摘要
为保障车间电焊作业人员身体健康,研究通风排尘净化装置的实际使用效果,对某车辆段2套可移动式局部通风排尘净化系统的实际使用效果及其他卫生技术性能进行验收测评.结果显示:2套系统开启后均能达到去除主要污染物所需控制风速,对电焊烟尘均有较好的排除和净化作用,排尘效率分别为73.81%和71.43%,对电焊烟尘净化效率均达到97%以上.经检验,电焊烟尘浓度在开机前后及净化前后差异有显著性意义(H=0,P＜0.01).2套系统体积小巧、形式适宜,方便移动,系统风量适中,操作口风量分配经济合理,符合通风排尘、净化要求.系统运行耗材成本低,系统维护简单、方便,是可推广使用的通风排尘净化系统.
Abstract
In order to ensure the health of personnel engaged in welding operations in the workshop,this study investigates the practical effectiveness of ventilation and dust removal purification devices.An acceptance evaluation was conducted on two mobile local ventilation dust purification systems installed in a certain locomotive depot,focusing on their sanitary and technical performance.The results indicate that both systems can achieve the required air velocity to remove the concentration of major pollutants after activation.The dust removal efficiency for welding fumes is 73.81%and 71.43%,respectively,and the purification efficiency for welding fumes exceeds 97%for both systems.Significant differences in welding fume concentration were observed before and after system activation and purification(H=0,P<0.01).The two systems have compact and suitable designs,facilitating easy mobility.The system airflow is moderate,and the distribution of operational airflow is economically rational,meeting the requirements for ventilation,dust removal,and purification.Moreover,the systems have low consumable costs,simple and convenient maintenance,these ventilation and dust purification systems are worthy of widespread promotion and use.
