Return outlet hydrogen sulfide and flow dynamic monitoring device

The utility model discloses a return outlet hydrogen sulfide and flow dynamic monitoring device which comprises a wellhead horn pipe, the side wall of the wellhead horn pipe is communicated with a pipe A, the end, away from the wellhead horn pipe, of the pipe A is communicated with a flow monitoring groove, the end, away from the pipe A, of the flow monitoring groove is communicated with a pipe B, and a sensor assembly is arranged on the flow monitoring groove. The sensor assembly is sequentially connected with a data processing unit, a computer and an audible and visual alarm. The device provided by the utility model solves the problems of large flow measurement error, reaction lag and no hydrogen sulfide monitoring at a return outlet in the prior art. 本实用新型公开了一种返出口硫化氢及流量动态监测装置，包括井口喇叭管，井口喇叭管的侧壁连通有管A，所述管A远离井口喇叭管的一端连通有流量监测槽，流量监测槽远离管A的一端连通有管B，流量监测槽上设置有传感器组件，传感器组件依次连接有数据处理单元、计算机、声光报警器。本实用新型装置解决了现有技术中流量测量误差大及反应滞后且在返出口无硫化氢监测的问题。
