Description

Technical Field

[0001] This utility model relates to the field of gas distributor technology, specifically a bracket-free sintered metal powder gas distributor. Background Technology

[0002] In the fields of bio-fermentation, chemical engineering, pharmaceuticals, and food and beverage, gas distributors are one of the most common components used for gas distribution. Their function is to inject gas into a liquid through tiny orifices, providing numerous small bubbles. This creates a larger gas-liquid contact area in the liquid phase, enhancing mass transfer efficiency and leading to more complete reactions. The distribution of gas in the liquid phase directly affects mass transfer efficiency, and consequently, reaction efficiency.

[0003] Currently, existing metal plate and tubular gas distributors are manufactured by drilling holes in metal plates or tubes. On the one hand, the drilling process affects the strength of the metal material itself, requiring auxiliary supports for installation, making installation complex and difficult to disassemble. On the other hand, the size and number of holes are limited by factors such as drilling tools and metal thickness, resulting in large hole diameters, low open area ratios, high costs, long flow channels, and susceptibility to clogging and cleaning. Consequently, the distribution effect is not ideal, significantly increasing production time and reducing capacity.

[0004] Therefore, we propose a bracket-free sintered metal powder gas distributor to improve upon the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a bracket-free sintered metal powder gas distributor to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bracket-free sintered metal powder gas distributor, comprising a reactor, a mounting flange fixed to the bottom left side of the reactor, a core-filling flange mounted on the left side of the mounting flange, an interface metal pipe provided on the left side of the core-filling flange, an interface flange provided on the left side of the interface metal pipe, a connecting metal pipe mounted on the right side of the interface metal pipe, and a sintered metal powder microporous tube mounted on the right side of the connecting metal pipe.

[0007] Preferably, both the upper and lower ends of the mounting flange are fixed with connecting blocks, and the outer side walls of the connecting blocks are hinged with connecting rings. One side of the inner side of each connecting ring is movably provided with a locking block, and one end of each locking block is fixed to the outer side wall of the core-filling flange.

[0008] Preferably, the cross-section of the connecting ring is larger than the cross-section of the locking block, and the connecting ring and the locking block form an engaging structure.

[0009] Preferably, there are two sets of connecting rings and blocks, and the two sets of connecting rings and blocks are symmetrically distributed about the central axis of the mounting flange and the core flange, respectively.

[0010] Preferably, a mounting groove is provided on the left side inside the interface flange, a threaded mounting seat is movably disposed inside the mounting groove, and a filter screen is installed on the right side of the threaded mounting seat.

[0011] Preferably, the inner sidewall of the mounting groove is uniformly provided with internal threads, and the mounting groove and the threaded mounting seat form a threaded connection.

[0012] Preferably, the cross-section of the filter screen is smaller than the cross-section of the interface flange, and the filter screen and the interface flange form an engaging structure.

[0013] Preferably, the core-filling flange and the mounting flange are connected by bolts, and a sealing gasket is provided between the core-filling flange and the mounting flange.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the bracket-free sintered metal powder gas distributor not only facilitates installation and filters the gas entering the gas distributor, but also makes the installation connection between the core flange and the mounting flange more stable and secure.

[0015] This sintered metal powder microporous tube uses an asymmetric structure metal film. The critical connection points of the distributor do not use traditional welding techniques, but are instead integrally formed using vacuum sintering. Therefore, compared to common metal tube distributors, it is lighter and stronger, requires no support brackets, and is easier to install and disassemble, significantly saving manpower, resources, and installation materials.

[0016] By incorporating components such as threaded mounting bases, mounting slots, and filters, the gas distributor filters out impurities from the gas before it enters the gas distributor from the interface flange. This ensures that the gas is clean before it enters the gas distributor and then the reactor, resulting in better performance.

[0017] By incorporating components such as connecting blocks, connecting rings, and locking blocks, this gas distributor is installed on one side of the reactor by mounting the core flange together with the mounting flange. The addition of these components greatly increases the stability of the bolted installation between the core flange and the mounting flange, making it less prone to loosening and more stable to use.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides an embodiment: a bracket-free sintered metal powder gas distributor, including a reactor 7, an installation flange 4 fixed to the bottom left side of the reactor 7, a core-filling flange 3 installed on the left side of the installation flange 4, the core-filling flange 3 and the installation flange 4 are connected by bolts, a sealing gasket is provided between the core-filling flange 3 and the installation flange 4, an interface metal pipe 2 is provided on the left side of the core-filling flange 3, and an interface flange 1 is provided on the left side of the interface metal pipe 2, a connecting metal pipe 5 is installed on the right side of the interface metal pipe 2, and a sintered metal powder microporous pipe 6 is installed on the right side of the connecting metal pipe 5;

[0025] Specifically, such as Figure 1 and Figure 2 As shown, during installation, the gas distributor is directly inserted into the mounting flange 4 of the reactor 7 and installed together with the mounting flange 4 using bolts. When it is necessary to disassemble the gas distributor, simply unscrew the fastening bolts between the mating core flange 3 and the mounting flange 4 to remove the gas distributor.

[0026] Both ends of the mounting flange 4 are fixed with connecting blocks 8. Connecting rings 9 are hinged to the outer walls of the connecting blocks 8. A locking block 10 is movably arranged on one side inside the connecting ring 9, and one end of the locking block 10 is fixed to the outer wall of the core-filling flange 3. The cross-section of the connecting ring 9 is larger than the cross-section of the locking block 10. The connecting ring 9 and the locking block 10 form a locking structure. There are two sets of connecting rings 9 and locking blocks 10. The two sets of connecting rings 9 and locking blocks 10 are symmetrically distributed about the central axis of the mounting flange 4 and the core-filling flange 3, respectively. The design of the locking structure and the symmetrical distribution make the connection between the core-filling flange 3 and the mounting flange 4 more stable.

[0027] Specifically, such as Figure 1 and Figure 4 As shown, after the core-filling flange 3 and the mounting flange 4 are connected together by fastening bolts, the connecting ring 9 on the mounting flange 4 is flipped in sequence to engage with the locking block 10 above the core-filling flange 3, thereby reinforcing the core-filling flange 3 and the mounting flange 4 installed together and making them stably connected together.

[0028] An installation groove 12 is provided on the left side inside the interface flange 1. A threaded mounting seat 11 is movably installed inside the installation groove 12, and a filter screen 13 is installed on the right side of the threaded mounting seat 11. The inner sidewall of the installation groove 12 is uniformly provided with internal threads. The installation groove 12 and the threaded mounting seat 11 form a threaded connection, which facilitates the disassembly and maintenance of the filter screen 13. The cross-section of the filter screen 13 is smaller than the cross-section of the interface flange 1. The filter screen 13 and the interface flange 1 form a snap-fit ​​structure, which improves the filtration of gas.

[0029] Specifically, such as Figure 1 and Figure 3 As shown, before the external gas enters the reactor 7, the filter screen 13 filters out impurities and dust in the gas, making the gas clean before it enters the reactor 7. Subsequently, the threaded mounting base 11 can be rotated to detach it from the mounting groove 12, thereby removing the filter screen 13 for maintenance.

[0030] Working Principle: This utility model uses an interface flange 1, an interface metal pipe 2, a core flange 3, a connecting metal pipe 5, and a sintered metal powder microporous tube 6 to form a gas distributor. (The sintered metal powder microporous tube 6 is sintered using the novel asymmetric structure metal film technology described in application number: CN202221003410.8). The connecting metal pipe 5 and the sintered metal powder microporous tube 6 are sintered together in a vacuum sintering furnace. During installation, the gas distributor is directly inserted into the mounting flange 4 of the reactor 7 and installed together with bolts. Then, the connecting retaining ring 9 on the mounting flange 4 is flipped to engage with the retaining block 10 above the core flange 3, thus securing the connection between the mounting flange 4 and the core flange 3. After reinforcement during installation, external gas is filtered by filter screen 13 to remove internal impurities and dust before entering the gas distributor through interface flange 1. The gas flows from the inside out through the gas distributor. Due to the unique microporous metal structure of the gas distributor, which provides thousands of flow paths, the gas is discharged as a large number of very small bubbles. These millions of tiny bubbles, with diameters between 1μm and 10mm, generated by the gas distributor are introduced into the reaction vessel 7, increasing the contact area between the gas and liquid, thereby enhancing the mass transfer rate and increasing production capacity. When disassembling the gas distributor, simply unscrew the fastening bolts of the mating core flange 3 and the mounting flange 4 to remove the gas distributor.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
