Example

[0034] See also Figure 1-7 A continuous separation device for a light and heavy phase mixture comprises a device base 1 and a separator 101. The separator 101 is installed on the device base 1. A hazardous waste liquid inlet 2, a first outlet 201, an oil phase outlet 202 and a second outlet 3 for continuous separation are respectively arranged on one side of the separator 101. A storage tank 302 is installed on the top of the separator 101 to reduce odor emission.

[0035] Some implementation methods of the present application are described in detail below with reference to the accompanying drawings:

[0036] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 The continuous separation device of the light and heavy phase mixture of the present application is combined with the device base 1 and the separator 101. The second outlet 3 is vertically connected to one side of the device base 1 by setting the second outlet 3, and the hazardous waste liquid inlet 2, the first outlet 201 and the oil phase outlet 202 are vertically connected to the other side of the separator 101. From top to bottom, the oil phase outlet 202, the hazardous waste liquid inlet 2 to the first outlet 201 are distributed, and the hazardous waste liquid inlet 2 is located between the oil phase outlet 202 and the first outlet 201. The two immiscible liquids are continuously separated. At the same time, during the continuous separation, the storage tank 302 is installed on the top of the device to seal the required nitrogen sealing gas and waste oil to reduce and prevent the odor from being emitted into the atmospheric environment. At the same time, it has the function of preventing the separator from being over-pressurized or negatively pumped, ensuring the safe use of the container, thereby achieving the purpose of separating the two-phase liquid entering the separator 101.

[0037] In a specific implementation, first, the hazardous waste liquid inlet 2 should be near the interface of the two liquid phases that need to be separated in the separator 101, through the second outlet 3, which is the water phase and heavy phase outlet side, and the first outlet 201 is designed to be a drain port or a liquid level meter connection port, and is regulated by the interface regulating valve group 301 arranged on the outlet side of the second outlet 3.

[0038] The hazardous waste liquid inlet 2 adopts a pump-in connection method, so that after the mixed hazardous waste enters the interior, the stratified oil phase and water phase can be discharged due to the increase in the amount of liquid in the separator 101, wherein the upper oil phase and the lower water phase are discharged at the upper part through their respective overflow ports, namely the first outlet 201 and the second outlet 3, respectively, and the newly entered liquid hazardous waste is separated in the separator 101. Since the residence time of the liquid hazardous waste entering the separator 101 in the separator 101 is much greater than the two-phase liquid separation time, the purpose of separating the two-phase liquid entering the separator 101 is achieved.

[0039] In some embodiments, since each time the hazardous waste solution newly enters the device base 1, it needs to reach the oil phase outlet 202 or the upper part of the second outlet 3 for discharge after separation, if a certain distance is designed between the first outlet 201 and the second outlet 3 and the device base 1 for the solution after the last separation to stay, when the hazardous waste solution repeatedly enters the separation, each time the new solution entering from the hazardous waste liquid inlet 2 can be discharged higher than the oil phase outlet 202 or the upper part of the second outlet 3. During continuous separation, since the solution that stayed last time has been separated, the newly entering liquid hazardous waste is allowed to merge with the solution that stayed at the bottom of the device base 1 last time after separation before the next separation. Repeating this process can improve the quality of the discharge after continuous separation and make the separation more thorough.

[0040] See also Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 In the present application, a guide tube 4 and an interface 401 are also provided, wherein the guide tube 4 is opened on one side of the bottom of the device base 1, and the interface 401 is threadedly connected to the inside of the interface 401, and its downward sloped design allows the catheter to be connected to bring out the mixed solution with impurities at the bottom through the guide tube 4 when impurities and mixed solution are deposited at the bottom of the subsequent device base 1, and at the same time, the water pipe is connected for direct flushing, which is convenient for discharge operation.

[0041] A limiting ring 404 and a first sealing ring 405 are also provided in the present application. When the guide tube 4 is connected to the inside of the interface 401, the limiting ring 404 is installed on the outer ring of the guide tube 4. After the limiting ring 404 is driven to contact the bottom of the device base 1, the guide tube 4 is limited. At the same time, a first sealing ring 405 is provided on the side of the limiting ring 404 that contacts the bottom of the device base 1. After the first sealing ring 405 is pressed into the card groove at the bottom of the device base 1, the sealing of the connection is improved.

[0042] The present application also provides a cover 402 for connecting to the outlet of the guide tube 4 when not in use, wherein the installation sleeve 406 is provided with an internal thread matching the outer ring of the outlet of the guide tube 4, and the cover 402 is docked at the outlet of the guide tube 4 so that the installation sleeve 406 is threadedly connected to the guide tube 4 to complete the connection between the two, which is also convenient for subsequent disassembly; at the same time, when the installation sleeve 406 is sleeved on the outside of the outlet of the guide tube 4, a second sealing ring 407 that can be pressed on the guide tube 4 is provided at its inner ring to improve the sealing of the connection between the two.

[0043] See also Figure 4 , Figure 6 and Figure 7 In the present application, an internal impurity cylinder 403 is also provided and installed inside the cover 402. When the cover 402 is installed, the internal impurity cylinder 403 is located at the discharge outlet of the guide tube 4, facing downward. In this way, during long-term use, the sediment can be screened out and directly sink from the opening of the guide tube 4 to the inside of the internal impurity cylinder 403 for separation and treatment from the guide tube 4.
