DETAILED DESCRIPTION

[0030] To further understand the features, technical means, and specific purposes and functions achieved by the present application, the present application is described in further detail below in conjunction with the drawings and specific embodiments.

[0031] REFERENCE Figures 1-3The application discloses an organic steam condensing system for continuously and on-line separating oil and water, which comprises a heating kettle 1 and a condenser 2, wherein the heating kettle 1 is provided with a transmission pipe 11; the condenser 2 is provided with an air inlet pipe 21 and an air outlet pipe 22, the air inlet pipe 21 and the air outlet pipe 22 are arranged at two ends of the condenser 2 and communicate with the inside of the condenser 2, and the two ends of the transmission pipe 11 communicate with the heating kettle 1 and the air inlet pipe 21 respectively; the inside of the condenser 2 is provided with a condensing assembly 23, a first inner pipe 24 and a second inner pipe 25; the second inner pipe 25 is wrapped in the first inner pipe 24; the second inner pipe 25 is provided with a connecting pipe 251, the two ends of the connecting pipe 251 communicate with the second inner pipe 25 and the air outlet pipe 22 respectively, and a gap for steam passing through is arranged between the second inner pipe 25 and the first inner pipe 24.

[0032] The application realizes the function of prolonging the moving path of steam in the condenser 2 by the heating kettle 1 and the condenser 2 with the first inner pipe 24 and the second inner pipe 25, achieves the effect of prolonging the residence time of steam in the condenser 2, thereby avoiding the situation that steam is discharged from the condenser 2 without being condensed, reducing the processing pressure of subsequent processes, and solving the problem that part of steam cannot be condensed and directly passes through the condenser 2 when the steam flow is large. The transmission pipe 11 and the air inlet pipe 21 are tightly connected through flanges; the mixed solution is heated in the heating kettle 1 to form steam, the steam is transmitted from the transmission pipe 11 into the condenser 2 through the air inlet pipe 21, the high-pressure steam flows between the condenser 2 and the first inner pipe 24, then flows between the first inner pipe 24 and the second inner pipe 25, finally flows from the second inner pipe 25 to the connecting pipe 251, and flows from the connecting pipe 251 to the air outlet pipe 22 for discharge, thereby greatly prolonging the flowing time in the condensing pipe 231, and condensing the steam through the condensing assembly 23 in the process, finally separating the liquefied oil-water mixed solution through an oil-water separator, and the oil-water separator is not shown in the figure.

[0033] Reference Figures 3-5 The condenser 2 is further provided with a communication control device 3, the communication control device 3 comprises first movable vanes 31 and second movable vanes 32; the first movable vanes 31 and the second movable vanes 32 are rotatably installed on the first inner pipe 24 and the second inner pipe 25 respectively.

[0034] The application realizes the function of guiding steam by the first movable vane 31 and the second movable vane 32, and achieves the effect of rotating flow of high-speed flowing steam. The mixed solution is heated to form steam in the heating kettle 1, the steam is transmitted from the air inlet pipe 21 into the condenser 2 through the transmission pipe 11, the high-pressure steam flows from the gap between the condenser 2 and the first inner pipe 24, when the steam passes through the first movable vane 31, the steam is guided by the multiple vanes to advance spirally, and then flows between the first inner pipe 24 and the second inner pipe 25. Similarly, the steam rotates when flowing to the second movable vane 32. When the steam flow is large, the steam will blow the first movable vane 31 and the second movable vane 32, and the first movable vane 31 and the second movable vane 32 rotate. The rotating first movable vane 31 and the second movable vane 32 generate corresponding wind pressure again, avoiding the steam colliding with the inner wall of the condenser 2 when flowing to the end of the first inner pipe 24 away from the air inlet pipe 21, and causing backflow and collision with the entering steam, resulting in the problem of steam disorder. The steam can move stably along the specified path, and finally flows from the second inner pipe 25 to the connecting pipe 251, and from the connecting pipe 251 to the exhaust pipe 22 for discharge, thereby greatly prolonging the flow time in the condensing pipe 231, and condensing the steam by the condensing assembly 23 in the process. Finally, the liquefied oil-water mixed solution is separated by the oil-water separator.

[0035] Referring to Figure 4 , Figure 6 and Figure 7 : The communication control device 3 further comprises a control assembly 33, the control assembly 33 comprising an annular mounting frame 331, a fixed gate 332 and a movable gate 333; the annular mounting frame 331 is sleeved on the first inner pipe 24, and the annular mounting frame 331 is provided with a mounting plate 3311; the fixed gate 332 is installed on the second inner pipe 25, and the fixed gate 332 is located at the end of the second inner pipe 25 close to the exhaust pipe 22; the movable gate 333 is in sliding fit with the inner wall of the first inner pipe 24, and the movable gate 333 is provided with a connecting rod connected with the mounting plate 3311; the movable gate 333 is provided with a matching cylinder 3331, the matching cylinder 3331 is in sliding fit with the connecting pipe 251, and the matching cylinder 3331 and the connecting pipe 251 are both provided with notches; the condenser 2 is further provided with an auxiliary control device 4 for controlling the rotation of the annular mounting frame 331.

[0036] The application realizes the function of controlling the steam communication at the connecting pipe 251 by the ring-shaped mounting frame 331, the fixed shutter 332 and the movable shutter 333, and achieves the effect of controlling the steam flow path. When the steam flow is low, the steam flows directly from the gap of the connecting pipe 251 to the exhaust pipe 22 without passing through the second inner pipe 25, and is discharged from the condenser 2. When the steam is condensed, the steam enters the condenser 2 from the air inlet pipe 21. When the steam flow is low, the steam flows from the space between the inner wall of the condenser 2 and the outer wall of the first inner pipe 24, rotates at the first movable vane 31, and flows spirally. The steam with low flow rate cannot blow the first movable vane 31. At this time, the movable shutter 333 and the fixed shutter 332 are staggered and matched. The gap on the fixed shutter 332 is blocked by the movable shutter 333, and the channel between the first inner pipe 24 and the second inner pipe 25 is blocked. At the same time, the cooperating cylinder 3331 cooperates with the connecting pipe 251, and the gap on the cooperating cylinder 3331 is flush with the gap on the connecting pipe 251. The steam passes through the connecting pipe 251, so that the steam can jump over the second inner pipe 25 and flow out of the condenser 2 directly from the connecting pipe 251. When the steam flow is large, the auxiliary control device 4 controls the rotation of the ring-shaped mounting frame 331. The ring-shaped mounting frame 331 drives the mounting plate 3311 and the movable shutter 333 to rotate, so that the gap of the movable shutter 333 is flush with the gap of the fixed shutter 332. The steam can pass through the movable shutter 333 and the fixed shutter 332, flow between the inner wall of the first inner pipe 24 and the outer wall of the second inner pipe 25, and prolong the flow path of the steam in the condenser 2, thereby improving the condensation effect of the steam.

[0037] With reference to Figure 4 And Figure 7 The auxiliary control device 4 includes a first transmission assembly 41, a first bevel gear ring 42 and a spring 43. The two ends of the first transmission assembly 41 are respectively in transmission connection with the first bevel gear ring 42 and the first movable vane 31. The first bevel gear ring 42 is fixedly sleeved on the ring-shaped mounting frame 331. The movable shutter 333 is provided with a second connecting rod 3333. The spring 43 is wound on the second inner pipe 25, and the two ends of the spring 43 are respectively connected with the second inner pipe 25 and the second connecting rod 3333.

[0038] The application realizes the function of controlling the rotation of the annular mounting frame 331 through the first transmission assembly 41, the first bevel gear ring 42 and the second connecting rod 333, and achieves the effect of automatically closing the passage at the gap of the connecting pipe 251 and opening the passage at the movable gate 333 when the steam flow is large. When the steam flow is small, the first movable vane 31 does not rotate, the annular mounting frame 331 and the movable gate 333 are in the reset state under the elastic force of the spring 43, the passage at the gap of the connecting pipe 251 is opened, the passage at the movable gate 333 is closed, and the steam directly flows into the exhaust pipe 22 from the gap of the connecting pipe 251; when the steam flow is large, under the blowing action of the steam, the first movable vane 31 rotates and drives the first bevel gear ring 42 to rotate through the transmission of the first transmission assembly 41 against the elastic force of the spring 43, the first bevel gear ring 42 drives the annular mounting frame 331 to rotate, the annular mounting frame 331 drives the mounting plate 3311 and the movable gate 333 to rotate, the gap of the movable gate 333 is flush with the gap of the fixed gate 332, the steam can pass through the movable gate 333 and the fixed gate 332, flow between the inner wall of the first inner pipe 24 and the outer wall of the second inner pipe 25, the flow path of the steam in the condenser 2 is lengthened, and the condensation effect of the steam is improved.

[0039] With reference to Figure 4 And Figure 8 The first transmission assembly 41 comprises a spur gear ring 411, a first rotating shaft 412, a rotating gear 413 and a first bevel gear 414; the spur gear ring 411 is rotatably installed on the first inner pipe 24 and connected with the first movable vane 31; the first rotating shaft 412 is rotatably installed on the outer wall of the first inner pipe 24; the rotating gear 413 is sleeved on the first rotating shaft 412 and in meshing transmission connection with the spur gear ring 411; and the first bevel gear 414 is sleeved on the first rotating shaft 412 and in transmission connection with the first bevel gear ring 42.

[0040] The application realizes the effect of transmission connection between the first movable vane 31 and the annular mounting frame 331 through the spur gear ring 411, the first rotating shaft 412, the rotating gear 413 and the first bevel gear 414, and achieves the effect of controlling the rotation of the annular mounting frame 331 through the first movable vane 31. When the steam flow is large, under the blowing action of the steam, the first movable vane 31 rotates and drives the spur gear ring 411 to rotate, the spur gear ring 411 drives the rotating gear 413 in transmission connection therewith to rotate, the rotating gear 413 drives the first rotating shaft 412 and the first bevel gear 414 to rotate, the first bevel gear 414 drives the first bevel gear ring 42 to rotate, the first bevel gear ring 42 drives the annular mounting frame 331 to rotate, the annular mounting frame 331 drives the mounting plate 3311 and the movable gate 333 to rotate, the gap of the movable gate 333 is flush with the gap of the fixed gate 332, the passage at the movable gate 333 is opened, and the steam can pass through the movable gate 333 and the fixed gate 332.

[0041] With reference to Figure 8 And Figure 9 The auxiliary control device 4 further comprises a second transmission assembly 44, the second transmission assembly 44 comprising a second rotating shaft 441, a mounting ring 442, a second bevel gear ring 443 and a third bevel gear ring 444; the second rotating shaft 441 is provided with at least three and is rotatably mounted on the mounting plate 3311, and a damping wheel 4411 is sleeved on the second rotating shaft 441 and is in interference fit with the second rotating shaft 441; the mounting ring 442 is in rolling connection with a plurality of damping wheels 4411, and the second bevel gear 4421 is rotatably mounted on the mounting ring 442; the second bevel gear ring 443 and the third bevel gear ring 444 are rotatably sleeved on the annular mounting frame 331, are coaxially fixedly connected, are in meshing transmission connection with the second bevel gear 4421, and are in meshing transmission connection with the first bevel gear 414.

[0042] The second rotating shaft 441, the mounting ring 442, the second bevel gear ring 443 and the third bevel gear ring 444 realize the function of setting damping, so that when the steam flow is large, the first movable vane 31 can not hinder the rotation of the movable gate 333 after the movable gate 333 is opened. When the steam flow is large, the first movable vane 31 rotates under the action of steam blowing, drives the spur gear ring 411 to rotate, drives the rotating gear 413 in transmission connection with the spur gear ring 411 to rotate, drives the first rotating shaft 412 and the first bevel gear 414 to rotate, drives the first bevel gear ring 42 to rotate, drives the annular mounting frame 331 to rotate, drives the mounting plate 3311 and the movable gate 333 to rotate, so that the gap of the movable gate 333 is flush with the gap of the fixed gate 332, the channel at the movable gate 333 is opened, and steam can pass through the movable gate 333 and the fixed gate 332; after the movable gate 333 is completely opened, the movable gate 333 stops rotating, and the first bevel gear ring 42 stops rotating; at this time, if the steam flow rate is still high, the first movable vane 31 still rotates and drives the third bevel gear ring 444 to rotate through the first transmission assembly 41, and the first bevel gear ring 42 cannot continue to rotate at this time, so that the rotation of the third bevel gear ring 444 drives the second bevel gear 4421 to rotate, and the rotation of the second bevel gear 4421 drives the mounting ring 442 to rotate, and the mounting ring 442 drives the damping wheel 4411 to rotate. The damping provided by the damping wheel 4411 makes the mounting ring 442 not rotate when the movable gate 333 is not opened, so that the rotation of the first bevel gear 414 can stably drive the movable gate 333 to rotate and open the channel.

[0043] With reference to Figures 2-4 And Figure 7The condensing assembly 23 comprises a condensing pipe 231, a liquid inlet pipe 232 and a liquid outlet pipe 233; the condensing pipe 231 is provided with four sections, and a plurality of condensing pipes 231 are spirally wound on the first inner pipe 24 and the second inner pipe 25 respectively; the condensing pipe 231 is provided with a through hole 2311 for steam to pass through; the liquid inlet pipe 232 and the liquid outlet pipe 233 are arranged on the condenser 2, and the two ends of the condensing pipe 231 are communicated with the liquid inlet pipe 232 and the liquid outlet pipe 233 respectively.

[0044] The condensing pipe 231, the liquid inlet pipe 232 and the liquid outlet pipe 233 realize the function of condensing steam. When the steam passes through the through hole 2311, the steam is in contact with the outer wall of the condensing pipe 231, so that the steam is liquefied by cooling, and the spiral condensing pipe 231 greatly increases the contact area between the steam and the condensing pipe 231, thereby improving the condensing effect.

[0045] With reference to Figure 3 and Figure 4 The first inner pipe 24 is provided with an arc-shaped guide shell 26 at one end close to the air inlet pipe 21.

[0046] The arc-shaped guide shell 26 realizes the function of guiding the flow direction of the steam. After the steam enters the condenser 2 through the air inlet pipe 21, the steam is in contact with the convex surface of the guide shell 26, and under the guidance of the arc-shaped convex surface, the steam flows between the inner wall of the condenser 2 and the outer wall of the first inner pipe 24, and after entering the inside of the first inner pipe 24, the steam flows into the second inner pipe 25 again under the guidance of the arc-shaped concave surface of the guide shell 26, thereby stably guiding the flow direction of the steam and reducing the turbulence of the steam as much as possible.

[0047] With reference to Figure 1 The transmission pipe 11 is provided with an electromagnetic valve 111.

[0048] The electromagnetic valve 111 realizes the function of controlling the flow of the transmission pipe 11. The electromagnetic valve 111 is electrically connected with the controller; when the operator heats the mixed solution through the heating kettle 1 to generate steam, the opening and closing of the electromagnetic valve 111 is flexibly adjusted by the air pressure in the heating kettle 1 to adjust the flow of the transmission pipe 11, thereby being capable of controlling the flow of the steam in the condenser 2 and greatly improving the control flexibility of the steam condensing system.

[0049] With reference to Figure 1 The first inner pipe 24 is provided with an arc-shaped sliding groove 241 at the end close to the air outlet pipe 22, and the first connecting rod 3332 is in sliding cooperation with the arc-shaped sliding groove 241.

[0050] The present application realizes the function of limiting the rotation range of the first connecting rod 3332 through the arc-shaped sliding groove 241. The rotation of the movable damper 333 is driven by the rotation of the first movable vane 31, and the rotation of the first movable vane 31 is only related to the flow of steam. Therefore, the arc-shaped sliding groove 241 is arranged to limit the rotation range of the first connecting rod 3332, and to prevent the movable damper 333 from being excessively opened and closed in the fully opened and fully closed conditions, thereby improving the working stability of the control assembly 33.

[0051] The above embodiments only express one or several embodiments of the present application, and the description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the present application. It should be noted that for those skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
