Abstract
Description
Technical field
[0001] The utility model relates to the field of fluidized bed devices, in particular to a module structure of a heat exchange tube and a corrugated baffle. [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 modular structure of heat exchange tubes and corrugated baffles. [Utility Model Content]

[0020] The module structure of the heat exchange tube and the corrugated baffle of the present invention is further described in detail below through specific embodiments.
[0021] Ginseng Figures 1 to 5As shown, a modular structure of heat exchange tubes and corrugated baffles includes: several layers of corrugated baffles 1, several heat exchange tubes 2, hanger assemblies 3, and several groups of spacing adjustment mechanisms 4. Several heat exchange tubes 2 are respectively inserted into the several layers of corrugated baffles 1. Each layer of corrugated baffles 1 includes a corrugated baffle 10, a side strip 11 arranged around the edge of the corrugated baffle 10, and a cone 12 arranged below the side strip. The corrugated baffle 10 is made of several corrugated strip plates 100 arranged in opposite oblique directions and spot welded together, thereby increasing the circulation time of the gas. The corrugated baffle 10 is provided with a tube hole for the heat exchange tube 2 to pass through, and a short tube 101 is welded to the tube hole. A guide plate 103 is provided on the inner side strip 102 of the corrugated baffle 10 at the bottom. The guide plate 103 is used for guidance during on-site assembly. In this embodiment, the cone 12 has a taper of 60°. The main function of the cone 12 is to reduce the gap between the corrugated baffle 10 and the inner wall of the fluidized bed cylinder.
[0022] The hanger assembly 3 includes: a plurality of hangers 30, a bottom support frame 31 and a top positioning frame 32. The plurality of hangers 30 are respectively inserted into a plurality of layers of corrugated baffle layers 1. Nuts 33 are provided at the bottom of the plurality of hangers 30. The bottom support frame 31 is sleeved at the bottom position of the plurality of hangers 30 and is located above the nut 33. The bottom support frame 31 is assembled by a plurality of first grid bars (not shown) through a first fixing member. The bottom support frame 31 is welded with a first sleeve 310 at the position corresponding to the hanger 30. The first sleeve sleeve 310 is provided at the bottom of the hanger 30. The bottom support frame 31 is supported on the bottom of the plurality of heat exchange tubes 2. The top positioning frame The frame 32 is welded to the top positions of several hangers 30 and positions the tops of several heat exchange tubes 2. The top positioning frame 32 is assembled by several second grid bars (not shown) through second fixing parts. The top positioning frame 32 is welded with a second sleeve 320 at the position corresponding to the hanger 30. The second sleeve 320 is sleeved on the top of the hanger 30 and welded to the hanger 30. The reason why the top positioning frame 32 and the bottom support frame 31 are designed to be detachable in the present invention is that after the modular structure of the heat exchange tube and the corrugated baffle is assembled on site and hoisted into the cylinder of the fluidized bed, the hanger, the top positioning frame 32 and the bottom support frame 31 are all to be disassembled.
[0023] A spacing adjustment mechanism 4 is provided between each two adjacent corrugated baffle layers 1. Each spacing adjustment mechanism 4 includes an adjusting screw 40, a fixing nut 41, and an adjusting nut 42. The adjusting screw 40 is provided with a supporting step 400. The adjusting screw 40 passes through the two adjacent corrugated baffle layers 1, respectively.

The lower corrugated baffle layer is supported on the adjusting nut 42, while the upper corrugated baffle layer is supported on the supporting step 400 of the adjusting screw 40. The spacing between each two adjacent corrugated baffle layers 1 can be adjusted by turning the adjusting nut 42. In this embodiment, the corrugated baffle layer 1 is arranged in a quarter circle, that is, at the assembly site, the module structure of four heat exchange tubes and corrugated baffles in this embodiment can be assembled into the cylinder of the fluidized bed device. Of course, in other embodiments, the corrugated baffle layer 1 can also be arranged in a third circle or a fifth circle, and the present invention can also be implemented.
[0024] During on-site assembly at the customer's unit, the boom is lifted by the lifting equipment. At the same time, the entire module structure of the heat exchange tube and the corrugated baffle is lifted, and then installed into the cylinder of the on-site fluidized bed. After installation, the nut at the bottom of the boom is tightened, and the bottom support frame is then disassembled and transported out of the equipment through the manhole of the cylinder. Then the top positioning frame is disassembled and transported out of the equipment through the manhole of the cylinder. Finally, the boom is pulled out from the corrugated baffle layer.
[0025] In summary, the present invention, by manufacturing the heat exchange tubes and the corrugated baffles into a module structure, not only greatly reduces the transportation pressure, but also greatly improves the assembly efficiency during assembly at the customer's unit.
[0026] 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.
