The invention discloses a pipeline powder electrostatic monitoring device, which mainly includes a stainless steel feeding pipe with the same size as the air delivery pipeline, a sealed chamber, a Faraday cylinder with adjustable hole size at the bottom, an electric field induction plate, an electrostatic tester and a signal Handling equipment. A sealed chamber is arranged on the feed pipe, and a Faraday cage is arranged inside the sealed chamber, and a baffle plate for adjusting the size of the hole is installed at the bottom of the Faraday cage; an electric field induction plate is arranged outside the Faraday cage, and a An electrostatic tester for measuring the electrostatic signal on the electric field induction plate is arranged at a place facing the working surface of the electric field induction plate inside and at a certain distance, and the electrostatic tester is used for converting the measured electrostatic signal into a material belt The signal processing equipment connection of the electric quantity signal. The invention can be used for on-line static monitoring of materials in air conveying pipelines of petrochemical polyolefin and polyester plants, and has the advantages of continuous, real-time, high-efficiency, fast and accurate measurement of static electricity, and the like.
Description
technical field [0001] The invention relates to an electrostatic monitoring device for air-conveyed materials in the petrochemical industry, in particular to a pipeline powder electrostatic monitoring device which can realize real-time monitoring of pipeline powder static electricity. Background technique [0002] Petrochemical devices, such as polyolefin and polyester production devices, use air delivery systems to realize the production, transportation and packaging of powder materials. High-insulation polyolefin, polyester particles and pipes are frictionally electrified, and highly charged materials enter the silo through the pipes, which may cause the silo to stick to the wall or even cause the silo to explode. For this reason, it is necessary to monitor the electrostatic charge of the materials entering the silo to prevent the abnormal increase of the static electricity of the materials entering the silo. [0003] The charge carried by the wind-blown object belongs to...
