Description

Technical Field

[0001] The utility model belongs to the field of three-phase separation, and in particular relates to a raw material three-phase separator. Background Art

[0002] The main function of the "original three-phase separator" is to process a mixture containing water, oil (or other organic liquids), and solids, and to separate the water, oil, and solids in the mixture from the "three-phase separator" to obtain relatively dry solid particles, oil, and water. Because of its special gas phase, liquid phase, and solid phase separation technology capabilities, it is called a "three-phase" separator. It does not change the basic properties of the original solids and different types of liquids in the mixture at the working temperature, so it can be called a "original three-phase separator."

[0003] CN201611176683.1 discloses an oil-water-solid three-phase centrifugal separation unit, which has a sewage pipe at the bottom of the tank to separate the solid phase; a first solid filter, a drainage valve and a super-hydrophilic membrane filter are provided to separate the water phase; a second solid filter, an oil drain valve and a super-hydrophobic membrane filter are provided to separate the oil phase. The aforementioned public patent uses an unpowered sedimentation method for separation, which is suitable for the case where there are fewer solids in the mixture, but not for the case where there are more solids in the mixture. When there are more solids in the mixture, the solids will block the first solid filter and the second solid filter, and the three-phase separation cannot be achieved. Utility Model Content

[0035] Embodiment 1

[0036] This embodiment provides a three-phase separator. Figure 1 As shown, in a preferred embodiment, it includes a tank body 10 with a feed port 11 at the top, and a gas outlet 12, a liquid outlet 13 and a solid material outlet 14 are also provided on the tank body 10. Preferably, the gas outlet 12 is provided at the top of the tank body 10, and the liquid outlet 13 and the solid material outlet 14 are provided at the bottom of the tank body 10 and are isolated from each other. A heating unit 20 capable of heating the mixture in the tank body 10 is provided in the tank body 10, and the power of the heating unit 20 can be adjusted to change the heating temperature. In the utility model, the heating unit 20 includes an electromagnetic heater or a resistance heating wire arranged outside the tank body 10 or embedded in the side wall of the tank body 10, and an insulation layer is provided outside the electromagnetic heater or the resistance heating wire.

[0037] The tank body 10 is provided with a centrifugal separation unit 30, which separates water and organic solution by rotating. The centrifugal separation unit 30 has one or two separation levels. In this embodiment, two separation levels are arranged at intervals along the height direction of the tank body 10 as an example. The two separation levels are a first separation level 31 located at the top and a second separation level 32 located at the bottom.

[0038] When the original three-phase separator is used, the original mixture of water, organic solution (referring to an organic solution with a density lower than that of water, including oil) and solid enters the first separation level 31 of the tank body 10 through the feed port 11.

[0039] In the first embodiment, the first separation level 31 operates at a first speed, and the heating unit 20 operates at a first temperature state (the first temperature is higher than the boiling point of water and lower than the boiling point of the organic solution, ensuring that the water can be gasified into water vapor and the organic solution will not be gasified). Under the action of centrifugal force, the water with a higher density in the original mixture is thrown out from the first separation level 31 for separation, and the organic solution with a lower density will not be thrown out due to insufficient centrifugal force. Under the action of the heating unit 20, the water is gasified into water vapor and discharged from the gas outlet 12, thereby achieving water separation. Preferably, the gas outlet 12 is connected to a condenser 611 through a pipeline, and the outlet of the condenser 611 is connected to a water storage container 61. The discharged water vapor is reduced to liquid water by the condenser 611 and collected by the water storage container 61.

[0040] The remaining mixture after the water is separated enters the second separation level 32. The second separation level 32 operates at a second speed. The heating unit 20 operates at a second temperature state. The second speed is greater than the first speed to provide a greater centrifugal force. The second temperature is higher than the first temperature. The second temperature is lower than the boiling point of the organic solution to ensure that the organic solution will not vaporize. Under the centrifugal force of the second separation level 32 and the temperature, the organic solution in the remaining mixture tends to separate and is discharged from the liquid outlet 13 to achieve the separation of the organic solution; the remaining solid matter is discharged from the solid material outlet 14 to achieve the separation of the solid matter. Preferably, the liquid outlet 13 is connected to a liquid receiving container 62 for collecting the organic solution, and the solid material outlet 14 is connected to a solid receiving container 63 for collecting the solid matter.

[0041] In the aforementioned embodiment, the first separation level 31 and the second separation level 32 have different operating speeds and different centrifugal forces. In another embodiment, the first separation level 31 and the second separation level 32 have the same operating speed and both operate at the first speed. At this time, the centrifugal force provided at the first speed can drive the liquid (including water and organic solution) to separate, and the separated water splashes onto the inner wall of the tank 10 and is heated to be discharged as water vapor. The separated organic solution flows downward along the inner wall of the tank 10 to the bottom of the tank 10 and is discharged from the liquid outlet 13.

[0042] In addition, the utility model can also be used to separate a mixture of water, grease and solid matter (such as kitchen waste). When the first separation level 31 is rotated and separated, the grease is heated and melted into oil liquid. When the second separation level 32 is rotated and separated, under the action of centrifugal force, the oil liquid is thrown out to separate and discharged from the liquid outlet 13 to the liquid receiving container 62. When the second separation level 32 is rotated and separated, the heating unit 20 may or may not work. When the temperature in the tank body 10 is higher than the melting temperature of the grease, the heating unit 20 may not work. When the temperature in the tank body 10 is lower than the melting temperature of the grease, the heating unit 20 works to ensure that all the grease is melted into oil liquid.

[0043] In a preferred embodiment of the utility model, an annular isolation ring 15 is fixedly connected to the bottom of the tank body 10, and the separated organic solution falls to the bottom of the tank body 10 between the isolation ring 15 and the inner wall of the tank body 10, and the liquid outlet 13 is connected to the bottom area of ​​the tank body 10 between the isolation ring 15 and the inner wall of the tank body 10, and the solid material outlet 14 is connected to the bottom area of ​​the tank body 10 within the isolation ring 15, so that the liquid outlet 13 and the solid material outlet 14 are isolated from each other, and the separated organic solution is separated from the solid matter.

[0044] In the utility model, the first separation level 31 and the second separation level 32 have the same structure, and the side walls of the separation levels are provided with drainage channels for liquid discharge. The drainage channels are narrow, and solid matter cannot be discharged from the drainage channels. Under the action of centrifugal force, the liquid in the original mixture is thrown out from the drainage channel and splashes onto the inner wall of the tank body 10. The thrown out water is heated by the heating unit 20 to be vaporized into water vapor, and the thrown out organic solution splashes onto the inner wall of the tank body 10. Under the drainage action of the inner wall of the tank body 10, the organic solution falls to the bottom of the tank body 10 and is discharged from the liquid outlet 13.

[0045] Specifically, each separation level includes at least one separation rotating disk 301 located in the tank body 10 and arranged at intervals along the height direction of the tank body 10, and a rotation drive mechanism for driving the separation rotating disk 301 to rotate, for example, two separation rotating disks 301 are arranged in one separation level; there is a gap between the outer wall of the separation rotating disk 301 and the inner wall of the tank body 10, and an annular paddle 302 is fixedly connected to the outer periphery of the separation rotating disk 301, and a discharge port is arranged on the separation rotating disk 301, and a discharge valve 303 is arranged at the discharge port. Among them, the first separation level 31 includes the first separation rotating disk 311, the first paddle 312, the first discharge port and the first discharge valve 313, and the second separation level 32 includes the second separation rotating disk 321, the second paddle 322, the second discharge port and the second discharge valve 323.

[0046] The drainage channel is a plurality of vertically extending drainage slits circumferentially spaced on the blade 302; or the blade 302 includes a plurality of circumferentially spaced sub-blades, and the gaps between adjacent sub-blades are the drainage channel. Then the drainage slits on the blade or the gaps between adjacent blades are the channels for discharging the centrifugally separated liquid.

[0047] In one embodiment, two first separation rotating disks 311 are connected in series, and two second separation rotating disks 321 are also connected in series. The original mixture first enters the upper first separation rotating disk 311, and the rotary drive mechanism drives the first separation rotating disk 311 to rotate. Under the action of centrifugal force, most of the water in the original mixture is thrown out to the inner wall of the tank body 10 through the drainage channel on the first paddle 312 for separation; the first discharge valve 313 of the upper first separation rotating disk 311 is opened, and the mixture enters the lower first separation rotating disk 311 for secondary water separation. The mixture after water separation enters the upper second separation rotating disk 321, and the rotary drive mechanism drives the second separation rotating disk 321 to rotate. Under the action of centrifugal force, most of the organic solution in the mixture is thrown out to the inner wall of the tank body 10 through the drainage channel on the second paddle 322 for separation; the second discharge valve 323 of the upper second separation rotating disk 321 is opened, and the mixture enters the lower second separation rotating disk 321 for secondary separation of organic solution.

[0048] In another embodiment, two first separation rotating disks 311 are connected in parallel, and two second separation rotating disks 321 are also connected in parallel. The original mixture first enters the first separation rotating disk 311 of the upper layer, and part of the original mixture enters the first separation rotating disk 311 of the lower layer through the first discharge port of the first separation rotating disk 311 of the upper layer. The two first separation rotating disks 311 rotate simultaneously to separate the water; the mixture after the water is separated enters the second separation rotating disk 321 of the upper layer, and part of the mixture enters the second separation rotating disk 321 of the lower layer through the second discharge port of the second separation rotating disk 321 of the upper layer. The two second separation rotating disks 321 rotate simultaneously to separate the organic solution and improve efficiency.

[0049] In a preferred embodiment of the present invention, the first separation rotating disk 311 and the second separation rotating disk 321 are driven by a set of rotation drive mechanism. Specifically, the rotation drive mechanism includes a rotation motor 40 disposed below the tank body 10, the rotation speed of the rotation motor 40 is adjustable, the output shaft of the rotation motor 40 is coaxially fixed with a central shaft 41 extending into the tank body 10, and the first separation rotating disk 311 and the second separation rotating disk 321 are coaxially fixed on the central shaft 41. Preferably, the central shaft 41 is arranged from the bottom of the tank body 10 to the top of the tank body 10, and bearings 42 are arranged between the central shaft 41 and the bottom of the tank body 10 and the top of the tank body 10.

[0050] The rotating motor 40 works to rotate the first separation rotating disk 311 and the second separation rotating disk 321. When the first separation rotating disk 311 separates water, the second separation rotating disk 321 idles. When the second separation rotating disk 321 separates organic solution, the first separation rotating disk 311 idles.

[0051] In another preferred embodiment of the utility model, a solid discharge paddle 50 for discharging solids is further provided below the second separation level 32. The solid discharge paddle 50 is located in the isolation ring 15. The solid discharge paddle 50 is connected to a rotary drive mechanism that drives it to rotate so as to scrape the solids at the bottom of the tank body 10 to the solid outlet 14. The solid discharge paddle 50 is a scraping blade that scrapes the solids at the bottom of the tank body 10 to discharge them from the solid outlet 14. Preferably, the solid discharge paddle 50 is also fixed to the central shaft 41 and driven to rotate by the rotary motor 40.

[0052] In another preferred embodiment of the present invention, the pitch angle of the second blade 322 is greater than the pitch angle of the first blade 312, and the pitch angle of the first blade 312 is adjustable to adjust the pitch angle of the first blade 312 according to the water content in the mixture. The higher the water content, the larger the pitch angle of the first blade 312; the pitch angle of the second blade 322 is also adjustable to adjust the pitch angle of the second blade 322 according to the organic solution content in the mixture. The higher the organic solution content, the larger the pitch angle of the second blade 322. Among them, the pitch angles of the first blade 312 and the second blade 322 are both ≤90°, for example, the pitch angle of the first blade 312 is 20° to 80°, which is conducive to the throwing out of water in the mixture, and the pitch angle of the second blade 322 is 81° to 90°, which is conducive to the throwing out of the organic solution in the mixture.

[0053] In another preferred embodiment, when the drainage channel is a plurality of vertically extending slits circumferentially spaced on the blades 302, the pitch angles of all the blades 302 are adjustable, and the pitch angle of the blades 302 when separating the organic solution is greater than the pitch angle of the blades 302 when separating water.

[0054] Specifically, Figure 2 As shown, taking the first paddle 312 as an example, the first paddle 312 includes a plurality of flaps 331 distributed along the outer periphery of the first separation rotating disk 311, and the drainage gap is provided on the flap 331; the lower end of the flap 331 is rotatably connected to the first separation rotating disk 311 through a pin 332, and the two adjacent flaps 331 and the lower end of the flap 331 and the first separation rotating disk 311 are sealed by a membrane cloth 324 (such as a waterproof cloth or a flexible rubber membrane); the upper end of the first separation rotating disk 311 is hinged with a telescopic rod 333, and the telescopic rod 333 is an electric telescopic rod or a pneumatic telescopic rod. The upper end of the telescopic rod 333 is hinged to the inner side of the flap 331, and the pitch angle of the flap 331 can be adjusted by telescopic extension and retraction of the rod 333. The second paddle 322 has the same structure as the first paddle 312, which will not be described in detail.

[0055] It should be noted that when the first separation rotating disk 311 and the second separation rotating disk 321 rotate, the telescopic rod will rotate accordingly. The existing method can be used to solve the problem of cable or air tube winding of the telescopic rod. This is not the innovation of the present invention and will not be described in detail here.

[0056] In the present invention, the separation process of the original three-phase separator of embodiment 1 is as follows:

[0057] S1, detecting the moisture content in the original mixture of water, organic solution and solid, adjusting the rotation speed of the first separation rotating disk 311 of the first separation level 31 and the temperature of the heating unit 20, adjusting the pitch angle of the first blade 312, and when the moisture content is lower than the threshold value, the mixture enters the second separation level 32;

[0058] S2, detect the organic solution content in the mixture of organic solution and solid, adjust the rotation speed of the second separation rotating disk 321 of the second separation level 32 to be equal to or higher than the rotation speed of the first separation rotating disk 311, adjust the temperature of the heating unit 20, adjust the pitch angle of the second paddle 322 to be greater than the pitch angle of the first paddle 312, and when the organic solution content is lower than the threshold value, the remaining solids are discharged from the second separation level 32.

[0059] Specifically, the method for adjusting the pitch angle α of the first blade 312 (ie, the blade separating water) is:

[0060] α=α0+α1η

[0061] Among them, α0 is the initial pitch angle of the first blade 312, for example, α0 is 20°; α1 is the adjustment coefficient of the first blade 312, for example, α1 is 80° / 100%; η is the moisture content in the original mixture of water, organic solution and solid, for example, when the water content is 50%, the value of α1η is 40° and the value of α is 60°.

[0062] Specifically, the method for adjusting the pitch angle β of the second blade 322 (i.e., the blade for separating the organic solution) is:

[0063] β=β0+β1δ

[0064] Among them, β0 is the initial pitch angle of the second blade 322, β0 is greater than α0, for example, β0 is 80 degrees; β1 is the adjustment coefficient of the second blade 322, β1 is less than α1, for example, β1 is 40° / 100%; δ is the content of organic solution in the mixture of organic solution and solid, for example, when the content of organic solution is 10%, the value of α1η is 4°, and the value of β is 83°.

[0065] It should be noted that, when it is a mixture of water, oil and solids, the second separation level 32 is used to separate the oil in the mixture. When the second separation level 32 rotates and separates, the heating unit 20 is also heated and operates in a second temperature state. The second temperature is higher than the first temperature but lower than the boiling point of the oil, thereby ensuring that all the oil is melted into oil and does not vaporize.

[0066] Embodiment 2

[0067] The structure and principle of this embodiment are basically the same as those of the first embodiment, except that the centrifugal separation unit 30 of this embodiment is only provided with one separation level, and in this embodiment, the separation level may be provided with one separation rotating disk 301 or two separation rotating disks 301 .

[0068] like Figure 3 As shown, when a separation rotating disk 301 is set, the original mixture of water, organic solution and solid enters the separation rotating disk 301 of the centrifugal separation unit 30 of the tank body 10 through the feed port 11, the separation rotating disk 301 operates at a first speed, and the heating unit 20 operates at a first temperature state. Under the action of centrifugal force, water in the original mixture is thrown out from the centrifugal separation unit 30 and splashed onto the inner wall of the tank body 10 for separation. The organic solution with a smaller density will not be thrown out due to insufficient centrifugal force. Under the action of the heating unit 20, the water is gasified into water vapor and discharged from the gas outlet 12 to achieve water separation. When there is grease in the mixture, the grease has enough time to melt into oil when separating water. After the water is separated, the separation rotating disk 301 increases the rotation speed to the second rotation speed to provide a greater centrifugal force. Under the action of the centrifugal force, the organic solution (including oil) in the remaining mixture is thrown out and splashed onto the inner wall of the tank body 10 for separation. The organic solution flows down along the inner wall of the tank body 10 to the bottom of the tank body 10 and is discharged from the liquid outlet 13 to achieve the separation of the organic solution; the remaining solid matter is discharged from the solid material outlet 14 to achieve the separation of the solid matter.

[0069] like Figure 4 As shown, when two separation rotating disks 301 are provided, the two separation rotating disks 301 are connected in parallel, the original mixture first enters the upper separation rotating disk 301, and part of the original mixture enters the lower separation rotating disk 301 through the discharge port of the upper separation rotating disk 301, and the two separation rotating disks 301 rotate at the first speed at the same time to separate water. After the water is separated, the speed of the separation rotating disk 301 is increased to the second speed, and the organic solution is separated by a greater centrifugal force to improve efficiency.

[0070] It should be noted that, since the centrifugal separation unit 30 of the second embodiment has only one separation level, the separation process is different from that of the first embodiment. The specific process is as follows:

[0071] S1, detect the moisture content in the original mixture of water, organic solution and solid, adjust the rotation speed of the separation rotating disk 301 of the centrifugal separation unit 30 and the temperature of the heating unit 20, adjust the pitch angle of the blade 302 according to α=α0+α1η to achieve the condition of separating water, and when the moisture content is lower than the threshold, separate the organic solution, and at this time, the angle of the blade 302 needs to be adjusted to;

[0072] S2, detect the organic solution content in the mixture of organic solution and solids, increase the rotation speed of the centrifugal separation unit 30 to provide a greater centrifugal force, adjust the pitch angle of the blade 302 according to β=β0+β1δ, and when the organic solution content is lower than the threshold value, the remaining solids are discharged from the centrifugal separation unit 30.
