Description

Technical Field

[0001] The utility model relates to the technical field of water seal tanks, in particular to a dry-wet combined explosion-proof water seal tank. Background Art

[0002] The water seal tank uses water pressure to achieve the anti-backfire function. The height of the water surface above the inlet cannot be less than 1.5 times the operating pressure. At the same time, the water level cannot be too high, otherwise it is easy to cause pressure build-up in the discharge pipe. Generally, an automatic water level adjustment system is set.

[0003] The water seal tank is equivalent to a safety valve. When the system is over-pressured, it can discharge excess pressure through the water seal tank to protect the system safety. To prevent the occurrence of backfire, after the flame enters the water seal tank through the pipeline, the inlet pipeline is below the water surface, which can prevent the flame from continuing to spread.

[0004] In chemical applications, it can ensure the gas flows forward and cannot flow back, which is equivalent to a one-way check valve; at the same time, if the equipment flashes back or explodes, the water seal tank can play a role of isolation to ensure the safety of the equipment. When necessary, water entering the tank can play a role of blocking the channel, because water has the most stringent sealing effect, and after the water seal is established, it is equivalent to a safety partition.

[0005] In the existing technology, in waste gas incineration application projects, some waste gases contain more impurities. After passing through the water seal tank, most of the impurities will remain inside the tank, causing the water seal tank to be blocked. The waste gas cannot be transported normally, causing the equipment to stop operating. When flashback occurs, due to the thick material of the water seal tank, effective explosion relief cannot be achieved, damaging the tank body. These are actual problems that need to be solved urgently. Utility Model Content
