Abstract: The present disclosure relates to a liquid oxygen vent silencer used in an oxygen production process implemented so as to eliminate potentially explosive elements, and the vent silencer is manufactured using copper plates and stainless (SUS) having no risk of explosions to minimize an edge that collide with oxygen gas, and includes a silencer body that receives cryogenic liquid gas and moves an internal space up and down to reduce noise; and a body support that is installed along an outside of the silencer body and supports the silencer body by raising or lowering the silencer body from a ground.
