Description
Technical Field
The invention relates to an oil-water separator.
Background
PEX panels were format coalescers developed in the 80 th century by the american company NATCO, some of which were called composite corrugated panels. The corrugated plate provides a tortuous path for fluid to flow over its surface, which maximizes the collection of dispersed droplets. The coalescence plates are vertically installed, the corrugation direction on the plates forms an angle of 30-60 degrees, the corrugation on alternate corrugated plates is parallel to each other, and the corrugation of two adjacent plates is crossed. Thus, the alternating upward and downward movement of the fluid through this portion facilitates the coalescence of the dispersed phase droplets, and such coalescence plates are mainly used for oil-water separation. The cross-flow device has a coalescence part formed by overlapping a plurality of layers of inclined plates, can greatly improve the separation efficiency compared with a single-layer plate coalescer, and is not easy to block. The coalescing section may be made of different materials such as polypropylene, ceramic or stainless steel. But the same point lies in that the oil-water separator can be combined with hydrophobic oil, and the oil drops are carried with the oil to rise, and the rising speed is increased by about thousand times, so that the oil-water separation efficiency is very high. At present, the method is widely applied to oil-water separation of oil fields, treatment of petrochemical wastewater, food oil production wastewater and the like, and is characterized by large volume, and the corrugated plate is statically placed in a large-scale separator.
The present small separator 'a kind of oil-water separation method and equipment-201410852259.9' discloses an oil-water separation method and equipment, in which the corrugated net plate is driven by motor to make it move up and down and rotate so as to make the liquid drops in the emulsion continuously coalesce, and after a certain time, the oil-water separation can be completed. However, the corrugated net plate structure is a continuous curved surface, so that the manufacturing difficulty is high, and the eddy current is easily caused.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The oil-water separation principle of the invention is as follows:
the corrugated plate coalescence oil-water separation technology is a novel oil-water separation technology integrating gravity separation and coalescence separation. The larger the oil droplet size, the higher the removal efficiency, and if the micro oil droplets in water can be combined and coalesced into large oil droplets, the removal efficiency can be significantly improved. The coalescence technology can make the oily sewage pass through the bed layer formed from solid matter whose surface is oleophylic (such as polypropylene, ceramic or stainless steel), and can make the fine oil drops be adhered on the surface of solid bed layer, and gradually accumulate into large oil drops so as to make separation. The limiting conditions of the technology are that the flow rate cannot be too large, a buoyancy lift separation space needs to be additionally arranged, and meanwhile, regular backwashing and the like are also needed, so that the investment and the operation cost are increased. The corrugated plate coalescence oil-water separation technology is based on the principle, and the oil drop separation efficiency is improved by shortening the oil drop floating height by adopting the multilayer corrugated plate group. Meanwhile, in the flowing process of the oil-water mixed phase in the plate group, because the flowing cross section is constantly changed and the corrugated flow channel is flowed, the flowing speed of the fluid is constantly changed, the direction is constantly changed, the probability of oil drop collision coalescence is increased, oil drops are constantly coalesced and enlarged in the moving process, oil films are formed on the upper surface and the lower surface of the corrugated plate through interaction such as wetting, adsorption and coalescence, the oil films move along the plate surface and fall off, the water phase is settled under the action of gravity and reaches the upper surface of the lower corrugated plate, and finally, the separation of oil and water is quickly realized. The fish scale-shaped corrugated net plate designed by the invention can realize up-and-down and rotary motion, small holes on the fish scale can accelerate liquid flow, so that the separation effect is more obvious, relative motion of liquid drops is caused by the rotary motion of the fish scale-shaped corrugated net plate, the liquid drops in emulsion at different heights can be continuously coalesced in the up-and-down motion process of the fish scale-shaped corrugated net plate, and oil and water can be separated after a certain time.
The present embodiment provides an oil-water separator, as shown in fig. 1-4, which includes a hollow central column 1, 2 layers of staggered columns 2 are radially and uniformly distributed on the outer wall of the lower column of the central column 1, each layer is provided with 3 columns 2, and the columns 2 are perpendicular to the central column 1;
each column body 2 is provided with a fish scale-shaped corrugated net plate 3 with a variable angle, each corrugated net plate 3 is provided with a plurality of small holes, and the column body 2 and the corrugated net plate 3 fixed on the column body 2 rotate around the central column 1.
The material of the corrugated mesh plate 3 is a conglomerate material, such as composite polypropylene or ceramic.
The corrugated net plate 3 is a composite polypropylene coalescence plate, the surface free energy and the surface tension of polypropylene molecules are lower due to the nonpolar characteristic of the polypropylene molecules, and the polypropylene coalescence plate is a typical lipophilic material, so that the polypropylene coalescence plate is applied to the oil-water separation industry, in particular to an oil-water separation device with a fish scale-shaped corrugated net plate; the composite polypropylene coalescence plate strengthens the oil-water separation process, increases the oil-water separation effect, and further improves the application potential of polypropylene in the oil-water separation industry. The ceramic plate corrugated coalescence packing is a novel structured packing and has the advantages of high efficiency, small resistance, low price, corrosion resistance, high temperature resistance (500 plus 700 ℃), wide operation range, unobvious amplification effect and the like. Therefore, the method is firstly used in the separation process of high-temperature and corrosive media, and the operating pressure is between 0.1 and 500 KPa. Where large amounts of inorganic acids and alkalis are present, such fillers should not be employed. The ceramic filler has the advantages of blockage resistance, corrosion resistance, friction resistance and the like, and can gradually replace metal and plastic fillers to be widely applied to the crude oil dehydration process, and the actual effect is achieved.
The invention is used in a small vertical separator, controls to carry out compound motion, and leads the separation to be more thorough and rapid through the up-and-down and rotation motion.
The corrugated net plate is placed in the separator, the separated oil and water are discharged from the same outlet of the separator and are respectively collected, and the oil and the water are detected and distinguished by the sensor and controlled by the electromagnetic valve, so that the structure of the separator is further simplified.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and it should be noted that those skilled in the art should make modifications and variations without departing from the principle of the present invention.
