[0028] The upper part of the tube cavity of the dust removal tube 100 is a boundary area, the part close to the boundary area is a low-concentration dust area, and the part far away from the low-concentration dust area is a high-concentration dust area, wherein the electrostatic sensor 400 is located in the low-concentration dust area to facilitate better detection of dust in the dust removal tube 100.

A threaded hole 312 is provided at the top of the connecting flange 311, and there are four threaded holes 312. The four threaded holes 312 are distributed in a circular array at the top of the connecting flange 311, so that the sensor 400 can be fixed by using four bolts 003 to penetrate the threaded holes of the flange 002 and the connecting flange 311, so as to maintain the stability of the electrostatic sensor 400.
