HG5丝网除沫器型式、结构与安装说明
一、 丝网除沫器型式
丝网除沫器型式有:升气管型、缩径型、全径型
1、升气管型(HG5-1404-81)
丝网除沫器的网块安装在设备顶部升气管下端。
2、 缩径型(HG5-1405-81)
当设计的丝网除沫器的网块直径小于设备筒体直径时,需要另外加一短节安装网块。
3、 全径型(HG6-1405-81)
设计的丝网除沫器的网块直径等于设备筒体直径时,网块直接安装在筒体内。
二、 网块结构
丝网除沫器的网块结构有两种:盘形网块和条形网块。
1、盘形网块
用丝网卷制成所需直径的网块,网块的厚度等于丝网的宽度规格,这种网块充分地利用了丝网材料,没有边角预料损耗。但卷制时要求各圈必须卷得密疏一致,不然易产生短路,影响除沫效果。盘形网块不宜用手工制作,应用机械卷制,以保证卷制质量。盘形网块仅适用于较小直径的丝网除沫器,本标准产品用于Dg300~600㎜
2、条形网块
条形网块是目前使用最普遍的结构。它是用丝网一层层地平铺,铺至规定层数,再在网层上面与下面各放一块格栅,然后将网层压至所需厚度尺寸,用定矩杆与钩使其成为一整块。条形网块的形状与尺寸,随公称直径与分块数量而变化。
3.、网块安装
网块安装时,有从上往下装与由下往上装两种情况,因此,丝网除沫器有上装式与下装式两种结构。当人孔位置开设在丝网除沫器的上面,或无人孔而有设备法兰时,选用上装式丝网除沫器;人孔位置开设在丝网除沫器的下面,选用下装式丝网除沫器。
