The utility model relates to a bag type dust remover, which comprises a filter chamber, an air inlet chamber and a clean air chamber. One side of the filter chamber is an air inlet and the other side is an air outlet, the lower part of the filter chamber is equipped with a ash hopper, the ash outlet of the ash hopper is equipped with a dust discharge valve, the outlet of the air inlet chamber is connected with the air inlet of the filter chamber, and the outlet of the filter chamber is connected with the air inlet of the clean air chamber The filter chamber is arranged with a dust bag, and a cloth bag installation plate is fixedly arranged between the filter chamber and the air purification chamber to separate the two. The dust bag is installed on the cloth bag installation plate, the air outlet of the dust bag is connected with the air purification chamber, and a blocking structure is arranged between the filter chamber and the air inlet chamber to block the large particles in the gas entering the filter chamber from the air inlet chamber. Through the installation of the blocking structure, the larger particles in the air are isolated in the air inlet chamber, so as to avoid the situation that the larger particles enter the filter chamber and hit the bag, so as to achieve the purpose of protecting the bag.

一种布袋除尘器
本技术涉及气体除尘
,具体涉及一种布袋除尘器。
技术介绍
在工业生产中,布袋除尘器以除尘效率高、排放浓度低、没有二次污染的特点而受到越来越广泛的应用。但在粉尘中有磨琢性颗粒的场合,使用布袋除尘器就必须在前面配备除颗粒的装置,否则,除尘器的布袋就会因为颗粒击打磨琢而容易损坏,影响使用寿命。目前,在布袋除尘器前配置的除颗粒装置一般采用以下两种:1.配置旋风除尘器作为一级除尘器,经过一级旋风除尘器除尘后的空气再进入布袋除尘器进行二级除尘。优点:旋风除尘器的特点就是能去除空气中的较大颗粒粉尘,带有细小粉尘的空气再进入布袋除尘器就不会发生颗粒击打磨损布袋的情况。缺点:a增加除尘设备投资成本。b增加了除尘系统的阻力,使得风机的风压参数必须提高,能耗增加,提高了运行成本。2.在除尘器前配置一个沉降室(也叫膨胀箱),原理是使得进入沉降室的气流流速降低,有的沉降室内还设置导风板,使气流先下后上,从而使得空气中较大的颗粒粉尘先沉降下来,不进入布袋除尘器。优点:结构简单 ...
