Automatic blast powder speed and pulverized coal concentration measuring device in pulverized coal conveying pipeline

The application discloses an automatic blast powder speed and pulverized coal concentration measuring device in a pulverized coal conveying pipeline. The automatic measuring device comprises a portable host, a plurality of groups of matching concentration measuring units and wind speed measuring units. The portable host, the concentration measurement units and the wind speed measurement units areconnected through power lines, signal lines or gas source pipes to realize separation of an analysis part and a measurement part of the automatic measuring device. The portable host is used for controlling the measurement process of the concentration measurement units and the wind speed measurement units. Each group of matching concentration measuring units and wind speed measuring units include one concentration measuring unit and one wind speed measuring unit to measure the blast powder speed and pulverized coal concentration of one same pulverized coal conveying pipeline. According to the invention, one-to-many mul
