Description

Technical Field

[0001] The present invention relates to the technical field of methanol production, and specifically refers to an extraction device for methanol production. Background Art

[0002] During the methanol production process, the mixing uniformity of raw materials, evaporation efficiency, and gas-liquid separation effect directly affect product purity and energy consumption. Traditional extraction devices have the following technical bottlenecks: 1. Poor coordination between stirring and heating: Conventional stirring devices adopt a single rotation speed mode and cannot dynamically adjust the stirring intensity according to the viscosity of the material and the evaporation stage, resulting in sedimentation of bottom materials, local overheating and coking, and reducing heat transfer efficiency; 2. Incomplete gas-liquid separation: Existing separation components mostly adopt single-stage condensation, and volatile substances are easily entrained with uncondensed gas phase, resulting in a decrease in methanol recovery rate; 3. High redundancy of the drive system: Multiple motors drive the stirring and transmission mechanisms, resulting in high energy consumption, large space occupation, and lag in speed regulation response; 4. Complexity of equipment maintenance: Traditional scraping mechanisms and condensation components are mostly fixed designs, which are difficult to clean and affect the continuous production cycle.

DETAILED DESCRIPTION

[0026] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0027] Combined with Figure 1 , Attachment Figure 2 , Attachment Figure 7 and attached Figure 8 : An extraction device for methanol production, which includes a power base 1. An evaporation stirring cylinder 2 is provided on the power base 1. A gas-liquid separation component 3 is provided on the evaporation stirring cylinder 2. The gas-liquid separation component 3 includes a cover body 301 that cooperates with the evaporation stirring cylinder 2. Two symmetrically distributed ventilation holes 302 are provided on the cover body 301. An intake U-shaped pipe 303 that communicates with the ventilation holes 302 is provided on the cover body 301. On both sides of the top of the intake U-shaped pipe 303, there are L-shaped condensate pipes 304 that communicate with the intake U-shaped pipe 303. A straight pipe 305 is detachably connected between the L-shaped condensate pipe 304 and the cover body 301. The straight pipe 305 is sleeved with the L-shaped condensate pipe 304, and the inner diameter of the straight pipe 305 is larger than that of the L-shaped condensate pipe 304. A condensate accumulation pipe 306 that communicates with the two L-shaped condensate pipes 304 is provided at the bottom of the cover body 301. A blower 308 is provided at both ends of the intake U-shaped pipe 303; A detachable liquid outlet door 307 is provided at the bottom of the condensate accumulation pipe 306; With this structure, the intake U-shaped pipe 303 and the double L-shaped condensate pipes 304 form a three-stage condensation path: when the evaporation gas is pushed by the blower 308 into the intake U-shaped pipe 303, primary condensation is first completed at the bottom of the intake U-shaped pipe 303. The uncondensed gas enters the two side L-shaped condensate pipes 304 under the pressure of the blower for secondary condensation, and finally, the depth separation is completed by expanding the condensation contact area through the straight pipe 305. The detachable straight pipe design is convenient for cleaning the crystallized substances. The condensate accumulation pipe 306 collects the condensate uniformly, and the liquid outlet door 307 can drain the liquid regularly without interrupting production, improving the efficiency compared with the traditional single-stage condensation.

[0028] Combined with attached Figure 1 、attached Figure 3 、attached Figure 7 、attached Figure 9 and attached Figure 10 : A condenser 4 is also provided on the evaporation stirring cylinder 2. The condenser 4 includes a cylindrical frame 406 detachably installed on the cover body 301. Heat dissipation fins 403 are provided on the cylindrical frame 406. A heat conduction pipe 401 is provided at the bottom of the heat dissipation fins 403. A spiral heat conduction pipe 402 is sleeved outside the heat conduction pipe 401. The heat conduction pipe 401 and the spiral heat conduction pipe 402 extend into the condensate accumulation pipe 306. A blower 405 is provided at the top of the heat dissipation fins 403; The blower 405 is located below the intake U-shaped pipe 303 and between the two L-shaped condensate pipes 304; With this structure, the spiral heat-conducting tube 402 is nested on the outer wall of the straight tube 305 to form a double-channel heat exchange: the inner layer releases heat through the condensation of methanol vapor, and the outer layer conducts the waste heat to the radiator 403 through the heat-conducting tube 401. The fan 405 forms an up-and-down convection to enhance heat dissipation. Tests show that this structure increases the condensation temperature difference from 15°C in the traditional design to 22°C, and the spiral structure extends the air flow residence time by 0.8 seconds to ensure the full condensation of low-boiling substances.

[0029] Combined with attached Figure 1 、attached Figure 2 、attached Figure 4 、attached Figure 5 and attached Figure 6 : An evaporation stirring device 6 for fully mixing and heating and evaporating raw materials is provided in the evaporation stirring cylinder 2. The evaporation stirring device 6 includes a circular tray 601 rotatable at the bottom of the evaporation stirring cylinder 2. A number of evenly distributed evaporation heaters 602 are provided on the circular tray 601. At the central axis of the circular tray 601, there is a main stirring impeller 603 that rotates relative to the circular tray 601 and moves up and down. Two symmetrically distributed spiral stirring wheels 604 for liquid lifting are provided on the circular tray 601. Two symmetrically distributed scraping frames 605 are fixedly installed on the circular tray 601, and the scraping frames 605 are in contact with the inner wall of the evaporation stirring cylinder 2. With this structure, the main stirring impeller 603 and the spiral stirring wheel 604 form a differential stirring field: when the circular tray 601 rotates at a speed of ω1, the spiral stirring wheel 604 vertically lifts the bottom materials at a speed of ω1 + Δω. With the radial shearing action of the scraping frame 605, the materials are evenly heated by the evaporation heaters 602 during the radial reciprocating movement.

[0030] Combined with attached Figure 1 、attached Figure 2 、attached Figure 4 、attached Figure 5 and attached Figure 6 : A double-layer transmission assembly 5 for changing the operating speed of the evaporation stirring device 6 is provided in the power base 1. The double-layer transmission assembly 5 includes a three-axis bracket 501 located in the power base 1. The three-axis bracket 501 can be driven to rotate in the power base 1 by a motor. First double-layer gear sets 502 fixedly connected to the spiral stirring wheels 604 are rotatably connected to both ends of the three-axis bracket 501. A main shaft 504 is fixedly connected to the three-axis bracket 501. A second double-layer gear set 503 located below the circular tray 601 is sleeved on the main shaft 504. The main stirring impeller 603 can move up and down on the main shaft 504 and is fixedly connected to the second double-layer gear set 503. The first double-layer gear set 502 includes a shaft body 5023 rotatably connected to the end of the three-axis bracket 501. The shaft body 5023 is fixedly connected with a first upper-layer gear 5022 and a first lower-layer gear 5021 in sequence from top to bottom. The second double-layer gear set 503 includes a sleeve body 5033 slidably connected to the main shaft 504 up and down. The sleeve body 5033 is fixedly connected with a second upper-layer gear 5032 and a second lower-layer gear 5031 in sequence from top to bottom. The distance between the first upper-layer gear 5022 and the first lower-layer gear 5021 is larger than the distance between the second upper-layer gear 5032 and the second lower-layer gear 5031. The sleeve body 5033 can slide up and down in the circular tray 601, and the sleeve body 5033 is fixedly connected with the main stirring impeller 603; A plate body 607 that can move up and down on the main shaft 504 is provided at the top of the main stirring impeller 603. The plate body 607 can drive the second double-layer gear set 503 to move up and down through the main stirring impeller 603. A control assembly 606 for controlling the lifting of the plate body 607 is provided between the plate body 607 and the evaporation stirring cylinder 2; In order to enable the first double-layer gear set 502 to rotate around the second double-layer gear set 503 while also being able to rotate on its own, as shown in the attached Figure 2 , an internal gear ring meshing with the first lower-layer gear 5021 is provided on the inner wall of the power base 1. At this time, when the three-axis bracket 501 rotates, it can drive the first double-layer gear set 502 to revolve. Since the first lower-layer gear 5021 meshes with the internal gear ring, the first lower-layer gear 5021 will roll on the internal gear ring at this time, that is, the first lower-layer gear 5021 can rotate on its own, and the rotation direction is opposite to the rotation direction of the three-axis bracket 501. At this time, the first double-layer gear set 502 can drive the second double-layer gear set 503 to rotate; Through this structure, when the second double-layer gear set 503 moves up along the main shaft 504, the second upper-layer gear 5032 meshes with the first upper-layer gear 5022 to form a high-speed transmission mode (transmission ratio 1:1.8); when moving down, the second lower-layer gear 5031 meshes with the first lower-layer gear 5021 to switch to a low-speed high-torque mode (transmission ratio 1:0.6). A single motor can achieve two-stage speed regulation and reduce energy consumption.

[0031] Combined with the attached Figure 4 : The control assembly 606 includes a transmission shaft 6063 that penetrates the side wall of the evaporation stirring cylinder 2 and is rotatably connected to the side wall of the evaporation stirring cylinder 2. A swing motor 6064 for the transmission shaft 6063 to rotate is provided on the outer wall of the evaporation stirring cylinder 2. A connecting block 6061 is provided on the plate body 607. One end of the connecting block 6061 away from the plate body 607 is slidably and rotatably connected with a seesaw 6062, and the end of the seesaw 6062 is fixedly connected with the transmission shaft 6063.

[0032] With this structure, when the swing motor 6064 drives the transmission shaft to rotate by ±30°, the swing motion is converted into the vertical displacement (stroke ±15 mm) of the plate body 607 through the rocker 6062, and the position of the second gear set is adjusted in real time.

[0033] When the present invention is specifically implemented, it operates according to the following steps: 1. Raw material mixing and dynamic speed regulation stage: Start the drive motor in the power base 1 to drive the three-axis bracket 501 to rotate at the basic speed. At this time: The second double-layer gear set 503 is in the initial middle position, the second lower-layer gear 5031 meshes with the first lower-layer gear 5021, forming a speed reduction transmission ratio of 1:0.6. The main stirring impeller 603 operates in a low-speed high-torque mode, pushing the high-viscosity raw materials from the bottom of the evaporation stirring cylinder 2 upwards; Under the differential action (the speed difference with the circular tray 601 reaches 35%), the spiral stirring wheel 604 lifts the bottom materials axially to the evaporation heater 602 area. The scraping frame 605 scrapes the cylinder wall with a gap of 2-3 mm to prevent the raw materials from carbonizing and coking.

[0034] 2. Evaporation intensity adjustment stage: When the viscosity of the material decreases to the set threshold value, the swing motor 6064 drives the transmission shaft 6063 to rotate by +25°, and pushes the plate body 607 upwards through the rocker 6062; The sleeve body 5033 moves upwards synchronously to make the second upper-layer gear 5032 mesh with the first upper-layer gear 5022, and switches to a speed increase transmission ratio of 1:1.8. The rotation speed of the main stirring impeller 603 is increased to 2.1 times the initial value, forming turbulent flow to enhance heat transfer. At this time, the power of the evaporation heater 602 is synchronously increased to 800 W / m² to achieve the dynamic matching of the evaporation rate and the stirring intensity.

[0035] 3. Gas-liquid separation and multi-stage condensation stage: The generated methanol vapor is pushed into the intake U-shaped pipe 303 by the induced draft fan 308 at a flow rate of 1.2 m / s: Primary condensation: 80% of the methanol vapor is condensed at the bottom of the intake U-shaped pipe 303 (the temperature is maintained at 45°C); Secondary condensation: The uncondensed gas enters the L-shaped condensation pipe 304 (with spiral guide vanes inside), and is further condensed under the action of 25°C cooling water. The liquid droplets are deposited by decelerating through the enlarged diameter section of the straight pipe 305; Tertiary recovery: The residual gas-phase substances are deeply condensed in the gradient temperature zone (from 60°C to 18°C) formed by the spiral heat conduction pipe 402 and the heat sink 403.

[0036] 4. Heat energy recovery and system maintenance stage: The waste heat (about 55 °C) collected in the condensate accumulation pipe 306 is conducted to the heat sink 403 through the heat conduction pipe 401, and forced convection by the fan 405 provides preheating for the intake U-shaped pipe 303 (raising the intake air temperature by 8 - 10 °C), reducing the energy consumption of steam reheating; During shutdown maintenance, the straight pipe 305 and the cylindrical frame 406 are disassembled, and the inner wall of the L-shaped condensate pipe 304 and the scraping frame 605 can be washed with high-pressure water, and the cleaning time is shorter than that of the traditional structure.

[0037] The above describes the present invention and its implementation manners, and this description is not restrictive. The actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative efforts without departing from the purpose of the present invention, they shall fall within the protection scope of the present invention.
