The design of bag dust removal equipment is led by fixed products. However, in order to make the dust removal equipment more suitable for use, some large bag dust removal equipment design specifications must be customized. This design can achieve the best dust removal filtration. The effect, now, the equipment of many dust collector manufacturers are tailored according to customer needs, and new products are constantly being designed. Therefore, it is necessary to pay attention to the design specifications of bag dust collectors. What are the factors that affect the dust removal of bag dust removal equipment?
： 运行状态的影响 因素 。 1 : Influencing factors of operating status .
Classification efficiency of the same filter cloth under different loading conditions. Obviously, the dust removal efficiency of the clean filter cloth is the lowest, the dust removal efficiency of the filter cloth after dust accumulation is the highest, and the dust removal efficiency of the filter cloth is reduced after the dust cleaning. It can be seen that the main function of the bag type dust collector is the dust layer on the surface of the filter cloth, and the filter material only plays the role of forming the primary layer of dust and supporting the skeleton. Therefore, when cleaning, the initial dust layer should be kept to avoid the reduction of dust removal efficiency.
： 粉尘粒径的影响 因素 。 2 : Influencing factors of dust particle size .
0.2 ～ 0.4μm 的尘粒，三种状态下的除尘效率均最低，因为这一范围的尘粒处在拦截 For 0.2 to 0.4 μm dust particles, the dust removal efficiency is the lowest in the three states, because the dust particles in this range are intercepted
0.2 ～ 0.4μm 的尘粒是最难捕集的。 The lower limit of the action and the upper limit of the diffusion action, therefore, dust particles of 0.2 to 0.4 μm are the most difficult to capture. However, the post-treatment and coating of the filter cloth have greatly improved the efficiency of capturing fine particles.
： 滤布结构及粉尘层厚度的影响 因素 。 3 : Influencing factors of filter cloth structure and dust layer thickness .
的粉尘厚度用粉尘负荷 Q 表示，它表示 1m2 滤料上沉积的粉尘质量，不同滤布结构的除尘效率与粉尘负荷的关系如图 2-42 所示。 The thickness of the dust deposited on the surface of the filter cloth is represented by the dust load Q , which represents the quality of the dust deposited on the 1m2 filter material. The relationship between the dust removal efficiency and dust load of different filter cloth structures is shown in Figure 2-42 . Obviously, the dust removal efficiency increases as the dust load increases. As far as filter cloth is concerned, fleece cloth and needle felt have higher dust removal efficiency than plain cloth, and fleece length is higher than short fleece.
是衡量 布袋除尘设备 性能最基本的参数，它表示除尘器处理气流中粉尘的能力，它与滤料运行状态有关，并受粉尘性质、滤料种类、阻力、粉尘层厚度、过滤风速及清灰方式等诸多因素影响。 Bag dust removal equipment is the most basic parameter for measuring the performance of bag dust removal equipment . It indicates the ability of the dust collector to handle dust in the air stream. It is related to the operating status of the filter material and is affected by the nature of the dust, the type of filter material, resistance, thickness of the dust layer, and filtration Many factors such as wind speed and dust removal methods.
