Pipeline type powder bunker electrostatic remover

Abstract

In the present invention, spray points of positive ion and negative ion electrodischarging are electric-connected with positive ion high voltage module and negative high voltage module which are connected at output end of voltage regulator, the spray points is passed through into material conveying pipe and is set on material conveying pipe through its base, spray point base has positive pressure ventilation cavity which is connected through to positive pressure gas chamber.

Description

Technical field [0001] The invention relates to a static elimination device used in a pipeline for conveying powder materials in the petrochemical industry. Background technique [0002] In the petrochemical industry, in the process of blowing polyolefin and other powder materials by air, there are inevitably mutual collisions and frictions, which cause the materials to generate and carry a large amount of static charge, especially for large silos in the petrochemical industry, which induces powder discharge. The required critical mass is relatively small, the discharge frequency is high, and with the increase of materials in the bin, the concentration of combustible gas above the stockpile increases, and the energy required for ignition decreases, which can easily induce dust explosion and combustion in the bin, and even cause A major safety accident that resulted in the destruction of the aircraft. In order to effectively control the occurrence of explosion accidents caus...

Problems solved by technology

In order to effectively control the occurrence of explosion accidents caused by static electricity, people always give priority to how to suppress and eliminate static electricity. Large, uneven distribution, coupled with the inconsistency of the critical charge-to-mass ratio in each working environment, and many other reasons, it is impossible for AC or DC electrical appliances to achieve the ideal efficiency of electricity removal. This problem of static electricity elimination that people have been concerned about for a long time has not been found. Effective technical means, but still rely on process operating conditions and combustible gas control to reduce the probability of explosion, but this method has many influencing links, such as process fluctuations, poor maintenance, etc., and it is very easy to get out of control. Not high enough to avoid accidents
