Description

Technical Field

[0001] This utility model relates to the field of petrochemical equipment technology, specifically to a gasification reactor with a detachable distributor. Background Technology

[0002] Fluidized bed reactors are typically vertically installed devices with a gas distributor at the bottom, riddled with distribution holes. This distributor optimizes gas flow, allowing the rising gas to form a well-fluidized gas-solid contact with the incoming material, supporting long-term reaction cycles and preventing material from entering the gas chamber below the distributor under any operating condition. Gas distributors are widely used in energy and chemical industries such as olefin polymerization, hydrogenation, and coal gasification. Gas distributor technology is also applied to process equipment in drying and separation processes. Therefore, the reaction distributor is a key structural component of gas-phase reactors.

[0003] Chinese patent document CN111298728B discloses a gas distributor and its application in an HCl oxidation fluidized bed. The gas distributor includes a gas distribution plate, which is divided into a circular central area and an annular sidewall area. Air inlets are evenly distributed on the gas distribution plate, and each air inlet is sealed with a porous vent cap above it by a metal cover plate. The porous vent cap is a SiC porous sintered vent cap. The angle between the inclined surface of the porous vent cap in the central area and the horizontal direction is smaller than that in the sidewall area, and the wall thickness of the porous vent cap in the central area is greater than that in the sidewall area. This method can solve the technical problems of uneven gas distribution in fluidized beds, poor fluidization quality, erosion and corrosion of reactor internals, and catalyst wear and pulverization.

[0004] For example, Chinese patent document CN215540726U discloses a gas distributor and a fluidized bed reactor using the gas distributor, including a distribution plate with multiple air vents on the distribution plate, and a cap disposed below the distribution plate with its opening facing upward. The cap corresponds to the air vents, and multiple air guide holes are provided on the side wall of the cap. A baffle is provided inside the cap, located around the air guide holes. A channel for gas to pass through is left between the baffle and the air guide holes, and the gas discharged from the air guide holes is guided downward.

[0005] However, for the connection between the wind cap and the distribution plate, the existing technology generally uses half-pipe sections as gas caps, which are directly welded and fixed to the top of the distribution plate. The densely arranged half-pipe section gas caps are continuously welded to the top surface of the distribution plate on both sides to achieve a seal, so that the hydrocarbon gas is only ejected from both ends of the gas cap.

[0006] Traditional distribution plates are solid, thick plates, which are inconvenient to transport over long distances, unsafe to hoist and move, time-consuming and labor-intensive to process, and require a mountain of metal pins for drilling. They also cannot be adjusted after long-term use due to deformation. Furthermore, they are costly and inconvenient to replace. Utility Model Content

[0019] As a further optional solution, filler is provided between the panel and the base plate.

[0021] As a further alternative, both ends of the jet passage are connected to the mixing chamber, or only one end of the jet passage is connected to the mixing chamber.

[0022] As a further optional solution, the inner wall of the cylinder is provided with a clamping structure for fixing the distribution plate.

[0024] This utility model discloses a gasification reactor with a detachable distributor, which has the following advantages compared with the prior art:

[0025] (1) Facilitates the design of special arc-shaped structures for the distributor. Compared to a traditional solid steel plate, the panel and bottom plate can be made thinner, making them easier to bend and shape, and adapting to the field optimization required for fluidized bed reactions inside the cylinder. When it is necessary to adjust the tilt angle or curvature of the top and bottom surfaces of the distributor, it can be adjusted by replacing the positioning sleeves and inner tubes of different lengths, which is highly flexible.

[0032] Further optimization,

[0033] (8) The filler between the panel and the base plate can also be a special-shaped small module designed and manufactured specifically for the shape of the gap between the air tube components. The small module can be pre-cast from plastic or other non-metallic plastic.

[0034] (9) Non-metallic air tube components can be injection molded into an integrated main component using engineering plastics, and the positioning sleeve can also be made of engineering plastic tubes to reduce weight and cost.

[0035] (10) Facilitates the design of special material structures for the distributor.

[0049] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0050] This embodiment describes a gasification reactor with a detachable distributor, such as... Figure 1 and Figure 2 As shown, the device includes a vertical cylinder 1, inside which is a horizontally placed distribution plate 2. The distribution plate 2 divides the cylinder 1 into a mixing chamber 11 and an air inlet chamber 12 arranged vertically. The mixing chamber 11 is connected to a feed pipe 13 and a discharge pipe 14, and the air inlet chamber 12 is connected to an air inlet pipe 15. During use, the gas rises and passes through the distributor, forming a well-fluidized gas-solid contact with the material entering from above.

[0051] In this embodiment, the distribution plate 2 includes a front panel 23 and a bottom plate 24 arranged vertically. The front panel 23 and bottom plate 24 each have a plurality of aligned distribution holes 21. During processing, the front panel 23 and bottom plate 24 are fitted together and the aligned holes are drilled. Each pair of distribution holes 21 is equipped with an air pipe assembly. Each air pipe assembly includes an inner tube 3, a positioning sleeve 4, an air cap 5, and a locking element 9. The positioning sleeve 4 is located between the front panel 23 and the bottom plate 24 and aligned with the distribution holes 21. The upper end of the positioning sleeve 4 abuts against the bottom of the front panel 23, and the lower end of the positioning sleeve 4 is supported on the top surface of the bottom plate 24, thereby maintaining the distance between the front panel 23 and the bottom plate 24 and bearing the pressure when the nut is tightened. In practice, annular limiting grooves for the positioning sleeve 4 to be inserted can be provided on the bottom surface of the front panel 23 and the top surface of the bottom plate 24 to facilitate the positioning of the positioning sleeve 4.

[0052] The inner tube 3 passes through the positioning sleeve 4, and the air cap 5 is connected to the upper end of the inner tube 3. The lower end of the inner tube 3 passes through the base plate 24 and is connected to the locking member 9, so that the air cap 5 presses against the panel 23 downwards while the locking member 9 supports the base plate 24 upwards. In this way, the air cap 5 and the locking member 9 together clamp the distribution plate 2. Such an inner tube 3 is equivalent to a special hollow bolt, and the air cap 5 is the head of the bolt.

[0053] Each air cap 5 is elongated and has an arc-shaped cross-section. The arc-shaped opening is attached to the top surface of the panel 23, so that the air cap 5 and the panel 23 together form the jet channel 51. The air inlet chamber, the inner cavity pipe 3, the jet channel 51 and the mixing chamber are connected in sequence. Both ends of the jet channel 51 are connected to the mixing chamber, or only one end of the jet channel 51 is connected to the mixing chamber.

[0054] In this embodiment, the two long sides of the air cap 5 are welded and fixed to the upper end of the inner tube 3.

[0055] In this embodiment, the locking component 9 is a fastening nut, and the lower end of the inner tube 3 is provided with an external thread that matches the fastening nut; the fastening nut is a single nut or a double nut, or a functional structure with a self-locking washer to prevent loosening due to airflow vibration.

[0056] In this embodiment, the panel 23 and the base plate 24 are circular flat plates. In practice, the materials or thicknesses of the panel 23 and the base plate 24 may be the same or different. The panel 23 and / or the base plate 24 are arc-shaped plates, and the lengths of the positioning sleeves 4 of the multiple distributed holes 21 are different. The arc-shaped plates are elastically deformed to fit the positioning sleeves 4 by means of the locking element 9. When the panel 23 or the base plate 24 needs to form an arc surface, the plate that needs to form an arc surface is designed to be less rigid, and the plate that does not need to form an arc surface is designed to be sufficiently rigid. The lengths of the corresponding positioning sleeves 4 and inner tubes 3 change, and the less rigid plate surface can be gradually deformed by forcefully tightening the nut, so that the whole can form an arc surface. The deformed panel 23 has the elasticity to restore its flat surface, and this elasticity can play a self-tightening role with the nut.

[0057] In this embodiment, the spacing between adjacent airway components is uniform or non-uniform. Depending on the flow distribution in the design simulation, the spacing can be locally increased if necessary.

[0058] The inner tube 3 is cylindrical or conical. The conical shape, which is larger at the bottom and smaller at the top, allows airflow to enter the large opening of the inner tube 3 smoothly, reducing resistance and maintaining air pressure. The small-diameter outlet of the inner tube 3 can pressurize the airflow to form the desired flow pattern.

[0059] In this embodiment, a filler 8 is provided between the panel 23 and the base plate 24. The filler 8 can be a heat-insulating filler 8, a foamed filler 8, or other castable material. The foamed castable material can be added after the distribution plate 2 is assembled, so that the foam fills the remaining space between the panel 23 and the base plate 24, and also plays a sealing role, blocking the internal short-circuit gaps. Overall, it is a lightweight non-metallic material, which not only saves metal, but also reduces the stress on the base plate 24.

[0060] In this embodiment, the inner wall of the cylinder 1 is provided with a clamping structure for fixing the distribution plate 2. The clamping structure includes a support ring 6 and a clamping ring 7 welded and fixed to the inner wall of the cylinder 1. The support ring 6 faces upward to support the bottom periphery of the bottom plate 24, and the clamping ring 7 faces downward to press down on the top periphery of the panel 23. A positioning groove 22 is provided on the top periphery of the distribution plate 2, and the clamping ring 7 is embedded in the positioning groove 22. This clamping structure serves two purposes: first, to ensure that the assembly can proceed smoothly within the design tolerances during manufacturing and assembly, avoiding excessive unevenness of the circular flat plate distribution plate 2 when only the lower support ring 6 is present; second, to clamp the distribution plate 2 to prevent it from shaking due to upward airflow pressure difference or structural vibration during operation, which would affect the fluidized bed state. This vertical clamping connection between the distribution plate 2 and the cylinder 1, due to its circumferential continuity, is treated as a simply supported boundary during design verification, which is more conservative than the calculation results of a simply supported boundary and is more suitable for engineering purposes.

[0061] In this embodiment, as Figure 3 As shown, multiple distribution holes 21 are evenly distributed in an equilateral triangle on the distribution plate 2, and each air cap 5 is arranged along the side of the triangle. The multiple air caps 5 are arranged in multiple rows, and the tilting directions of adjacent rows of air caps 5 are different.

[0062] like Figure 4 As shown, in the first configuration of the air cap 5, the air cap 5 is a semi-circular arc plate bisected by a cross-section passing through the centerline of a circular tube, and the cross-sectional area of ​​the jet passage 51 is equal everywhere. It can be referred to as a semi-circular tube passing through the centerline.

[0063] like Figure 5 As shown, this is the second type of air cap 5, where the cross-section intersects the centerline of the circular tube at an angle, thus the cross-sectional area of ​​the jet channel 51 gradually changes along its length. During welding, the cross-section is flush with the top surface of the panel 23. This jet channel 51 has a certain slope, resulting in smoother airflow, reduced pressure drop, and greater energy efficiency. The same applies below.

[0064] like Figure 6 As shown, as a third type of air cap 5, the cross-sectional area of ​​the jet channel 51 gradually changes from the middle to both ends. This is equivalent to two... Figure 5 The structures shown are used in combination.

[0065] like Figure 7 As shown, as the fourth type of air cap 5, the cross section not only intersects the center line of the circular tube at an angle, but is also diagonally tangent to both ends of the circular tube, so that two air caps 5 can be cut out from a section of the circular tube.

[0066] Compared with the prior art, the gasification reactor of this embodiment has the following advantages:

[0067] First, it facilitates the design of special curved surface structures for the distributor. Compared to a traditional solid steel plate, the panel 23 and the base plate 24 can be made thinner, are easier to bend and shape, and adapt to the field optimization required for fluidized bed reaction inside the cylinder 1.

[0068] Secondly, it facilitates the design of special modular structures for the distributor. Modules that can enter and exit through the manhole in the cylinder can be assembled into modules of a preset area through regular arrangement.

[0069] Third, it facilitates the design of special material structures for the distributor. It allows for greater freedom in selecting and optimizing the materials for the panel 23 and the base plate 24, especially by choosing a non-metallic material for the panel 23 that will not oxidize or rust, thus avoiding contamination of the reaction medium and products. It also prevents the impact and pulverization of reaction products when they settle onto the panel 23, reducing noise caused by impacts.

[0070] Fourth, non-metallic air tube components can be injection molded into an integrated main part using engineering plastics, and the positioning sleeve 4 can also be made of engineering plastic tubing to reduce weight and cost.

[0071] Fifth, thick steel plates are avoided for the panel 23 and the base plate 24. This reduces material costs and is environmentally friendly and energy-efficient.

[0072] Sixth, the use of thin steel plates for the panel 23 and the base plate 24 facilitates procurement; they can also be assembled and welded from small plates into large plates, which facilitates leveling; and also facilitates safe hoisting and transportation.

[0073] Seventh, the panel 23 and the base plate 24 are made of thin steel plates, which are easy to drill, saving time, effort and drill bit consumables.

[0074] Eighth, it is easy to assemble. The inner tube 3 / positioning sleeve 4 is assembled from common small parts, making it lightweight and easy to move.

[0075] Ninth, it facilitates maintenance, replacement, or technical upgrades.

[0076] Tenth, the filler 8 between the panel 23 and the base plate 24 can also be a special-shaped small module designed and manufactured specifically for the shape of the gap between the air tube components. The small module can be pre-cast from plastic or other non-metallic plastics.

[0077] It should be noted that this case is an improvement based on the premise that a vent is set on the top of the distribution plate 2. Therefore, when evaluating the inventiveness of this case, it should start from this premise. Under the premise that a vent is set on the top of the distribution plate 2, there is no prior art that discloses a technology to separate the distribution plate 2. Evaluating the distribution plate 2 without this premise would deviate from the technical concept of this case. Furthermore, the "distribution plate 2 + vent" should be evaluated as a whole. It is meaningless to ignore one of them.

[0078] Furthermore, in conventional thinking, the distribution plate 2 is used to allow gas to pass through and support the gas cap. It only requires opening holes in the solid steel plate. There is no motivation to disassemble the complete steel plate. Therefore, this case is not a conventional technical means and has outstanding substantive features and significant progress.
