Example Embodiment
[0033] The present invention will be further described below in conjunction with the drawings and embodiments.
[0034] See Figure 1 and figure 2 , Install a probe 2 in the upstream and downstream of the pneumatic conveying pipe 1 (the distance between the two in this embodiment is 50mm), install a piezoelectric sensor 4 on the outside of the pipe where the probe 2 is located, and connect the probe 2 with the electrostatic detection circuit 3Connect. The static electricity detection signal output by the static electricity detection circuit 3 and the resonance signal output by the piezoelectric sensor 4 through the resonance signal conditioning circuit are connected to the data acquisition module 6 and the analysis calculation module 7.
[0035] The working principle of the combined measurement method of electrostatic detection circuit and piezoelectric sensor for gas-solid two-phase flow parameters is as follows: in pneumatic transmission, due to the collision between solid particl...
