摘要喷砂房除尘系统是喷砂房设计中比较重要的部分,有利于保护环境控制大气污染为国家企业的可持续发展做出重要贡献,此外还保护工人的身体健康让工人在健康的环境里工作并且提高了工作效率。一个比较完整的除尘系统应当包含以下方面:集气罩;管道;除尘设备;风机和排气管。因此,喷砂房除尘系统的设计主要包含:集气罩的形式设计和选择;除尘器的选型和设计;管道选择和阻力计算;风机的计算和选型;基建和施工安装的设计。此外还必须包括收集下来粉尘处理和除尘设备的防爆等等。52568
除尘系统的设计是关系到除尘效果的好坏,运费的高低,管理是否方便便利与否,排放是否能合格的关键环节。一般喷砂房采用旋风除尘器和布袋除尘器作为除尘设备,房内除尘系统的工作原理是:由通风机抽取喷砂房内的气体及粉尘,喷砂房外的气流经喷砂房底部的集气罩和除尘管道进入除尘系统内,经除尘系统的过滤、干净的空气排入大气,粉尘及污物则储存在粉尘筒中等待定期清理。

Abstract
Sandblasting sandblasting dust removal system is the more important part of the design, help protect the environment for the state air pollution control companies make an important contribution to sustainable development, in addition to protecting the health of workers for workers to work in a healthy environment and improve work efficiency. A more complete removal system should contain the following aspects: the hood; pipeline; dust removal equipment; blower and exhaust pipes. Therefore, sandblasting dust removal system is designed mainly includes: the hood in the form of design and selection; precipitator selection and design; pipe selection and resistance calculation; fan calculation and selection; infrastructure and construction and installation design. You must also include the collection down dust-proof treatment and dust removal equipment and so on.
Dust removal system is designed to be related to the effect of dust is good or bad, the level of freight management, convenience convenience or not, whether qualified emission key. General sandblasting used as a cyclone and baghouse dust removal equipment, room dust removal system works: the fan extraction of gases and dust blasting room, blasting outside the room air is passed through the bottom of the blasting room the hood and dust into the dust removal system piping, after the dust filtration system, clean air into the atmosphere, dust and dirt are stored in the barrel waiting for the dust cleaned regularly.
