The invention discloses an electric dust collector plate row heat deformation device, comprising a plurality of steel girder, a seat plate, card, card, arm bolts, nuts and gaskets, each pair of beams distributed in ESP each field of front and rear, and across the field on both sides of the shell wall. Each steel beam is provided with a pair of steel beam seats which are welded by the steel beam seat and the shell wall plate, and the steel beam itself can rotate in the steel beam seat. The polar plate is symmetrically fixed by the bolt, the nut and the washer in the electric field, the two sides of the polar plate row are on the outermost wind groove, each row is symmetrically equipped with a pair of polar plate cards. Each plate card is connected with the adjacent near steel beam in a \Ding\ shape, and is welded by both ends of the clamping arm. The utility model has the advantages of simple structure, practicability, reliability and low cost. The utility model can be used not only for the design of the heat shield deformation of the polar plate of the electrostatic precipitator in the new design, but also for the online maintenance of the heat distortion of the polar plate of the electric dust collector which has been put into operation. Prevent the plate from being bent two times, reduce the production, maintenance and replacement of the polar plate, and save the maintenance time and cost.

,具体属于一种电除尘器极板排防热变形装置。
技术介绍
极板排是电除尘器最重要的组成部分之一,其工作性能直接影响电除尘器的除尘效果。极板排是由若干块单元极板经串联对接成一排组成。极板排由于单元极板本身外形细长和厚度偏薄的特性而极易变形,特别遇高温,变形更加明显。如果不加以防范,极板排的严重变形,将导致极板排排间距(又称烟气通道)变窄甚至相碰,进而发生两电极电压严重下降,甚至短路。此时,电除尘器效率显著降低,出口排放无法达标。一般在正常烟气温度的情况下,电除尘器极板排变形均在允许范围之内,极板排排间距不变,因而不会对除尘器收尘效率产生影响。但是,当前随着工业生产中新技术和新工艺的大量应用,烟气温度时常会出现波动,甚至会发生显著的提高,因而给极板排带来严重的热变形问题,尤其对于已经投产的电除尘器,极板排热变形问题显得更加突出。因为其中还要同时解决在线维修的问题。否则就要被迫停产,以便维修或更换变形的极板排。
