Description

Technical Field

[0001] This invention relates to the field of furoic acid processing technology, and more specifically to a high-efficiency gas-slag separation device suitable for furoic acid processing. Background Technology

[0002] Furoic acid is a white, monoclinic, elongated spindle-shaped crystal, slightly soluble in cold water, readily soluble in hot water, ethanol, and ether, and easily sublimes upon heating. Furoic acid is generally obtained through the oxidation reaction of furfural. Furfural is a colorless, transparent, oily liquid with a characteristic odor similar to benzaldehyde. Upon exposure to light and air, its color quickly turns reddish-brown. The furfural processing includes raw material preparation, hydrolysis reaction, distillation purification, refining, and treatment of waste residue and wastewater.

[0003] In the furfural processing, the core function of the gas-slag separation unit is to effectively separate the furfural vapor produced by the reaction from solid residues (such as residues from raw materials like corn cobs). The gas-slag separation unit used in furfural processing separates solid particles carried by high-temperature steam into the separator. Through cyclone separation or gravity settling, the solid particles are deposited at the bottom of the separator due to inertia or gravity, while the furfural vapor enters the subsequent condensation or distillation system through the top outlet. However, traditional separators are poor at separating small particles, causing solid residues to enter the subsequent system with the steam, potentially clogging pipes or affecting condensation efficiency.

[0004] Therefore, there is a need to provide a high-efficiency gas-slag separation device suitable for furoic acid processing, which aims to solve the above problems. Summary of the Invention

[0020] In summary, the embodiments of the present invention have the following beneficial effects compared with the prior art:

[0021] 1. In this invention, furfural vapor mixed with solid residue enters the separator through the inlet pipe. The rotating component drives the first filter component to rotate synchronously by rotating the support turntable, which can perform primary filtration of the solid residue mixed in the furfural vapor. The second filter component improves the filtration effect of the furfural vapor by filtering it again. The furfural vapor after secondary filtration is discharged to the subsequent processing device through the second filter component, realizing multiple filtration of furfural vapor. It can efficiently filter small particles and improve the efficient separation of gas and residue in furfural vapor. The reciprocating adjustment component drives the second filter component to reciprocate and lift. At the same time, it can realize the synchronous lifting and lowering of the first filter component, which facilitates the comprehensive filtration of the first and second filter components and avoids the problem of solid residue accumulating in one place and clogging the filter channel. It can effectively maintain the efficiency of secondary filtration.

[0022] 2. In this invention, the filter screen filters the solid residue mixed in the furfural vapor introduced from the air inlet pipe by revolving around the central axis, achieving primary filtration of the furfural vapor. At the same time, the rotating gear drives the movable rotating rod and the filter screen to rotate by meshing with the fixed internal gear ring. The filter screen can achieve double-sided filtration by rotating, and can prevent solid residue from accumulating on one side of the filter screen. The furfural vapor blows the solid residue accumulated on one side of the filter screen out by blowing it to both sides of the filter screen, avoiding solid residue from accumulating on one side of the filter screen and causing blockage of the filtration channel. In addition, by setting up several filter screens, it can effectively prevent furfural vapor and solid residue from directly contacting the inner wall of the separator, reducing the wear of the inner wall of the separator and improving the service life of the separator.

[0023] 3. In this invention, the air guide pipe drives the scraper to rotate by connecting to the first crossbar. The scraper scrapes off the solid residue adhering to the inner wall of the installation mesh cylinder by contacting the inner wall of the installation mesh cylinder, thereby preventing the solid residue from accumulating in the filter channel of the installation mesh cylinder and helping to maintain the efficiency of secondary filtration.

[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0041] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0042] In one embodiment of the present invention, see Figures 1-3A high-efficiency gas-slag separation device suitable for furfural processing includes a separation tank 1, which is configured as a funnel. An inlet pipe 101 is provided at the top of the separation tank 1 for introducing furfural vapor mixed with solid residue. A collection cylinder 102 is provided at the bottom of the separation tank 1. A connecting ring cover 2 is provided at the top of the separation tank 1. A second filter assembly 6 is movably mounted on the connecting ring cover 2. A support turntable 3 is rotatably mounted on the connecting ring cover 2. A gas guide pipe 301 connecting the separation tank 1 and the second filter assembly 6 is provided on the support turntable 3. Several gas guide ports 302 are circumferentially distributed at one end of the gas guide pipe 301 near the second filter assembly 6. A rotating assembly 5 connected to the support turntable 3 is provided on the connecting ring cover 2. A first filter assembly 4 is provided inside the separation tank 1, passing through the support turntable 3 and movably connected to the second filter assembly 6. A reciprocating adjustment assembly 7 connected to the gas guide pipe 301 is provided between the connecting ring cover 2 and the second filter assembly 6.

[0043] In this embodiment, furfural vapor mixed with solid residue enters the separator 1 through the inlet pipe 101. The rotating component 5 drives the first filter component 4 to rotate synchronously by rotating the support turntable 3, which can perform a primary filtration of the solid residue mixed in the furfural vapor. The solid residue after primary filtration falls into the collection cylinder 102, achieving the collection of fixed residue. At the same time, the furfural vapor after primary filtration enters the second filter component 6 through the air guide pipe 301 and air guide port 302. The second filter component 6 improves the filtration effect of furfural vapor by filtering it again. The furfural vapor after secondary filtration... The steam is discharged to the subsequent treatment device through the second filter assembly 6, which can achieve multiple filtration of furfural steam, and can efficiently filter out small particles, improving the efficient separation of gas and slag in furfural steam. Through the reciprocating adjustment assembly 7, the second filter assembly 6 can be driven to reciprocate and rise and fall. At the same time, the first filter assembly 4 can be raised and lowered synchronously, which facilitates the comprehensive filtration of the first filter assembly 4 and the second filter assembly 6, avoiding the problem of solid residue accumulating in one place and clogging the filter channel. It can effectively maintain the efficiency of secondary filtration, and has the effects of multiple filtration, efficient separation, double anti-clogging, flexible linkage, reliable structure and simple and practical use.

[0044] The outer wall of the separation tank 1 is provided with an outer support 103. The outer support 103 can stably support the separation tank 1 and improve the stability of the device. The bottom of the separation tank 1 and the collection cylinder 102 can be connected by a threaded connection. When enough solid residue is collected in the collection cylinder 102, the collection cylinder 102 can be rotated counterclockwise to disconnect the connection between the collection cylinder 102 and the separation tank 1 and clean the solid residue collected in the collection cylinder 102. After cleaning, the collection cylinder 102 is aligned with the bottom of the separation tank 1, and the collection cylinder 102 is rotated clockwise to connect the collection cylinder 102 and the bottom of the separation tank 1, which facilitates the centralized collection of solid residue.

[0045] In one embodiment of the present invention, see Figures 1-4 The rotating component 5 includes a driven bevel gear 503 disposed on the supporting turntable 3, and a driving bevel gear 502 that meshes with the driven bevel gear 503 is movably disposed on the connecting ring cover 2. The driving bevel gear 502 is connected to a rotary motor 501 mounted on the connecting ring cover 2.

[0046] In this embodiment, the rotary motor 501 drives the active bevel gear 502 to rotate. The active bevel gear 502 drives the support turntable 3 to rotate synchronously by meshing with the driven bevel gear 503 and by rotating with the connecting ring cover 2. The support turntable 3 drives the first filter assembly 4 to rotate synchronously, which can filter solid residues. At the same time, the support turntable 3 drives the air guide pipe 301 to rotate synchronously. The air guide pipe 301 drives the first filter assembly 4 and the second filter assembly 6 to move up and down synchronously by connecting with the reciprocating adjustment assembly 7 and by moving with the first filter assembly 4 and the second filter assembly 6, which helps to filter comprehensively and improve the gas-sludge separation efficiency.

[0047] In one embodiment of the present invention, see Figures 1-6 The first filter assembly 4 includes a fixed internal gear ring 401 fixedly disposed on the inner wall of the connecting ring cover 2. The bottom of the support turntable 3 has a plurality of rotating gears 402 circumferentially distributed. The rotating gears 402 are rotatably connected to the support turntable 3. A movable rotating rod 403 is slidably disposed inside the rotating gear 402. One end of the movable rotating rod 403 is connected to a filter screen 404 movably disposed inside the separation tank 1. The other end of the movable rotating rod 403 passes through the support turntable 3 and is connected to a limiting wheel 405 movably disposed outside the separation tank 1. The bottom of the second filter assembly 6 is provided with a retaining ring 406 that is movably engaged with the plurality of limiting wheels 405.

[0048] In this embodiment, the rotary motor 501 drives the support turntable 3 to rotate by driving the active bevel gear 502 to rotate and by the active bevel gear 502 meshing with the driven bevel gear 503. The support turntable 3 drives the rotating gears 402 to revolve around the central axis of the support turntable 3 by being rotatably connected to several rotating gears 402. The rotating gears 402 drive the movable rotating rod 403 and the filter screen 404 to revolve synchronously by slidingly engaging with the movable rotating rod 403. The filter screen 404 filters the solids mixed in the furfural vapor introduced from the air inlet pipe 101 by revolving around the filter screen. The solid residue is filtered to achieve primary filtration of furfural vapor. At the same time, the rotating gear 402 drives the movable rotating rod 403 and the filter screen 404 to rotate by meshing with the fixed internal gear ring 401. The filter screen 404 can achieve double-sided filtration by rotating, and can prevent solid residue from accumulating on one side of the filter screen 404. The furfural vapor blows the solid residue accumulated on one side of the filter screen 404 out by blowing it to both sides of the filter screen 404, thus avoiding solid residue from accumulating on one side of the filter screen 404 and causing blockage of the filter channel.

[0049] In addition, the long-term scouring of high-temperature steam and solid residue may cause wear on the inner wall of the separator 1, especially the metal separator; the acidic substances in furfural vapor may corrode the equipment and shorten its service life; by setting up the filter screen 404, the furfural vapor and solid residue can be effectively prevented from directly contacting the inner wall of the separator 1, reducing the wear on the inner wall of the separator 1 and improving the service life of the separator 1.

[0050] The movable rotating rod 403 is provided with a first guide groove 4031, and the rotating gear 402 is slidably engaged with the first guide groove 4031. The rotating gear 402 drives the movable rotating rod 403 to rotate synchronously by slidingly engaging with the first guide groove 4031, which can realize the synchronous rotation of the filter screen 404.

[0051] In one embodiment of the present invention, see Figures 1-8 The second filter assembly 6 includes a movable cylinder 601 movably disposed above the connecting ring cover 2. The movable cylinder 601 is movably sleeved on the outside of the air guide tube 301. The retaining ring 406 is disposed at the bottom of the movable cylinder 601. An exhaust hole 6011 is provided on the upper part of the outer wall of the movable cylinder 601. An installation cover 602 is installed on the movable cylinder 601. An inverted installation mesh cylinder 603 is provided inside the movable cylinder 601. A plurality of elastic rods 606 are provided between the installation cover 602 and the installation mesh cylinder 603. A plurality of scrapers 604 are distributed circumferentially inside the installation mesh cylinder 603 and contact the inner wall of the installation mesh cylinder 603. The side of the scraper 604 away from the installation mesh cylinder 603 is connected to the air guide tube 301 through a first crossbar 605.

[0052] In this embodiment, the furfural vapor, after being filtered once by the filter screen 404, enters the interior of the mounting screen cylinder 603 through the air guide pipe 301 and the air guide port 302. The furfural vapor then passes through the mounting screen cylinder 603 and is discharged to the subsequent processing device through the exhaust port 6011, which can realize the secondary filtration of furfural vapor and improve the efficient separation of gas and slag. At the same time, the rotary motor 501 drives the active bevel gear 502 to rotate. The active bevel gear 502 drives the support turntable 3 to rotate synchronously by meshing with the driven bevel gear 503 and by rotating the support turntable 3 with the connecting ring cover 2. The support turntable 3 drives the air guide pipe 301 to rotate synchronously. The air guide pipe 301 drives the scraper 604 to rotate by connecting with the first crossbar 605. The scraper 604 scrapes off the solid residues adhering to the inner wall of the mounting screen cylinder 603 by contacting the inner wall of the mounting screen cylinder 603, avoiding the accumulation of solid residues in the filter channel of the mounting screen cylinder 603, which helps to maintain the efficiency of secondary filtration.

[0053] The elastic rod 606 can fix the position of the installation net cylinder 603, preventing the installation net cylinder 603 from rotating synchronously with the scraper 604.

[0054] In one embodiment of the present invention, see Figures 1-8 The reciprocating adjustment assembly 7 includes a fixed rotating rod 701 connected to the top of the air guide tube 301. One end of the fixed rotating rod 701 passes through and is installed with a mesh cylinder 603 and a connecting ring cover 2. A second guide groove 7011 is provided on the side wall of the end of the fixed rotating rod 701 that passes through the connecting ring cover 2. A threaded hole 7012 is provided at the center of the end of the fixed rotating rod 701 near the second guide groove 7011. A slide cylinder 702 is provided on the outer side of the fixed rotating rod 701 that slides in cooperation with the second guide groove 7011. A movable adjustment ring 704 is movably provided on the outer side of the fixed rotating rod 701. The movable adjustment ring 704 and the slide cylinder 702 are connected by a plurality of circumferentially distributed second crossbars 70 The three components are connected. The movable adjusting ring 704 has an arc surface at one end near the connecting ring cover 2. The top of the connecting ring cover 2 has a fixed arc plate 706 that slides with the arc surface of the movable adjusting ring 704. The fixed rotating rod 701 has a connecting screw 705 that is threaded to the threaded hole 7012 at one end near the second guide groove 7011. The connecting screw 705 is used to limit the position of the slide cylinder 702. Several side sliders 709 are distributed circumferentially on the outer wall of the movable cylinder 601. A vertical rod 707 connected to the connecting ring cover 2 slides inside the side sliders 709. A spring 708 sleeved on the outside of the vertical rod 707 is connected between the connecting ring cover 2 and the side sliders 709.

[0055] In this embodiment, in the initial state, the highest point of the arc surface of the movable adjusting ring 704 is in contact with the highest point of the fixed arc plate 706, the spring 708 is at its original length, and the movable cylinder 601 is at its highest point.

[0056] The rotary motor 501 drives the driving bevel gear 502 to rotate. The driving bevel gear 502 drives the supporting turntable 3 to rotate synchronously through meshing with the driven bevel gear 503 and through the rotational engagement between the supporting turntable 3 and the connecting ring cover 2. The supporting turntable 3 drives the air guide pipe 301 to rotate synchronously, and the air guide pipe 301 drives the fixed rotating rod 701 to rotate synchronously. The fixed rotating rod 701 drives the movable adjusting ring 704 through the sliding engagement between the second guide groove 7011 and the slide cylinder 702, the connection between the connecting screw 705 and the threaded hole 7012, and the connection between the second crossbar 703 and the movable adjusting ring 704. 704 rotates synchronously. The movable adjusting ring 704 drives the movable cylinder 601 and the mounting cover 602 to reciprocate up and down through the contact between its arc surface and the fixed arc plate 706, the sliding cooperation between the side slider 709 and the upright rod 707, and the elastic action of the spring 708. The mounting cover 602 drives the mounting screen cylinder 603 to rotate synchronously through the elastic connection with the elastic rod 606. This facilitates the scraper 604 to thoroughly scrape the inner wall of the mounting screen cylinder 603. At the same time, it prevents furfural vapor from passing through the fixed ring area on the side wall of the mounting screen cylinder 603 for a long time, which can improve the filtration utilization rate of the side wall of the mounting screen cylinder 603.

[0057] Furthermore, the movable cylinder 601 drives the retaining ring 406 to move up and down synchronously. The retaining ring 406 drives the movable rotating rod 403 to move up and down reciprocally by engaging with the limiting wheel 405 and sliding with the first guide groove 4031 and the rotating gear 402. The movable rotating rod 403 drives the filter screen 404 to move up and down synchronously, which can improve the utilization rate of the filter screen 404, prevent furfural vapor from passing through the fixed area of ​​the filter screen 404 for a long time, help maintain the gas-slag separation efficiency of furfural vapor, and improve the practicality and service life of the device.

[0058] Once a certain amount of solid residue has been scraped from the installation mesh cylinder 603, disconnect the connection between the separation tank 1 and the connecting ring cover 2, remove the connecting ring cover 2 and its components, then disconnect the threaded connection between the connecting screw 705 and the threaded hole 7012, pull out the sliding cylinder 702, and release the installation of the movable adjusting ring 704. Then, flip the movable cylinder 601 and the installation cover 602 so that the movable cylinder 601 is above the installation cover 602. Next, disconnect the connection between the movable cylinder 601 and the installation cover 602, open the end of the movable cylinder 601 near the installation cover 602, release the fixing of the installation mesh cylinder 603, and pull out the installation mesh cylinder 603 to collect and clean the accumulated solid residue.

[0059] The vertical distance between the lowest point and the highest point of the arc surface of the movable adjusting ring 704 is less than the length of the upright 707, which can avoid interference in the lifting and lowering movement of the fixed internal gear ring 401 and improve the stability of the device operation.
