Gas-solid reaction analysis device based on in-situ decoupling and analysis method

The invention discloses a gas-solid reaction analysis device based on in-situ decoupling and an analysis method, relates to an analysis device and an analysis method and particularly relates to a gas-solid reaction analysis device based on in-situ decoupling and an analysis method. The invention aims at solving the problem that the multi-stage high-temperature gas-solid reaction can not be better analyzed in the existing analysis device and method. The gas-solid reaction analysis device is characterized in that a gas detector is connected with a gas outlet of a reactor which is arranged in an electric heating furnace; the outer side wall of the reactor and the inner side wall of the electric heating furnace form a hearth cavity, a material outlet of an instantaneous feeder is connected with the reactor, and a temperature measuring part of a thermoelectric temperature controller is arranged in a reaction area of the reactor; a cooling medium channel is arranged in the electric heating furnace and a cooling medium enhances heat dissipation of the electric heating furnace by the cooling medium channel, so that the temperature of the reactor is rapidly reduced when a heating element does not work. The gas-solid reaction analysis device and the analysis method are used for gas-solid reaction analysis.
