石化企业VOCs的收集和输送方法以及集中处理系统
摘要：
本发明属于工业尾气治理技术领域，涉及一种石化企业VOCs的收集和输送方法以及集中处理系统。本发明提供的石化企业VOCs的收集和输送方法，将VOCs浓度≤25000mg/m3的气体通过收集管线输送至混合器中；将VOCs浓度＞25000mg/m3，且VOCs浓度≤50000mg/m3的气体经过稀释管线稀释后输送至混合器中；将VOCs浓度＞50000mg/m3的气体经过预处理装置处理后输送至混合器中；VOCs排放点的输出端通过所述收集管线与所述混合器的输入端连通，所述的收集管线上设置VOCs浓度监测仪和阻火器。本发明能够确保石化企业在收集、输送以及处理VOCs的过程中的安全性，有利于统一集中处理。
摘要（英）：

The invention belongs to the technical field of industrial exhaust gas treatment and relates to a method for collecting and conveying VOCs of petrochemical enterprises and a centralized processing system. The method for collecting and conveying VOCs of petrochemical enterprises, provided by the invention, comprises the following steps: conveying a gas in VOCs concentration of less than or equal to 25000mg/m3 into a mixer through a collecting pipeline; diluting the gas with the VOCs concentration of more than 25000mg/m3 but less than or equal to 50000mg/m3 by a diluting pipeline and then conveying into the mixer; adopting a pre-treating device for treating the gas with the VOCs concentration of more than 50000mg/m3 and then conveying into the mixer; connecting an output end of a VOCs emission point with an input end of the mixer through the collecting pipeline and arranging a VOCs concentration monitor and a flame arrester on the collecting pipeline. The method provided by the invention is capable of guaranteeing the safety of the petrochemical enterprises in the processes of collecting, conveying and treating VOCs and is beneficial to the uniform centralized treatment.
