Abstract

The invention discloses an anti-overpressure-explosion natural gas pipeline which comprises a main pipeline. The main pipeline is further provided with a plurality of branch pipelines. The inlet ends and the outlet ends of the branch pipelines are all connected to the main pipeline. The branch pipelines are in a circular arc shape. The inlet ends and the outlet ends of the branch pipes are provided with magnetic valves for controlling opening and closing of the inlet ends and the outlet ends. Pressure sensors are arranged inside the main pipeline, located on the same side of the branch pipelines and connected with the magnetic valves. The branch pipelines are located on the same plane. The gas concentration in the main pipeline is detected through the pressure sensors, when the gas concentration exceeds the warning line, the magnetic valves are opened, and distributed pressure relief is conducted on natural gas in the main pipeline through the branch pipelines arranged on the main pipeline. The branch pipelines are in the circular arc shape, and accordingly pressure can be effectively relieved. By applying the pressure sensors to detect the concentration, the detection precision is high, and the pressure relief occasion is precise. Natural gas flowing through the branch pipelines can be transmitted continuously.

Description

technical field [0001] The invention belongs to the technical field of pipelines, in particular to an overpressure explosion-proof natural pipeline. Background technique [0002] There are many dangerous factors in pipelines, among which overpressure explosion in pipelines is a common one. The overpressure explosion in the pipeline is related to the operation error or abnormal reaction of the reaction vessel. The failure of the cooling medium delivery pipeline will lead to insufficient supply of cooling medium or the middle section, which will cause the production system to overheat. The vicious cycle of overpressure eventually leads to overpressure explosion accidents in equipment and pipelines. [0003] Pipelines that continuously discharge fluids, especially process pipelines that discharge gaseous materials, will cause the boredom in the pipelines to fail to be discharged in time due to factors such as the reduction of conveying speed, resulting in overpressure explosio...
