[0031] like Figure 1-4 As shown, the explosion-proof safety water seal device includes a cylinder a3 and a cylinder b20 on both sides. The upper side walls of the cylinder a3 and the cylinder b20 on both sides are connected to the flange 5 through a connecting pipe 6. A gas inlet 11 is arranged on the side of the cylinder b20 on one side, and a gas outlet 12 is arranged on the side of the cylinder a3 on the other side. The end of the air inlet pipe 7 connected to the gas inlet 11 extends to the lower end of the cylinder b20. The outer side wall of the lower part of the cylinder b20 is provided with a liquid level transmitter 8 and a magnetic flap liquid level gauge 9. The top of the cylinder b20 is provided with an automatic water replenishment port 14 and a manual water replenishment port 17. The lower outer side wall is provided with a manual overflow port 16. The bottom is provided with an automatic water discharge port 15. The top of the cylinder a3 is provided with an explosion relief port 13, and an explosion relief membrane 21 is provided in the explosion relief port 13.

[0032] The liquid level transmitter 8 on the outer wall of the cylinder b20 is provided with two upper and lower connection ports, which are respectively located on the upper and lower sides of the lower end of the air inlet pipe 7. The magnetic flap level gauge 9 on the outer wall of the cylinder b20 is arranged longitudinally, and the upper and lower level gauge ports are respectively located on the upper and lower sides of the lower end of the air inlet pipe 7.

[0033] The outer side walls of the cylinder a3 and the cylinder b20 are both provided with manholes 19. The bottoms of the cylinder a3 and the cylinder b20 are both provided with sewage outlets 18. The lower ends of the cylinder a3 and the cylinder b20 are end caps 2, the bottoms of the end caps 2 are provided with support seats 1, and the upper ends of the cylinder a3 and the cylinder b20 are provided with lifting ears 4. The outer side wall of the cylinder b20 is installed with an explosion-proof electric control box 10 through an electric control box bracket.

[0034] The working principle of this device when in use is mainly based on four principles: water seal principle, flameout principle, explosion-proof principle, and discharge principle. The water seal principle is that during the working process, this device is located at the explosion-proof point of the equipment pipeline, and the inside of the cylinder is filled with water or other liquids. When an explosion occurs in the pipeline, the flame will enter the interior of the device through the pipeline. The flame contacts the water or liquid inside the device to generate steam. Due to the large expansion capacity of steam, the speed and power of flame propagation can be effectively reduced through expansion and pressurization. At the same time, the water is heated and converted into steam to absorb the heat energy released by the flame, making it impossible for the flame to spread further.

[0035] The flame extinguishing principle is a prerequisite for the effective operation of the explosion-proof safety water seal. The steam generated by the contact between water and flame in this device can occupy the space of the device to form a fire barrier layer to extinguish the flame; the explosion-proof principle means that the explosion-proof safety water seal separates the flame from the explosive gas in the pipeline through its internal water seal layer, thereby preventing the explosive gas from spreading in the pipeline system. When an explosion occurs, the water seal layer of this device will act as a barrier, preventing the explosive gas from passing through the device to reach other areas, thereby preventing the possibility of the explosion spreading and ensuring that the explosion is limited to the inside of the explosion-proof device; the release principle means that there is an explosion-proof safety water seal with an explosion-proof membrane 21. When overpressure occurs, the explosion-proof membrane 21 ruptures and the pressure is released, thereby protecting other equipment.

[0036] The embodiments described above are merely descriptions of preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by those skilled in the art should be included in the protection scope determined by the claims of the present invention.
