一、概述
DMC式脉冲布袋除尘器是一种小型除尘器。其特点是在原机械控制脉冲式除尘器的基础上省去结构复杂，工作性能不稳定的控制器和控制阀，直接采用电磁阀控制脉冲阀工作。具有结构简单，操作稳定可靠的特点，维护保养方便快捷。
        该系列产品适用于粮食加工、建材、冶金、化工、医药制造、机械制造等行业的除尘系统中。
        二、结构
        除尘器本体由框架壳体、滤袋带笼、喷吹清灰装置、排灰装置等部分组成。壳体部分由上箱体、中箱体、灰斗、进出风口组成。喷吹清灰装置由螺旋输灰机、星型卸料阀组成。
        三、工作原理
        含尘气体由除尘器中部进风口进入箱体内， 部分较粗颗粒的粉尘由于受到重力等因素的作用，直接沉降到灰斗内，另一部分细微粉尘经滤袋过滤附着在滤袋的外表面上，洁净气体则透过滤袋，从上箱体的出风口排出。随着滤袋上粉尘的积累不断增加，除尘器滤袋粉尘层阻力上升，当除尘器达到预定的阻力范围时(1.0—1.2Kpa)，脉冲控制仪指令电磁阀启动，脉冲阀工作，并通过喷吹管向各排滤袋进行喷吹，使滤袋瞬时产生急剧膨胀，抖落滤袋外表面的粉尘，掉入下部灰斗，经由输灰装置和卸料阀排出。

        Overview
        The pulse bag-type dust collector is a small dust collector. It is characterized in that on the basis of the original mechanical control pulse dust collector, the controller and the control valve with complicated structure and unstable working performance are omitted, and the solenoid valve is directly used to control the pulse valve to work. It has the advantages of simple structure, stable and reliable operation, and convenient and quick maintenance.
This series of products are suitable for dust removal systems in grain processing, building materials, metallurgy, chemical, pharmaceutical manufacturing, machinery manufacturing and other industries.
        Structure
        The dust collector body is composed of a frame shell, a filter bag with a cage, a dust blowing and cleaning device, and a dust discharge device. The shell part is composed of an upper box, a middle box, a dust hopper, and air inlet and outlet. The dust blowing and cleaning device consists of a spiral dust conveyor and a star-shaped discharge valve.
        Working principle
        The dust-containing gas enters the box from the air inlet in the middle of the dust collector. Some of the coarse particles of dust are directly settle into the dust hopper due to gravity and other factors, and another part of the fine dust is filtered by the filter bag and attached to the outer surface of the filter bag, while clean gas passes through the filter bag and is discharged from the air outlet of the upper box. As the accumulation of dust on the filter bag continues to increase, the dust layer resistance of the dust collector filter bag increases. When the dust collector reaches the predetermined resistance range (1.0-1.2Kpa), the pulse controller commands the solenoid valve to start, then the pulse valve works, and blows through the blowpipe to each row of filter bags, causing the filter bags to instantly expand rapidly, shaking off dust on the outer surface of the filter bags, falling into the lower dust hopper, and being discharged through the dust conveying device and the discharge valve.
