Industrial and mining dust explosion venting system

Abstract

The embodiment of the invention discloses an industrial and mining dust explosion venting system. The system comprises an explosion venting window, a flame blocking and extinguishing assembly and a fire extinguishing assembly, wherein an explosion venting space is formed in the explosion venting window, the flame blocking and extinguishing assembly is composed of a plurality of layers of stainless steel metal net wires with different hole diameters, the fire extinguishing assembly comprises a water storage tank, a high-pressure plunger pump, a single water pipe, a plurality of water spraying pipes and nozzles, the water storage tank is installed at the lower end of the explosion venting window, one end of the high-pressure plunger pump is connected with the water storage tank through the single water pipe, the other end of the high-pressure plunger pump is connected with the nozzle through plurality of water spraying pipes, the nozzle is fixedly arranged on the inner wall of the explosion venting window, the water spraying direction of the nozzle faces the interior of the explosion venting space, a function of completely capturing detonation flames can be realized, internal explosion energy is absorbed, the detonation temperature is effectively reduced without influencing the ambient temperature, dust generated by detonation is retained, environmental pollution caused by dust leakage is avoided, potential harmful substances are prevented from entering the environment, and personnel around the equipment, the equipment and a building are protected from being threatened by explosion pressure.

Description

technical field [0001] The invention relates to the technical field of deflagration and explosion relief, in particular to an industrial and mining dust explosion relief system. Background technique [0002] Industrial and mining enterprises emit a lot of dust pollutants in the production process, which is an important component of PM2.5 like VOCs. [0003] The sources of dust include: feeding pits, crushing and screening equipment, bulk material storage places, dust removal and ash unloading points, ore crushing, material transportation, transshipment loading and unloading, road dust and other links. The industrial dust in these links is mainly distributed in the form of fugitive emissions. Due to the lack of effective airtight measures and irregular discharge into the atmosphere, these fugitive dusts enter the atmosphere and form PM2. 5 fine particles and dust. Cause dust pollution, affecting the environment and human health. [0004] However, when a deflagration occurs ...

AI Technical Summary

Problems solved by technology

[0006] For this reason, the present invention provides an industrial and mining dust explosion venting system, through the combined use of a flame extinguishing component composed of stainless steel wire meshes with different apertures and a fire extinguishing component, to solve the problem that the fireproof and explosion venting windows in the prior art cannot The requirement to control the ambient temperature change after explosion venting, the dust generated by deflagration can easily leak into the external environment through the outlet generated by the broken fireproof explosion venting window
