离线清灰气箱式脉冲袋除尘器
[来源:www.zhongpinshebei.com] [作者:aywl] [日期:17-05-16]

10T中频电炉除尘器选用的是LCM型系列离线清灰气箱式脉冲袋除尘器,该除尘器是从美国富乐公司引进具有八十年代先进水平的高效率除收尘器。它综合分室反吹和喷吹脉冲清灰各类袋除尘器的优点,克服了分室反吹清灰强度不够,喷吹脉冲清灰和过滤同时进行的缺点,因而扩大了袋除尘器的应用范围,由于这种类型的除尘器的结构有其特点,所以提高了收尘效率,延长了滤袋的使用寿命。
10 t chosen is offline type LCM series intermediate frequency electric furnace filter soot cleaning air box pulse bag filter, the filter from the fule company has introduced advanced level in the eighty s high efficiency dust collector. To an integrated chamber blow and injection pulse soot cleaning all kinds of bag filter, the advantages of overcoming the chamber blow soot cleaning strength is insufficient, injection pulse ash removal and filtering simultaneously, thus expanding the application range of bag filter, because the structure has the characteristics of this type of filter, so improving the dust collecting efficiency, prolong the service life of filter bag.

 
本系列产品广泛用于冶金、化工、机械、水泥和民用锅炉等废气的收尘系统。除尘器由壳体、灰斗、排灰装置、支架和脉冲清灰系统等部分所组成。当含尘气体从进风口进入除尘器后,首先碰到进出风口中间的斜隔板,气流便转向流入灰斗,同时气流速度变慢,由于惯性作用,使气体中粗颗粒粉尘直接落入灰斗,起到预收尘的作用。进入灰斗的气流随后折而向上通过内部装有金属骨架的滤袋,粉尘被捕集在滤袋的外表面,净化后的气体进入滤袋上部的清洁室,汇集到出风管排出。LCM型除尘器的进风口设在灰斗上。气流进入灰斗后首先碰上进风管端部的挡板,其作用与上述原理相同。壳体用隔板分成若干个独立的收尘室,按照给定的时间间隔对每个收尘室轮流进行清灰。每个收尘室装有一个提升阀,清灰时提升阀关闭,切断通过该收尘室的过滤气流,随即脉冲阀开启,向滤袋内喷入高压空气,以清除滤袋外表面上的粉尘。各收尘室的脉冲喷冲吹宽度和清灰周期,由专用的清灰程序控制器自动连续进行。
This series is widely used in the dust collection system of metallurgy, chemical, mechanical, cement and civil boiler. The dust collector consists of the shell, the dust bucket, the ash device, the scaffold and the pulsed grey system. After the dust from the air inlet gas into the dust catcher, first met through the inclined plate, the middle of the outlet air turned into the ash bucket, airflow speed slower at the same time, due to inertia effect, coarse particles of dust in the gas directly into the hopper, have the effect of dust in advance. The airflow into the ash hopper then fold and upward through internal equipped with metal frame filter bag, dust was set on the outer surface of the filter bag, after purification, the gas into the upper part of the filter bag cleaning chamber, packed into the duct drainage. The inlet of the LCM filter is in the dust bowl. The air flow enters the dust bowl and first meets the fender of the wind tube, which is the same as the above principle. The shell is divided into several separate dust Chambers, which take turns in each collection room at a given interval. Each dust collecting chamber is equipped with a lift valve, lift valve closed when ash removal, cut through the dust collecting chamber of filtering flow, and pulse valve open, the air injection pressure inside the filter pocket, to remove dust on the surface of the filter bag appearance. The pulse blast width and gray cycle of each dust chamber are automatically carried out automatically by the special grey program controller.
