An electrostatic on-line monitoring device for pipeline powder

Abstract

The invention provides a pipeline powder electrostatic on-line monitoring device, which includes a material conveying pipeline connected with the air conveying pipeline, the side wall of the material conveying pipeline is provided with a sealed chamber and a Faraday cage accommodation chamber for placing a Faraday cage, and the Faraday cage One side is an arc plate coaxial with the feeding pipeline, and the side opposite to the arc plate in the Faraday cage is fixed on the outer wall of the sealed chamber, and the bottom surface of the Faraday cage is provided with adjustable holes; the sealed chamber is equipped with an electric field induction plate, The electric field induction plate is connected with the Faraday cage through conductive bolts and fixed on the inner wall of the sealed room. An electrostatic tester is installed at a certain distance from the working surface of the electric field induction plate. Signal processing equipment is installed outside the sealed room. The signal processing equipment passes through The wires are connected to an electrostatic tester. As a material collection device, the Faraday cage leads the material charge signal to the electric field induction plate, and then uses the electrostatic tester and signal processing equipment to measure the static electricity of the pipeline powder in real time.

Description

technical field [0001] The invention relates to the field of petrochemical safety, in particular to an electrostatic on-line monitoring device for pipeline powder. Background technique [0002] The production process of polyolefin and polyester in the petrochemical industry adopts air conveying system to realize the conveying, blending and packaging of powder materials. High-insulation polyolefin, polyester particles and pipelines are frictionally electrified, and highly charged materials enter the silo through the pipeline, which may cause the wall of the silo to stick to the wall, and even a flash explosion accident of the silo. In this regard, the ion wind static elimination system is often used to eliminate and control the static electricity of the pipeline powder. However, when the powder static elimination equipment is used to eliminate the static electricity of the pipeline powder, it is necessary to obtain the static electricity of the pipeline material in advance to...
