Description

Technical Field

[0001] The utility model relates to the technical field of coal gasifier air inlet, in particular to an air inlet structure for a coal gasifier. Background Art

[0002] A coal gasifier is a device used to produce coal gas by reacting coal with a gasifying agent (such as air or steam).

[0003] The working principle of the gasifier is to add solid raw coal from the top of the furnace. As the furnace runs, the coal moves downward and meets the gasification agent countercurrently entering from the bottom of the furnace. At the same time, it is heated by the high-temperature gas in the fuel layer at the bottom of the furnace, thereby causing physical and chemical reactions to produce raw coal gas.

[0004] The furnace body is usually cylindrical. The outer shell can be made of steel plates or bricks, lined with refractory bricks, and equipped with charging equipment, blast ducts (air inlet structure) and gas pipelines.

[0005] The air intake structure is generally composed of a fan, a pipe, a hood seat and a hood assembly. When in use, the fan is started to intake air through the pipe, and then the gas (gasifying agent) is sent into the furnace through the hood seat and the hood assembly.

[0006] However, when in use, the fan is generally directly exposed to the outside and fixed to the pipe by screws, which makes it inconvenient to operate during replacement and maintenance. Moreover, when not in use, the fan is exposed to the outside for a long time and will be affected by the sun and rain, which affects the service life of the fan. Utility Model Content

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] A gasifier air inlet structure includes a furnace body 10, a plurality of support legs 11 fixed to the bottom of the furnace body 10, a hood seat 20 disposed inside the furnace body 10, and a hood assembly 30 disposed on the top of the hood seat 20. The furnace body 10, support legs 11, hood seat 20, and hood assembly 30 are all existing structures of a gasifier;

[0038] In the examples of this application, please refer to Figure 1 One end of the air inlet pipe 40 is provided inside the hood seat 20 and is connected in an existing manner. The other end of the air inlet pipe 40 extends to the side of the furnace body 10 and is connected to the fan 60 through a connecting pipe 80. A fan seat 70 is fixed to the bottom of the fan 60, and a plurality of universal wheels 71 are fixed to the bottom of the fan seat 70. When in use, the fan 60 can be started normally to let air in through the air inlet pipe 40 to complete the existing air intake function. When not in use or when the fan 60 needs to be replaced, the fan seat 70 is slid to move the fan 60 away from the air inlet pipe 40, so that the connecting pipe 80 is no longer connected, and the process is completed. It no longer needs to be fixed here, which is not only convenient for disassembly and replacement, but also can avoid the situation where it needs to be fixed here when not in use, and has a longer service life.

[0039] In the above example, see Figure 1 and 2The connecting pipe 80 includes a limiting pipe 81 fixed to the air outlet end of the fan 60. The limiting pipe 81 is fixedly connected to the plug-in pipe 82. The plug-in pipe 82 can be plugged into the interior of the air inlet pipe 40, and a conical surface is provided on the side away from the fan 60. A plurality of sealing rings 83 are sleeved on the outside of the plug-in pipe 82, and a gasket 84 is fixed on the side of the limiting pipe 81 away from the fan 60. When connecting, the plug-in pipe 82 is inserted into the interior of the air inlet pipe 40 to complete the connection, and vice versa, it can be taken out. The operation is simple and easy to disassemble and assemble.

[0040] For further examples, please refer to Figure 1 and 2 In order to ensure the stability of the air inlet duct 40, a fixing structure 50 is set between the air inlet duct 40 and the support leg 11. Specifically, the fixing structure 50 includes a pipe sleeve 51 fixedly sleeved on the outside of the air inlet duct 40. The pipe sleeve 51 is fixedly connected to a plurality of fixing rods 52 fixedly connected to the support leg 11. The air inlet duct 40 and the support leg 11 are fixed by the pipe sleeve 51 and the fixing rods 52.

[0041] At the same time, in order to increase the stability after connection and avoid accidental loosening, please refer to Figure 1 and 2 A connecting structure 90 is provided between the limiting tube 81 and the air inlet pipe 40. The connecting structure 90 includes two fixed blocks 91 fixed to the top of the limiting tube 81. One end of a movable rod 92 is rotatably connected between the two fixed blocks 91 through a rotating shaft 93. The other end of the movable rod 92 is fixed with a limiting block 94. A connecting block 95 is fixed to the top of the air inlet pipe 40. A limiting groove 96 that is compatible with the movable rod 92 is opened on the top of the connecting block 95. After the connection, the movable rod 92 is rotated so that it rests on the inside of the limiting groove 96. Then, the restriction can be completed by the limiting block 94 and the connecting block 95 to prevent the limiting tube 81 and the plug-in tube 82 from loosening from the air inlet pipe 40. Otherwise, the connection can be canceled and then it can be disassembled and assembled normally.
