Tubular filter device, filter element and use of such tubular filter device

A tubular filter device (1000) comprising a tubular filter element (100) and a tubular air pulse distributor (300) is provided. The filter element comprises a tubular pleated filter media (106) having an initial circular cross-section, and a cage structure (120) arranged along an outer envelope surface thereof to support the pleated filter media. The outer envelope surface of the cage-like structure defines a first set and a second set of two opposing wall portions (123, 124). The inner wall (107) of the pleated filter media is elastically deformed to conform to the outer envelope surface of the cage structure (120) with the pleated filter media arranged to surround the outer envelope surface of the cage structure (120). The tubular air pulse distributor includes a locking member (303) configured to allow the tubular air pulse distributor to lockingly engage the tubular filter element. 提供了一种包括管状过滤元件(100)和管状空气脉冲分布器(300)的管状过滤装置(1000)。该过滤元件包括具有初始圆形截面的管状褶状过滤介质(106)、和笼状结构(120)，该笼状结构沿着其外包络表面被布置为支撑该褶状过滤介质。该笼状结构的外包络表
