Abstract

The invention discloses an explosion suppression and explosion venting double-protection device for a communication container. The explosion suppression and explosion venting double-protection device comprises explosion venting devices arranged on a first container and a second container of the communication container respectively, and wire screens embedded in connection pipelines of the first container and the second container as explosion suppression devices, wherein each explosion venting device comprises an explosion venting pipeline; the bottom end of each explosion venting pipeline is fixed at the container top of the communication container to communicate the pipeline with the container; a flange and an open flange cover are arranged at the top end of each explosion venting pipeline; and a rupture disk is installed at the junction of each flange and the corresponding flange cover. The invention further discloses a communication container provided with the explosion suppression and explosion venting double-protection device. The explosion suppression and explosion venting double-protection device disclosed by the invention is reasonable in structure, convenient to operate, high in safety, capable of effectively reducing a pressure generated by explosion, and capable of properly reducing the thicknesses of fire-retardant screens, increasing porosity, reducing generation of static electricity, and decreasing an accident rate. The communication container achieves a higher safety coefficient under the double action of explosion suppression of the fire-retardant screens and explosion venting of the explosion venting devices.

Description

technical field [0001] The invention relates to a dual protection device for explosion suppression and explosion venting of a connected container. Through the double protection functions of explosion suppression and explosion venting, the protection device protects the connected container when the gas explodes in the industrial process, improves the safety performance of the connected container, and achieves The best security benefits of containers. Background technique [0002] In the process of chemical and petrochemical production, pipeline transportation of flammable and explosive gases is widely used because of its low cost and simple process. Due to the confinement, gas explosions can generate high pressures and pressure rise rates, causing property damage and personal injury. However, in the connected container device where the container is connected to the pipeline, due to the pressure accumulation effect and the secondary explosion, the consequences of the gas expl...
