摘要

为了解决木材加工设施中的火灾和粉尘爆炸问题，研究人员对气吹式清洁操作过程中木屑颗粒和空气软管上的荷电行为进行了调查。有效功函数、单位重量和表面粗糙度是影响空气软管上电荷积累的关键参数。使用速度较低和含水量较高的压缩空气可以减少空气中木质颗粒上的电荷产生。颗粒大小、形状和木材种类会影响木屑的电荷行为。导电表面和水分有助于电荷从木屑颗粒上快速消散。

Experimental study of electrostatic charging related to prevention of fire and dust explosions in wood processing facilities

To address the concern of fire and dust explosions in wood processing facilities, the charging behavior on wood dust particles and air hoses during the air-blow cleaning operation were investigated. The effective work function, unit weight and surface roughness were key parameters influencing the charge accumulation on air hoses. The use of compressed air with lower velocity and higher moisture content could reduce the charge generation on airborne wood particles. Particle size, shape and wood species affect the charging behavior of wood dust. Conductive surface and moisture could help charges to be dissipated fast from wood dust particles.
