Abstract
Description
[Technical field]
[0001] The invention relates to the field of fluidized bed devices, and in particular to a module structure of a heat exchange tube and a corrugated baffle. [Background technology]
[0002] Fluidized bed, abbreviated as fluidized bed, is a reactor that uses gas or liquid to pass through a granular solid layer to put solid particles in 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 the fluidized bed below 30,000 tons is about 3m, and the diameter can reach 5m with the transportation of accessories, so it can be transported by road. Therefore, during manufacturing, we can manufacture the entire fluidized bed device in the factory and then transport it to the customer's site. However, with the development of technology, the fluidized bed device is getting larger and larger. The diameter of some fluidized bed devices has reached 5∽7m, and the diameter can reach 10∽12m with the transportation of accessories. 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 prior art. First, the internal parts of the fluidized bed are made in the manufacturing plant, and then workers are sent to the customer's site to assemble them, which leads to a huge workload of on-site assembly at the customer's site. Taking a fluidized bed device with a diameter of 5m and a transportation diameter of 10m for accessories as an example, it takes about 30 workers to install it on the customer's site for 180 days. If there is a lot of rain, it will be postponed. Therefore, the equipment manufacturing cost is significantly increased and the work efficiency is reduced. Therefore, we thought about how to make the heat exchange tubes and corrugated baffles into a module structure in the manufacturing plant, and then transport the module structure to the site for workers to assemble several module structures. This not only solves the transportation problem, but also greatly improves the assembly efficiency of workers at the customer's site. The present invention aims to provide such a module structure of heat exchange tubes and corrugated baffles. [Summary of the invention]

A plurality of heat exchange tubes 2 are respectively inserted into the plurality of corrugated baffle layers 1. Each corrugated baffle layer 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 formed by spot welding a plurality of corrugated strip plate single pieces 100 arranged in opposite oblique directions, 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 at the tube hole. A guide plate 103 is provided at the inner side strip 102 of the corrugated baffle 10 at the bottom, and the guide plate 103 is used for guidance during on-site assembly. In this embodiment, the cone 12 has a taper of 60°, and 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 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 at the bottom of a plurality of heat exchange tubes 2. The top positioning frame 32 is provided with a plurality of first grating bars (not shown) and a first sleeve 310 is provided at the bottom of the hanger 30. The bottom support frame 31 is supported at the bottom of a plurality of heat exchange tubes 2. 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 from several second grid bars (not shown) through a second fixing member. 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 present invention designs the top positioning frame 32 and the bottom supporting frame 31 to be a detachable structure is that after the module 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 supporting frame 31 are all to be disassembled.
[0023] A set of spacing adjustment mechanisms 4 is arranged between every two adjacent corrugated baffle layers 1, and each set of spacing adjustment mechanisms 4 includes: an adjusting screw 40, a fixing nut 41 and an adjusting nut 42, wherein the adjusting screw 40 is provided with a supporting step 400, and the adjusting screw 40 passes through two upper and lower adjacent corrugated baffle layers 1 respectively, wherein the fixing nut 41 is arranged at the upper free end of the adjusting screw 40, and the adjusting nut 42 is arranged at the lower free end of the adjusting screw 40, wherein the lower corrugated baffle layer of the upper and lower adjacent corrugated baffle layers is supported on the adjusting nut 42, and the upper corrugated baffle layer is supported on the supporting step 400 of the adjusting screw 40. The spacing between every two adjacent corrugated baffle layers 1 can be adjusted by screwing 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, which can also realize the present invention.
[0024] During on-site assembly at the customer's unit, the lifting rod 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 lifting rod is tightened, and then the bottom support frame is 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, and finally the lifting rod is pulled out from the corrugated baffle layer.
[0025] In summary, the present invention not only greatly reduces the transportation pressure but also greatly improves the assembly efficiency when assembling at the customer unit by manufacturing the heat exchange tube and the corrugated baffle into a module structure.
[0026] The above-mentioned embodiments are only illustrative of the principles and effects of the invention, as well as some embodiments of its application, and are not intended to limit the invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the invention, and all of these belong to the protection scope of the invention.
