Existing event recyclers for oil vapor in settling process

摘要

The present invention relates to a device for recovering hydrocarbon vapor from a buried container without changing the container, for example, providing equipment for a battlefield service station at a lower cost by reducing the impact on the environment, fire or fire risk. blast Consisting of caissons mounted on The existing vent is cut off by the pressure of the steam entering the vessel due to venting, but the other vessel (. 7) cannot be pressurized through the vent valve. The steam is depressurizedDue to the volume difference between the ventilation duct and the caisson volume, and the temperature drop of the cooling elements (6). The steam passes through an adapter（ (3) nozzles (() 2) with fail safe valves release steam in the event of an accident.
