Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of explosion test systems, and in particular relates to an explosion relief test system and method for simulating accidental explosion of an industrial plant structure. Background Art
[0002] When constructing industrial plant structures with potential explosion risks, their explosion-proof capabilities should be taken into consideration. Currently, the most widely used and effective means of explosion-proofing is explosion-proofing design, which is already covered in the Code for Fire Protection Design of Buildings.
[0003] (GB50016-2018), "Explosion-resistant and explosion-proof doors and windows, roofs and wall building structures" (14J938) and other specifications have made relevant provisions; however, due to the many characteristics of explosion loads such as short duration, strong load, easy to occur suddenly, difficult to warn, and large damage, the explosion-proof structure exhibits very complex dynamic behavior when subjected to explosion loads. Carrying out explosion-proof test is the most effective technical method for studying the explosion-proof protection of industrial plant structures. However, there are various types of industrial plant structures. According to the type of engineering materials, they can be divided into plant structures such as brick-concrete structure, reinforced concrete structure, and steel structure; according to different systems, they can be divided into rigid frame structure, bent frame structure, arch structure, etc.; the roof truss of the plant can also be divided into reinforced concrete truss, steel truss, wooden truss and other forms. It is impractical to carry out explosion-proof test research on such a variety of industrial plant structures. How to establish a universal and diverse explosion-proof test system to meet the actual needs of industrial plant structure explosion-proof protection research is a bottleneck problem that needs to be solved urgently. At present, explosion relief test systems are mainly divided into three categories: fixed volume device test system, fixed structure test system and detachable structure test system.
[0004] Fixed volume device test system mainly uses 20L ball or 1m 3 The cubic explosion container device is the main body, and the main body is filled with flammable materials such as gas and dust. After mixing with air, it is detonated by an ignition head, and an explosion vent is opened on it to realize the explosion venting behavior. The above system is not suitable for the explosion venting test research of industrial plant structures. The volume of the explosion chamber of the platform body is very limited, and its configuration is usually spherical or cubic, which is far from the structural form of an industrial plant. Its test structure is difficult to represent the reagent working conditions, and only some qualitative regularity research can be made.
[0005] Fixed structure test systems are mainly structure models made under full-scale or reduced-scale conditions. They are designed and manufactured according to the target working conditions. The test structure can represent the explosion-proof effect of the building under these conditions. However, this type of system cannot adjust the structural parameters and is only designed for a certain test condition. When conducting tests with different explosion-proof parameters or different structural configurations, it is often necessary to redesign the structure and perform processing, and its universality is poor.
[0006] The detachable structure experimental system is mainly composed of multiple unit structures spliced together or part of the structure can be disassembled and transformed to achieve a test system with changed working conditions. This type of system is more flexible in adjusting working conditions than the first two systems, but this type of system is mostly explosion-proof chambers or splicable pipes for mounting different test pieces, and is mostly used to carry out explosion tests on explosion-proof test pieces in fixed positions. Its explosion-proof measures can only be arranged at predetermined positions of the system. At the same time, this type of system cannot be disassembled to form building models of different configurations. The flexibility of adjusting the explosion-proof and structural parameters and the universality of the test system are still insufficient.
[0007] It can be seen that the existing explosion-proof test platforms have technical problems such as difficulty in adjusting the structural configuration, low flexibility in the arrangement of explosion-proof measures, and poor universality of the test platform.
