this paper analyzes the damage reasons of explosion-proof enclosure, and compares the difference between the explosion pressure the theoretical value and practical value. The explosion process of convex structure and square structure are simulated and analyzed by using the Fluent software, and it is found that the convex type structure of explosion pressure is 20% larger than the square structure. This is because the convex structure enhances the shock wave on the compression of unburned gas . Finally, this paper recommend Divided chamber , and the modified explosion-proof enclosure explosion-proof test.
