[0007] Through the above scheme, by the setting of the ultrasonic vibrator and the emulsifier, the mechanical vibration and thermal effect are generated when the ultrasonic vibrator acts on the oil-water mixture, the mechanical vibration of the ultrasonic vibrator not only makes the water particles move to the node direction of the ultrasonic wave and gather, and generates water droplets with a larger diameter after collision, but also makes the added emulsifier uniformly dispersed in the oil-water mixture, thereby increasing the solubility of the emulsifier, and after the emulsifier is added and dissolved, the oil-water mixture is emulsified, at this time, the mechanical vibration of the ultrasonic vibrator can make the emulsified oil-water mixture uniformly dispersed, increase the solubility, and reduce the mechanical degree of the oil-water interface film, which is beneficial to the water phase separation;

[0028] The above solution has the following advantages:
[0029] 1. By using an ultrasonic transducer and emulsifier, the ultrasonic transducer acts on the oil-water mixture to generate mechanical vibration and thermal effects. The mechanical vibration of the ultrasonic transducer not only causes water particles to shift in the direction of the ultrasonic nodes, causing the water particles to move and gather in the direction of the nodes and generate larger water droplets after collision, but also makes the added emulsifier evenly dispersed in the oil-water mixture, thereby increasing the solubility of the emulsifier. After the emulsifier is added and dissolved, it will emulsify the oil and water. At this time, the mechanical vibration of the ultrasonic transducer can make the emulsifier in the emulsified oil-water mixture evenly dispersed, increase its solubility, reduce the mechanical degree of the oil-water interface film, and facilitate the sedimentation and separation of the aqueous phase.
[0030] By introducing a heat-conducting liquid into the partition between the first and second reactors, the oil-water mixture and the emulsified oil-water mixture in the first reactor are heated. This reduces the strength and viscosity of the oil-water interface film. On the one hand, boundary friction can raise the temperature at the oil-water interface, which is conducive to the rupture of the interface film. On the other hand, the waste oil absorbs some of the heat energy converted by ultrasound, which can effectively reduce the viscosity of the waste oil and facilitate the gravity sedimentation and separation of water particles, thereby achieving complete separation of oil and water and reducing costs.
[0031] 2. By setting the fifth to sixth control valves, the inflow and outflow rate of the heat transfer fluid can be precisely adjusted to avoid over-transfer, thereby saving energy and reducing cost.
[0032] 3. By setting the first to fourth control valves, the inlet and outlet flow rates and velocity before and after oil-water separation can be precisely adjusted to avoid over-transportation, thereby saving energy and reducing cost.
[0033] 4. By setting the seventh control valve, the inlet flow rate and velocity of the catalyst can be precisely adjusted to avoid over-delivery, thereby saving energy and reducing cost.
[0034] 5. By setting up multiple support components, the separation vessel can be supported, thereby ensuring the stability of the separation vessel and ensuring safety during the oil-water separation process;
[0035] 6. By selecting heat transfer oil as the heat transfer fluid, the high thermal conductivity of the oil allows for rapid and efficient heat transfer to the first reactor, thereby accelerating the heating rate of the oil-water mixture within the reactor and improving the separation rate. Furthermore, the heat transfer oil is typically used under low-pressure conditions, which reduces the overall safety risks of the device and enhances the safety of the oil-water separation process. In addition, the heat transfer oil has advantages such as low volatility and low or non-toxicity, resulting in minimal evaporation loss during use and the absence of harmful gases, thus minimizing its environmental impact.
[0036] 7. By setting the limit frame, the storage box can be supported and limited, thereby ensuring the stability of the storage box during the oil-water separation process. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0048] In a specific embodiment, such as Figures 1-8 As shown, the ultrasonic thermal decomposition oil-water separation equipment includes a support base 1, a separation vessel 2 and a storage tank 3 disposed on the support base 1. The storage tank 3 is disposed on one side of the separation vessel 2. The separation vessel 2 includes a first reaction vessel 201 and a second reaction vessel 202 that are double-layered. The first reaction vessel 201 is disposed inside the second reaction vessel 202. An ultrasonic transducer 4 is disposed inside the first reaction vessel 201. The storage tank 3 forms a circuit with the first reaction vessel 201 through a pipe. A catalytic mechanism and a heating mechanism are disposed on the support base 1 on the other side of the separation vessel 2. The catalytic mechanism is connected to the first reaction vessel 201 through a pipe. The catalytic mechanism is used to deliver an emulsifier for catalytic oil-water separation to the first reaction vessel 201. The heating mechanism forms a circuit with the gap between the first reaction vessel 201 and the second reaction vessel 202 through a pipe. The heating mechanism is used to deliver a heat-conducting liquid into the gap between the first reaction vessel 201 and the second reaction vessel 202.

After the emulsifier is added and dissolved, it will emulsify the oil and water. At this time, the mechanical vibration of the ultrasonic transducer 4 can make the emulsifier in the emulsified oil-water mixture evenly dispersed, increase its solubility, reduce the mechanical degree of the oil-water interface film, and facilitate the sedimentation and separation of the aqueous phase.
[0050] The high-temperature heat transfer fluid can heat the oil-water mixture and the emulsified oil-water mixture in the first reaction vessel 201. At this time, the strength and viscosity of the oil-water interface film can be reduced. On the one hand, the boundary friction can increase the temperature at the oil-water interface, which is conducive to the rupture of the interface film. On the other hand, the waste oil absorbs part of the heat energy converted by ultrasound, which can effectively reduce the viscosity of the waste oil and facilitate the gravity sedimentation and separation of water particles, thereby achieving complete separation of oil and water and reducing costs.

The other end of the first inlet pipe 8 and the other end of the heat transfer fluid outlet pipe 7 are connected by a flange. The other end of the first outlet pipe 9 and the other end of the heat transfer fluid inlet pipe 6 are connected by a flange.
[0052] A fifth control valve 10 is installed on the heat transfer fluid outlet pipe 7, and a sixth control valve 11 is installed on the heat transfer fluid inlet pipe 6.
[0053] By setting the fifth control valve 10 to the sixth control valve 11, the inflow and outflow rate of the heat transfer fluid can be precisely adjusted to avoid over-transfer, thereby saving energy and reducing cost.

A circulation pump 16 is provided on the third liquid inlet pipe 15, and a mixed liquid discharge pipe 17 is connected to the third liquid inlet pipe 15.
[0055] like Figure 1 andFigure 8 As shown, the top and bottom of the first reactor 201 are respectively connected to the second feed pipe 18 and the second discharge pipe 19. The other end of the second feed pipe 18 is connected to the other end of the mixed liquid discharge pipe 17 by a flange, and the other end of the second discharge pipe 19 is connected to the other end of the mixed liquid feed pipe 14 by a flange.
[0056] like Figure 3 As shown, a first control valve 20 is installed on the first liquid inlet pipe 12, a second control valve 21 is installed on the second liquid inlet pipe 13, a third control valve 22 is installed on the third liquid inlet pipe 15, and a fourth control valve 23 is installed on the mixed liquid inlet pipe 14. By setting the first control valve 20 to the fourth control valve 23, the inlet and outlet flow rates and velocity before and after oil-water separation can be precisely adjusted to avoid over-transportation, thereby saving energy and reducing cost.
[0057] like Figure 5 As shown, the catalytic mechanism includes a catalytic tank 24 and an emulsifier transfer pipe 25 connected together. The catalytic tank 24 is set on the corresponding support base 1 between the heating tank 5 and the separation vessel 2. In this specific embodiment, a dosing pump is installed on the section of the emulsifier transfer pipe 25 near the catalytic tank 24, which is used to transport the catalyst in the catalytic tank 24 to the first reaction vessel 201 through the emulsifier transfer pipe 25. The catalytic tank 24 is provided with a first liquid inlet, which is used to deliver emulsifier into the catalytic tank 24. The specific emulsifier can be manually selected according to the composition of the specific oil-water mixture before the oil-water separation operation.
[0058] The top of the first reactor 201 is connected to a third feed pipe 27 and a third discharge pipe 28 at intervals.

The emulsifier transmission pipe 25 is equipped with a seventh control valve 29. The seventh control valve 29 can precisely adjust the inlet flow rate and velocity of the catalyst to avoid over-transmission, thereby saving energy and reducing cost.
[0059] A water vapor condensation and adsorption mechanism 26 is provided on the support base 1 on the side of the catalyst box 24 near the separation vessel 2. The air inlet pipe and the third discharge pipe 28 in the water vapor condensation and adsorption mechanism 26 are connected by a flange.

The specific structure and installation method of the water vapor condensation and adsorption mechanism 26 are all existing technologies, which will not be described in detail here. Please refer to the patent application number CN2014203100948.

[0061] like Figure 2 As shown, the heat transfer fluid in the heating box 5 is heat transfer oil. Heat transfer oil has a high thermal conductivity, which enables it to quickly and efficiently transfer heat to the first reactor 201, thereby accelerating the heating rate of the oil-water mixture in the first reactor 201 and thus improving the separation rate. Moreover, the heat transfer oil is usually transported under low-pressure conditions, which can reduce the safety risks of the entire device and thus improve the safety of the oil-water separation process. In addition, heat transfer oil has the advantages of low volatility, low toxicity or non-toxicity, which means that the heat transfer oil has little evaporation loss during use and does not produce harmful gases, thus having a smaller impact on the environment.

This is existing technology and will not be elaborated on here.
[0064] Operating process: The circulating pump is turned on to draw the oil-water mixture in the storage tank. The oil-water mixture enters the first reaction vessel through the first liquid passage pipe, the second liquid passage pipe, the third liquid passage pipe and the mixture discharge pipe.
[0065] The emulsifier in the catalytic box is transported to the first reaction vessel through the emulsifier transfer pipe, where the emulsifier will undergo an emulsification reaction with the oil-water mixture.
