Embodiment 1

[0009] Example 1: A deflagration overpressure relief device with wave-absorbing and flame-extinguishing functions, consisting of a pipe flange 1, a bursting disc assembly 2, a relief pipe 3, an aluminum silicate wool porous material 4, and a fire-resistant corrugated plate 5 The bursting disc assembly 2 is installed at the joint of the pipe flange 1, the porous aluminum silicate cotton material 4 is attached to the inner wall of the discharge pipeline 3, and the fire-resistant corrugated plate 5 is installed at the end of the discharge pipeline 3.

[0010] refer to figure 1 , in this embodiment, when the explosion occurs in the protected container, if the pressure in the container reaches the burst pressure of the bursting disc assembly 2, the bursting disc assembly 2 will open, and the burned products, unburned medium, flame and pressure wave will all be released. to the drain line 3. In the discharge pipeline 3 , the pressure wave is absorbed by the aluminum silicate cotton...

Abstract

The invention relates to the technical field of chemical machinery and discloses a deflagration overpressure relief device with wave adsorption and flame suppression functions. The deflagration overpressure relief device is formed by pipe flanges, a rupture disk assembly, a relief pipeline, an aluminum silicate wool porous material and a fireproof corrugated plate; the rupture disk assembly is arranged at the joint of the pipe flanges; the aluminum silicate wool porous material is attached to the inner wall of the relief pipeline; and the fireproof corrugated plate is arranged at the tail end of the relief pipeline. In the emergency discharging process, a rupture disk is opened under a rated opening pressure; a discharged deflagration medium is subjected to effective wave adsorption, pressure reduction and noise reduction by the aluminum silicate wool porous material arranged on the inner wall of the pipeline so as to obviously inhibit the pressure, the flame speed and the voice strength; and then the discharged deflagration medium is subjected to fire retardance and flame suppression by the fireproof corrugated plate at the tail end. After the discharged material passes through the device, the flame and the pressure are inhibited in a combined manner and the safety of containers, equipment and people close to an outlet of the relief pipeline is effectively protected.

Description

technical field [0001] The patent of the invention belongs to the technical field of chemical machinery, and relates to a deflagration overpressure relief device with the function of absorbing waves and extinguishing flames. Background technique [0002] Many media in chemical containers and equipment are flammable. Once an explosion accident occurs, the pressure wave generated will cause damage to the container and equipment. Venting is an effective measure to weaken the explosion intensity in the container. The traditional way of relief is to use a relief device to release the combustible medium, combustion products, flames and pressure waves into the surrounding space, or lead them to other areas through the explosion venting duct, but the pressure wave and flame released are still harmful to personnel, equipment and The surrounding environment presents potential threats. How to weaken the intensity of the pressure wave released by the release and extinguish the flame ...
