Technical Field

[0001] The utility model belongs to the technical field of fire-resistant oil tanks, and in particular relates to a novel fire-resistant oil tank respirator. Background Art

[0002] The EH system is an important part of the steam turbine electro-hydraulic control system (DEH). It mainly consists of three parts: the oil supply system, the actuator and the emergency trip. The oil tank in the oil supply system is the main part for storing and processing fire-resistant oil. The oil supply system provides qualified fire-resistant oil to the actuator. The quality of the fire-resistant oil in the oil tank also directly affects the safe operation of the steam turbine.

[0003] The current fire-resistant fuel oil system has an unsatisfactory air filter effect, which leads to excessive moisture in the fire-resistant fuel oil and a high acid value, resulting in a series of impacts. The service life of the acid removal filter element is shortened. If the acid value rises to a more serious level, the fire-resistant fuel oil and corroded servo valves and other components need to be replaced. In addition, the air dehumidification device is inconvenient to install during use, affecting the efficiency of the equipment and increasing the installation cost. Utility Model Content
