为了适应造船工业的日益发展,各船厂在拚板焊接与构架装焊作业中,已越来越多地采用自动埋弧焊技术。但是,在施焊过程中,对复盖在焊缝上的剩余剂焊,目前,大都采用手工清除和回收。为了解决这个问题,有些船厂采用送入式或吸入式的焊剂回收装置回收剩余焊剂。采用送入式装置时,焊剂和压缩空气混合,焊剂容易被压缩空气中的油污和水份污染,影响焊接质量。不论采用送入式装置还是一般吸入式装置,在排出废气中,都含有大量的细小焊剂和粉尘, In order to adapt to the growing development of the shipbuilding industry, all shipyards have increasingly adopted the automatic submerged arc welding technology in their assembly welding and frame assembly welding operations. However, in the welding process, the rest of the welding covered on the weld, at present, most of the manual removal and recovery. In order to solve this problem, some shipyards use a feed-in or suction-type flux recovery device to recover the residual flux. The use of feed-in device, the flux and compressed air mixture, the flux easily be compressed air pollution and water pollution, affecting the quality of welding. Regardless of the use of feed-in devices or general inhalation device, in the exhaust emissions, contains a lot of fine flux and dust,
