Pressure relief device for explosion-proof workshop

Abstract

The invention belongs to the technical field of workshop pressure relief, and particularly relates to a pressure relief device for an explosion-proof workshop. The pressure relief device comprises a plurality of sets of pressure relief modules installed on a roof. A pressure relief unit designed by the invention is composed of four triangular baffles as main components, when an explosion occurs inthe workshop, the four triangular baffles can be quickly impacted and opened to the outer side, compared with the traditional situation that a pressure value in the workshop needs to meet the pressure when an explosion relief bolt falls off, and then a window sash can be automatically opened to discharge the pressure outwards, the pressure required for opening the four triangular baffles designedby the invention is relatively small, and the damage to the workshop caused by the pressure change before pressure relief in the workshop is reduced to a certain extent.

Description

[0001] Technical field [0002] The invention belongs to the technical field of pressure relief for factory buildings, and in particular relates to pressure relief equipment for explosion-proof factory buildings. Background technique [0003] Explosion-proof factory building refers to the factory building with explosion hazard or the factory building with explosion hazard parts in the factory building; the explosion-proof factory building should be equipped with pressure relief facilities. [0004] The current explosion-proof plant has the following problems: [0005] First, the setting of pressure relief equipment such as pressure relief windows and pressure relief roofs has a relatively high damage limit in the event of an explosion, which still causes certain damage to the factory building; such as explosion relief windows, which use steel window frames and are equipped with special Hinges, pressure relief devices and other hardware accessories; when the air pressure diffe...

AI Technical Summary

Problems solved by technology

[0005] First, the setting of pressure relief equipment such as pressure relief windows and pressure relief roofs has a relatively high damage limit in the event of an explosion, which still causes certain damage to the factory building; such as explosion relief windows, which use steel window frames and are equipped with special Hinges, pressure relief devices and other hardware accessories; when the air pressure difference inside and outside the building reaches a certain value, the explosion relief bolts of the pressure relief window will automatically fall off, the window sash will automatically open, and the pressure will be discharged outward; however, the explosion relief bolts need a certain pressure to fall off. Before the pressure value is reached, the factory building needs to bear the pressure change in the factory building before the pressure relief window is opened, causing certain damage to the factory building

[0006] Second, the explosion venting equipment on the wall is relatively unsafe compared with the explosion venting equipment on the roof. The roof is on the factory building, and it will generally not cause secondary harm to people during pressure relief, but the pressure relief equipment on the roof must consider strong wind and The impact of rainwater will not be blown away in strong winds, and will not leak when it rains. The existing equipment is mainly designed with pressure relief in mind. It is not considered in the design of strong winds and rain leakage, but only during installation. Through reliable installation and sealing, the effects of wind resistance and rain prevention can be obtained. After a long time of use, due to the aging of the gasket and the vibration caused by the wind, the fixation will not be firm and the rain will leak.
