Description

Technical field

[0001] The utility model relates to the field of fluidized bed devices, in particular to a quick-install fluidized bed device. [Background Technology]

[0002] A fluidized bed, abbreviated as fluidized bed, is a reactor that uses gas or liquid to pass through a granular solid layer to put the solid particles into a suspended motion state and carry out a gas-solid phase reaction process or a liquid-solid phase reaction process.

[0003] For example, the diameter of a fluidized bed with a capacity of less than 30,000 tons is about 3 meters, and with the auxiliary parts transportation diameter reaching 5 meters, it can still be transported by road. Therefore, we can manufacture the entire fluidized bed device in the factory during manufacturing and then transport it to the customer's site. However, with the development of technology, fluidized bed devices are getting larger and larger. The diameter of some fluidized bed devices has reached 5 to 7 meters, and with the auxiliary parts transportation diameter reaching 10 to 12 meters. Therefore, due to its large diameter, the entire fluidized bed device cannot be assembled as a whole in the manufacturing plant and then transported to the customer's site by road. In order to solve this technical problem, the industry generally does this in the existing technology: first, the various internal components of the fluidized bed are manufactured in the manufacturing plant, and then workers are sent to the customer's site to assemble them, which leads to a huge workload for on-site assembly at the customer's site. Taking a fluidized bed device with a diameter of 5 meters and a diameter of 10 meters for auxiliary parts transportation as an example, it takes about 30 workers to install it on-site at the customer's site for 180 days. If there is a lot of rain, the installation will be postponed. Therefore, the equipment manufacturing cost is significantly increased and work efficiency is reduced. Therefore, we thought about how to make the heat exchange tubes and corrugated baffles into a modular structure in the manufacturing plant, and then transport the modular structure to the site for workers to assemble several modular structures. This not only solves the transportation problem, but also greatly improves the assembly efficiency of workers at the customer unit site. The present utility model aims to provide such a quick-install fluidized bed device. [Utility Model Content]

[0007] Preferably, a quick-install fluidized bed device in the present invention is further configured as follows: an intermediate reinforcing rib is provided in the guide vertical pipe at a position corresponding to the vertical groove.

[0008] Preferably, a quick-install fluidized bed device in the present invention is further configured as follows: a gap is provided between every two adjacent heat exchange tubes and the corrugated baffle modules, and an inclined thin plate welded to the edge strips of the corrugated baffle is provided in the gap.

[0012] Preferably, the quick-install fluidized bed device in the present invention is further configured as follows: the corrugated baffle is arranged in a quarter circle.

[0013] Compared with the existing technology, the present invention has the following beneficial effects: the present invention designs the heat exchange tubes and corrugated baffles, which are relatively complicated in process and installation, into a module structure, which not only greatly reduces the difficulty of transportation, but also compared with the existing technology of transporting each internal component to the site for installation, the present invention only needs to install several modules on site, which not only greatly improves the installation efficiency, but also by adding guide vertical pipes in the equipment and setting guide plates on the inner side strips of the corrugated baffle, the installation accuracy of the assembly workers when assembling the modules on site is also guaranteed. In addition, considering that there is a gap between the modules after the modules are assembled, which will cause airflow short-circuiting, we have set an inclined thin plate in the gap.

[0024] The following is a further detailed description of the quick-install fluidized bed device of the present invention through specific embodiments.

[0025] Ginseng Figures 1 to 9 As shown, a quick-install fluidized bed device includes: a shell 1, a gas pre-distributor 10 and a feed port 11 are provided at the bottom of the shell 1, a discharge port 12 is provided at the top of the shell 1, a gas distribution plate 13 is provided in the shell 1, and a guide vertical pipe 2 and several groups of heat exchange tubes and corrugated baffle modules 3 arranged along the circumferential direction are provided above the gas distribution plate 13 in the shell 1. In this embodiment, the number 3 of heat exchange tubes and corrugated baffle modules is four groups. Of course, in other embodiments, the number of heat exchange tubes and corrugated baffle modules 3 can also be three groups, five groups or even more groups, which can be determined according to specific production needs.

[0026] The guide tube 2 is connected to the inner wall of the shell 1 via a connector 4. Four vertical slots 20 are provided at the bottom of the guide tube 2, evenly spaced along the circumference. Intermediate reinforcing ribs 21 are provided within the guide tube 2 corresponding to the vertical slots 20, thereby enhancing the structural strength of the guide tube 2. Each set of heat exchange tube and corrugated baffle modules 3 includes several layers of corrugated baffles 30 and several heat exchange tubes 31. The heat exchange tubes 31 are respectively disposed within the layers of corrugated baffles 30. Each layer of corrugated baffles 30 includes a corrugated baffle 300 and a side strip 301 disposed around the edge of the corrugated baffle 300. A cone 302 is provided below the side strip 301. The cone 302 primarily serves to reduce the gap between the corrugated baffle 300 and the inner wall of the shell 1. In this embodiment, the cone 302 has a taper of 60°. The corrugated baffle 300 is arranged in a quarter circle. It is composed of several corrugated strips 3000 arranged in an opposite, staggered pattern and spot-welded, thereby increasing the gas's circulation time. A guide plate 304 is provided on the inner side strip 303 of the bottommost corrugated baffle 300. This guide plate 304 mates with the vertical groove 20 at the bottom of the guide riser 2. Within the housing 1, above the heat exchange tubes and corrugated baffle module 3, a support plate 5 is welded to the inner wall of the housing 1. The top of the heat exchange tube 31 is connected to the support plate 5 via a connecting rod 50 and a nut 51. A set of spacing adjustment mechanisms 6 is arranged between every two adjacent corrugated baffle layers 30. Each set of spacing adjustment mechanisms 6 includes: an adjusting screw 60, a fixing nut 61 and an adjusting nut 62. The adjusting screw 60 is provided with a supporting step portion 600. The adjusting screw 60 passes through the two adjacent upper and lower corrugated baffle layers 30 respectively. The fixing nut 61 is arranged at the upper free end of the adjusting screw 60, and the adjusting nut 62 is arranged at the lower free end of the adjusting screw 60. The lower corrugated baffle layer of the two adjacent upper and lower corrugated baffle layers is supported on the adjusting nut 62, and the upper corrugated baffle layer is supported on the supporting step portion 600 of the adjusting screw 60. The spacing between every two adjacent corrugated baffle layers can be adjusted by screwing the adjusting nut 62. When four heat exchange tubes and the corrugated baffle module 3 are assembled together, a gap 7 is provided between every two adjacent modules. The gap 7 is provided with an inclined thin plate 8 welded to the edge strip 301 of the corrugated baffle 300, thereby preventing airflow short circuit.

[0027] In summary, the utility model designs the heat exchange tubes and corrugated baffles, which are relatively complicated in process and installation, into a module structure, which not only greatly reduces the difficulty of transportation, but also, compared with the prior art of transporting each internal component to the site for installation, the utility model only needs to install several modules on site, which not only greatly improves the installation efficiency, but also ensures the installation accuracy of the assembly workers when assembling the modules on site by adding guide vertical pipes in the equipment and setting guide plates on the inner side strips of the corrugated baffles. In addition, considering that there is a gap between the modules after the modules are assembled, which will cause airflow short-circuiting, we have set an inclined thin plate in the gap.

[0028] The above embodiments are merely illustrative of the principles and effects of the present invention, as well as some embodiments of its application, and are not intended to limit the present invention. It should be noted that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
