  Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. Here, repeated descriptions, detailed descriptions of known functions and configurations that may unnecessarily obscure the subject matter of the present invention are omitted. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the invention to those skilled in the art. Accordingly, the shape and size of elements in the drawings may be exaggerated for a clearer description.

  FIG. 1 is a schematic view showing an embodiment of a mist removing device for an atmospheric vaporizer according to the present invention, and FIG. 2 is a plan view showing an embodiment of the mist removing device for an atmospheric vaporizer according to the present invention. FIG.

  Referring to FIGS. 1 and 2, the fog removal apparatus for an atmospheric carburetor according to the present invention is a mist diffusion prevention wall that surrounds the atmosphere carburetor 10 while being spaced apart from the outer surface of the atmospheric carburetor 10. Including the body 20;

  The atmospheric carburetor 10 is connected to an LNG storage tank, receives LNG from the LNG storage tank and vaporizes it, and the vaporized NG is sent to a gas supply management station via an LNG header and a measuring facility. To do.

  The atmospheric carburetor 10 includes a vaporization channel (not shown) that allows LNG to flow and transfer from the top to the bottom of the carburetor body, and the carburetor body at the top of the carburetor body. An air suction fan 11 that sucks air into the interior of the carburetor, and sucks air into the carburetor body from the upper side of the carburetor body via the air suction fan 11 to lower the carburetor body. The LNG moving in the vaporization flow path and the atmosphere are heat-exchanged while being discharged, and the LNG is vaporized. This is the same as the structure of the normal atmospheric vaporizer 10, and thus more detailed. It is made clear that explanation is omitted.

  The fog diffusion preventing wall body 20 may have a circular shape surrounding the atmospheric vaporizer 10, and may include a plurality of walls connected to surround the atmospheric vaporizer 10.

  When the atmospheric vaporizer 10 is operated, fog is artificially generated in the vicinity due to a difference in atmospheric temperature and humidity.

  Artificial fog generated during the operation of the atmospheric vaporizer 10 not only increases in density in proportion to its size, but also has the property of increasing latent heat of vaporization. Nitrogen (28 g / mole) and oxygen in the atmosphere (32 g / mole), the weight of air is determined, and it is heavier than air and sinks only when the size of the artificial mist is about 0.7 mm or more.

  The present invention is provided with a fog diffusion preventing means 30 at the lower part of the fog diffusion preventing wall 20, and the fog diffusion preventing means is naturally generated by an atmospheric flow of fog generated artificially during the operation of the atmospheric vaporizer 10. 30 is passed through and removed.

  Referring to FIG. 3, the fog diffusion preventing means 30 is a mesh network in which fog is removed as the fog generated inside the fog diffusion preventing wall 20 moves and passes naturally by the flow of the atmosphere. 31 may be sufficient.

  Further, the mist diffusion preventing means 30 may be a mist removal filter that removes mist by the mist generated inside the mist diffusion preventing wall 20 moving and passing naturally by the flow of the atmosphere. Good.

  More specifically, a fog passage hole is formed in the lower part of the fog diffusion prevention wall body 20, and the mesh net 31 or the fog removal filter is attached to the fog passage hole, and the inside of the fog diffusion prevention wall body 20. The mist generated in (3) is naturally moved by the atmospheric flow and is removed by passing through the mesh net 31 or the mist removal filter.

  When the atmospheric carburetor 10 is operated, the atmosphere is sucked from the upper part of the carburetor main body and discharged to the lower part of the carburetor main body. Therefore, the flow of the air discharged to the lower part of the carburetor main body. Also, the mist generated inside the fog diffusion preventing wall 20 is moved more naturally so as to pass through the mesh net 31 or the mist removal filter.

  The mesh net 31 removes the mist by adhering moisture in the mist by heat exchange while the mist passes.

  That is, not only the air flow caused by the operation of the atmospheric suction fan 11 disposed at the upper part of the carburetor body, but also the amount of air flowing in by the inertial force, the mist diffusion prevention wall during the operation of the atmospheric carburetor 10. The mist generated inside the body 20 can be naturally removed through the mesh net 31 or the mist removal filter.

  On the other hand, in FIGS. 4 and 5, it is preferable that the fog diffusion preventing means 30 removes fog by a hydrophilic method. The prevention of fog diffusion by the hydrophilic method is less energy consumption and less maintenance and management costs than when removing fog by the heating method and mixing method, and maximizes the properties of water. There is an advantage that it can be used.

  Referring to FIG. 4, the fog diffusion preventing unit 30 connects the water tray member 32 in which water is stored, the water tray member 32 and the lower part of the fog diffusion preventing wall 20, and A mist transfer pipe member 34 that supplies the mist in the fog diffusion prevention wall body 20 to the water stored in the water tray member 32, and is attached to the mist transfer pipe member 34, A blower fan 35 that sucks the mist into the mist transfer pipe member 34 and discharges the mist into the water stored in the water tray member 32.

  That is, the mist diffusion preventing means 30 sucks the mist generated inside the mist diffusion preventing wall body 20 through the mist transfer pipe member 34 when the atmospheric vaporizer 10 is operated, and the water tray member. It is discharged into the water in 32 and removed.

  Referring to FIG. 5, the fog diffusion preventing means 30 includes a combustion type vaporizer 33, a combustion type vaporizer 33 and a lower part of the fog diffusion prevention wall body 20, and the fog diffusion prevention wall body. A mist transfer pipe member 34 for supplying the mist in the mist 20 to the water stored in the combustion vaporizer 33, and the mist transfer pipe member 34 attached to the mist transfer pipe member 34. And a blower fan 35 that is sucked into the transfer pipe member 34 and discharged into the water stored in the combustion type vaporizer 33.

  Although not shown, the combustion-type vaporizer 33 is filled with water as a vaporization medium fluid inside the vaporizer body, passes through the vaporization medium fluid and moves the LNG, and heats the vaporization medium fluid. A heating channel is formed.

  The vaporization medium fluid in the combustion type vaporizer 33 vaporizes air heated by a burner or the like into the heating flow path, or vaporizes LNG passing through the vaporization flow path above a preset temperature. Maintained at the allowed temperature.

  The combustion type vaporizer 33 has an example of a structure that vaporizes the LNG by heat exchange with the vaporization medium fluid, that is, water, while moving LNG to the vaporization flow path. Since it is the same as the structure of the vaporizer 33, it will be clarified that a more detailed description is omitted.

  Since the combustion type vaporizer 33 is mainly used only in winter, the fog generated inside the fog diffusion preventing wall 20 when the atmospheric type vaporizer 10 is in operation when the atmospheric type vaporizer 10 is not operated except in the winter. It is preferably used to remove the mist by being sucked through the mist transfer pipe member 34 and discharged into the water stored therein.

  The present invention prevents the fog generated around the atmospheric carburetor 10 from spreading and diffusing to the outside during the operation of the atmospheric carburetor 10, thereby ensuring a peripheral visual field.

  The present invention provides a traffic jam that can occur while fog spreads widely around the atmosphere-type vaporizer 10, particularly by ensuring a visual field around the atmosphere-type vaporizer 10 provided in a large-scale LNG storage facility. Prevent the occurrence of various safety accidents such as traffic accidents.

  Of course, many other modifications are possible to those skilled in the art within the scope of the basic technical idea of the present invention, and the scope of the present invention is attached. Should be construed on the basis of the appended claims.
