木材加工粉尘问题解决方案

木材加工粉尘问题解决方案

1.提出问题

在木材加工厂的锯切与打磨车间,未安装除尘系统时存在以下问题:

1.1.    粉尘污染严重:车间内粉尘浓度高达250 mg/m³,工人健康风险突出。

1.2.    设备磨损加剧:粗颗粒粉尘进入电机和传动系统,导致设备故障率增加30%,年维护成本上约18万元。

2.解决方案 
采用多级除尘系统:旋风预分离+脉冲袋式精滤

2.1.    旋风预分离 选用JRS-6.0型旋风除尘器,入口风速18 m/s,处理风量12,000 m³/h,分离粒径≥15μm的粗颗粒,除尘效率85%。

2.2.    脉冲袋式精滤 配置PPC96-8型脉冲袋式除尘器,滤袋材质PTFE覆膜涤纶,过滤精度0.3μm,耐温120℃。 

3.实施效果
