                  实验室通风系统工程设计原则


                  是整个实验室设计和建设过程中,规模最大、影响最广泛的系统之一。通风系统的完善与否,直接对实验室环境、实验人员的身体健康、实验设备的运行维护等方面产生重要影响。实验室过度负压,通风柜气体泄漏,实验室噪音等问题,一直是困扰实验室工作人员的难题。这些问题给长期在实验室中工作的人员,甚至工作在实验室周围的管理和后勤人员,造成了身体和心理?#31995;难?#37325;伤害。一个科学、合理的通风系统要求通风效果好、噪音低、操作简便、节约能源,甚至要求室内压差和温湿度都能保持人体的舒适性。


                  1、根据大楼的结构特点,就近开设风井,划分排风和补风系统,管道系统做?#20581;?#30701;、?#20581;?#39034;、直?#20445;?#20943;小系统阻力,降低系统噪声; 

                  2、排风和补风系统达到风?#31185;?#34913;,保持室内-5Pa—-10Pa的负压,防止有害气体的散溢,保证实验人员的身心健康; 

                  3、夏天补冷风、冬天补暖风,保证室内温湿度的舒适性; 

                  4、采用智能变频控制系统,达到操作方便、节能降噪的?#24247;模?nbsp;

                  5、综合考虑各项因素,采用投资少、运行稳定、运行费用低、运行效果好的成熟工艺; 

                  6、所选择的工艺必须满足现场条件,平面布置简洁、紧凑、少占地,并方便生产操作和维护维修; 

                  7、非标设备应符合国家或行业相关规范,并保证性能稳定、外表美观; 

                  8、在设计中充分考虑噪声、臭味等,防止二次污染的产生,不给周围环境造成新的污染; 

                  9、处理设施具备冲击负荷能力,确保废气达标排放。
