Powder fluidizing-delivering spraying pot for experiment

The utility model discloses a powder fluidizing-delivering spraying pot for experiment comprising a spraying pot body, an inputting pipe of gas loading, inputting pipes of fluidizing gas and a powder outputting pipe. The inputting pipe of gas loading is horizontally provided on the bottom portion of a fluidizing spraying pot. The powder outputting pipe is inserted from the top of the fluidizing spraying pot body and positioned on the center of the inner portion of the spraying pot body. The inputting pipes of fluidizing gas are symmetrically in inserting providing on the two sides of the powder outputting pipe in perpendicular. The delivering gas horizontally enters into the pot body from the bottom of the spraying pot by certain pressure. The fluidizing gas is perpendicularly and downward enters into the fluidizing spraying pot and forms a big rotational flow in the pot body to improve the fluidizing state of the powder (coal powder) in the pot body. Meanwhile, the powder outputting pipe is directly inserted into the inner portion of the powder (coal powder) from the top portion of the pot to enable the powder (coal powder) to keep a stable solid-gas proportion in the entire gas delivering process. The powder gas current is even, the flowing state is stable, the pulsation phenomenon does not exist, the power-gas concentration (solid-gas proportion) always keeps stable and also the solid-gas proportion of the powder can be arbitrarily adjusted according to the requirements in the delivering process.
