Abstract

The invention discloses dust environment simulation equipment, which comprises a dust generation device, a wind tunnel, a dust collector and a fan. The wind tunnel comprises a wind inlet section, a turbulence section and a testing section. The inner passage of the wind inlet section is horn-shaped. The dust outlet of the dust generation device is formed at the large-aperture end of the wind inlet section. The small-aperture end of the wind inlet section is communicated with the turbulence section. A turbulence structure is arranged on the turbulence section. One end of the testing section is communicated with the turbulence section and the other end of the testing section is communicated with the dust collector. The fan is communicated with the dust collector. An observation window which can be opened and closed is arranged on the testing section. A dust concentration sensor which is used for detecting internal dust concentration is arranged in the testing section and is communicated with an electric control device. The electric control device is electrically connected with the dust generation device. The simulation equipment can simulate a uniform-concentration dust environment, the concentration is adjustable and testing results obtained through product testing by using the simulation equipment are more accurate.
