Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of chemical petroleum fractionation, and particularly relates to a gas-liquid separation equipment for chemical petroleum refining. BACKGROUND

[0002] Petroleum fractionation is a method for separating a mixture of several different boiling points in petroleum, which belongs to physical change. Petroleum is a mixture composed of more than 8000 different molecular size hydrocarbons (and a small amount of sulfur compounds).

[0003] Petroleum must be processed before use to produce petroleum products suitable for various purposes. The common processing method is fractionation, which separates hydrocarbons in petroleum according to different molecular sizes and boiling points, and then uses chemical processing methods to improve the value of the products.

[0004] In the prior art, a technical scheme of a chemical petroleum fractionation treatment device is also provided. For example, a chemical petroleum refining reaction kettle is disclosed in a Chinese patent with the publication number CN211864945U, which comprises a crude oil refining bin. The crude oil refining bin is movably connected with a movable roller shaft on one side. The inner side of the movable roller shaft is embedded with a damping block. The other side of the crude oil refining bin is welded with a cooling channel. The inner wall of the cooling channel is clamped with a micron filter screen. The bottom of the cooling channel is fixedly provided with a waste residue accumulation chamber in the middle. The device is provided with a separation chamber and a collection chamber. When the mixture of petroleum enters the separation chamber from the cooling channel, the outer wall of the separation chamber will generate different high temperatures due to the action of the resistor. Different boiling point petroleum is separated according to the different boiling points. This method can obtain relatively pure liquefied gas. Then, some organic matter with low boiling points is separated. The petroleum that is not distilled away flows away through the total valve. Although the reaction kettle is set in this way to better separate liquefied gas, petroleum and residues with different boiling points, the device needs to heat the crude oil for a long time before distillation, which greatly slows down the distillation rate of the crude oil. Moreover, the device cannot completely separate the crude oil at the bottom of the reaction kettle, and various oils are mixed, which needs to be distilled repeatedly.

[0005] Most of the chemical petroleum fractionation devices currently used in the prior art in the process of distilling crude oil, by external heating of crude oil, and then transporting the crude oil into the distillation column, but in the process of transporting crude oil into the distillation column, the heat loss of the crude oil will occur, which will result in insufficient distillation of the crude oil, greatly slowing down the distillation rate of the crude oil, and when distilling the crude oil, the petroleum vapor cannot flow away from the oil pipeline in time after condensing into liquid fraction, and a small amount of petroleum vapor will continue to rise in the fractionating column due to insufficient condensation during the rising process, causing the fractionated petroleum vapor to condense at another height, resulting in low quality of the obtained oil product, and the crude oil is not completely separated by distillation at the bottom of the distillation column, various oils are mixed, and repeated distillation is required. SUMMARY

[0006] In order to make up for the shortcomings of the prior art, solve the problem that the chemical petroleum fractionation device needs to heat the crude oil for a long time before distilling the crude oil, greatly slows down the distillation rate of the crude oil, and the heat loss of the crude oil occurs during the process of entering the distillation column, resulting in a decrease in the heat of the oil entering the column, causing the heating pressure of the internal heating wire to be high, causing resource waste, when distilling the crude oil, the petroleum vapor cannot flow away from the oil pipeline in time after condensing into liquid fraction, and a small amount of petroleum vapor will continue to rise in the fractionating column due to insufficient condensation during the rising process, causing the fractionated petroleum vapor to condense at another height, resulting in low quality of the obtained oil product, and the crude oil is not completely separated by distillation at the bottom of the distillation column, various oils are mixed, and repeated distillation is required, the present application provides a gas-liquid separation equipment for chemical petroleum refining.

[0007] The technical solution adopted by this invention to solve its technical problem is as follows: A gas-liquid separation device for chemical petroleum refining, comprising a shell, a support, a fractionation mechanism, and a controller; the shell is cylindrical in the middle and semi-circular at both ends; the shell is hollow; the support is located near the bottom of the shell and is fixedly connected to it; the fractionation mechanism is installed inside the shell; the upper and lower ends of the shell are respectively connected to a gas outlet pipe and an oil outlet pipe; an oil inlet pipe is provided on the side wall of the shell near the gas outlet pipe; one end of the oil inlet pipe connects to the lower interior of the shell, and the other end connects to an external oil valve; a uniformly arranged diversion mechanism is provided in the inner wall of the shell cavity; the fractionation mechanism includes an oil collecting plate, a first oil supply pipe, and a second oil supply pipe; the oil collecting plate is hemispherical and hollow inside; the diameter of the oil collecting plate is smaller than the inner diameter of the shell; the oil collecting... The plate is fixedly connected to the inner wall of the shell via an extension plate; the extension plate is located above the oil collecting plate; the first oil supply pipe is connected to the lower center of the oil collecting plate; one end of the second oil supply pipe is connected to the first oil supply pipe, and the other end is connected to the corresponding external oil outlet valve; a main valve is fixedly connected to the upper part of the inner wall of the oil outlet pipe; multiple thermometers are fixedly connected to the side of the shell away from the oil inlet pipe and the lower part of the side wall of the shell away from the oil inlet pipe, and the thermometers on the side of the shell away from the oil inlet pipe are parallel to the lower part of the corresponding oil collecting plate; a resistance wire is fixedly connected to the lower part of the shell and the periphery of the oil inlet pipe; a first baffle is provided on the lower surface of the shell near the oil inlet pipe; the upper part of the first baffle is parallel to the oil inlet pipe; multiple heating filters are uniformly fixedly connected to the side of the first baffle away from the oil inlet pipe; the other end of the heating filter is fixedly connected to the side wall of the shell; the heating filter and the resistance wire are controlled by a controller; the shell is wrapped with an insulation layer.

[0008] During operation, the top-pulled oil enters the space near the inlet pipe of the first baffle. Since the unheated top-pulled oil needs prolonged heating after entering the fractionation tower, the controller heats the resistance wires around the inlet pipe and the lower part of the shell, as well as the multi-layer heating filter fixed to the bottom of the shell, before the oil is delivered to the lower part of the shell. The temperature of the multi-layer heating filter at the bottom of the shell is maintained at 400℃-500℃ by observing the temperature gauge at the bottom of the shell. When the space near the inlet pipe of the first baffle is full, the controller stops the resistance wires around the inlet pipe. This effectively prevents the top-pulled oil from being unable to fractionate due to excessively high temperatures above the shell. At this point, the top-pulled oil enters the upper surface of the first layer of heating filter on the side of the first baffle away from the inlet pipe. The multi-layer heating filter ensures that the top-pulled oil is heated evenly at the bottom of the shell, preventing uneven heating in the middle and thus reducing resource waste and improving utilization. Furthermore, the bottom of the shell is heated... The remaining oil is heavy oil, which is relatively pure after being heated by a multi-layer heating filter. The controller controls the resistance wire at the bottom of the shell to generate a high temperature of 400℃-500℃, which distills the top-distilled oil into steam. Based on their different boiling points, the top-distilled oil is separated. Because the temperature gradually decreases from bottom to top inside the shell, the steam of the top-distilled oil with a higher boiling point enters the space on the upper surface of the lower oil collecting plate. During the upward movement of the steam, different components in the top-distilled oil will condense into liquid at different heights in the tower and drip into different oil collecting plates. Then, it is transported to the outside through the first oil delivery pipe corresponding to the different oil collecting plates and into the second oil delivery pipe. Then, it is transported to the outside through the first oil delivery pipe at the top and into the second oil delivery pipe. The petroleum gas with a lower boiling point is transported to the outside through the upper gas outlet pipe. The heavy oil at the bottom of the shell flows away through the main valve. After this fractionation is completed, the next fractionation can be carried out, which effectively improves the fractionation efficiency. In addition, the outer layer of the shell is wrapped with a heat insulation layer, which effectively reduces the heat loss of the shell and reduces resource waste.

[0009] Preferably, each of the second oil pipes has a plurality of through holes evenly formed above it; a plurality of support rods are evenly fixed to the periphery above the through holes of the second oil pipe; and a cap is fixed to the top of each support rod.

[0010] During operation, the liquid flowing into the lower second oil pipe is reheated to generate steam due to the decreasing temperature inside the casing from bottom to top. The steam generated in the second oil pipe flows out through the through hole to the area between the lower surface of the middle oil collecting plate and the upper surface of the lower oil collecting plate. The steam condenses on the lower surface of the middle oil collecting plate and drips downwards. The cap at the bottom of the middle section prevents the dripping liquid from dripping into the middle second oil pipe through the through hole, thus preventing the mixing of multiple liquids. This effectively prevents the mixing of oil products with different boiling points, improves the quality of oil products, speeds up the production rate of oil products, and results in relatively pure oil products.

[0011] Preferably, a power distribution box is fixedly connected to the lower part of one side of the first baffle of the housing; a power-conducting block is fixedly connected to the center of the bottom of the power distribution box; the upper surface of the power-conducting block is concave; a slider is provided above the power-conducting block; the slider is elastically connected to the bottom of the power distribution box by a spring; an insert is fixedly connected to the middle of the slider; one end of the insert is connected to the inside of the housing, and the other end extends out of the lower surface of the slider, and the insert is positioned inside the power distribution box corresponding to the upper surface of the power-conducting block; the power-conducting block is electrically connected to the main valve by a wire.

[0012] During operation, when the heavy oil flowing into the bottom of the housing reaches a certain level, it begins to squeeze the insert block. Due to the pressure of the heavy oil, the insert block moves the slider towards the lower end of the distribution box. At this time, the spring is compressed. When the heavy oil causes the insert block to contact the energized block, the energized block is energized. At this time, the main control valve opens and the heavy oil is discharged. As the heavy oil at the bottom of the housing decreases, the insert block moves away from the energized block. At this time, the energized block is de-energized, the spring returns to its original position, and the main valve closes. This ensures that the heavy oil at the bottom of the housing is always discharged, preventing the top oil from mixing with the heavy oil during the next oil intake, which would require redistillation and effectively reduce resource waste.

[0013] Preferably, the housing is fixedly connected to a second baffle above each oil collecting plate; the lower end of the second baffle is designed to slope downwards towards the middle of the oil collecting plate; the cross-section of the second baffle is designed with an inverted hook shape.

[0014] During operation, the resistance wire inside the shell operates at a high temperature of 400℃-500℃, separating the top-lifting oils with different boiling points. This causes the vapors of the top-lifting oils with different boiling points to rise inside the shell. As the vapors rise, they condense on the lower surface of the second baffle. Due to the hook-shaped design of the second baffle's cross-section, the condensed oil products can be collected within the space formed by the hooks. Furthermore, because the temperature inside the shell gradually decreases from bottom to top, the condensed oil products turn back into vapor and continue to rise. This effectively prevents the condensed oil products from dripping onto the upper surface of the oil collecting plate with the oil products collected on the corresponding oil collecting plate, thus effectively improving the quality of each oil product. In addition, the second baffle above each oil collecting plate is inclined downwards towards the middle of each oil collecting plate, causing the vapor to first gather in the upper space of the lower oil collecting plate, and then condense on the lower surface of the upper oil collecting plate. This effectively prevents the vapor from directly entering higher positions inside the shell, thus effectively preventing the same oil product from condensing on different lower surfaces of the oil collecting plates, thereby improving the quality of the oil products and the production rate.

[0015] Preferably, each of the second baffles has multiple grooves on the surface near the corresponding oil collecting plate.

[0016] During operation, the oil products that condense on the surface of the second baffle near the oil collecting plate flow into the hook-shaped space below the second baffle through the groove. This effectively increases the rate at which the condensed oil products flow into the hook-shaped space below the second baffle, preventing the condensed oil products from dripping directly onto the upper surface of the oil collecting plate or directly into the lower space inside the shell. This effectively prevents the mixing of various oil products and improves the purity of the oil products.

[0017] Preferably, a plurality of uniformly arranged first locking blocks are fixedly connected to the lower surface of the plurality of oil collecting plates; the lower end of the first locking blocks is designed with a pointed tip; a plurality of uniformly arranged second locking blocks are fixedly connected to the upper part of the inner wall of the first oil delivery pipe; the plurality of second locking blocks are inclined downward towards the middle of the first oil delivery pipe; the other ends of the plurality of second locking blocks are connected to each other; and the other ends of the plurality of second locking blocks are fixedly connected to the first locking blocks.

[0018] During operation, steam condenses on the lower surface of the oil collecting plate, and the resulting oil product drips down to the upper surface of the lower oil collecting plate via the first clamping block. The oil product on the upper surface of the lower oil collecting plate flows to the bottom of the lower oil collecting plate and then drips into the first oil conveying pipe through the second clamping block and the first clamping block. This effectively increases the transport speed of the oil product and prevents the oil product from accumulating on the surface of the oil collecting plate, thereby effectively increasing the production rate of the oil product.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. The gas-liquid separation equipment for chemical petroleum refining described in this invention can remove oil products that do not belong to the oil collecting plate by setting through holes and caps. The caps prevent dripping oil products from dripping into the second oil conveying pipe through the through holes, so that one type of oil product can be mixed with another type of oil product. This effectively avoids the mixing of oil products with different boiling points, improves the quality of oil products, and accelerates the production rate of oil products.

[0021] 2. The gas-liquid separation equipment for chemical and petroleum refining described in this invention, by setting a second baffle, enables the steam to condense on the lower surface of the second baffle during its ascent. Due to the hook-shaped design of the cross-section of the second baffle, different condensed oil products can be collected. Furthermore, because the internal temperature of the shell gradually decreases from bottom to top, the condensed oil products turn back into steam and continue to rise. This effectively prevents the condensed oil products from dripping onto the upper surface of the oil collecting plate along with the lower end of the second baffle, thus avoiding mixing with the oil products collected by the corresponding oil collecting plate, thereby effectively improving the quality of each oil product.

[0022] 3. The gas-liquid separation equipment for chemical and petroleum refining described in this invention enables vapor to condense on the lower surface of the oil collecting plate by setting a first clamping block and a second clamping block. The oil product generated by condensation drips down with the first clamping block to the upper surface of the lower oil collecting plate. The oil product on the upper surface of the lower oil collecting plate flows to the bottom of the lower oil collecting plate and then drips into the first oil conveying pipe through the second clamping block and the first clamping block. This effectively improves the transportation speed of the oil product and avoids the accumulation of oil product on the surface of the oil collecting plate, thereby effectively improving the production rate of oil product.

Detailed Implementation

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] like Figures 1 to 6 As shown, the gas-liquid separation equipment for chemical petroleum refining of the present invention includes a shell 1, a support 2, a fractionation mechanism, and a controller; the shell 1 is cylindrical in the middle and semi-circular at both ends; the shell 1 is hollow inside; the support 2 is located near the bottom of the shell 1 and is fixedly connected to the shell 1; the fractionation mechanism is installed inside the shell 1; the upper and lower ends of the shell 1 are respectively connected to a gas outlet pipe 11 and an oil outlet pipe 12; an oil inlet pipe 13 is provided on the side wall of the shell 1 near the gas outlet pipe 11; one end of the oil inlet pipe 13 is connected to the lower interior of the shell 1, and the other end is connected to an external oil supply valve 14; a uniformly arranged diversion mechanism is provided in the cavity inside the shell 1; the fractionation mechanism includes an oil collecting plate 15, a first oil supply pipe 16, and a second oil supply pipe 17; the oil collecting plate 15 is hemispherical and hollow inside; the diameter of the oil collecting plate 15 is smaller than the inner diameter of the shell 1; the oil collecting plate 15 is fixedly connected to the inner wall of the shell 1 through an extension plate 18; the extension plate 15 is hollow inside; the oil collecting plate 15 is located near the bottom of the shell 1 and ...7; the extension plate 15 is hollow inside; the oil collecting plate 15 is located near the bottom of the shell 1 and is fixedly connected to the inner wall of the shell 1 through an extension The outlet plate 18 is located above the oil collection plate 15; the first oil supply pipe 16 is connected to the lower middle part of the oil collection plate 15; one end of the second oil supply pipe 17 is connected to the first oil supply pipe 16, and the other end is connected to the corresponding external oil outlet valve 19; a main valve 21 is fixedly connected to the upper part of the inner wall of the oil outlet pipe 12; multiple thermometers 22 are fixedly connected to the side of the housing 1 away from the oil inlet pipe 13 and the lower part of the side wall of the housing 1 away from the oil inlet pipe 13, and the thermometers 22 on the side of the housing 1 away from the oil inlet pipe 13 are connected to the corresponding oil collection plate. 15 is parallel to the bottom; a resistance wire is fixedly connected to the lower part of the inside of the housing 1 and the periphery of the oil inlet pipe 13; a first baffle 26 is provided on the lower surface of the inside of the housing 1 near the oil inlet pipe 13; the upper end of the first baffle 26 is parallel to the oil inlet pipe 13; a plurality of heating filters 27 are uniformly fixedly connected to the side of the first baffle 26 away from the oil inlet pipe 13; the other end of the heating filter 27 is fixedly connected to the side wall of the housing; the heating filter 27 and the resistance wire are controlled by a controller; the outside of the housing 1 is wrapped with a heat insulation layer 3.

[0033] During operation, the top-pulling oil enters the space near the first baffle 26 through the oil inlet pipe 13. Since the unheated top-pulling oil needs prolonged heating after entering the fractionation tower, the controller controls the resistance wires around the oil inlet pipe 13 and the lower periphery of the shell 1, as well as the multi-layer heating filter 27 fixed to the bottom of the shell 1, to heat the oil before it is delivered to the lower interior of the shell 1. The temperature of the multi-layer heating filter 27 at the bottom of the shell 1 is fixed at 400℃-500℃ by the thermometer 22 at the bottom of the shell 1. Once the first baffle 26 approaches the oil inlet pipe 13... When one side of the space is full of oil, the controller stops the resistance wire around the oil inlet pipe 13. This effectively prevents the top-distilled oil from being unable to be effectively fractionated due to excessively high temperatures above the casing 1. At this time, the top-distilled oil enters the upper surface of the first layer of heating filter 27 on the side of the first baffle 26 away from the oil inlet pipe 13. Because of the multi-layer heating filter 27, the top-distilled oil can be evenly heated at the bottom of the casing 1, preventing uneven heating in the middle part of the oil and thus avoiding low utilization of the top-distilled oil, reducing resource waste, and ensuring the casing 1... The oil remaining at the bottom after heating is heavy oil. Heating through multiple layers of heating filter 27 yields relatively pure heavy oil. The controller operates the resistance wire at the bottom of the shell 1 to generate a high temperature of 400℃-500℃, distilling the top-pulling oil into steam. Based on their boiling points, top-pulling oils with different boiling points are separated. Because the temperature gradually decreases from bottom to top inside the shell 1, the higher-boiling-point top-pulling oil vapor enters the space above the lower oil collecting plate 15. During the upward movement of the vapor, different components in the top-pulling oil condense at different heights within the tower, forming a liquid. The oil drips into different oil collecting plates 15; then it enters the second oil collecting pipe 17 through the first oil collecting pipe 16 corresponding to the different oil collecting plates 15 and is transported to the outside; then it enters the second oil collecting pipe 17 through the upper first oil collecting pipe 16 and is transported to the outside. The low-boiling-point petroleum gas is transported to the outside through the upper gas outlet pipe 11. The heavy oil at the bottom of the shell 1 flows away through the main valve 21. After this fractionation is completed, the next fractionation can be carried out, which effectively improves the fractionation efficiency. In addition, the outer layer of the shell 1 is wrapped with a heat insulation layer 3, which effectively reduces the heat loss of the shell 1 and reduces resource waste.

[0034] In one embodiment of the present invention, a plurality of through holes 23 are uniformly opened above each of the second oil pipes 17; a plurality of support rods 24 are uniformly fixed to the periphery above the through holes 23 of the second oil pipes 17; and a cap 25 is fixed to the top of the support rods 24.

[0035] During operation, the liquid flowing into the lower second oil pipe 17 is reheated to generate steam due to the decreasing temperature inside the shell 1 from bottom to top. The steam generated in the second oil pipe 17 is then released through the through hole 23 between the lower surface of the middle oil collecting plate 15 and the upper surface of the lower oil collecting plate 15. The steam condenses on the lower surface of the middle oil collecting plate 15 and drips downwards. The cap 25 at the bottom of the middle section prevents the dripping liquid from dripping into the middle second oil pipe 17 through the through hole 23, thus preventing the mixing of multiple liquids. This effectively prevents the mixing of oil products with different boiling points, improves the quality of oil products, accelerates the production rate of oil products, and results in relatively pure oil products.

[0036] In one embodiment of the present invention, a power distribution box 28 is fixedly connected to the lower side of the first baffle 26 of the housing 1; a power-conducting block 29 is fixedly connected to the center of the bottom of the power distribution box 28; the upper surface of the power-conducting block 29 is concave; a slider 31 is provided above the power-conducting block 29; the slider 31 is elastically connected to the bottom of the power distribution box 28 by a spring 32; an insert 33 is fixedly connected to the middle of the slider 31; one end of the insert 33 is connected to the inside of the housing 1, and the other end extends out of the lower surface of the slider 31, and the insert 33 is correspondingly arranged inside the power distribution box 28 with the upper surface of the power-conducting block 29; the power-conducting block 29 is electrically connected to the main valve 21 by a wire.

[0037] During operation, when the heavy oil flowing into the bottom of the housing 1 reaches a certain level and begins to squeeze the insert 33, the insert 33, due to the pressure of the heavy oil, drives the slider 31 to move towards the lower end of the distribution box 28. At this time, the spring 32 is compressed. When the heavy oil causes the insert 33 to contact the energized block 29, the energized block 29 is energized. At this time, the control valve 21 opens and discharges the heavy oil. As the heavy oil at the bottom of the housing 1 decreases, the insert 33 moves away from the energized block 29. At this time, the energized block 29 is de-energized, the spring 32 returns to its original position, and the main valve 21 closes, so that the heavy oil at the bottom of the housing 1 is always discharged. This avoids the situation where the heavy oil is not discharged in time during the next oil intake, causing the top oil to mix with the heavy oil and requiring re-distillation, effectively reducing resource waste.

[0038] In one embodiment of the present invention, the housing 1 is fixedly connected to a second baffle 34 above each oil collecting plate 15; the lower end of the second baffle 34 is designed to be inclined towards the lower center of the oil collecting plate 15; the cross-section of the second baffle 34 is designed with an inverted hook shape.

[0039] During operation, the resistance wire inside the lower part of the casing 1 operates at a high temperature of 400℃-500℃, separating the top-lifting oils with different boiling points. This causes the vapors of the top-lifting oils with different boiling points to rise inside the casing 1. As the vapors rise, they condense on the lower surface of the second baffle 34. Due to the hook-shaped design of the cross-section of the second baffle 34, the condensed oil products can be collected within the space formed by the hooks. Furthermore, because the temperature inside the casing 1 gradually decreases from bottom to top, the condensed oil products turn back into vapor and continue to rise, effectively preventing the condensed oil products from being carried away by the second baffle. The lower end of the baffle 34 drips onto the upper surface of the oil collecting plate 15, mixing with the oil products collected by the corresponding oil collecting plate 15, thereby effectively improving the quality of each oil product. Furthermore, the second baffle 34 above each oil collecting plate 15 is inclined downwards towards the middle of each oil collecting plate 15, causing the vapor to first gather in the upper space of the upper surface of the lower oil collecting plate 15, and then the vapor condenses on the lower surface of the upper oil collecting plate 15. This effectively prevents the vapor from directly entering the higher position inside the shell 1, thereby effectively preventing the same oil product from condensing on the lower surface of different oil collecting plates 15, thus improving the quality of the oil products and the production rate.

[0040] In one embodiment of the present invention, each of the second baffles 34 has a plurality of grooves 3401 on the surface near the corresponding oil collecting plate 15.

[0041] During operation, the oil products that condense on the surface of the second baffle 34 near the oil collecting plate 15 flow into the hook-shaped space below the second baffle 34 through the groove 3401. This can effectively increase the rate at which the condensed oil products flow into the hook-shaped space below the second baffle 34, and prevent the condensed oil products from dripping directly onto the upper surface of the oil collecting plate 15 or directly into the lower space inside the shell 1. This effectively avoids the mixing of various oil products and improves the purity of the oil products.

[0042] In one embodiment of the present invention, a plurality of uniformly arranged first locking blocks 35 are fixedly connected to the lower surface of a plurality of oil collecting plates 15; the lower end of the first locking blocks 35 is designed with a pointed tip; a plurality of uniformly arranged second locking blocks 36 are fixedly connected to the upper part of the inner wall of the first oil delivery pipe 16; the plurality of second locking blocks 36 are inclined downward towards the middle of the first oil delivery pipe 16; the other ends of the plurality of second locking blocks 36 are connected to each other; the other ends of the plurality of second locking blocks 36 are fixedly connected to the first locking blocks 35.

[0043] During operation, steam condenses on the lower surface of the oil collecting plate 15. The resulting oil product drips down the first clamping block 35 to the upper surface of the lower oil collecting plate 15. The oil product on the upper surface of the lower oil collecting plate 15 flows to the bottom of the lower oil collecting plate 15 and then drips into the first oil conveying pipe 16 through the second clamping block 36 and the first clamping block 35. This effectively increases the transport speed of the oil product and prevents the oil product from accumulating on the surface of the oil collecting plate 15, thereby effectively increasing the production rate of the oil product. Detailed implementation method:

[0045] During operation, the top-pulling oil enters the space near the first baffle 26 through the oil inlet pipe 13. Since the unheated top-pulling oil needs prolonged heating after entering the fractionation tower, the controller controls the resistance wires around the oil inlet pipe 13 and the lower periphery of the shell 1, as well as the multi-layer heating filter 27 fixed to the bottom of the shell 1, to heat the oil before it is delivered to the lower interior of the shell 1. The temperature of the multi-layer heating filter 27 at the bottom of the shell 1 is fixed at 400℃-500℃ by the thermometer 22 at the bottom of the shell 1. Once the space near the oil inlet pipe 13 of the first baffle 26 is full, the controller controls the heating wires around the oil inlet pipe 13. When the resistance wire stops working, the resistance wire around the oil inlet pipe 13 stops working, effectively preventing the top-pulling oil from being unable to be effectively fractionated due to excessively high temperature above the housing 1. At this time, the top-pulling oil enters the upper surface of the first layer of heating filter 27 on the side of the first baffle 26 away from the oil inlet pipe 13. Due to the multi-layer heating filter 27, the top-pulling oil can be evenly heated at the bottom of the housing 1, avoiding uneven heating in the middle part of the top-pulling oil, thus avoiding low utilization rate of the top-pulling oil and reducing resource waste. Moreover, the oil left at the bottom of the housing 1 after heating is heavy oil, and the heavy oil obtained after heating by the multi-layer heating filter 27 is relatively pure. The controller controls the housing 1 The lower internal resistance wire generates a high temperature of 400℃-500℃, distilling the top-drawing oil into vapor. Based on their different boiling points, the top-drawing oils are separated. Because the temperature gradually decreases from bottom to top inside the shell 1, the higher-boiling-point top-drawing oil vapor enters the space above the lower oil collecting plate 15. During the upward movement of the vapor, different components in the top-drawing oil condense at different heights within the tower, forming liquids that drip into different oil collecting plates 15. Subsequently, the liquid flows through the first oil delivery pipe 16 corresponding to each oil collecting plate 15 into the second oil delivery pipe 17 and is transported to the outside. The liquid flowing into the lower second oil delivery pipe 17... Because the internal temperature of the shell 1 decreases from bottom to top, the liquid condensed inside the second oil pipe 17 is reheated to generate steam. The secondary steam flows out through the through hole 23 to the space between the lower surface of the middle oil collecting plate 15 and the upper surface of the lower oil collecting plate 15. The steam condenses on the lower surface of the middle oil collecting plate 15 and drips downwards. The cap 25 at the bottom of the middle prevents the dripping liquid from dripping into the second oil pipe 17 in the middle through the through hole 23, thus preventing the mixing of multiple liquids. This effectively prevents the mixing of oil products with different boiling points, improves the quality of oil products, speeds up the production rate of oil products, and results in relatively pure oil products.

[0046] When the heavy oil flowing into the bottom of the housing 1 reaches a certain level, it begins to squeeze the insert 33. Due to the pressure of the heavy oil, the insert 33 drives the slider 31 to move towards the lower end of the distribution box 28. At this time, the spring 32 is compressed. When the heavy oil causes the insert 33 to contact the energized block 29, the energized block 29 is energized. At this time, the control valve 21 opens and discharges the heavy oil. As the heavy oil at the bottom of the housing 1 decreases, the insert 33 moves away from the energized block 29. At this time, the energized block 29 is de-energized, the spring 32 returns to its original position, and the main valve 21 closes. This ensures that the heavy oil at the bottom of the housing 1 is always discharged, preventing the heavy oil from not being discharged in time during the next oil intake, which would cause the top oil to mix with the heavy oil and require re-distillation, effectively reducing resource waste.

[0047] Inside the casing 1, the resistance wire operates at a high temperature of 400℃-500℃, separating the top-lifting oils with different boiling points. This causes the vapors of the top-lifting oils with different boiling points to rise inside the casing 1. During this rise, the vapors condense on the lower surface of the second baffle 34. Due to the hook-shaped design of the second baffle 34's cross-section, the condensed oil products can be collected within the space created by the hooks. Furthermore, because the temperature inside the casing 1 gradually decreases from bottom to top, the condensed oil products condense back into vapor and continue to rise. This effectively prevents the condensed oil products from dripping onto the upper surface of the oil collecting plate 15 with the oil products collected on the corresponding oil collecting plate 15, thus effectively improving the quality of each oil product. Additionally, the second baffle 34 above each oil collecting plate 15 is inclined downwards towards the middle of each oil collecting plate 15, causing the vapor to first converge in the upper space of the lower oil collecting plate 15, and then condense on the lower surface of the upper oil collecting plate 15, effectively preventing the vapor from directly entering the upper surface. The higher position inside the shell 1 effectively prevents the same oil product from condensing on different lower surfaces of the oil collecting plates 15. The vapor condenses on the lower surface of the oil collecting plates 15, and the resulting oil product drips down with the first clamping block 35 to the upper surface of the lower oil collecting plate 15. The oil product on the upper surface of the lower oil collecting plate 15 flows to the bottom of the lower oil collecting plate 15 and then drips into the first oil delivery pipe 16 via the second clamping block 36 and the first clamping block 35. This effectively increases the transport speed of the oil product and prevents the oil product from accumulating on the surface of the oil collecting plates 15, thereby effectively increasing the production rate of the oil product. Simultaneously, oil product condensed on the surface of the second baffle 34 near the oil collecting plate 15 flows through the groove 3401 into the hook-shaped space below the second baffle 34. This effectively increases the rate at which the condensed oil product flows into the hook-shaped space below the second baffle 34, preventing the condensed oil product from dripping directly onto the upper surface of the oil collecting plate 15 or directly into the lower space inside the shell 1, effectively preventing the mixing of various oil products and improving the purity of the oil product.
