Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a soot-removing device that also serves as a fire extinguisher for exhaust gas pipes and smoke outlets of marine chimneys.

[Prior Art] Conventionally, an exhaust pipe of a marine chimney and a smoke outlet are equipped with a wire netting for preventing sparks from scattering, and the surroundings of the wire nettings to prevent scattering of the sparks cause the powder to be on the hull or at the berth or the like while moored. To prevent it from scattering. However, when soot is clogged in the wire scattering prevention wire mesh, a person climbs directly onto the chimney to remove the soot manually. Further, when the sparks are scattered through the gaps of the spark prevention wire mesh, a person is extinguishing the fire.

[Problems to be solved by the invention] According to the conventional technology, the work of removing soot clogging the wire mesh for preventing the scattering of sparks is poor because it requires manual work and high work. There is a problem in that it is not possible to remove soot and it is dangerous because the work of extinguishing the sparks from the wire mesh for preventing the scattering of the sparks is manual.

The present invention has been made in view of such problems of the conventional technology, and its purpose is to:
An object of the present invention is to provide a soot extinguishing apparatus for combined use of fire extinguishing, which enables remote and efficient soot removing work and fire extinguishing work of sparks.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention is directed to an exhaust gas pipe of a marine chimney and a flue outlet on the outer periphery of a wire mesh for preventing sparks scattered around the hood and installed. A ring pipe installed along the pipe, injection nozzles arranged at equal intervals at four locations on the ring pipe toward the wire mesh for preventing the sparks from scattering, and a fresh water pipe from the engine room that is switchably connected to the ring pipe, It is composed of a steam pipe and a compressed air pipe, and the fresh water pipe is used for extinguishing sparks and the steam pipe and the compressed air pipe are used for removing soot.

[Operation] When soot is clogged in the metal mesh for preventing the scattering of sparks attached to the exhaust pipe of the marine chimney and the smoke outlet, the soot is switched to the steam pipe or the compressed air pipe in the engine room and communicated with the ring pipe. Here, steam or compressed air is circulated to the ring tube, and steam or compressed air is jetted toward the wire dispersion preventing wire net from four injection nozzles arranged in the ring tube, and the wire powder preventing wire mesh is prevented. Remove the soot attached to the.

When the sparks are scattered from the wire mesh for preventing the sparks from being scattered, the sparks are switched to a fresh water pipe from the engine room and communicated with the ring pipe. Here, fresh water is circulated to the ring pipe, and fresh water is jetted from the spray nozzle toward the wire dispersion preventing wire net to extinguish the powder sparks from the wire dust preventing wire net.

[Example] An example will be described with reference to the drawings. As shown in Fig. 1, an outlet of an exhaust gas pipe 2 of a marine chimney 1 is surrounded by a wire mesh 3 for preventing sparks from being attached. As shown in FIG. 2, ring pipes 4 are attached along the outer circumference of the wire mesh 3 for preventing fire powder scattering, and injection nozzles 5 are arranged in the ring pipe 4 at four equal intervals toward the wire mesh 3 for preventing fire powder scattering. ing. The ring pipe 4 is switchably connected to the fresh water pipe 7, the steam pipe 8 and the compressed air pipe 9 from the engine room by a guide pipe 6.

In this embodiment, when soot is clogged in the wire dispersion preventing wire net 3 attached to the outlet of the exhaust gas pipe 2, the ring pipe 4 is switched to the steam pipe 8 or the compressed air pipe 9 which is installed from the engine room. Communicate with. Here, steam or compressed air is circulated up to the ring pipe 4, and steam or compressed air is jetted from the spray nozzles 5 arranged at four positions in the ring pipe 4 toward the wire dispersion preventing wire net 3 to prevent the powder scattering of fire powder. The soot adhering to 3 is removed.

Further, when the sparks are scattered from the sparks scattering prevention wire net 3, the sparks are switched from the engine room to the fresh water pipe 7 and communicated with the ring pipe 4. Here, the fresh water is circulated to the ring pipe 4, and the fresh water is jetted from the jet nozzle 5 toward the wire net 3 for preventing sparks scattering to extinguish the sparks from the wire netting 3 for preventing sparks scattering.

[Advantages of the Invention] Since the present invention is configured as described above, it has the following effects. In this device, since the soot-discharging pipe for also extinguishing the sparks is installed along the outer periphery of the wire mesh for preventing the scattering of sparks, the soot removing work and the extinguishing work of the scattered sparks are prevented. Can be done remotely,
Work safety can be improved, and soot removal work and fire extinguishing work can be performed from a short distance of the wire dust prevention wire net, and sufficient soot removal and fire extinguishing work can be efficiently performed.
