The utility model relates to a grille plate for dry cleaning of blast furnace gas, which is characterized in that the grille plate is centered on the center of any filter bag hole, and six filter bag holes are arranged equidistantly around the grille plate to form a regular hexagonal arrangement. By analogy, the center of all filter bag holes is positioned on the whole grille plate, so that the center distance of the filter bag holes is formed by the equilateral triangular edge of the adjacent filter bag holes. The net distance between the outer edge of the filter bag hole at the outermost edge of the grille and the inner wall of the dust removal box is more than 200 mm. The utility model has the advantages that the sixty degree plum blossom arrangement is formed between the filter holes on the lattice plate made by the method of the utility model, and the layout method of the lattice plate opening is optimized, which can increase the number of filter bag holes by more than 10% compared with the conventional rectangular array structure arrangement method. Without increasing the number of dedusting boxes, the filter area is increased by more than 10%, the dedusting efficiency and effect of the whole dry bag dedusting system of blast furnace gas are improved, and the construction investment cost is reduced.

高炉煤气干法除尘箱体花格板
本技术涉及钢铁冶金高炉煤气除尘
,特别涉及一种高炉煤气干法除尘箱体花格板开孔方法及花格板。
技术介绍
现有的高炉煤气干法除尘箱体中花格板上滤袋孔的布置多采用如图1所示的矩形阵列结构布置,这种矩形阵列结构的开孔方法存在以下不足:1、滤袋孔布置的数量较少,单个除尘箱体的过滤面积较小,除尘箱体的除尘效果和除尘效率不佳;2、增加了除尘箱体的数量,增大了整个高炉煤气干法袋式除尘系统的基建投资及维护工作。
技术实现思路
本技术的目的就是提供一种在不增加花格板面积且满足最小孔间距的条件下增加滤袋孔布置的数量,加大单个除尘箱体的过滤面积,减少高炉煤气干法袋式除尘系统除尘箱体的数量,节约高炉煤气干法除尘建设投资的高炉煤气干法除尘箱体花格板开孔方法及花格板。本技术的解决方案是这样的:一种高炉煤气干法除尘箱体花格板,在花格板上开有多个滤袋孔,多个滤袋孔为多排横向间隔排列,相邻横向间隔的滤袋排在纵向相互等距错开,形成任一个滤袋孔同时与六个滤袋孔相邻的正六边形排列结构;处于花格板最外侧滤袋孔外缘离除尘箱体内壁净距大于200mm。本技术的优点是花格板上的滤孔之间形成 ...
