Problems solved by technology

This flameless relief device has the following disadvantages: 1. The flow rate generally can only reach about 30%, and the diameter of the flameless relief device needs to be increased by more than 3 times without changing the effective flow area of ​​the pipeline; 2. Because the corrugated plate is pressed by steel plate, the weight is relatively heavy, which increases the overall weight of the flameless relief device. When it is installed on the pipeline, it is necessary to use large-diameter bolts to withstand the shear stress; 3. Difficult to maintain, It is necessary to disassemble the flanges on both sides to remove the flameless relief device, and then perform maintenance

Abstract

The invention relates to a dust flameless releasing device. The dust flameless releasing device comprises an explosion venting plate and an explosion venting cavity. The explosion venting cavity is provided with an inlet and an outlet. The explosion venting plate is connected to the inlet of the explosion venting cavity. A flame retarding layer is arranged at the outlet position of the explosion venting cavity, and a filter net made of stainless steel materials is adopted in the flame retarding layer. A fan shape can be seen from the side face of the outlet of the explosion venting cavity. The stainless steel filter net is adopted as a flame retarding material of the flame retarding layer, the circulation rate is increased, the weight of the flame retarding layer is reduced, and cost is reduced. The flame retarding layer is designed into the fan-shaped structure, the releasing area is increased, and mounting and dismounting are convenient.

Description

technical field [0001] The invention relates to a flameless pressure relief module applied to pipelines, in particular to a dust flameless relief device. Background technique [0002] Flameless relief devices are mainly used in grain, metallurgy, chemical industry, electric power, pharmaceutical, mechanical processing and other industries, and are specifically used in pipelines connected to cyclone separators, dust collectors, dust collectors, cartridge filters, pneumatic conveying and other equipment . [0003] In the prior art, the flameless relief device is connected to the pipeline through the flanges on both sides, and the internal fire extinguishing module is mainly composed of corrugated plates pressed by steel plates. This flameless relief device has the following disadvantages: 1. the flow rate generally can only reach about 30%, and the diameter of the flameless relief device needs to be increased by more than 3 times without changing the effective flow area of ​​...
