Problems solved by technology
[0004] In the existing gasification agent distribution plate, there are small holes on the distribution plate, and a hood is arranged at the small hole. The existence of the hood prevents material leakage to a certain extent, but the existence of the hood makes the jet flow of the distribution plate relatively weak. It is easy to make the overall fluidization condition of the distribution plate area poor, resulting in a higher risk of material accumulation and slagging on the distribution plate surface

The invention relates to the technical field of coal gasification, in particular to a gasifying agent distribution plate and a fluidized bed gasifier. The gasifying agent distribution plate provided by the invention comprises a distribution plate body and an air caps, and a through hole is formed in the distribution plate body; the air cap is arranged at the through hole, a first air channel and asecond air channel which are communicated with the through hole are formed in the air cap, the first air channel is provided with a first jet flow opening formed in the top of the air cap, the secondair channel is provided with a second jet flow opening formed in the bottom of the air cap, and the second jet flow opening faces the distribution plate body. According to the gasifying agent distribution plate, the first jet flow opening of the first air channel is formed in the top of the air cap, and the second jet flow opening of the second air channel is formed in the bottom of the air cap,so that fluidization in the gasification hearth and the gasifying agent distribution plate is enhanced, and the risk of material accumulation and slagging in a gasification hearth and on the gasification agent distribution plate, especially at the bottom of a hood, is effectively reduced.
Description
technical field [0001] The invention relates to the technical field of coal gasification, in particular to a gasification agent distribution plate and a fluidized bed gasification furnace. Background technique [0002] Fluidized bed coal gasification technology is one of the earliest industrialized gasification processes. The process is that the raw coal maintains continuous boiling and suspension state movement under the action of bottom-up gasification agent, and rapidly mixes and exchanges heat. gasification technology. [0003] As the main component of the fluidized bed equipment, the gasification agent distribution plate plays an important role in uniform gas distribution and supporting solid particles. Its shape and structure greatly affect the production and operation performance of the equipment such as heat transfer and mass transfer. Specifically, the functions of the gasification agent distribution plate include: uniform distribution of the gasification agent flu...
