Explosion-proof exterior wall with pressure relief function

Abstract

The invention discloses an explosion-proof exterior wall with a pressure relief function. The explosion-proof exterior wall comprises a ventilating pipe (1) positioned in a explosion-proof wall body (a). The ventilating pipe (1) is internally provided with a pressure relief pipe (2). A cavity used for high pressure airflow to pass is arranged at the position between outer side surface of the pressure relief pipe (2) and the inner wall of the ventilating pipe (1). The end of the pressure relief pipe (2) is vertically welded to a baffle (3). The end at the opposite end of the pressure relief pipe (2) and the baffle (3) is fixedly welded to a positioning plate (4). The whole baffle (3) is of a plate structure with a pressure relief hole (b) formed in the middle portion. The pressure relief hole (b) is internally provided with a pressure relief plate (5) in a clearance fitting mode. The explosion-proof exterior wall is simple in structure and convenient to use; the sealing effect is guaranteed and the effects of explosion-proof and pressure relief of the whole wall body is effectively improved.

Description

technical field [0001] The invention relates to the technical field related to explosion-proof buildings, in particular to an explosion-proof outer wall with a pressure relief function. Background technique [0002] Building explosion-proof is an explosion-proof design for buildings with explosion hazards such as factories and warehouses. At present, buildings with explosion hazards should be single-story. A large amount of gas and heat are released, which creates a high pressure in the room. In order to prevent the load-bearing components of the building from being damaged due to the strong explosive force, the usual method is to design the top of the explosion-proof wall as a weak pressure relief structure. The current common way to design the pressure relief structure is to install the corresponding skylight, but when the skylight explodes, a large amount of glass shards will splash and cause secondary damage to personnel. In order to solve this problem, a kind of The ex...

[0002] Building explosion-proof is an explosion-proof design for buildings with explosion hazards such as factories and warehouses. At present, buildings with explosion hazards should be single-story. A large amount of gas and heat are released, which creates a high pressure in the room. In order to prevent the load-bearing components of the building from being damaged due to the strong explosive force, the usual method is to design the top of the explosion-proof wall as a weak pressure relief structure. The current common way to design the pressure relief structure is to install the corresponding skylight, but when the skylight explodes, a large amount of glass shards will splash and cause secondary damage to personnel. In order to solve this problem, a kind of The explosion-proof wall using louvers as the pressure relief structure, although the pressure relief structure of the explosion-proof wall can effectively avoid the secondary damage caused by the splashing glass fragments, but the air waves generated at the moment of the explosion spread in a straight line. The blades of the louvers are designed to be inclined, which is not conducive to the rapid diffusion of high-pressure air waves. At the same time, the overall sealing effect of the louvers is poor. For some dangerous goods that are prone to moisture and explosion, the storage environment is very dangerous.
