The present disclosure relates to a liquid oxygen vent silencer used in an oxygen production process, and more specifically, to a liquid oxygen vent silencer used in an oxygen production process implemented so as to minimize edges colliding with oxygen gas and eliminate potentially explosive elements.
Generally, a gas diffusing tower is installed in a gas base station. This gas diffusing tower is installed and used for the purpose of preventing safety accidents by discharging the gas remaining in a gas pipe to the atmosphere when maintenance is required due to an abnormality such as a gas leak in the gas pipe installed in the gas base station, causing the pressure inside the diffusing tower to exceed a set value.
This type of gas diffusing tower may be installed vertically at a height of about 20 to 30 m at a predetermined location on a gas pipe connection line of the gas base station, a scaffolding may be installed at a predetermined location on an outer side of a central portion and an outer side of an upper end portion of the diffusing tower so that a worker can climb up and perform the intended work, and a ladder may be installed from the ground to the scaffolding on the outer side of the upper end portion so that the worker can climb up to the scaffolding.
In addition, a lid is installed on the upper portion of the diffusing tower so that the lid can be opened and closed.
As described above, when gas leaks from the gas pipe and the gas pressure inside the diffusing tower rises above the set value, the lid of the gas diffusing tower is opened so that the gas inside the gas diffusing tower is discharged into the atmosphere, thereby preventing safety accidents such as gas explosions from occurring, and the gas pipe installed on the lower portion of the inside of the gas diffusing tower can be inspected or the remaining gas in the gas pipe can be discharged for maintenance.
However, in the related art, there is a problem that when gas leaked from the gas pipe through the gas diffusing tower and the gas pressure inside the diffusing tower increases above the set value, or when gas is discharged through the diffusing tower to perform maintenance and inspection of the gas pipe, high acoustic energy and strong pulse-type pressure waves (impulsive noise with a duration) are generated due to the speed and pressure of the gas discharged at high pressure and high speed.
Therefore, in order to solve the above problem, even in the related art, a silencer having built-in sound-absorbing material is installed at the upper end portion of the diffusing tower to reduce noise when gas is discharged.
However, even in this case, when low-pressure discharge gas with a flow rate of at least 30 m/sec or less flows into the silencer through the diffusing tower, the sound-absorbing material built into the diffusing tower is damaged by the high-temperature and high-pressure discharge gas and scattered, and thus, proper sound absorption cannot be achieved. In addition, there is a problem that the lifespan of the silencer is shortened and frequent maintenance is required.
