焊接烟尘和烟气含有大量有毒有害物质,其主要成份为铁和锰等金属氧化物,其粒度为0.10μm～1.25μm,被称之为呼吸性粉尘,对人体健康危害极大。因此,改善工人作业环境,保护职工身体健康,防止烟尘排放造成对大气的污染,使治理焊接烟尘成为必然。本文介绍了采用吹吸式均匀流排烟方式及侧吸方式的除尘系统,将有毒有害烟尘控制在工人的呼吸带以下,经布袋除尘器净化后排放。
Welding fumes and fumes contain a large number of toxic and hazardous substances, the main component of iron and manganese and other metal oxides, the particle size of 0.10μm ~ 1.25μm, known as respiratory dust, great harm to human health. Therefore, to improve the working environment of workers, protect the health of staff and workers, prevent the pollution caused by smoke and dust emissions, and make the management of welding dust become inevitable. This paper introduces a dust removal system that adopts the method of uniform suction and suction and the side suction method to control poisonous and harmful fumes below the worker’s breathing zone and purify them by the bag filter.
