当风量较大时一般采用立式安装。立式安装有两个好处：
When the air volume is large, the vertical installation is generally adopted. Vertical installation has two advantages:
一是风量较大。立式安装可以根据风量需要灵活选择油网除尘器数量，适用于大风量系统。二是工程在使用状态下，当油网除尘器的通风阻力达到规定值时应更换油网网片。油网除尘器网片是高染毒载体，是一种二次毒源，在更换过程中可以使环境遭受再污染。立式安装除尘器有专用小室，穿戴防毒衣和面具的人进入小室把检查密闭门关上，在除尘器室内进行更换操作，对滤毒室的污染影响就小多了。
First, the air volume is large. Vertical installation can flexibly select the number of oil net dust collectors according to the air volume demand, which is suitable for large air volume system. Second, when the ventilation resistance of the oil screen dust collector reaches the specified value, the oil mesh should be replaced. The mesh of oil screen dust remover is a carrier of high contamination and a secondary source of poison, which can re pollute the environment in the process of replacement. There is a special chamber for the vertical installation of dust remover. The person wearing the gas suit and mask enters the chamber, closes the inspection airtight door, and carries out the replacement operation in the dust collector room, the pollution impact on the gas filter room is much less.
如果是管道式安装，更换除尘网的操作全部在滤毒室内进行，滤毒室的污染程度将成数量级升高。这种情况下，为了减少对滤毒室的污染，应该整体更换管式除尘器。
If it is a pipeline installation, the operation of replacing the dust removal net is all carried out in the filter room, and the pollution degree of the filter room will increase in order of magnitude. In this case, in order to reduce the pollution to the filter chamber, the tubular dust collector should be replaced as a whole.
