Kiln flow field simulation device

The utility model provides a kiln flow field simulation device. A kiln flow field simulation device comprises a model main body; a simulated flue gas generation assembly; the tracing assembly comprises a plurality of laser generators used for generating laser and a plurality of prisms used for at least partially changing a laser light path, the prisms are arranged in multiple groups, each laser generator corresponds to one group of prisms, and the multiple groups of prisms are distributed on two side wall surfaces of an inner cavity of the model shell; at least part of a laser initial light path generated by the laser generator penetrates through the simulated flue gas inlet, and at least part of each prism is located on the laser initial light path generated by the laser generator. According to the utility model, the tracer particles are mixed into the air to be used as simulated flue gas, and the flow track of the simulated flue gas in the model main body is visually displayed through laser irradiation by u
