2、，又损坏树木及农作物生长。工业通风除尘不仅可以稀释或排除生产过程中产生的毒害、爆炸气体及粉尘，给作业场所送入足够数量和质量的空气，而且可以调节作业场所的温度、湿度等气象条件，为作业人员提供舒适的作业环境。为了保证水泥厂及周围地区的空气质量，降低水泥生产过程中粉尘排放对环境的影响，国家有关产业和行业部门相继制定了环境空气质量标准GB3095-1996、 水泥厂大气污染物排放标准GB4915-2004、 水泥企业废气排放污染物监测方法等标准，以保证在水泥工业的设计、生产和监测过程中，对粉尘的排放实施有效的控制。结合我国目前的环境状况，规范中要求无论新建、改建和扩建的水泥生产项目，其热力设备烟尘排放
3、体积质量应控制在 150 mg/m3以内；属第一类生产性粉尘排放标准应控制在 100 mg/m3以内。在生产过程中粉尘的排放量与生产工艺、生产设备的造型和使用是密切相关的，水泥生产过程中粉尘的主要排放方式可分为点源排放和面源排放两种。属于点源排放的部分主要有窑尾烟囱、煤粉制备、生料磨、水泥磨均化库、水泥库等。其烟尘排放点高度通常不低于30 m，甚至超过 80 m。面源排放主要包括水泥包装及物料输送等工序产生的粉尘，其排尘点高度一般低于 15m。对粉尘排放进行工况评价时，应同时考虑粉尘内所含悬浮颗粒(1540m)及飘尘(细于 10m)的影响。本设计主要内容采用阻力平衡法，即以设计风量为基础，进行
4、环路的的阻力计算，达到支、干管道的阻力平衡。通过粉尘量的多少选定排风罩。通过通风系统 的水力计算选定通风机和除尘器。在设计过程中，引用了许多文献资料，谨向相关作者表示感谢。 昆明理工大学通风除尘课程设计3Design General Information In recent years, driven by increased industrial buildings of cement industry to flourish, while the dust generated by industrial processes can not be effectively controlle
5、d, ventilation and dust removal system is unreasonable, not only harmful to health workers, causing pneumoconiosis, under certain conditions, some dust explosion can occur, resulting in injury or death, property damage, and atmospheric pollution, affecting the survival of humanity, not only endanger
6、 the health of citizens, but also damage to trees and crops. Industrial ventilation can not only dilute or eliminate dust generated during the production of toxic, explosive gases and dust, to give as gifts to the workplace just sufficient quantity and quality of the air, but you can adjust the work
