Description

Technical Field

[0001] The present invention relates to the technical field of chemical equipment, and particularly to a dewaxing device. Background Art

[0002] In the purification process of petroleum and natural gas, ethylene glycol is often added as a solvent. Since the price of ethylene glycol is relatively high, generally, after the purification is completed, the ethylene glycol in the solution is recovered. The solution contains a large amount of impurities, such as a large amount of wax separated from petroleum and natural gas, as well as sediment such as silt and rust. Therefore, a dewaxing device is needed to remove the impurities in the solution.

[0003] In the prior art, the dewaxing device mainly consists of a chamber for containing liquid. When the solution enters the dewaxing device, it will be left standing in the chamber for a period of time to wait for the solution to stratify. The impurities in the solution will automatically stratify. Among them, the wax will float on the upper part of the solution, and sediment such as rust and silt will settle to the bottom of the solution. The solution is in the middle position. At this time, the middle part of this solution is discharged through the discharge pipe, and the impurities are left in the dewaxing device.

Figure 9 It is a schematic structural diagram of the wax collection tank of the wax removal device provided by an embodiment of the present invention. Figure 10 It is a schematic structural diagram of the opening of the first partition plate of the wax removal device provided by an embodiment of the present invention.

[0080] As Figure 1 and Figure 2 shown, the wax removal device provided by an embodiment of the present invention includes a wax removal tank body 100. There is a cavity inside the wax removal tank body 100. Inside the cavity, there are a first partition plate 101, a second partition plate 201, a first wax collection tank 2, and a first communication pipe 302. The first partition plate 101 and the second partition plate 201 are vertically arranged in the cavity, jointly dividing the cavity into a first chamber 10, a second chamber 20, and a third chamber 30. There is a gap between the upper end of the first partition plate 101 and the inner wall of the cavity, and there is a gap between the upper end of the second partition plate 201 and the inner wall of the cavity. A liquid inlet is provided on the first chamber 10, and a liquid outlet is provided on the third chamber 30.

[0081] The first wax collection tank 2 is arranged in the second chamber 20. There is a first wax collection port 21 on the first wax collection tank 2. The first wax collection port 21 is located in the upper part of the cavity. The first wax collection port 21 is communicated with a first wax collection pipe 212. The first wax collection pipe 212 passes through the cavity and is connected to an external wax collection device.

[0082] As an optional implementation manner, a first through hole is provided on the second partition plate 201. The first through hole is used for passing through the first communication pipe 302. The first communication pipe 302 connects the second chamber 20 and the third chamber 30. Among them, the outlet position of the first communication pipe 302 is higher than its inlet position.

[0083] Furthermore, the wax removing device further includes: a third partition 301, a second wax collecting tank 3, and a second communication pipe 401; a first partition 101, a third partition 301, and a second partition 201 are vertically arranged in the cavity, and together divide the cavity into a first chamber 10, a second chamber 20, a fourth chamber 40, and a third chamber 30.

[0084] As a preferred embodiment, the heights of the first partition 101, the third partition 301, and the second partition 201 do not exceed four-fifths of the height of the wax removing tank body 100.

[0085] Among them, there are the following two possible implementation manners for the setting of the second wax collecting tank 3:

[0086] One possible implementation manner is: as Figure 3 and Figure 4 shown, the second wax collecting tank 2 is arranged in the fourth chamber 40, and a second wax collecting port 31 is arranged on the second wax collecting tank 3; a second through hole is arranged on the third partition 301, and the second through hole is used for passing through a converging pipe 211, and the converging pipe 211 connects the second wax collecting port 31 and the first wax collecting pipe 212.

[0087] Specifically, as Figure 7 shown, the first wax collecting port 21 of the first wax collecting tank 2 is connected to the second wax collecting port 31 of the second wax collecting tank 3 through the converging pipe 211 and is connected to the first wax collecting pipe 212.

[0088] Another possible implementation manner is: the second wax collecting tank 2 is arranged in the fourth chamber 40, and a second wax collecting port 31 is arranged on the second wax collecting tank 3; the second wax collecting port 31 is located in the upper part of the cavity, and the connection mode of the second wax collecting port 31 with the external wax collecting device is the same as the connection mode of the first wax collecting port 21 with the external wax collecting device (not shown in the figure).

[0089] As an alternative embodiment, a third through hole is further arranged on the third partition 301, and the third through hole is used for passing through the second communication pipe 401. The second communication pipe 401 connects the second chamber 20 and the fourth chamber 40; the outlet position of the second communication pipe 401 is higher than its inlet position.

[0090] It should be noted that the outlet positions of the first connecting pipe 302 and the second connecting pipe 401 are higher than their inlet positions to increase the static layering effect of the solution in the fourth chamber 40 and the second chamber 20 connected to the inlets of the first connecting pipe 302 and the second connecting pipe 401. Taking the second connecting pipe 401 as an example, the inlet of the second connecting pipe 401 is connected to the second chamber 20, and the outlet is connected to the fourth chamber 40. Therefore, the solution needs to enter from the lower inlet of the second connecting pipe 401 and be discharged from the higher outlet when moving from the second chamber 20 to the fourth chamber 40. During the whole process, the solution moves upward in the second connecting pipe 401. That is to say, when the liquid level height of the solution in the second chamber 20 is higher than the outlet height of the second connecting pipe 401, the solution can be discharged from the outlet of the second connecting pipe 401. Before the liquid level height of the solution in the second chamber 20 reaches the outlet height of the second connecting pipe 401, the solution always stays in the second chamber 20 and cannot enter the fourth chamber 40. This increases the residence time of the solution in the second chamber 20, so that the wax and precipitate impurities in the solution can be fully layered, which is beneficial for the solution with the least impurities in the middle to enter the fourth chamber 40 from the second connecting pipe 401.

[0091] It should be noted that, as Figure 4 shown, the first connecting pipe 302 and the second connecting pipe 401 can be relatively arranged at the diagonal positions, so as to increase the flow path of the solution, extend the sedimentation separation time, and further promote the layering effect of the solution. For example, when the first connecting pipe 302 is arranged on one side close to the wax collection pipe 100, the second connecting pipe 401 is arranged on the other side close to the wax collection pipe 100.

[0092] In addition, in order to detect the temperature and liquid level in the wax removal tank body 100, a plurality of temperature monitoring devices such as thermometers and liquid level monitoring devices such as liquid level gauges (not shown in the figure) can be provided. The number and specific types of the temperature monitoring devices and the liquid level monitoring devices are not limited in this embodiment.

[0093] As an optional implementation manner, a limiting mechanism 6 can be respectively arranged at the outlet positions of the first connecting pipe 302 or / and the second connecting pipe 401; the limiting mechanism 6 includes a driving member 601 and a baffle 602. The baffle 602 is arranged inside the first connecting pipe 302 or / and the second connecting pipe 401, and the driving member 601 is connected to the baffle 602 and drives the baffle 602 to rotate horizontally with the driving member 601 as the rotation axis.

[0094] Specifically, taking the connection between the first connecting pipe 302 and the limiting mechanism 6 as an example, as Figure 5 and Figure 6As shown, the limiting mechanism 6 is detachably connected to the inside of the outlet position of the first communication pipeline 302. For example, it can be connected by hinging, threaded connection, pin connection or snap connection. In this embodiment, the specific structure of the detachable connection is not limited.

[0095] It should be noted that the baffle 602 can be a semi-circular thin sheet structure, and the diameter of the baffle 602 is slightly smaller than the diameter of the first communication pipeline 302, so as to maximize the regulation of the liquid flow rate in the first communication pipeline 302. However, the specific shape and size of the baffle 602 in the present invention are not limited, nor are they limited to the above examples.

[0096] Since the positions of the first wax collecting tank 2 and the second wax collecting tank 3 are fixed, when the wax content in the dewaxing tank body 100 is relatively high, in order to prevent some wax from not overflowing into the first wax collecting tank 2 or / and the second wax collecting tank 3, the driving member 601 drives the baffle 602 to rotate horizontally with the driving member 601 as the rotation axis. When the positional relationship between the baffle 602 and the first communication pipeline 302 is as Figure 6 shown, the baffle 602 blocks part of the liquid flow rate at the outlet of the first communication pipeline 302, so that the liquid levels in the second chamber 20 and the fourth chamber 40 rise, causing the wax to overflow into the first wax collecting tank 2 or / and the second wax collecting tank 3, improving the wax collecting effect.

[0097] The working principle when the second communication pipeline 401 is connected to the limiting mechanism 6 is the same as that of the first communication pipeline 302, and the same technical effect can be achieved, so it will not be elaborated here.

[0098] It should be noted that according to the requirements of the actual application scenario, the limiting mechanism 6 can be only arranged on the first communication pipeline 302, can be only arranged on the second communication pipeline 401, or can be arranged on both the first communication pipeline 302 and the second communication pipeline 401 at the same time, as long as it can achieve the effect of raising the liquid level. The present invention is not limited thereto.

[0099] In addition, a limiting part (not shown in the figure) can be arranged in the limiting mechanism 6. The limiting part can be a positioning pin or a blocking protrusion arranged on the inner wall of the first communication pipeline 302 close to the baffle 602, as long as it can play the role of limiting the rotation angle of the baffle 602. The present invention is not limited thereto, nor is it limited to the above examples.

[0100] As an optional implementation manner, the dewaxing device further includes: a liquid inlet pipeline 1; the liquid inlet pipeline 1 is communicated with the liquid inlet of the first chamber 10. The first end of the liquid inlet pipeline 1 is located outside the dewaxing tank body 100, the second end of the liquid inlet pipeline 1 is located in the first chamber 10 of the dewaxing tank body 100, and the second end of the liquid inlet pipeline 1 is bent upward.

[0101] It should be noted that the second end of the liquid inlet pipe 1 is bent upward, which can make the solution not flow straight into the first chamber when passing through the liquid inlet pipe 1. By setting the upward bend, the flow rate of the solution when entering the first chamber can be slowed down, avoiding large disturbances to the solution in the first chamber and reducing the impact on the inner wall of the dewaxing tank 1, thereby preventing corrosion.

[0102] In addition, the dewaxing device further includes: a liquid outlet pipe 5; the liquid outlet pipe 5 is communicated with the liquid outlet of the third chamber 30. The first end of the liquid outlet pipe 5 is located in the third chamber 30 of the dewaxing tank 100, and the second end of the liquid outlet pipe 5 is located outside the dewaxing tank 100.

[0103] As Figure 8 shown, the liquid outlet pipe 5 includes a first liquid outlet pipe 501 and a second liquid outlet pipe 502. The first liquid outlet pipe 501 is higher than the second liquid outlet pipe 502. The first end of the first liquid outlet pipe 501 is communicated with the first end of the second liquid outlet pipe 502 through a first liquid outlet connecting pipe 503, and the second end of the first liquid outlet pipe 501 is communicated with the second end of the second liquid outlet pipe 502 through a second liquid outlet connecting pipe 504.

[0104] As an optional implementation manner, the upper end of the first liquid outlet connecting pipe 503 is higher than the height of the first liquid outlet pipe 501, and the lower end of the liquid outlet connecting pipe 503 is lower than the height of the second liquid outlet pipe 502.

[0105] It should be noted that during actual use, the first liquid outlet pipe 501 and the second liquid outlet pipe 502 can work simultaneously, or either one of them can be selected to be closed according to the requirements of specific usage scenarios. The present invention does not limit this. Usually, the first liquid outlet pipe 501 is closed and the second liquid outlet pipe 502 is opened. The second liquid outlet pipe 502 with a lower position can prevent the problem of unremoved wax being discharged together from the liquid outlet pipe 5 and blocking the liquid outlet pipe.

[0106] It should be noted that when one of the first liquid outlet pipe 501 and the second liquid outlet pipe 502 fails, the other can work as a standby liquid outlet pipe normally, avoiding the situation where the solution in the dewaxing tank 100 cannot flow out.

[0107] As an alternative embodiment, a first control valve 5011 and a second control valve 5021 are respectively provided on the first liquid outlet pipe 501 and the second liquid outlet pipe 502. It should be noted that the first control valve 5011 and the second control valve 5021 can adjust the flow rate of the solution in the first liquid outlet pipe 501 and the second liquid outlet pipe 502, and can also realize the opening and closing of the first liquid outlet pipe 501 and the second liquid outlet pipe 502. The present invention does not limit the specific functions of the first control valve 5011 and the second control valve 5021, nor is it limited to the above examples.

[0108] In order to timely recover the wax flowing out of the first wax collection pipe 212, the wax removal device further includes: a wax collection tank 4; a second wax collection pipe 213 for transporting wax is further provided at the bottom of the first wax collection tank 2 or / and the second wax collection tank 3. The second wax collection pipe 213 is communicated with the first wax collection pipe 212, and the second wax collection pipe 213 passes through the bottom of the wax removal tank body 100 to discharge the wax into the wax collection tank 4.

[0109] Wherein, a third control valve 2131 is further provided on the second wax collection pipe 213. When the third control valve 2131 is closed, the first wax collection tank 2 or / and the second wax collection tank 3 and the wax collection tank 4 are in a closed state; when the third control valve 2131 is opened, the first wax collection tank 2 or / and the second wax collection tank 3 and the wax collection tank 4 are in a communicated state. By providing the third control valve 2131 on the second wax collection pipe 213, the third control valve 2131 can be closed during wax recovery to achieve plugging, improve safety, and avoid material loss and environmental pollution.

[0110] It should be noted that the third control valve 2131 can adjust the flow rate of the solution in the second wax collection pipe 213, and can also realize the opening and closing of the second wax collection pipe 213. The present invention does not limit the specific functions of the third control valve 2131, nor is it limited to the above examples.

[0111] As Figure 9 shown, after the wax flows into the wax collection tank 4 for storage, a second exhaust port 41, a disassembly part 42 and a wax discharge assembly 43 can be further provided on the wax collection tank 4. The second exhaust port 41 can timely discharge the waste gas generated in the wax collection tank 4 after the wax flows into the wax collection tank 4. The disassembly part 42 is provided to facilitate the disassembly, maintenance and regular inspection and recovery of the wax collection tank 4. The wax discharge assembly 43 can be composed of a discharge pipe and a head. The head is of a detachable design. When the wax stored in the wax collection tank 4 is too much, the head of the wax discharge assembly 43 is opened to discharge the wax from the wax collection tank 4.

[0112] As an alternative embodiment, a mist-catching net is further disposed inside the wax-removing tank body 100. The upper end of the mist-catching net is connected to the top of the wax-removing tank body 100, and the lower end of the mist-catching net is supported and connected inside the wax-removing tank body 100 through a mounting rack.

[0113] It should be noted that the mist-catching net can be disposed at a position in the second chamber 20 close to the first partition 101, can be disposed at the position of the third partition 301 between the second chamber 20 and the fourth chamber 40, or can be disposed at the position of the second partition 201 between the fourth chamber 40 and the third chamber 30. The present invention does not limit this. Taking the mist-catching net disposed at a position in the second chamber 20 close to the first partition 101 and disposed at the position of the third partition 301 between the second chamber 20 and the fourth chamber 40 as examples, as Figure 3 and Figure 4 shown, the mist-catching net can play a role in preventing liquid from passing through, and play a role in further limiting the liquid level and buffering the chamber to make the solution flow more stably.

[0114] It should be noted that the mist-catching net refers to a vapor-liquid filter net, also called a demisting net, a demisting screen, etc., and is used for demisting various gases, filtering the mist droplets and mist foams in the gas, and realizing gas-liquid separation.

[0115] Specifically, the mist-catching net enables the air flow to pass through multiple layers of fine metal wire meshes to achieve the purpose of gas-liquid separation. Its working mechanism is that when the fine liquid mist droplets entrained in the gas phase pass through the wire mesh of the mist-catching net, the mist droplets hit the demisting filaments and are adhered or adsorbed. After multiple repeated adsorptions, the extremely small mist droplets coagulate into large droplets. Under the action of gravity, the droplets move downward along the wire diameter of the filaments, and at the same time continue to adsorb the entrained mist droplets in the gas. The coagulated and enlarged droplets flow to the bottom of the demister and drop down as liquid droplets.

[0116] In addition, in order to prevent the gas in the wax-removing tank body 100 from not flowing due to the blockage of the mist-catching net, gas communication holes are further provided on the mist-catching net. As Figure 3 shown, a first gas communication hole 2021 is provided on the first mist-catching net 202, and a second gas communication hole 2031 is provided on the second mist-catching net 203.

[0117] As an alternative embodiment, at least one sewage discharge pipe 60 is respectively disposed at the bottoms of the first chamber 10, the second chamber 20, the third chamber 30 and the fourth chamber 40 of the wax-removing tank body 100. The sewage discharge pipe 60 can be one, two or more, and the present invention does not limit this. As Figure 3 shown, one sewage discharge pipe 60 is respectively disposed at the bottoms of the first chamber 10, the second chamber 20, the third chamber 30 and the fourth chamber 40. The sewage discharge pipe 60 is used to timely discharge impurities such as iron slag and sediment deposited at the bottom of each chamber of the wax-removing tank body 100.

[0118] In addition, at least one first exhaust port 70 may be provided at the top of the wax-removing tank body 100. The first exhaust port 70 is used to timely discharge the waste gas in the wax-removing tank body 100. A manhole 80 may also be provided at the top of the wax-removing tank body 100. The manhole 80 facilitates the operator to enter and exit from the manhole 80 when the wax-removing tank body 100 is under maintenance and repair.

[0119] In addition, a plurality of pressure detection interfaces 90 may be provided at the top of the wax-removing tank body 100. The pressure detection interfaces 90 can be connected to a pressure detection device. The number of the pressure detection interfaces 90 may be one, two or more. The pressure detection device may be a pressure gauge, a pressure monitor, etc. The present embodiment does not limit the number of the pressure detection interfaces 90 provided and the specific type of the pressure detection device, nor is it limited to the above examples.

[0120] It should be noted that at least one orifice 1011 may also be provided on the first partition 101 or / and the third partition 301. Among them, at least one orifice 1011 may be provided only on the first partition 101, only on the second partition 201, or on both the first partition 101 and the third partition 301. The present invention does not limit this and can be flexibly selected according to the requirements of the actual application scenario.

[0121] Taking the first partition 101 as an example, as Figure 10 shown, an orifice 1011 is provided on the first partition 101. The orifice 1011 can be used to facilitate observation and the passage of the operator when the wax-removing device is under maintenance and repair. Specifically, the orifice 1011 can be sealed with a steel plate connected by bolts, and an oil-resistant and high-temperature-resistant sealing gasket can also be provided around the connection between the steel plate and the orifice 1011. When maintenance and repair are not carried out, the steel plate and the oil-resistant and high-temperature-resistant sealing gasket cooperate to seal the orifice 1011 to prevent the leakage of the solution.

[0122] The wax removal device provided by the present invention includes a wax removal tank body. A cavity is arranged inside the wax removal tank body.
