Spontaneous ignition point test device in high-pressure oxygen-rich environment

Abstract

The invention relates to a spontaneous ignition point test device in a high-pressure oxygen-rich environment. The spontaneous ignition point test device comprises an explosive vessel, a heating system, a vessel mounting and sealing protection device module, a pressure release device module, a high-pressure oxygen supply system and a pressure and temperature signal measuring and displaying module, wherein the heating system is arranged in the explosive vessel; the explosive vessel is arranged in the vessel mounting and sealing protection device module; the pressure release device module and the high-pressure oxygen supply system are respectively connected with the explosive vessel through the vessel mounting and sealing protection device module; and the pressure and temperature signal measuring and displaying module is connected with the explosive vessel. Compared with the prior art, the spontaneous ignition point test device disclosed by the invention can be used for measuring in real time, recording pressure and temperature information in the device and analyzing a spontaneous ignition point of a material to be tested under different oxygen-rich concentrations and pressures, and has the advantages of simple structure, convenience in mounting, high test efficiency, comprehensive data and the like.

Description

technical field [0001] The invention relates to a self-ignition point test device, in particular to a self-ignition point test device in a high-pressure oxygen-enriched environment. Background technique [0002] With the rapid development of my country's gas industry and the increasing demand for energy year by year, especially the wide application of clean energy, the production of low-temperature liquids such as liquefied natural gas, liquid hydrogen, liquid oxygen, liquid nitrogen, and liquid ethylene has shown rapid growth, which has promoted cryogenic The rapid development of the container industry. Ensuring the safe and effective operation of cryogenic containers has become the focus of common concern of the government, manufacturers and users. [0003] However, in the design and manufacture of cryogenic containers in my country, the very important compatibility of gas and materials (including materials in contact with storage and transportation media and materials for...

AI Technical Summary

Problems solved by technology

[0003] However, in the design and manufacture of cryogenic containers in my country, the very important compatibility of gas and materials (including materials in contact with storage and transportation media and materials for thermal insulation systems), chemical resistance, and chemical reactions caused by gas are often ignored. explosion and other issues

Designers of cryogenic containers often only pay attention to the physical properties and low-temperature thermal insulation properties of materials under cryogenic conditions, and do not take enough consideration of chemical reactions such as combustion between gases and materials, and lack scientific means and basis for judgment

Moreover, if the manufacturer of the cryogenic container chooses a material that is incompatible with the gas, it is likely to bring huge risks and hidden dangers of safety accidents
