What is the function of the water seal tank behind the hydrogen gas holder?
In an accident scenario, it serves as a safety water seal
As a supplementary note, it serves to create a separation when the system is parked or under maintenance, and its sealing performance is even better than that of valves.
It provides safety protection to prevent hydrogen backflow.
The natural pressure in a wet hydrogen gas holder is around a few thousand pascals. Installing water seals at the inlet and outlet constitutes a very effective safety measure; a sufficient depth of water can prevent the leakage of gas. Moreover, in the event of an accident, since gas can only enter or exit the holder through the water seals, this approach helps to prevent the entry of fire sources.
Could the experts please explain in detail its structure and principle? Thank you~~
Function of the water seal tank behind the hydrogen gas tank: 1. Safe discharge – when the hydrogen pressure on the inlet side reaches a certain level, some of the pressure can be released through the water seal. 2. Check valve: Gas on the outlet side of the water seal cannot penetrate to the inlet side of the water seal, while when the pressure on the inlet side is high, it can force its way through the water seal and out to the outlet side. This effectively prevents hydrogen from mixing with oxygen in the air to form an explosive mixture. 3. The effect of stable pressure. 4. Absorb, purify, and cool the gas on the inlet side.
It is mainly to prevent air from entering the hydrogen tank, thereby avoiding the formation of an explosive mixture.
