Embodiment Construction

[0027] 1. Install exhaust exhaust device at the stern of the ship. When the exhaust gas is discharged, you can choose whether to install a booster device according to the exhaust back pressure requirements of the main engine.

[0028] 2. The exhaust of the main engine of the ship is exhausted through the exhaust device, and a large number of exhaust gas bubbles are formed under the wake of the ship, which can quickly eliminate the tiny bubbles in the wake.

[0029] 3. There are multiple jet holes at the end of the exhaust device. By controlling the pressurization device or the discharge angle, the exhaust bubble group can completely cover the wake bubble area.

Abstract

The utility model relates to a method for utilizing the tail gas of a ship main engine for self-concealment and self-concealment, which belongs to the application field of ship stealth and exhaust gas recycling technology. This paper innovatively proposes to use a large amount of exhaust gas emitted by ships to suppress the number of wake bubbles. This technology treats the exhaust gas emitted by the main engine and discharges it underwater, which can make the high-temperature exhaust gas infrared and visually invisible. It can also use a large number of large bubbles released by the exhaust gas to effectively interfere with the wake bubbles of the ship by merging, carrying, and neutralizing the wake microbubbles, and continuously capture and attract the microbubbles in the wake to overcome them with greater buoyancy. The obstacle of turbulent flow quickly surfaced to achieve the effect of eliminating wake. This method reduces the space occupied by the ship and requires little modification to the hull structure. It is closer to actual use, and it is the simplest and most direct method to eliminate wake bubbles. In order to truly realize the application of the new technology of ship bubble wake suppression, it provides a more convenient way. This technology can fundamentally eliminate the wake bubbles of the ship, and has the advantages of rapid activation and flexible structure arrangement, which can be used as the exhaust wake elimination technology of the ship's main engine.

Description

technical field [0001] The invention relates to a self-concealment and self-concealment utilization method of ship main engine tail gas, which belongs to the application field of ship stealth and main engine tail gas recycling technology. Background technique [0002] The range of ship wake is large, the duration is long, it is not easy to eliminate, and it is not easy to camouflage. Moreover, there are more than a dozen physical fields in the wake of a ship, including bubble fields, as well as microwave, infrared, acoustic and optical fields, etc., and they will not be eliminated in a short time. For military operations, obtaining ship wake information plays a vital role, because a single ship target is easy to camouflage, but a wake with a large space range is difficult to avoid. The wake-homing torpedo is mainly based on the optical signal, magnetic signal, thermal signal, radioactive signal and bubble field signal of the wake. In the existing research, the bubble field...
