Description

Technical Field

[0001] This utility model relates to the field of oil-water separation technology, and in particular to an ultrasonically enhanced oil-water separation device. Background Technology

[0002] Existing oil-water separation devices mainly rely on gravity sedimentation, chemical flotation, and coalescence separation. While these methods can solve the problem of separating oil from free-state oily wastewater, they are largely ineffective for kitchen wastewater. This is primarily because kitchen wastewater has a high suspended solids content and high viscosity, and the oil and suspended solids in the swill are highly viscous, making it impossible to separate them using conventional methods. Although ultrasound has been used in oil-water separation in some practical applications, it has mainly been used as a pretreatment for conventional oil-water separation or for separating oil-water with simple compositions, and the results have been poor, thus preventing its widespread adoption.

[0003] Based on the characteristics of kitchen wastewater, the problems with existing technologies are summarized as follows: Poor separation effect. Due to the high suspended solids content in kitchen wastewater, and its density being similar to that of water, while most of the swill oil adheres to the suspended solids, conventional sedimentation and vortex methods cannot separate the suspended solids from the water, let alone the swill oil. Although chemical flotation can achieve flocculation and sedimentation of suspended solids, it cannot separate the swill oil from the suspended solids. Poor anti-fouling ability. Existing coalescence separation equipment, although effective for oil-water separation, is prone to fouling, especially since the suspended solids in kitchen wastewater are small, soft, and easily deformable, easily causing irreversible pollution to the coalescence material. Insufficient equipment applicability. Existing ultrasonic equipment mainly treats oily wastewater with a single component, and the equipment type is a simple trough-type ultrasonic container, resulting in poor treatment effect and inability to meet the complex requirements of kitchen wastewater swill oil separation and recycling. Utility Model Content

[0004] The purpose of this invention is to provide a device with oil-water separation function, which solves the problems of difficulty in separating suspended solids from swill oil and difficulty in agglomerating swill oil.

[0005] To achieve the aforementioned objectives, the present invention employs the following technical solution: an ultrasonically enhanced oil-water separation device, comprising: The ultrasonic separation unit has its input end connected to the sewage outlet of kitchen wastewater; The separation chamber is connected to the output end of the ultrasonic separation unit; its inner cavity is equipped with an oil-water separator and a drain pipe is connected to the bottom. The oil collection tank is connected to the top of the separation tank; The stirring mechanism extends from the top of the oil collection tank to the inner cavity of the separation tank; In this process, kitchen wastewater flows into the separation chamber through the ultrasonic separation unit, where it undergoes oil-water separation using an oil-water separator. The swill oil rises with the liquid level into the inner cavity of the oil collection chamber, and the oil and water in the oil collection chamber and the separation chamber are stirred by a stirring mechanism to promote further oil-water separation.

[0006] In some embodiments, the oil-water separator has a plurality of corrugated plates spaced apart along the height direction of the separation chamber; each corrugated plate has an oil port at the crest and a water port at the trough. The upper surface of each corrugated plate is made of stainless steel, nylon, or ceramic, while the lower surface is made of polyethylene, polypropylene, polytetrafluoroethylene, or fiberglass.

[0007] In some embodiments, the ultrasonic separation section includes a tube and a plurality of first ultrasonic oscillators arranged circumferentially along the tube; the vibrator of each first ultrasonic oscillator is in close contact with the outer peripheral wall of the tube, and the vibrating rod of each first ultrasonic oscillator extends into the inner cavity of the tube.

[0008] In some embodiments, the separation chamber and the ultrasonic separation unit are connected by flanges, as are the top of the separation chamber and the oil collection chamber.

[0009] In some embodiments, the tube of the ultrasonic separation section is connected to one side of the oil-water separator.

[0010] In some embodiments, the separation chamber is provided with a plurality of second ultrasonic oscillators located above the oil-water separator. The vibrator of each second ultrasonic oscillator is in close contact with the outer peripheral wall of the separation chamber, and the vibrating rod of each second ultrasonic oscillator extends into the inner cavity of the separation chamber.

[0011] In some embodiments, the stirring mechanism includes: The motor is located above the oil collection tank; The stirring arm is connected at its end to the output shaft of the motor; it extends from the top of the oil collection tank to the inner cavity of the separation tank and passes through the oil-water separator. Multiple agitators are connected to the agitator arm, and the agitators are respectively located in the inner cavity of the oil collection tank, above the oil-water separator, and below the oil-water separator.

[0012] In some embodiments, the lower and upper parts of the sidewall of the separation chamber are respectively provided with a flushing inlet and a flushing outlet, and both the flushing inlet and the flushing outlet are provided with a drain valve; the flushing inlet is connected to a pressure pump. The upper and lower parts of the side wall of the oil collection tank are respectively provided with a first oil outlet and a second oil outlet, and both the first oil outlet and the second oil outlet are provided with an oil drain valve.

[0013] In some embodiments, an oil-water interface gauge is provided on the oil collection tank.

[0014] In some embodiments, the separation chamber is equipped with a pressure level gauge.

[0015] Compared with existing technologies, the beneficial effects of this invention are as follows: This invention uses the ultrasonic action of the ultrasonic separation section to initially separate suspended solids and swill oil, and under ultrasonic action, the swill oil in the ultrasonic separation section undergoes initial aggregation, improving the applicability of the equipment. Subsequently, the kitchen wastewater that has undergone initial oil-water separation in the ultrasonic separation section flows into the oil-water separator. The upper surface of the multiple corrugated plates of the oil-water separator is made of hydrophilic material, and the lower surface is made of oleophilic material. The swill oil in the kitchen wastewater flowing into the oil-water separator will aggregate on the lower surface of the corrugated plates, resulting in poor anti-clogging ability. Furthermore, it rises sequentially through the oil inlet to the inner cavity of the separation chamber and the inner cavity of the oil collection chamber, solving the problem of poor separation effect.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. Of course, the specific embodiments described herein are only for explaining this utility model and are not intended to limit it.

[0021] Before introducing the ultrasonic-enhanced oil-water separation device provided in the embodiments of this application, the following terms will be explained: Kitchen wastewater: After kitchen waste has undergone pretreatment processes such as crushing, screening, and cooking, the wastewater remaining after the free swill oil and solid residue have been removed by a three-phase centrifuge is called kitchen wastewater. Oils: The animal and vegetable swill oil remaining in kitchen wastewater, also known as swill oil, mainly comes from the swill oil added during people's daily cooking and the swill oil produced by the food itself; Ultrasound: Ultrasound refers to sound waves with a frequency higher than 20,000 Hz. It is a mechanical longitudinal wave that propagates in an elastic medium and has characteristics such as good directionality, high energy, and strong penetrating power during propagation.

[0022] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of the ultrasonic enhanced oil-water separation device provided in the embodiment of this application. The ultrasonic enhanced oil-water separation device includes: an ultrasonic separation section 1, a separation chamber 2, an oil collection chamber 3, and a stirring mechanism 4.

[0023] The ultrasonic separation unit 1 may include a tube body 11 and a plurality of first ultrasonic oscillators 12 arranged circumferentially along the tube body 11. Each first ultrasonic oscillator 12 includes an oscillator and a vibrating rod connected to the oscillator. The oscillators of the first ultrasonic oscillators 12 are in close contact with the outer peripheral wall of the tube body 11. When the oscillator vibrates, it can drive the entire tube body to vibrate, thereby improving the efficiency of separating swill oil from suspended solids. The vibrating rod of each first ultrasonic oscillator 12 extends into the inner cavity of the tube body 11. Furthermore, the input end of the tube body 11 of the ultrasonic separation unit 1 is used to connect to the sewage outlet of the kitchen wastewater. The plurality of first ultrasonic oscillators 12 arranged circumferentially along the tube body 11 avoids uneven vibration in unilateral ultrasonic treatment, achieves uniform irradiation of the kitchen wastewater from all directions, accelerates the separation of floating solids from swill oil, promotes the polymerization of swill oil in the tube body 11, and improves the pretreatment efficiency.

[0024] The inner cavity of the separation chamber 2 can be divided into an upper chamber, a middle chamber, and a lower chamber from top to bottom. An oil-water separator 21 is installed within the inner cavity of the separation chamber 2, and is located slightly below the middle chamber. An inlet is provided at the lower part of the middle chamber of the separation chamber 2, and the output end of the ultrasonic separation unit 1 is connected to the inlet of the separation chamber 2. The bottom of the lower chamber of the separation chamber 2 is connected to an external drain pipe 22 and is equipped with a drain valve for discharging wastewater after oil-water separation.

[0025] In some embodiments, the tube 11 of the ultrasonic separation unit 1 is connected to the oil-water separator 21 inside the separation chamber 2. That is, the kitchen wastewater flowing out of the ultrasonic separation unit 1 flows directly into the oil-water separator 21, ensuring that the swill oil after ultrasonic pretreatment is in the most easily aggregated "active" state and can immediately enter the oil-water separator 21 for separation. This avoids energy attenuation and state recovery in the intermediate stage, so that the effect of ultrasonic pretreatment is utilized to the maximum extent and the efficiency and continuity of the entire separation process are guaranteed.

[0026] Please see Figure 1 and Figure 2 , Figure 2 This is a schematic diagram of the structure of the oil-water separator 21 provided in an embodiment of this application. In some embodiments, the oil-water separator 21 may have multiple corrugated plates 211 spaced apart along the height direction of the separation chamber 2; each corrugated plate 211 has an oil outlet 212 at its crest and a water outlet 213 at its trough. The upper surface of each corrugated plate 211 is made of a hydrophilic material, such as stainless steel, nylon, or ceramic, and the lower surface is made of an oleophilic material, such as polyethylene, polypropylene, polytetrafluoroethylene, or glass fiber. Specifically, kitchen wastewater flowing into the oil-water separator 21 from the ultrasonic separation section 1 flows into the gap between two adjacent corrugated plates 211. Because the lower surface of the corrugated plate 211 is made of an oleophilic material, the kitchen waste oil will aggregate on the lower surface of the corrugated plate 211 and form large oil droplets. Under the action of buoyancy, the aggregated large oil droplets rise through the oil outlet 212 until they rise into the oil collection chamber 3.

[0027] The corrugated plate 211 structure extends the flow path of the oil-water mixture, providing a longer processing time for oil-water separation. Oil outlets 212 are located in the oil coalescing zone at the crest, and water outlets 213 in the water coalescing zone at the trough. This cleverly follows the natural tendency of oil to rise and water to flow downwards, providing dedicated, low-resistance outflow channels for oil and water and avoiding mutual interference. Furthermore, the upper surface uses a material with low oleophilicity (the smooth surface of stainless steel, the low-adhesion surface of nylon and ceramic), which facilitates the separation and floating of swill oil; the lower surface uses a highly hydrophobic polymer material, which effectively "repels" water flow, promoting the rapid downward flow of the water phase through the outlet. This dual effect of "material-oriented" and "structure-oriented" design improves coalescence and separation efficiency. The top of the oil collecting tank 3 is connected to the top of the separation tank 2, meaning the top of the upper compartment of the oil collecting tank 3 is connected to the top of the upper compartment of the separation tank 2. In some examples, the inlet of the separation tank 2 is connected to the pipe body 11 of the ultrasonic separation unit 1, and the top of the separation tank 2 is connected to the oil collecting tank 3 via flanges 5. Flange connection is a standardized, detachable connection method. This design allows the ultrasonic separation unit 1, separation tank 2, and oil collecting tank 3 to be modularly produced and transported, enabling rapid on-site assembly. More importantly, after the equipment has been running for a period of time, the ultrasonic separation unit 1 or the oil collecting tank 3 can be disassembled separately for cleaning and maintenance, reducing long-term operation and maintenance costs and extending the equipment's lifespan.

[0028] The stirring mechanism 4 includes a motor 41, a stirring arm 42, and multiple stirring blades 43. The motor 41 is located above the oil collection tank 3. The top of the stirring arm 42 is connected to the output shaft of the motor 41; it extends from the top of the oil collection tank 3 to the inner cavity of the separation tank 2 and passes through the oil-water separator 21. Multiple stirring blades 43 are connected to the stirring arm 42. The multiple stirring blades 43 may include a first stirring blade, a second stirring blade, and a third stirring blade. The first stirring blade is located in the inner cavity of the oil collection tank 3, the second stirring blade is located above the oil-water separator 21, and the third stirring blade is located below the oil-water separator 21. Precise stirring in zones, multi-functional: This design enables the use of a single drive system to complete the stirring tasks of three different functional areas. The stirring blades 43 in the oil collection tank 3: gently stir the collected swill oil to prevent it from cooling and solidifying or stratifying, facilitating subsequent discharge and recycling. The stirring blades 43 above the oil-water separator 21: promote the collision and aggregation of small oil droplets, accelerating their rising speed. The stirring paddle 43 below the separator 21 agitates the lower water layer, preventing solid particles from settling and re-lifting any oil droplets that might sink, giving them a chance to float and separate. Simplified structure, achieving both cost and reliability: Compared to setting up separate motors and stirrers for each zone, this integrated design significantly simplifies the structure, reduces manufacturing costs and equipment failure rates, while ensuring the synchronicity and coordination of stirring actions in each zone.

[0029] In this embodiment, kitchen wastewater flows into separation chamber 2 via ultrasonic separation unit 1. Oil-water separation is achieved through oil-water separator 21. The oil from the swill coalesces and rises with the liquid level to the inner cavity of oil collection chamber 3. A stirring mechanism 4 agitates the oil and water in oil collection chamber 3 and separation chamber 2 to further promote oil-water separation. The cavitation effect of ultrasound shakes oil droplets adhering to floating objects off the floating objects and coalesces the oil droplets, creating favorable conditions for subsequent separation. The oil-water separator 21 in separation chamber 2 further coalesces the oil droplets, causing them to float. Finally, the introduction of the stirring mechanism 4 further promotes the collision and coalescence of oil droplets through mechanical force, preventing blockage of the oil-water separator 21, and performing final fine separation in oil collection chamber 3, improving the purity of the recovered oil and the degree of water purification. The process is integrated and compact: pretreatment, main separation, and oil collection are integrated into one device, realizing continuous operation of swill oil separation and recovery from kitchen wastewater, reducing floor space and equipment investment, and improving the automation level of the treatment process.

[0030] In some embodiments, the separation chamber 2 is equipped with multiple second ultrasonic oscillators 23. Each second ultrasonic oscillator 23 includes an oscillator and a vibrating rod (the vibrating rod can be of different lengths depending on the actual situation). The oscillator of each second ultrasonic oscillator 23 is in close contact with the outer peripheral wall of the separation chamber 2, and the vibrating rod of each second ultrasonic oscillator 23 extends into the inner cavity of the separation chamber 2. All the second ultrasonic oscillators 23 are positioned above the oil-water separator 21. Above the oil-water separator 21, a large number of oil droplets have already accumulated, but there may still be stubborn oil that is difficult to separate. The ultrasonic waves here can "double-blow" these oil-rich areas, achieving deep oil agitation and ensuring complete oil-water separation. At the same time, the intense vibration generated by the ultrasonic waves can effectively clean the surface of the separator and the chamber wall, preventing the adhesion of oil and impurities, and ensuring the long-term stable working efficiency of the oil-water separator 21.

[0031] In some embodiments, the oil collection tank 3 is equipped with an oil-water interface gauge 31 (the oil-water interface gauge 31 is mature prior art and will not be described in detail here). The oil-water interface gauge 31 can monitor the interface position between the oil layer and the water layer in the oil collection tank in real time. Based on this, the opening and closing of the oil drain valve can be precisely controlled to ensure that only high-purity oil is discharged and no water is accidentally discharged. This is a key sensor for realizing fully automatic operation of the device, avoiding the inaccuracy of manual judgment and the risk of oil spill.

[0032] In some embodiments, the separation chamber 2 is equipped with a pressure level gauge 24 (the pressure level gauge 24 is a mature prior art and will not be described in detail here), and the pressure level gauge 24 is located in the lower chamber of the separation chamber 2. The pressure level gauge 24 can monitor the liquid level in the separation chamber 2 to prevent overflow or cavitation, and can also indirectly reflect the system pressure, providing an important guarantee for the stable and safe operation of the equipment.

[0033] In some embodiments, the separation chamber 2 has a flushing inlet 25 at the bottom and a flushing outlet 26 at the top, both equipped with water valves. The flushing inlet 25 is connected to a pressure pump. This allows for a continuous circulating flushing loop through an external pressurized water source and dedicated inlet and outlet, without requiring disassembly of the equipment. Upon entering, the pressurized water first impacts and penetrates the oil-water separator 21, the core component most prone to oil adhesion and impurity blockage. The powerful water flow disperses the accumulated oil and food residue on the corrugated plate 211, restoring its separation efficiency. Furthermore, as the water rises, it naturally impacts and scrapes the inner wall of the separation chamber 2, removing attached oil. This "one-way in, one-way out" flow pattern ensures that the flushed oil and impurities are immediately carried away by the water flow, preventing secondary deposition and improving cleaning efficiency. Operators only need to remotely control the valve switches and start the pressurized water pump, eliminating the need to open the chamber for dangerous manual cleaning, thus achieving timed and periodic automatic cleaning.

[0034] The design of the flushing inlet 25 and flushing outlet 26 transforms a tedious and passive maintenance task into an efficient and proactive process optimization step. The resulting online cleaning capability, comprehensive cleaning effect, potential for operational automation, and long-term cost savings collectively ensure that the entire ultrasonic enhanced oil-water separator can operate stably, reliably, and with low maintenance as a high-performance industrial-grade device for extended periods.

[0035] In some embodiments, the oil collection tank 3 has a first oil outlet 32 ​​at the top and a second oil outlet 33 at the bottom, and both the first oil outlet 32 ​​and the second oil outlet 33 are equipped with oil discharge valves. After the swill oil has completely collected in the oil collection tank 3 under buoyancy, production line workers can first open the second oil outlet 33 to observe the purity of the swill oil in the lower part of the inner cavity of the oil collection tank 3. If the purity of the swill oil discharged from the second oil outlet 33 meets the recycling standards, the second oil outlet 33 is opened to discharge the swill oil in the oil collection tank 3, which can then be used as raw material for biodiesel production or high-value chemical raw materials. If the purity of the swill oil discharged from the second oil outlet 33 does not meet the recycling standards, the first oil outlet 32 ​​is opened to discharge the waste oil in the upper part of the oil collection tank 3. It should be noted that, since the first oil outlet 32 ​​is located at the top of the oil collection tank 3, the lighter oil (i.e., oil with few or no impurities) will float to the top layer due to buoyancy. The oil collected at the top of the first outlet 32 ​​is the "premium swill oil" with the highest purity and fewest impurities. This type of oil is of the best quality and has a high qualification rate for producing biodiesel or high-value chemical raw materials. Furthermore, both oil outlets are equipped with independent drain valves, allowing operators to flexibly decide to open either valve based on the reading of the oil-water interface gauge 31, thus improving operational efficiency.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
