[0031] In the related art, the methanol separator may appear waxing phenomenon in the process of separating methanol, thereby affecting the separation efficiency of methanol.
[0032] Therefore, the inventor proposes a wax removal device 10, which comprises a gas feeding pipeline 11 and a heat dissipation rod 12. The gas feeding pipeline 11 can transport steam into the hollow of the heat dissipation rod 12, and then the steam is transported into the desalted water in the methanol separator 21 through a plurality of second outlets 122 on the circumferential surface of the heat dissipation rod 12, so as to heat the desalted water, and then the wax on the inner wall of the methanol separator 21 melts into the desalted water when the temperature of the methanol separator 21 rises to the melting point. Finally, the opening on the methanol separator 21 (such as the opening through which the separated methanol flows out of the methanol separator 21) can be opened, so that the desalted water mixed with the wax liquid can flow out, thereby achieving the removal of the waxing in the methanol separator 21.
[0033] First aspect
[0034] The present disclosure provides a wax removal device 10, as shown in Figures 1 to 3 The wax removal device 10 can comprise a gas feeding pipeline 11 and a heat dissipation rod 12. The gas feeding pipeline 11 has a first inlet 111 and a first outlet 112, and the gas feeding pipeline 11 is provided with a valve 113. The heat dissipation rod 12 has a second inlet 121 and a plurality of second outlets 122. The second inlet 121 is located at one end of the length direction of the heat dissipation rod 12 and is in communication with the first outlet 112. The plurality of second outlets 122 are arranged on the circumferential surface of the heat dissipation rod 12. The heat dissipation rod 12 is hollow so that the second inlet 121 is in communication with the plurality of second outlets 122 respectively. Among the plurality of second outlets 122, the distance between at least two second outlets 122 and the second inlet 121 is different.
[0035] The air supply line 11 is at least used to transport steam. The air supply line 11 has a first inlet 111 and a first outlet 112. Steam can enter from the first inlet 111 and be sent to a designated location from the first outlet 112. For example, since the first outlet 112 is connected to the second inlet 121 of the heat sink 12, the air supply line 11 can transport steam to the second inlet 121 of the heat sink 12. The first inlet 111 can correspond to one end of the air supply line 11, or to the side surface of the air supply line 11 in the direction in which it extends; the first outlet 112 can correspond to the other end of the air supply line 11, or to the side surface of the air supply line 11 in the direction in which it extends; for example, the openings at both ends of the air supply line 11 are the first inlet 111 and the first outlet 112, respectively. The valve 113 can be set at the first inlet 111, or at the first outlet 112, or on the air supply line 11 between the first inlet 111 and the first outlet 112; the valve 113 can control the steam delivery state at its location, and the delivery state includes: delivering steam, not delivering steam, increasing the unit steam delivery volume, decreasing the unit steam delivery volume, etc.; the valve 113 can be a stop valve or other settings.
[0036] The heat sink 12 is at least used to disperse the steam delivered by the air supply line 11 into the desalted water in the methanol separator 21, so that the temperature of the desalted water at different locations can be increased synchronously, and after the temperature is increased to the melting point of the wax, the wax on the inner wall of the methanol separator 21 is melted in the desalted water. The connection between the heat sink 12 and the air supply line 11 can be as follows Figure 3 The connection shown in the figure is through a thread 123, and it can also be connected by a cable tie, or it can be connected by other structural parts. The heat sink 12 can be straight, wavy, broken line, or other shapes along its length. The heat sink 12 is hollow, and the second inlet 121 at one end of the heat sink 12 is connected to the multiple second outlets 122 on the side surface of the heat sink 12 through the hollow. In this way, after the steam from the first outlet 112 is transported to the second inlet 121, it can be transported to the multiple second outlets 122 through the hollow, and then flow to different positions in the desalted water in the methanol separator 21 respectively, so as to heat different positions of the desalted water at the same time, thereby improving the heating efficiency and thus improving the dewaxing efficiency. Among the multiple second outlets 122, the distance between at least two second outlets 122 and the second inlet 121 is different. In this way, when the multiple second outlets 122 are located in the desalted water, the multiple second outlets 122 correspond to different depth positions in the desalted water, so that the desalted water at different depths can be heated. The plurality of second outlets 122 may be evenly distributed or unevenly distributed; the second outlets 122 may be in a circular, rectangular, pentagonal, or other shape, and the shapes of different second outlets 122 may be the same or different.
[0037] In one example, seeFigure 1 As shown, the wax removal device 10 can include: a gas feeding line 11, the gas feeding line 11 having a first inlet 111 and a first outlet 112 at two ends thereof, and a valve 113 arranged at a position of the gas feeding line 11 corresponding to the first inlet 111 and the first outlet 112; and a heat dissipation rod 12, the heat dissipation rod 12 having a second inlet 121 and a plurality of second outlets 122, the second inlet 121 being arranged at one end of the heat dissipation rod 12 in a length direction thereof and being in communication with the first outlet 112, the plurality of second outlets 122 being arranged on a circumferential surface of the heat dissipation rod 12, the heat dissipation rod 12 being hollow so that the second inlet 121 is in communication with the plurality of second outlets 122 respectively, and among the plurality of second outlets 122, distances between at least two second outlets 122 and the second inlet 121 are different. An operation method of the wax removal device 10 includes:
[0038] S101: injecting desalted water into the methanol separator 21;
[0039] S102: inserting the heat dissipation rod 12 into the methanol separator 21, and at least partially immersing the heat dissipation rod 12 in the desalted water;
[0040] S103: feeding steam into the first inlet 111 of the gas feeding line 11, the fed steam being transported to the plurality of second outlets 122 of the heat dissipation rod 12 via the first inlet 111 of the gas feeding line 11, the gas feeding line 11, the first outlet 112 of the gas feeding line 11, the second inlet 121 of the heat dissipation rod 12 and the hollow of the heat dissipation rod 12, and then being fed into different positions of the desalted water respectively, so as to increase the temperature of the desalted water.
[0041] S104: after a target time, opening an opening of the methanol separator 21 for separating methanol, so that the desalted water mixed with wax liquid is discharged via the opening, thereby realizing the wax removal operation of the methanol separator 21.
[0042] S105: closing the opening in S104, so as to prepare for the separation of methanol.
[0043] Here, the target time can be obtained through multiple experiments, or can be obtained by experience of the staff, etc.
[0044] In this embodiment, the gas feeding pipeline 11 of the wax removing device 10 is used to transport steam to the second inlet 121 of the heat dissipation rod 12, and then the steam is transported to the multiple second outlets 122 through the hollow of the heat dissipation rod 12, respectively. The multiple second outlets 122 correspond to different positions in the desalted water in the methanol separator 21, so that the desalted water can be heated, and then the wax on the inner wall of the methanol separator 21 is melted into the desalted water when the temperature rises to the melting point. Finally, the outlet of the methanol separator 21 (for example, the opening through which the separated methanol flows out of the methanol separator 21) can be opened, so that the desalted water mixed with the wax liquid can flow out, thereby achieving the removal of the wax in the methanol separator 21. In addition, since the multiple second outlets 122 can disperse a large amount of steam into the desalted water, the phenomenon of water hammer caused by the concentration of a large amount of steam in the same position in the methanol separator 21 can be reduced, thereby reducing the probability of damage to the inside of the methanol separator 21.
[0045] In some embodiments, the other end of the heat dissipation rod 12 in the length direction is also provided with multiple second outlets 122, which are respectively communicated with the second inlet 121 through the hollow of the heat dissipation rod 12. That is, the heat dissipation rod 12 is not only provided with multiple second outlets 122 on the circumferential surface and communicated with the second inlet 121, but also provided with multiple second outlets 122 at the position opposite to the second inlet 121, so that the steam of the second inlet 121 can be transported into the desalted water through the multiple second outlets 122 on the circumferential surface of the heat dissipation rod 12 and the multiple second outlets 122 at the other end of the heat dissipation rod 12, respectively, so as to accelerate the temperature rising rate of the desalted water, and then accelerate the melting speed of the wax on the inner wall of the methanol separator 21 to improve the wax removal efficiency.
[0046] In some embodiments, the multiple second outlets 122 at the other end of the heat dissipation rod 12 in the length direction can have the same shape / size, or different shapes / sizes; the multiple second outlets 122 at the other end of the heat dissipation rod 12 in the length direction can be uniformly distributed, or not uniformly distributed. The shape of the multiple second outlets 122 at the other end of the heat dissipation rod 12 in the length direction can be the same as or different from the shape / size of the multiple second outlets 122 on the circumferential surface of the heat dissipation rod 12.
[0047] In some embodiments, referring to Figure 3As shown, the heat dissipation rod 12 is linear along its length direction, and the plurality of second outlets 122 are arranged in multiple rows and columns, and the multiple columns of second outlets 122 respectively extend along the length direction of the heat dissipation rod 12 and are parallel to each other. That is, on the circumferential surface of the heat dissipation rod 12, multiple columns of second outlets 122 are arranged along the length direction of the heat dissipation rod 12, so that the desalted water at different positions around the heat dissipation rod 12 can be heated simultaneously, thereby accelerating the temperature rise of the desalted water; the multiple columns of second outlets 122 are parallel to each other, so that the desalted water at different positions around the heat dissipation rod 12 can be uniformly heated, and the parallel arrangement can improve the visual effect of the heat dissipation rod 12.
[0048] Among them, the multiple second outlets 122 in one column can be one-to-one opposite to the multiple second outlets 122 in another column, or can be staggered with each other. In one column, the distance between the adjacent two second outlets 122 can be a fixed constant.
[0049] In some embodiments, referring to Figure 2 As shown, the gas supply pipeline 11 includes: a first pipeline 114 and a second pipeline 115; the first pipeline 114 has a third inlet 1141 and a third outlet 1142; the second pipeline 115 has a fourth inlet 1151 and a fourth outlet 1152, the fourth inlet 1151 communicates with the third outlet 1142, and the second pipeline 115 can be bent so that the fourth outlet 1152 can change its position relative to the fourth inlet 1151; wherein the third inlet 1141 is the first inlet 111, and the fourth outlet 1152 is the first outlet 112. In other words, the first pipeline 114, the second pipeline 115 and the heat dissipation rod 12 are connected in sequence, so that the steam is transported to the heat dissipation rod 12 through the first pipeline 114 and the second pipeline 115; and since the second pipeline 115 can be bent, the position of the fourth outlet 1152 relative to the fourth inlet 1151 can be adjusted, and thus the position of the heat dissipation rod 12 relative to the first pipeline 114 can be adjusted, so that different installation spaces can be adapted (for example, the second pipeline 115 is bent according to the curved installation space, so that the wax removal device 10 can be installed in the curved installation space to complete the wax removal work).
[0050] Among them, the first pipeline 114 can be a non-bendable pipe or a bendable pipe; in the case that the first pipeline 114 is a bendable pipe, the first pipeline 114 and the second pipeline 115 can be integrally made of the same specification pipe material. The second pipeline 115 can be a hose (such as a plastic pipe, a rubber pipe, etc.), a corrugated pipe, etc., so as to have bending performance; in the case that the second pipeline 115 is a hose, the steam pressure in the gas supply pipeline 11 can be not greater than 1 MPa, so as to prevent the second pipeline 115 from being cracked.
[0051] In some embodiments, referring to Figure 2As shown, the first pipeline 114 includes a main pipeline 1143 and a plurality of branch pipelines 1144; the main pipeline 1143 has a third inlet 1141; the plurality of branch pipelines 1144 are respectively in communication with the main pipeline 1143, and the plurality of branch pipelines 1144 respectively have a third outlet 1142; wherein the number of the second pipelines 115 and the number of the heat dissipation rods 12 are both plural, the fourth inlets 1151 of the plurality of second pipelines 115 are respectively in communication with the third outlets 1142 of the plurality of branch pipelines 1144, and the plurality of fourth outlets 1152 of the plurality of second pipelines 115 are respectively connected with the plurality of heat dissipation rods 12.
[0052] Here, the main pipeline 1143 and the plurality of branch pipelines 1144 can be connected through connecting pipes, for example, the number of the branch pipelines 1144 is two, and the main pipeline 1143 is respectively connected with the two branch pipelines 1144 through a tee joint. In the case where the first pipeline 114 includes the main pipeline 1143 and the plurality of branch pipelines 1144, the steam can be delivered to the second pipelines 115 and the heat dissipation rods 12 connected with the plurality of branch pipelines 1144 through the first pipeline 114, so that the wax precipitation in the plurality of different methanol separators 21 can be removed, thereby reducing the wax removal cost; for example, see Figure 2 As shown, the number of the branch pipelines 1144 is two, and the main pipeline 1143 is respectively connected with the two branch pipelines 1144 through a tee joint, so that the steam can be delivered to the two second pipelines 115 and the two heat dissipation rods 12 connected with the two branch pipelines 1144 through the first pipeline 114, thereby the wax precipitation in the two methanol separators 21 can be removed, thereby reducing the wax removal cost.
[0053] In some embodiments, the valve 113 can include a first valve and / or a second valve; the first valve is arranged in the main pipeline 1143; and the second valve is arranged in the branch pipeline 1144.
[0054] In the case where the main pipeline 1143 is provided with the first valve, the steam delivery state of the main pipeline 1143 can be controlled through the first valve, and the delivery state includes delivering steam, not delivering steam, increasing the unit steam delivery amount, reducing the unit steam delivery amount, etc.
[0055] In the case where the branch pipeline 1144 is provided with the second valve, the steam delivery state of the branch pipeline 1144 can be controlled through the second valve, and the delivery state includes delivering steam, not delivering steam, increasing the unit steam delivery amount, reducing the unit steam delivery amount, etc.
[0056] The second aspect
[0057] The present disclosure also provides a methanol separation system 20, see Figure 1 and Figure 2As shown, the methanol separation system 20 can comprise a methanol separator 21 and the wax removal device 10 of any one of the first aspect, the heat sink rod 12 of the wax removal device 10 being detachably inserted into the methanol separator 21 and immersed in the desalted water in the methanol separator 21.
[0058] The upper end of the methanol separator 21 can be provided with a wax removal inlet and outlet, so that the heat sink rod 12 can enter the methanol separator 21 through the wax removal inlet and outlet and be immersed in the desalted water in the methanol separator 21, and can be removed from the wax removal inlet and outlet to be separated from the methanol separator 21. The lower end of the methanol separator 21 has an opening for discharging separated methanol, which can also be used to discharge desalted water mixed with wax liquid to reuse the opening of the methanol separator 21 for discharging separated methanol.
[0059] In some embodiments, referring to Figure 1 and Figure 2 As shown, the methanol separator 21 has a first opening 211 and a second opening 212 communicating the internal space of the methanol separator 21, the first opening 211 is located higher than the second opening 212, and the first opening 211 is provided with a first closure 213 capable of closing the first opening 211, and the second opening 212 is provided with a second closure capable of closing the second opening 212.
[0060] After the wax in the inner wall of the methanol separator 21 melts into the desalted water, the first opening 211 and the second opening 212 can be opened, so that the desalted water mixed with wax liquid can be sent out through the first opening 211 and the second opening 212 respectively; and because the first opening 211 is located higher than the second opening 212, the desalted water mixed with wax liquid located above the first opening 211 can be sent out through the first opening 211 and the second opening 212, and the desalted water mixed with wax liquid located below the first opening 211 can be sent out through the second opening 212. The first opening 211 and the second opening 212 simultaneously send out the desalted water mixed with wax liquid, so as to improve the discharge rate and thus improve the wax removal efficiency.
[0061] The first closure 213 can be rotatably connected to the first opening 211, for example: one end of the first closure 213 is connected to the first opening 211 through a hinge, and in the case that the first closure 213 closes the first opening 211, the other end of the first closure 213 is adsorbed to the methanol separator 21 at the first opening 211 to be fixedly connected; the first closure 213 can also be detachably connected to the first opening 211 by screws or other fasteners.
[0062] The second closure can refer to the arrangement of the first closure 213, or can be as Figure 1 and Figure 2The discharge pipeline and the control valve 214 (such as a stop valve, etc.) arranged on the discharge pipeline are shown in the figure. The control valve 214 can control the opening or closing of the second opening 212.
[0063] The first opening 211 has a large caliber so that the staff can enter or exit the methanol separator 21, thereby allowing the staff to enter the methanol separator 21 to further clean the interior of the methanol separator 21 after the wax removal operation of the methanol separator 21 by the wax removal device 10.
[0064] In some embodiments, as shown in Figure 1 and Figure 2 The temperature detector 215 can be a thermocouple thermometer, an infrared thermometer, or other temperature detectors suitable for high-temperature measurement.
[0065] The temperature detector 215 can be a thermocouple thermometer, an infrared thermometer, or other temperature detectors suitable for high-temperature measurement.
[0066] In some embodiments, as shown in Figure 1 and Figure 2 The temperature detector 215 can be a thermocouple thermometer, an infrared thermometer, or other temperature detectors suitable for high-temperature measurement.
[0067] In the case where the temperature detector 215 is immersed in the desalted water in the methanol separator 21, when the temperature value detected by the temperature detector 215 is equal to the melting point of the wax, it can be basically confirmed that the wax has melted in the desalted water. In the case where the temperature detector 215 is located above the desalted water in the methanol separator 21, when the temperature value detected by the temperature detector 215 is greater than the melting point of the wax, it can be basically confirmed that the wax has melted in the desalted water. Here, due to the influence of the temperature of the environment where the methanol separator 21 is located and the amount of wax inside, etc., the word basically is used in the above description; the specific melting temperature can be averaged after multiple wax removal operations or obtained by other means, and then whether the wax has melted in the desalted water can be confirmed by whether the temperature value detected by the temperature detector 215 is equal to the melting temperature.
