电袋除尘器安装工艺

Installation Process of Electric Bag Dust Collector

电袋除尘器是将电除尘器技术和布袋除尘技术相结合的一种复合除尘技术,烟气从前烟道加入电除尘一电电场,在高电压作用下带电粉尘沉积通过电除尘振打落入灰斗。经过初步除尘的烟气经多孔型板进入袋除尘器,经过布袋除尘过滤后粉尘吸附在滤袋外表面,经过除尘的烟气流经电除尘后烟道通过烟囱排放。吸附在滤袋表面的粉尘达到一定厚度后,通过压缩空气吹扫达到清灰目的。本文通过对榆林化学动力站3#除尘器安装采用的塔吊布置形式、电袋除尘器安装工序、组合形式和部分部件起吊方法等,确定电袋除尘器安装需选用的优化方案,缩短电袋除尘器安装工期。

The electric bag dust collector is a composite dust removal technology that combines the electric dust collector technology and the bag dust removal technology.The flue gas is added to an electric dust removal electric field from the front flue,and the charged dust deposits under the action of high voltage through the electric dust removal vibrating Fall into the ash bucket.The flue gas after preliminary dust removal enters the bag filter through the porous plate,and the dust is adsorbed on the outer surface of the filter bag after the bag dust removal and filtration,and the dust-removed flue gas is discharged through the chimney through the flue after the electric dust removal.After the dust adsorbed on the surface of the filter bag reaches a certain thickness,it is purged by compressed air to achieve the purpose of dust removal.In this paper,the layout of the tower crane,the installation process of the electric bag filter,the combination form and the lifting method of some components used in the installation of the 3#dust collector of the Yulin Chemical Power Station are determined to determine the optimal plan for the installation of the electric bag filter to shorten the electric bag dust removal.Installation period.
