Labyrinth seal tandem dry gas buffer gas system

Tandem with intermediate labyrinth security seals dry gas seals seal buffer gas system
Sealed gas side seal dry gas seal is sealed using a filtered gas nozzle into a flush , as single-acting dry gas seal sealing sealing air system . From the dry gas seal leaking exhaust gas from the nozzle to the torch.
Labyrinth seal mounted in the middle of the torch nozzle to the gas supply pipe and a buffer between the mouth . Outside dry gas seals seals are used to prevent buffer gas leaking into the atmosphere. Using the electrical contact control differential pressure solenoid valve opening degree , to ensure a pressure buffer gas to the torch is always higher than the gas pressure , thus ensuring leak from the intermediate labyrinth seal is sealed with the gas discharge from the nozzle to the torch. If they are dry gas seal gas side seal failure , due to leakage of gas pressure , resulting in a buffer gas pressure increases ,cargo seal the intermediate labyrinth seal fluorine rubber seals to prevent leakage of gas leakage to the atmosphere . Leaking gas emissions to the flare .
