Abstract

The application discloses an electric dust removal optimization ash conveying pipeline concentration measuring device, and relates to the technical field of electric dust removal. The device comprises two opposite ash conveying pipeline bodies and a dust concentration measuring instrument, and further comprises a rectifying mechanism arranged on the detection pipe and used for rectifying and uniformly dispersing dust flowing through the detection area of the dust concentration measuring instrument, and a crushing mechanism arranged on the rectifying mechanism and used for crushing agglomerated dust. The rectifying mechanism comprises a rectifying ring arranged on the detection pipe near the dust conveying direction. The rectifying ring is fixedly connected with a plurality of rectifying plates arranged in a staggered mode. The electric dust removal optimization ash conveying pipeline concentration measuring device can realize crushing of agglomerated dust caused by electrostatic adsorption, rectification and uniform dispersion of the crushed dust through cooperation of the rotating assembly and the driving assembly, so that the dust is uniformly distributed in the airflow.
