Micro fluidized bed reaction device applied to thermogravimetric analysis

The invention discloses a micro fluidized bed device applied to thermogravimetric analysis, and belongs to the technical field of thermogravimetric analysis. The device comprises a reactor and an instantaneous feeder. The reactor sequentially comprises a base, a first air inlet, a pressure tapping, a preheating section, an air distribution plate, a reaction section, a diverging section, a thermocouple connecting pipe, a frosted opening, an air outlet and a filter from bottom to top. The instantaneous feeder sequentially comprises a feeding pipe, a frosted plug, a second air inlet, an adjustable throttle valve, a stock bin and a horizontal air inlet from bottom to top. The thermocouple connecting pipe and the air outlet are located on the two sides of the frosted opening, and a thermocouplesealing joint is arranged at one end of the thermocouple connecting pipe; and the frosted opening of the reactor is matched with the frosted plug of the feeder for use. According to the invention, the micro fluidized bed rea
