Fabric Filters 布袋过滤器
Fabric filter systems, i.e., baghouses, usually consist of tubular bags made of woven synthetic fabric or fiberglass, in which the dirty gases pass through the fabric while the particles are collected on the upstream side by the filtering action of the fabric. 布袋过滤器系统，例如，布袋除尘器，通常由合成纤维或玻璃纤维制成的管状布袋组成，含尘气体通过布袋时颗粒物在纤维的过滤作用下累计在布袋上游。
The dust retained on the bags is periodically shaken off and falls into a collecting hopper for removal.定期将留在布袋里的尘土敲下并让它掉入收集漏斗以便清除。
Fabric filters usually provide very high collection efficiencies, exceeding 99.5%, at pressure drops usually ranging from 4 to 6 inches of water. 布袋过滤器通常有较高的除尘效率，超过99.5%，压力降一般在4~6英寸水柱之间。
The amount of filter area required is often based on an air-to-cloth ratio of 11.5 to 3.0 cfm of gas/ft2 of cloth. 必需的过滤面积经常基于11.5~3.0cfm/ft2 布的气布比。
The maximum operating temperature for a baghouse is 550°F using fiberglass bags. 利用玻璃纤维制成布袋除尘器最高的运行温度是550°F。
However , there may also be a minimum temperature limitation so as to maintain the g as temperature 50°F to 75°F to above the dew point. 然而，也存在最低的温度限制使得气体温度维持在高于露点温度50°F到75°F之间。
Inlet dust loadings range from 0.1 to 10.0 grains/ft3 of gas. 进口粉尘浓度在0.1~10.0grains/ft3 气体之间。
Higher concentrations in some industries are removed by a precleaning device, such as a low efficiency cyclone. 在某些工厂里高浓度的含尘气体要先用预洗涤装置分离，比如低效旋风分离器。
The baghouse has found wide application in many industries, including mining operations, food processing, grain elevators, soap and detergents, plastics manufacture and numerous other. 布袋分离器已经在很多工业领域中得到广泛的应用，包括采矿业，食品加工，谷物提升，肥皂和清洁剂，塑料制造以及众多其他工业。
Some of the industries that employ large baghouse operations are carbon black, cement, electric arc furnaces, foundry cupolas and nonferrous smelting operations.一些工业生产使用大型布袋除尘器运作，例如碳黑，水泥，电弧炉，炼铁炉和有色技术冶炼作业。
Gas cleaning by fabric filtration is suited for applications where dry particulates are handled or where water in the process gases is in the vapor stage. 布袋过滤净化气体适用于干燥颗粒物少的情况或者水在工业废气中是蒸汽状态的情况。
The basic filter collector or baghouse is capable of operating in excess of 99% efficiency, although satisfactory operation of the system is contingent upon the characteristics of the gas stream and the particulate matter being removed. 尽管系统是否良好地运转视气流的特性和颗粒物的分离量而定，但标准过滤器或者布袋除尘器能运行达到99%的效率。
Basically, the unit consists of compartments containing rows of filter bags or tubes. 运作单元主要由包含一排排的过滤袋或者滤管的过滤单元组成的。
