Application of Computer Environment Simulation Technology in Explosion Proof Equipment Experiment

Abstract

With the continuous development of science and technology, the explosion-proof technology is more and more perfect, but the explosion still exists. In view of the above situation, it is urgent to prevent the explosion and eliminate the hidden danger. At the same time, in order to avoid accidents in the research experiment, the computer environment simulation technology can be well applied. Usually, explosion-proof electrical equipment realizes explosion-proof safety through flameproof enclosure. The explosion-proof principle of flameproof electrical equipment is that the live parts of electrical equipment are placed in a special shell, which can isolate the sparks and arcs that may be generated by the electrical parts in the shell from the explosive mixture outside the shell. However, in the waste treatment of these electrical appliances, the shell will inevitably be mixed with various gases. In this paper, the combustion and explosion phenomena of explosion-proof electrical appliances in the process of explosion are studied and analyzed, and the computational fluid dynamics software FLUENT is used for simulation analysis, so as to realize the explosion-proof and explosion suppression function of explosion-proof electrical appliances. Based on the theory of gas explosion, this paper analyzes the mechanism of gas explosion in the use of electrical appliances. Assuming that the explosion source is a single methane gas, the explosion characteristic parameters such as explosion limit, explosion temperature and explosion pressure are theoretically estimated. The explosion limit is about 5.2%–14.3%, the explosion temperature is about 2883k, and the explosion pressure is about 0.87 mpa.
