Embodiment Construction

[0015] figure 1 It is the embodiment of the real-time online monitor for powder static electricity of the present invention. The device adopts the principle of Faraday cylinder for real-time electrostatic monitoring of powder materials. Specifically, a section of the conveying cylinder is used as a monitor as a whole. The device includes a metal inner cylinder 5 in contact with the powder material, which is concentrically arranged with the metal inner cylinder 5 The metal outer cylinder, and the insulating layer 3 arranged between the inner and outer cylinders, at least one position of the insulating layer 3 is provided with a point connection device 6, one end of which is connected to the metal inner cylinder 5, and the other end protrudes from the insulating layer 3 and is exposed to the metal In the opening on the wall of the outer cylinder 4. The device is installed on the pipeline close to the feed of the silo, and the inner diameter is consistent with the inner diameter...

Abstract

The invention relates to a real-time electrostatic monitoring device for powder. The monitoring device serving as one part of a powder conveying pipe comprises an inner conducting cylinder (5) and anouter conducting cylinder (4); an insulator layer (3) is arranged between the inner conducting cylinder (5) and the outer conducting cylinder (4); the inner conducting cylinder (5) are in contact withthe powder directly. When being in use, the monitoring device is installed at a material conveying pipe and is capable of monitoring the electrostatic charge number in the conveying pipe in real time.

Description

technical field [0001] The invention is a powder electrostatic monitor applied in the petrochemical industry, in particular a device for real-time monitoring of the electrostatic value accumulated by the powder in the conveying pipeline. Background technique [0002] The raw materials of petrochemical industry products are mostly powder materials (such as polyolefins). During the pneumatic conveying process, the powder materials are in a state of rapid flow or shaking, vibration, etc., and collisions, separations, and frictions with pipes and walls will occur. Make the powder material carry a considerable amount of static electricity. These powder materials with static electricity are either adsorbed on the inner wall or aggregated into blocks, which directly affects the efficiency of transportation. At the same time, as the powder static electricity continues to accumulate and is difficult to dissipate, it also seriously threatens the warehouse Once the electrostatic voltag...
