Abstract
The invention discloses an experimental device capable of simulating the real environment of sandstorms or haze. The device is composed of a draught fan, a closed loop, a sandstorm generator or a haze generator, and an auxiliary draught fan, wherein the closed loop is composed of a left semi-annular air flue, a right semi-annular air flue, an auxiliary air flue and an experiment air flue, and the auxiliary air flue and the experiment air flue are communicated with the left semi-annular air flue and the right semi-annular air flue respectively. The sandstorm generator or the haze generator is communicated with the right semi-annular air flue through an air pipe, and the auxiliary draught fan is communicated with the sandstorm generator or the haze generator through an air pipe. According to the experimental device, the sandstorms can be simulated in a closed environment, the defect that sand dust or haze is discharged out of the device can be completely eliminated, and there are no negative experimental influences on the environment. According to the experimental device, the haze weather can be simulated by replacing the sandstorm generator with the haze generator so that relevant experiments can be performed.
