The utility model relates to a dust pipeline transportation technology, in particular to an anti blocking and purging technique for a dust pipeline conveying pipeline. The utility model discloses a pipe blowing device, comprising an air delivery pipeline, which is characterized in that a filter core is uniformly arranged on the inner wall of the pipeline; one end of the filter core is communicated with the carrier gas, and the other end is closed. In the technical proposal of the utility model, the high-pressure carrier gas is penetrated through each filter core, so that the dust is loosened, and the air is transported smoothly under the action of the conveying gas. Because the structure size of the filter element (mainly the diameter of the filter element) is relatively small, the structural strength of the filter element is much larger than that of the conventional sintered metal pipe breather assembly with the diameter of the pipeline. The filter core of the utility model can select different materials according to different application occasions, and the number of the filter core can be selected according to the size of the conveying pipe and the diameter of the filter element. The utility model is especially suitable for the conveying or discharging system of the high temperature and high pressure dust.

技术介绍
在煤化工等涉及粉尘输送、过滤系统的
,含尘气体通常都是通过气力输送管道进行输送或过滤排放。在生产起始阶段以及生产过程中的物料定量输送间隔时,粉料必然会由于自身的重量、颗粒的物化特性以及载气的压力而在管道内被压实而架桥,如果没有外力的松动将无法实现正常的输送。为了防止管道中粉尘架桥,实现高效输送,在粉状物料的气力输送管道中通常设置有管道吹扫器,特别是在一些容易积灰架桥的管道路段,如图1所示。该装置基于通过气体管线送来的高压气体经由载气入口10导入管道吹扫器,透过通气组件1(通常为烧结金属管)使粉料松动,实现载气对粉料的顺利输送。烧结金属管1由于其结构的特殊性,可以在使气体通过的同时,既阻挡了气体中夹带的微量水分和油分,又阻挡了粉料进入高压气体管线导致其系统瘫痪,从而确保生产的进行。现有管道吹扫器通气组件1为与排灰管径Φ相同的大口径烧结金属管,烧结金属管通常由多孔金属材料构成,并且具有较大的结构尺寸,其机械强度一般都达不到钢材等构成的输送管道的机械强度,在实际使用过程中烧 ...
