有些乡镇企业在生产过程中产生大量有害粉尘。为控制职业危害,需要采取综合防尘措施。其中通风除尘是一项重要的技术措施。一套完整的通风除尘系统由吸尘罩、风道、风机和除尘器组成。按照不同的物理作用原理,除尘方法又可分为下列数种:一、利用重力和惯力作用除尘。其设备为重力沉降室。使含尘空气通过一小室,由于小室断面比风道大得多,气流速度降低,在重力作用下,粉尘
Some township and village enterprises produce a large amount of harmful dust in the production process. To control occupational hazards, we need to take comprehensive dust control measures. Ventilation dust removal is an important technical measure. A complete set of ventilation and dust removal system consists of dust cover, air duct, fan and dust collector. According to different physical principle, dust removal methods can be divided into the following categories: First, the use of gravity and inertia role of dust removal. Its equipment is gravity settling chamber. So that dust-laden air through a small room, because the small section of the chamber is much larger than the air duct, the air flow rate decreases, under the action of gravity, dust
