Description
Affiliated technical field
The utility model relates to a kind of chemical separating equipment, is the coagulation type liquid liquid/gas separator that a kind of immiscible liquid that is used for, especially liquefied ammonia and compressor oil separate.
Background technology
The ammonia finished product can be with generating products such as urea, carbon ammonia and nylon salt.Different subsequent products has various requirement to the purity of ammonia, and one of decisive factor is the content of oil in the ammonia.Oil removing has two kinds of ways basically in ammonia, and one is in synthetic ammonia process, and unstripped gas does not carry out oil removing earlier before advancing synthetic tower, and two carry out liquefied ammonia branch oil after generating product liquefied ammonia.The former way equipment blocks easily, needs often to clean, and stops.Latter's correlation technique situation is as follows:
Adopt that deoiling method is a settling methods in the more liquid.Sedimentation time, each factory's difference was bigger, and short is about 40 hours, and long is about 736 hours, and remaining was at 50～70 hours.The jar number is provided with more than two or two usually.First is settling tank, and second is surge tank, two jars of serial operations, and the oil in the settling tank can flow to slop tank certainly by the oil drain out of tank skin.According to the test of oil content in the water with the sedimentation time variation, sedimentation time was greater than 35 hours, oil concentration can drop to below the 100mg/L (not containing oil emulsion, dissolved oil) in the water, be to keep the stable of sedimentation tank level, being unlikely is back to back because of water causes stirring, so that influences effect of settling, member in umbrella stand formula or the Tray type is set in jar, because of jar hold and floor space all very big, and jar in oil slick easily collecting not, the de-oiling effect is difficult to assurance.
The separator that often has in addition, suspension type liquid liquid/gas separator for example utilizes the rotation of power drive impeller, makes the two-phase rotation, and the solid sundries that proportion is bigger is sunk fast, and proportion is lighter bubbles through the water column mutually and realizes separating.This apparatus structure complexity needs power, takes the energy, is used for the king-sized occasion of wastewater flow rate more.
This is tested novel coalescing medium and utilizes the hydrophilic and oleophilic material, its surface area is big, big with oil surface tension, make oil droplet stay on the medium, increased the probability that oil droplet is captured, oil droplet carries out coalescent, pass through Gravity Separation then, the more board-like coarse separation device of efficient is higher, and processing accuracy is higher, can handle the extremely low or high concentration that traditional liquid liquid/gas separator can not be handled, in addition two be separated after, add the mat that is used to absorb absorption remaining residue liquid phase, further purified the separation two-phase, do not needed working power, simple in structure.
Summary of the invention
The most general oily water separation technique is to use simple Gravity Separation.At this moment have at least three kinds of active forces to act on above the oil droplet that will separate.The empirical equation of Stokes sinking speed makes us can calculate the needed time of sedimentation, thus estimation separator needed size, however for the situation of less oil droplet or big flow, can make container excessive, on economic benefit, do not meet.Introduce coalescer this moment can make the container size drop to 1/5th of original size at most.
The separation of coalescer mainly is divided into three steps.At first be the seizure of oil droplet, oil droplet coalescent and then allow oil droplet pass through Gravity Separation.The factor that can have influence on the coalescer effect depends on two aspects, the one, and the characteristic of coalescing medium, the 2nd, the character of logistics.When coalescing medium is a lipophilic material, itself and oil surface tension are bigger, make oil droplet stay on the medium easily, wait for coalescent.When media table area height, also increased oil droplet one and opened the probability that makes seizure.When two liquid phase interface tension force big, density contrast hour, the gravitational settling ability becomes poor, the coalescer effect also can be restricted.When logistics speed greater than laminar flow, then on the one hand gravitational settling is hindered, and oil droplet also can't stay on the medium for a long time, makes that coalescent effect is relatively poor.
This is tested novel coalescing medium and utilizes the hydrophilic and oleophilic material, its surface area is big, big with oil surface tension, make oil droplet stay on the medium, increased the probability that oil droplet is captured, oil droplet carries out coalescent, by Gravity Separation, the more board-like coarse separation device of efficient is higher then, and processing accuracy is higher, can handle the extremely low or high concentration that traditional liquid liquid/gas separator can not be handled, not need working power, simple in structure.Coalescing medium thickness is big, is tens times of filter core internal layer outer layer thickness, structure voidage height, and the life-span is also therefore than filter core height, becomes the optimal components that substitutes the technology that filter core or coalescing-plate can't adapt to.
For remaining separation phase, the oil-wet behavior of the oil of residue in the liquefied ammonia by organic material absorbs and adsorb, makes further purifying of liquefied ammonia, satisfied higher requirement.
The utility model has overcome the prior art deficiency, provide a kind of can be from liquefied ammonia separate compressor oil, do not need working power, simple in structure, separating effect is high, and the liquefied ammonia that can move continuously divides oily device.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: comprise container, be provided with inlet, light phase export, heavy out; The described container rear exit that enters the mouth from the place ahead is provided with inlet, coalescent assembly, oily absorption pad, heavy out, light phase export successively.
Described heavy out, light phase export are connected on the receiving hopper; Described receiving hopper can be up or down; Described coalescent assembly can be the coalescent assembly of braiding and forms or board-like coalescent assembly or the coalescent assembly of material filling type; The coalescent assembly of described braiding can be that stainless steel silk thread braiding forms or glass fibre and the braiding of stainless steel silk thread form; Described oily absorption pad is an organic material; Described organic material is the polyethylene material.
