Description

Technical Field

[0001] The utility model relates to the field of water seal well structures, and particularly to a water seal well structure for preventing explosion spread. Background Technique

[0002] A water seal well is a safety liquid seal device, mainly used in the sewage pipe networks of factory areas with combustible gases, flammable liquid vapors or oil stains, to prevent the spread of combustion and explosion along the sewage pipe networks. The water seal well achieves the isolation purpose by utilizing the different densities of media or the different pressures inside and outside the sealed area. Its functions mainly include two aspects: one is isolation and plugging, preventing the overflow of the isolated medium or the mixing of external media, so as to achieve the functions of preventing environmental pollution or fire and explosion prevention; the other is to play a safety protection role, equivalent to a safety valve. There are various designs of water seal wells, including open water seal wells and closed water seal wells. There is a gap between the manhole cover and the well wall of the open water seal well, allowing the water inside and outside the well to flow freely, which is suitable for situations where it is necessary to keep the water flow unobstructed and the gas inside the well discharged. The closed water seal well is tightly sealed between the manhole cover and the well wall, not allowing water to flow in and out, which is suitable for situations where it is necessary to protect the environment inside the well from external pollution.

[0003] The water seal well structure for preventing explosion spread is based on the incompressibility and barrier property of water. By setting a certain depth of water seal in the pipeline system, the gas must pass through the water layer when passing through the pipeline. In this way, even if an explosion occurs in the pipeline, the explosion wave will be blocked by the water layer, thus preventing the explosion from spreading. However, most of the water seal well structures for preventing explosion spread only utilize the properties of water and gas itself for explosion prevention, and the designed structures can only be used for explosion prevention and cannot be used for the maintenance of the water seal well usually. Content of the Utility Model

[0004] The purpose of the utility model is to provide a water seal well structure for preventing explosion spread. The water seal well cover is fixed with the first water seal pipe and the second water seal pipe. When an explosion occurs, the shock wave generated by the explosion is eliminated partly by the first explosion-proof disc and the second explosion-proof disc, and then partly by the first explosion-proof holes and the second explosion-proof holes inside the first explosion-proof disc and the second explosion-proof disc. In addition to the function of eliminating the shock wave by the unique shapes of the first explosion-proof holes and the second explosion-proof holes, a collecting pipe is also provided, which can be used to collect garbage and sundries in the sewer usually.
