焊接车间在大量的焊接工作中,会产生大量的焊接烟尘,对人体造成危害,如造成职业病。焊接过程所产生的金属和非金属微粒会刺激操作者的呼吸道,造成其呼吸困难。同时,它对车间工作环境也有很大的影响。由此可见焊接车间通风除尘是焊接工人最重要的防护措施之一。因此,有必要对焊接车间进行通风,去除或稀释工作环境中的有害物质,从而建立良好的焊接环境。常见的控制车间内焊接烟尘的污染方式有多种,常用到的有对车间基本除尘布局的优化设计、通过植物的除尘系统、除尘集气罩的设计、滤波器的选择、通风管网的设置、风机选择等。本文针对工作台的具体尺寸和装置的整体尺寸,简述了通过对集气罩和通风道的布置的设计过程,以使除尘系统配置合理化。 Welding workshop in a large number of welding work, will produce a large number of welding fumes, causing harm to humans, such as causing occupational disease. Metallic and non-metallic particles produced during the welding process irritate the operator’s respiratory tract, causing breathing difficulties. At the same time, it has a great impact on the workshop environment. This shows that the welding workshop ventilation and dust removal is one of the most important protective measures for welding workers. Therefore, it is necessary to ventilate the welding workshop, remove or dilute the harmful substances in the working environment, so as to establish a good welding environment. Common control workshop welding dust pollution in a variety of ways, commonly used to have the basic layout of the workshop layout of the optimal design, through the plant’s dust removal system, dust collector hood design, filter selection, ventilation network settings , Fan selection and so on. In this paper, according to the specific size of the workbench and the overall size of the device, the design process of the layout of the collector hood and the ventilation duct is briefly described so as to rationalize the configuration of the dust removal system.
