The invention relates to a double ash hopper inertial dust collector. The inlet adopts a nozzle acceleration to increase the inlet velocity of the dusty gas so that the velocity reaches a suitable value. After acceleration, the gas is vertically injected into the dust collector and collides with the first obstacle, the inclined baffle. After the first deceleration by collision and friction, the larger particles are restrained by the inclined baffle and then decelerated into the ash hopper 1. The smaller particles are further decelerated as the airflow turns, due to the centrifugal force into the ash hopper 2. Several cross-section abrupt changes and inclined baffles are installed in the dust collector to increase friction and reduce fluid velocity as a whole. The overall volume of the dust collector is much smaller than that of the existing inertial dust collector, and it can be more flexible to adapt to some narrow space. If used in large space, multiple duster can be connected in parallel. A pressure balance hole is arranged on the left side of the ash hopper 2 to balance the atmospheric pressure of the ash hopper 2 and the external environment and improve the fluid state in the ash hopper 2 so as to facilitate better dust removal. The inertial dust collector not only reduces the secondary dust emission, but also reduces the resistance in the process of gas flow, and also improves the dust removal efficiency to a certain extent. Moreover, the reduction of inlet air pressure directly reduces the power of the fan and achieves the effect of saving energy.
【技术实现步骤摘要】
一种双灰斗惯性除尘器
本专利技术涉及环保技术设备领域,具体为一种双灰斗惯性除尘器。
技术介绍
目前,公知的惯性除尘器有碰撞式除尘器和回流式除尘器两种,前一种除尘器主要是由一个或几个挡板阻挡气流的前进,使气流中的尘粒分离出来,虽然该形式除尘器气体流动阻力小,但是其除尘效率低。后一种除尘器的特点是把进气流用挡板分割成小股气流,为使任意一股气流都有同样的较小回转半径及较大回转角,可以采用各种挡板结构,最典型的便是百叶挡板,百叶挡板虽然能提高气流急剧转折前的速度,可以有效地提高分离效率,但速度过高会引起已捕集颗粒的二次飞扬。所以,为了克服现有除尘器的二次尘化,气体流动阻力大,除尘效率偏低的不足。因此,本专利技术提供一种惯性除尘器,对原有的装置改进优化,该惯性除尘器不仅能减少二次扬尘,还减少了气体流动过程中的阻力,也在一定程度上提高了除尘效率。而且入口风压的降低直接减少了风机的功率,达到节约能源的效果。
技术实现思路
本专利技术为一种双灰斗惯性除尘器,本专利技术要解决的问题是减少除尘过程中易出现的二次扬尘现象,减少了气体流动过程中的阻力,在一定程度上提高了除尘效率。本专利技术所采用的技术方案:提供一种双灰斗惯性除尘器,包括含尘气体入口,净化气体出口,灰斗,拐角,挡板,压力平衡孔等。采用上述结构后,通过设置多个截面突变和倾斜挡板来使含尘气体通过惯性力和离心力的作用使灰尘落入两个灰斗中,净化后气体通过净化气体出口排出。在入口处采用喷管加速来提高含尘气体的进口流速,使速度达到一个合适的数值,气体经加速后垂直射入除尘器碰撞到第一个阻碍——倾斜挡板。第一次经过碰撞摩擦减速,较大的 ...
