Embodiment Construction

[0020] In order to better explain the present invention and facilitate understanding, the present invention will be described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0021] like figure 1 As shown, the shape of the pressure relief fire barrier layer of the flameless pressure relief device is a fan-shaped structure with a central angle greater than 90 degrees and less than 180 degrees, with a large pressure relief area and high pressure relief efficiency; the explosion vent plate 1 is installed at the entrance of the explosion vent shell 2 The inlet of the explosion venting shell 2 is connected to the pipeline; the fire retardant and pressure relief layer 4 is installed at the outlet of the explosion venting shell, and whether there is dust accumulation in the explosion venting shell can be observed through the window 3. When an explosion occurs, the explosion venting plate 1 ruptures under the action of the shock wave and pr...

Abstract

The invention relates to a flameless pressure relief device, which includes an explosion vent disc and an explosion vent shell. The outlet of the explosion vent shell is a fire retardant layer. The fire retardant layer has a multi-layered structure. The mesh number of the outer layer of the fire retardant layer is greater than The mesh number of the inner layer, the middle layer between the inner and outer layers, the middle layer is a metal mesh layer formed by laying single layers of metal mesh layer by layer. The mesh wires between the upper and lower layers of the metal mesh cross at different angles, or because Multiple metal rings are arranged in multiple layers, and the metal wires of the fire-retardant layer are crocheted. The structure of the metal ring includes a circular ring foil and a cross blade. The cross blades are connected to the inner wall of the circular foil at an oblique angle. The flameless pressure relief device involved in the present invention, in addition to inheriting the advantages of large pressure relief area and high pressure relief efficiency, can effectively capture dust and prevent the spread of flames, further ensuring human and machine safety.

Description

technical field [0001] The invention belongs to the technical field of dust collectors, in particular to a flameless pressure relief device. Background technique [0002] The flameless pressure relief device is mainly used in the wood processing industry, metal product processing industry, and other industries that generate dust. Specifically, it is mainly used on the pipelines connecting cyclone separators, dust collectors and other dust removal devices with other equipment. [0003] On July 19, 2017, a patent with application number 201720880740.8 was disclosed. This patent relates to a high flow rate anti-flame overflow flameless relief device, which includes an explosion venting plate and an explosion venting cavity. The explosion venting cavity is provided with an inlet and an outlet, and the explosion venting plate is connected to the explosion venting cavity. On the inlet, a fire-resistant layer is installed at the outlet of the explosion-venting cavity, and the fire...
