Embodiment Construction

[0040] The specific implementation manners of the present invention will be further described below in conjunction with the drawings and examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0041] Such as Figure 1 to Figure 4 As shown, the present invention is a low-infrared radiation exhaust system for a high-speed assault boat, comprising a first exhaust pipe 1, an injector 2, a muffler assembly 3, a second exhaust pipe 5, a compensator 6 and Outlet pipe 7; injector 2 is made of double-walled pipe, and the nozzle height of the double-walled pipe near the muffler assembly 3 is lower than that of the double-walled pipe, which is far away from the nozzle of the muffler assembly 3, and the double-walled pipe is provided with Nozzle socket, the nozzle holder is installed on the nozzle socket. The muffler assembly 3 and the second exhaust pipe ...

Abstract

The invention discloses a low-infrared radiation exhaust system for a high-speed assault boat, which comprises a first exhaust pipe, an injector, a muffler assembly, a second exhaust pipe, a compensator and an outlet pipe connected in sequence; The wall pipe is composed of the pipe mouth of the double-wall pipe close to the muffler assembly, which is lower than the mouth of the double-wall pipe far away from the muffler assembly. The double-wall pipe is provided with a nozzle socket, and a nozzle holder is installed on the nozzle socket. The invention adopts seawater to cool the exhaust gas, which improves the sound-absorbing performance, reduces the discharge of harmful components in the exhaust gas into the atmosphere, and increases the safety on board. The seawater injection also reduces the exhaust volume flow rate, so the weight and size of the exhaust system can be reduced; the installation method of the system is designed ingeniously to avoid the deformation of the system exhaust pipe and other pipelines during the installation process or the damage during installation.

Description

technical field [0001] The invention relates to a low-infrared radiation exhaust system of a high-speed assault boat and an installation method thereof. Background technique [0002] Fossil fuels are used in internal combustion engines such as diesel engines and boilers. With the combustion of fossil fuels, exhaust gas containing NOX, SOX, oil, and fine particles is generated, which becomes a source of environmental pollution. Therefore, people try to reduce environmental pollution sources in exhaust gas by improving fuel, increasing combustion efficiency, introducing exhaust gas treatment equipment, and the like. [0003] Regarding facilities that exist on land such as vehicles, factories, or thermal power plants, improvements have been largely made. [0004] However, in ships that run on seas or rivers, the exhaust volume of engines is much larger than that of automobiles, and there is almost no remaining space where exhaust gas treatment equipment can be installed. Als...
