The invention discloses a combined dust collector with settling cloth bags. The shell is arranged from top to bottom in turn with a clean air chamber, a dust chamber and a dust hopper. The dust chamber and a dust hopper are connected with each other. The clean air chamber and a dust removal chamber are connected with each other through a flower board. There are air holes on the flower board. A filter bag with the same number of air holes on the flower board is arranged in the dust removal chamber, and the opening end of the filter bag is sealed in the air holes on the flower board. On the top, the air outlet is arranged on the air purifying chamber, the air inlet is arranged on the dust collecting chamber, and the air inlet of the dust collecting chamber is provided with a settling dust removing device. The settling dust removing device includes settling baffle and air guide parts. The inner part of the air inlet is provided with settling baffle, and the outer part of the air inlet is provided with air guide parts. The air guide parts are a funnel-shaped cylinder body, and the area of the air inlet is smaller than that of the air outlet. Compared with the prior art, the invention has the advantages that the gravity settling chamber and the bag filter are integrated into one machine, the structure design is reasonable, the space occupied is reduced, and the service life of the bag can be prolonged.

沉降布袋组合除尘器
本专利技术涉及除尘器
,尤其涉及一种沉降布袋组合除尘器。
技术介绍
除尘器是一种把粉尘从烟气中分离出来的设备。现有一种将重力沉降室和袋式除尘器连在一起的组合式除尘器。重力沉降窒是最古老、最简易的除尘设备,主要由室体、进气口、出气口和集灰斗组成。含尘气流进入室体内,因流动截面积的扩大而使气体流速降低,较大尘粒借助自身重力作用自然沉降而被分离捕集下来。为提高重力沉降室的除尘效率,有的在室内加装一些垂直挡板,一方面为了改变气流的运动方向,由于粉尘惯性较大,不能随同气体一起改变方向,撞到挡板上,失去继续飞扬的动能,沉降到下面的灰斗中;另一方面为了延长粉尘的通行路程,使它在重力作用下逐渐沉降下来。如图所示,使气体产生一些小股涡旋,尘粒受到离心作用,与气体分开,并碰到室壁上和挡板上,使之沉降下来。(参照图1所示的沉降除尘室)组合式除尘器是在重力沉降室的净气出口与袋式除尘器的进气口之间设置连接管,含尘气体在重力沉降室初步净化后再由袋式除尘器进一步净化。由于重力沉降室和袋式除尘器是两台独立的设备,占地空间大,结构复杂。因此有必要予以改进。
