Matrix type partition sampling and measuring device for accurate ammonia injection for denitration

The invention discloses a precise ammonia spraying matrix type partition sampling measuring device for denitration, and relates to the technical field of flue gas sampling devices.The precise ammonia spraying matrix type partition sampling measuring device comprises base plates, upper supporting columns and lower supporting columns, the base plates are symmetrically arranged, and the bottom ends of the lower supporting columns and the top ends of the upper supporting columns are fixedly connected to the middle positions of the base plates correspondingly; the top end of the lower supporting column is fixedly connected with a lifting mechanism, the lifting mechanism is fixedly connected with the bottom end of the upper supporting column, and the two ends of the base plate are movably connected with extension plates. Through the arranged lifting mechanism, a first servo motor is started to drive a first screw rod to rotate, due to the fact that the first screw rod is in threaded connection with a first edge blo
