Flow assist vent mast
| DWPI Title: Venting system for venting gas from storage tank for internal combustion engine in boats, has carrier gas tube for extending from proximal end that is fluidly connected to carrier gas source to distal end in vent mast outlet |
| Abstract: A venting system includes a vent valve in an opening of a storage tank, a carrier gas source for supplying a carrier gas, and a Vent Mast that has a Vent Mast outlet. The Vent Mast has a vent tube and a carrier gas tube. The vent tube extends from a proximal end connected to an outlet of the vent valve to a distal end in the Vent Mast outlet. The carrier gas tube extends from a proximal end connected to the carrier gas source to a distal end in the Vent Mast outlet. Vent gas flows through a vent gas lumen formed by the vent tube and carrier gas flows through a carrier gas lumen formed by the carrier gas tube. The carrier gas dilutes the vent gas and moves the vent gas higher (and thus away) from people and ignition sources. |
| Use: Venting system for venting gas from a storage tank for an internal combustion engine in boats and ships. Uses include but are not limited to hydrogen, nitrogen, oxygen and carbon dioxide. |
| Advantage: The system allows the vent mast to take benefits of a low momentum of a hydrogen flow at low velocity to control direction of the gas exiting the vent mast so that flammable gasses are directed away from a storage vessel and relatively rapidly dilute vent gas to inhibit a concentration of gas from exceeding flammability threshold e.g. 4 percentage hydrogen. The system prevents over-pressurization and possible rupture of the storage vessel, so that a portion of gas needs to be vented from time to time, or in a case of a fire threat. |
| Novelty: The system (100) has a vent valve (104) connecting to an opening (103) in a storage tank (102), where the vent valve comprises an outlet and the storage tank stores gas. A carrier gas source (116) supplies carrier gas, where the gas is different than the carrier gas. A vent mast (108) extends to a vent mast outlet (110). A vent tube (112) extends from a proximal end that is fluidly connected to the outlet of the vent valve to a distal end in the vent mast outlet, where the vent tube forms a vent lumen through which the gas from the storage tank flows. A carrier gas tube (114) extends from the proximal end that is fluidly connected to the carrier gas source to the distal end in the vent mast outlet, where the carrier gas tube forms a carrier gas lumen through which the carrier gas from the carrier gas source flows and a portion of the carrier gas tube extends parallel to and concentric to a vent gas tube. |
