Description

工业废气净化处理远程监控系统 技术领域
本发明属于工业废气处理技术领域，特别是涉及一种工业废气净化处理远程监控系统。
背景技术
废气排放是指烟囱或排气管洞口排出的废气中污染物质。是大气环境的严重的污染源。工业企业燃烧和生产工艺过程中排放的各种废气。涂料中的有机挥发性物质是造成大气污染的主要原因，而涂装过程中的污染要比涂料制造厂严重许多。在涂料生产中，放入大气中的溶剂量不超过涂料制造时溶剂用量的2％，其中球磨法生产过程中的溶剂挥发不到0.25％。然而，在涂料涂装过程中，随着涂料的种类和涂装方法的不同，损失从20％到80％不等。例如，在空气喷涂作业中，溶剂型涂料的50％～70％在涂装过程中以漆雾飞散掉，全部的有机溶剂挥发释放到大气中。涂装中排放有害废气主要集中在喷漆生产线上，喷漆室、晾干室、烘干室是废气的主要发生源。
专利号CN 104898719 B公开了“污染源VOC浓度及排放总量实时监控系统”，通过废气参数测量单元检测出废气的温度、压力、湿度和流速等参数，通过VOC检测单元检测VOC浓度，进而对VOC的排放总量进行实时监控。但是这种方式仅限于检测出废气的VOC浓度，当处理后废气中的VOC含量还是偏高时，无法进行再处理而是直接排放空气中，影响空气质量。
