery port 21, overflowing, and oil is constantly in the interior accumulation of flowline 3, until oil overflows from oil-out 31.
