Definitions

  • the present invention relates to ships and more especially the exhaust of said vessels.
  • Air exhaust has the disadvantage of being noisy, generate unpleasant smells and create plumes of smoke which are not aesthetic and are easily identifiable.
  • Submarine exhausts only work at high speeds (generally at speeds above 9 knots) are placed near the waterline and have an outer part called deflector or "spoon" outside to prevent the entry of water into the exhaust and protect the engines against the pressure exerted by the water.
  • This system although easy to perform, is very sensitive to movements of the ship and the swell, as there is a risk introduction of water into the engines.
  • the position close to the line of flotation creates a risk of blockage by ice deterioration of the external duct by floating objects or simply the edge of the dock. Odors are not totally suppressed because of the low dispersion of the gases in the water.
  • the movement of the ship and the swell can clear the escape of the water the smoke is then directly in the air.
  • the object of the present invention is to propose a device underwater exhaust at the same time simple, operating at low speed and releasing little smoke in the air near the ship.
  • the underwater escape device is consisting of an exhaust box connected to the evacuation network gases via an exhaust pipe, said box is disposed at level of an exhaust outlet located on the hull of a ship she is equipped with a baffle located tangentially to said hull.
  • the tangential deflector gives a smooth profile to the hull of the ship which allows to go into submarine mode at low speeds and which avoids the risk of collision with floating objects.
  • the deflector has the shape of an inverted spoon.
  • the shape substantially convex from the outside of the spoon accelerates the flow of the interior of the exhaust and promotes the evacuation of water, while the shape hollow from the inside of the spoon takes off the water nets from the hull and creates a ventilation zone at the back of the profile.
  • the profile ensures a sufficient vacuum zone inside the duct exhaust for the evacuation of gases.
  • the deflector has a width horizontal equivalent to 2/3 of the horizontal width of the exit exhaust. This size is optimal to facilitate the evacuation of gas without driving water inlet into the exhaust box.
  • the exhaust duct is horizontal.
  • the exhaust is placed below the waterline.
  • the very deep position of the exhaust outlet makes it possible to reduce external noise, discharges into the atmosphere, and to remove both the risk of passage in the open in case of ship movements or swell and the risk to be caught in the ice.
  • the exhaust is located at more 50cm from the waterline.
  • the exhaust duct makes a angle of 30 to 40 ° with respect to the hull of the ship. This inclination horizontal exhaust duct relative to the baffle allows flow optimization.
  • the ship 1 has an exhaust 2 disposed below the level of the waterline 3 at a distance from said surface (cf. figure 1).
  • the exhaust 2 comprises an exhaust pipe 4 and connected to the exhaust network 8 of the gases and a box 5 arranged inside at the exhaust outlet 7 and not exceeding not the hull 10 of the ship 1 (see Figure 2).
  • the duct 4 and the box 5 angle ⁇ with the shell 10.
  • the angle ⁇ is measured from the front portion 10a of the hull 10 and is between 30 and 40 °.
  • the box 5 is partially closed by a deflector 6 fixed on the side of the box 5 at the level of the part before 10a.
  • the deflector 6 is oriented towards the front of the ship 1 of such way that when moving the vessel 1 the water inlet is minimal.
  • the deflector 6 has the shape of a spoon whose hollow part 60 is in the extension of the part 10a of the hull 10 and directed to the outside of the ship 1.
  • the convex part 61 is placed inside of the hull 10.
  • the two faces 60 and 61 of the deflector 6 converge towards the rear of the ship 1 so that the front face 62 of the deflector 6 is wider than the rear part 63.
  • the network Exhaust 2 goes into submarine mode by opening or not valve (not shown) disposed further upstream and the gases exit through the duct 4 and the box 5 where the depression is sufficient to receive the exhaust gas.
  • the profile 61 directs the gases towards the rear of the vessel 1 and part 60 deflects the water streams in such a way that both flows are almost tangent when they come in contact with each other the other, which also promotes flow and limits drag.
