Description

Technical Field

[0001] This utility model relates to the field of fluidized bed technology, and more specifically, to a uniformly fluidized bed. Background Technology

[0002] Circulating fluidized bed combustion is a clean coal combustion technology. Due to its outstanding advantages such as wide fuel adaptability, high combustion efficiency, low nitrogen oxide emissions, low-cost limestone in-furnace desulfurization, large load adjustment ratio, and rapid load adjustment, it has been widely used worldwide, and large-capacity circulating fluidized bed boilers have been accepted by the power generation industry. A cyclone separator is a device used to separate gas-solid or liquid-solid systems. The main function of a cyclone separator is to remove as many solid particles and droplets as possible from the conveyed gas, achieving gas-solid-liquid separation to ensure the normal operation of pipelines and equipment.

[0003] Among them, the patent with announcement number CN204962738U discloses a circulating fluidized bed boiler. The circulating fluidized bed boiler includes a furnace, and the interior of the furnace has a dilute phase zone and a dense phase zone formed sequentially from top to bottom. The upper part of the furnace is provided with a central flue gas outlet and a side flue gas outlet. The central flue gas outlet is located in the middle of the furnace in the horizontal direction, and the side flue gas outlet is located on the side of the furnace in the horizontal direction. The central flue gas outlet is connected to the flue gas inlet of the central cyclone separator, and the side flue gas outlet is connected to the flue gas inlet of the side cyclone separator. The material outlet of the central cyclone separator is connected to the side of the dense phase zone in the horizontal direction, and the material outlet of the side cyclone separator is connected to the middle of the dense phase zone in the horizontal direction.

[0004] In use, this structure connects the material outlet of the central cyclone separator to the horizontal side of the dense phase zone, and the material outlet of the side cyclone separator to the horizontal center of the dense phase zone. This allows the material separated by the side cyclone separator to be supplied to the horizontal center of the dense phase zone for complete combustion. At the same time, because the central cyclone separator separates less material, the material supplied to the horizontal side of the dense phase zone is correspondingly reduced, thereby lowering the burnout pressure on that side. However, this structure is not easy to divert material during use and cannot achieve bidirectional heating and combustion of the material, resulting in poor fluidization. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a uniformly fluidized bed, which aims to solve the problems mentioned in the background art.

[0006] This utility model provides the following technical solution: a uniformly fluidized bed, including a fluidizing box, wherein a material distribution component is provided on the fluidizing box;

[0007] The material distribution assembly includes a fluidized bed body disposed inside a fluidized box, and a fluidized heat insulation cavity is provided in the middle of the fluidized box;

[0008] The fluidized bed body is provided with a number of reinforcing crossbars inside, and the multiple reinforcing crossbars are arranged side by side, and a number of flow diversion and conduction components are provided between each pair of adjacent reinforcing crossbars;

[0009] The fluidized bed is provided with a reinforcing baffle at the top of its inner cavity, and a number of controllers are embedded in the reinforcing baffle. Each of the controllers has a first burner at its bottom.

[0011] Optionally, in one possible implementation, support rails are provided on both sides of the bottom of the fluidized bed body, and each support rail is bolted to the inner wall of the fluidization insulation chamber. The fluidized bed body is slidably connected to the support rails. A support frame is provided on the top of the fluidized bed body, and the support frame is bolted to the fluidization box. One end of the reinforcing crossbar has an installation groove, and a temperature sensor is embedded in the installation groove. The temperature sensor is detachably connected to the support frame by bolts. Two second burners are provided at the bottom of the fluidized bed body, and each second burner is detachably connected to the fluidization box by bolts. Support legs are bolted to the four corners of the bottom of the fluidization box. Multiple reinforcing crossbars are inserted into the fluidized bed body.

[0012] As can be seen, in the above technical solution, through the setting of various reinforcing crossbars and diversion and conduction components, when the material is added into the fluidized bed body, the material can be diverted through various diversion and conduction components to avoid the material from piling up together. At the same time, heat can also be conducted through the diversion and conduction components, making it easier for the material to be heated and burned evenly, thereby improving the fluidization efficiency and effect.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] By setting up a material distribution component, the material is added into the fluidized bed body, and the top of the fluidized bed body is burned by the controller and the first burner, while the bottom of the fluidized bed body is burned by the second burner, thus realizing the function of bidirectional combustion of the material in the fluidized bed body.

[0015] Furthermore, with the addition of various reinforcing crossbars and diversion and conduction components, when materials are added into the fluidized bed body, they can be diverted through these components, preventing material from piling up. At the same time, heat can be conducted through these components, making it easier for the materials to be heated and burned evenly, thus improving fluidization efficiency and effect.

[0023] As attached Figure 1 - Figure 4The fluidized bed shown is a uniformly fluidized bed. Through the material distribution component set on the fluidization box 1, the material is added into the fluidized bed body 2. The top of the fluidized bed body 2 is burned by the controller 6 and the first burner 7, and the bottom of the fluidized bed body 2 is burned by the second burner 11. This realizes the function of bidirectional combustion of the material in the fluidized bed body 2. Furthermore, through the setting of various reinforcing crossbars 3 and flow diversion and conduction components 4, when the material is added into the fluidized bed body 2, the material can be diverted through the various flow diversion and conduction components 4 to avoid the material from piling up. At the same time, heat conduction can also be carried out through the flow diversion and conduction components 4, which facilitates uniform heating and combustion of the material, thereby improving fluidization efficiency and effect. The specific structural setting of the component is as follows.

[0024] The material distribution assembly includes a fluidized bed body 2 disposed in a fluidized box 1, and a fluidized insulation cavity 13 is provided in the middle of the fluidized box 1;

[0025] The fluidized bed body 2 has several reinforcing crossbars 3 inside, and the multiple reinforcing crossbars 3 are arranged side by side, and several flow diversion and conduction components 4 are arranged between each pair of adjacent reinforcing crossbars 3;

[0026] A reinforcing baffle 5 is provided at the top of the inner cavity of the fluidized insulation chamber 13. Several controllers 6 are embedded in the reinforcing baffle 5, and a first burner 7 is provided at the bottom of each controller 6.

[0027] Support rails 8 are provided on both sides of the bottom of the fluidized bed body 2, and each support rail 8 is bolted to the inner wall of the fluidized insulation chamber 13. The fluidized bed body 2 is slidably connected to the support rails 8. A support frame 9 is provided on the top of the fluidized bed body 2. The support frame 9 is bolted to the fluidized box 1. One end of the reinforcing crossbar 3 is provided with an installation groove. A temperature sensor 10 is embedded in the installation groove. The temperature sensor 10 is detachably connected to the support frame 9 by bolts. Two second burners 11 are provided at the bottom of the fluidized bed body 2, and each second burner 11 is detachably connected to the fluidized box 1 by bolts. Support legs 12 are bolted to the four corners of the bottom of the fluidized box 1. Multiple reinforcing crossbars 3 are inserted into the fluidized bed body 2.

[0028] According to the above structure, when in use, the staff installs the device at the designated location. When fluidizing the material, the material is added into the fluidized bed body 2. The top of the fluidized bed body 2 is burned by the controller 6 and the first burner 7, while the bottom of the fluidized bed body 2 is burned by the second burner 11, so as to realize the function of bidirectional combustion of the material in the fluidized bed body 2.

[0029] Furthermore, with the addition of various reinforcing crossbars 3 and diversion and conduction components 4, when the material is added into the fluidized bed body 2, the material can be diverted through various diversion and conduction components 4 to avoid the material from piling up together. At the same time, heat can also be conducted through the diversion and conduction components 4, making it easier for the material to be heated and burned evenly, thus improving the fluidization efficiency and effect.

[0030] Furthermore, the fluidized bed body 2 can be pulled out from the fluidized insulation cavity 13 via the support rail 8, so as to facilitate cleaning and maintenance of the fluidized bed body 2. At the same time, the temperature inside the fluidized insulation cavity 13 can be detected by the temperature sensor 10, so as to facilitate the staff to adjust it.

[0031] Unlike existing technologies, this application discloses a uniformly fluidized bed. By adding material into the fluidized bed body 2, the top of the fluidized bed body 2 is burned by the controller 6 and the first burner 7, while the bottom of the fluidized bed body 2 is burned by the second burner 11. This achieves bidirectional combustion of the material within the fluidized bed body 2. Furthermore, through the setting of various reinforcing crossbars 3 and flow diversion components 4, when the material is added into the fluidized bed body 2, it can be diverted through the various flow diversion components 4 to prevent the material from accumulating together. At the same time, heat conduction can also be carried out through the flow diversion components 4, which facilitates uniform heating and combustion of the material, thereby improving fluidization efficiency and effect.
