The present invention relates to an air intake pipe for a ship engine that removes droplets of air by radiant heat of a heating element, and more particularly to remove droplets (small droplets) contained in air while minimizing pressure loss, such as an air intake pipe of a ship engine. The present invention relates to an air intake pipe for a ship engine that removes droplets in air by radiant heat of a heating element, which may be applied when necessary.

The method of separating the droplets by changing the flow of the gas, as shown in Figure 1, when the air flow direction is changed, the droplet having a larger mass than the gas particles separated from the gas flow by the centrifugal force separation plate (1) 1 is used to remove and collide with each other, and FIG. 1 shows the shape of various air suction pipes in which the separator 1 is formed.

Conventional techniques related to impingement droplet removal air suction tubes are disclosed in US Pat. Nos. 4,444,559, 52,526,23,526,011, etc., and the separator (1) capable of changing the gas flow in common, and the separator (1). It consists of a droplet collecting unit (2) capable of collecting droplets flowing separately separated by),

The purpose of the present invention is to increase the droplet removal efficiency by varying the size and shape of the separator 1 and the droplet collector 2, the bend angle of the separator 1 and the distance between the plates.

In particular, the air supplied to the marine engine includes a large amount of droplets, Figure 2 shows a cross-section of a conventional marine engine droplet removal air intake pipe.

That is, the air is supplied to the engine after the liquid droplets are separated while passing through the droplet separation plate 1 provided in multiple layers inside the suction tube 3 having the rectangular cross section or the suction tube 4 having the circular cross section.

However, in the case of the air suction pipes 3 and 4 provided with the droplet separation plate 1 as described above, the air flows rapidly by the separation plate 1 while the air passes through the droplet removal separation plate 1 composed of multiple layers. The problem of repeatedly experiencing a change in the pressure loss amount is also generated while colliding with the droplet collection unit (2).

Therefore, in the case of air intake pipes for ship engines, there is a need to supply air without droplets to the engine while minimizing pressure loss.

In order to solve the above problems, an object of the present invention is to provide an air suction tube for contacting and installing a reflection plate on the inner surface of the air suction tube, to install a heating element by electricity to remove the liquid droplets in the air by radiant heat.

In order to achieve the above object, the present invention is a heat-resistant reflective plate attached to the front surface of the inner wall surface; It provides an air suction tube for removing the droplets in the air by the radiant heat of the heating element, characterized in that the heating element of the electric heater type is installed at a predetermined interval of the horizontal or vertical form close to the reflecting plate.

In another aspect, the present invention is a heat-resistant and smooth surface of the aluminum material, the heating element of the electric heater type air is removed to remove the droplets in the air by the radiant heat of the heating element, characterized in that installed in the heat-resistant cylindrical quartz tube It will provide a suction line.

Hereinafter, with reference to the accompanying drawings will be described in detail the configuration of the present invention.

3 is a cross-sectional view of a ship engine air suction pipe for removing the droplets in the air by the radiant heat of the heating element according to the present invention, Figure 4 is a ship engine air suction pipe for removing the droplets in the air by the radiant heat of the heating element according to the present invention. A perspective view showing one surface of the in the longitudinal direction.

In the air suction pipe of the present invention, first, the reflection plate 6 is provided on the inner wall surface of the suction pipe.

Then, the plurality of heat generating elements 5 are arranged on the reflective plate 6 in a horizontal or vertical manner.

The heating element (5) is an electric heater method, the power line is extended to the outside of the air intake pipe (3, 4) so that power is supplied from the outside.

In addition, the reflector 6 is configured to have heat resistance while reflecting light to change the direction of heat to radiate.

In particular, the heating element (5) installed in the air intake pipe (3, 4) can be installed in a suitable direction according to the flow rate of the air and the flow rate of the air, the installation density is installed according to the amount of droplets contained in the incoming air Can be different.

Therefore, when a current is applied to the heating element 5 installed as described above, radiant heat energy is emitted from the surface of the heating element 5, and the emitted energy is continuously reflected by the reflection plate 6 installed therein, and the suction pipes 3 and 4 are provided. Can be absorbed by the air passing through it.

Since the droplets contained in the air actively absorb the radiant heat energy, the droplets may be evaporated and removed by the radiant heat emitted from the surface of the heating element 5 and the radiant heat reflected from the reflecting plates 6.

In addition, according to the present invention, since the air passes through the suction pipes 3 and 4 and does not experience a change in flow and collision with the droplet collecting unit as in the prior art, it is possible to increase the engine efficiency by supplying the engine without pressure loss.
