HKD烘干窑高温除尘器（防结露）【产品特点Characteristics】
●漏风小，清灰时对相邻小袋室没有污染
●无“二次扬尘”和“粉尘再附”现象
●结构紧凑，重量轻
●箱体结构设计,易于现场装配
●滤袋的使用寿命长等优点
●过滤工况：HKD型袋式除尘器的优点是采用具有拦阻和过滤双除尘机理组合结构。含尘烟气由灰斗上
方的进风管道进入过滤室的滤袋中，进气管道内设置有导向导流器，粗颗粒粉尘在导向导流器的阻拦及重力的作用下落入灰斗，实现了粉尘的预分离，减少了粉尘对滤袋的磨损。细粉尘随气流涌入滤袋，粉尘被滞留在滤袋上，气流则透过滤袋得到净化，净化后的气流通过引风机排入大气中。
●清灰工况：HKD烘干窑高温除尘器（防结露）的优点是用提升切换阀（柔性接触）替代其它类型烘干机袋室需要一个排风碟阀（刚性接触）和反吹风蝶阀（刚性接触）同时动作才能完成反吹清灰工作，易于实现“组合状态”清灰控制过程，清灰效果理想。
●Low volume of air leakage and no pollution to neighboring small chambers during cleaning.
●No secondary dust emission and re-adhering.
●Compact structure and light weight.
●Structure design of shell facilitates local assembly.
●Longer service life of fiter bag.
●Operation of filtration: the primary advantage of HKD bag filter for dryer is that it adopts the mechanism structures in combination of obstructing and filtration. Dust-laden smoke enters filter bags in filter chamber through the air inlet duct over the hopper. with deflector set in air duct. dust in coarse granule can fall into the hopper due to obstruction by deflector and self-gravity, which is known as pre-collecting. Therefore, abrasion of filtering bag by dust can be eased. fine dust swarms into filter bags with airflow, where dust is retained onto filter bags and air could be purified before being exhausted outside by draft fan.
●Operation of cleaning: the secondary advantage of HKD bag filter is to apply the lifting-type switch valve（flexible contact）.rather than discharge butterfly valve（rigid contact）with reverse blow butterfly valve（rigid contact）that shall be necessarily installed together for each bag chamber of other types of filters for dryer. This enables operations for removing dust to be easily controlled and highly efficient.
